[Spacemacs, Bootstrap] Rename files 
Rename `installation.org' to `bootstrap.org' since it better describes
what it is for.

Rename `emacs.org' to `spacemacs.org', preparing for the new
`emacs.org' dedicated to my vanilla config.

:END:
This file is the main source file for my Emacs configuration which contains most
of the user code. It is exported thanks to Emacs’ code tangling from the
original Org file which you can find on my dotfiles’ repository[fn:1] if you are
reading the web version of it. You can also find there my ~.spacemacs~[fn:2] and
its code which isn’t part of the present file. As you can see in my
~.spacemacs~, at init-time, if Emacs detects the tangled configuration files are
older than the Org file, then Emacs tangles them again, and then loads them.
* Spacemacs layers and packages
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-6d318b87
:header-args:emacs-lisp: :mkdirp yes :tangle ~/.emacs.spacemacs/private/spacemacs-layers.el :exports code :results silent :lexical t

Here will be our layer configuration set. Everything here is set with a
~setq-default~ in the ~dotspacemacs/layers~ function like so:
#+BEGIN_SRC emacs-lisp :tangle no
(defun dotspacemacs/layers ()
(setq-default
;; configuration goes here
))
#+END_SRC
** General configuration
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-General_configuration-66b4311e
:END:
First, we need to tell Spacemacs which base distribution we are using. This is a
layer contained in the directory ~+distribution~. For now, available
distributions are ~spacemacs-base~ and ~spacemacs~ (the default one).
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-distribution 'spacemacs)
#+END_SRC
We can seet a lazy installation of layers —i.e. layers are installed only when a
file with a supported type is opened. Possible values are:
- ~all~ :: will lazy install any layer that support lazy installation even the
layers listed in ~dotspacemacs-configuration-layers~
- ~unused~ :: will lazy install only unused layers (i.e. layers not listed in
the variable ~dotspacemacs-configuration-layers~)
- ~nil~ :: disables the lazy installation feature and you have to explicitly
list a layer in the variable ~dotspacemacs-configuration-layers~ to install
it.
The default value is ~unused~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-enable-lazy-installation nil)
#+END_SRC
If the following variable is non-nil, Spacemacs will ask for confirmation before
installing a layer lazily. The default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-ask-for-lazy-installation t)
#+END_SRC
** Package management
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Package_management-0add1a62
:END:
It is possible to indicate to Spacemacs a list of additional paths where to look
for configuration layers. Paths must have a trailing slash, i.e.
=~/.mycontribs/=. As you can see, I added only one:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layer-path
'("~/fromGIT/emacs-packages"))
#+END_SRC
However, I do have additional packages I installed either from the Elpa or the
Melpa. These are set in ~dotspacemacs-additional-packages~, a list of additional
packages that will be installed without being wrapped in a layer. If I need some
configuration for these packages, then I should consider creating a layer. I can
also puth the configuration in ~dotspacemacs/user-config~. To use a local
version of a package, use the ~:location~ property, for instance:
#+BEGIN_SRC emacs-lisp :tangle no
'(your-package :location "~/path/to/your-package/")
#+END_SRC
With the variable ~dotspacemacs-additional-packages~, it is possible to install
extra packages which are not already included in any layers. Dependencies should
be explicitly included as they won’t be resolved automatically. Here is a table
of all the extra packages I use:
#+NAME: extra-packages
| name of the package | why is it installed |
|----------------------------+--------------------------------------------------------|
| caddyfile-mode | Major mode for editing Caddyfiles |
| dired-git-info | Git information in Dired buffers |
| diredfl | Extra font lock rules for a more colourful dired |
| edit-indirect | edit region in separate buffer |
| elcord | rich integration of Emacs in Discord |
| eshell-syntax-highlighting | Syntax highlighting for Eshell |
| info-colors | Extra colors for Emacs's Info-mode |
| multiple-cursors | I don’t like the layer, I prefer this package alone |
| ob-latex-as-png | Inline arbitrary LaTeX snippets as PNGs in Emacs |
| org-sidebar | display on the side the outline of an Org buffer |
| org-tree-slide | presentation tool for org-mode |
| outorg | edit comments as Org-mode buffers |
| ox-ssh | SSH config export for org-mode |
| pinentry | enter a GPG password from Emacs |
| nord-theme | An arctic, north-bluish clean and elegant Emacs theme. |
| s | The long lost Emacs string manipulation library. |
| sicp | Texinfo version of the [[https://mitpress.mit.edu/sites/default/files/sicp/index.html][SICP]] |
| visual-fill-column | allow the use of ~fill-column~ in ~visual-line-mode~ |
| wrap-region | easily wrap region with delimiters |
| wttrin | weather in Emacs |
| yasnippet-snippets | snippets for YaSnippet |
#+name: make-extra-pkg
#+begin_src emacs-lisp :var packages=extra-packages[,0] :tangle no :exports none
(mapcar 'make-symbol packages)
#+end_src
#+begin_src emacs-lisp :noweb yes :exports none
(setq-default dotspacemacs-additional-packages '<<make-extra-pkg()>>)
#+end_src
It is possible to also list packages that cannot be updated:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-frozen-packages '(helm-icons))
#+END_SRC
And to list packages which won’t be installed nor loaded:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-excluded-packages '(company-tern))
#+END_SRC
Finally, it is possible to define the behaviour of Spacemacs when installing
packages. Possible values are:
- ~used-only~ :: installs only explicitly used packages and deletes any unused
packages as well as their unused dependencies
- ~used-but-keep-unused~ :: installs only the used packages but won’t delete
unused ones
- ~all~ :: installs *all* packages supported by Spacemacs and never uninstalls
them.
The default value is ~used-only~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-install-packages 'used-only)
#+END_SRC
** Layers
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-36e1c90c
:END:
All layers are set one variable: ~dotspacemacs-configuration-layers~. This
variable is a list of layers, some of them will have some custom variables.
Typically, the variable will be set like so:
#+BEGIN_SRC emacs-lisp :tangle no
(setq-default dotspacemacs-configuration-layers
'(emacs-lisp
helm
multiple-cursors
org
(shell :variables shell-default-height 30
shell-default-position 'bottom)
treemacs))
#+END_SRC
# Don’t delete this code block, it wraps the layers
#+BEGIN_SRC emacs-lisp :exports none
(setq-default dotspacemacs-configuration-layers '(
#+END_SRC
*** Checkers
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Checkers-aefeae26
:END:
The two first checkers I use are for spell and syntax checking. ~spell-checking~
is disabled by default, however it should auto-detect the dictionary to use.
#+BEGIN_SRC emacs-lisp
(spell-checking :variables
spell-checking-enable-by-default nil

syntax-checking
#+END_SRC
*** Completion
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Completion-883e2b83
:END:
~auto-completion~ is a layer enabled in order to provide auto-completion to all
supported language layers. It is set so that the =RET= key has no behavior with
this layer, however the =TAB= key cycles between candidates displayed by the
auto-completion toolbox. I also want the autocompletion to include snippets in
the popup, and the content of the popup is sorted by usage. It is also disabled
for two modes: magit and Org.
#+BEGIN_SRC emacs-lisp
(auto-completion :variables
auto-completion-complete-with-key-sequence-delay 0.2
auto-completion-enable-help-tooltip 'manual

#+END_SRC
~helm~ is also enabled, with its header disabled.
#+BEGIN_SRC emacs-lisp
(helm :variables helm-no-header t)
#+END_SRC
*** Email
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Email-67c16308
:END:
I use as my daily Email client ~mu4e~, so let’s enable it and tell Emacs where
mu4e is installed. I also tell mu4e to use maildirs extensions, use async
operations, where to keep attachments, and enable the mu4e modeline.
#+BEGIN_SRC emacs-lisp
(mu4e :variables

*** Emacs
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Emacs-8e976e5c
:END:
The first layer enabled in this category is ~better-defaults~. I also made it so
that when a command equivalent to ~C-a~ or ~C-e~ is pressed, the cursor will
respectively first move to the beginning of code first before going past the
indentation and to the end of the code before going to the end of the line
before going over the end of the comments on the same line.
#+BEGIN_SRC emacs-lisp
(better-defaults :variables
better-defaults-move-to-beginning-of-code-first t
better-defaults-move-to-end-of-code-first t)
#+END_SRC
I also enabled ~ibuffer~ and made it so that buffers are sorted by projects.
#+BEGIN_SRC emacs-lisp
(ibuffer :variables
ibuffer-group-buffers-by 'projects)
#+END_SRC
Most important of all, the ~org~ layer is also enabled. I enabled support for
Epub exports, Github, Reveal.JS exports, and sticky headers. Project support is
also enabled through files named ~TODOs.org~. I also set the org-download folder
for images in =~/Pictures/org/=, and I set the =RET= key to follow org links if
the cursor is on one.
#+BEGIN_SRC emacs-lisp
(org :variables
org-enable-epub-support t

#+END_SRC
The ~semantic~ layer is also enabled.
#+BEGIN_SRC emacs-lisp
semantic
#+END_SRC
*** File trees
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-File_trees-5b6ed3e4
:END:
In this category, I only enabled one layer: ~treemacs~. In this layer, I set is
so that treemacs syncs with my current buffer, and it automatically refreshes
its buffer when there is a change in the part of the file system shown by
treemacs.
#+BEGIN_SRC emacs-lisp

#+END_SRC
*** Fonts
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Fonts-11de8977

**** Domain-specific (DSLs)
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Programming_languages-Domain-specific_(DSLs)-2c919937
:END:
In this category, I enabled support for the ~major-modes~ layer for the Arch
Linux PKGBUILDs support, ~emacs-lisp~ and ~scheme~ layers, support for the CSV
format with the ~csv~ layer, the ~yaml~ language, shell scripting languages and
support for the ~dot~ tool with the ~graphviz~ layer.
#+BEGIN_SRC emacs-lisp
major-modes emacs-lisp scheme graphviz yaml shell-scripts
#+END_SRC
I also added support for HTML and CSS with the ~html~ layer, with the web
formatting tool set to ~web-beautify~, and the LSP layer compatibility enabled
for CSS, less, SCSS and HTML.
#+BEGIN_SRC emacs-lisp
(html :variables

The ~json~ layer is also enabled, with the format tool set to ~web-beautify~.
#+BEGIN_SRC emacs-lisp
(json :variables

#+END_SRC
The LaTeX layer has also been enabled, with its default compiler set to XeLaTeX.
I also enabled the auto-fill feature, the folding capacity and the “magic”
symbols.
#+BEGIN_SRC emacs-lisp
(latex :variables
latex-build-command "xelatex"
latex-enable-auto-fill t
latex-enable-folding t

#+END_SRC
PlantUML is a very useful DSL for creating UML diagrams from some text
description. As you can see below, this layer will be enabled, both as a
standalone mode for opening ~.pum~ files, but also for org-mode code blocks.
#+BEGIN_SRC emacs-lisp
(plantuml :variables
plantuml-jar-path "~/.local/bin/plantuml.jar"

**** General-purpose
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Programming_languages-General-purpose-1ed71a5b
:END:
Among the layers I activated, the only one without any specific configuration is
the ~asm~ layer for the Assembly language.
#+BEGIN_SRC emacs-lisp
asm
#+END_SRC
Next, you can find the C/C++ layer for which I set the default language for ~.h~
files to be C. I also enabled support for subprojects and organization of the
include directives on a file save. I also set a couple of LSP-related variables,
such as the LSP executable for C/C++ for its CCLS backend and some highlight
variables.
#+BEGIN_SRC emacs-lisp
(c-c++ :variables

#+END_SRC
Dart has also been enabled, with a custom path to the SDK of the Dart server,
and to the LSP server of Dart.
#+BEGIN_SRC emacs-lisp
(dart :variables
lsp-dart-project-sdk-dir "/opt/dart-sdk/"
lsp-dart-sdk-dir "/opt/dart-sdk/")
#+END_SRC
When it comes to the Python layer, I set its backend and formatter to be bound
to the LSP layer. Its fill columnn was also set to 80 characters, imports are
sorted on save, and the tests can be run using either nose.el or pytest.
#+BEGIN_SRC emacs-lisp
(python :variables
python-fill-column 80
python-test-runner '(pytest nose))
#+END_SRC
With the Rust layer, the only custom configuration set is the backend being
bound to the LSP layer.
#+BEGIN_SRC emacs-lisp
(rust :variables rust-backend 'lsp)
#+END_SRC
As regards the JavaScript layer, I set its backend to the LSP layer, and bound
its format tool to ~web-beautify~ and its REPL is browser-based. I also want to
include ~node_modules/.bin~ to be automatically added to the buffer local
~exec_path~.
#+BEGIN_SRC emacs-lisp
(javascript :variables
javascript-backend 'lsp
javascript-fmt-tool 'web-beautify

#+END_SRC
Alternatively, I also use Typescript which is a sort of better Javascript as it
should have been, with the LSP backend.
#+BEGIN_SRC emacs-lisp
(typescript :variables

In this category, only the ~epub~ and ~pdf~ layers are enabled without any
special configuration, so I can read these files from Emacs directly.
#+BEGIN_SRC emacs-lisp

**** Elfeed
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Readers-Elfeed-78877179

#+END_SRC
*** Themes
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Themes-d88d1225

Here, the ~colors~ layer is the only one enabled. It activates support for
identifiers colorization, and strings representing colors.
#+BEGIN_SRC emacs-lisp

#+END_SRC
*** Tools
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Tools-e57e405e

In this category, the first layer to be enabled is the CMake layer for which I
enabled support for the ~cmake-ide~ package.
#+BEGIN_SRC emacs-lisp
(cmake :variables
cmake-enable-cmake-ide-support t)
#+END_SRC
Next, we have the Docker, Nginx, Pass (the standard Unix password manager),
Prettier, Systemd, Meson, Imenu-list, Web-beautify, Dap, and Helpful.
#+BEGIN_SRC emacs-lisp
dap docker helpful imenu-list meson nginx pass prettier systemd web-beautify

Of course, let’s not forget about the awesome LSP layer:
#+BEGIN_SRC emacs-lisp
(lsp :variables lsp-lens-enable t
lsp-use-lsp-ui t
lsp-rust-server 'rust-analyzer)
#+END_SRC
We also have the RestClient layer enabled for which I enabled the Org
compatibility support.
#+BEGIN_SRC emacs-lisp

And finally, we also have the Shell layer for which I specified its default
height when spawning at the bottom of the screen should be 40 lines high, and
the default shell to invoke is Eshell.
#+BEGIN_SRC emacs-lisp
(shell :variables

The ~dotspacemacs/init~ function is the one called at the very begining of the
Spacemacs startup, before any kind of configuration, including the layer
configuration. Only the values of the Spacemacs settings should be modified
here. By default, every values are set in a ~setq-default~ sexp, and they
represent all the supported Spacemacs settings. Hence, the function looks like
this:
#+BEGIN_SRC emacs-lisp :tangle no

Just before we get onto the usual content of the ~dotspacemacs/init~ function
you would find in a typical Spacemacs installation, I would like to talk a bit
about how I manage writing a litterate config for Spacemacs and ensure Emacs
starts with an up-to-date configuration from said litterate config. For that, I
actually declared a couple of variables:
#+BEGIN_SRC emacs-lisp
(defvar phundrak--dotspacemacs-src-dir "~/.emacs.spacemacs/private/"
"Directory for my exported Elisp configuration files")

I also declared the following function that tells me if my Elisp files are more
recent than my ~emacs.org~ file. The ~compiled?~ argument lets me compare either
the ~.el~ files if it is ~nil~, or the ~.elc~ files if it is ~t~.
#+BEGIN_SRC emacs-lisp

Now I know a couple of my files that get exported by this document. If I compare
how recent these files are compared to my litterate config, I know if Emacs
missed tangling its configuration before launching, so if any of my ~si~, ~sl~,
~uc~, or ~ui~ files are older than my ~emacs.org~, then I’ll tangle the latter;
and since my user config is growing longer and longer, I want Emacs to be able
to parse it fast next time it boots, so let’s compile my exported ~.el~ files!

All that’s left to do in the Spacemacs functions is to call ~load~ on ~si~,

not be up to date with the [[https://labs.phundrak.com/phundrak/dotfiles/src/branch/master/.spacemacs][actual dotspacemacs file]]. Please check it just in
case something changed and I forgot to update this part of ~emacs.org~.
** Emacs with pdumper
:PROPERTIES:
:CUSTOM_ID: Init-Emacs_with_pdumper-f24ab30b
:END:
It is possible to compile Emacs 27 from source with support for the portable
dumper, as shown in Spacemacs’ ~EXPERIMENTAL.org~ file. I do not use this
feature yet, as I am still on Emacs 26 provided from Arch Linux’s repositories,
so I’ll disable the Spacemacs support for this feature. The default value of
this variable is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-enable-emacs-pdumper t)
#+END_SRC
In case the support for pdumper was enabled, Spacemacs needs to know the name of
the Emacs executable which supports such a feature. The executable must be in
the user’s ~PATH~. By default, the value of the variable is ~"emacs"~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-emacs-pdumper-executable-file "emacs")
#+END_SRC
And finally, we can name the Spacemacs dump file. This is the file that will be
created by the portable dumper in the cache directory under the ~dumps~
sub-directory. To load it when starting Emacs, the parameter ~--dump-file~
should be added when invoking Emacs 27.1 executable from the command line, for
instance:
#+BEGIN_SRC sh :tangle no :exports code
./emacs --dump-file=~/.emacs.spacemacs/.cache/dumps/spacemacs.pdmp
#+END_SRC
The default value of this variable is ~"spacemacs.pdmp"~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-emacs-dumper-dump-file
(format "spacemacs-%s.pdmp" emacs-version))
#+END_SRC
** Package managment and updates
:PROPERTIES:
:CUSTOM_ID: Init-Package_managment_and_updates-79363da3
:END:
Spacemacs’ core configuration can be updated via git commands using Github
services. If Spacemacs is not set to the ~develop~ branch, it can check by
itself if any update is available. However, I am using said branch, therefore I
should set this variable to ~nil~. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-check-for-update nil)
#+END_SRC
When it comes to package management, Spacemacs is able to store them in
different directories depending on the version of Emacs used or based on other
variables. I personally prefer to use the value ~emacs-version~ since it makes
it easier to upgrade or downgrade Emacs without any conflict with the already
installed packages. The default value is ~emacs-version~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-elpa-subdirectory 'emacs-version)
#+END_SRC
Spacemacs has a capacity of performing rollbacks after updates. We can set the
maximum number of rollback slots to keep in the cache. The default value is ~5~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-max-rollback-slots 5)
#+END_SRC
*** Elpa repository
:PROPERTIES:
:CUSTOM_ID: Init-Package_managment_and_updates-Elpa_repository-c07fb1c4
:END:
It is possible to ask Emacs to use an HTTPS connection when contacting the Elpa
whenever possible. This value should be set to ~nil~ when the user has no way to
contact the Elpa though HTTPS, otherwise it is strongly recommended to let it
set to ~t~. This variable however has no effect if Emacs is launched with the
parameter ~--insecure~ which forces the value of this variable to ~nil~. The
default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-elpa-https t)
#+END_SRC
We can set a maximum amount of seconds which will represent the maximum allowed
time to contact the Elpa repository. By default, this setting is set on ~5~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-elpa-timeout 5)
#+END_SRC
*** Spacelpa repository
:PROPERTIES:
:CUSTOM_ID: Init-Package_managment_and_updates-Spacelpa_repository-a431b288
:END:
The Spacelpa repository is a Spacemacs-specific package repository. It is
possible to use it as the primary source to install a locked version of a
package. If the below value is set to ~nil~, then Spacemacs will install the
latest version of packages from MELPA. I personally don’t use it, so I let it
set to ~nil~. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-use-spacelpa nil)
#+END_SRC
If the below value is not ~nil~, then the signature for the downloaded Spacelpa
packages must be verified.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-verify-spacelpa-archives t)
#+END_SRC
** Editing style
:PROPERTIES:
:CUSTOM_ID: Init-Editing_style-56d58a4b
:END:
By default, Spacemacs encourages the use of evil-mode, which brings vim
keybinding in Emacs. Still, it has three different styles available:
- ~vim~, which goes full evil-mode usage and most adapted to Emacs newcomers,
especially if they were used to vim before, with the use of a normal mode and
an insert mode.
- ~emacs~ which keeps an Emacs-like feel to the keybindings, without any
difference between an insert or normal mode.
- ~hybrid~ is a modification of the ~vim~ mode which brings the ~emacs~ style in
insert mode, but otherwise behaves like the ~vim~ style in normal mode. This
is the style I personally use.
The value can also be a list with the ~:variables~ keyword (similar to layers).
Check the editing styles section of the documentation for details on available
variables. The default value is ~vim~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-editing-style

hybrid-mode-default-state 'normal))
#+END_SRC
If non-nil, the paste transient-state is enabled. While enabled, after you paste
something, pressing ~C-j~ and ~C-k~ several times cycles through the elements in
the ~kill-ring~. Default ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-enable-paste-transient-state t)
#+END_SRC
** Spacemacs home configuration
:PROPERTIES:
:CUSTOM_ID: Init-Spacemacs_home_configuration-8375cdcc
:END:
The value below specifies the startup banner of Spacemacs. The default value is
~official~, it displays the official Spacemacs logo. An integer value is the
index of text banner, ~random~ chooses a random text banner in the
~core/banners~ directory. A string value must be a path to an image format
supported by your Emacs build. If the value is nil, then no banner is displayed.
The default value is ~official~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-startup-banner 'official)
#+END_SRC
On the Spacemacs homepage, a list of elements can also be shown, be it recent
files, projects, agenda items,… Each of the elements making up the list value of
the below variable are pairs in the form ~(list-type . list-size)~. If the value
is ~nil~, then it is disabled. The possible values for ~list-type~ are:
- ~recents~ :: displays recently opened files
- ~bookmarks~ :: displays saved bookmarks
- ~projects~ :: displays projectile projects recently opened
- ~agenda~ :: displays upcoming events from Org-mode agendas
- ~todos~ :: displays recent TODOs detected in projectile projects
The order in which they are set in the below list affects their order on the
Spacemacs startup page. List sikes may be ~nil~, in which case
~spacemacs-buffer-startup-lists-length~ takes effect.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-startup-lists '((recents . 15)
(projects . 15)))
#+END_SRC
The below variable allows the startup page to respond to resize events. Its
default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-startup-buffer-responsive t)
#+END_SRC
If non-nil show the version string in the Spacemacs buffer. It will appear as
~(spacemacs version)@(emacs version)~. Default ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-startup-buffer-show-version t)
#+END_SRC
** Default major modes
:PROPERTIES:
:CUSTOM_ID: Init-Default_major_modes-37f4a891
:END:
The below variable sets a default major mode for a new empty buffer. Possible
values are mode names such as ~text-mode~, or ~nil~ to use Fundamental mode. The
default value is ~text-mode~, but I prefer to use ~org-mode~ by default.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-new-empty-buffer-major-mode 'org-mode)
#+END_SRC
Similarly, the below variable sets the default mode for the scratch buffer. Its
default value is ~text-mode~, but I set it to use ~emacs-lisp-mode~ by default.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-scratch-mode 'emacs-lisp-mode)
#+END_SRC
By the way, it is possible to set a default message for the scratch buffer, such
as “Welcome to Spacemacs!”. I prefer to keep it clean. The default value is
~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-initial-scratch-message nil)
#+END_SRC
** Visual configuration

*** Themes
:PROPERTIES:
:CUSTOM_ID: Init-Visual_configuration-Themes-315992bb
:END:
Spacemacs makes it quite easy to use themes and organize them. The below value
is a list of themes, the first of the list is loaded when Spacemacs starts. The
user can press ~SPC T n~ to cycle to the next theme in the list.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-themes '(nord doom-nord doom-vibrant spacemacs-dark

kaolin-galaxy kaolin-mono-dark kaolin-temple
kaolin-valley-dark))
#+END_SRC
Emacs also makes use of themes for the Spaceline at the bottom of buffers.
Supported themes are:
- ~spacemacs~
- ~all-the-icons~
- ~custom~
- ~doom~ (the one I use)
- ~vim-powerline~
- ~vanilla~
The first three are Spaceline themes. ~doom~ is the Doom-Emacs mode-line, and
~vanilla~ is the default Emacs mode-line. ~custom~ is a user defined theme,
refer to Spacemacs’ ~DOCUMENTATION.org~ file for more info on how to create your
own Spaceline theme. Value can be a symbol or list with additional properties.
The default value is ~'(spacemacs :separator wave :separator-scale 1.5))~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-mode-line-theme '(doom
:separator wave
:separator-scale 1.0))
#+END_SRC
It is also possible to color the cursor depending on which mode Spacemacs is in,
in order to mach the state color in GUI Emacs. The default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-colorize-cursor-according-to-state t)
#+END_SRC
The below variable sets either the default font or a prioritized list of fonts
to be used by Emacs. The ~:size~ can be specified as a non-negative integer
(pixel size), or a floating-point (point size). Point size is recommended,
because it’s device independent (add a ~.0~ to make an integer a floating
point). The default size is ~10.0~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-default-font '("Cascadia Code"
:size 9.0))
#+END_SRC
I also added the following code in order to define a fallback font for emojis,
defined only on their unicode range:
#+BEGIN_SRC emacs-lisp
(set-fontset-font "fontset-default" '(#x1f600 . #x1f64f) "NotoEmoji Nerd Font")
#+END_SRC
*** Other on-screen elements
:PROPERTIES:
:CUSTOM_ID: Init-Visual_configuration-Other_on-screen_elements-7d334e09
:END:
~which-key~ is a helper which displays available keyboard shortcuts. This
variable sets in seconds the time Spacemacs should wait between a key press and
the moment ~which-key~ should be shown.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-which-key-delay 1)
#+END_SRC
This variable sets ~which-key~'s frame position. Possible values are:
- ~right~
- ~bottom~
- ~right-then-bottom~
~right-then-bottom~ tries to display the frame to the right, but if there is
insufficient space it displays it at the bottom. The default value is ~bottom~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-which-key-position 'right-then-bottom)
#+END_SRC
This controls where ~switch-to-buffer~ displays the buffer. If the value is
~nil~, ~switch-to-buffer~ displays the buffer in the current window even if
another same-purpose window is available. If non-nil, ~switch-to-buffer~
displays the buffer in a same-purpose window even if the buffer can be displayed
in the current window. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-switch-to-buffer-prefers-purpose nil)
#+END_SRC
If this variable is non-nil, a progress bar is displayed when Spacemacs is
loading. This may increase the boot time on some systems and emacs builds, set
it to ~nil~ to boost the loading time. The default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-loading-progress-bar t)
#+END_SRC
If the value is non-nil, Emacs will show the title of the transient states. The
default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-show-transient-state-title t)
#+END_SRC
If non-nil, this will show the color guide hint for transient state keys. The
default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-show-transient-state-color-guide t)
#+END_SRC
If non-nil, unicode symbols are displayed in the mode line. If you use Emacs as
a daemon and want unicode characters only in GUI set the value to quoted
~display-graphic-p~. The default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-mode-line-unicode-symbols t)
#+END_SRC
If non-nil, smooth scrolling (native-scrolling) is enabled. Smooth scrolling
overrides the default behavior of Emacs which recenters point when it reaches
the top or bottom of the screen. The default value is ~t~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-smooth-scrolling t)
#+END_SRC
The following value controls the line number activation. If set to ~t~,
~relative~ or ~visual~ then line numbers are enabled in all ~prog-mode~ and
~text-mode~ derivatives. If set to ~relative~, line numbers are relative. If set
to ~visual~, line numbers are also relative, but only visual lines are counted.
For example, folded lines will not be counted and wrapped lines are counted as
multiple lines. This variable can also be set to a property list for finer
control:
#+BEGIN_SRC emacs-lisp :tangle no
'(:relative nil
:visual nil
:disabled-for-modes dired-mode
doc-view-mode
markdown-mode
org-mode
pdf-view-mode

#+END_SRC
When used in a plist, ~visual~ takes precendence over ~relative~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-line-numbers '(:relative nil
:visual nil
:disabled-for-modes org-mode pdf-view-mode
dired-mode doc-view-mode
text-mode))
#+END_SRC
Select a scope to highlight delimiter. Possible values are:
- ~any~
- ~current~
- ~all~
- ~nil~
The default value is ~all~ (highlights any scope and emphasis the current one).
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-highlight-delimiters 'all)
#+END_SRC
After a certain amount of time in seconds, Spacemacs can zone-out. The default
value is ~nil~. I set it so Spacemacs zones out after 15 minutes.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-zone-out-when-idle 900)
#+END_SRC
Run ~spacemacs/prettify-org-buffer~ when visiting the ~README.org~ files of
Spacemacs. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-pretty-docs nil)
#+END_SRC
If ~nil~, the home buffer shows the full path of agenda items and todos. If non
~nil~, only the file name is shown.
#+BEGIN_SRC emacs-lisp

*** Appearance of Emacs frames
:PROPERTIES:
:CUSTOM_ID: Init-Visual_configuration-Appearance_of_Emacs_frames-59700bb7

Starting from Emacs 24.4, it is possible to make the Emacs frame fullscreen when
Emacs starts up if the variable is set to a non-nil value. The default value is
~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-fullscreen-at-startup nil)
#+END_SRC
This variable is to be used if the user does not want to use native fullscreen
with ~spacemacs/toggle-fullscreen~. This disables for instance the fullscreen
animation under OSX. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-fullscreen-use-non-native nil)
#+END_SRC
If you do not start Emacs in fullscreen at startup, you might want it to be
maximized by default. If the value for the variable below is set to be non-nil,
the frame will be maximized. This can only work if
~dotspacemacs-fullscreen-at-startup~ is set to ~nil~, and it is only available
from Emacs 24.4 onwards. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-maximized-at-startup nil)
#+END_SRC
If non-nil, the frame is undecorated when Emacs starts up. Combine this with the
variable ~dotspacemacs-maximized-at-startup~ in OSX to obtain borderless
fullscreen. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-undecorated-at-startup nil)
#+END_SRC
You can also set a transparency level for Emacs when you toggle the transparency
of the frame with ~toggle-transparency~. The value of the transparency, going
from 0 to 100 in increasing opacity, describes the transparency level of a frame
when it’s active or selected. The default value is ~90~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-active-transparency 85)
#+END_SRC
Similarly, you can set a value from 0 to 100 in increasing opacity which
describes the transparency level of a frame when it’s inactive or deselected.
The default value is ~90~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-inactive-transparency 80)
#+END_SRC
The variable below sets the format of frame title. You can use:
- ~%a~ :: the ~abbreviated-file-name~ or ~buffer-name~
- ~%t~ :: ~projectile-project-name~
- ~%I~ :: ~invocation-name~
- ~%S~ :: ~system-name~
- ~%U~ :: contents of ~$USER~
- ~%b~ :: buffer name
- ~%f~ :: visited file name
- ~%F~ :: frame name
- ~%s~ :: process status
- ~%p~ :: percent of buffer above top of window, or Top, Bot, or All
- ~%P~ :: percent of buffer above bottom of window, perhaps plus Top, or Bot, or
All
- ~%m~ :: mode name
- ~%n~ :: Narrow if appropriate
- ~%z~ :: mnemonics of buffer, terminal, and keyboard coding systems
- ~%Z~ :: like ~%z~, but including the end-of-line format
The default value is ~"%I@%S"~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-frame-title-format "Emacs: %b (%t) %U@%S")

#+END_SRC
** Spacemacs leader keys and shortcuts
:PROPERTIES:
:CUSTOM_ID: Init-Spacemacs_leader_keys_and_shortcuts-ebf21abe

The below setting sets the Spacemacs leader key. By default, this is the ~SPC~
key.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-leader-key "SPC")
#+END_SRC
Once the leader key has been pressed, it is possible to set another key in order
to call Emacs’ command ~M-x~. By default, it is again the ~SPC~ key.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-emacs-command-key "SPC")
#+END_SRC
It is also possible to invoke Vim Ex commands with the press of a key, and by
default it is the ~:~ key.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-ex-command-key ":")
#+END_SRC
The below variable sets the leader key accessible in ~emacs-state~ and
~insert-state~:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-emacs-leader-key "M-m")
#+END_SRC
The major mode leader key is a shortcut key which is the equivalent of pressing
~<leader> m~. Set it to ~nil~ to disable it. Its default value is ~,~.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-major-mode-leader-key ",")
#+END_SRC
In ~emacs-state~ and ~insert-state~, the same major mode leader key can be
accessible from another shortcut, which by default is ~C-M-m~ in terminal mode,
or ~M-return~ in GUI mode.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-major-mode-emacs-leader-key
(if window-system "<M-return>" "C-M-m"))
#+END_SRC
These variables control whether separate commands are bound in the GUI to the
key pairs ~C-i~ and ~TAB~, and ~C-m~ and ~RET~. Setting it to a non-nil value
allows for separate commands under ~C-i~ and ~TAB~, and ~C-m~ and ~RET~. In the
terminal, these pairs are generally indistinguishable, so this only works in the
GUI. The default value is ~nil~.
#+BEGIN_SRC emacs-lisp

#+END_SRC
** Layouts
:PROPERTIES:

** Files-related settings
:PROPERTIES:
:CUSTOM_ID: Init-Files-related_settings-67fba383

** Editing and modes
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-7dbaf258
:END:
There is first a setting I would like to enable to make the navigation through
text a bit easier which is to enable the subword mode. This allows me to iterate
through words that are in CamelCase more easily, I don’t have to go either to
the beginning or the end of the word and then move my cursor a bunch of times to
get to the subword I want to modify.
#+BEGIN_SRC emacs-lisp
(global-subword-mode 1)
#+END_SRC
*** Default modes
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-Default_modes-50d4e086
:END:
Some buffers sometimes won’t have a default mode at all, such as the ~*scratch*~
buffer. In any vanilla configuration, they will then default to ~text-mode~. I
personally prefer ~org-mode~ to be my default mode, so let’s set it so!
#+BEGIN_SRC emacs-lisp
(setq edit-server-default-major-mode 'org-mode)
#+END_SRC
*** Evil
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-Evil-3cedaaee
:END:
Evil is not really smart by default when I ask it to undo stuff. As an example,
let’s say I enter insert-mode and write a whole paragraph, and then I exit
insert-mode back to normal-mode, and I notice a small mistake I made when typing
my stuff down, like accidentally using a snippet from yasnippet, and I want to
undo that. My initial reaction would be to press ~u~ to undo, and so would be
yours too right? That’s the wrong answer with evil, since it considers your
actions between entering and leaving insert-mode as only one action, and it
would thus erase your /WHOLE PARAGRAPH/. Fortunately, there is a way to make the
undo action more granular, but it comes at the cost of increasing the amount of
undo actions you can do (which shouldn’t really matter if you don’t have a
potato PC).
#+BEGIN_SRC emacs-lisp
(setq undo-limit 500000
evil-want-fine-undo t)
#+END_SRC
*** File extensions
:PROPERTIES:
:CUSTOM_ID: User_Configuration-File_extensions-f76fe752
:END:
Sometimes, Emacs doesn’t recognize or misrecognizes some extensions, resulting
in a wrong mode set for said file. Let’s fix that by associating the extension
with the desired mode:
#+BEGIN_SRC emacs-lisp
(dolist (e '(("xml" . web-mode)
("xinp" . web-mode)
("aiml" . web-mode)
("C" . c++-mode)
("dconf" . conf-mode)
("yy" . bison-mode)
("ll" . flex-mode)
("s" . asm-mode)
("pl" . prolog-mode)
("l" . scheme-mode)
("vs" . glsl-mode)
("fs" . glsl-mode)))
(push (cons (concat "\\."
(car e)
"\\'") (cdr e))
auto-mode-alist))
#+END_SRC
We also have a couple of extensions which should all be in ~conf-unix-mode~,
let’s indicate that to Emacs:
#+BEGIN_SRC emacs-lisp
(dolist (e '("service" "timer" "target" "mount" "automount"
"slice" "socket" "path" "netdev" "network"
"link"))
(push (cons (concat "\\." e "\\'") 'conf-unix-mode)
auto-mode-alist))
#+END_SRC
*** Hooks
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Miscellaneous-Hooks-86da2da0
:END:
I also have some hooks I use for enabling some major and minor modes. The first
one here allows the execution of the deletion of trailing space each time I save
a file.
#+BEGIN_SRC emacs-lisp
(add-hook 'before-save-hook 'delete-trailing-whitespace)
#+END_SRC
I also want to always be in ~visual-line-mode~ so Emacs soft-wraps lines that
are too long for the buffer they are displayed in. This will also be enabled for
Elfeed.
#+BEGIN_SRC emacs-lisp
(add-hook 'prog-mode-hook 'visual-line-mode)
(add-hook 'elfeed-read-mode-hook 'visual-line-mode)
#+END_SRC
I also want for some non-programming modes to enable a hard-limit in terms of
how many characters can fit on one line. The modes that benefit are
~message-mode~, ~org-mode~, ~text-mode~ and ~markdown-mode~.
#+BEGIN_SRC emacs-lisp
(mapc (lambda (x)
(add-hook x 'visual-line-mode))
'(message-mode-hook
text-mode-hook
markdown-mode-hook))
#+END_SRC
*** Twittering mode
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Miscellaneous-Twittering_mode-b97d9327
:END:
For ~twittering-mode~, a Twitter major mode for Emacs, I want to encrypt my data
using a master password, which I do thanks to this option:
#+BEGIN_SRC emacs-lisp
(setq twittering-use-master-password t)
#+END_SRC
*** Wrapping regions
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-Wrapping_regions-2250281e
:END:
I really like the ~M-(~ keybinding for wrapping a selected region between
parenthesis. However, parenthesis are not everything (even in Lisp dialects),
and other wrappers could be nice. And they are! Here is how they are declared:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-[") 'insert-pair)
(global-set-key (kbd "M-{") 'insert-pair)
(global-set-key (kbd "M-<") 'insert-pair)
(global-set-key (kbd "M-'") 'insert-pair)
(global-set-key (kbd "M-`") 'insert-pair)
(global-set-key (kbd "M-\"") 'insert-pair)

** Emacs builtins

:CUSTOM_ID: User_Configuration-Emacs_builtins-7822b8dd
:END:
*** Dired
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Dired-ef8a7cac
:END:
When it comes to dired, I chose do modify some elements on how things are sorted
and shown, but there isn’t much configuration. First, I want to always copy
folders in a recursive way, no questions asked.
#+BEGIN_SRC emacs-lisp
(setq dired-recursive-copies 'always)
#+END_SRC
Also, when I have two Dired buffers opened side by side, I generally want them
to interact with each other, for example if I want to move around or copy stuff.
So, let’s tell Emacs that:
#+BEGIN_SRC emacs-lisp
(setq dired-dwim-target t)
#+END_SRC
Finally, let’s tell Dired how to sort the elements to be displayed: directories
first, non-hidden first.
#+BEGIN_SRC emacs-lisp
(setq dired-listing-switches "-ahl --group-directories-first")
#+END_SRC
By the way, let’s enable ~org-download~ when we are in a Dired buffer:
#+BEGIN_SRC emacs-lisp
(add-hook 'dired-mode-hook 'org-download-enable)
#+END_SRC
Finally, let’s enable globally ~diredfl~ so we can get a colourful Dired buffer
each time we open one:
#+BEGIN_SRC emacs-lisp
(diredfl-global-mode 1)
#+END_SRC
*** Emacs Lisp
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Emacs-builtins-Emacs-Lisp-219d4260
:END:
For some reason, =flycheck-mode= is not enabled by default when in an elisp
buffer. Let’s add that:
#+BEGIN_SRC emacs-lisp
(add-hook 'emacs-lisp-mode-hook 'flycheck-mode)
#+END_SRC
*** Eshell
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Eshell-3012e67e
:END:
Eshell is a built-in shell available from Emacs which I use almost as often as
Fish. Some adjustments are necessary for making this shell usable for me.
But first, here is a screenshot of what to expect visually from my configuration
of Eshell when it is launched:
#+include: ./img/eshell.svg export html
**** Aliases
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Eshell-Aliases-ef06615f
:END:
This function is a function that will come in very handy for Eshell functions
that call shell processes. It concatenates the initial string ~command~ with all
the arguments ~args~, each separated with a space.
#+BEGIN_SRC emacs-lisp
(defun phundrak/concatenate-shell-command ($command &rest $args)
(string-join (cons $command $args) " "))
#+END_SRC
Just like most shells, it is possible to declare in Eshell aliases. First, I
would like to be able to use ~open~ to open files in Emacs:
#+BEGIN_SRC emacs-lisp
(defalias 'open 'find-file)
#+END_SRC
I also have ~openo~ which allows me to perform the same action, but in another
window:
#+BEGIN_SRC emacs-lisp
(defalias 'openo 'find-file-other-window)
#+END_SRC
The function ~yes-or-no-p~ is also aliased to ~y-or-n-p~ so I only have to
answer by ~y~ or ~n~ instead of typing ~yes~ or ~no~.
#+BEGIN_SRC emacs-lisp
(defalias 'yes-or-no-p 'y-or-n-p)
#+END_SRC
For some ease of use, I’ll also declare ~list-buffers~ as an alias of ~ibuffer~.
#+BEGIN_SRC emacs-lisp
(defalias 'list-buffers 'ibuffer)
#+END_SRC
~mkcd~ is a function that allows me to create a directory and ~cd~ into it at
the same time.
#+begin_src emacs-lisp
(defun eshell/mkcd ($directory)
(eshell/mkdir "-p" $directory)
(cd $directory))
#+end_src
**** Custom functions
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Eshell-Custom_functions-79d98245
:END:
When I’m in Eshell, sometimes I wish to open multiple files at once in Emacs.
For this, when I have several arguments for ~find-file~, I want to be able to
open them all at once. Let’s modify ~find-file~ like so:
#+BEGIN_SRC emacs-lisp
(defadvice find-file (around find-files activate)
"Also find all files within a list of files. This even works recursively."
(if (listp filename)
(cl-loop for f in filename do (find-file f wildcards))
ad-do-it))
#+END_SRC
I also want to be able to have multiple instances of Eshell opened at once. For
that, I declared the function ~eshell-new~ that does exactly that.
#+BEGIN_SRC emacs-lisp
(defun eshell-new()
"Open a new instance of eshell."
(interactive)
(eshell 'N))
#+END_SRC
***** Redirect text editors to Emacs
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Eshell-Custom_functions-Redirect_text_editors_to_Emacs-dff362c6
:END:
I still have some stupid muscle memory telling me to open ~emacs~ in the
terminal, which is stupid with Eshell since I’m already inside Emacs. So, let’s
open each file passed to the ~emacs~ command and bury the eshell buffer (we’ll
get back to it later).
#+BEGIN_SRC emacs-lisp
(defun eshell/emacs (&rest $files)
"Open a file in a new buffer. Old habits die hard"
(if $files
(mapc #'find-file
(mapcar #'expand-file-name
(eshell-flatten-list (reverse $files))))
(bury-buffer)))
#+END_SRC
**** Environment variables
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Eshell-Environment_variables-8dac73e0
:END:
Some environment variables need to be correctly set so Eshell can correctly
work. The first environment variable to be set is the ~PATH~, as I have a couple
of directories where executables are located. Let’s add them to our path.
#+BEGIN_SRC emacs-lisp
(setenv "PATH"
(concat
(getenv "HOME") "/.pub-cache/bin"
":" (getenv "HOME") "/.local/bin"
":" (getenv "HOME") "/go/bin"
":" (getenv "HOME") "/.cargo/bin"
":" (getenv "HOME") "/.gem/ruby/2.6.0/bin"
":" (getenv "PATH")))
#+END_SRC
I would also like to set two environment variables related to Dart development:
the ~DART_SDK~ and ~ANDROID_HOME~ variables.
#+BEGIN_SRC emacs-lisp
(setenv "DART_SDK" "/opt/dart-sdk/bin")
(setenv "ANDROID_HOME" (concat (getenv "HOME") "/Android/Sdk/"))
#+END_SRC
Finally, I’d like to add a custom directory to the ~PKG_CONFIG_PATH~:
#+BEGIN_SRC emacs-lisp
(setenv "PKG_CONFIG_PATH" (concat
"/usr/local/lib/pkgconfig/" ":"
(getenv "PKG_CONFIG_PATH")))
#+END_SRC
The ~EDITOR~ variable also needs to be set for git commands, especially the
~yadm~ commands.
#+BEGIN_SRC emacs-lisp
(setenv "EDITOR" "emacsclient -c")
#+END_SRC
#+BEGIN_SRC emacs-lisp
(setenv "SHELL" "/bin/sh")
#+END_SRC
**** Eshell banner
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Emacs-builtins-Eshell-Eshell-banner-12d63d67
:END:
The code creating the Eshell banner is a bit lengthy and requires some
additional explanations that would make the following chapter [[#User_Configuration-Eshell-Eshell_theme-a06715a9][Eshell theme]] too
long. So, here it is!
The banner for Eshell will collect some system information and display them
gracefully. These pieces of information are:
- The GNU/Linux distribution running (I do not use any other OS on my computer)
- The kernel name and its version
- The machine’s hostname
- Its uptime
- Its RAM and Swap usage
- How full are its mountpoints
Some of these information can be grabbed directly from Emacs built-in functions,
but some others need to be retrieved manually. Let’s first get into it with the
mounted partitions for which we’ll define a structure:
#+BEGIN_SRC emacs-lisp
(cl-defstruct phundrak/mounted-partitions
"Object representing a mounted partition found in the system"
path size used percent)
#+END_SRC
We’ll also define a variable setting the maximum length of a partition path
before it gets abbreviated:
#+BEGIN_SRC emacs-lisp
(defvar phundrak//eshell-banner--max-length-part 13
"Maximum length of a partition path")
#+END_SRC
Now, we can get our partitions. For this, we’ll make a call to the shell command
~df -lH~ and we’ll keep only the partitions mounted on a device stored in
~/dev~, for instance on ~/dev/sda~. And as mentioned above, if the mount path of
the partition exceeds the length specified by
~phundrak//eshell-banner--max-length-part~, it will get abbreviated by
[[#User-Configuration-Custom-functions-macros-and-variables-phundrak-abbr-path-559b46e3][~phundrak-abbr-path~]].
#+BEGIN_SRC emacs-lisp
(defun phundrak/get-mounted-partitions ()
(let ((partitions (s-split "\n"
(shell-command-to-string "df -lH")
t)))
(-keep (lambda (partition)
(let* ((partition (s-split " " partition t))
(filesystem (nth 0 partition))
(size (nth 1 partition))
(used (nth 2 partition))
(percent (nth 4 partition))
(mount (nth 5 partition)))
(when (s-prefix? "/dev" filesystem)
(make-phundrak/mounted-partitions
:path (if (> phundrak//eshell-banner--max-length-part (length mount))
mount
(phundrak-abbr-path mount t))
:size size
:used used
:percent (string-to-number (s-chop-suffix "%" percent))))))
partitions)))
#+END_SRC
We’ll need some padding for the name of the information displayed on the left
hand side of the banner. The maximum length without any partitions is eight
characters due to the text ~Hostname~, so if any partition path is longer than
this, the left padding will increase.
#+BEGIN_SRC emacs-lisp
(defun phundrak//eshell-banner--get-left-pad (initial-pad partitions)
(if partitions
(let ((part-length (length (phundrak/mounted-partitions-path (car partitions)))))
(phundrak//eshell-banner--get-left-pad (if (> part-length initial-pad)
part-length
initial-pad)
(cdr partitions)))
initial-pad))
#+END_SRC
Now, Let’s set three variables that will be used in the function following this
declaration. They will be used to determine in which color a percentage should
be displayed. I’ll consider any percentage below 60% to be acceptable and
therefore displayed in green. However, starting from this threshold, I want the
user to be noticed of the usage of whatever percentage shown that it has gone up
and it should be watched and displayed in yellow. Above 75%, the user should
consider this a warning, and the percentage will be displayed in orange. Above
90%, it is considered critical and the percentage will be displayed in red.
#+BEGIN_SRC emacs-lisp
(defvar phundrak//eshell-banner--critical-percentage 90)
(defvar phundrak//eshell-banner--warning-percentage 75)
(defvar phundrak//eshell-banner--notice-percentage 60)
(defun phundrak//eshell-banner--color-percentage (percentage)
(cond
((> percentage phundrak//eshell-banner--critical-percentage)
(with-face (format "%2d" percentage) :foreground phundrak-nord11))
((> percentage phundrak//eshell-banner--warning-percentage)
(with-face (format "%2d" percentage) :foreground phundrak-nord12))
((> percentage phundrak//eshell-banner--notice-percentage)
(with-face (format "%2d" percentage) :foreground phundrak-nord13))
(t
(with-face (format "%2d" percentage) :foreground phundrak-nord14))))
#+END_SRC
This function will be used when displaying progress bars. These will be used for
displaying the Ram, Swap and partitions usage of the system, displaying the used
part in red and the free part in green. For this, we just need to know the size
of the progress bar we wish to use as well as how full it should be. Note that
the percentage should be between 0 and 100.
#+BEGIN_SRC emacs-lisp
(defun phundrak//eshell-banner--progress-bar (length percentage)
(let* ((length-green (if (= 0 percentage)
0
(/ (* length percentage) 100)))
(length-red (- length length-green)))
(concat (with-face "[" :weight 'bold)
(with-face (s-repeat length-green "=")
:weight 'bold :foreground phundrak-nord14)
(with-face (s-repeat length-red "=")
:weight 'bold :foreground phundrak-nord11)
(with-face "]" :weight 'bold))))
#+END_SRC
This function will be used in two distinct functions: ~phundrak-eshell-banner~
which we will see later, and ~phundrak//eshell-banner--display-memory~ which we
will see now. This function displays information for the two types of memory we
have, RAM and Swap memory. Here is the definition of this function:
#+BEGIN_SRC emacs-lisp
(defun phundrak//eshell-banner--display-memory (type used total text-padding ramp-length)
(let ((percentage (if (= used 0)
0
(/ (* 100 used) total))))
(concat (s-pad-right text-padding "." type)
": "
(phundrak//eshell-banner--progress-bar ramp-length
percentage)
(format " %6s / %-5s ("
(file-size-human-readable used)
(file-size-human-readable total))
(phundrak//eshell-banner--color-percentage
percentage)
"%)\n")))
#+END_SRC
We now need a function for displaying partitions. As you can see, it will be
quite similar to the above one:
#+BEGIN_SRC emacs-lisp
(defun phundrak//eshell-banner--display-partition (part left-pad ramp-length)
(concat (s-pad-right left-pad "."
(with-face (phundrak/mounted-partitions-path part)
:weight 'bold))
": "
(phundrak//eshell-banner--progress-bar ramp-length
(phundrak/mounted-partitions-percent part))
(format " %6s / %-5s (%s%%)"
(phundrak/mounted-partitions-used part)
(phundrak/mounted-partitions-size part)
(phundrak//eshell-banner--color-percentage (phundrak/mounted-partitions-percent part)))))
#+END_SRC
And we can now build our banner! Here is our function that does exactly that:
#+BEGIN_SRC emacs-lisp
(defun phundrak-eshell-banner ()
(let* ((partitions (phundrak/get-mounted-partitions))
(os (replace-regexp-in-string
".*\"\\(.+\\)\""
"\\1"
(car (-filter (lambda (line)
(s-contains? "PRETTY_NAME" line))
(s-lines (phundrak-file-to-string "/etc/os-release"))))))
(memory (-map (lambda (line)
(s-split " " line t))
(s-split "\n"
(shell-command-to-string "free -b | tail -2")
t)))
(ram (nth 0 memory))
(swap (nth 1 memory))
(ramp-length 41)
(left-pad (phundrak//eshell-banner--get-left-pad phundrak//eshell-banner--max-length-part partitions))
(right-pad 8)
(left-column-width 27))
(concat (format "%s\n" (s-repeat 79 "="))
;; OS and Kernel
(format "%s: %s%s: %s\n"
(s-pad-right left-pad "." "OS")
(s-pad-right left-column-width
" "
(with-face (s-trim os)
:weight 'bold))
(s-pad-right right-pad "." "Kernel")
(with-face (concat "Linux " operating-system-release)
:weight 'bold))
;; Hostname and Uptime
(format "%s: %s%s: %s\n"
(s-pad-right left-pad "." "Hostname")
(s-pad-right left-column-width
" "
(with-face (system-name) :weight 'bold))
(s-pad-right right-pad "." "Uptime")
(with-face (s-chop-prefix "up "
(s-trim (shell-command-to-string "uptime -p")))
:weight 'bold))
;; RAM ramp
(phundrak//eshell-banner--display-memory "Ram"
(string-to-number (nth 2 ram))
(string-to-number (nth 1 ram))
left-pad
ramp-length)
;; SWAP ramp
(phundrak//eshell-banner--display-memory "Swap"
(string-to-number (nth 2 swap))
(string-to-number (nth 1 swap))
left-pad
ramp-length)
;; Partitions
(mapconcat (lambda (part)
(phundrak//eshell-banner--display-partition part left-pad ramp-length))
partitions
"\n")
(format "\n%s\n" (s-repeat 79 "=")))))
#+END_SRC
We now only have to set the result of this function as our Eshell banner. Since
a simple ~setq~ would only run ~phundrak-eshell-banner~ once when Emacs starts,
we’ll actually make Emacs set the value of ~eshell-banner-message~ each time it
is required by Eshell with a hook:
#+BEGIN_SRC emacs-lisp
(add-hook 'eshell-banner-load-hook
(lambda ()
(setq eshell-banner-message (phundrak-eshell-banner))))
#+END_SRC

As with most shells, again, it is possible to customize the appearance of the
Eshell prompt. As you can see, my prompt has some Nord colors, a shortened path,
a git prompt, and an indicator of whether the previous command succeeded or
failed. Note however that the abbreviation of the current path depends on the
value of ~phundrak-prompt--abbreviate~, if it is ~t~ it is abbreviated;
otherwise, it is kept in full. It can be toggled with a keyboard shortcut, see

need it to be exported to, for agenda management, and for literary programming,
such as with this document.

:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_babel_languages-c062fc16
:END:
One of the amazing features of org-mode is its literary programming capacities
by running code blocks from within Org-mode itself. But for that, only a couple
of languages are supported directly by Org-mode itself, and they need to be
activated. Here are the languages I activated in my Org-mode configuration:
#+NAME: org-babel-languages-table
| C |
| dot |
| emacs-lisp |
| gnuplot |
| latex |
| latex-as-png |
| makefile |
| plantuml |

#+NAME: org-babel-languages-gen

#+header: :var languages=org-babel-languages-table[,0]
#+BEGIN_SRC emacs-lisp :exports none
(format "'(%s)"
(mapconcat (lambda ($language)
(format "(%s . t)" $language))
languages
"\n "))
#+END_SRC
#+RESULTS[71d98616bf4f1351ca93aea4972be0ba58057230]: org-babel-languages-gen
#+begin_example

(makefile . t)
(plantuml . t)
(python . t)
(restclient . t)
(sass . t)
(scheme . t)
(shell . t))
#+end_example
The corresponding code is as follows:
#+NAME: org-babel-load-languages
#+BEGIN_SRC emacs-lisp :noweb yes
(org-babel-do-load-languages
'org-babel-load-languages
<<org-babel-languages-gen()>>)
#+END_SRC
Scheme requires a default implementation for geiser:
#+NAME: org-babel-set-geiser
#+BEGIN_SRC emacs-lisp
(setq geiser-default-implementation 'racket)
#+END_SRC
By the way, I wish to see source code behave the same way in the source blocks
as in their own major mode. Let’s tell Emacs so:
#+NAME: org-src-tab-acts-natively
#+BEGIN_SRC emacs-lisp
(setq org-src-tab-acts-natively t)
#+END_SRC
Lastly, I know this can be a terrible idea, but I want Emacs to just evaluate
Org code blocks without asking me. Of course, this could represent some big
security issue if not careful enough, but I generaly just open my own org files.
#+NAME: org-confirm-babel

As I will always say, orgmode is an amazing piece of software that deserves
particular care and love. That is why I want to give it a unique look and feel
compared to the rest of my Emacs configuration, in order to make it feel much
more comfortable. You will find below how my org buffers look like when I open
one of them.

In order to make org-mode even sexier, let’s enable ~variable-pitch-mode~ for
org-mode so we can get some proportional font. I’ll also remove ~auto-fill-mode~

When it comes to source blocks in org-mode, Emacs handle them really well with
some beautiful syntax highlight thanks to the the languages’ major mode and
their font-locks. But inline src blocks are the forgotten child and get next to
no love, which is really sad ; I want it to feel loved, to stand out from the

Here is one behavior that I really want to see modified: the ability to use
~M-RET~ without slicing the text the marker is on.
#+NAME: org-M-RET-may-split-line
#+BEGIN_SRC emacs-lisp

#+END_SRC
Since Org 9.3, Org no longer attempts to restore the window configuration in the
frame to which the user returns after editing a source block with
~org-edit-src-code~. This means with the original value of
~org-src-window-setup~ (~reorganize-frame~), the current frame will be split in
two between the original org window and the source window, and once we quit the
source window only the org window will remain. This is not a desired behavior
for me, so I chose to set this variable to ~split-window-right~ in order to keep
my windows organization and have a similar behavior to the old one.
#+NAME: org-src-window-setup
#+BEGIN_SRC emacs-lisp
(setq org-src-window-setup 'split-window-below)
#+END_SRC
However, it is not rare that I want to change that for an horizontal split,
which can be achieved with the value ~split-window-below~. Thus, I have made
this function that allows me to switch between the (default) vertical split and
the horizontal split.
#+NAME: org-src-window-toggle
#+BEGIN_SRC emacs-lisp
(defun phundrak/toggle-org-src-window-split ()
"This function allows the user to toggle the behavior of

`split-window-right'"

The tag ~:noexport:~ is fine and all, but it doesn’t allow for hidden org
structures, that is headers that are visible in the org buffer but once the file
is exported to another format the header disappears but its content stays.
~ox-extra~ has such a feature through ~ignore-headlines~.
#+BEGIN_SRC emacs-lisp
(require 'ox-extra)
(ox-extras-activate '(ignore-headlines))
#+END_SRC
This gives us access to the ~:ignore:~ tag which allows the behavior above
mentioned. To give you an idea, the org buffer

With Spacemacs, an Org capture can be invoked with the shortcut ~SPC a o c~. It
will then ask which template I wish to use. In the table below are described the
shortcuts that are available after ~SPC a o c~ is invoked. The /name/ will be
the one displayed in Org capture’s interface, the /title/ is the headline where
to save the capture (if it does not differ from the capture’s name, the cell
will be blank). The /insertion mode/ tells Emacs how to add the capture to the
/file/, using which /template/. A line with no insertion mode, file, or template
is just a category. All of the following insert entries to their org files, that
is a new org node with a headline and some content.

#+END_SRC
You may notice a capture entry for my journal, and this is due to the fact I do
not use ~org-journal~ anymore: it was too overpowered for me, and I prefer to
keep it simple with a single file. And as you can see, and unlike a lot of other
Emacs configurations, the content of the template is not set in the variable,
but in external files which can be modified freely as actual Org buffers instead
of trying to get a proper one with loads of ~\n~ characters and such. All these
templates are declared below.
In the next sub-sections will be described my org capture templates. These are
not tangled into my Emacs configuration files, but into separate ~.orgcaptmpl~
files stored into =~/org/capture/=.
***** Emails
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Emails-d87336fe
:END:
This is my template for a new Email:
#+BEGIN_SRC org :tangle ~/org/capture/email.orgcaptmpl

Sent from a Free and Open-Source Linux operating system with GNU/Emacs
#+END_SRC
I use it in case my computer is not yet connected to the internet and I need to
already write the email so I can send it later. All I will need to to afterwards
will be to copy and paste my capture in a new message buffer and send it once I
am back online. This is exported to =~/org/capture/email.orgcaptmpl=.
***** Journal
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Journal-9916f9bf
:END:
This template is quite simple: it creates a new entry with the current timestamp
as its title, a brief title of my choosing, and then I can write whatever I wish
to write. This is exported to =~/org/capture/journal.orgcaptmpl=.
#+BEGIN_SRC org :tangle ~/org/capture/journal.orgcaptmpl
,* %U %^{Title}
%?
#+END_SRC
***** Notes
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Notes-4b4c10aa
:END:
This template is used for taking note about various subjects that can go from
conlanging to development. I wrote it so I can know from where this capture was
made and when, and it even supports text that was highlighted in Emacs that will
be inserted in a quote block. This is exported to
=~/org/capture/notes.orgcaptmpl=.
#+BEGIN_SRC org :tangle ~/org/capture/notes.orgcaptmpl
,* %^{Title}
:PROPERTIES:

:END:

#+END_SRC
***** Protocol
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Protocol-ec45ec49
:END:
This capture is used when received through org-protocol, with the Org-protocol
Extension for Firefox. It allows me to save in a quote block what I’ve
highlighted, as well as the link of the webpage on which my saved content was
highlighted. This file is exported to =~/org/capture/protocol.orgcaptmpl=.
#+BEGIN_SRC org :tangle ~/org/capture/protocol.orgcaptmpl

:PROPERTIES:
:CAPTURED: %U
:LINK: %:link

:END:
,#+begin_quote

,#+end_quote

#+END_SRC
This next capture template is used only when a link is sent to Emacs and no
content was highlighted.
#+BEGIN_SRC org :tangle ~/org/capture/protocol-link.orgcaptmpl
,* TODO [#C] Link: %^{Title}
:PROPERTIES:

***** Resources
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Resources-b23bfbd0
:END:
This is the default template for resources, which generally are located on the
Internet. By default, I give them the lowest priority, because although this is
something for me to remember later, it is not by default important. You can see
in the properties I record when the capture happened, and what the link is. The
title of the capture is a summary of what this is, while the body of the capture
is a more detailed explanation of what I capture, why, and how it could be
useful to me.

:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Tasks-Computers_and_stuff-a4eef8e3
:END:
One type of task I often capture is related to my servers or thing about
computers in general. With this, I can capture a task for which I will either
set a schedule or a deadline.
#+BEGIN_SRC org :tangle ~/org/capture/informatique.orgcaptmpl

****** Health
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-Tasks-Health-74f8f338

This capture is rarely used (I’m lucky to have a good health), but it can be
useful.
#+BEGIN_SRC org :tangle ~/org/capture/health.orgcaptmpl

be repeated yearly.

**** Custom org-mode functions
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Custom_org-mode_functions-f1726995
:END:
We begin with a couple of custom functions that I use in my org-mode files.
***** Custom and unique headings ID
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Custom_org-mode_functions-Custom_and_unique_headings_ID-44d2beaf
:END:
The first ones are dedicated to provide org-mode headings a fixed and unique ID
that won’t change over time. This code was taken from
[[https://writequit.org/articles/emacs-org-mode-generate-ids.html][https://writequit.org/articles/emacs-org-mode-generate-ids.html]]. The first
function’s job is to create these unique IDs
#+NAME: org-better-id-new
#+BEGIN_SRC emacs-lisp
(defun eos/org-id-new (&optional prefix)
"Create a new globally unique ID.
An ID consists of two parts separated by a colon:
- a prefix
- a unique part that will be created according to
`org-id-method'.
PREFIX can specify the prefix, the default is given by the
variable `org-id-prefix'. However, if PREFIX is the symbol
`none', don't use any prefix even if `org-id-prefix' specifies
one.
So a typical ID could look like \"Org-4nd91V40HI\"."
(let* ((prefix (if (eq prefix 'none)
""
(concat (or prefix org-id-prefix)
"-"))) unique)
(when (equal prefix "-")
(setq prefix ""))
(cond
((memq org-id-method
'(uuidgen uuid))
(setq unique (org-trim (shell-command-to-string org-id-uuid-program)))
(unless (org-uuidgen-p unique)
(setq unique (org-id-uuid))))
((eq org-id-method 'org)
(let* ((etime (org-reverse-string (org-id-time-to-b36)))
(postfix (when org-id-include-domain
(progn
(require 'message)
(concat "@"
(message-make-fqdn))))))
(setq unique (concat etime postfix))))
(t (error "Invalid `org-id-method'")))
(concat prefix (car (split-string unique "-")))))
#+END_SRC
Now, let’s see the function that will be used to get the custom id of a heading
at point. If the function does not detect any custom ID, then one should be
created and inserted.
#+NAME: org-better-id-get
#+BEGIN_SRC emacs-lisp
(defun eos/org-custom-id-get (&optional pom create prefix)
"Get the CUSTOM_ID property of the entry at point-or-marker POM.
If POM is nil, refer to the entry at point. If the entry does not
have an CUSTOM_ID, the function returns nil. However, when CREATE
is non nil, create a CUSTOM_ID if none is present already. PREFIX
will be passed through to `eos/org-id-new'. In any case, the
CUSTOM_ID of the entry is returned."
(interactive)
(org-with-point-at pom
(let* ((orgpath (mapconcat #'identity (org-get-outline-path) "-"))
(heading (replace-regexp-in-string
"[_-]+$" ""
(replace-regexp-in-string
"[-_]+" "-"
(replace-regexp-in-string
"[^a-zA-Z0-9-_]" "-"
(if (string= orgpath "")
(org-get-heading t t t t)
(concat orgpath "_" (org-get-heading t t t t)))))))
(id (org-entry-get nil "CUSTOM_ID")))
(cond
((and id
(stringp id)
(string-match "\\S-" id)) id)
(create (setq id (eos/org-id-new (concat prefix heading)))
(org-entry-put pom "CUSTOM_ID" id)
(org-id-add-location id
(buffer-file-name (buffer-base-buffer)))
id)))))
#+END_SRC
Finally, this is the function that gets called on file saves. If the function
detects ~auto-id:t~ among the org options in the ~#+OPTIONS:~ header, then the
above function is called.
#+NAME: org-better-id-add-ids
#+BEGIN_SRC emacs-lisp
(defun eos/org-add-ids-to-headlines-in-file ()
"Add CUSTOM_ID properties to all headlines in the current file
which do not already have one.
Only adds ids if the `auto-id' option is set to `t' in the file
somewhere. ie, #+OPTIONS: auto-id:t"
(interactive)
(save-excursion
(widen)
(goto-char (point-min))
(when (re-search-forward "^#\\+OPTIONS:.*auto-id:t" (point-max) t)
(org-map-entries (lambda () (eos/org-custom-id-get (point) 'create))))))
#+END_SRC
Let’s add a hook to the above function so it is called automatically on save,
and only in read-write functions.
#+NAME: org-better-id-hooks
#+BEGIN_SRC emacs-lisp
(add-hook 'org-mode-hook
(lambda ()
(add-hook 'before-save-hook
(lambda ()
(when (and (eq major-mode 'org-mode)

(eos/org-add-ids-to-headlines-in-file))))))
#+END_SRC
**** File export
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_files_exports-1e194169
:END:
I want to disable by default behavior of ~^~ and ~_~ for only one character,
making it compulsory to use instead ~^{}~ and ~_{}~ respectively. This is due to
my frequent usage of the underscore in my org files as a regular character and
not a markup one, especially when describing phonetics evolution. So, let’s
disable it:
#+NAME: org-use-sub-superscripts
#+BEGIN_SRC emacs-lisp
(setq org-use-sub-superscripts (quote {}))
#+END_SRC
***** LaTeX
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Emacs-builtins-Org-mode-File-export-LaTeX-92bbd6f3
:END:
When it comes to exports, I want the LaTeX and PDF exports to be done with
XeLaTeX only. This implies the modification of the following variable:
#+NAME: org-latex-compiler
#+BEGIN_SRC emacs-lisp
(setq org-latex-compiler "xelatex")
#+END_SRC
I also want to get by default ~minted~ for LaTeX listings so I can have syntax
highlights:
#+NAME: org-latex-listings
#+BEGIN_SRC emacs-lisp
(setq org-latex-listings 'minted)
#+END_SRC
The default packages break my LaTeX exports: for some reasons, images are not
loaded and exported in PDFs, so I needed to redifine the default packages
excluding the one that broke my exports. I also added two default packages,
~minted~ and ~xeCJK~ for syntax highlighting and Japanese (and additionally
Chinese and Korean) support.
#+NAME: org-latex-default-packages
#+BEGIN_SRC emacs-lisp
(setq org-latex-default-packages-alist '(("" "graphicx" t)
("T1" "fontspec" t ("pdflatex"))
("" "longtable" nil)
("" "wrapfig" nil)
("" "rotating" nil)
("normalem" "ulem" t)
("" "amsmath" t)
("" "textcomp" t)
("" "amssymb" t)
("" "capt-of" nil)
("" "minted" nil)

#+END_SRC
By the way, reference links in LaTeX should be written in this format:
#+NAME: org-export-latex-hyperref-format
#+BEGIN_SRC emacs-lisp
(setq org-export-latex-hyperref-format "\\ref{%s}")
#+END_SRC
When it comes to the export itself, the latex file needs to be processed several
times through XeLaTeX in order to get some references right. Don’t forget to
also run bibtex!
#+NAME: org-latex-pdf-process
#+BEGIN_SRC emacs-lisp
(setq org-latex-pdf-process
'("xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
"bibtex %b"
"xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"

#+NAME: org-re-reveal-root
#+BEGIN_SRC emacs-lisp

#+END_SRC
On HTML exports, Org-mode tries to include a validation link for the exported
HTML. Let’s disable that since I never use it.
#+NAME: org-html-validation
#+BEGIN_SRC emacs-lisp
(setq org-html-validation-link nil)
#+END_SRC
However, something I very often use are metadata information in my HTML files. I
just want to automate that. Fortunately, [[https://tecosaur.github.io/emacs-config/config.html#extra-header-content,code--3][Tecosaur comes to the rescue]]! First,
here is our function that will generate all the meta tags in our HTML:

This will use some special keywords in our org buffer and insert their content in

Another great features of Org-mode is the Org projects that allow the user to
easily publish a bunch of org files to a remote location. Here is the current
declaration of my projects, which will be detailed later:

***** Configuration website
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_projects-Configuration_website-79bd0468
:END:
This is my configuration for exporting my dotfiles to my website in a web format
only. No PDFs or anything, just HTML. Please note that I do not use that often
anymore, I much prefer the automatic script that I have which deploys through my
Drone instance my website on git pushes.
And before we get into the actual configuration, I would like to introduce a
couple of variables. This is a bit more verbose than if I declared everything
manually, but now I can change all three values at the same time without a
hasle.
#+NAME: org-proj-config-setup
#+BEGIN_SRC emacs-lisp

"Defines whether subdirectories should be parsed for config.phundrak.com")
#+END_SRC
Now, here is my configuration. In this snippet, my org files located in my
source directory get exported in the HTML format and published to my target
directory on my remote server through RSYNC via TRAMP. A sitemap is
automatically generated, which comes in handy with the online sitemap that is
available through the navigation bar.

*** Recentf
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Emacs-builtins-Recentf-b00d8ddd
:END:
~recentf-mode~ allows Emacs to list all recent files it read. It is also used by
Spacemacs to display a list of recent files so they can be quickly opened by the
user. Unfortunately, a lot of these files are just noise I don’t care about, but
fortunately we can ignore files with the variable ~recentf-exclude~. So, I will
ignore these paths:
#+name: recentf-ignored-paths
| =~/.authinfo.gpg= |

| =~/.emacs.d/= |

** EXWM

:CUSTOM_ID: User-Configuration-EXWM-12e1cca6
:END:
#+BEGIN_SRC emacs-lisp
(setq exwm-workspace-number 10)
#+END_SRC
** Keybindings
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-aef3f7a7
:END:
As you will see, I defined a LOT of custom keybindings. All of them are
Spacemacs keybindings, defined in a way they can be used seamlessly with Evil.
They almost all begin with ~o~, which is a prefix reserved for user-defined
keybindings so they won’t conflict with any package. Let’s declare it like so.
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "o" "custom")
#+END_SRC
Now, all keybindings that will be defined can be invoked in Normal-mode with the
~SPC~ key followed by the sequence assigned to each keybinding.
Before some more specialized categories, I have two commands which don’t fit
into any other category that I sometime use. The first one is a fix for the Bépo
keybindings which left out a keybind: ~winum-select-window-by-number~ is still
bound to ~SPC ²~, which is not a key that is available on the bépo layout
(instead, we use the dead key ~^~ followed by ~2~, or any digits). So instead,
let’s use the key that is physically in the same place: ~$~.
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "$" "select window by number")
(spacemacs/set-leader-keys "$" 'winum-select-window-by-number)
#+END_SRC
The following, I use it rarely, it can launch an external command from Emacs to
launch, for instance, my web browser or any other software not related to Emacs.
It offers a similar interface to [[https://wiki.archlinux.org/index.php/Dmenu][dmenu]] through helm.
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "or" "external command")
(spacemacs/set-leader-keys "or" 'helm-run-external-command)
#+END_SRC
However this one I use often, generally in org or text buffers.
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys "os" 'sort-lines)
#+END_SRC
*** Applications
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-Applications-af8730b1
:END:
As this is a new category, let’s declare its prefix:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "oa" "applications")
#+END_SRC
Now, let’s also declare the keybindings in this category. ~oac~ will invoke
Emacs’ calculator, while ~oac~ invokes the calendar, ~oae~ invokes the Eww web
browser, and ~oaw~ invokes the weather forecast. Lastly, the apostrophe in ~o'~
will invoke Eshell directly, without any popup window as with ~SPC '~ while
~oan~ will open a new eshell buffer if another one already exists. ~ov~ will
also open a vterm terminal.
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys
"o'" 'eshell-new
"ov" 'vterm
"oac" 'calc
"oaC" 'calendar
"oae" 'eww
"oaw" 'wttrin)
#+END_SRC
**** Image mode
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Keybindings-Applications-Image-mode-e5df694e
:END:
Viewing images in Emacs is nice, but I want to be able to do more than just view
them, such as opening them in GIMP. I’ll also declare a couple of keybindings
that make sense to me.
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix-for-mode 'image-mode "G" "Open in GIMP")
(spacemacs/declare-prefix-for-mode 'image-mode "o" "Open in external viewer")
(spacemacs/declare-prefix-for-mode 'image-mode "r" "Rotate clockwise")
(spacemacs/set-leader-keys-for-major-mode 'image-mode
"G" (lambda () (interactive) (start-process "" nil "gimp" (buffer-name)))
"o" (lambda () (interactive) (start-process "" nil "xdg-open" (buffer-name)))
"r" 'image-rotate)
#+END_SRC
**** Org tree slide
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Keybindings-Applications-Org_tree_slide-29545c5e
:END:
Finally, here we have the keybindings for ~org-tree-slide~, a presentation mode
with orgmode. Since I want the keys to be directly accessible without any prefix
from Spacemacs, I’ll have to declare them the vanilla way. First we have
keybindings that will launch the presentation:
#+BEGIN_SRC emacs-lisp
(define-key org-mode-map (kbd "<f8>") 'org-tree-slide-mode)
(define-key org-mode-map (kbd "s-<f8>") 'org-tree-slide-skip-done-toggle)
#+END_SRC
Next, we have some additional keybindings that will only be active when in
~org-tree-slide-mode~. The first one will allow us to exit this mode, while the
second one will toggle the display of headers marked as ~DONE~. Next, we have
~F9~ and ~F10~ which are bound to movement in the slide, while ~F11~ changes the
way the content is displayed. We also set ~org-tree-slide-skip-outline-level~ to
set the maximum depth we will display as an individual heading during the
presentation.
#+BEGIN_SRC emacs-lisp
(when (require 'org-tree-slide nil t)
(global-set-key (kbd "<f8>") 'org-tree-slide-mode)
(global-set-key (kbd "S-<f8>") 'org-tree-slide-skip-done-toggle)
(define-key org-tree-slide-mode-map (kbd "<f9>")
'org-tree-slide-move-previous-tree)
(define-key org-tree-slide-mode-map (kbd "<f10>")
'org-tree-slide-move-next-tree)
(define-key org-tree-slide-mode-map (kbd "<f11>")
'org-tree-slide-content)
(setq org-tree-slide-skip-outline-level 4)
(org-tree-slide-narrowing-control-profile)
(setq org-tree-slide-skip-done nil))
#+END_SRC
*** Comments
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-Comments-508db33d
:END:
Some keybindings are also related to comment editing, in particular using
outorg. Let’s first declare the dedicated prefix:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "oc" "comments")
#+END_SRC
Now, let’s declare the following keybindings:
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys
"occ" 'outorg-copy-edits-and-exit
"oce" 'outorg-edit-as-org
"oco" 'outline-minor-mode)
#+END_SRC
~oco~ enables the outline minor mode, which then allows for the edition of
comments in org buffers with ~oce~ and saving them to the original source file
with ~occ~.
*** Dired
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Keybindings-Dired-2a45af8d
:END:
A couple of keybindings will be added to Dired. The first one is the opening
parenthesis which will enable or disable ~dired-hide-details-mode~. On the other
hand, a closing parenthesis will show git information in the current Dired
buffer.
#+BEGIN_SRC emacs-lisp
(define-key dired-mode-map (kbd "(") 'dired-hide-details-mode)
(define-key dired-mode-map (kbd ")") 'dired-git-info-mode)
#+END_SRC
Something I use from time to time is ~S-F1~ for opening dired in my ~$HOME~
directory. For that, I simply did the following:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "<s-f1>") (lambda () (interactive) (dired "~/")))
#+END_SRC
A couple of other useful utilities, sach as opening all marked files, sorting
files, opening them externally and renaming them, are also bound to a simple key
press:
#+BEGIN_SRC emacs-lisp
(define-key dired-mode-map (kbd "f") 'phundrak-open-marked-files)
(define-key dired-mode-map (kbd "F") 'xah/open-in-external-app)
(define-key dired-mode-map (kbd "s") 'xah/dired-sort)
#+END_SRC
*** Files
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-Files-206c2126
:END:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "of" "open org file")
(spacemacs/set-leader-keys "of" 'phundrak-find-org-files)
#+END_SRC
I also have a shortcut for ~helm-locate~ in case I need to find a file that is
not in these directories. One advantage of this over ~helm-find~ is that it
doesn’t matter from where I call it, it will find any file on my system that
matches the query, whereas ~helm-find~ will only search in the current directory
and its subdirectories. This time, the declaration is much simpler:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "oF" "locate file")
(spacemacs/set-leader-keys "oF" 'helm-locate)
#+END_SRC
And that’s it! This should list all my org files under these directories and
give me fuzzy finding for these files. I just need to partially type the name of
the file I want to open and it should open without any issue.
*** Games
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Keybindings-Games-c9e6ac80
:END:
Just to make it easier to launch it, I’ll declare a shortcut for launching
tetris (which is built into Emacs).
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "oat" "tetris")
(spacemacs/set-leader-keys "oat" 'tetris)
#+END_SRC
Apparently, no evil keybindings are set for Tetris. Let’s declare them (adapted
to the bépo layout):
#+BEGIN_SRC emacs-lisp
(require 'tetris)
(define-key tetris-mode-map (kbd "c") 'tetris-move-left)
(define-key tetris-mode-map (kbd "t") 'tetris-move-down)
(define-key tetris-mode-map (kbd "s") 'tetris-rotate-prev)
(define-key tetris-mode-map (kbd "r") 'tetris-move-right)
#+END_SRC
*** Multiple cursors
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-Multiple_cursors-83db7c9c
:END:
I don’t really like Spacemacs’ layer for MultipleCursors, so I prefer to simply
install the package and create shortcuts for it myself. Let’s first declare
category:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "om" "multiple-cursors")
#+END_SRC
Now, let’s declare the shortcuts related to multiple-cursors:
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys
"ome" 'mc/edit-lines
"omn" 'mc/mark-next-like-this
"omp" 'mc/mark-previous-like-this
"oma" 'mc/mark-all-like-this)
#+END_SRC
*** Org-mode
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-Org-mode-a8938199
:END:
Now, onto some shortcuts related to org-mode. Let’s first declare the category:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix-for-mode 'org-mode "mo" "custom" "User-defined keybindings")
(spacemacs/declare-prefix-for-mode 'org-mode "mot" "toggle" "Toggle org elements")
(spacemacs/declare-prefix-for-mode 'org-mode "moT" "tables")
#+END_SRC
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys-for-major-mode 'org-mode "ob" 'phundrak-blog-publish)
(spacemacs/declare-prefix-for-mode 'org-mode "ob" "publish blog")
#+END_SRC
Now, I have a couple of shortcuts I use regularly:
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys-for-major-mode 'org-mode
"os" 'org-insert-structure-template
"ots" 'phundrak/toggle-org-src-window-split
"ott" 'org-sidebar-tree)
(spacemacs/declare-prefix-for-mode 'org-mode "moS" "insert template")
(spacemacs/declare-prefix-for-mode 'org-mode "mots" "toggle src split")
#+END_SRC
~os~ allows me to insert an org structure template defined in
~org-structure-template-alist~ (see [[#User_Configuration-Org-mode-Org_variables-Org_behavior-0319db38][Org behavior]]), while ~ott~ displays the
outline of the current org file.
~oT~ is the prefix for tree-related operations:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix-for-mode 'org-mode "moT" "tables")
#+END_SRC
These shortcuts allow to manipulate the width of the column the cursor is
currently in, by either shrinking it, expanding it, or toggling its state
between shrunk or expanded. A prefix for all of these commands has been also
added in order to make the purpose of the shortcuts clearer.
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys-for-major-mode 'org-mode
"oTt" 'org-table-toggle-column-width
"oTe" 'org-table-expand
"oTs" 'org-table-shrink)
(spacemacs/declare-prefix-for-mode 'org-mode "moTt" "toggle width")
(spacemacs/declare-prefix-for-mode 'org-mode "moTe" "expand")
(spacemacs/declare-prefix-for-mode 'org-mode "moTs" "shrink")
#+END_SRC
Finaly, I set the following shortcut in order to easily remove ~RESULTS~ blocks
from org source code blocks:
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys-for-major-mode 'org-mode
"or" 'org-babel-remove-result-one-or-many)
(spacemacs/declare-prefix-for-mode 'org-mode "mor" "remove org result")
#+END_SRC
*** Toggle
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Shortcuts-Toggle-d53c27ef
:END:
This category allows to toggle some modes and options.
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "ot" "toggle")
#+END_SRC
As you can see, I have here four shortcuts for toggling various elements in
Emacs:
- ~otb~ :: toggles ~fancy-battery-mode~. This comes in very handy when I am on a
laptop that is not pluged in or which is charging.
- ~otd~ :: toggles ~elcord-mode~. This mode is used to create an Emacs rich
integration in Discord.
- ~otf~ :: toggles the activation of FlyCheck, Emacs’ spell checker. It is by
default disabled, and I can turn it on with this shortcut only when needed.
- ~ots~ :: toggles ~prettify-symbols-mode~. This allows Emacs to replace some
symbols by some others, like for example by replacing ~lambda~ in Emacs Lisp
buffers with an actual λ.
- ~otS~ :: toggles whether or not Eshell should shorten the current path in its
prompt
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys
"otb" 'fancy-battery-mode
"otd" 'elcord-mode
"otf" 'flycheck-mode
"ots" 'prettify-symbols-mode
"otS" 'phundrak-prompt-toggle-abbreviation)
#+END_SRC
We also have some input methods-related shortcuts in a sub-category: ~oti~. The
first shortcuts below are used to either toggle between no input method or the
last one used (~otit~), or choose an input method among the various available
ones from Emacs (~otis~).
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "oti" "input methods")
(spacemacs/set-leader-keys
"otit" 'toggle-input-method
"otis" 'set-input-method)
#+END_SRC
The shortcuts below though allow me to directly switch to one of these three
known input methods I sometimes or often use, namely Japanese, Tibetan and IPA
(by typing in X-SAMPA).
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "otij" "Japanese")
(spacemacs/declare-prefix "otix" "IPA (X-SAMPA)")
(spacemacs/declare-prefix "otiT" "Tibetan")
(spacemacs/set-leader-keys
"otij" (lambda () (interactive) (set-input-method 'japanese))
"otix" (lambda () (interactive) (set-input-method 'ipa-x-sampa))
"otiT" (lambda () (interactive) (set-input-method 'tibetan-wylie)))
#+END_SRC
** Mu4e
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Mu4e-f3df8e9e
:END:
Mu4e is a frontend for mu, an email analyzer which sits on top of a Maildir
which gets updated with the ~mbsync~ command from ~isync~. It has a lot of neat
features, but I guess my favorite ones are:
1. the search query feature
2. rendering an HTML email in the browser
*** Setup
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Mu4e-Setup-1d23809e
:END:
Due to mu sitting on top of a maildir, I need to tell mu4e where said maildir
is, and point it the trash, archive, and sent folders as well as the refresh
command and how frequently I want my emails to be refreshed.
#+BEGIN_SRC emacs-lisp
(setq mu4e-maildir "~/.mail"
mu4e-trash-folder "/Trash"
mu4e-refile-folder "/Archive"
mu4e-sent-folder "/Sent"
mu4e-drafts-folder "/Drafts"
mu4e-get-mail-command "mbsync -a"
mu4e-update-interval 60)
#+END_SRC
This source block is an example of the search queries in mu4e, and part of the
reason why I very much like mu4e: these bookmarks are actually defined by search
queries, but act as if they were just yet another type of custom inbox you get
with modern Email client (and often you don’t even get them). All these
bookmarks can be accessed through a shortcut on the main mu4e buffer, prefixed

On new email arrival, Emacs can send the system a notification which will be
handled as any other notification received by the system and will display the
number of unread emails to the user; in my case, notifications are handled by
AwesomeWM.

This is the setup I have for my SMTP mail server: I point Emacs’ SMTP services
to my private mail server on its SMTP port, which should be used with a STARTTLS

I wish my emails to be signed by default using PGP/MIME. ~mu4e~ uses ~message~

Now this hook is added so I can get a maximal width for the text of my emails, I
really don’t like it when lines are kilometers long. I would like instead to

However, the package is currently broken (it was last updated in 2017): wttr.in
now returns by default an HTML page instead of an ASCII result. In order to fix
it, a ~?A~ must be added at the end of the request in order to get a nice

This is why I enable first the ~lsp-treemacs-sync-mode~ so treemacs is LSP
aware:
#+BEGIN_SRC emacs-lisp

#+END_SRC
I also enable some layers related to ~dap~, the Debug Adapter Protocol, which

**** Enable ~eldoc-mode~ by default
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Emacs_Lisp-Enable_~eldoc-mode~_by_default-f131abde
:END:
By default, if some Elisp code is opened, I want to enable ~eldoc-mode~ so I can

:CUSTOM_ID: User_Configuration-Emacs_Lisp-~phundrak-write-to-buffer~-2f192dd3
:END:
I was very surprised when I discovered no such function exists in Elisp. This
function basically writes a string into a buffer, and optionally switches the
user to the buffer. Here is the code for that function:
#+BEGIN_SRC elisp :results silent
(defun write-to-buffer ($input-string $outputbuf &optional $switchbuf)
"Writes `$input-string' to the specified `output-buffer'. If
`switch-buffer' is non-nil, the active buffer will switch to the
output buffer; otherwise, it will take the user back to their
initial buffer. Works with `$input-string' as a string or a list
of strings."
(let ((oldbuf (current-buffer)))
(switch-to-buffer $outputbuf)
(cond ((char-or-string-p $input-string) (insert $input-string))
((listp $input-string) (dolist (elem $input-string)

Emacs throws me an error about the python interpreter, let’s silence it:
#+BEGIN_SRC emacs-lisp

#+END_SRC
*** Rust
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Rust-ba633575
:END:
I need to point to racer where the source code of Rust is located so I can get
some documentation. This is installed with the ~rust-src~ component you can get
through ~rustup~. To install it, simply run
#+BEGIN_SRC sh :tangle no :exports code
rustup component add rust-src
#+END_SRC
Now, the source code for Rust should be included in your installation. I
personally prefer to develop with Rust stable, so let’s indicate to Emacs to
search for documentation in the stable sources:
#+BEGIN_SRC emacs-lisp
(setq racer-rust-src-path
"~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src")
#+END_SRC
Rust’s default ~cargo check~ command is already very good, however I also enjoy
getting some more hints while developping, and ~clippy~ does a very good job at
it. To get clippy, I need to run the following to install it:
#+BEGIN_SRC sh :tangle no :exports code
rustup compontent add clippy
#+END_SRC
And this will get it installed with all of my Rust toolchain, and it will be
updated with it. Now, let’s indicate LSP that I want to use that instead of
~check~:
#+BEGIN_SRC emacs-lisp
(setq lsp-rust-analyzer-cargo-watch-command "clippy")
#+END_SRC
Finally, I wish to enable ~electric-pair-mode~ and ~indent-guide-mode~ for Rust
files, so let’s enable that through the use of a hook:
#+BEGIN_SRC emacs-lisp :tangle no
(add-hook 'rust-mode-hook

(local-set-key (kbd "TAB") #'company-indent-or-complete-common)
(electric-pair-mode 1)))
#+END_SRC
*** Scheme
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Scheme-e35aa50a

The Scheme configuration will be very short, I just need to tell Emacs the name
of the interpreter since it is not the default one:
#+BEGIN_SRC emacs-lisp

#+END_SRC
** Projectile
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Projectile-06e580f0
:END:
Projectile is an awesome utility which helps managing projects within Emacs. It
will automatically detect version controlled directories, and will by default
assume this is a project I can be working on. However, there are some
directories that are version controlled that I do not want to see in my list of
projects, namely all the cached AUR packages from my AUR helper, ~paru~. They
are all stored in the same parent directory, so let’s ignore that. I will also
make Emacs ignore all ~node_modules~ directories it could encounter. And for
some reason, =~/.emacs.spacemacs= is always in my projects list (I now use
XDG-compliant directories), so let’s also ignore that.
#+BEGIN_SRC emacs-lisp
(setq projectile-ignored-projects '("~/.cache/paru" "~/.emacs.spacemacs" "/tmp"))

#+END_SRC
** Readers
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Readers-aacb14d4
:END:
Thanks to Discord user shanks, I discovered pdf-tools gives us access to a very
interesting minor mode: ~pdf-view-midnight-minor-mode~. And this is exactly what
I missed in my Emacs PDF reader from Zathura! I still think Zathura is a
fantastic tool, but now my PDF reader in Emacs is almost perfect! I just need to
adjust some colors:
#+BEGIN_SRC emacs-lisp
(with-eval-after-load 'pdf-view
(setq pdf-view-midnight-colors '("#d8dee9" . "#2e3440")))
#+END_SRC
Let’s also enable dark mode automatically:
#+BEGIN_SRC emacs-lisp
(add-hook 'pdf-tools-enabled-hook 'pdf-view-midnight-minor-mode)
#+END_SRC
And there we go! A beautiful, dark-mode PDF reader inside Emacs! And with
Spacemacs, I can enable or disable this minor mode anytime with the shortcut
~, n~.
** Security
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Security-21d88555
:END:
This paragraph is about making Emacs and GPG as a whole (since Emacs is /always/
open on my computer) more secure. The first thing I want to make is a function
that will close any buffer that contains an open ~.gpg~ file –I certainly do not
want anyone to be able to read such files on my computer if I leave it even for
a couple of minutes.
#+BEGIN_SRC emacs-lisp
(defun phundrak/kill-gpg-buffers ()
"Kill GPG buffers."
(interactive)
(let ((buffers-killed 0))
(dolist (buffer (buffer-list))
(with-current-buffer buffer
(when (string-match ".*\.gpg$" (buffer-name buffer))
(message "Auto killing .gpg buffer '%s'" (buffer-name buffer))
(when (buffer-modified-p buffer)
(save-buffer))
(kill-buffer buffer)
(setq buffers-killed (+ buffers-killed 1)))))
(unless (zerop buffers-killed)
;; Kill gpg-agent.
(shell-command "gpgconf --kill gpg-agent")
(message "%s .gpg buffers have been autosaved and killed" buffers-killed))))
#+END_SRC
Notice the ~(shell-command "gpgconf --kill gpg-agent")~ command there: it kills
~gpg-agent~ which will always respawn each time GPG2 is invoked. That way, I
know anyone trying to open a GPG file will have to insert my password when
trying to do so instead of just hoping I entered it not long ago and they won’t
have to.
But surely, if I only define this function and hope to call it each time I leav
my computer, surely at one point I will forget to execute it before leaving. I
can’t trust myself to always call it manually. Which is why I’ll ask Emacs
itself to call it after it detects a minute of idling. It may become from times
to times a bit of a pain, but at least I’m now sure I won’t ever have to worry
about someone reading my GPG files open in Emacs while I’m out for a quick
break.

Yasnippet’s snippets tool is extremely powerful and allows me to write very
quickly code. For now, we have snippets for two modes. The files you’ll see
below are exported to ~$HOME/.emacs.spacemacs/private/snippets/~ and to their
respective mode directory. For instance, my ~caption~ snippet for org-mode will
be exported to ~$HOME/.emacs.spacemacs/private/snippets/org-mode/caption~.
Be aware that on top of these custom snippets, I also use the package
[[file:awesome.org::#Autostart-f2cf42fe][yasnippet-snippets]] which provide plenty of already made snippets.
*** Rust snippets
:PROPERTIES:

#+BEGIN_SRC snippet :tangle ~/.emacs.spacemacs/private/snippets/rust-mode/println
# -*- mode: snippet -*-
# name: println
# key: pln

The second one is more interesting: it is used to create a ~new~ method for a
struct, and it will try to create a function that will assign each argument
passed to the method to members of the struct. It relies on the custom function
[[#Custom-functions-yas-rust-new-assignments-4ad16bde][I wrote here]].
#+BEGIN_SRC snippet :tangle ~/.emacs.spacemacs/private/snippets/rust-mode/new

The first two snippets are used to add HTML or LaTeX attributes to elements in
org-mode. The third also has a similar usage, inserting a ~#+CAPTION~ header

Now, the following is a bit more complex: it is meant to be used as a new org
buffer is created. It will insert an org header for the title, which will
default to the buffer’s name capitalized minus the dashes or underscores
replaced with spaces, it will insert a default author and email based on the
user’s parameters, and the date at the moment of the creation of these headers.
The user can also add some tags if they wish to.

Finally, there are a couple of miscellaneous org snippets that insert macros I
often use in my conlanging documents. The first one inserts a phonetics macro,
while the second one inserts a macro used for my Proto-Ñyqy language.

*** Docker
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Tramp_configuration-Docker-31573fdf
:END:
It is completely possible with Tramp to connect ot a docker container and modify
files inside of it. It is not supported natively, but we can add it quite
easily. Be aware, I am not the author of this code, you can find its original
source [[https://www.emacswiki.org/emacs/TrampAndDocker][here]]. First, let’s add the Docker protocol to Tramp:
#+BEGIN_SRC emacs-lisp
(push
(cons
"docker"
'((tramp-login-program "docker")
(tramp-login-args (("exec" "-it") ("%h") ("/bin/bash")))
(tramp-remote-shell "/bin/sh")
(tramp-remote-shell-args ("-i") ("-c"))))
tramp-methods)
#+END_SRC
Now that the method has been added, let’s add some autocompletion for when we
want to connect to a Docker container:
#+BEGIN_SRC emacs-lisp
(defadvice tramp-completion-handle-file-name-all-completions
(around dotemacs-completion-docker activate)
"(tramp-completion-handle-file-name-all-completions \"\" \"/docker:\" returns
a list of active Docker container names, followed by colons."
(if (equal (ad-get-arg 1) "/docker:")
(let* ((dockernames-raw (shell-command-to-string "docker ps --format '{{.Names}}:'"))
(dockernames (cl-remove-if-not #'(lambda (dockerline)
(string-match ":$" dockerline))
(split-string dockernames-raw "\n"))))
(setq ad-return-value dockernames))
ad-do-it))
#+END_SRC
And that’s it! it is now possible to connect to a docker container with
something like ~/docker:conlangdict_server/~ as the path given in ~find-file~.
*** Yadm
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Yadm-4344fec3
:END:
~yadm~ is the utility I use for managing my dotfiles, and it is a wrapper In
order to manage my dotfiles, I use the following shortcut to launch Magit Status
for ~yadm~:
#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "oy" "yadm status")
(spacemacs/set-leader-keys "oy" (lambda () (interactive) (magit-status "/yadm::")))
#+END_SRC
~yadm~ wraps around ~git~. Logically, it means Magit could theoretically manage
my yadm repo. And it is indeed possible, according to [[https://github.com/TheLocehiliosan/yadm/blob/master/yadm.md][this page]] using TRAMP. I
just need to add the following code snippet:
#+BEGIN_SRC emacs-lisp
(add-to-list 'tramp-methods
'("yadm"
(tramp-login-program "yadm")
(tramp-login-args (("enter")))
(tramp-login-env (("SHELL")
("/bin/sh")))
(tramp-remote-shell "/bin/sh")
(tramp-remote-shell-args ("-c"))))

Sometimes, some visual properties just don’t fit right for me and I need to edit
them. This is the case for example for org-mode for which I want to have a mix
of fixed and variable pitches. Below you can see the code that does that for me,
I’ll get into more detail below this code block.
#+BEGIN_SRC emacs-lisp :noweb yes
(let (
<<face-generate(input=org-common-faces, makeface="no")>>
)
(custom-theme-set-faces

<<face-generate(input=diff-faces)>>
<<face-generate(input=mu4e-faces)>>

**** Diff and Magit
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Visual-configuration-Better-faces-Diff-6ac98986
:END:
Apparently, diff and Magit faces do not follow the nord theme’s color scheme, so
let’s redefine their background and sometimes their foreground.
#+tblname: diff-faces

**** Mu4e
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Visual-configuration-Better-faces-Mu4e-7b52d940
:END:
The nord theme is great and all, but for some reason some faces in mu4e aren’t
displayed properly, such as the ~mu4e-highlight-face~. Let’s fix that!
#+tblname: mu4e-faces
| / | | |

Fonts will play an important part in this, but so will colors and font size. The
following code is largely based on the one found [[https://zzamboni.org/post/beautifying-org-mode-in-emacs/][on this blog post]] and [[https://lepisma.xyz/2017/10/28/ricing-org-mode/][this one]].

*** Info colors

*** Prettified symbols
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Miscellaneous-Prettified_symbols-da50f4a6

Just because it is pleasing to the eye, some symbols in source code get
prettified into simpler symbols. Here is the list of symbols that are to be
prettified. You can see in the corresponding comment what symbol will be
displayed.
#+BEGIN_SRC emacs-lisp
(setq prettify-symbols-alist '(("lambda" . 955) ; λ
("mapc" . 8614) ; ↦
("map" . 8614) ; ↦

#+END_SRC
*** Misc

Emacs is already silent, but let’s set the bell as visible:
#+BEGIN_SRC emacs-lisp
(setq visible-bell t)
#+END_SRC
I would also like to disable the global ~hl-mode~, I find it quite annoying.
#+BEGIN_SRC emacs-lisp
(global-hl-line-mode -1)
