* Introduction
:PROPERTIES:
:CUSTOM_ID: Introduction-f1cbb8bb
: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:
:header-args:emacs-lisp: :mkdirp yes :tangle ~/.config/emacs/private/spacemacs-layers.el :exports code :results silent
:CUSTOM_ID: Spacemacs_layers_and_packages-6d318b87
:END:
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 'unused)
#+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 none:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layer-path '())
#+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 you need some configuration for these packages, then consider creating a
layer. You 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-du | alternative to ~ncdu~ with Dired |
| doom-themes | some cool themes |
| edit-indirect | edit region in separate buffer |
| elcord | rich integration of Emacs in Discord |
| kaolin-themes | some cool themes |
| lsp-dart | apparently, it isn’t included in the Dart layer |
| magit-gitflow | integrate gitflow in Magit |
| multiple-cursors | I don’t like the layer, I prefer this package alone |
| 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 |
| pinentry | enter a GPG password from Emacs |
| s | The long lost Emacs string manipulation library. |
| 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-packages
#+BEGIN_SRC emacs-lisp :tangle no :var packages=extra-packages[,0] :exports none
(mapcar 'make-symbol packages)
#+END_SRC
#+BEGIN_SRC emacs-lisp :noweb yes :exports none
(setq-default dotspacemacs-additional-packages (quote <<make-extra-packages()>>))
#+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
spell-checking-enable-auto-dictionary t)
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

*** 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

*** 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

#+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

#+END_SRC
*** Internationalization
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Internationalization-69601ff8
:END:
In this category, I enabled the ~keyboard-layout~ layer to enable
compatibility with the bépo layout. This layer, however, is disabled for
magit, Dired and eww.
#+BEGIN_SRC emacs-lisp

**** 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
web-fmt-tool 'web-beautify
css-enable-lsp t
less-enable-lsp t
scss-enable-lsp t

#+END_SRC
The ~json~ layer is also enabled, with the format tool set to ~web-beautify~.
#+BEGIN_SRC emacs-lisp
(json :variables
json-fmt-tool 'web-beautify)
#+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
The Markdown layer has been enabled, with support for live preview with ~vmd~, and and automatic MMM-mode generation for C, C++, Python, Rust and
Emacs Lisp.
#+BEGIN_SRC emacs-lisp
(markdown :variables

**** Frameworks
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Programming_languages-Frameworks-f7c21585

Only one framework support has been enabled so far, and is is for the
Django framework.
#+BEGIN_SRC emacs-lisp

#+END_SRC
**** 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
c-c++-default-mode-for-headers 'c-mode

#+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
javascript-repl 'skewer

#+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
typescript-backend 'lsp)
#+END_SRC
I am also currently using the Awesome window manager which requires the Lua
programming language, so here it is.

**** Epub and Pdf readers
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Readers-Epub_and_Pdf_readers-0ef6688f
:END:
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

#+END_SRC
**** Elfeed
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Readers-Elfeed-78877179

Elfeed is an Emacs feeed and RSS reader which can be managed through org
files. Actually, through only one file in my case, located in my =~/org=

Only the ~git~ layer is enabled in this category.
#+BEGIN_SRC emacs-lisp

#+END_SRC
*** Themes
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Themes-d88d1225
:END:
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, Helpful, and LSP
layers enabled.
#+BEGIN_SRC emacs-lisp
dap docker helpful imenu-list lsp meson nginx pass prettier systemd

#+END_SRC
We also have the RestClient layer enabled for which I enabled the Org
compatibility support.
#+BEGIN_SRC emacs-lisp
(restclient :variables

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
shell-default-height 40

*** Custom layers
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Custom_layers-69473533

Lastly, three custom layers have been enabled: a w3m layer, and two of my
custom layers for Dired and for conlanging tools.
#+BEGIN_SRC emacs-lisp

* Init
:PROPERTIES:
:header-args:emacs-lisp: :mkdirp yes :tangle ~/.config/emacs/private/spacemacs-init.el :exports code :results silent
:CUSTOM_ID: Init-99a4b561
:END:
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
(defun dotspacemacs/init ()
(setq-default
;; default Spacemacs configuration here
))
#+END_SRC
** 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=~/.config/emacs/.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=.

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

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

** 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

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

#+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)

#+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

#+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.
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-default-font '("Cascadia Code"

#+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

*** 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

#+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

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

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 75)
#+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

#+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

#+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

#+BEGIN_SRC emacs-lisp

Also, when I have two Dired buffers opened side by side, I generally want

directories first, non-hidden first.

When I’m in Eshell, sometimes I wish to open multiple files at once in

"Also find all files within a list of files. This even works recursively."
(if (listp filename)
(loop for f in filename do (find-file f wildcards))

current path depends on the value of ~phundrak/prompt--abbreviate~, if it

[[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
#+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.
#+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.
#+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.
#+BEGIN_SRC emacs-lisp
(add-hook 'org-mode-hook
(lambda ()
(add-hook 'before-save-hook
(lambda ()
(when (and (eq major-mode 'org-mode)
(eq buffer-read-only nil))

**** Org babel languages
: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 |
| makefile |
| python |
| sass |
| scheme |

#+NAME: org-babel-languages-gen
#+BEGIN_SRC emacs-lisp :exports none :tangle no :var languages=org-babel-languages-table[,0] :cache yes :results replace
(mapconcat (lambda ($language) (format "(%s . t)" $language))
languages
"\n")
#+END_SRC
#+RESULTS[cf8b81f0da6306f8131e34be6d3742248fdb057b]: org-babel-languages-gen
#+begin_example
(C . t)
(dot . t)
(emacs-lisp . t)
(gnuplot . t)
(latex . t)
(makefile . t)
(python . t)
(sass . t)
(scheme . t)
(shell . t)
#+end_example
The corresponding code is as follows:
#+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:
#+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:
#+BEGIN_SRC emacs-lisp
(setq org-src-tab-acts-natively t)
#+END_SRC
**** Org variables
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_variables-97587637
:END:
***** User information
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_variables-User_information-6c7d5e3f
:END:
Some variables about myself need to be set so Org-mode knows what
information to include in exported files.
#+BEGIN_SRC emacs-lisp
(setq user-full-name "Lucien Cartier-Tilet"
user-real-login-name "Lucien Cartier-Tilet"
user-login-name "phundrak"
user-mail-address "lucien@phundrak.com")
#+END_SRC
***** Visual settings
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_variables-Visual_settings-5d02f4c0
:END:
Visually, I prefer to hide the markers of macros, so let’s do that:
#+BEGIN_SRC emacs-lisp
(setq org-hide-macro-markers t)
#+END_SRC
I also have an issue where small dots precede my org headers. Let’s fix that:
#+BEGIN_SRC emacs-lisp
(setq org-hide-leading-stars nil
org-superstar-leading-bullet ?\s)
#+END_SRC
***** Org behavior
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_variables-Org_behavior-0319db38
:END:
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.
#+BEGIN_SRC emacs-lisp
(setq org-M-RET-may-split-line nil)
#+END_SRC
I also have added a couple of custom structure templates for Org mode (>=
9.3), mainly for source code blocks.
#+begin_src emacs-lisp
(add-to-list 'org-structure-template-alist '("L" . "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.
#+BEGIN_SRC emacs-lisp
;; (setq org-src-window-setup 'split-window-right)
(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.
#+BEGIN_SRC emacs-lisp
(defun phundrak/toggle-org-src-window-split ()
"This function allows the user to toggle the behavior of
`org-edit-src-code'. If the variable `org-src-window-setup' has
the value `split-window-right', then it will be changed to
`split-window-below'. Otherwise, it will be set back to
`split-window-right'"
(interactive)
(if (equal org-src-window-setup 'split-window-right)
(setq org-src-window-setup 'split-window-below)
(setq org-src-window-setup 'split-window-right))
(message "Org-src buffers will now split %s"
(if (equal org-src-window-setup 'split-window-right)
"vertically"
"horizontally")))
#+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.
#+BEGIN_SRC emacs-lisp
(setq org-confirm-babel-evaluate nil)
#+END_SRC
***** Miscellaneous
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_variables-Miscellaneous-ddcb568a

When creating a link to an Org flie, I want to create an ID only if the
link is created interactively, and only if there is no custom ID already
created.
#+BEGIN_SRC emacs-lisp
(setq org-id-link-to-org-use-id 'create-if-interactive-and-no-custom-id)
#+END_SRC
**** Org files exports
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_files_exports-1e194169
: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:
#+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:
#+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.
#+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)
("" "xeCJK" nil)
("" "hyperref" nil)))
#+END_SRC
By the way, reference links in LaTeX should be written in this 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.
#+BEGIN_SRC emacs-lisp
(setq org-latex-pdf-process
'("xelatex -shell-escape -interaction nonstopmode -output-directory %o %f"
"xelatex -shell-escape -interaction nonstopmode -output-directory %o %f"
"xelatex -shell-escape -interaction nonstopmode -output-directory %o %f"))
#+END_SRC
For Reveal.JS exports, I need to set where to find the framework by default:
#+BEGIN_SRC emacs-lisp
(setq org-reveal-root "file:///home/phundrak/fromGIT/reveal.js")
#+END_SRC
I also 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. So, let’s disable it:
#+BEGIN_SRC emacs-lisp
(setq org-use-sub-superscripts (quote {}))
#+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.
#+BEGIN_SRC emacs-lisp
(setq org-html-validation-link nil)
#+END_SRC
**** Custom LaTeX formats
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Custom_LaTeX_formats-8e8dca1c
:END:
I currently have two custom formats for my Org-mode exports: one for general
use (initialy for my conlanging files, hence its ~conlang~ name), and one
for beamer exports.
Below is the declaration of the ~conlang~ LaTeX class:
#+NAME: org-latex-class-conlang
#+BEGIN_SRC emacs-lisp :tangle no
'("conlang"
"\\documentclass{book}"
("\\chapter{%s}" . "\\chapter*{%s}")
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
#+END_SRC
And here is the declaration of the ~beamer~ class:
#+NAME: org-latex-class-beamer
#+BEGIN_SRC emacs-lisp :tangle no
`("beamer"
,(concat "\\documentclass[presentation]{beamer}\n"
"[DEFAULT-PACKAGES]"
"[PACKAGES]"
"[EXTRA]\n")
("\\section{%s}" . "\\section*{%s}")
("\\subsection{%s}" . "\\subsection*{%s}")
("\\subsubsection{%s}" . "\\subsubsection*{%s}"))
#+END_SRC
Both these classes have to be added to ~org-latex-classes~ like so:
#+BEGIN_SRC emacs-lisp :noweb yes
(eval-after-load "ox-latex"
'(progn
(add-to-list 'org-latex-classes

**** Org capture
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_capture-f58979cf
:END:
Org-capture is an amazing feature of Org-mode which allows me to quickly
save links, resources, reminders, and notes in neatly organized org files.
Here they are described:
#+BEGIN_SRC emacs-lisp
(setq
org-conlanging-file "~/org/conlanging.org"
org-default-notes-file "~/org/notes.org"
org-journal-file "~/org/journal.org"
org-linguistics-notes-file "~/org/linguistics-notes.org"
org-novel-notes-file "~/org/novel-notes.org"
org-private-agenda-file "~/org/agenda/private.org"
org-school-agenda-file "~/org/agenda/school.org"
org-wordbuilding-file "~/org/worldbuilding.org")
#+END_SRC
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.
#+NAME: org-capture-shortcuts-table

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/=.

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

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.

**** Org projects
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_projects-5be088cd
:END:
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:
#+BEGIN_SRC emacs-lisp :noweb yes
<<org-proj-config-setup>>
<<org-proj-lang-setup>>
(setq org-publish-project-alist
`(
<<org-proj-config-html>>

***** 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
(setq phundrak//projects-config-target "/ssh:Tilo:~/www/phundrak.com/config"
phundrak//projects-config-source "~/org/config/"
phundrak//projects-config-language "en"
phundrak//projects-config-recursive t)
#+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 SSH via TRAMP. A sitemap is
automatically generated, which comes in handy with the online sitemap that
is available through the navigation bar.
#+NAME: org-proj-config-html

#+END_SRC
We also have the component for all the static files needed to run the
website (mostly images tbh).
#+NAME: org-proj-config-static

#+END_SRC
***** Linguistics website
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Org-mode-Org_projects-Linguistics_website-34b8d4e7
:END:
My linguistics website is made out of three projects. As for the previous
project, let’s declare the common values for these.
#+NAME: org-proj-lang-setup
#+BEGIN_SRC emacs-lisp :tangle no
(setq phundrak//projects-conlanging-target "/ssh:Tilo:~/www/phundrak.com/langue/"

#+END_SRC
The first component
is the one generating the HTML files from the org files.
#+NAME: org-proj-lang-html

We also have the component for the LaTeX and PDF part of the website:

And lastly, we have the component for all the static files needed to run
the website:
#+NAME: org-proj-lang-static
#+BEGIN_SRC emacs-lisp :tangle no

** Editing and modes
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-7dbaf258

*** Default modes
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-Default_modes-50d4e086
:END:
:CUSTOM_ID: User_Configuration-Miscellaneous-Default_modes-b9e1522c
: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:
:CUSTOM_ID: User_Configuration-Miscellaneous-Evil-ab8a36e3
:END:
As a user of Evil, I’m sometimes pissed when I accidentally press ~C-u~ and
it gets me to the top of the document. So, let’s disable it:
#+BEGIN_SRC emacs-lisp
(setq evil-want-C-u-scroll nil)
#+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 from that
are ~message-mode~, ~org-mode~, ~text-mode~ and ~markdown-mode~.
#+BEGIN_SRC emacs-lisp
(mapc (lambda (x)
(add-hook x 'auto-fill-mode)
(add-hook x 'visual-line-mode))
'(message-mode-hook
org-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)
#+END_SRC
For the record, this is from [[http://www.howardism.org/][Howard Abram]]’s [[https://github.com/howardabrams/dot-files][dotfiles]].
** 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
*** 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
navigator and ~oaw~ invokes the weather forecast.
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys
"oac" 'calc
"oaC" 'calendar
"oae" 'eww
"oaw" 'wttrin)
#+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~.
*** 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-file)
#+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.
*** 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
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

** 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
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
The following also allows me to automatically include my signature in my
Emails, to view images in my Emacs buffers and to show me the address of my
contacts and not just their names.
#+BEGIN_SRC emacs-lisp
(setq mu4e-compose-signature-auto-include t
mu4e-view-show-images t
mu4e-view-prefer-html t
mu4e-view-show-addresses t)
#+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 by ~b~. So, for instance, my unread messages are accessed through ~bU~.
#+BEGIN_SRC emacs-lisp
(setq mu4e-bookmarks
`(("maildir:/Inbox AND NOT flag:trashed" "Inbox" ?i)
(,(s-join " "

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.
#+BEGIN_SRC emacs-lisp
(setq mu4e-enable-notifications t
mu4e-alert-email-notification-types '(count))
(with-eval-after-load 'mu4e-alert
(mu4e-alert-set-default-style 'notifications))
(add-hook 'mu4e-view-mode-hook 'visual-line-mode)
#+END_SRC
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 hook ~visual-line-mode~ and ~auto-fill-mode~, but for some reasons
Emacs throws an error when I add them, So I go with ~visual-fill-column-mode~
instead.
#+BEGIN_SRC emacs-lisp
(add-hook 'mu4e-view-mode-hook 'visual-fill-column-mode)
#+END_SRC
On modern-day computers, with wide screens almost everywhere, there is no
reason for the email buffer to open below the email directory and not on its
right, which is why I set the split view to be vertical instead of
horizontal. And to make it more readable, the header window will only occupy
40% of Emacs’ frame, the rest will be given to emails. As you can see, the
width of the mu4e headers is evaluated each time we enter it, so it can react
to the frame being potentially not the same width than earlier or the window
not taking the entire frame. It has to have a minimal size though, I’d say 80
characters is enough for that.
#+BEGIN_SRC emacs-lisp
(setq mu4e-split-view 'vertical)
(add-hook 'mu4e-headers-mode-hook
(lambda ()
(setq mu4e-headers-visible-columns (max 80
(round (* (window-width)

#+END_SRC
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 stream. And I tell Emacs this is the default way to send an
email.
#+BEGIN_SRC emacs-lisp
(setq smtpmail-smtp-server "mail.phundrak.com"

I am unsure yet if this has any effect on mu4e, but this variable should
discourage mu4e from reading rich text emails and instead open them as plain
text. However, I do not wish to discourage opening HTML emails since I can
compile them to PDF or open them in the browser.
#+BEGIN_SRC emacs-lisp
(setq mm-discouraged-alternatives '("text/richtext"))
#+END_SRC
I am still unsure about this variable and if it has an effect on mu4e, but I
wish to set a default web viewer for my HTML emails: w3m. This is not as
effective as sending the email in the browser or rendering it as a PDF file,
but it can be effective enough for some emails.

*** Time in modeline

I like to see what time it is in Emacs. It may be sometimes redundant with
my window manager’s clock, but the latter is not always visible; I might
have, for instance, Emacs in fullscreen. First, I need to tell Emacs a few
things: I want a 24h format, as well as the current date.
#+BEGIN_SRC emacs-lisp

LSP aware:
#+BEGIN_SRC emacs-lisp

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

including some functions or default modes.
**** 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

done via the use of hooks.
#+BEGIN_SRC emacs-lisp

**** ~phundrak/write-to-buffer~
:PROPERTIES:
: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)

#+END_SRC
*** Python

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 shell :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 shell
$ 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
(add-hook 'rust-mode-hook
'(lambda ()
(local-set-key (kbd "TAB") #'company-indent-or-complete-common)
(electric-pair-mode 1)

#+END_SRC
*** Scheme

#+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, ~yay~.
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, =~/.config/emacs= is always in my projects
list (I now use XDG-compliant directories), so let’s also ignore that.
#+BEGIN_SRC emacs-lisp

#+END_SRC
** 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 ~$HOME/.config/emacs/private/snippets/~ and to their
respective mode directory. For instance, my ~caption~ snippet for org-mode
will be exported to ~$HOME/.config/emacs/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

# name: println

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 [[#User_Configuration-Custom_functions-phundrakyas-rust-new-assignments-10f73456][I wrote here]].

The first two snippets are used to add HTML or LaTeX attributes to elements

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.

*** Org misc

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
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"))))
