* 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 'lazy)
#+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 |
| edit-indirect | edit region in separate buffer |
| elcord | rich integration of Emacs in Discord |
| magit-gitflow | integrate gitflow in Magit |
| multiple-cursors | I don’t like the layer, I prefer this package alone |
| ob-swift | org-babel package for Swift |
| 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-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 (quote <<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-but-keep-unused)
#+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)

#+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-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

#+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

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
(treemacs :variables

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

*** Internationalization
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Internationalization-69601ff8

**** 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

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
**** 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
node-add-modules-path t)
#+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.
#+BEGIN_SRC emacs-lisp

**** 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= directory.
#+BEGIN_SRC emacs-lisp

#+END_SRC
*** Version control
:PROPERTIES:
:CUSTOM_ID: Spacemacs_layers_and_packages-Layers-Version_control-bc8e286a

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
colors
#+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~.
#+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

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)

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

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

#+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
(set-fontset-font "fontset-default" '(#x1f600 . #x1f64f) "NotoEmoji Nerd Font")

~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

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

#+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~

- ~%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

#+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

#+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

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 [[#User_Configuration-Shortcuts-Toggle-d53c27ef][Keybindings: Toggle]].

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.

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.

**** 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 |

#+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))

#+END_SRC
#+RESULTS[cf8b81f0da6306f8131e34be6d3742248fdb057b]: org-babel-languages-gen
#+begin_example

(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 -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
"xelatex -8bit -shell-escape -interaction nonstopmode -output-directory %o %f"
"xelatex -8bit -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

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-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-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 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:

: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>>

#+END_SRC
***** 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
#+BEGIN_SRC emacs-lisp :tangle no

:auto-preamble t)
#+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
#+BEGIN_SRC emacs-lisp :tangle no

#+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

#+END_SRC
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
("langue-phundrak-com-static"
:base-directory ,phundrak//projects-conlanging-source

** Editing and modes
:PROPERTIES:
:CUSTOM_ID: User_Configuration-Editing_and_modes-7dbaf258
:END:
*** 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:
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 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)
#+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 web browser, ~oaw~ invokes ~woman~ (actually ~helm-man-woman~), and ~oaW~ invokes the weather forecast.
#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys
"oac" 'calc
"oaC" 'calendar
"oae" 'eww
"oaw" 'helm-man-woman
"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.
*** 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
(evil-define-key 'emacs tetris-mode-map "c" 'tetris-move-left)
(evil-define-key 'emacs tetris-mode-map "t" 'tetris-move-down)
(evil-define-key 'emacs tetris-mode-map "s" 'tetris-rotate-prev)
(evil-define-key 'emacs tetris-mode-map "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
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
*** Text
:PROPERTIES:

The last category is a text-related category. Let’s declare it:

** 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)

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.

*** Beautify Org-mode
:PROPERTIES:
:CUSTOM_ID: User-Configuration-Visual-configuration-Beautify-Org-mode-0506af2f
:END:
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.
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~ which seems to stick to Orgmode like hell and I don’t know why.
#+BEGIN_SRC emacs-lisp

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]].

When it comes to the LSP layer, there are some options which are not enabled by default that I want to use, especially some modes I want to take advantage of. This is why I enable first the ~lsp-treemacs-sync-mode~ so treemacs is LSP aware:
#+BEGIN_SRC emacs-lisp

I also enable some layers related to ~dap~, the Debug Adapter Protocol, which works really nicely with LSP. Let’s enable Dap’s modes:
#+BEGIN_SRC emacs-lisp

Here will be stored my configuration directly related to Emacs Lisp, 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 can easily get some documentation on the symbols in the source code. This is 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)))

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

** 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

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]].

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.

Now, Let’s write some snippets for org blocks. The first one is for a comment block, then two snippets for an unnamed and a named Elisp source block, and two others for an unnamed and a named Python source block. There are also two block for generic unnamed source blocks and generic named source blocks.

*** 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"))))
