* Presentation
:PROPERTIES:
:CUSTOM_ID: Presentation-340195eb
:END:
The file present in =~/.config/fish/config.fish= is the configuration file for the [[https://fishshell.com/][fish shell]]. It contains custom functions, environment variables and abbreviations.

Just in case, we might need sometimes to declare the fish function =fish_title= as =true=, so let’s do so.
#+BEGIN_SRC fish
  function fish_title
      true
  end
#+END_SRC

* Fish from within Emacs
:PROPERTIES:
:CUSTOM_ID: Fish_from_within_Emacs-360c0a74
:END:
I sometimes call fish from within emacs, with =M-x ansi-term=. In this case, the variable =TERM= needs to have the value =eterm-color=.
#+BEGIN_SRC fish
  if test -n "$EMACS"
      set -x TERM eterm-color
  end
#+END_SRC

* Tramp remote access
:PROPERTIES:
:CUSTOM_ID: Tramp_remote_access-72aedec2
:END:
When accessing from a remote machine our computer from Emacs, tramp needs a precise shell appearance: a simple =$= followed by a space after which to put the commands it needs to execute, and nothing else. Due to this, let’s deactivate and redefine some of the functions defining the appearance of fish.
#+BEGIN_SRC fish
  if test "$TERM" = "dumb"
      function fish_prompt
          echo "\$ "
      end
      function fish_right_prompt; end
      function fish_greeting; end
      function fish_title; end
  end
#+END_SRC

* Regular fish shell appearance
:PROPERTIES:
:CUSTOM_ID: Regular_fish_shell_appearance-c3e532e1
:END:
Now, there is only one function I modify when it comes to the appearance of fish when I’m the one using it: the ~fish_greeting~ function. I use it to give me an overview of my computer’s status, including its hostname, uptime, disks usage, ram usage, swap usage, and networking.
#+BEGIN_SRC fish
  set RED '\033[0;31m'
  set GREEN '\033[0;32m'

The theme I use for fish is [[https://github.com/oh-my-fish/theme-bobthefish][bobthefish]], which by default puts a really long timestamp to the right of the prompt. I want something shorter, so here is the variable to set, using the format specified in ~date(1)~.
#+BEGIN_SRC fish
  set -g theme_date_format "+%g-%m-%d %H:%M:%S"
#+END_SRC

I also wish to have a kinda different newline prompt, so let’s set it:
#+BEGIN_SRC fish
  set -g theme_newline_prompt 'λ '
#+END_SRC

* Global variables
:PROPERTIES:
:CUSTOM_ID: Global_variables-1c84df8b
:END:
In order to keep some other code clean, I set the ~$BROWSER~ variable so I don’t have to call my web browser directly but rather with this variable.
#+BEGIN_SRC fish
  set -gx BROWSER firefox
#+END_SRC

Sometimes, software will rely on =SUDO_ASKPASS= to get a GUI from which it can get the sudo password. So, let’s declare it.
#+BEGIN_SRC fish
  set -gx SUDO_ASKPASS ~/.local/bin/askpass
#+END_SRC

** Development
:PROPERTIES:
:CUSTOM_ID: Global_variables-Development-76b3ff13
:END:
Now, let’s declare our editor of choice, EmacsClient; not Emacs itself since it will most often be just quick edits, nothing too heavy, if it is called from the ~EDITOR~ variable (from Git, for example), or from the ~VISUAL~ variable.
#+BEGIN_SRC fish
  set -gx EDITOR emacsclient -c
  set -gx VISUAL emacsclient -c
#+END_SRC

We also need to set the path to the Dart SDK.
#+BEGIN_SRC fish
set -gx DART_SDK /opt/dart-sdk/bin
#+END_SRC

And we also need to specify where the Android SDK it located.
#+BEGIN_SRC fish
set -gx ANDROID_HOME $HOME/Android/Sdk
#+END_SRC

Still related to Dart and Flutter development,
#+BEGIN_SRC fish
  set -gx CHROME_EXECUTABLE /usr/bin/chromium
#+END_SRC

Next, we have two variables from Deno, the Node.js destroyer. Its base directory will be set in my XDG config directory, and its binaries will be located in my local binaries directory (see below).
#+BEGIN_SRC fish
  set -gx DENO_DIR $HOME/.config/deno
  set -gx DENO_INSTALL_ROOT $HOME/.local/bin/deno
#+END_SRC

Finally, some development packages require the =PKG_CONFIG_PATH= to be set, so let’s do so.
#+BEGIN_SRC fish
  set -gx PKG_CONFIG_PATH /usr/local/lib/pkgconfig/ $PKG_CONFIG_PATH
#+END_SRC

** ~$PATH~
:PROPERTIES:
:CUSTOM_ID: Global_variables-$PATH-e1320303
:END:
A variable available with the fish shell is ~fish_user_paths~ which lists custom paths to binaries specified by the user. Using this variable ensures they are included in the ~$PATH~ variable only once without the need to set it directly. For instance, my ~PATH~ variable needs Rust’s Cargo’s binaries, Go’s binaries, my own executables, and some more.

#+NAME: extra-paths
| additional path           | what it leads to                     |
|---------------------------+--------------------------------------|
| $HOME/.pub-cache/bin      | Dart binaries and executables        |

| $HOME/.cabal/bin          | Haskel binaries                      |

#+NAME: generate-extra-paths
#+BEGIN_SRC emacs-lisp :var paths=extra-paths[,0] :exports none :cache yes
  (mapconcat (lambda (x) x)
             paths " \\\n")
#+END_SRC

** System monitoring
:PROPERTIES:
:CUSTOM_ID: Abbreviations-System_monitoring-bd909755
:END:
Here I have some abbreviations which are quite useful when performing some system monitoring. With =df=, we can get an overview of our filesystem usage, while with =diskspace= we get some more precise information. =meminfo= is a call to =free= with sane defaults, and similar to =meminfo=, we also have =gpumeminfo= so we can get a quick look at the memory-related logs of our X session. I also declared =cpuinfo= an alias of =lscpu= in order to keep consistent with =meminfo=. =pscpu= gives us information on what the CPU is running right now, and =pscpu10= limits that to the top 10 threads. Similarly, =psmem= gives us information on the memory usage of the current threads, and =psmem10= only the ten most important threads in terms of memory usage.
#+NAME: mgmt-abbr

** System management (packages and services)
:PROPERTIES:
:CUSTOM_ID: Abbreviations-System_management_(packages_and_services)-7249fbb7
:END:
I added some of these abbreviations due to how often I have to write the whole thing.

*** Package management
:PROPERTIES:
:CUSTOM_ID: Abbreviations-System_management_(packages_and_services)-Package_management-efbcdf0f
:END:
The first command is =remove= which removes a package from my system, as well as its dependencies no longer needed. =p=. =pacman='s or =yay='s. This is why I simply type =purge=. And if I want to simply seach among the =pacman= repos, I can type =search=. Otherwise, if I want to include AUR results, I’ll use =yay=.

#+NAME: pm-abbr
| abbreviation | command            |
|--------------+--------------------|
| remove       | sudo pacman -Rscnd |
| p            | sudo pacman        |

#+END_SRC

*** Service management
:PROPERTIES:
:CUSTOM_ID: Abbreviations-System_management_(packages_and_services)-Service_management-8c5ae482
:END:
I don’t have the muscle memory of =systemctl=. So instead, I simply type =c= when I want to do something user service related. And if I want to manipulate system services, I can instead type a simple capital =S=.
#+NAME: service-abbr
| abbreviation | command   |
|--------------+-----------|

#+BEGIN_SRC fish
  <<generate-abbr(table=service-abbr)>>
#+END_SRC

** Development
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Development-d6050ca4
:END:
A good amount of these commands are development related, especially when it comes to compilation or Docker.

*** CMake
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Development-CMake-f2951675
:END:
I have the following abbreviations so I can quickly run CMake and create a configuration for debug or release profiles.
#+NAME: abbr-cmake

#+END_SRC

*** Docker
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Development-Docker-2d0a1288

And of course, when it comes to Docker Compose, I don't have time to write the full command, so I use these instead.
#+NAME: abbr-docker

*** Text editors
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Development-Text_editors-5a23df47
:END:
I greatly prefer to use Emacsclient as my main text editor; Emacs has basically all I need. So, it's only normal I have an abbreviation to launch a new instance of it. However, in a graphical environment, this will launch a new graphical window of Emacs. To launch a terminal instance, I'll use ~enw~ (~nw~ stands for the option “nowindow” ~-nw~ of Emacs). I also wish to completely stop using other text editors, such as ~vi~, ~vim~, ~nano~ and ~ed~, so let's all add their command as an abbreviation for Emacs.

#+NAME: abbr-text-ed
| abbreviation | command            |
|--------------+--------------------|
| e            | emacsclient -c     |
| enw          | emacsclient -c -nw |
| vi           | emacsclient -c     |
| vim          | emacsclient -c     |
| nano         | emacsclient -c     |
| ed           | emacsclient -c     |

Here is the corresponding fish configuration:
#+BEGIN_SRC fish :noweb yes

#+END_SRC

*** Compilation
:PROPERTIES:

*** Git
:PROPERTIES:

** LaTeX
:PROPERTIES:
:CUSTOM_ID: Abbreviations-LaTeX-76865eb9
:END:
Yes, although I use org-mode, I still have some use for LaTeX, especially when it comes to PDF exports of my org files. Hence why I use the LaTeX package manager. It is recommended to use ~tllocalmgr~ instead of ~tlmgr~, but I can never remember the command, and the latter is faster to type, so time for an abbreviation. Same goes for ~texhash~ which must be run as sudo.
#+NAME: latex-abbr
| abbreviation | command      |
|--------------+--------------|
| tlmgr        | tllocalmgr   |

** Some security measures
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Some_security_measures-489cb521
:END:
Some commands can be quite dangerous when not used properly, which is why I added default flags and options so I can get warnings before things get ugly. The =-i= and =-I= add prompts in case we might not want to do what we asked the shell to do. Notice =lns= which creates symlinks, =rmd= which removes directories, =rmf= which forces deletion, and =rmdf= which forces the delition of a directory. Notice also the =--preserve-root= which will prevent me from accidentally removing the root folder. I added the same option to =chgrp=, =chmod=, and =chown=.
#+NAME: sec-abbr
| abbreviation | command                  |
|--------------+--------------------------|

** Typos
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Typos-370bbb27
:END:
Let's admit it, we all make typos from time to time in the shell, and some are recurrent enough we make abbreviations or aliases of the correct command. Well, I have some of my abbreviations which were make exactly because of this. Sometimes for some reasons, my brain makes me write ~clean~ instead of ~clear~. So, let's just replace the former by the latter. I'm also very bad at typing ~exit~. And sometimes I suck at typing ~htop~. ~q~ isn't a typo per se, instead just a habit I have.
#+NAME: typo-abbr
| abbreviation | command |
|--------------+---------|
| clean        | clear   |
| exi          | exit    |
| exti         | exit    |

** Misc
:PROPERTIES:

Finally, some miscellaneous abbreviations that don't really fit into any of the above categories.

*** Media
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-Media-e4b85d56

Here you will find various commands related to media in general. the first one is a command to play some chillhop from the [[https://www.youtube.com/user/Chillhopdotcom][Chillhop YouTube channel]]'s livestream.
#+BEGIN_SRC fish
  abbr chill 'mpv --force-window=no --no-video "https://www.youtube.com/user/Chillhopdotcom/live" &'
#+END_SRC

When it comes to mpv, I do not want to force it to open a graphical window if for example I want to listen to an audio file. I also do not want any border on that window. So, I declared this abbreviation.
#+BEGIN_SRC fish
  abbr mpv 'mpv --no-border --force-window=no'
#+END_SRC

When I want to download a song from YouTube, I'll just use the command ~flac videoIdentifier~ to get it through ~youtube-dl~.
#+BEGIN_SRC fish

Some sane default options for ~sxiv~, a simple X image Viewer. This includes playing GIFs and not displaying the filename below. Sxiv will also open in fullscreen and will fit the displayed image to the frame. I also abbreviated ~feh~ to sxiv, old habits die hard.
#+BEGIN_SRC fish
  abbr sxiv 'sxiv -abfs f'
  abbr feh 'sxiv -abfs f'

Finally, let's declare the following abbreviation that will launch an mpv instance displaying my webcam:
#+BEGIN_SRC fish
  abbr webcam 'mpv --demuxer-lavf-format=video4linux2 --demuxer-lavf-o-set=input_format=mjpeg av://v4l2:/dev/video0'
#+END_SRC

*** Sudo
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-Sudo-aef0214a
:END:
First, I make it so that ~sudo~ comes with the ~-A~ switch in order to call my custom graphical script for getting my password (see [[file:bin.org::#Askpass-d0d7a8c0][askpass]]). I also made it so ~please~ is an equivalent to ~sudo -A~ as a joke.
#+BEGIN_SRC fish
  abbr please 'sudo -A'
#+END_SRC

*** History
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-History-a2124b23
:END:
I also find it more intuitive and faster to just write ~hist~ instead of ~history~, so let's declare that.
#+BEGIN_SRC fish
  abbr hist history
#+END_SRC

*** Compression
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-Compression-4fd4ffef
:END:
It seems it's just like many other people, but I cannot for the life of me remember the syntax of ~tar~. So, I made the following abbreviations, and one day hopefully, after seeing the abbreviations' expansion over and over I'll remember the command like I did for the abbreviation of ~remove~ (see [[#Abbreviations-System_management_(packages_and_services)-Package_management-efbcdf0f][Package management]]).
#+NAME: tar-abbr
| abbreviation | command   |
|--------------+-----------|
| compress     | tar -czf  |
| untar        | tar -xvzf |

#+BEGIN_SRC fish
  <<generate-abbr(table=tar-abbr)>>
#+END_SRC

*** exa

#+NAME: exa-abbr

*** Network Management

:CUSTOM_ID: Abbreviations-Misc-Network_Management-0b7fc91d
:END:
First, we have just =nmcli= with sane default options, that is a pretty output with colors.
#+BEGIN_SRC fish
  abbr nmcli 'nmcli -p -c auto'
#+END_SRC

*** NordVPN
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-NordVPN-09438638
:END:
Next, we have some NordVPN-related shortcuts. The first one is a simple abbreviation to =nordvpn=. The second one is a shortcut to connect to a server, and to disconnect from the current server. I also have a couple of shortcuts to quickly connect to some preselected countries, mainly France, Germany, Japan and the US.
#+NAME: nordvpn-abbr
| abbreviation | command                 |
|--------------+-------------------------|
| n            | nordvpn                 |
| nc           | nordvpn c               |
| nd           | nordvpn d               |

By default, continue a download that was interupted.
#+BEGIN_SRC fish
