* 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 display the output of [[https://labs.phundrak.com/phundrak/pumo-system-info][a utility I wrote]].
#+BEGIN_SRC fish
function fish_greeting
    which pumo-system-info 2&> /dev/null && pumo-system-info
end
#+END_SRC

For my fish prompt, I use [[https://starship.rs][starship]], a shell-agnostic prompt. Let’s load it:
#+begin_src fish
starship init fish | source
#+end_src

* Setting up external tools
:PROPERTIES:
:CUSTOM_ID: Setting-up-external-tools-2r4b97p0bbj0
:END:
** Starship configuration
:PROPERTIES:
:header-args:toml: :tangle ~/.config/starship.toml
:CUSTOM_ID: Starship-configuration-lpz4tz410bj0
:END:
As mentioned above, starship is a shell-agnostic prompt, written in Rust and which can be configured separately from the shell. I decided to configure it here though, since fish is the only shell I use which is compatible with starship.

First I’ll modify the default format variable, removing the modules I don’t need.
#+begin_src toml
format = """
$username\
$hostname\
$shlvl\
$singularity\
$kubernetes\
$directory\

$env_var\
$custom\
$cmd_duration\
$line_break\
$jobs\
$battery\
$time\
$status\
$shell\
$character"""
#+end_src

I want starship to be able to detect Lisp files, be it CommonLisp or EmacsLisp. Unfortunately, it seems nerd-font doesn’t have any symbol for either language, so I’m just using a lambda character.
#+begin_src toml
[custom.lisp]
extensions = ["lisp", "el"]
symbol = "λ "
style = "bold green"
#+end_src

Finally, let’s disable all modules I don’t need.
#+begin_src toml
[cobol]
disable = true
[dotnet]
disable = true
[elixir]
disable = true
[elm]

** Loading ~zoxide~
:PROPERTIES:
:CUSTOM_ID: Setting-up-external-tools-Loading-zoxide-y97b97p0bbj0
:END:
~zoxide~ is a smarter ~cd~ command, accessible through ~z~. It can be loaded like so:
#+begin_src fish
zoxide init fish | source
#+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

In general, I prefer using ~bat~ to ~less~, although the former relies on the
latter, but ~bat~ provides nice wrapping around ~less~, including syntax
highlighting. Let’s set the manpager to bat then:
#+BEGIN_SRC fish
set -x MANPAGER "sh -c 'col -bx | bat -l man -p'"
#+END_SRC

#+begin_src fish
set -x XMODIFIERS
#+end_src

#+begin_src fish
if test -n "$DESKTOP_SESSION"
    set -x (gnome-keyring-daemon --start | string split "=")
end
#+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                     |
|---------------------------+--------------------------------------|

#+NAME: generate-extra-paths
#+BEGIN_SRC emacs-lisp :var paths=extra-paths[,0] :exports none :cache yes

So, let’s set our user paths:
#+BEGIN_SRC fish :noweb yes
set -g fish_user_paths \
<<generate-extra-paths()>>
#+END_SRC

Abbreviations are a great way to keep correctly track of which commands are run
in the shell without polluting the history of the shell with obscure commands.
When typing an abbreviation, fish will replace it with replace it with its
expanded equivalent. Below are some of the abbreviations I use. Be aware some of
them that invoke GUI programs can be invoked through ~devour~ which will make
the terminal disappear while the program runs, and once the GUI program exists
the terminal window will come back.

** 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
| abbreviation | command                                    |

** 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 =paru='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 =paru=.

#+NAME: pm-abbr
| abbreviation | command          |
|--------------+------------------|
| remove       | sudo pacman -Rsc |
| purge        | paru -Sc         |

#+BEGIN_SRC fish

#+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          |
|--------------+------------------|
| s            | systemctl        |

#+END_SRC

** Development
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Development-d6050ca4

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

I have the following abbreviations so I can quickly run CMake and create a
configuration for debug or release profiles.
#+NAME: abbr-cmake

*** 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

#+END_SRC

*** 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. If launched in the terminal, I’ll usually want Emacs to be displayed in
CLI mode and not in GUI mode, otherwise I would invoke it with my WM’s shortcut.
In case we want to launch Emacs in GUI mode anyways, ~egui~ is available too.

#+NAME: abbr-text-ed
| abbreviation | command               |
|--------------+-----------------------|
| e            | emacsclient -c -nw    |

#+END_SRC

*** Compilation
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Development-Compilation-dd066050

By default, I set ~clang~, ~clang++~, ~gcc~ and ~g++~ to the latest standard and
with the ~-Wall~ flag activated.
#+NAME: abbr-comp

*** Git

And let's face it: we all at one point just wanted to commit our code without
thinking about the message, to just get over with it. Don't worry, I got you
covered.
#+NAME: abbr-git

** 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   |

#+END_SRC

** 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                   |
|--------------+---------------------------|
| cp           | cp -i                     |

** 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~.
#+NAME: typo-abbr
| abbreviation | command |
|--------------+---------|
| clean        | clear   |
| exi          | exit    |
| exti         | exit    |

Here is the corresponding fish configuration:
#+BEGIN_SRC fish

** Misc
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-c2631eb6
:END:
Finally, some miscellaneous abbreviations that don't really fit into any of the
above categories.

*** Media
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-Media-e4b85d56
:END:
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
abbr flac 'youtube-dl -x --audio-format flac --audio-quality 0 -o "~/Music/%(uploader)s/%(title)s.%(ext)s"'
#+END_SRC

Some sane default options for [[https://github.com/nsxiv/nsxiv][~nsxiv~]]. This includes playing GIFs and
not displaying the filename below. Nsxiv will also open in fullscreen
and will fit the displayed image to the frame.
#+BEGIN_SRC fish
abbr nsxiv 'nsxiv -abfs f'
abbr sxiv  'nsxiv -abfs f' # old habits die hard
#+END_SRC

Finally, let's declare the following abbreviation that will launch an mpv
instance displaying my webcam:
#+BEGIN_SRC fish
abbr webcam 'devour 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 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
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-exa-e1b528b9
:END:
#+NAME: exa-abbr
| abbreviation | command                                    |
|--------------+--------------------------------------------|
| exa          | exa -halg@ --group-directories-first --git |
| lsl          | exa -halg@ --group-directories-first --git |

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

*** Network Management
:PROPERTIES:
: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               |
| ncf          | nordvpn c France        |
| ncg          | nordvpn c Germany       |
| ncj          | nordvpn c Japan         |
| ncu          | nordvpn c United_States |

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

*** Wget
:PROPERTIES:
:CUSTOM_ID: Abbreviations-Misc-Wget-27f4bebf
:END:
By default, continue a download that was interupted.
#+BEGIN_SRC fish
abbr wget 'wget -c'
#+END_SRC

* Last thing before we’re done
:PROPERTIES:
:CUSTOM_ID: Last-thing-before-we-re-done-670f1461
:END:
For some reason, Fish began searching for packages when I enter a command name
wrong. For instance, if I type ~vim~, I get something like this:
#+BEGIN_SRC text :tangle no
$ vim
fish: Unknown command: vim
usr/bin/vim is owned by extra/gvim 8.2.2653-1
usr/bin/vim is owned by extra/vim 8.2.2653-1
#+END_SRC

But I don’t want that, it slows down my shell. So, in order to fix that, we need
the following lines:
#+BEGIN_SRC fish
function fish_command_not_found
    __fish_default_command_not_found_handler $argv
end
#+END_SRC

Tadah! No more package suggestions from fish!
