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

|
||
* Global variables
|
||
:PROPERTIES:
|
||
:CUSTOM_ID: Global_variables-1c84df8b
|
||
:END:
|
||
An important thing to do is to load all variables from my =~/.profile=
|
||
file (which you can find [[https://labs.phundrak.com/phundrak/dotfiles/src/branch/master/.profile][here]]). The [[https://github.com/oh-my-fish/plugin-foreign-env][foreign-env]] plugin comes in handy:
|
||
#+begin_src fish
|
||
fenv source ~/.profile
|
||
#+end_src
|
||
|
||
** Development
|
||
:PROPERTIES:
|
||
:CUSTOM_ID: Global_variables-Development-76b3ff13
|
||
:END:
|
||
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/ $PKG_CONFIG_PATH
|
||
#+END_SRC
|
||
|
||
* Tramp remote access
|
||
:PROPERTIES:
|
||
:CUSTOM_ID: Tramp_remote_access-72aedec2
|
||
:END:
|
||
When accessing from a remote machine our computer from Emacs, tramp needs a
|
||
precise shell appearance: a simple =$= 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.

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.

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

: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.

:PROPERTIES:

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

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

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.

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.

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=.

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~.

*** 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. It will also output to
|
||
stdout the selected files in case I want to pipe them to another
|
||
program.
|
||
#+BEGIN_SRC fish
|
||
abbr nsxiv 'nsxiv -abfos f'
|
||
#+END_SRC
|
||
|
||
The following abbreviation is here so I can easily launch software
|
||
with my Nvidia GPU.
|
||
#+begin_src fish
|
||
abbr nv 'env __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia'
|
||
#+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

|
||
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
|

|
||
| compress | tar -czf |
|
||
| untar | tar -xvzf |

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 |

*** Wget

|
||
By default, continue a download that was interupted.
|

#+BEGIN_SRC fish

abbr wget 'wget --hsts-file="$XDG_DATA_HOME/wget-hsts" -c'
|

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!
|
||
|
||
I also have some private abbreviations I don’t want people to know
|
||
about that I store in a separate configuration file.
|
||
#+begin_src fish
|
||
source $HOME/.config/fish/private.fish
|
||
#+end_src
