: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: h-97d738f4-1ea0-4f64-a31d-19643486a951
: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 "$EMACS"
set -x TERM eterm-color
end
#+END_SRC
* Tramp remote access
:PROPERTIES:
:CUSTOM_ID: h-6cad2cc9-aef6-4df4-90f9-97053e82072a
:END:
When accessing from a remote machine our computer from Emacs, tramp needs a
precise shell appearance: a simple =$= 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: h-a8434b29-c146-4141-b8f8-1b446c791907
:END:
Now, there is only one function I modify when it comes to the appearance of
fish when I’m the one using it: I simply “delete” the =fish_greeting=
function.
#+BEGIN_SRC fish
function fish_greeting; end
#+END_SRC
* Global variables
:PROPERTIES:
:CUSTOM_ID: h-0eff37da-af9f-4546-8ad3-201961a2200f
:END:
Some global variables might sometimes be needed and need to be modified. This
is for example the case with my =PATH= variable in which I add Rust’s Cargo’s
binaries, Go’s binaries and my own executables. And of course, don’t forget
to add the already existing =PATH=.
#+NAME: extra-paths
| additional path | what it leads to |
|---------------------------+--------------------------------------|
| $HOME/.pub-cache/bin | Dart binaries and executables |
| $HOME/.local/bin | Custom executables, see [[file:bin.org]] |
| $HOME/go/bin | Go binaries and executables |
| $HOME/.cargo/bin | Rust binaries and executables |
| $HOME/.gem/ruby/2.6.0/bin | Ruby binaries and executables |
#+NAME: generate-extra-paths
#+BEGIN_SRC emacs-lisp :var paths=extra-paths[,0] :exports none :cache yes
(mapconcat (lambda (x) x)
paths " ")
#+END_SRC
#+RESULTS[d6cf1e9d562d644db1bc6458eca1fc165b065f0c]: generate-extra-paths
: $HOME/.pub-cache/bin $HOME/.local/bin $HOME/go/bin $HOME/.cargo/bin $HOME/.gem/ruby/2.6.0/bin
#+BEGIN_SRC fish :noweb yes
set -gx PATH <<generate-extra-paths()>> $PATH
#+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
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).
#+BEGIN_SRC fish
set -gx EDITOR 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
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
* Abbreviations

:CUSTOM_ID: h-740bd904-3e32-4c09-b0a4-bde16ae2e116

#+BEGIN_SRC emacs-lisp :var table=[] :exports none :tangle no

** System monitoring
:PROPERTIES:
:CUSTOM_ID: h-ec910a8c-9154-48a4-b4cd-df28cb4e54d9
: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 |
|--------------+---------------------------------------------------|
| df | df -H |
| diskspace | sudo df -h \vert grep -E "sd\vert{}lv\vert{}Size" |
| meminfo | free -m -l -t |
| gpumeminfo | grep -i --color memory /var/log/Xorg.0.log |
| cpuinfo | lscpu |
| pscpu | ps auxf \vert sort -nr -k 3 |

** System management (packages and services)
:PROPERTIES:
:CUSTOM_ID: h-78ac23f0-960d-4f56-9cba-64413fd61885
:END:
I added some of these abbreviations due to how often I have to write the
whole thing.
*** Package management
:PROPERTIES:
:CUSTOM_ID: h-281a59aa-4ea0-47ab-a4cc-33fff8d38165
: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 |
| purge | yay -Sc |
| search | yay -Ss |
#+BEGIN_SRC fish
<<generate-abbr(table=pm-abbr)>>
#+END_SRC
*** Service management
:PROPERTIES:
:CUSTOM_ID: h-3a734119-ccee-4cdf-b04c-d55a37dea571
: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 --user |
| S | sudo systemctl |
#+BEGIN_SRC fish
<<generate-abbr(table=service-abbr)>>
#+END_SRC
** Development
:PROPERTIES:
:CUSTOM_ID: h-32ae38a2-41ad-438e-b619-220a63166115
:END:
A good amount of these commands are development related, especially when it
comes to compilation or Docker.
*** CMake
:PROPERTIES:
:CUSTOM_ID: h-887c87aa-b100-4b27-9006-778fd7e3329c
:END:
I have the following abbreviations so I can quickly run CMake and create a
configuration for debug or release profiles.
#+NAME: abbr-cmake
| abbreviation | command |
|--------------+----------------------------------|
| cdebug | cmake -DCMAKE_BUILD_TYPE=Debug |
| crelease | cmake -DCMAKE_BUILD_TYPE=Release |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish
<<generate-abbr(table=abbr-cmake)>>
#+END_SRC
*** Compilation
:PROPERTIES:
:CUSTOM_ID: h-0beb47e5-d76a-4037-8f58-e8de141e3761
:END:
By default, I set =clang=, =clang++=, =gcc= and =g++= to the latest
standard and with the =-Wall= flag activated.
#+NAME: abbr-comp
| abbreviation | command |
|--------------+----------------------|
| clang | clang -Wall |
| clang++ | clang++ -Wall |
| g++ | g++ -Wall -std=c++17 |
| gcc | gcc -Wall -std=c18 |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish :tangle
<<generate-abbr(table=abbr-comp)>>
#+END_SRC
*** Docker
:PROPERTIES:
:CUSTOM_ID: h-91c7ff90-7b43-4802-be69-5d102281c6d3
:END:
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
| abbreviation | command |
|--------------+---------------------------|
| dc | docker-compose |
| dcd | docker-compose down |
| dcr | docker-compose run --rm |
| dcu | docker-compose up |
| dcub | docker-compose up --build |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish
<<generate-abbr(table=abbr-docker)>>
#+END_SRC
*** Git
:PROPERTIES:
:CUSTOM_ID: h-e72347d4-590e-448c-bc33-0a70fa8ab35b
:END:
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
| abbreviation | command |
|--------------+-----------------------------------------------------|
| randcommit | git commit -m (curl -s whatthecommit.com/index.txt) |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish :tangle
<<generate-abbr(table=abbr-git)>>
#+END_SRC
*** Prolog
:PROPERTIES:
:CUSTOM_ID: h-cbb6c31e-faaa-48c3-a83a-d1f143fdcb8d
:END:
When I launch =swipl=, I prefer to have my terminal cleaned before and
after it runs, I find it more clean.
#+NAME: abbr-prolog
| abbreviation | command |
|--------------+----------------------------|
| swipl | clear && swipl -q && clear |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish
<<generate-abbr(table=abbr-prolog)>>
#+END_SRC
*** Text editors
:PROPERTIES:
:CUSTOM_ID: h-51155e06-872d-4a12-9bf7-ae5eabc256ad
: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
<<generate-abbr(table=abbr-text-ed)>>
#+END_SRC
** LaTeX
:PROPERTIES:
:CUSTOM_ID: h-a8f8a707-90d7-4784-982d-d959b183148e
: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 |
| texhash | sudo texhash |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish
<<generate-abbr(table=latex-abbr)>>
#+END_SRC
** Some security measures
:PROPERTIES:
:CUSTOM_ID: h-dd97ea71-c43f-4b79-8bb7-1f857284b1b4
: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 |
| ln | ln -i |
| lns | ln -si |
| mv | mv -i |
| rm | rm -Iv |
| rmd | rm --preserve-root -Irv |
| rmdf | rm --preserve-root -Irfv |
| rmf | rm --preserve-root -Ifv |
| chgrp | chgrp --preserve-root -v |
| chmod | chmod --preserve-root -v |
| chown | chown --preserve-root -v |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish
<<generate-abbr(table=sec-abbr)>>
#+END_SRC
** Typos
:PROPERTIES:
:CUSTOM_ID: h-4c5a03cd-20a8-437e-87b7-af990780084e
: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 |
| hotp | htop |
Here is the corresponding fish configuration:
#+BEGIN_SRC fish
<<generate-abbr(table=typo-abbr)>>
#+END_SRC
** Misc
:PROPERTIES:
:CUSTOM_ID: h-3a237ec0-c535-42c7-9c60-3d083745b643
:END:
Finally, some miscellaneous abbreviations that don’t really fit into any of
the above categories.
*** Sudo
:PROPERTIES:
:CUSTOM_ID: h-0955e2fc-ec25-41b6-814a-929fa3718dda
: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:~/.local/bin/askpass][.local/bin/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
*** Exit
:PROPERTIES:
:CUSTOM_ID: h-8cf0e895-b919-41a8-ad3d-c5294dc507fd
:END:
Sometimes I find it easier to just type =q= instead of =exit=.
#+BEGIN_SRC fish
abbr q exit
#+END_SRC
*** History
:PROPERTIES:
:CUSTOM_ID: h-162052c5-63c4-435a-b973-422346522c69
: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
*** ~youtube-dl~ related commands
:PROPERTIES:
:CUSTOM_ID: h-177d56dc-39a6-4f4c-a7ba-179dd5c6cac8
:END:
**** Song download from YouTube
:PROPERTIES:
:CUSTOM_ID: h-4bc663a9-b609-4c86-9a4d-a220013c67f9
:END:
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
**** Videos download from YouTube
:PROPERTIES:
:CUSTOM_ID: h-e6e45b59-7620-4d17-ba32-67a33f39cc4b
:END:
I download a LOT of videos from YouTube, generally educative videos that I
do not want to lose to YouTube one day who will decide that such channel is
unworthy of their platform, or if the original author decides to delete
their videos or whatever. So, I use the abbreviation ~ytdl~ to download
either one video, or a whole YouTube channel.
#+BEGIN_SRC fish
abbr ytdl 'youtube-dl -f best -ciw -o "~/Videos/YouTube/%(uploader)s/%(upload_date)s - %(title)s.%(ext)s"'
#+END_SRC
*** MPV
:PROPERTIES:
:CUSTOM_ID: h-3fd5a7eb-4ed4-4b0b-87ca-28f36fb22793
:END:
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
*** Compression
:PROPERTIES:
:CUSTOM_ID: h-05919be3-360a-45c6-8c89-76836375d55b
: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
[[#h-281a59aa-4ea0-47ab-a4cc-33fff8d38165][Package management]]).
#+NAME: tar-abbr
| abbreviation | command |
|--------------+-----------|
| compress | tar -czf |
| untar | tar -xvzf |
#+BEGIN_SRC fish
<<generate-abbr(table=tar-abbr)>>
#+END_SRC
*** Feh
:PROPERTIES:
:CUSTOM_ID: h-41cfc583-14ba-4f15-9578-bc37b432a3ce
:END:
Some sane default options for =feh=, including auto-zoom to fit the picture
to the window, a borderless window, and again scale the image to fit the
window geometry.
#+BEGIN_SRC fish
abbr feh 'feh -Zx.'
#+END_SRC
*** Network Management
:PROPERTIES:
:CUSTOM_ID: h-5f9d4866-3086-4ed9-9ff3-d80a0af36593
: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: h-f35e00a2-ec5b-416d-821f-56040ad1d6b4
: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
*** Webcam
:PROPERTIES:
:CUSTOM_ID: h-465adbc6-cad0-441a-9e54-f5e389e7362d
:END:
#+NAME: webcam-abbr
| abbreviation | command |

*** Wget
:PROPERTIES:
:CUSTOM_ID: h-74f84f1c-433d-488a-88a7-89915c1a3bd5
:END:
By default, continue a download that was interupted.
#+BEGIN_SRC fish
