Intro

This is the fish config I use. It's largely a copy of Derek Taylor's fish config. I have some edits in, but it's nothing significant. The majority of the comments are Derek's.

Path

First line removes the path; second line sets it. Without the first line, your path gets massive and fish becomes very slow.

set -e fish_user_paths
set -U fish_user_paths $HOME/apps/bin $HOME/.local/bin $HOME/Applications $HOME/.cabal/bin $HOME/.ghcup/bin $HOME/.deno/bin $fish_user_paths

set -U EDITOR emacsclient -c --alternate-editor=''
set -Ux PASSWORD_STORE_DIR $HOME/enc/keys/pass/
set -U PLANTUML_LIMIT_SIZE 16384

set -e SSH_AGENT_PID
if not set -q gnupg_SSH_AUTH_SOCK_by or test $gnupg_SSH_AUTH_SOCK_by -ne $fish_pid
    set -gx SSH_AUTH_SOCK (gpgconf --list-dirs agent-ssh-socket) 
end

Exports

set fish_greeting
set TERM "xterm-256color"
set EDITOR "emacsclient -t -a ''"
set VISUAL "emacsclient -c -a emacs"
set QT_QPA_PLATFORMTHEME "qt6ct"
set SSH_AUTH_SOCK $XDG_RUNTIME_DIR/ssh-agent.socket
set GNUPGHOME "~/enc/keys/gnupg"
set LEDGER_FILE "~/enc/org/hledger/2023.journal"

Manpager

There are several options:

• bat: set -x MANPAGER "sh -c 'col -bx | bat -l man -p'"
• vim: set -x MANPAGER '/bin/bash -c "vim -MRn -c \"set buftype=nofile showtabline=0 ft=man ts=8 nomod nolist norelativenumber nonu noma\" -c \"normal L\" -c \"nmap q :qa<CR>\"</dev/tty <(col -b)"'
• nvim: set -x MANPAGER "nvim -c 'set ft=man' -"

set -x MANPAGER "sh -c 'col -bx | bat -l man -p'"

Text editing mode:

You can choose between:

• emacs mode: fish_default_key_bindings
• vi mode: fish_vi_key_bindings

function fish_user_key_bindings
    fish_default_key_bindings
end

Autocomplete and highlight colors

set fish_color_normal brcyan
set fish_color_autosuggestion '#7d7d7d'
set fish_color_command brcyan
set fish_color_error '#ff6c6b'
set fish_color_param brcyan

Small functions

backup

function backup --argument filename
    cp $filename $filename.bak
end

copy

Copy things, recursively. Like cp -r.

function copy
    set count (count $argv | tr -d \n)
    if test "$count" = 2; and test -d "$argv[1]"
	set from (echo $argv[1] | trim-right /)

        command cp $argv
    end
end

coln

Print only one column of the output.

    while read -l input
        echo $input | awk '{print $'$argv[1]'}'
    end
end

rown

Print only one row of the output.

function rown --argument index
    sed -n "$index p"

function skip --argument n
    tail +(math 1 + $n)
end

take

Prints only the first n lines of the output.

function take --argument number
    head -$number
end

org-search

Perform a search through your org-agenda-files for a string.

function org-search -d "send a search string to org-mode"
    set -l output (/usr/bin/emacsclient -a "" -e "(message \"%s\" (mapconcat #'substring-no-properties \
        (mapcar #'org-link-display-format \
        (org-ql-query \
        :select #'org-get-heading \
        :from  (org-agenda-files) \
        :where (org-ql--query-string-to-sexp \"$argv\"))) \

alias tozsh="sudo chsh $USER -s /bin/zsh && echo 'Now log out.'"
alias tofish="sudo chsh $USER -s /bin/fish && echo 'Now log out.'"

tb

termbin in your terminal.

alias tb="nc termbin.com 9999"

tips

I'm not sure what this does. Derek's comment is Unlock LBRY tips, which honestly can mean anything. Leaving this in my config just in case it's important.

alias tips="lbrynet txo spend --type=support --is_not_my_input --blocking"

DTOS

These are things that I tend to keep in after first installing DTOS on top of Arch. I don't need much afterwards, so a lot of it is missing. For the full deal, head to Derek's repo, where you can see all the aliases and settings.

Pretty!

colorscript

You can get this script from DT's git, or install them from AUR: shell-color-scripts.

colorscript random

starship prompt

starship init fish | source

Environment variables

set -gx PATH "$HOME/.cabal/bin:$HOME/.ghcup/bin:$PATH"

Phil's stuff

phil-fix-names

Makes directory and file names lowercase, substitutes whitespace for dashes.

function phil-fix-names
    perl-rename 'y/A-Z/a-z/' * && perl-rename 'y/ /-/' *
end

polish

Occasionally my keyboard layout changes. I have not figured out why yet, but this way I can quickly reset it.

function polish
  setxkbmap -model pc104 -layout pl -option compose:rctrl
end

greek

Occasionally I type in greek. This function sets my keyboard layout for it.

function greek
    setxkbmap -model pc104 -layout gr -option compose:rctrl
end

vps

Logs me into my VPS with an ssh key. I use it extensively, so being able to log in without having to type a password is really nice.

function vps
  ssh -p 2222 phil@46.38.232.163 -i ~/.ssh/id_ed25519_nopass
end

vpssh

Mounts my \/srv\/ directory into ~/remote/vps-srv. Really convenient. My websites all run on org-mode, so this makes it very easy to work on them from the convenience of the best text editor.

function vpssh
  sshfs phil@46.38.232.163:/srv/ ~/remote/vps-srv -p 2222 -o identityFile=~/.ssh/id_ed25519_nopass -o reconnect
end

vpsshu

Unmounts the above.

function vpsshu
  fusermount3 -u ~/remote/vps-srv/
end
