#+title: fish config #+PROPERTY: header-args :tangle config.fish * Intro This is the fish config I use. It's largely a copy of [[https://gitlab.com/dwt1][Derek Taylor's]] [[https://gitlab.com/dwt1/dotfiles/-/blob/master/.config/fish/config.fish][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. #+begin_src fish set -e fish_user_paths set -U fish_user_paths $HOME/.local/bin $HOME/Applications $HOME/.cabal/bin $HOME/.ghcup/bin $fish_user_paths #+end_src * Exports #+begin_src fish set fish_greeting set TERM "xterm-256color" set EDITOR "emacsclient -t -a ''" set VISUAL "emacsclient -c -a emacs" set QT_QPA_PLATFORMTHEME "qt6ct" #+end_src * 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\" --max=] Draw sparklines" echo "examples:" echo " spark 1 2 3 4" echo " seq 100 | sort -R | spark" echo " awk \\\$0=length spark.fish | spark" case \* echo $argv | spark $argv end return end command awk -v FS="[[:space:],]*" -v argv="$argv" ' BEGIN { min = match(argv, /--min=[0-9]+/) ? substr(argv, RSTART + 6, RLENGTH - 6) + 0 : "" max = match(argv, /--max=[0-9]+/) ? substr(argv, RSTART + 6, RLENGTH - 6) + 0 : "" } { for (i = j = 1; i <= NF; i++) { if ($i ~ /^--/) continue if ($i !~ /^-?[0-9]/) data[count + j++] = "" else { v = data[count + j++] = int($i) if (max == "" && min == "") max = min = v if (max < v) max = v if (min > v ) min = v } } count += j - 1 } END { n = split(min == max && max ?
