#+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"
set SSH_AUTH_SOCK $XDG_RUNTIME_DIR/ssh-agent.socket

* 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' -"~
#+begin_src fish
set -x MANPAGER "sh -c 'col -bx | bat -l man -p'"
#+end_src
* Text editing mode:
You can choose between:
- emacs mode: ~fish_default_key_bindings~
- vi mode: ~fish_vi_key_bindings~
#+begin_src fish
function fish_user_key_bindings

perl-rename 'y/A-Z/a-z/' * && perl-rename 'y/ /-/' *

#+begin_src fish
function polish
setxkbmap -model pc104 -layout pl -option compose:rctrl
end
#+end_src

end
#+end_src
** 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.
#+begin_src fish
function vpssh
sshfs phil@46.38.232.163:/srv/ ~/remote/vps-srv -p 2222 -o identityFile=~/.ssh/id_ed25519_nopass -o reconnect
