#+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

There are several options:

|
||||
- 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)"'~
