# My fish config. Not much to see here; just some pretty standard stuff.

### ADDING TO THE 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/.bin  $HOME/.local/bin $HOME/.config/emacs/bin $HOME/Applications /var/lib/flatpak/exports/bin/ $fish_user_paths

### EXPORT ###
set fish_greeting                                 # Supresses fish's intro message
set TERM "xterm-256color"                         # Sets the terminal type
set EDITOR "emacsclient -t -a ''"                 # $EDITOR use Emacs in terminal
set VISUAL "emacsclient -c -a emacs"              # $VISUAL use Emacs in GUI mode

### SET FZF DEFAULTS
set FZF_DEFAULT_OPTS "--layout=reverse --exact --border=bold --border=rounded --margin=3% --color=dark"

### SET MANPAGER
### Uncomment only one of these!

### "nvim" as manpager
set -x MANPAGER "nvim +Man!"

### "less" as manpager
# set -x MANPAGER "less"

### SET EITHER DEFAULT EMACS MODE OR VI MODE ###
function fish_user_key_bindings
  # fish_default_key_bindings
  fish_vi_key_bindings
end
### END OF VI MODE ###

### 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
