I see some builtin theme files in /usr/share/fish/tools/web_config/themes
How can I built a file like that and where to put that file? I want to see this theme is fish_config output.
Just to be clear, I have set the colors.
set -l base03 002b36
set -l base02 073642
set -l base01 586e75
set -l base00 657b83
set -l base0 839496
set -l base1 93a1a1
set -l base2 eee8d5
set -l base3 fdf6e3
set -l yellow b58900
set -l orange cb4b16
set -l red dc322f
set -l magenta d33682
set -l violet 6c71c4
set -l blue 268bd2
set -l cyan 2aa198
set -l green 859900
I want to only use these colors. Yes, this is solarized dark theme. I want to customize the builtin Solarized Dark.theme file.
From https://fishshell.com/docs/current/cmds/fish_config.html:
The themes are loaded from the theme directory shipped with fish or a themes directory in the fish configuration directory (typically ~/.config/fish/themes).
You can use fish_config theme dump > ~/.config/fish/themes/my.theme to write out your current theme in .theme format. If you have already set the colors how you like it, that's all there is to it.
If not, you can copy the preset theme file and edit it:
cp /usr/share/fish/tools/web_config/themes/Solarized\ Dark.theme ~/.config/fish/themes/my.theme
The format is basically just set fish_color_normal value, except without the set and no expansions, so a theme file may look like (snippet for illustration):
# name: 'Cool Beans'
# preferred_background: black
fish_color_autosuggestion 666
fish_color_cancel -r
fish_color_command normal
fish_color_comment '888' '--italics'
fish_color_cwd 0A0
fish_color_cwd_root A00
fish_color_end 009900
# ... more colors here
The introductory comments are the name to be shown in fish_config, and the background to use when showing it there.
Because there are no expansions, you'll have to set the actual variables - your set -l base03 002b36 won't work here, you'll have to actually give the variable the value. So it may be easier to do that interactively and dump the theme out.
Or you can always just make a full script in e.g. ~/.config/fish/conf.d/ that has all scripting powers available - variable expansions, if conditions, etc.
