FISH_CONFIG(1)

NAME
fish_config - start the web-based configuration interface

SYNOPSIS
fish_config [browse]
fish_config prompt (choose | list | save | show)
fish_config theme (choose | demo | dump | list | save | show)

DESCRIPTION

fish_config is used to configure fish.

Without arguments or with the browse command it starts the web-based configuration interface. The web interface allows you to view your functions, variables and history, and to make changes to your prompt and color configuration. It starts a local web server and opens a browser window. When you are finished, close the browser window and press the Enter key to terminate the configuration session.

If the BROWSER environment variable is set, it will be used as the name of the web browser to open instead of the system default.

With the prompt command fish_config can be used to view and choose a prompt from fish's sample prompts inside the terminal directly.

Available subcommands for the prompt command:

•   choose loads a sample prompt in the current session.

•   list lists the names of the available sample prompts.

•   save saves the current prompt to a file (via funcsave <>).

•   show shows what the given sample prompts (or all) would look like.

    With the theme command fish_config can be used to view and choose a theme (meaning a color scheme) inside the terminal.

    Available subcommands for the theme command:

•   choose loads a sample theme in the current session.

•   demo displays some sample text in the current theme.

•   dump prints the current theme in a loadable format.

•   list lists the names of the available sample themes.

•   save saves the given theme to universal variables <#variables-universal>.

•   show shows what the given sample theme (or all) would look like.

    The -h or --help option displays help about using this command.

THEME FILES

fish_config theme and the theme selector in the web config tool load their themes from theme files. These are stored in the fish configuration directory, typically ~/.config/fish/themes, with a .theme ending.

You can add your own theme by adding a file in that directory.

To get started quickly:

    fish_config theme dump > ~/.config/fish/themes/my.theme

which will save your current theme in .theme format.

The format looks like this:

    # 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

The two comments at the beginning are the name and background that the web config tool shows.

The other lines are just like set variable value, except that no expansions are allowed. Quotes are, but aren't necessary.

Any color variable fish knows about that the theme doesn't set will be set to empty when it is loaded, so the old theme is completely overwritten.

Other than that, .theme files can contain any variable with a name that matches the regular expression '^fish_(?:pager_)?color.*$' - starts with fish_, an optional pager_, then color and then anything.

EXAMPLE

fish_config or fish_config browse opens a new web browser window and allows you to configure certain fish settings.

fish_config prompt show demos the available sample prompts.

fish_config prompt choose disco makes the disco prompt the prompt for the current session. This can also be used in config.fish <#configuration> to set the prompt.

fish_config prompt save saves the current prompt to an autoloaded <#syntax-function-autoloading> file.

fish_config prompt save default chooses the default prompt and saves it.
