## 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 current prompt to universal variables.

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

The themes are loaded from the theme directory shipped with fish or a `themes` directory in the fish configuration directory (typically `~/.config/fish/themes`).

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

## 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 to set the prompt.

`fish_config prompt save` saves the current prompt to an autoloaded file.

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