Fish Shell: How to quit into the current directory

[cleissonalves]

There are two methods

1. Using a keymap (The simple method)

Add the keymap to ~/.config/joshuto/keymap.toml. You can change the key if you want. I used x.

[default_view]

keymap = [
  #...
  { keys = ["x"], commands = ["shell fish"] },
  #...
]

Add joshuto funtion alias(Optional)

First create the file j.fish inside the directory ~/.config/fish/functions.

Add the following content to the file and save it.

function j
    command joshuto $argv
end

The name of the file and the name of the function must be the same.

This name will be used to run joshuto in the terminal. In my example, I used j.

So, to run joshuto in the terminal i just type:

j

And to exit into the current directory, i press:

x

2. Using a function (a little more complicated)

First create the file j.fish inside the directory ~/.config/fish/functions.

Add the following content to the file and save it.

function j
    set OUTPUT_FILE (mktemp -t "joshuto-cwd.XXXXXX")

    env joshuto --output-file $OUTPUT_FILE $argv
    set exit_code $status

    switch $exit_code
        case 0
            # Regular exit
            # No action needed
        case 101
            # Output contains current directory
            set JOSHUTO_CWD (cat $OUTPUT_FILE)
            cd $JOSHUTO_CWD
        case 102
            # Output selected files
            # No action needed
        case '*'
            echo "Exit code: $exit_code"
    end
end

The name of the file and the name of the function must be the same.

This name will be used to run joshuto in the terminal.

In my example, I used j.

So, to run joshuto in the terminal i just type:

j

Check the keymap that exits joshuto with quit --output-current-directory in the ~/.config/joshuto/keymap.toml.

The default is:

[default_view]

keymap = [
  #...
  { keys = ["Q"], commands = ["quit --output-current-directory"] },
  #...
]

You can change the key if you want.

Then when exiting joshuto with this key, the fish shell will use the current directory.
