# This 'run script' serves as a central place to store frequently run commands for this project.

### Config ###
# Top-level configurations, like function prefixes and argument delimeters
set -g run_func_prefix 'run'
set -g run_arg_delimeter ':'


### Commands ###
# Add, edit, and remove commands freely below.
# To add a command simply create a function with this naming scheme: run_{command}.
#
function run_hello
    echo 'hello, world!'
end

function run_hey -a name
    echo "hey, $name!"
end

function run_lang -a command
    function lang_en
        run_hello
    end

    function lang_fr
        echo 'bonjour, le monde!'
    end

    execute_command 'lang' $command
end

### Command Execution ###
# Do not edit, unless you want to alter how to script runs commands.
#
# This script can execute 1 or more commands like makefile. It can also receive 1 argument per
# command in the following format: {command}.{argument}.
#
# Examples:
# ./run hello
# ./run hey:mitchell
# ./run hello hey:mitchell lang:fr
#
