Mog

A simple task runner

Define your tasks in a .mog file and run them with the mog command. Indentation is done with the tab character or 4 spaces. Define a task named 'default' to be ran when mog is called without a task name. The biggest difference between mog and other task runners is that they all run each line in a seperate shell by default. Mog however will run the commands for a given task in the same shell instance which really helps with stuff like sourcing nvm. You don't have to add '&&' to every command and put '. ~/.nmv/nvm.sh' everywhere over and over.

Features

• variables (just strings)
• shell eval with []
• interpolation of variables using {} (unless the { has a $ in front, in which case it is left alone for the shell to interpret)
• escape the [ and { characters with \
• additional cli arguments are passed to the task being ran
• task descriptions with @desc() decorator
• single line comments with #
• importing other .mog files and using the tasks or variables with dot syntax
• call another task in the middle of a task

Installation

curl -fsSL https://raw.githubusercontent.com/ayehavgunne/mog/main/get_mog.sh | bash

Then add it to your path or run mog symlink to automatically create a symbolic link from it's current location to ~/.local/bin/mog

What does it look like?

# a comment

# an import block
import (
	path/to/other/dir/with/.mog/file
	path/to/another/dir as my_alias
)

# variable declarations
py_version = 3.13
py = python{py_version} # variable string interpolation
v_path = [which v] # storing a shell eval into a variable

# the default task which is executed when calling a bare 'mog' with no arguments
default:
    {run}

@desc(run my project) # description to show up when running 'mog -l'
run:
	echo ${EDITOR} # task body is plain shell scripting
	{py} my_script.py # with mog string interpolation on top

@desc(for testing)
test:
	echo {v_path}
	sleep 2
	echo {$1} # just like bash scripts or functions
	echo {$2} # you can pass any extra cli arguments exactly
	echo {$@} # where you need to with these special variables
	echo {$"@"} # they behave exatly the same as bash's equivalents
	echo {$*}
	echo {$"*"}
	echo {$#}
