Lunar Shell

Lunar Shell (lush) is an open source unix shell with a single goal in mind. That goal is to offer the ability to write shell scripts for your operating system entirely in Lua. The Lua scripting language has many powerful features that allow for more control in the hands of the user to automate tasks on their machine.

Note

Lunar Shell is very early in development and may be lacking in many features common of other Linux shells.

Compiling/Installation

Clone the repo and run the install script to get the development version. If you want the most recent stable version download the source code zip from the most recent release. Extract it and run the install script. This will also automatically set your system shell to Lunar Shell, you will need to log out and back in for the changes to take effect.

git clone https://github.com/BanceDev/lush.git
cd lush
sh install.sh

To update Lunar Shell pull the repo/download the newest release and then run the install script again.

Lua Shell Scripting

-- example lua script to compile a C file
if args ~= nil and args[1] ~= nil then
	if args[1]:match("%.c$") then
		lush.exec("gcc -o " .. args[1]:sub(1, -3) .. " " .. args[1])
	end
else
	print("must pass a C file to compile")
end

With the robust and ever growing Lua API that Lunar Shell has builtin, not only can you create powerful shell scripts to automate your workflow but also reap the benefits of having an easy to understand scripting language embedded into your command line.

To run a Lua script with Lunar Shell just type the name of the lua file you want to run followed by any arguments you want to pass to the script. Lunar Shell will automatically search the current working directory as well as the ~/.lush/scripts directory and then execute the file if it locates a match.

Lunar Shell also entirely supports the Lua interpreter, running on version 5.4. This means you can also just run Lua programs you write like native apps in your shell, no need to make any calls to the API.

Using the Lunar Shell Lua API

Using the Lunar Shell API to make your own scripts is super simple. Upon installing Lunar Shell you can find an example script located at ~/.lush/scripts/example.lua this script acts as a self documenting guide on how to use the API. Every function that exists in the API can be found in the example script, along with helpful comments to explain what the functions do.
