Module commander

library for custom commands

Introduction

Commander is a library for writing custom commands in Lua. In order to make it easier to write commands for Hilbish, not require separate scripts and to be able to use in a config, the Commander library exists. This is like a very simple wrapper that works with Hilbish for writing commands. Example:

local commander = require 'commander'

commander.register('hello', function(args, sinks)
	sinks.out:writeln 'Hello world!'
end)

In this example, a command with the name of hello is created that will print Hello world! to output. One question you may have is: What is the sinks parameter?

The sinks parameter is a table with 3 keys: in, out, and err. The values of these is a Sink.

• in is the standard input. You can read from this sink to get user input. (This is currently unimplemented.)
• out is standard output. This is usually where text meant for output should go.
• err is standard error. This sink is for writing errors, as the name would suggest.
