Work In Progress

This code is still under development, and doesn't work yet.

Lua Port of the docopt Command Line Processor

docopt creates beautiful command-line interfaces.

docopt is a parser for program command line help messages. It will use the help message itself to validate the arguments passed into the program. And from that it will generate a handy table of the arguments. Create the nicely formatted help message, and then let docopt take care of the rest!

This is the Lua port of the original Python implementation.

Basic Usage

Put the docopt.lua file in your Lua modules search path.

Then in your main code (in this case simple_find.lua) put:

local DOC = require 'docopt'  -- Any local name is fine.

local argument_help = [[
Simple Find Command.

Usage:
  simple_find.lua dir [<dirname>]
  simple_find.lua file [filename]

Options:
  -h --help         Show this screen.
  --version         Show the program version.
  -r --recursive    Recursively search subdirectories too.
]]

local processed_args = DOC.docopt(argument_help, arg)

if processsed_args.dir then
    -- Directory name search
elseif processsed_args.file then
    -- File name search
end

Dependencies

docopt.lua does not require any external libraries, and is compatible with Lua 5.1 and 5.2.
