largparse

Feature-rich command line parser for Lua inspired by argparse for Python.

WIP.

Something already works:

local largparse = require "largparse"

local parser = largparse.parser()

parser:argument("input", {
   args = 2
})

parser:mutually_exclusive(
   parser:flag("-q", "--quiet"),
   parser:option("-s", "--server")
)

local run = parser:command "run"

run:flag("-f", "--fast")

local args = parser:parse()
