Module pl.config

Reads configuration files into a Lua table.

Understands INI files, classic Unix config files, and simple delimited columns of values. See the Guide

# test.config
# Read timeout in seconds
read.timeout=10
# Write timeout in seconds
write.timeout=5
#acceptable ports
ports = 1002,1003,1004

-- readconfig.lua
local config = require 'config'
local t = config.read 'test.config'
print(pretty.write(t))

### output #####
{
  ports = {
    1002,
    1003,
    1004
  },
  write_timeout = 5,
  read_timeout = 10
}
