Module pl.config

Reads configuration files into a Lua table.

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

# 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 }
