This library is intended to be used as a lightweight logging facade. This is a very early version that is only able to print log lines prefixed with the level in brackets. In the future I hope to make this a pluggable system that allows libraries to log using this library's interface, but allow end applications to choose the logging backend that actually receives the log statements.

logface can be installed using luarocks.

luarocks install logface

You may also simply download the file log.lua and place it in your working directory.

local log = require "log"

log.info("Hello, world!")

Which will show:

[INFO] Hello, world!

The available levels are:

• trace
• debug
• info
• warn
• error
• fatal
• print

The default level is INFO (and higher).

The level can be set by setting the LUALOG environment to one of the above levels (case insensitive) before logface is required. (Adjusting the log level later is not yet supported.)
