LoveProfile for Löve2D

LoveProfiler is an extremely simple logger and profiler for Löve2D framework. It displays useful information about the current state of a running game. It also can log events at three levels: information, warnings and errors. The output of the profiler is displayed on the Löve2D canvas or in the console (terminal).

Installation

Installation is very easy. Just use git clone or copy directory loveprofiler into your game's directory where file main.lua is.

git clone https://github.com/dknight/loveprofiler

Example project structure:

love2dproject/
  loveprofiler/
  main.lua

Usage

The most basic usage, create an instance of love.load() then call start() method inside love.draw().

local LoveProfiler = require("loveprofiler")

function love.load()
  profiler = LoveProfiler:new()
end

function love.draw()
  profiler:start()
end

Configuration

You can find all possible configuration options with detailed description in defaults.lua file. You can override any option when you create a new instance.

local LoveProfiler = require("loveprofiler")

function love.load()
  profiler = LoveProfiler:new{config = {
    driver = "console",
    font_size = 17,
    draw_x = 400,
    color = {0, 0, 1, 1}
  }}
end

function love.draw()
  profiler:start()
end

Drivers

At the moment only 2 drivers are supported: canvas and console. If a driver is set to canvas then information is displayed directly on the Löve2D canvas. If console then output will be displayed in the console (system terminal). See defaults.lua file for more details.

Logging

There are 3 levels of messages:

• information;
• warning;
• error.

You can add a log entry like this:

local LoveProfiler = require("loveprofiler")

function love.load()
  profiler = LoveProfiler:new()
  profiler:addMessage("Your information message", LoveProfiler.LOG_INFO)
  profiler:addMessage("Your warning message", LoveProfiler.LOG_WARN)
  profiler:addMessage("Your error message", LoveProfiler.LOG_ERROR)
end

By default, logs are also saved in a file loveprofiler.log. You can change the logging destination by changing the configuration property log_path = "your_path_to_log_file", see defaults.lua. Also if you set log_path = nil, output won't be saved into file at all.

Disabling logging

To completely disable logging set configuration property log_enabled = false.

Using multiple profilers

You can create as many LoveProfiler instances as you want with different configurations.

local LoveProfiler = require("loveprofiler")

function love.load()
  profiler1 = LoveProfiler:new()
  profiler2 = LoveProfiler:new{config = {
  	driver = "console",
    font_size = 18,
    draw_x = 400,
  }}
end

function love.draw()
  profiler1:start()
  profiler2:start()
end
