Callgrinding in Löve (Helpful performance profiling utility)

[CyaNox]

In my years of debugging various performance problems I came across a program called KCacheGrind. The way it visualized and reprented the data to me was very appealing not to mention easy to read so I was curious if something was available for Löve but didn't encounter anything. So I looked further and stumbled on Profiling Lua with KCacheGrind on the Lua-users wiki.

With some little modifications I was able to make it work just fine in Löve (see attached file).

For the windows users out there KCacheGrind also has a precompiled windows binary.

I choose to not alter the io calls in there to the love.filesystem calls with the reason that I or anyone else might also want to use it outside of love.

Its very simple to use just call profiler.start() from which point you want to start the data collecting and profiler.finish() to stop the data collection and write out the collected information.

I did modify the way it saves the file slightly to embed a timestamp of when it finishes the profiling in case of you doing multiple profile sessions in one application run.

Hope this is useful to someone else aside from me
