ProFi, a Lua profiler that works with LuaJIT.

[ljdp]

I've created a simple profiler in response to not being able to get LuaProfiler to work with LoveJIT and some other profile not writing pretty reports.

Here's the Gist: https://gist.github.com/2838755

Code: Select all

	Example:
		ProFi = require 'ProFi'
		ProFi:start()
		some_function()
		another_function()
		coroutine.resume( some_coroutine )
		ProFi:stop()
		ProFi:writeReport( 'MyProfilingReport.txt' )

	API:

		ProFi:start( string/once/nil )
		ProFi:stop()

		ProFi:writeReport( string/filename/'ProFi.txt' )
		ProFi:reset()
		ProFi:setHookCount( number/hookCount/0 )
		ProFi:setGetTimeMethod( function/getTimeMethod/os.clock )
		ProFi:setInspect( string/methodName, number/levels/1 )

Looks pretty awesome, one thing I did notice though, is that you're using CPU time, not real time.

I care more about the relative time of functions rather than the actual time they make, I think i'll add a column to display the time as a percentage between the start and stop calls.

Nice work!

Ok it's fixed, I've added a relative time column, the time for each function is accumulative between start/stop and both time and count resets at start.
There's also a setGetTimeMethod if you want to use something different to os.clock, for example:

Code: Select all

ProFi:setGetTimeMethod( love.timer.getMicroTime )

This is fantastic and just the thing I was looking for. Didn't realize the debug library had such a handy hook.

I figured for profiling you would need to use the c api, but I guess not! Never bothered to really research it.

Wow, this is great, just what I was looking for a couple weeks ago. Thanks for your nice work on this.

By the way you might want to update your instructions -- ProFi:end() should be ProFi:stop()
