ProFi, a Lua profiler that works with LuaJIT.

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
--[[
ProFi v1.3, by Luke Perkin 2012. MIT Licence http://www.opensource.org/licenses/mit-license.php.
Example:
ProFi = require 'ProFi'
ProFi:start()
some_function()
another_function()
coroutine.resume( some_coroutine )
ProFi:stop()
ProFi:writeReport( 'MyProfilingReport.txt' )
API:
*Arguments are specified as: type/name/default.
ProFi:start( string/once/nil )
ProFi:stop()
ProFi:checkMemory( number/interval/0, string/note/'' )
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.

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()
