Decorators for profiling/timing/tracing individual functions
It’s a collection of decorators for profiling functions. E.g. to profile a single function:
from profilehooks import profile @profile def my_function(args, etc): pass
The results will be printed when the program exits (or you can use @profile(immediate=True)).
If you’re interested in coarse timings and don’t want to pay for the overhead of profiling, use
from profilehooks import timecall @timecall # or @timecall(immediate=True) def my_function(args, etc): pass
Finally, you may be interested in seeing line coverage for a single function
from profilehooks import coverage @coverage def my_function(args, etc): pass
Full documentation is available through pydoc profilehooks after installation.

- Added Python 3.2 compatibility, dropped Python 2.3, 2.4 and 2.5 compatibility.
- Migrated the source repository to https://github.com/mgedmin/profilehooks
- Added a changelog.
- New argument to @timecall: timer (defaults to time.time). Example: @timecall(timer=time.clock)
- Better documentation.
- Added support for cProfile, make it the default profiler when available. Previously profilehooks supported profile and hotshot only.
- Store profile results (when you pass filename to @profile) in pstats format instead of pickles. Contributed by Florian Schulze.
- New argument to: @timecall: immediate (defaults to False).
- Added a test suite.
- First release to PyPI, with a setup.py and everything.
- New arguments to @profile: dirs, sort, entries. Contributed by Hanno Schlichting.
- Preserve function attributes such as __doc__ and __module__ when decorating them.
- Pydoc-friendly docstring wrapping and other docstring improvements.
- Changed licence from GPL to MIT.
- New decorator: @timecall
- New arguments to @profile: skip, filename, immediate.
- Added support for profile, after becoming convinced hotshot was unreliable. Made it the default profiler.
- First public release (it didn’t actually have a version number), announced on my blog: http://mg.pov.lt/blog/profiling.html
- @profile and @coverage decorators that didn’t accept any arguments.
- hotshot was the only profiler supported for @profile, while @coverage used trace.py
