Yep is a tool to profile compiled code (C/C++/Fortran) from the Python interpreter. It uses the google-perftools CPU profiler and depends on pprof (google-pprof on Debian) for visualization.

This package depends on google-perftools (package google-perftools in Debian). Once you have fulfilled these depencies you can install it with easy_install:

$ easy_install -U yep

or download the package, uncompress and execute the standard command:

$ python setup.py install

However, since the package one-file distribution, you can also just put yep.py somewhere in your $PYTHONPATH.

There are various ways to use the profiler. The simplest is add this module as argument to the Python interpreter when running your script and add flag -v to visualize the result:

$ python -m yep -v my_script.py

This will create a file my_script.py.prof that can be analyzed with pprof. Execute python -m yep to get the full list of options.

It is also possible to manually start/stop the profiler from inside Python code:

>>> import yep
>>> yep.start('file_name.prof')
>>> # do your computations
>>> yep.stop()

This will create a file_name.prof to be analized with pperf.

Visualize the result with -v will only work on UNIX. An option --prof= would also be nice.
