It's mostly for using cProfile on a whole script. Since line_profiler is already only active for certain functions, it's probably not all that useful. At the time I added the feature, I was trying to profile (part of) a GUI program using wx and VTK, both of which take a long time to load and taking up a good chunk of my profile time. If I had a script, load_wx_vtk.py: import wx from enthought.tvtk import tvtk Then I could just do: $ kernprof.py -s load_wx_vtk.py my_script.py The script at the end still needs to be the main thing that executes. > I ended in doing a %edit in ipython to write a small > test script with testdata and library imports, used kernprof.py and > view_line_prof.py from ipython and captured the output from view_line_prof > into ipython. Pheew .... now, there's perhaps an easier way? It should be straightforward to make an ipython %magic, yes. There are some questions as to how that would work, though. Do you want the top-level code in the file to be profiled? Or do you just want functions defined inside to be profiled? Do you want to be able to specify functions defined outside of the code to be profiled? > BTW, in the requirements you may want to mention argparse > (view_line_prof.py) Oops!
