Debugging and Profiling

Debugging

  1. Install LiClipse ( liclipse.com ) – no need to install Eclipse first
  2. Start debug server as described here: http://www.pydev.org/manual_adv_remote_debugger.html
    • follow the “Note:” to enable the debug server menu item
  3. Create a file named DEBUG next to inkstitch.py in your inkstitch directory
  4. Run any extension and PyDev will start debugging.

Furthermore it will generate SVG files for debugging.

Profiling

Create an empty file named PROFILE next to inkstitch.py in your inkstitch directory. Ink/Stitch will then run under a profiler and dump the result to profile_stats. It will tell you what functions take how long to run.

Install snakeviz with pip install snakeviz.

Open the statistics with snakeviz profile_stats.prof. This will display a really useful interactive graph in your browser.
