- "sudo apt-get install sloccount".
- "cp -rv SAGE_ROOT/devel/sage-main /tmp/x"
- Use a script [1] to rename all .pyx and .pxi files to .py.
- Ran "sloccount *" in the /tmp/x directory, which ignores autogenerated .c/.cpp files coming from Cython.
Here's the result for the full Sage library, which does not distinguish between Python and Cython. Note that sloccount really only counts lines of code -- comments are blank lines are ignored.
Totals grouped by language (dominant language first): python: 530370 (96.41%) ansic: 14538 (2.64%) cpp: 5188 (0.94%)
This suggests that the core Sage library is just over a "half million lines of Python and Cython source code, not counting comments and whitespace".
Here's the breakdown by module:
