pgen is the parser generator, taking Grammar/Grammar as input and generating Include/graminit.h and Python/graminit.c. Only useful when you're changing Python's grammar, but without the ability to build pgen, it's hard for Windows developers to play with the grammar at all. > If running it updates a file that would trigger a rebuild, then I'd > really like it to copy what _freeze_importlib currently does as far as > writing to a temporary file and conditionally overwriting the actual > one. That is the most reliable way to avoid unnecessary rebuilds. _freeze_importlib was what I used for a guide initially, and will be again when I get around to redoing the patch :) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21107> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
