New submission from Guido van Rossum <gu...@python.org>:
Pgen is literally the oldest piece of technology in the CPython repo -- it was the first thing I wrote for Python over 29 years ago. It's not aged well, and building it requires various #if[n]def PGEN hacks in other parts of the code; it also depends more and more on CPython internals. There already is a replacement written in pure Python (Lib/lib2to3/pgen/), it just needs some glue to actually generate the graminit.[ch] files. Note that several other essential generation steps (everything listed for regen-all except regen-importlib and clinic) already depend on having a working Python interpreter around, so let's not worry about the bootstrapping process. ---------- components: Build messages: 334247 nosy: gvanrossum priority: low severity: normal stage: needs patch status: open title: Let's retire pgen versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35808> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
