bpo-45866: pegen strips directory of "generated from" header (GH-29777)

2021-11-26T10:50:34+00:00

"make regen-all" now produces the same output when run from a
directory other than the source tree: when building Python out of the
source tree.

Extract visitors from the grammar nodes and call makers in the peg generator (GH-28172)

2021-09-05T13:58:52+00:00

Simplify the peg generator logic by extracting as much visitors as possible to disentangle the flow and separate concerns.

bpo-38605: Revert making 'from future import annotations' the default (GH-25490)

2021-04-21T11:41:19+00:00

This reverts commits 044a1048ca93d466965afc027b91a5a9eb9ce23c and 1be456ae9d53bb1cba2b24fc86175c282d1c2169, adapting the code to changes that happened after it.

Remove unnecessary imports in the grammar parser (GH-24904)

Fix 'gather' rules in the python parser generator (GH-22021)

2020-09-03T14:29:55+00:00

Currently, empty sequences in gather rules make the conditional for
gather rules fail as empty sequences evaluate as "False". We need to
explicitly check for "None" (the failure condition) to avoid false
negatives.
