Subject: bug#46274: 28.0.50; Inconsistent doc for syntax-propertize-function
Date: Wed, 03 Feb 2021 23:04:26 +0300 [thread overview]
Message-ID: <m28s84ex4l.fsf@fastmail.fm> (raw)
C-h v syntax-propertize-function contains this text:
--8<---------------cut here---------------start------------->8---
The specified function may call `syntax-ppss' on any position
before END, but if it calls `syntax-ppss' on some
position and later modifies the buffer on some earlier position,
then it is its responsibility to call `syntax-ppss-flush-cache' to flush
the now obsolete ppss info from the cache.
--8<---------------cut here---------------end--------------->8---
But (info "(elisp) Syntax Properties") has a different view:
--8<---------------cut here---------------start------------->8---
It is allowed to call ‘syntax-ppss’ on any position before END.
However, it should not call ‘syntax-ppss-flush-cache’; so, it is not
allowed to call ‘syntax-ppss’ on some position and later modify the
buffer at an earlier position.
--8<---------------cut here---------------end--------------->8---
Which is the right one?
Thanks.
