Subject: bug#37849: composable character alternatives in rx
Date: Sun, 27 Oct 2019 10:17:40 +0100 [thread overview]
Message-ID: <D00B09DC-49AB-4587-BA44-A05D17E55A52@acm.org> (raw)

Expansion inside (not ...) should be uncontroversial; now pushed (cbd439e785).
Character set operators (union, intersection, difference) would be useful. Consider:
(rx-define ident-chars (any "a-zA-Z0-9"))
(rx-define operator-chars (any ?+ ?- ?* ?/ ?< ?> ?=))
There is then currently no way to form the set of characters that excludes both the above sets.
