Previously, we didn't require that scip-ctags be available even if if you set
require_ctags
and setlanguage_map
to something likego:scip
. Instead, wesilently fell back to
universal-ctags
. This is tricky and could mask a realissue where we expect scip-ctags to be available but it isn't.
Now, we check if SCIP is needed based on
language_map
, and if so require thatscip-ctags is available.
Test plan
Lots of manual testing with various combinations of
language_map
andrequire_ctags
. Also hooked up this change tosg start
and checked indexingworks well.
