Sorry about that :-( +Eric Liu <ioeric at google.com> who may have thoughts.
I don't think we have an option to disable includes today, maybe we should
But we don't expect the inserted includes to create compile errors - *this
is probably a bug, it'd be great if you could provide more details* (is it
the right header but spelled wrong, or the wrong header entirely, etc). It
may be that you'd like this feature if it worked properly.
For turning this off, there are a few cases to consider.
Completions come from the current AST and clangd's index, header insertions
always comes from clangd's index.
A) the suggestion comes from the AST, not the index
B) the suggestion comes from both the AST and the index, and the suggested
header is already directly included
C) the suggestion comes from both the AST and the index, and the suggested
header is not directly included
D) the suggestion comes from the index only, and the suggested header is
E) the suggestion comes from the index only, and the suggested header is
not directly included
Currently we insert #includes in cases C and E.
Possible alternative behaviors (that could be controlled by a flag, or be
- never insert. Allows completions of type E to break the code if the
header is not transitively included.
- never insert, and disallow completions of type E. This will lose a lot
of essential completions.
- insert in case E only. In case C, the code will still compile. This is
somewhat a style question (include-what-you-use), but has some other subtle
implications (e.g. for completions of incomplete class types).
