This is a tool to simply parse a file as clangd would, and run some
common features (code actions, go-to-definition, hover) in an attempt to
trigger or reproduce crashes, error diagnostics, etc.
This is easier and more predictable than loading the file in clangd, because:
- there's no editor/plugin variation to worry about
- there's no accidental variation of user behavior or other extraneous requests
- we trigger features at every token, rather than guessing
- everything is synchronoous, logs are easier to reason about
- it's easier to (get users to) capture logs when running on the command-line
This is a fairly lightweight variant of this idea.
We could do a lot more with it, and maybe we should.
But I can't in the near future, and experience will tell us if we made
the right tradeoffs and if it's worth investing further.
