HOWTO: Programmatically pre-index?

[MaskRay]

ccls starts indexing the whole project (with compile_commands.json or hierarchical .ccls) after it received the initialize request telling it where the project resides. When you open the first file in your editor, the indexer threads are working in the background, while the main thread is serving requests from the language client plugin.

If you want to have headless indexing, you may use some specialized language client to just send an initialize request then wait.

I'd like to precompile

This is usually unnecessary because the main thread can still serve requests before the indexing is finished. The index will also be updated automatically when you save a file in your editor (textDocument/didSave triggers re-indexing of that file).

Also I'm not sure how dereferencing would work adhoc.

Sorry I don't understand your question.

I had thought dereferencing type definitions required a global view of the codebase in order to be accurate. Is that not the case?

Will initialize return when indexing is complete?

[MaskRay]

`initialize` spawns several indexer threads abd returns. The main thread does not wait for completion. Yes, many operations require global view if the code base.

I have added some description to README.md

It starts indexing the whole project (including subprojects if exist) parallelly when you open the first file, while the main thread can serve requests before the indexing is complete.
Saving files will incrementally update the index.
