  • Added logic to walk through workspace folders and initialize templ files.
  • Logs warnings when source maps are not found in cache.
  • Parses templates and sets source map cache contents.
  • Handles errors during file reading, template parsing, and generation.

This PR preloads the templ files into sourcemaps

This works, but the issue still persists, will need to look closer as to why

Okay, so before the file is open, when we forward the request to gopls, it returns a result that is off by 1 (in the line only, character is fine)

This throws our mapping off. I have no idea why that would be the case at the moment

- Added a global variable `preLoadURIs` to store URIs to be preloaded.
- Modified `Initialize` method to append URIs to `preLoadURIs`.
- Updated `Initialized` method to preload URIs by calling `DidOpen`.
- Ensured `DidOpenTextDocumentParams` are created and appended correctly.

Okay, this works.

We store the loaded URIs and their contents and then fire them into didOpen once the servers are all initialized.

I don't know if I like this implementation, but it works.

If anyone has a moment, can they give a pre-review and any thoughts on how it can be improved?

Moved the preLoadURIs variable from a package-level variable to a field
within the Server struct

I'm going to take some time to test this out today in various projects to ensure it works as expected.

I also wonder if we can lock this bug away with an lsp test: https://github.com/a-h/templ/blob/60631f964f1c347f3ef5ff34caab3e01b968855c/cmd/templ/lspcmd/lsp_test.go

Happy to add this changes if you don't have time, let me know! And thankyou for the contribution and deep dive into this bug!

- Add new test cases in `TestReferences` to handle references from remote
  files that have not been opened.
- Introduce `remoteChild.templ` and `remoteParent.templ` files for testing
  remote inclusions.
- Update existing test cases to include filename in the test struct.

I have added a test (and fixtures to provide for this) have a look and see if you think this is good enough
