[Bug]: ALS struck when project/file path contain space

[Heziode]

Environment

• OS and Version: macos 15.7.3 (24G419)
• IDE Version: Claude Code 2.1.5
• Ada & SPARK Extension Version: N/A

Bug Summary and Reproducer

Bug Summary:
I creating the Ada LSP plugin for Claude Code. But when testing it, it appears that ALS seems stuck on project or files when its path contains spaces.

Steps to reproduce:
Run queries on a project that contains space in the path (eg: /Users/heziode/Awesome Projects/my-project

Expected behavior:
ALS answer the request.

Okey, it is related to anthropics/claude-code#17856

Hello,

I think the standard for URI syntax requires that space must be encoded as %20.

What are you using to produce the LSP messages on the client side? If that code is under your control, can you try encoding spaces? Ideally it's best to use an existing library that already implements URI encoding.

Yep, u're right. Space in URI SHALL BE encoded, as described in the RFC.

Unfortunatly, I have no control on the URI sends to ALS. It's managed by Claude Code.

In fact, the Claude Code plugin for Ada LSP it's just a JSON file (.lsp.json file).
I guess Claude Code client is not following the RFC (not using a URI lib) to encode the URL before sending it to the LSP.

In my previous message, I linked an issue on Claude Code repository (it's not FOSS, it's only for bug report) where someone had this exact same bug with another LSP.

The question raised should be: does LSP should managed malformed / not fully compliant URI, or should it return an error?

Hi @Heziode,

We can return an error indeed. We'll create an internal issue for this enhancement.
