fix: yaml-ls initialization and bootstrap environment issues

Open processtrader opened this issue 1 week ago • 3 comments

This PR fixes the yaml-ls language server which was failing to initialize due to incorrect executable paths and restrictive root detection.

YAML LSP (yaml-ls)

Provisioning Strategy: Switched from hardcoded JS paths to bun x yaml-language-server --stdio. This ensures the server works reliably by using the package manager to resolve the binary, avoiding "file not found" errors caused by version-specific path changes in node_modules.
Root Detection: Added support for common YAML project files (.yamllint, kustomization.yaml, docker-compose.yaml) to correctly identify workspace roots in non-Node.js projects.
Default Configuration: Enabled completion, hover, validation, and schemaStore by default in the server initialization options.

Verified that yaml-ls now correctly identifies syntax errors and provides schema-based diagnostics.
Verified that the server spawns correctly using bun x.
