Module LanguageFeature 

LanguageFeature (Tauri command surface)

Bridges Monaco-Editor language requests from Sky into the Mountain LanguageFeatureProvider registry. Six wire-bound commands, each in its own file (file name = Tauri command identifier per the Naming-Convention exception):

• MountainProvideHover::MountainProvideHover
• MountainProvideCodeActions::MountainProvideCodeActions
• MountainProvideDocumentHighlights::MountainProvideDocumentHighlights
• MountainProvideCompletions::MountainProvideCompletions
• MountainProvideDefinition::MountainProvideDefinition
• MountainProvideReferences::MountainProvideReferences

Each command is a thin shell that validates input and delegates to the matching provide_*_impl in the sibling Hover / CodeActions / … modules. Implementation files are pub(crate) because callers outside this directory should go through the wire-bound shells.

Errors propagate as Result<Value, String> with the string sent straight to the frontend; provider errors (CommonError) are stringified at the boundary.

VS Code reference: vs/workbench/api/common/extHostLanguageFeatures.ts, vs/workbench/services/languageFeatures/common/languageFeaturesService.ts.

Planned Work

• Document symbols, formatting, rename, signature help
• Semantic tokens, code lens, inlay hints
• Linked editing range, call/type hierarchy
• Document color, folding/selection range
• Request dedupe and cancellation tokens for long-running ops
