rune-langium / core/src / RuneDslScopeProvider

Class: RuneDslScopeProvider

Defined in: packages/core/src/services/rune-dsl-scope-provider.ts:147

Custom scope provider for the Rune DSL.

Handles the 21 cross-reference patterns from the original Xtext implementation:

• Cases 1-3: Feature calls (-> and ->>)
• Cases 4-8: Operation assign root, segments, constructor keys
• Case 9-11: Switch case guards, enum values
• Case 12: Symbol references (most complex — context-dependent)
• Cases 13-21: Annotation paths, external refs, etc.

outerScope?	Scope
options?	ScopeOptions

getGlobalScope()

protected getGlobalScope(referenceType, context): Scope;

Defined in: packages/core/src/services/rune-dsl-scope-provider.ts:1355

Override global scope lookup to support import ... as <alias> resolution.

When a file contains import fpml.consolidated.shared.* as fpml, references written as fpml.Leg should resolve to fpml.consolidated.shared.Leg in the global index. We do this by building a thin alias-expansion layer on top of the regular global scope: for every qualified reference name we try to replace a known alias prefix with the full namespace prefix and retry the lookup.

Parameters

Parameter	Type
referenceType	string
context	ReferenceInfo

Returns

Scope

Overrides
