Crate mos_eval 

Expression and scripting evaluator (manifest §4, §25).

The “evaluator” is really a lowerer + resolver: it walks a [SyntaxTree] from mos-parse and builds the typed semantic [Document] graph from mos-core (manifest §6 stage 2), then runs the resolve pass to assign section numbers and rewrite @label cross-references (§6 stage 3, MVP 1).

Modules

suggest 🔒

Conservative nearest-match selection for “did you mean” diagnostics.

Structs

DocumentMetadata

Document-level metadata harvested from #set document(...) directives.

EvaluationState 🔒

Evaluator

Lowerer from parse syntax to semantic document graph.

LowerResult

Result of lowering a [SyntaxTree] into a [Document].

Enums

PageFixpointOutcome

The result of driving page references to a fixpoint.

Constants

DOC_ATTR

Attribute key holding a node’s attached /** … */ doc-comment text. Read by the LSP hover handler.

LABEL_SPAN_END_ATTR 🔒

LABEL_SPAN_START_ATTR 🔒

Functions

insert_label_attributes 🔒

lower

Convenience: parse + lower + resolve in one step. Concatenates the diagnostics from each stage so callers can render them uniformly.

lower_raw_block 🔒

lower_tree

Lower an already-parsed [SyntaxTree].

resolve

Run the resolver pass over document in place. Returns any diagnostics produced; the document is modified regardless of whether errors are present so partial output is still renderable.

resolve_page_reference_fixpoint

Drive page-reference resolution to a fixpoint against an injected layout.

resolve_page_references

Rewrite every @page(label) reference’s visible text.
