Module doc 

Associate .dtx documentation prose with the macro/environment it documents.

A .dtx brackets each documented entity with ltxdoc vocabulary — a macro or environment environment, or a \DescribeMacro/\DescribeEnv command — while the implementation lives in a (usually nested) macrocode block. The parser represents documentation margins as DOC_MARGIN trivia rather than DOC_COMMENT nodes, so the association is resolved in the semantic layer.

It mirrors outline: a single CST walk producing LSP-agnostic DocAssociations (byte ranges, no lsp_types), unit-testable without the language server. The ltxdoc set is static and standard, so — like the sectioning commands and \label in outline — the constructs are recognized by name rather than through a per-document signature scan.

The implementation a documented macro brackets is found structurally: the code is the macrocode/macrocode* block(s) nested inside the documenting environment, the conventional .dtx idiom. Descent stops at a nested macro/ environment so its macrocode is attributed to it, not the outer construct. \DescribeMacro/\DescribeEnv carry no nested code (the definition lives elsewhere).

Structs

DocAssociation

One documented entity: the documenting construct, the name it documents, and any code it brackets.

Enums

DocKind

Which ltxdoc construct introduced the association.

Functions

doc_associations

Collect every documentation↔code association in root, in document order.
