Modules

ast

AST types shared by all diagram kinds.

Structs

DiagramMeta

Shared, diagram-agnostic metadata extracted from the source preamble (YAML frontmatter, %%{init}%% directives, and accTitle/accDescr statements) before dispatching to a per-diagram parser.

Theme

Enums

Diagram

ParseError

RenderError

SyntaxKind

The class of a ParseError::Syntax failure. Lets callers distinguish the recurring kinds of parse error (unknown statement vs bad number vs unclosed block) without inspecting the free-form message.

Functions

parse

parse_with_meta

Parse input, also returning the cross-cutting DiagramMeta (title, accTitle/accDescr, theme) extracted from the source preamble. The diagram body is parsed from the source with the preamble removed.
