Module sections 

Extracting one section of a document, so a reader (or an agent) pays only for what it reads.

Functions

extract

The heading line whose text or anchor matches name (case-insensitive), and everything below it up to the next heading of the same or higher level.

matches

C198: the heading lines name picks. An exact heading text or {#anchor} wins over a heading that only starts with the name; a prefix match counts only when there is no exact one. More than one result means the name is ambiguous, and span refuses it.

names

The section names an error lists when a name is not found: every heading but the H1 title.

not_found

The error for a name span does not resolve: several candidates, or none. first is the file line of the body’s first line, so the lines named are file lines (C226).

outline

Heading outline: (level, text) for every heading.

span

Line range [heading, end) of the section extract would return, so writers can splice it. Headings inside fenced code are not headings.
