Module Ag_doc

module Ag_doc: sig .. end

Support for <doc text="..."> annotations:

type foo = Bar of int <doc text="This type represents foo values.">

This allows code generators to inject the documentation into the generated code.

<doc> nodes that appear in the following positions should be taken into account by code generators that care about documentation:

after the type name on the left-hand side of a type definition
after the type expression on the right-hand side of a type definition (but not after any type expression)
after record field names
after variant names

Formats:

Currently only one format called "text" is supported:

Blank lines separate paragraphs.
{{ }} can be used to enclose inline verbatim text.
{{{ }}} can be used to enclose verbatim text where whitespace is preserved.
The backslash character is used to escape special character sequences. In regular paragraph mode the special sequences are \ , {{ and {{{. In inline verbatim text, special sequences are \ and }}. In verbatim text, special sequences are \ and }}}.

Character encoding: UTF-8 is strongly recommended, if not plain ASCII.

type inline = [ `Code of string | `Text of string ]

`Text is regular text. `Code is text that was enclosed within {{ }} and should be rendered using the same fixed-width font used in all verbatim text.

type block = [ `Paragraph of inline list | `Pre of string ]

`Paragraph is a regular paragraph. `Pre is preformatted text that was enclosed within {{{ }}} and should be rendered using a fixed-width font preserving all space and newline characters.

type doc = [ `Text of block list ]

A document is a list of paragraph-like blocks.
