Herve Boutemy commented on DOXIA-617:
-------------------------------------
one stupid question: i did not even know that we supported header without
hyphens
we never define such headers: see maven-site-plugin tests
[https://github.com/apache/maven-site-plugin/tree/master/src/it/projects/doxia-formats/src/site/markdown]
or Maven Site
[https://github.com/apache/maven-site/tree/master/content/markdown]
I'm not again adding support for such hyphens
but I'd like that we precise what's the result of defining such headers (or not)
Notice: while working on DOXIA-569, I was wondering how we could render such
headers, so now I'm pleased to see that there is a format, i just need to use
it (hoping that it has the same results than apt or xdoc...)
> doxia-module-markdown: Add support for --- header section marks
> ---------------------------------------------------------------
>
> Key: DOXIA-617
> URL: https://issues.apache.org/jira/browse/DOXIA-617
> Project: Maven Doxia
> Issue Type: Improvement
> Components: Module - Markdown
> Reporter: Bertrand Martin
> Priority: Major
>
> h1. Use Case
> It is "generally" accepted that document header metadata in Markdown (like
> _title_, _author_, etc.) must be specified inside a header section, delimited
> with 3 hypens:
> {noformat}
> ---
> title: My Doc Title
> author: Myself
> keywords: great,doc
> ---
> # Introduction
> ...
> {noformat}
> See:
> * https://bookdown.org/yihui/rmarkdown/html-document.html
> * https://pandoc.org/MANUAL.html#extension-yaml_metadata_block
> * https://github.com/vsch/flexmark-java/wiki/Extensions#yaml-front-matter
> Currently, the only supported syntax for document header metadata is the very
> same as above, but *without* the 3 hypens marking the header section:
> {noformat}
> title: My Doc Title
> author: Myself
> keywords: great,doc
> # Introduction
> ...
> {noformat}
> h1. Specification
> Enable the YAML Front Matter Extension of Flexmark so that such header is
> processed automatically (nothing to code here!)
> Keep the default behavior (we want backward compatibility) with the parsing
> of metadatas (which won't be affected by the YAML Front Matter parsing).
> h1. Doc
> Update the documentation on how to use Markdown in Doxia. This feature
> (document metadata) is currently not documented.
> We should have a small guide on how to use Markdown in Doxia, and its
> specific features (metadatas, macros, etc.)
> h1. Test
> Add corresponding unit tests and integration tests (for both old and new
> syntaxes)
