1 A number of static site generators and/or Markdown implementations
2 support the notion of a "front matter", a (normally) YAML list pre-
3 pended before the document text, containing document metadata. E.g.:
11 IkiWiki has (currently) made a deliberate decision not to support these (or
12 more precisely, the similar but different Pandoc-style block with lines
13 prefixed by '%'). Quoting `mdwn.pm` (here in the section that handles
16 # Disable Pandoc-style % Title, % Author, % Date
17 # Use the meta plugin instead
18 $always_flags |= Text::Markdown::Discount::MKD_NOHEADER();
20 It would be good to support YAML-formatted pre-pended metadata,
21 translating recognised keys into [[plugins/meta]] definitions, to aid
22 migration between IkiWiki and other static site generators: it
23 would aid the same source files being useable in multiple systems.
25 This would require the `mdwn` plugin to be more closely-coupled to
26 the `meta` plugin, but not the reverse. I think this wouldn't be a
27 big problem, as the prospect of an IkiWiki site that was using the
28 `mdwn` plugin but *not* the `meta` plugin is fairly remote. And we
29 could make front-matter handling configurably on or off.
