Somwhere thers a transition pandoc meta -> general meta, for some meta
# Pagestate data
This is for *arg-for-fripost*
* 002 1 early
* Meta according to wiki tags: title, titlesort
* No tags seen at all
* 002 4 return
* most 'pandoc_*' available
* meta 'tag' and 'pandoc_tag' set according to pandoc meta
* meta 'abstract' and 'pandoc_abstract' empty
* meta 'num_authors' is 2, 'author' content as string,
'pandoc_author' content as list
* 007 1 early
* Meta overwritten according to wiki tags: title, titlesort, author, etc
* Otherwise unchanged from 002 4
* 007 4 return
* Back to 002 4
* 013 1 early
* Back to 007 1
* 013 4--027 4 continues
# Working template variables
The sytanx is e.g. `<TMPL_VAR TITLE>`. Compare template
*nonempty.tmpl* with resulting HTML:
* TITLE -- pandoc meta
* DATE -- fallback to default `<TMPL_VAR DATE DEFAULT="1970-01-01">`
* TITLESORT -- nothing
* AUTHOR -- pandoc meta, 002 4, content as string
* ABSTRACT -- noting
* PANDOC_DATE -- pandoc meta
* PANDOC_PRIMARY_AUTHOR -- pandoc meta
* NUM_AUTHORS -- nothing
* TAG -- nothing
* PANDOC_TAG -- pandoc meta
* PANDOC_TITLESORT -- pandoc meta
* PANDOC_ABSTRACT -- nothing
* PANDOC_TITLE -- pandoc meta
* tags again with loop: ikiwiki meta
tags again with loop:
```
<TMPL_IF TAGS>

<TMPL_LOOP TAGS>
<TMPL_VAR LINK>|
</TMPL_LOOP>
</TMPL_IF>

```
# Page template data
This is for *arg-for-fripost*
* identifies
There is a need to also put things in subroutine *pagetemplate* to make
them available as variables:
```
foreach my $k (keys %{$pagestate{$page}{meta}}) {
next unless $k =~ /^(pandoc_|fripost_)/;
$template->param($k => $pagestate{$page}{meta}{$k});
}
$template->param('date' => $pagestate{$page}{meta}{date});
```
Things that comes populated in page template data (*pagetemplate*)
that are not available in page state data (*htmlize*) include the
following:
* tags
* parent links
Parent links as `$template->{param_map}->{parentlinks}` (loopable) and
`$template->{param_map}->{has_parentlinks}` (variable bolean). The
loop scope makes *page* and *url* available.
Tags as `$template->{param_map}->{tags}` (loopable). The loop scope
makes *link* available.
# Between title and sort in htmlize
Author fields filled forcefully. Title fields not.
# Structure of various meta variables
It is clear that scalar (*MetaInline*) are added and some list
elements (*MetaList*). Most list, plain, and maps are not. Read code
around "Try to add other keys as scalars, with pandoc_ prefix only."
Inspect *content look for type (`t`) of meta block elements.
