[pmwiki-users] Macros for PmWiki?

[Petko Yotov]

We have something like this, we call it include a section (template) 
with variables, see

   https://www.pmwiki.org/wiki/PmWiki/IncludeOtherPages#includevariable

For example, you can have a hidden section [[#macro]] in the page like 
this:

(:if false:)
[[#macro]]
{$$fname}\\
(:video {$$fname}.mp4 poster={$$fname}.jpg:)
[[#macroend]]
(:ifend:)

Then to insert the macro you include it:

(:include #macro fname=MyVideo:)

(:include #macro fname=OtherVideo:)

(:include #macro fname=ThirdVideo:)

The markup in the template can be more complex, you can have more 
variables.

The template can also be a separate page, especially if it is included 
from more than one page.

   (:include Page fname=MyVideo date="May 3, 2020" size=8mb:)

The template section may contain markup expressions, wikistyles or any 
other markup (except anchors*). I'd probably try for the caption:

   {(asspaced "{$$fname}")}

which would output "My Video" instead of "MyVideo"

See also $MaxIncludes in the documentation.

*) You can have anchors in the included section but then the directive 
needs to specify both the first and the last anchors like (:include 
page#anchor#anchorend:)
