For an alternative, here a shameless plug:

Wikisyntax for the Monastery

I'm using it for 7 years now (?) and published it in 2016.

• choroba,
• Discipulus,
• FreeBeerReekingMonk
• pryrt
• GotToBTru
• and others

are regular users.

Several thousand posts were written in the meantime, only minor issues.

I wrote more than 50% of my posts from mobiles since I'm using this, HTML tags are a PITA otherwise.

"Wikisyntax" is probably misleading because it primarily supports

• autolinking of URLs
• de-localizing internal links (no lockouts) https://perlmonks.org/?node_id=11133704 becomes Re: Markdown is now supported for comments, experimentally
• short doc-links like ?my? for my
• automatic <p> tags between paragraphs
• short inline code-tags via 'single quotes'
• email-style quoting with > text...
• automated linking of Module::Names -> Module::Names

Plus: It doesn't interfere with the internal syntax:

The new syntax is translated to uppercase tags like <P> before posting and those uppercase tags are translated back again to the new syntax when editing , i.e. the <P> disappears at paragraphs end. (click on the xml display-link to see the stored format with uppercase tags)

It's based on a multi-phase regex logic and can be easily ported to Perl.

Hope this was of interest! :)
