Write Dokuwiki headings with hash character “#”. For example: ##heading2.

HashHeadings syntax was inspired by MarkDown.

HashHeadings is a Dokuwiki syntax plugin, tested with Dokuwiki 2007-06-26b.tgz (local mirror).

HashHeadings makes it faster and easier to type wiki syntax. Let’s compare!

HashHeadings syntax:

# Level 1 Headline
## Level 2 Headline

Original Dokuwiki syntax:

====== Level 1 Headline ======
===== Level 2 Headline =====

I think it’s easy to count to one or two. However, original Dokuwiki syntax makes you count (7-1) or (7-2) twice.
