Replace language for wikifs -Diff-

---

---

The wikifs(4) in both Plan 9 and Inferno understand a very small set of cues when generating HTML. That set can be limiting. It should be replaced with something better, like Markdown.

Markdown engines in C already exist, and have been ported to Plan 9 via APE. For proper integration this should likely be turned into a native parser, but that should be a relatively easy task.

Doing this for the Inferno wikifs would be a bit more work, as no Markdown implementation exists in Limbo today (although there are similar things).

These two together should make a good summer-sized project. Any extra time could be spent converting the existing pages (or, even better, writing a conversion program).

It is not particularly important that the language understood by wikifs be markdown, per se, but it would be very nice if it was one of the widely understood similar alternatives (rather than a new creation). It is more important that the language understood by the Plan 9 and Inferno wikifs implementaitons be the same (or, at the very minimum, one a proper subset of the other).

Discount, a Markdown implementation with Plan 9 support (via APE) in the mainline tree.

textmangle, a Limbo implementation of a markdown-like library (with moderately different syntax).

Pandoc and MultiMarkdown are two possible extensions worth considering. There are lots of others.

Textile and reStructuredText are alternatives to Markdown which might be suitable, although neither is in as widespread use.
