I do not know if it works on Pharo, but XTreams has a XTreams-Parsing section that I am currently working with. The existing Wikitext grammar was my starting point .

https://github.com/squeak-smalltalk/squeak-ci/blob/master/package-load-scripts/Xtreams.st

the existing Grammar is under:

XTreams-Parsing -> PEGParser > grammars->grammarWiki

Use case is:

| wikiGrammar wikiParser output|
Transcript clear.
wikiGrammar := PEGParser grammarWiki reading positioning.
wikiParser := PEGParser parserPEG parse: 'Grammar' stream: wikiGrammar actor: PEGParserParser new.
input := (your string input goes here)
output := wikiParser parse: 'Page' stream: input actor: PEGWikiGenerator new.
output inspect.

Hi guys - do we have a simple markdown parser that is reasonably up to date? I did a quick GitHub scan and a few popped out, but I wasn��t convinced I had found one the ��everyone�� uses (albeit, everyone might be a small sample).

Ideally I don��t want to get sucked into writing another one (a project for a future time).
