How to use the built in markdown parser

[bernhard]

$format = $modules->get("TextformatterMarkdownExtra");
$format->format($str);
echo $str;

Nice one, thanks! When I saw the post title, being in Tuts, I was expecting one of your long posts ?. This works fine though; simple and to the point!

I think I have never ever used any of the recipes - if anybody uses that as source of such snippets feel free to post it there. My screenshot is licensed under MIT ?

You can also use $sanitizer->entitiesMarkdown(), either for basic markdown or full markdown by setting the options argument to true.

@bernhard - Where does d() come from? In my ProcessWire 3.0.165 (production) I get:

$str = "| Entry |
| Foo |";
$md = $modules->get('TextformatterMarkdownExtra');
$md->format($str);
d($str);
// Fatal Error: Uncaught Error: Call to undefined function d()

// Same for:
d('foo');

d() is the dumping feature of Tracy Debugger ? 

Use it in the tracy console code panel and you'll be a lot faster with such quick php snippet tests/creations ?

This textformatter seems to work for really simple Markdown things like emphasis  and headers. But I get Trying to access array offset on value of type null errors if I do any of the following:

• create an unordered list by beginning successive lines with `- `
• feed it text that contains a bracket character (`[`) that’s not being used as part of a link
• put a short string of `-` characters on a line of its own to generate a horizontal rule

Interestingly, if I try to create an unordered list by beginning successive lines with `• ` instead of `- ` (both are acceptable Markdown syntaxes), the attempt is just ignored: no formatting is done and no error occurs.

Also interestingly, ordered lists work as expected!

Are others encountering these problems? I really want to be able to parse Markdown. I’d love for extended things like footnotes and tables to be supported, but I’d settle for Gruber’s original bare-bone syntax.

It's working for me.

I'm using PHP 7.3 so if you are using a newer version then it could be that the included Parsedown library needs an update. If you trace it back to being related to PHP version then please open a GitHub issue because TextformatterMarkdownExtra is a core module.

Wow — not what I see at all. Thanks for testing, @Robin S! I’ll look further into this and report back. I’m using PHP 7.4, btw.
