Implement Markdown helper about yii2 HOT 22 CLOSED

I think it should support github style markdown as well.

from yii2.

Should at least be easily extendable to parse additional syntax like username highlighting or issues numbers, or whatever the like.

from yii2.

Well, current one in 1.1 is extensible enough.

Autoloading looks a bit ugly.

from yii2.

Done but should be improved:

1. Code highlighting.
2. Github flavor support.

from yii2.

I prefer syntax highlighter to be serverside. Found these options so far:

• https://github.com/markwatkinson/luminous
• http://qbnz.com/highlighter/
• http://pear.php.net/package/Text_Highlighter/ (used in 1.1, not maintained anymore)
• http://fshl.kukulich.cz/
• https://github.com/ccampbell/nijikodo

from yii2.

I like code highlighter used on www.yiiframework.com

from yii2.

@yiidevelop that's the one from Pear and isn't maintained anymore.

from yii2.

@samdark yea, Pear use code syntax php old version, implement very difficult

from yii2.

@qiangxue DocComment on Yii2 class object as MarkDown syntax?
ex: [[ABC]] not found on markdown default

from yii2.

@yiidevelop Markdown + additional syntax for linking to classes, methods and properties.

from yii2.

@samdark Thanks for implement MarkdownHelper
Do you have any plans to convert from html to markdown text?
If someone does find a vendor php do this, please share.
Thank advanced

from yii2.

No, no plans for reverse conversion.

from yii2.

Another highlighting option: https://github.com/scrivo/highlight.php Original JS code is quite good so if port is accurate I'd use it.

from yii2.

I have found today this markdown parser https://github.com/kzykhys/Ciconia
it is already bundled with Github Flavored Markdown support
and has clear Extesions system, looks very promising (as with php-markdown looks very hard to extend, atleast parsing code not very clear for me).

from yii2.

Have made some test of Ciconia
Some visual rendering comparison here http://i.imm.io/1k8Z5.jpeg
Plus is that Ciconia really support some minor GFM things addtionally, liek checkboxes (but it is not so commonly needed).
Great plus is that if is very easy to extend - I was able to add basic Mustache-like syntax parser with custom plugin

    public function processWidget(Text $text)
    {
        $text->replace('/{\s*([^}]+)\s*}/', function (Text $w, Text $name) {
            return $w->replaceString("{{$name}}","RENDER $name RENDER");
        });
    }

so anyone will be able to add any simple snippets-widgets (in any case Markdown is mostly pre-rendered and cached on save to DB), so it depends only on regex you will use.

Minus (quite significant) is memory, speed and dependency on some Symfony components. As we can see for the same text

php-markdown
Memory usage: 334.8046875 Kb
Time taken : 1.1970820426941 sec

Ciconia
Memory usage: 839.6796875 Kb
Time taken : 4.6268730163574 sec

from yii2.

Quite significant speed difference...

from yii2.

Currently working with https://github.com/erusev/parsedown which is the fastest from the benchmark. I also really like what I see in the code. It currently is not extendable at all but I sent some pull requests and also got positive feedback. Imo this one is a really good choice as it support GFM out of the box and will be highly extendable when my PRs are merged.

from yii2.

Reviewed some existing markdown implementations and decided to start my own: https://github.com/cebe/markdown
All existing implementations are either slow or not extensible so I decided to combine these two factors in a new implementation. It already parses the original markdown very well. Will extend it with MarkdownExtra and GFM soon.

Please help testing it and send bug reports: https://github.com/cebe/markdown/issues

I am going to integrate this with Yii 2 when it is stable enough and will maintain a release at least as stable as yii2 will be.

from yii2.

@cebe Sorry for resurrecting an old issue, but I see you've had a bunch of pull requests merged over on the parsedown repo. Any plans of including parsedown as an official flavor in BaseMarkdown?

from yii2.

@takobell we could consider it but please open a new issue for that.
