adding custom rules at runtime

[ciel]

I am using marked to render Markdown in an application, but I have a situation where I want to create some 'custom' renderings - similar to the way gimmicks are used in md-wiki.

I want to add some custom rules, such as the following;

[!alert:warning] > some text goes here as a warning
[!alert:success] > some text goes here as success

And have it render output like...

<blockquote class="alert warning">Some text goes here as a warning</blockquote>
<blockquote class="alert success">Some text goes here as success</blockquote>

I've seen that I can do this in marked by adding to the rules on the block literal, but this requires me to hard-code them into the actual library. Is there a way to add a rule to marked at runtime, that can allow me to leave the core library alone?

You could use the overriding methods to change the way a link is rendered depending on the link text just like md-wiki does.

I think instead of overriding an existing method, what OP wants is to define a custom rule.
e.g. All existing rules should stay the same, but maybe { some text } (or something similar) has a custom behavior.

Maybe this is relevant? #504

The focus right now is to correct for targeted specifications before revisiting extensibility.
