markdown-it-when

Conditional text render plugin for markdown-it markdown parser

With this plugin you can create conditional text blocks and inline parts that are rendered only when (that's where the name comes from) the condition is met.

Here be ((when dragons))*dragons* or ((/when))other creatures.

((when dragons))
And here, too.
((/when))

Now you can override when_open, when_close, when_block_open and when_block_close blocks and inline blocks to achieve something like this in, for example, Vue:

Here be <span v-if="dragons"><em>dragons</em> or </span>other creatures.

<p v-if="dragons">
And here, too.
</p>
