|
|
* Markdown processing in Javascript done right. We have very particular views
|
|
* on what constitutes 'right' which include:
|
|
*
|
|
* - produces well-formed HTML (this means that em and strong nesting is
|
|
* important)
|
|
*
|
|
* - has an intermediate representation to allow processing of parsed data (We
|
|
* in fact have two, both as [JsonML]: a markdown tree and an HTML tree).
|
|
*
|
|
* - is easily extensible to add new dialects without having to rewrite the
|
|
* entire parsing mechanics
|
|
*
|
|
* - has a good test suite
|
|
*
|
|
* This implementation fulfills all of these (except that the test suite could
|
|
* do with expanding to automatically run all the fixtures from other Markdown
|
|
* implementations.)
|
|
*
|
|
* ##### Intermediate Representation
|
|
*
|
|
* *TODO* Talk about this :) Its JsonML, but document the node names we use.
