Disabling parser rules

[silverpill]

Is it possible to skip parsing of certain elements, such as headings or lists?
In my application I need to support only a subset of GFM. The workaround I'm currently using is re-rendering of certain AST nodes back to markdown and replacing them with text nodes, but perhaps there's a better way?

There is no such feature at present, though I imagine it might not be too hard to add checks at key places in the parser where certain elements are recognised. Pull requests welcome!

converted this issue into discussion

I'm still interested in this.

I imagine that instead of re-rendering back to markdown (lossy), one can use sourcepos to get the original text, but when I tried to do that I found that some sourcepos have unexpected values. Don't remember what exactly was wrong, maybe positions were set to zeros
