[asciidoc-lang-dev] [ANN] AsciiDoc implementation that can be used as a

[Guillem Marpons <gmarpons@xxxxxxxxxxx>]

Hi!

The last months I've been slowly working on an AsciiDoc parser in 
Haskell that can be used as a Pandoc front-end:

  https://github.com/gmarpons/asciidoc-hs

It's still not ready for real use (a lot of AsciiDoc features are 
missing), but I think the foundations for easily adding new features are 
laid out.

I've written a blog post about my goals, difficulties found, and 
solutions provided so far that I think it might be of interest to the 
members of this list:

I don't want to short-circuit the spec project plan and I'll try to 
contribute to it in the next weeks, but I thought that the release of my 
project and blog post were relevant enough to share here.

I believe that the main technical innovation of the project is that 
there is an independent inline parser based on a formal (yet eclectic) 
grammar that can handle constrained/unconstrained formatting. The 
grammar is simple enough to be:

  1. Easily augmented with new features
  2. Useful in taking decisions about precedence (disambiguation)
  3. Useful to prove different properties about the parser (e.g., that 
any character can be processed at any point in the input).

The description of the grammar can be found here:

Any feedback and contributions to the project are very welcome!
