[ANN] ClothRed (HTML to Textile

Phillip Gawlowski

4/10/2007 5:39:00 PM

I'm pleased to announce, that I've begun working on a small library to
convert HTML into Textile.

Please forgive me, that this announcement isn't yet following the
community's standards, but I'm slowly getting there.

For the curious, the website and project on RuybForge have gone online
*and* have some content[0].

For the impatient:
ClothRed will be exactly the reverse of RedCloth: It will grab any HTML
string, and convert it into Textile.

As a bonus, ClothRed will strip all HTML that is not being converted
into Textile's markup from the text, making it, hopefully, usable for
sanitizing HTML.

I hope to have an Alpha release out by the end of next month.

Awesome, Phillip. I really look forward to using this!

Looks interesting, but I hope there would be a mode to preserve unknown
HTML in addition to the "lossy" mode. Sanitizing HTML is good but if you
convert the resulting Textile to HTML and it doesn't look like the
original, that's not too good IMHO.

To do that, there'll probably be two different modes of HTML stripping:
* One "strict": Every thing that cannot be parsed by ClothRed will be
thrown out.
* One "loose": All HTML that ClothRed cannot preserve will be kept, and
warnings will be emitted (either to stdout, or stderr, or both).

The latter will not be usable for sanitizing HTML, as "unknown" HTML
*should* be treated as malicious (specifically, as there is no "unknown"
HTML in the W3C specs).
