I don’t usually ponder about other people’s blog postings, but Jeff Atwood’s Responsible Open Source Code Parenting reminded me of some of the old wars that the used to be when I was a markup head. Jeff writes about his frustration that John Gruber’s Markdown text-to-html filter:
- hasn’t been updated for some time
- doesn’t quite do exactly what Jeff’s users at Stack Overflow want
- appears to have any changes in its behaviour from v1.0.1 strenuously vetoed by Gruber himself.
Markdown is nice in that you can write screeds of text, and it does almost exactly what you’d expect. The markup doesn’t get in the way, usually. The difficulty arises when implicit markup (indented lines for quoted text, bulleted lists, highlights) has to give way to explicit (cross-references, code samples). Explicit markup is ugly, but sometimes, you’ve got to do it. Complex intent requires complex modes of communication, and sometimes plain text just hasn’t the bandwidth. [As an aside, there was a hilarious lengthy recurring episode on John Mark Ockerbloom's late bookpeople mailing list where a user (mercilessly skewered here) insisted that they could write a general Gutenberg plain-text converter that would re-create typeset quality in an e-book reader with no explicit markup, and that XML was completely unnecessary and ill-conceived. The un-markup language, called zen markup language (said user had an aversion to the shift key) lives on only in a single website: the home of z.m.l. As for XML, its executive assistant had no comment on the matter.] Looking at Markdown, it looks like Gruber’s moved on from it. He made a 1.0.1 which did what he wanted. The code’s there to change if anyone needs it. I understand his frustration at people wanting to make changes and still call it Markdown; I’d be annoyed if I had text which I thought was in one format suddenly not be accepted, or do something unexpected. Seriously, that’s almost as bad as ‘deprecated‘. [At least Gruber didn't go on a deletion rampage, like (admittedly smaller-time) erstwhile CHDK stalwart Barney Fife did when he was slighted in a forum. Looks like almost everything he contributed to CHDK has been removed, including some very useful control scripts and explanations.] Personally, when I need to make text to web conversions, I still use txt2html and a bunch of shell and Perl glue to feed to tidy. It’s on its third maintainer, doesn’t do much, but does it simply. And I’m pretty simple that way.
