Re: [NTG-context] Mark IV Syntax highlighting support
Hi folks !
I have just finished a first draft of pret-xml.lua:
- I need to improve its coverage (html);
- DTD declaration is not yet managed;
- I do nothing about re-indentation since I prefer to format my xml
sample by myself (by hand or using xmllint);
- That's my first try to lua/luatex (after several months of Java...) so
my definitions (esp. for functions) is not clean at all (you have been
warned);
I have done it the trial/error way without much design reflexion just
for fun (I'm on vacation)... I'm not sure it will be reusable...
Take all your test files and please report issues (or give me advices)! ;)
Thank you Matthijs!
Regards,
Renaud

Hey all,
./tex/texmf-context/tex/context/base/verb-.*\.lua !
Actually, in newer versions (since a month or so), that's pret-*.lua.
Where to start with this topic (current state in Mark IV, roadmap, ...) ?
I've been struggling with this a bit as well lately and found there was next
to no documentation. I've managed to create my own pretty printer, and tried
to update the docs a bit. See [1] and [2] on the wiki for more info. There are
still some details I don't get (why is there a line() hook, what is all this
nesting stuff, etc.), so feel free to find out more and improve these pages!
