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!

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)! ;)

syntax highlighting is kind of tricky esp since we can have either correct syntax or faulty (can be educational) this is why the pretty printers work in a rather dumb non validating mode; however, in mkii we also have parser based variants for xml pretty printing in mkiv i will provide only a few pretty printers, i.e. the ones needed for my manuals; these will be organized under pre-* in addition i will provide a user installable variant but i need to think about it a bit; we also need more verbose names then so that there can be multiple pretty printers per file type; (i will also make a basic configureable mapper but that's for later) so, we can have both validating and non validating pretty printing and multiple variants in any case .. keep making and testing them .. i'll try to cook up the plug in mechanism and naming scheme asap Hans ps. dtd declaration etc ... i shall provide a pretty printer based on th ebuild in xml parser (kind of like what we have in mkii); of course this leaves along non validated coloring ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
