TUG 2006 talk
by Taco Hoekwater 07 Jun '06

07 Jun '06

Hi, I believe we should do a 'true' presentation of luatex at TUG2006. By that time we should have an alpha (or even beta) for non-developers to play with, and we need to make sure that we do not appear to be vapourware. Any comments? Taco

friday afternoon warning
by Taco Hoekwater 02 Jun '06

02 Jun '06

Hi, I want to let you know that I will definately commit my work later today, because it is friday. You may want to set aside your current work tree before running svn update. I hope to have something that is at least halfway stable before I do that, but I will not make promises. Cheers, Taco

unicode, i/o and math
by Taco Hoekwater 31 May '06

31 May '06

Hi, I have not added anything interesting to the luatex repository today, I am working on unicode support offline but will not do any commits until I can make it stop segfaulting (later this week, hopefully). You 'll be happy to know that I have created a brand new executable: luatangle This altered version of (o)tangle writes string-ids starting from twomillionninetyseventhousandonehundredandfiftytwo (2^21). It follows that the legal range of \char arguments will become 0..(2^21-1), thus allowing for all of Unicode and some spare space (2^21-1 == 0x1FFFFF; unicode only goes up to 0x10FFFF, so there will be room for almost a million non-unicode characters). As far as the core TeX-like program is concerned, all file i/o will be done in utf-8 (with one small exception: printing of the low control bytes to the terminal will use ^^X notation for dangerous byte values like ^^D and ^^Z. The internal printing code for log and terminal will be split to allow this). User-level configuration of i/o re-encoding will nevertheless still be possible, through lua callbacks that can hook directly into the i/o subroutines. No more translate-files, no more enctex, no more 8bit switches. This is all rather straightforward, because \char, \catcode, \lccode \uccode, etc. are all 'singular values'. But the math commands need attention as well. Ofte, these are a single number representing a combination of <type>+<family>+ <charnum>, and with 21bits for the <charnum> part alone, this syntax is problematic. I propose to keep the old ones (with their old, limited syntax), but also create new primitives with names like \luamathchar etc. These will read _separate_ integers, so it will look like (e.g.) \luamathchardef\dagger = 2 0 "2020 % unicode: 2020 DAGGER \def\langle{\luadelimiter 5 2 "69 3 "0B } does that make sense to you? (comments are very welcome) Greetings, Taco
