integrating context mkiv, luatex, and fmtutil, mktexlsr, etc
by Norbert Preining 03 Oct '07

03 Oct '07

Hi Hans, Taco, all! I am starting to think about integrating context/mkiv/luatex into TeX Live (and use as a test bed the Debian packages). Currently I see the following problems: - integration into fmtutil: currently we build formats for cont-en/xetex, cont-en/pdftex, etc based on the fmtutil.cnf syntax, ie calling something like $ENGINE -ini -jobname=cont-en -progname=context -8bit *cont-en.ini Now putting luatex as engine this doesn't work: (/usr/share/texmf/tex/context/base/luat-env.tex ! LuaTeX error [string "luas[0]"]:1: attempt to index global 'input' (a nil value). <argument> ...mf.instance,"luat-env.lua","tex")) } - integration into mktexlsr see my other email about multiple cache merging, but to some up: . cache should be read from more then one directory, eg from TEXMFSYSCACHE and TEXMFCACHE (with usual override stuff) . single cache updates should be possible: luatools --generate $HOME/texmf should generate the cache for $HOME/texmf in $TEXMFCACHE Other things I realized as user: - running texexec --lua test.tex generates the format in ~/luatex-cache/context/e027248d6557d124c703335e8a95ecd5/formats but it creates it again and again. - If I move the generated files from the above dir to ~/.texmf-var/web2c/luatex/ and regenerate the luatex-cache with --generate --verbose the next run does not work: LuaTools | using format name /home/norbert/luatex-cache/context/e027248d6557d124c703335e8a95ecd5/formats/cont-en.fmt LuaTools | no luc/lua with name /home/norbert/luatex-cache/context/e027248d6557d124c703335e8a95ecd5/formats/cont-en Best wishes Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining <preining(a)logic.at> Vienna University of Technology Debian Developer <preining(a)debian.org> Debian TeX Group gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- SWANAGE (pl.n.)

(better) (e) pressing your elbow on the glossop itself and working your arms slowly to the edge of the table; (f) leaving the glossop where it is but moving a plate over it and putting up with sitting at an uncomfortable angle the rest of the meal; or, if the glossop is in too exposed a position, (g) leaving it there unremarked except for the occasional humorous glance. --- Douglas Adams, The Meaning of Liff

Call for test documents
by Norbert Preining 03 Oct '07

03 Oct '07

Dear all, I am currently testing the installation of ConTeXt/MkIV on Debian and thus being in search for test documents using MkIV features/luatex stuff. Or at least document which I can/should be able to process with luatex/context. If you have any documents it would be great if you could send me them, best together with a short line on HOW to process the documents, and even better with a "correct" pdf output. This way I can do proper checking. Thanks a lot and all the best Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining <preining(a)logic.at> Vienna University of Technology Debian Developer <preining(a)debian.org> Debian TeX Group gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- THRUMSTRER (n.)

XML error reporting
by Mojca Miklavec 02 Oct '07

02 Oct '07

Hello Hans, the lua XML parser works nice: no errors are tolerated at all, so the following example: <?xml version="1.0" encoding="utf-8"?> <story> <windows>my secret</mouse> </story> will fail with a friendly message, but it would be really helpful if one would know at which line in the source file the error has happened to help debugging. Btw: \xmlprocess doesn't complain if the file is not found. I spent quite some time trying to figure out what I did wrong in the definitions again, only to figure out that the file had been saved under a different location :( None of this is high-priority, but only "would-be-nice-to-have-in-distant-future" request. Thanks a lot, Mojca

setting up context/luatex, luatex caches
by Norbert Preining 01 Oct '07

01 Oct '07

Hi all! Before uploading context 2007.09.28 I want to straigthen some things out wrt luatex etc, the least is that I want to add a README so that users can set up context/luatex themselves. Now my questions: - Is it possible to have MORE THAN ONE luatex cache directory? Something like TEXMFCACHE=/var/lib/texmf/systexmf-cache;$HOME/.texmf-var/texmfcache such that /v/l/t/systexmf-cache contains the cached trees for the system trees (/usr/share/texmf{,-texlive}, ...) $HOME/.texmf-var/texmfcache contains the cache of the users home directory texmf tree - Is it possible to tell luatools to update only some (or only one) texmf tree? Something like luatools --generate /usr/share/texmf-texlive ? - Is there an obvious objection to replace luatex binary with a script which contains the necessary TEXMFCNF settings, something like if [ -z "$TEXMFCNF" ] ; then TEXMFCNF=/usr/share/texmf/web2c export TEXMFCNF fi luatex.bin $* ? Reason: First is that we know where the texmf.cnf is and we don't have to urge the user to set the env var. Furthermore a user CAN override the TEXMFCNF settings if he wants to. Thanks a lot, and sorry for buggering you with these questions, but I want to get a decent system for Debian.

Hi, Not sure if you caught up with this yet, but Hans released a new 'current' context today. I have no time to write the release notes page today, but I believe the bulk of changes is: * a new lua lpeg-based xml and xpath parser for mkiv * a number of xetex-related fixes and changes (mostly initialized by Mojca) More tomorrow. Best wishes, Taco -------- Original Message -------- Subject: Cron <context@server> /var/www/aanhet.net/context/bin/cron/context-mirror Date: Fri, 28 Sep 2007 13:03:23 +0200 (CEST) From: root(a)aanhet.net (Cron Daemon) To: taco(a)elvenkind.com receiving file list ... done ./ context/beta/ context/current/ context/current/cont-exa.zip context/current/cont-img.zip context/current/cont-mpd.zip context/current/cont-ppc.zip context/current/cont-tmf.zip

is symb-glm still needed?
by Mojca Miklavec 21 Sep '07

21 Sep '07

Hello Hans, I figured out where spurious loading of lm-ec and lm-texnansi in XeTeX comes from. One is comming from symb-glm.tex. But, when looking at it, it seems to me that it's not even needed any more, since \leftguillemot, \rightguillemot, \guilsingleleft and \guilsingleright are defined in encodings. Esp if I'm reading the comments: "but was also one of the reasons for triggering the lm project" The only possible side effect could be the ability to use \symbol[xleftguillemot] or even more obscure usage: calling font "Guil" directly. But I doubt that anyone uses it that way, esp. since it depends on LM, and people could use any other font (it looks to me it was used the other way round, when no guilemots existed in cmr). Is it possible to supress loading of that file, at least for XeTeX where it's of no use, or at least rewriting it in some sensible way? lm-texnansi comes from meta-tex.tex. Any chance to change that piece of code, so that that font won't be needed any more (I have always wondered what that definition in meta-tex is used for)? \truefontname inside NEWTEX in font-ini seems to deliver names suitable for luaTeX, but not for XeTeX.

Hello, I took the list of binaries from texmf-macosx/bin. I'm trying to set some semi-automatic process to fetch them (well, to add them to a repository on the garden, http://minimals.contextgarden.net/) I've split the binaries into different groups. Can anyone please comment on it? a.) do we still need any of these? afm2pl afm2tfm dvipdfmx mktexmf mmafm mmpfb pfb2pfa pltotf tftopl ttf2afm ttf2tfm vftovp vptovf b.) stubs (Hans: should I simply copy everything from stubs there?) concheck ctxtools exaclient exampleg examplex exaresolve exaserver exatools imgtopdf makempy mptopdf pdftools pstopdf rlxtools rscortool rsfiltool rslibtool texexec texfont texshow textools texutil tmftools xmltools c.) simply copy from cont-tmf texmfstart luatools mtxrun d.) to be taken from texlive bibtex dvipos dvips dvitodvi kpseaccess kpsestat kpsewhich mktexlsr pdftosrc e.) latest binaries to be taken from elsewhere, whenever possible (help might be needed) dvitomp makempx mpost mpto pdftex luatex texlua (same as luatex, I guess, or simply a symbolic link?) texluac (same as luatex, I guess) xdvipdfmx xetex + pdftex.pool and xetex.pool f.) what to do with this one? xpdfsuite.zip

\buildtextaccent in LuaTeX
by Mojca Miklavec 13 Sep '07

13 Sep '07

Hello Hans, as far as I remember this used to work once back in May in LuaTeX (because I was able to fake cacute in a font which didn't have it; however it never worked in XeTeX): \definefontsynonym[bla][Iwona-Regular] \definedfont[bla] \mainlanguage[sl] \starttext čšž (\textcaron)(\textacute)\crlf \quotation{this} is {\buildtextaccent\textacute c}\crlf \quotation{this} is {\buildtextaccent\textcaron c}\crlf \stoptext Now the characters don't compose any more. What's even more interesting, it fails badly with XeTeX, where most characters are simply blank. And even more interesting - watch the different guillemots when using LuaTeX and XeTeX. Even more interesting, if you use \definefontsynonym[bla][Iwona-Regular][encoding=uc] one gets different guillemots (it might be that they're taken from LM instead of Iwona when there is no [encoding=uc] present).

XeTeX and font-selection problems
by Mojca Miklavec 12 Sep '07

12 Sep '07

Hello Hans, There's something weird going on during XeTeX's font selection: fonts : fails 1a: "lmroman12-regular:script=latn;language=dflt;+liga; +kern;mapping=tex-text;mapping=tex-text;" (nullfont) fonts : succeeds 1b: "[lmroman12-regular]:script=latn;language=dflt;+ liga;+kern;mapping=tex-text;mapping=tex-text;" ("[lmroman12-regular]:script=lat n;language=dflt;+liga;+kern;mapping=tex-text;mapping=tex-text;") fonts : fails 1a: "rm-lmr7" (nullfont) fonts : fails 1b: "[rm-lmr7]" (nullfont) fonts : fails 1a: "rm-lmr9" (nullfont) fonts : fails 1b: "[rm-lmr9]" (nullfont) which then results in systems : end file smalltest at line 13 ) stdin -> smalltest.pdf [1] ** WARNING ** Invalid CMap ** ERROR ** pdf_ref_obj(): passed invalid object. Output file removed. Output written on smalltest.pdf (1 page). Transcript written on smalltest.log. TeXExec | runtime: 10.645827 (Well, "errare humanum est: "I would understand that ConTeXt generates an error from time to time, but not that it's lying about it with "Output written on smalltest.pdf" :) It is possible, that the new version of XeTeX solves that problem (Jonathan promised to look into the problems you complained about some time ago), but I still use the version from TeX Live at the moment. It might make sense to try yet the third option without any quotes around, and generate the error if font doen't exist. Is there any chance to remove blank lines between font tests? (The log file looks really ugly now, but well ...) Mojca
