luatex beta 0.35.0
by Taco Hoekwater 10 Mar '09

10 Mar '09

Hi, I have just uploaded luatex 0.35.0. This is a beta in the process towards 0.40.0, the version that will be included in texlive 2009. We have two big developments underway right now: * Hartmut is working on the DVI and PDF output, aiming for full support of all direction specifiers in both modes. * Taco is working on extending the math engine, aiming for complete support of the OpenType and MathML concepts. Both developments are well under way, but neither is perfect yet. The main goal of this release is to give Hans' ConTeXt mkiv code and its users a chance to catch up and test the progress so far. What's new: * The math handling portions of LuaTeX are converted to C code, and extended to support Unicode math. There are a great many related changes, see the new Math chapter in the manual for details. * A nasty bug in the paragraph breaking routine was fixed. (All lines except the first one were believed to be wider then they really were. This affected which nodes were considered as active breakpoints) * Various changes to the PDF backend to make it support non-latin directions. * Fixed the behaviour of the page offsets. Placement of the output on the physical page should now work correctly in all directions, both in DVI and PDF. There now are \pageleftoffset and \pagetopoffset primitives. * fontforge.apply_featurefile() was broken since 0.31.0 * The lua profiler library is added. * The included lua filesystem library is now 1.4.1. * Reading of pk files fixed. * An optional space afer a <direction specifier> for \textdir c.s. is ignored from now on. * \bodydir and \pagedir can now be (re)set even after the first page has been output. * The new callback mlist_to_hlist can be used to intercept the normal conversion of math lists to horizontal lists. * The programs ttf2afm and pdftosrc are removed from the luatex distribution (these belong to pdftex). * fontforge.open() now uses much less memory when opening large (CJK) fonts. * The included libpng is now 1.2.35. * Quite a lot of smaller bugfixes and cleanups (as usual). The archives (just binaries at this time, hopefully there will be a source package later) can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ If you need the sources, please check out via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.31.3 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Packaging modules
by Wolfgang Schuster 21 Feb '09

21 Feb '09

Hi, has anybody of you a nice script to create a zip for a ConTeXt with subfolder for doc, xml and tex files. I have for my letter module now 40+ files and use two different directories, one for changes with all files at one place and another one to create a zip with a tds compliant file structure and a tpm to create the zip with textools. I'm looking now for a script to work with my working dir only and a single file where I list the files which should go in the zip and in which directory they should end (e.g. doc/context/third/...). Something in ruby or better lua, which could be included in context would be nice. Wolfgang

How to ignore specific tree when extracting version from SVN?
by Mojca Miklavec 15 Feb '09

15 Feb '09

Hello, When building the binaries for minimals I decided to use the latest SVN version of XeTeX. On the server I use: cd TRUNK && svn info | grep "Last Changed Rev:" | sed 's/^Last Changed Rev: $.*$$/\1/' && cd .. to determine version of XeTeX and whenever the version changes it triggers rebuilding the binaries. But I just figured out that since Jonathan's last commit about two months ago there have been 71 SVN commits into polyglossia (8) and xepersian (all the rest). This means that any fluent binary builder had to compile XeTeX 71 times (and SVN had to store changes) in the last two months for nothing as texmf tree doesn't influence the binaries. On the contrary, ignoring any changes in texmf tree would mean compiling it just twice or so since August. Any volunteer to send me one-liner to fix that? I'm able to write a ruby script to filter that out, but I'm sure that there must be some extremely simple one-liner (or three-liner) in bash to solve that. Thanks a lot for any hints, Mojca

Re: [dev-context] [NTG-context] new experimental
by Taco Hoekwater 30 Jan '09

30 Jan '09

Hi, An note about the math stuff wrt. luatex itself: there is no released beta yet, but current luatex trunk matches Hans' experimental version. It labels itself version 0.33.0, the revision is #1847, and it seems to be rather stable, despite massive math code changes. There are two big user-visible changes so far (this information is especially for Mojca & Aditya ). * I have added xetex-compatible primitives for the setting of math- and delcodes (and derivates). The names start with \U... instead of \XeTeX..., though. * Many of the math parameters are now separated out; some three dozen math parameters are definable in the eight math styles (\displaystyle, \textstyle, \scriptstyle, \scriptscriptstyle and \cramped versions thereof) using explicit TeX primitives or (easier, automatically) via loading of math fonts. Math fonts can now have a "MathConstants" lua subtable, this is simply the math data generated by fontforge, scaled to size. If this table is present in a font that is assigned to a math family slot, this data will be used instead of the traditional font parameters from \fam2 and \fam3. The manual is updated but not quite up to speed yet, I will fix that over the weekend (mostly explanations missing). Nothing new in OpenType MATH is really supported yet except these MathConstants (and Hans maps the traditional things like verticals extenders and italic corrections to their tfm equivalents), but there is definate progress. Still to do/planned (in planned/proposed implementation order): * Separate out the math spacing rules into parameters * Allow \mathchardef-ed control sequences in text mode * Support for automatic large operator size choosing * Full support for Math-Style extensibles (with overlaps) * Horizontal extensibles (\arrowfill, \bracefill) * Stetch Stacks (for \overbrace cs.) * Stacks (like \atop, but with more than two items) * One-click full font&param switching (for \boldmath) * Prescripts * Flattened accents * Bottom accents * ?? (that list is open for discussion). Have fun, Taco

mptopdf says 'Unable to make mpx file' (using TEX.mp)
by Sanjoy Mahajan 15 Jan '09

15 Jan '09

Here is 'minimal.mp': input TEX beginfig(1) draw thelabel.top(TEX("90"), origin); endfig; end It runs fine through mpost, but running 'mptopdf minimal.mp' instead produces: MPtoPDF 1.3.3 : running 'texexec --mptex minimal.mp' TeXExec | processing graphic 'minimal.mp' This is MetaPost, Version 0.993 (Web2C 7.5.6) (/usr/share/texmf/web2c/natural.tcx) (minimal.mp (/usr/share/texmf-texlive/metapost/base/TEX.mp) (mptextmp.mp >> mptextmp.mp >> mptextmp.mpx ! Unable to make mpx file. l.1 btex 90 etex Transcript written on minimal.log. TeXExec | runtime: 0.040707 MPtoPDF 1.3.3 : no filename matches minimal (After running mpost, the mptopdf command works fine, so delete all files except minimal.mp, then run 'mptopdf minimal.mp' to see the problem.) I'm using the Debian unstable texlive/context packages on i386 (using mkii). Do others see this problem? I don't think it's related to the mpost version or to the Debian packaging. I just tried a moderately recent 'minimals' and mpost 1.110, and the problem is the same. -Sanjoy

Hi all, Since yesterday evening localtime the ntg mail server switched to an external service for spam filtering. It is already clear that the mail server indeed handles much less spam now, so it looks like a great success. Still, it is a rigorous change, and for the new few days I want to ask everybody to keep an eye out for disappearing posts. This message is crossposted. If you want to reply, please do so to me personally, not to the lists. Best wishes, Taco

Luatex beta 0.31.0
by Taco Hoekwater 30 Dec '08

30 Dec '08

Hi all, I have just uploaded the archives for luatex 0.31.0. This is just an intermediate release so that some testing can be done on the updated fontforge embedding. * There are new fields being generated by fontforge.to_table(), and one or two old ones have been removed. These fields are / will be documented in the manual, but very briefly: - MATH table and associated information are now exported (the main reason for the new fontforge code) - Baseline data is now exported (perhaps usable in lua code) - Multiple Master / Glyph variation data is now exported (but useless, for now) - Mac Feature (AAT) information is now exported (perhaps usable in lua code) - If (lookup) names were saved via the PfED table, these will the exported instead of the default, generated names. (as requested by Yannis) * dfont is now treated as an archive format just like ttc when it comes to fontforge.info(). NOTE: that does not mean you can actually use them, because the backend doesn't know yet how to embed dfont fonts in the PDF, that is on the TODO list for the next big beta (0.40.0). * The executables are a lot larger than before. That is because much more of fontforge is included than before. Likely this will stay this way, because this makes upgrading the ff code much easier, and it means that luatex/FF potentially understands more font formats (after upgrading the backend, of course) The archives (just binaries this time) can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ If you need the sources, please check out via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.31.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco _______________________________________________ dev-luatex mailing list dev-luatex(a)ntg.nl http://www.ntg.nl/mailman/listinfo/dev-luatex

The source package should compile normally on all systems that are capable of compiling a modern web2c-based TeX distribution. The win32 package is intended for texlive or a similar web2c-based installation, and has been tested only with TeXLive 2008. These executables will *not* work for miktex, sorry. Of course, we welcome any comments (either good or bad) that you may have. Simply replying to this message is fine, but see the bottom of the message for a more formal way to report bugs and feature requests. ---------------------------------------------------------------------- What is new in MetaPost version 1.102: ---------------------------------------------------------------------- * Printing of 8-bit string characters has been fixed. * In previous versions, TFM files and PFB fonts would not be read properly on big-endian machines (e.g. powerpc) * The MetaPost distribution now contains "A Beginner's Guide to MetaPost for Creating High-Quality Graphics" by Troy Henderson and Stephan Hennig. This tutorial replaces Hobby's mpintro.tex. ---------------------------------------------------------------------- Legal notice / license / bug reports ---------------------------------------------------------------------- MetaPost is a system for producing graphics developed by John Hobby at AT&T, based on Donald Knuth's Metafont.

cont-en.xml / unique keys
by Patrick Gundlach 23 Dec '08

23 Dec '08

Hi, could we add some unique key to the commands? That way we could have a more reliable way to know which command is which. It is useful when you use cd:inherit and refer to a command, such as color (which can be an environment or a standalone command) or commands with variants. It even removes the need for the variant=".." which is not perfect (see setupinterlinespace2 for example, it has variant 2 but there is no setupinterlinespace2 with variant 1). example: <cd:command id="d1e311" name="setuplanguage" file="lang-ini.tex" category="lan guage"> <cd:sequence> <cd:string value="setuplanguage"/> </cd:sequence> <cd:arguments> <cd:keywords n="1"> <cd:resolve name="language"/> </cd:keywords> <cd:assignments n="2" list="yes"> <cd:inherit ref="d1e177" name="installlanguage" n="2"/> </cd:assignments> </cd:arguments> </cd:command> <cd:command id="d1e177" name="installlanguage" file="lang-ini.tex" category="l anguage"> <cd:sequence> <cd:string value="installlanguage"/> </cd:sequence> <cd:arguments> <cd:keywords n="1"> ... ... The attached file generates unique ids for the commands and puts them into the cd:inerit elements (only those that are not set yet) Patrick -- ConTeXt wiki and more: http://contextgarden.net
