Help with fonts needed
by Taco Hoekwater 10 Apr '09

10 Apr '09

Hi all, The next big release of luatex will be about (opentype) math. One of the prerequisites of that is the ability to handle the opentype math features, and that means updating the embedded fontforge code. This is what I am currentlu working on. While updating the fontforge.to_table() code, I noticed that there where still some todo items in the source and it would be nice if these could be resolved as well. If have written tentative code for those now, but I do not have the fonts to go with the code so it is not at all unlikely that there are crash-level bugs and/or misconceptions. In order to make luatex even better, I need your help finding good examples of each of the following font types: * Apple dfont collections * AAT fonts in all forms * Apple Multiple Master (AAT "fvar") * Adobe's Type1-based Multiple Master * Fonts specifying baseline settings (OT "BASE" | AAT "bsln" ) * Fonts specifying justification data (OT "JST" | AAT "just") Please drop me a line if you can help out with any of these... Best wishes, Taco

luatex beta 0.38.0
by Taco Hoekwater 10 Apr '09

10 Apr '09

Hi, I have just uploaded luatex 0.38.0. This is a beta in the process towards 0.40.0, the version that will be included in texlive 2009. This beta will be shortlived, the plan is to release the next (hopefully last) intermediate beta within a week. What's new: * tex.enableprimitives() had a bug were previously defined (but currently undefined) control sequences prevented the creation of the new csname. * The special calling format callback.register('name', false) not only disables the callback, but also the builtin code it is supposed to replace. * Empty \localleftbox and \localrightbox -es are now suppressed. * Support for <f>.MathConstants.SubscriptShiftDownWithSuperscript was added, to solve the lack of "sub2" in OpenType math. * Luatex now supports horizontal super- and subscript placement corrections via the OpenType MATH mathkern table. See the manual for details. * node.write() no longer copies its argument node list before appending it. * There are six new primitives that are verbose forms of one and two byte special tokens: \Usuperscript \Usubscript \Ustartmath \Ustopmath \Ustartdisplaymath \Ustopdisplaymath * The attribute node leaks in math mode and alignmetns have been fixed. * The 11 simple math noads are now combined into a single "noad" node type. * Static linking against libstdc++ is working once again. * There is a small fix in the keyword scanner to solve the problem of 'Runaway ... while scanning ???' that could happen for some primitives. * Lua now also has the "architecture independent bytecode" patch applied. * Lua is updated to version 5.1.4 with coco patches 1.1.5, and lpeg is now 0.9. * Some TRT/TLT backend bugs are fixed. * Various manual updates. The archives (now including source again) can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.38.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

\primitive\pdfoutput cannot be queried
by Heiko Oberdiek 10 Apr '09

10 Apr '09

Hello, AFAIK, an expression with \primitive will become expandable if and only if the primitive is expandable. (pdfTeX: \pdfprimitive) The problem arises with \pdfoutput, a kind of count register. Therefore it isn't expandable. This doesn't hurt, if \pdfoutput is set. However it cannot get its value anymore: \gdef\pdfoutput{\primitive\pdfoutput} a) \ifcase\pdfoutput fails with ! Missing number, treated as zero. <to be read again> \primitive b) \ifcase\the\pdfoutput fails with ! You can't use `\primitive' after \the. c) \ifcase\number\pdfoutput fails with ! Missing number, treated as zero. <to be read again> \primitive d) \count0=\pdfoutput fails with ! Missing number, treated as zero. <to be read again> \primitive Yours sincerely Heiko <oberdiek(a)uni-freiburg.de>

tex.enableprimitives also fails for undefined primitives
by Heiko Oberdiek 10 Apr '09

10 Apr '09

Hello, test file: \def\msg#{\immediate\write16} \msg{\meaning\Xpdfoutput} \begingroup \csname Xpdfoutput\endcsname \endgroup \msg{\meaning\Xpdfoutput} \directlua{tex.enableprimitives('X', {'pdfoutput'})} \msg{\meaning\Xpdfoutput} \csname @@end\endcsname\end Result: 3 x "undefined" After reading the documentation I expected: 2 x "undefined", 1 x "\pdfoutput" | Then it will check for the existence of the constructed csname. If the | csname is currently undefined (note: that is not the same as \relax), it | will globally define the csname to have the meaning: run code belonging to | the primitive `name'. If for some reason the csname is already defined, it | does nothing and tries the next pair. Either there is a bug in the implementation or in the description ("is already defined" --> "is or was already defined"). Workaround: \directlua{tex.enableprimitives('Workaround', {'pdfoutput'})} \global\let\Xpdfoutput\Workaroundpdfoutput Yours sincerely Heiko <oberdiek(a)uni-freiburg.de>
