Luatex 0.50.0 announcement
by Taco Hoekwater 25 Dec '09

25 Dec '09

Hi, I have just uploaded the archives for a new luatex release, 0.50.0. This release starts a new chain of stable beta's. New features: * Fonts now listen also to the 'extend' key in the lua font metrics table, and the processing for this is done via de pdf text matrix instead of via the font matrix, which means it now works for all font types. * The embedded Metapost library is now at version 1.209. Dropped features: * It is no longer possible for fonts from embedded pdf files to be replaced by / merged with the document fonts of the enveloping pdf. This regression may be temporary, depending on how the rewritten font backend will look after beta 0.60. Bug fixes: * Use of \middle confused the \mathstyle operation. * \pdfcolorstack handling was broken. * node.unset_attribute() had a bug whereby it inverted the requested result in some cases (the node on which the unset was called was sometimes the only node at the current level that *kept* the attribute). * During font expansion, the internal font copy had one character information object less than the original, resulting in the disappearance of a glyph in some fonts when font expansion was active. * Placement of operator scripts of OT MATH fonts is adjusted to be conformant with Word's logic where the italic correction is only used to tuck in the subscript and for nothing else. * luafontloader.open() no longer writes directly to stderr in case of internal font errors. * Any <pdf_refobj_node>.objnum could not be assigned to. * The lua 'pdf' table could not be assigned to. * The lua 'md5' library was returning incorrect results on 64-bit architectures. * Luatex now compiles on GNU Hurd systems. * Fix segfault when embedding stream file object (these backend segfaults were a side-effect of the string pool patches). The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.50.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Math sizes & styles
by Javier Múgica 24 Dec '09

24 Dec '09

Can a math layout like the one of the attached image be obtained with TeX? I think it is impossible. The size of the fractions is slightly smaller than that of the main text, and the script sizes for both of them are the same. When is it planned to make configurable the hardwired set of math styles as well as the tree of math style changes, if planned at all? In this example the changes from the main style to fractions and scripts would need to be decoupled. Happy Christmas Javier A. Múgica

Re: [Dev-luatex] Bug#562176: luatex: FTBFS on hurd-i386: unconditional PATH_MAX usage

Hi Taco, Pino (in cc) found that luatex does not build on GNU/Hurd, but some simple changes does fix that. You might add that to luatex itself.

order of node linking matters
by Paweł Jackowski 23 Dec '09

23 Dec '09

Dear Colleagues, the following code fails assertion (luafont.c, line 1950). But it is enough to transpone last two lines of lua code to avoid it. Could someone explain why the order of node linking matters here? \nokerns=1 \noligs=1 \setbox100=\hbox{ab\-xx} \directlua{% here we move glyph b into disc node local a = tex.box[100].list % glyph a local b = a.next % glyph b local d = b.next % discretionary local _ = d.pre % prebreak dash a.next = d d.prev = a % couple glyph a with disc d.pre = b % let glyph b be prebreak b.next = _ _.prev = b % couple glyph b with dash } \hsize0pt \overfullrule0pt \hfuzz\maxdimen % force hyphenation \unhbox100 % flush the list \end Apparently the assigment discretionary.pre = someglyph someglyph.next = someother and someglyph.next = someother discretionary.pre = someglyph is not the same. Why? Warm greets to u all, Paweł -- Pawe/l Jackowski P.Jackowski(a)gust.org.pl
