Unicode in \pdfinfo
by Khaled Hosny 03 Jul '08

03 Jul '08

\pdfinfo doesn't seem to support Unicode, when I compile the attached example with luatex I get symbols like Ù‡ØµØ© instead of the proper (Arabic) Unicode strings. Shouldn't luatex default to Unicode here too? Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

The current archive is only available to the list members
by Jonathan Fine 02 Jul '08

02 Jul '08

Hello I've been lurking on this list for a couple of months, and it seems to me that it would be really helpful to the TeX and Lua communities if their members could read the messages, without having to subscribe to the list. For what it's worth, I think most open-source devel mailing lists are publicly viewable. I'd like to know what the other list members think. Jonathan

Beta 0.28.0 and \pattern
by Jonathan Sauer 02 Jul '08

02 Jul '08

Hello, Take the following PlainTeX example: --------------------------------------------------------- % \input hyphen % A \showhyphens{regarding} \bye --------------------------------------------------------- This results in: --------------------------------------------------------- This is LuaTeX, Version snapshot-0.28.0-2008070118 (Web2C 7.5.6) (hyphenOther.tex Underfull \hbox (badness 10000) in paragraph at lines 5--5 [][] \tenrm regarding ) (see the transcript file for additional information) No pages of output. Transcript written on hyphenOther.log. --------------------------------------------------------- When uncommenting line (A), the result is as follows: --------------------------------------------------------- This is LuaTeX, Version snapshot-0.28.0-2008070118 (Web2C 7.5.6) (hyphenOther.tex (/usr/local/teTeX/share/texmf.tetex/tex/generic/hyphen/hyphen.tex) Underfull \hbox (badness 10000) in paragraph at lines 5--5 [][] \tenrm re-gard-ing ) (see the transcript file for additional information) No pages of output. Transcript written on hyphenOther.log. --------------------------------------------------------- Compare with beta 0.27: --------------------------------------------------------- This is LuaTeX, Version snapshot-0.27.0-2008062418 (Web2C 7.5.6) (hyphenOther.tex Underfull \hbox (badness 10000) in paragraph at lines 5--5 [][] \tenrm re-gard-ing ) (see the transcript file for additional information) No pages of output. Transcript written on hyphenOther.log. --------------------------------------------------------- So it seems that hyphenation patterns are not dumped into the format file anymore. Incidentally, contrary to what the manual says in section 9.5, the format file is not compressed (or at least not all of it): When opening it with a text editor, the hyphenation patterns, when using beta 0.27, are contained as plain text. A quick test using Zip on the PlainTeX format file reduces its size from 356K to 288K. Another test with a format file of 34M (containing the 420,000-word list from the dehyph-exptl project as hyphenation exceptions) shows a reduction to ~26M. Jonathan

Luatex beta 0.28.0 released
by Taco Hoekwater 30 Jun '08

30 Jun '08

Hi all, I have just uploaded the archives for luatex 0.28.0, another intermediate release leading up to TUG 2008. This release matches SVN revision #1357. There is one new feature: There is now experimental support for non-trivial discretionaries following explicit hyphens. In analogy to \prehyphenchar and \posthyphenchar, there are two new parameters \preexhyphenchar en \postexhyphenchar. Both new parameters default to zero (nothing). When set to a nonzero value, the parameter is added to either the pre- or post- break text. Note that this is *in addition to* the hyphen already in the input. Testing and comments are very welcome. Here is a short example (no idea what is says): \pdfoutput=1 \hsize=2in \postexhyphenchar=`- Seria bom se eu pudesse t\^e-lo mantido como amigo, mas por mais bem-intencionado que eu fosse, n\~ao foi possivel \bye Bugs fixed compared to 0.27.0: * Words that started off with a character with a zero \lccode were never hyphenated at all. * There was a bug in the new active characters code that prevented the latex format from being built (with Invalid character error). * There is a temporary fix for the sometimes appearing "Font has a bad FontBB" message from Acrobat. * \leaders did not actually stretch enough (the last bit of glue that has to line up the line endings was never output to the PDF). * Bad paragraph-related callbacks could result in luatex crashing. * The pre_linebreak and post_linebreak filters were never called when \output was active (this was a leftover of a superceded optimization). * 'skipping' language codes when setting up \patterns c.s. did not work (it used the next empty slot instead of the actual value of \language). * Using multiple 'attr' keywords on box items could cause random crashes. * Calling lang.hyphenate() with one argument (without specifying a tail node) could crash. * The luatex pdf banner and version reporting is cleaned up a bit. * Conflicting patterns inside \patterns now give an error: ! Conflicting pattern ignored. (duplicate identical patterns are ignored without error). The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Re: [Dev-luatex] [XeTeX] A native support for SVG

Inkscape can embed Type1 fonts in its PDF output, some thing like "inkscape --export-pdf=file.pdf --export-embed-fonts file.svg", but I didn't try it. Another way is to convert text to paths "--export-text-to-path". Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

Hyphenation of "(regarding"
by Jonathan Sauer 25 Jun '08

25 Jun '08

Hello, take the following PlainTeX file: %&luatex \lccode`\(=0 % Just to be on the safe side \showhyphens{regarding} \showhyphens{(regarding} \showhyphens{regarding)} \bye This results in: This is LuaTeX, Version snapshot-0.25.3-2008060319 (Web2C 7.5.6) (hyphenOther.tex Underfull \hbox (badness 10000) in paragraph at lines 5--5 [][] \tenrm re-gard-ing Underfull \hbox (badness 10000) in paragraph at lines 6--6 [][] \tenrm (regarding Underfull \hbox (badness 10000) in paragraph at lines 7--7 [][] \tenrm re-gard-ing) ) (see the transcript file for additional information) No pages of output. Transcript written on hyphenOther.log. Time elapsed: 1 seconds. It seems that the "(" -- but not the ")" -- is treated as part of the word, even though its \lccode is zero. What am I doing wrong? Thanks in advance, Jonathan
