It really doesn't hurt if we define two languages nb and nn (such as there are multiple languages for Czech/Slovak, Croatian/Bosnian/Serbian), and "remove" no, in the sense that no can be left as a synonym to nb only. Specifically: ------------- Hans F. Nordhaug: > I think "no" should be deprecated and giving a (useful) warning/error - > telling people to switch to "nb". ------------- Karl: To sum up, we need the following language codes: nb and nn. And we need the following mappings: bokmal --> nb bokmål --> nb (if possible) nynorsk --> nn norsk --> nb (with warning) norwegian --> nb (with warning) ------------- Mojca: You also need to ask Hans how to provide a "'no' is not allowed language switch" warning or error. What are you planning to do with the "norwegian" interface? Hans: why is "Norwegian" currently not listed in mult-sys.tex? Because only languages which need something different than "ec" need to be listed there or is there some other reason? Hans, you pointed out the chineese module ... but from what I can see there, one needs to include the module explicitely and ConTeXt users are pampered too much ;) (i.e. everything should happen automatically) - is there a way to say something like this? \startlanguage[nn] \setupitemize[stopper=] \definesymbol[1][\endash] \stoplanguage ------------- Karl/Mojca/Karl: >> leftquotation=\leftguillemot, >> rightquotation=\rightguillemot, > >Are the old values wrong or just an alternative? Well, there are no very strict rules in Norwegian; you *can* use every possible quotation mark. But the guillemots are certainly the preferred ones for (outer) quotations. ------------- Karl: My suggestion is \definesymbol[1][{\symbol[dash]}] \definesymbol[2][{\symbol[star]}] \definesymbol[3][{\symbol[circle]}] \definesymbol[4][{\symbol[bullet]}] \definesymbol[5][{\symbol[triangle]}] and leave levels 6+ at their defaults. Norwegian people, feel free to comment on this. :) ------------- Mojca: so it would really make sense to enable something like \startlanguagespecifics[nb] \setupitemize[stopper=] \definesymbol[1][{\symbol[dash]}] \definesymbol[2][{\symbol[star]}] \definesymbol[3][{\symbol[circle]}] \definesymbol[4][{\symbol[bullet]}] \definesymbol[5][{\symbol[triangle]}] \stoplanguagespecifics Perhaps that exists already, but I don't know how to do it. For Slovenian and Hungarian, the same "problem" exists. Now I use \def\placedotafter#1{#1.} \setuphead[section][numbercommand=\placedotafter] although it would be more clean if one could have something similar to \startlanguagespecifics[sl] \setupheads[stopper=.] \stoplanguagespecifics in default settings once that will be implemented. ------------- Karl: \setupheadtext [\s!nb] [\v!content=Innhold] \setupheadtext [\s!nn]

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

Luatex beta 0.27.0 released
by Taco Hoekwater 24 Jun '08

24 Jun '08

Hi all, I have just uploaded the archives for luatex 0.27.0. This is an intermediate release leading up to 0.30.0, to be released around TUG2008. There are just too many changes to wait another month :-) Bugs fixed compared to 0.25.3: * Unicode reencoding support for non-standard (i.e. older) Type1 fonts is now somewhat less broken than it was (#25) * .vf fonts using specials crashed luatex * luatex would crash on --\par (#33) * An attempt is made to get a sane default value for StemV in the created pdf (#32) * We can now guarantee that %PDF-1.* header is printed before the first pdf.print() output * lang.hyphenate() was broken * insert_before(a,a,b) was broken (#37) * argv[0] is now cleaned up before being used as a default for mem_name and prog_name (#28). * luatex would crash on loading extended fonts (fonts loaded via lua callbacks) from a format file. * The fix for pdftex bug #799 is backported from pdftex 1.40.4. * slnunicode had a bug in the unicode.utf8.gmatch iterator. * Queries of nonexisting fontdimens could cause a crash. * luatex would crash on {\textdir TLT\pardir TLT x\break\par } * Fixed wrong placement of lines in mixed-direction paragraphs that could happen in some situations. Other news: * Luatex now includes luasocket (#35) See http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/ for usage. There is a new commandline option: --nosocket to disable this, and that is also implied by --safer. NOTE to the binary builders: there are some unfixed configure problems when you need to add a specific library to get socket support on your platform. You probably will have to edit the generated Makefile by hand (search for 'socketlib'). * There is ongoing development to the 'img' and 'mplib' libraries. See the reference manual for details. * The 'character commands' in virtual fonts now support image inclusion. See the reference manual for details. * Lua error messages now include the call stack. * \directlua and \latelua have been extended to accept a 'name' keyword. The argument is a token list that is used as the lua name of this chunk in lua error messages and call stack prints. (#42) * The lua chunk names can be interfaced via a new virtual table called lua.instancename, the values in that function as defaults in the absence of 'name' keywords. * The 2-plane limit on active character range is removed (#12). * Subsetted TTF fonts in the PDF now retain the cmap table. * There is a new Lua variable os.selfdir. This contains the full absolute pathname of the directory that the executable resides in (with symlinks resolved) * There is a new function os.uname() this returns a lua table containing various platform information items. * The node library now uses text strings for direction specifiers instead of numbers. See the reference manual for details. * The 'E' (edit) as error response functionality is now a noop. * Adding luatex 0.25.3 to texlive resulted in a few minor backports, in particular: Support for mktexfmt is added, and luatangle now identifies itself as such (instead of calling itself otangle). * We fixed a whole series of portability problems (but we probably introduced new problems as well). * Most (all?) files now have a corrected Copyright header, and link in $Id$ and $URL$ into the object file. * Some unnecessary files were removed from the distribution. 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

format() without formatting
by Peter Rolf 17 Jun '08

17 Jun '08

Hi, can one of the experienced lua programmers here think about a special version of format()? This function in general is of great help (short, good readable code), but in combination with direct written pdf code (like in mlib-pdf.lua) is has a major drawback. All numbers are written with fixed size (as normally intended in formatted output). As a result you get '0.000000' instead of a short '0'. Look in an uncompressed pdf and you will see how much space is wasted there in total. Here an example (pdf code segment of a mp graphic). % mps graphic 1: begin q q /Pattern cs 10.000000 M 1 j 0.000000 0.000000 m 94.486725 0.000000 188.977783 0.000000 283.464508 0.000000 c 283.464508 28.346451 l 188.977783 28.346451 94.486725 28.346451 0.000000 28.346451 c 0.000000 0.000000 l W n /MpSh1 sh Q 0 g 0 G 1 J 0.100006 w 0.000000 28.346451 m 283.464508 28.346451 l S 0 g 0 G 0 g 0 G 0.100006 w 283.096863 28.194168 m 283.464508 28.346451 l 283.096863 28.498734 l 283.096863 28.194168 l h B 0 g 0 G Q % mps graphic 1: end With enabled compression things don't look that bad (regarding to file size), but it's still a unnecessary waste. To summarize it: the new function should act like 'format', but it should use the minimal number of digits. Also there should be the possibility to adjust the number of digits after the point (current accuracy for floats: 1/1000000 pt). Any thoughts? Regards, Peter

TEXMFHOME and the file database
by Oliver Buerschaper 07 Jun '08

07 Jun '08

Hi, I tried to set up a TEXMFHOME directory for on-the-fly additions to the TeX tree. I'm working with the 2008.05.27 beta of MKIV, i.e. there are no setuptex scripts, environment variables and the like, just texmf.cnf and texmfcnf.lua in texmf/web2c. I've modified the former according to: --- [...] %HOMETEXMF = /nonexist TEXMFHOME = $HOME/Library/texmf TEXMF = {$TEXMFHOME,!!$TEXMFPROJECT,!!$TEXMFFONTS,!! $TEXMFLOCAL,!!$TEXMFCONTEXT,!!$TEXMFEXTRA,!!$TEXMFMAIN} [...] --- Now LuaTeX only recognizes files put into $TEXMFHOME after the file database has been regenerated via bash# luatools --generate --verbose However, I would like LuaTeX to find these files without the need for rehashing just as if they were in the current working directory. What am I missing? Best wishes, Oliver
