The cases where fontforge is refusing, are cases which are best handeld inside metafont, where one has the knowledge: a.) elliptical curves, which are represented by polygons (lots of points and resolution depandend) and should converted to something smoother, and b.) short epicycles, which are also artifacts from penmotions, which can easyly be detected and replaced by an corner point.

Possible bug in core-tab?
by Aditya Mahajan 17 Aug '07

17 Aug '07

Hi Hans, || does not work with tables, and until now I thought that this was a limitation of tables. But upon reading core-tab, it appears that you make a lot of effort to make sure that || works correctly, but it does not. I think that this is due to a mistake in the definition of pushouterbarandquote. Currently it is defined as \gdef\pushouterbarandquote {\ifForgetTableBarAndQuote \let|\letterbar \let"\letterdoublequote \ifnum\catcode`\|=\@@active \let\outertablebar |\else\let\outertablebar \relax\fi \ifnum\catcode`\"=\@@active \let\outertablequote"\else\let\outertablequote\relax\fi \fi} Shouldn't it be the other way round? That is first save the current meaning of | and ", and then redefine it. So, \bgroup \catcode`\|=\@@active \catcode`\"=\@@active \gdef\pushouterbarandquote {\ifForgetTableBarAndQuote \ifnum\catcode`\|=\@@active \let\outertablebar |\else\let\outertablebar \relax\fi \ifnum\catcode`\"=\@@active \let\outertablequote"\else\let\outertablequote\relax\fi \let|\letterbar \let"\letterdoublequote \fi} \egroup This makes sure that || works correctly. The redefinition of " and | was added last November. http://foundry.supelec.fr/plugins/scmsvn/viewcvs.php/tex/context/base/core-… Aditya

t-bib - publicationlist space between [111] and items // luatex // error for \currentdate [y, -, mm, -, dd]
by Tobias Burnus 17 Aug '07

17 Aug '07

Hello, I use \setuppublications[numbering=yes,refcommand=num] and have more than 99 references. Thus in the reference list the "]" of "[111]" overlaps with the entry behind. I tried \setuppublicationlist with samplesize= and with distance=/width=, but this did not help. Any idea how to solve this (best would be of cause automatically). * * * I'm now trying to get LuaTeX running with a TeXLive2007 system and the current cont-tmf.zip. I did: - Compiled luatex and installed luatex - Created symbolic link from texluac to luatex - Set TEXMFCNF=<dir> to the directory which contains texmf.cnf Questions and problems: a) Where do I find mtxrun ? I found ./scripts/context/lua/mtxrun.lua, but lua ./scripts/context/lua/mtxrun.lua gives the error message: lua: ./scripts/context/lua/mtxrun.lua:3949: attempt to index global 'lua' (a nil value) The line is: if lua.bytecode then -- from 0 upwards b) If I run: texmfstart texexec --make --lua the metafun.mem is nicely generated but cont-* is not: LuaTools | version 1.1.1 - 2006+ - PRAGMA ADE / CONTEXT LuaTools | loading /home/tob/texmf/texmf.cnf LuaTools | preparing configuration in /home/tob/luatex-cache/ [...] LuaTools | runtime: 0.29 seconds TeXExec | using tex engine luatex TeXExec | using tex format path /home/tob/texmf/web2c/luatex TeXExec | generating tex format cont-en Error in lua file loading: ?:0: attempt to index global 'instance' (a nil value) [...] LuaTools | running command: luatex --ini --lua="cont-en.luc" "/home/tob/texmf/tex/context/base/cont-en.tex" \dump LuaTools | LuaTools | runtime: 0.3 seconds TeXExec | generating tex format cont-nl Error in lua file loading: ?:0: attempt to index global 'instance' (a nil value) Which seems to be the same error as in (a). * * * Since the update of cont-tmf.zip, I get an error (pdfetex) for: \currentdate [y,-,mm,-,dd] \bye ! Missing number, treated as zero. <to be read again> { \convertnumber ... \s!default \fi \fi \endcsname { \number #2} Any idea what goes wrong here? Tobias

inline diagrams/charts?
by Henning Hraban Ramm 17 Aug '07

17 Aug '07

Hi there! A long time ago there was a discussion about some kind of tiny block charts that run within the text. Now I would need such for the summary of a poll. But I can't remember the name, and thus I can't find the thread and website. Can you help me? Greetlings from Lake Constance!

disabling reuse of figures
by Saji Njarackalazhikam Hameed 16 Aug '07

16 Aug '07

Dear All, It is a rather strange problem, I am compiling a presentation file using ConText. I use the \startcombination enviroment to make a panel containing 4 plots. In the source file, I prescibe a different figure file (*.png) for each page. ConText is however reusing the first set of figures so that the panel in each page looks the same as in the first page. Is there a way to disable the "reusing of figures"? A minimal example is reproduced below. thanks for any suggestions. saji \input setups \starttext \startcombination[2*2] {\externalfigure[/apcc01/OPER/AFS/FIG/3-MON/MME_OUT/FORECAST/GAUS/2007/6/Monthly/JUN/Global/prec.png]} {\externalfigure[/apcc01/OPER/AFS/FIG/3-MON/MME_OUT/FORECAST/GAUS/2007/6/Monthly/JUN/Global/t850.png]} {\externalfigure[/apcc01/OPER/AFS/FIG/3-MON/MME_OUT/FORECAST/GAUS/2007/6/Monthly/JUN/Global/z500.png]} {\externalfigure[]} \stopcombination \page \startcombination[2*2] {\externalfigure[/apcc01/OPER/AFS/FIG/3-MON/MME_OUT/FORECAST/SCM/2007/6/Monthly/JUN/Global/prec.png]} {\externalfigure[/apcc01/OPER/AFS/FIG/3-MON/MME_OUT/FORECAST/SCM/2007/6/Monthly/JUN/Global/t850.png]} {\externalfigure[/apcc01/OPER/AFS/FIG/3-MON/MME_OUT/FORECAST/SCM/2007/6/Monthly/JUN/Global/z500.png]} {\externalfigure[]} \stopcombination \stoptext

There was once (1990) an article in TUGboat 11:4, pages 525-541 which discribes an patch to mf84. The patched mf could produce type3 fonts. Should'nt it be possible to do the same for type1?

Scite
by Wolfgang Werners-Lucchini 16 Aug '07

16 Aug '07

Hallo! I had a little problems to install scite 1.74 for conTeXt under Windows. First, I tried to import both 'context.properties' and 'default.properties' in this order in 'SciteGlobal', but only the second(?) was imported. I tried to comment a few other imports, which I don't use, but Scite refuses to import context. Finally I imported 'context.properties' in 'default.properties'. That works! The CTX-tools redefine the keys Ctrl-B and Ctrl-E which normaly are used to insert abbreviations (which can be language-dependend now) and to find matching braces. I replaced the 'Open Logfile' with Ctrl- L (former Ctrl-E) and deleted the 'Check Text' entry completly, because I am calling ISpell with Ctrl-I therefore. It remains one problem: In the Scite console, the backspace key is not really working (the char is deleted only on screen, not in the buffer). Has anybody a solution? Wolfgang
