Arabic script bug in MKIV
by Mehdi Omidali 17 Oct '08

17 Oct '08

Hi everyone At last I could install minimal context to use the latest luatex (0.30.1) with latest cont-tmf release. Thanks. I don't know if the following is a luatex or Context bug. Sorry if here is not the right place to report this. After compiling the following lines I faced two problems in the output. 1- In the first line words get mixed. 2- In the second line only 456 appeared but it should be 0123456789. The second problem occurs for the specific font that I have used and I can resolve it by using another font. The problem is that in the font, the character ۱ for example is assigned to two unicode characters, one for U+0661 (arabic digit one) and also for U+06F1 (farsi digit one). But MKIV doesn't know this approach. In fact, only digits 4,5, and 6 are different in farsi and arabic so they appeared in the output correctly. XeTeX knows this kind of character assignment. The font can be downloaded from http://irmug.org/portal/index.php?name=Downloads&req=getit&lid=48 Thanks. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \definefontfeature [persian] [mode=node,language=dflt,script=arab, init=yes,medi=yes,fina=yes,isol=yes, liga=yes,dlig=yes,rlig=yes,clig=yes, mark=yes,mkmk=yes,kern=yes,curs=yes] \starttypescript [serif] [persian] \definefontsynonym [Farsi-Light][name:XB Niloofar.ttf][features=persian] \stoptypescript \starttypescript [serif][persian][name] \usetypescript[serif][persian] \definefontsynonym [Serif][Farsi-Light][features=persian] \stoptypescript \starttypescript [Farsi] \definetypeface[Farsi][rm][serif][persian][default] \stoptypescript \def\FarsiGlobalDir {\pagedir TRT\bodydir TRT\pardir TRT\textdir TRT} \definestartstop [farsidocument] [commands={\usetypescript[Farsi]% \setupbodyfont[Farsi,12pt]% \FarsiGlobalDir}] \starttext \startfarsidocument ایضاً این هم همین طور است. ۰۱۲۳۴۵۶۷۸۹ \stopfarsidocument \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

height of balanced columnset?
by Jelle Huisman 17 Oct '08

17 Oct '08

Hi all, Is there a way to get the value of the height of a columnset after it is balanced? I'm looking for some sort of "\columnsetheight" that I can reuse as height=\columnsetheight in a \framed command in a layer. Hope this makes sense, or is the content of a layer supposed to be static? Thanks, Jelle

Hi all, Maybe I miss something, but it looks there is no rule=on command for use in columnsets? I just want a vertical line between the columns in my columnset, how do I get that? Thanks, Jelle

luatex fails
by Hans van der Meer 16 Oct '08

16 Oct '08

I did a complete reinstall for texlive2008 (just out of the box installation) including fresh generation of context and luatex. Of course doing luatools --generate etc. Now luatex doesn't work anymmore. Why? TeXShop log window shows: TeXExec | processing document 'contexttest.tex' TeXExec | no ctx file found TeXExec | tex processing method: context TeXExec | TeX run 1 TeXExec | writing option file contexttest.top TeXExec | using randomseed 84 TeXExec | tex engine: luatex TeXExec | tex format: cont-en LuaTools | using format name: /var/folders/+T/+ThqZosGGzOznrLsOw-fz+++ +TM/-Tmp-/luatex-cache/context/formats/cont-en.fmt LuaTools | no luc/lua with name: /var/folders/+T/+ThqZosGGzOznrLsOw-fz+ +++TM/-Tmp-/luatex-cache/context/formats/cont-en LuaTools | LuaTools | runtime: 0.188 seconds TeXUtil | unable to locate contexttest.tui TeXUtil | shortcuts : 0 TeXUtil | expansions: 0 TeXUtil | reductions: 0 TeXUtil | divisions : 0 TeXUtil | loaded files: 0 TeXUtil | temporary files: 0 TeXUtil | commands: 0 TeXUtil | programs: 0 TeXUtil | tuo file saved TeXExec | runtime: 3.667568 Hans van der Meer

fallbacks for characters
by Thomas A. Schmitz 16 Oct '08

16 Oct '08

Hi all, the answer to this one may be completely obvious, but I haven't found anything: I know we can define fallback fonts in mkiv, but is it possible to define fallbacks for single characters. Let's take 0x0113, "emacron." Is it possible to define "if character is present in current font, use it; else \buildtextaccent\macron e" ? Thomas

metapost behaving different
by Hans van der Meer 16 Oct '08

16 Oct '08

Drawing with a square pen gives better rectangles My metapost code is something like: pickup square pen draw rectangle with label within (macro call) label drawing within the rectangle is essentially done with % prevent wobbling of text boxes with uneven depth pic := textext("\setbox0=\hbox{"&labeltext&"}\dp0=0pt\box0"); % pic goes into rectangle Under mkii this worked but under mkiv the text is mangled. To restore proper text I had to surround this with pen commands: pentemp := savepen; pickup pencircle scaled 0pt; % apparently any size will do % prevent wobbling of text boxes with uneven depth pic := textext("\setbox0=\hbox{"&labeltext&"}\dp0=0pt\box0"); % pic goes into rectangle pickup pentemp; Why is mkii behaving differently and not affected by pen changes? Is this to be expected from metapost (and thus to be considered normal behaviour) or did a bug creep in? Using luatex 0.30.1 and 2008.08.05 18:47 MKIV. [By the way, sometxt doesn't work here and I have to stick with textext.] Hans van der Meer

Running Mark IV / luatex: unknown script: context
by Mildred Ki'Lya 15 Oct '08

15 Oct '08

Hi, Hello everybody, I'm new here. I just subscribed because I'm trying to use LuaTeX / ConTeX Mark IV and i have some problems with it. I'm running TeXlive 2008 installed from ArchLinux and I can't run 'context' from the command line. I'm following the instructions on the page http://wiki.contextgarden.net/Running_Mark_IV It says to first run 'context --make cont-en', and when I do that, I get: MtxRun | error unable to identify cnf file MtxRun | error unable to identify cnf file MtxRun | no cnf files found (TEXMFCNF may not be set/known) MtxRun | unknown script: context After I figured out on the Internet how to set the environment variable TEXMFCNF (I set it to '/usr/share/texmf/web2c/texmf.cnf'), I only get: MtxRun | unknown script: context It seems mtxrun can't find the script mtx-context.lua. I lookad on the Internet, but haven't found any useful information, but I noticed that there was an environment variable I could set to make mtxrun more verbose: MTX_INPUT_TRACE=3 context --make cont-en ~ MtxRun | ! using suffix based filetype: lua MtxRun | ? blobpath asked: context.lua MtxRun | ? filename: context.lua MtxRun | - readable: ./context.lua MtxRun | ! using suffix based filetype: lua MtxRun | ? blobpath asked: mtx-context.lua MtxRun | ? filename: mtx-context.lua MtxRun | - readable: ./mtx-context.lua MtxRun | ! using suffix based filetype: lua MtxRun | ? blobpath asked: mtx-contexts.lua MtxRun | ? filename: mtx-contexts.lua MtxRun | - readable: ./mtx-contexts.lua MtxRun | ! remembered: mtx-context.lua MtxRun | unknown script: context Obviously, the mtx-context.lua file is searched in the current directory, which is my homedir. The file is in fact located at: '/usr/share/texmf-dist/scripts/context/lua/mtx-context.lua' So I cd to that path, and un context again, I get: MTX_INPUT_TRACE=3 context --make cont-en MtxRun | ! using suffix based filetype: lua MtxRun | ? blobpath asked: context.lua MtxRun | ? filename: context.lua MtxRun | - readable: ./context.lua MtxRun | ! using suffix based filetype: lua MtxRun | ? blobpath asked: mtx-context.lua MtxRun | ? filename: mtx-context.lua MtxRun | + readable: ./mtx-context.lua MtxRun | = found by scanning: ./mtx-context.lua LuaTools | ! using suffix based filetype: tex LuaTools | ? filename: cont-en.tex LuaTools | ? filetype: tex LuaTools | ? wanted files: cont-en.tex LuaTools | - readable: cont-en.tex LuaTools | ? blobpath asked: cont-en.tex LuaTools | no tex file with name cont-en.tex LuaTools | LuaTools | runtime: 0.019 seconds MtxRun | running command: luatools --make --compile cont-en MtxRun | total runtime: 0.047 Well, it seems cont-en.tex cannot be found either. It is located at '/usr/share/texmf-dist/tex/context/base/cont-en.tex'. How could I fix my paths? Except for TEXMFCNF, there is No TEX* environment variable defined: env | grep TEX TEXMFCNF=/usr/share/texmf/web2c/texmf.cnf Thanks for any help.
