Hi, I uploaded new zips.

bug in mplib?
by Thomas A. Schmitz 15 Apr '08

15 Apr '08

Hi all, I just noticed that with the new incarnation of metapost, arrows behave somewhat erratically. Take this minmal example: \starttext \startuseMPgraphic{arrowtest} z1=(0,0) ; z2=(3cm,0) ; ahlength := 15pt ; pickup pencircle scaled 5pt ; drawarrow z1--z2 ; \stopuseMPgraphic \useMPgraphic{arrowtest} \stoptext compile it with mkii and mkiv and observe the difference. All best Thomas

Unable to generate luatex formats
by Michael Green 15 Apr '08

15 Apr '08

[A] My experience is similar to Hans van der Meer's (quoted below). luatools --generate does what I think it's supposed to. luatools luat-env.lua returns a blank line. [B] I followed Thomas Schmitz's instructions and used the source .luatex method, for what it's worth. http://archive.contextgarden.net/message/ 20071002.175335.21873a03.en.html .luatex contains: export TEXMFCACHE="/tmp" export TEXMFCNF="/usr/local/texlive/2007/texmf/web2c" export TEXMF="{/Users/michaelgreen/.texlive2007/texmf-config,/Users/ michaelgreen/.texlive2007/texmf-var,/Users/michaelgreen/Library/ texmf,/usr/local/texlive/2007/texmf-config,!!/usr/local/texlive/2007/ texmf-var,/usr/local/texlive/2007/texmf,/usr/local/texlive/2007/../ texmf-local,!!/usr/local/texlive/2007/texmf-dist}" export LUAINPUTS="{/usr/local/texlive/texmf-local/tex/context/base,/ usr/local/texlive/2007/texmf-dist/scripts/context/lua,/usr/local/ texlive/texmf-local/scripts/context/lua}" [C] Is there a chance that this is a permissions issue? I had to make luatools.lua executable by hand. None of the other files in that directory are executable, where 'that' directory is: /usr/local/texlive/texmf-local/scripts/context/lua mjg > From: Hans van der Meer <hansm(a)science.uva.nl> > Subject: Re: [NTG-context] Unable to generate luatex formats > > Same thing here.

Module documentation
by richard.stephens＠converteam.com 15 Apr '08

15 Apr '08

Hello all, I have been using Context for a while now and have learnt a lot from the manuals and wiki. I now want to start to use features that are not documented. On the wiki (http://wiki.contextgarden.net/Official_ConTeXt_Documentation#ConTeXt_Sources) I found the following command for producing a pdf output for a module: texmfstart texexec --module kpse:core-tab.tex which seems ideal for learning more. When I run the above command line it creates a .ted file but then complains: "I can't find the format file 'cont-en.fmt'!" On Luigi Scarso's page (http://wiki.contextgarden.net/User:Luigi.scarso/modules.pdf) he suggests the following: texexec --module --pdf core-tab.tex but this returns no output at all, and no pdf. I am working on Windows. I installed (this week) from the context/install/mswincontext.zip on the Pragma site and normally build from the Scite editor. Can anyone suggest what I'm doing wrong? Thanks. Richard Stephens

Is there a find_file function necessary to find the mem-file given in 'mem_name' or is such a function only necessary for file-names in 'mp:execute'?

fonts and luatex
by Antoine Junod 15 Apr '08

15 Apr '08

Hello, List! Is it still needed to 'install' fonts with luatex and otf fonts or is it enough to drop the otf font files in a random place inside texmf/fonts/opentype/ ? Thanks for your reply, -AJ

Wolfgang and Mojca, Thank-you for your replies. They have enabled me to set up a little batch file to make life easier when I want to generate a module document. Thanks, Richard Stephens

The two files Taco pointed to *appear* to be OK (though I'm too inexperienced to say with certainty). That leaves something esoteric or a tossed salad of old and new code. Since this is mainly a matter of learning and curiosity for me, I'll wait and see how things develop for a bit.

\hyphenatedfile redefined!!
by Aditya Mahajan 14 Apr '08

14 Apr '08

Hi, Typeset this file :) \starttext The file \filename{knuth} contains a quotation from Don Knuth, the creator of \TEX. \stoptext core-ver.tex defines \filename to be \unexpanded\def\filename#1{{\tttf\hyphenatedfile{#1}}} and supp-lan.tex defines \hypenatedfile to be \let\hyphenatedfile\hyphenatedurl However this is redefined in supp-box.tex, due to which \filename gets redefined. %D \macros %D {hyphenatedword, %D hyphenatedpar, %D hyphenatedfile, %D dohyphenateword} %D %D The next one is a tricky one. \PLAIN\ \TEX\ provides %D \type{\showhyphens} for showing macros on the terminal. When %D preparing a long list of words we decided to show the %D hyphens, but had to find out that the \PLAIN\ alternative %D can hardly be used and|/|or adapted to typesetting. The next %D two macros do the job and a little more. Although, I cannot gather this from the definition, it seems that \hypenatedfile is showing all the hyphens in a file. One of the macros need to get a different name :) Aditya
