metapsot vs. graphviz
by Gour 28 Apr '08

28 Apr '08

Hi! While writing some written assignments I have a need to draw some simple diagrams. Tried with Dia, but it's not superb. That's why I'm thinking about learning some graphic programming language... Anyone familiar with metapost & graphviz can write few words how the two compare? Any other suggestion?

question on the luaTeX installation
by Dalyoung Jeong 27 Apr '08

27 Apr '08

Dear all, With a fresh mind, I tried to install luaTeX in my Mac G5(OSX 10.5) as follows: (based on Thomas's instruction) - updating the ConTeXt - making formats - preparing some files like texlua, texluac, luatools, mtxrun. - made a environment variable in .luatex export TEXMFCACHE="/tmp" export TEXMFCNF="/usr/local/texlive/2007/texmf/web2c" export TEXMF="{/Users/dalyoung/.texlive2007/texmf-config,/Users/ dalyoung/.texlive2007/texmf-var,/Users/dalyoung/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/texmf-local/sc ripts/context/lua,/Users/dalyoung/ texmf/scripts}" - run "source .luatex" - run "luatools --generate" it showed a long list without any error message. So far, it looks fine. After the generation, I check the file "cont- new.tex", then it pointed the file in the folder texmf-dist not in the folder texmf-local. I updated the ConTeXt file in the folder texmf-local, but I don't know why it is looking for files under texmf-dist folder not under texmf- local. $ luatools cont-new.tex /usr/local/texlive/2007/texmf-dist/tex/context/base/cont-new.tex I tried to create a format. But "luatools --ini --verbose --compile cont-en" stops with an error message.

some more graphictext
by Peter Rolf 27 Apr '08

27 Apr '08

Hi, graphictext still doesn't work as expected. I get a correct pdf with mkiv; with mkii the '1' is totally missing. Live ConTeXt currently fails in both cases (luatex 0.25.2 there). I have even some more problems with the desired font (Arial, T1), as mkiv creates a broken pdf here (mtxrun is aborted, when calling pstoedit). Looks like a different problem, but one step after the other.

% in URL
by Alan Bowen 27 Apr '08

27 Apr '08

I am trying to typeset a URL that has numerous “%”s in it which I am replacing with “\%”s. The problem is that while the typeset URL works, the printed URL is showing the “\%”s rather than just the “%”s. For example, \useURL [Hoyrup2007bURL] [{http://www.akira.ruc.dk/~jensh/Publications/2005\ %7BR{\percent}7D1_Folkerts_vol-1.PDF}] [] [{http://www.akira.ruc.dk/~jensh/Publications/2005\%7BR\ %7D1_Folkerts_vol-1.PDF}] produces a link that works but reads as http://www.akira.ruc.dk/~jensh/Publications/2005\ %7BR{\percent}7D1_Folkerts_vol-1.PDF I notice that “\&” behaves as it should in this context. Any suggestions or pointers to a solution will be much appreciated. I am using ConTeXt ver: 2008.04.18 14:17 MKII . Best, Alan

urw garamond typescript
by Peter Münster 27 Apr '08

27 Apr '08

Great, now it works! (with luatex-r1188 and context-beta) The typescript from Hans at the end of this message works fine. Some questions for my understanding: - Why 2 \starttypescript-\stoptypescript sections, and not 1? - What does "\setups[font:fallback:serif]" mean? - What is \definetypeface for? - What is the meaning of each parameter of \definetypeface? - Why does the third \starttypescript only have one parameter and no [serif]? After playing around with the typescript, I got the following minmal typescript, that seems to give the same result: \starttypescript [urwgaramond] \definefontsynonym [Serif] [file:GaramondNo8-Reg] \definefontsynonym [SerifBold] [file:GaramondNo8-Med] \definefontsynonym [SerifItalic] [file:GaramondNo8-Ita] \definefontsynonym [SerifBoldItalic] [file:GaramondNo8-MedIta] \definetypeface [\typescriptone] [] [serif] [\typescriptone] \stoptypescript \usetypescript[urwgaramond] \setupbodyfont[urwgaramond] I strongly believe, that Hans' typescript is better, could somebody explain why?

Comments and marks in PDF
by Oleg Kolosov 26 Apr '08

26 Apr '08

Hi All! Adobe Acrobat Reader have special feature, called 'review'. So people can leave marks or comments in PDF file and save them. But AFAIK this can only be done with PDF files generated by Adobe Acrobat Pro. Is there any way to do something similar with files generated by ConTeXt? Basically, I need to pass my work through review process and people often request to add marks directly in files the are looking at. As they are using Adobe's reader exclusively, it would be great to use it's built-in features. -- Best Regards, Oleg Kolosov

Tables, colors, and mkiv
by Aditya Mahajan 25 Apr '08

Hi, Background colors do not work inside tables with mkiv. For example \setupcolors[state=start] \starttext \starttable[|mc|mc|mc|mc|mc|mc|] \HL[2] \BL[6] \AR \NC x_1 \NC x_2 \NC x_3 \NC z_1 \NC z_2 \NC z_3 \NC \AR \HL[2] \NC 0 \NC 0 \NC 0 \NC 1 \NC 1 \NC 0 \NC \AR \NC 0 \NC 0 \NC 1 \NC 1 \NC 1 \NC 1 \NC \AR \stoptable \stoptext Aditya

GNU Emacs - Context Command Reference
by Suno Ano 24 Apr '08

24 Apr '08

I was looking for a command reference that includes all Context commands. There are a few choices to pick from [0] (see "Find Definition"). However, since I am a big GNU Info fanboy -- I love to not leave Emacs while writing Context source etc. -- I was looking for something "faster" than fiddling around with some PDF manual respectively the on-line command reference. I am now using [1] which works quite nice [2] ... ,----[ Debian repository for etexshow? ] | Since I am on DebianGNU/Linux, I was wondering if maybe someone knows a | repository that provides a .deb for etexshow?

This does the job. All I need now is a version (\Monthshort ??) which puts the first letter in uppercase, Jan , Feb, etc. Thanks, Richard ________________ www.converteam.com Converteam UK Ltd.
