BTW: pdfinfo a.pdf Title: a Creator: ConTeXt - 2011.03.11 11:45 Producer: LuaTeX-0.65.0 Page size: 595.276 x 841.89 pts (A4) File size: 5253 bytes PDF version: 1.6 pdffonts a.pdf name type emb sub uni object ID ------------------------------------ ----------------- --- --- --- --------- ZWRPON+TeXGyrePagella-Regular CID Type 0C yes yes yes 18 0 That file was generated with MKIVtexgyrepagella-regular.otf using mkiv? Now if I print that via CUPS-PDF. pdfinfo cups-a.pdf Producer: Apple pstopdf Page size: 595 x 842 pts (A4) File size: 2891 bytes PDF version: 1.3 pdffonts cups-a.pdf name type emb sub uni object ID ------------------------------------ ----------------- --- --- --- --------- CFOFGB+TeXGyrePagella-Regular Type 1C yes yes no 4 0 du -b a.pdf cups-a.pdf 5253 a.pdf 2891 cups-a.pdf So CUPS does some font conversion here. I would assume that will also happen when printing to a regular network printer. Maybe this step breaks on your system. And that is why sending the file to the printer directly causes no trouble. Florian PS: Is there a way to force luatex writing fonts in CFF instead CID format?

\doif... and Lua
by Procházka Lukáš Ing. - Pontex s. r. o. 25 Mar '11

25 Mar '11

Hello, is it possible to use a block of context code depending on a value of a Lua variable? I tried something like: --- \starttext \directlua{test = true} %\directlua{test = 5} %\directlua{test = "a"} \doifempty{\directlua{return test}} %\doifempty{\directlua{test}} {Yes} {No} \stoptext --- But this gives me always "No". - I'm not sure if this is a good way, and whether attempt to use \doif(...) macro is a good idea at all. Any (better) solution? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.

structure: products and subfolders
by Paul Menzel 25 Mar '11

25 Mar '11

Dear ConTeXt folks, following [1] I do not get any PDF output running `context project.tex`. The product files are in a subfolder. I verified that first with [2] in a flat structure and then adding a subfolder where no output is created. Executing ConTeXt with the seperate product files as an argument works. $ context --version MTXrun | main context file: /context/tex/texmf-context/tex/context/base/context.mkiv MTXrun | current version: 2011.02.04 10:01 I attach the files. $ ls * env_mymag.tex project_mymag.log project_mymag.tex project_mymag.tuc prd_year2004-01: c_editorial.tex prd_year2004-01.tex Thanks, Paul [1] http://meeting.contextgarden.net/2007/share/sanjoy/sanjoy-typesetting-textb… [2] http://wiki.contextgarden.net/Project_structure

by Cecil Westerhof 24 Mar '11

I would like to use the date of the document in the generated PDF. (It is not interesting when the PDF is generated, but when the source was last changed.) How would I do this? -- Cecil Westerhof

Metfun macro for triangle
by Otared Kavian 24 Mar '11

24 Mar '11

Hi all, I have a document in which I must draw several triangles for which two summits, say z0, z1, and the length of the two other sides are known, so that the third summit, say z2, is completly determined. In order to draw one triangle the following works fine: \setupcolors[state=start] \starttext \startMPcode z0 = (0cm,0cm) ; z1 = (5cm,0cm) ; path p, q ; pickup pencircle scaled 2mm ; drawdot z0 ; drawdot z1 ; p := halfcircle scaled 8 cm ; % twice the length of the second side at z0 p := p shifted z0 ; q := halfcircle scaled 6 cm ; % twice the length of the second side at z1 q := q shifted z1 ; z2 = p intersectionpoint q ; drawdot z2 ; pickup pencircle scaled 1mm ; draw z0--z1--z2--cycle withcolor blue ; \stopMPcode \stoptext However I would like to have a macro, for instance named Triangle, which accepts four arguments z0,z1, length_1, length_2, so that in a MetaPost code i can use draw Triangle(z0,z1, 4, 3) withcolor blue ; in order to draw the above triangle. Has anyone any idea about how to do this? Thanks in advance for your help: OK

How to add a local texmf tree to context minimals?
by Ulrike Fischer 24 Mar '11

24 Mar '11

I would like to make some test of my virtual-lua-chessfonts with the context minimals. The files I want to test are in a small texmf trees. How can I add this trees to the list of trees used by context in a way that the changes are not lost after updates? -- Ulrike Fischer

search path for require(...)
by Ulrike Fischer 24 Mar '11

24 Mar '11

I'm trying to store the virtual lua chess fonts I'm currently creating so that latex and context can use them. 1. At first I stored the vf-chess-XX.lua in tex/luatex. This works for latex but not for context. tex/generic works for both. 2. My fonts loads a lua-file which should be shared by all fonts with chessfss=require('chessfss') latex finds the chessfss.lua without problems in various locations (e.g. tex/generic) but context not. How can I solve this problem? -- Ulrike Fischer
