beta
by Hans Hagen 08 May '16

08 May '16

Hi, I uploaded a beta. This one has an (partially) alternative loader for type one files so that we can apply features as with open type fonts (node mode). I didn't test it extensively but I dont' expect many problems either.

searching in subdirectories with project structure
by Javier M Mora 06 May '16

06 May '16

Hi, (this is my first email to the list) I've created a project for my Thesis. The file tree is: /prod_thesis/ /prod_thesis.tex /envi_thesis.tex /comp_chap1/ /comp_chap1.tex /envi_chap1.tex /images/ /image1.jpg /image2.jpg (...) /tables/ /table1.tex /table2.tex (...) /comp_chap2/ /comp_chap2.tex /envi_chap2.tex /images/ /image1b.jpg /image2b.jpg (...) /tables/ /table1b.tex /table2b.tex (...) (...) envi_chap1.tex has: \startenvironment envi_chap1 \product prod_thesis \usepath[images] \usepath[tables] \stopenvironment comp_chap1.tex has: \startcomponent comp_chap1.tex \product prod_thesis \environment envi_chap1 blah blah blah \placefigure[here][fig:img1]{img1}{ \externalfigure[image1.jpg] } blah blah blah \input tables/table1 blah blah blah \stopcomponent prod_thesis.tex has: \startproduct prod_thesis \environment envi_thesis blah blah blah \component comp_chap1 \component comp_chap2 (...) \stopproduct and finally, envi_thesis.tex has: \startenvironment envi_thesis \usepath[{comp_chap1,comp_chap2}] blah (about styles) blah \stopenvironment If I cd into comp_chap1 dir and exec: texexec -xtx comp_chap1.tex the chapter1 is generated without any problem. All images and tables are inserted ok. But if I cd into prod_thesis and exec: texexec -xtx prod_thesis.tex all images are replace by "dummy images", and tables are not found (raising an error in compilation of document). In prod_thesis compilation (is it correct to say "compilation of document"?), context is looking for file /prod_thesis/tables/table1.tex but isn't not looking in /prod_thesis/comp_chap1/tables/table1.tex. I've created a copy of tables in /prod_thesis/ and document compiled good. But i don't like to pollute prod_thesis directory. Questions: What is the canonical way to keep subdirectories of dependencies in a component? (to be reused later in product compilation) I thought \usepath was to indicate where look for input files. I have to use "\input tables/table1" to find table 1. \usepath didn't work in envi_chap1.tex. Cheers.

Duplex printing problem!
by Geert Verhaag 05 May '16

05 May '16

Hi, I try something like this: *\definepapersize[BOOK][width=270mm,height=195mm]** **\setuppapersize[BOOK][A4,landscape]* while my *\setuplayout* command contains: *location={doublesided,left}* among other settings. I would expect that the BOOK-page on the front and back side would move to the correct corner, but that doesn't seem to happen. Both on the front and back are shifted to the left!? I'would expect them to alter position between left and right! What am I doing wrong? Regards, Gerard Verhaag By the way running context --version yields the following info: mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /home/verhaag/context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2013.08.11 20:23

Handling Semi-Bold for Minion Pro in Context (LuaTeX)
by Antoine Cailliau 04 May '16

04 May '16

Hello, I'm trying to use the font Minion Pro for my document. I'm using the simplefont module but I cannot use the semibold font. I guess I'm missing some line in the configuration to bind sb to the semibold variant. Here is a short example of my setup: \definefontalternative[sb] \definefontalternative[sbi] \definefontfeature[default][default] [mode=node, script=latn, kern=yes, palt=yes, tlig=yes, trep=yes, init=yes, size=yes] \definefontfeature[frac][default][frac=yes] \definefontfeature[sups][default][sups=yes] \definefontfeature[onum][default][onum=yes] \definefontfeature[lnum][default][lnum=yes] \definefontfamily [myfamily] [serif] [MinionPro] \definefontfamily [myfamily] [sans] [MyriadPro] \setupbodyfont [myfamily] \define[1]\sup{\feature[+][f:superscript]#1} \defineparagraphs[TwoColumns][n=2, align={hz, hanging}] \setupparagraphs[TwoColumns][1][width=100pt, style=italic, align=left] \starttext \startbuffer[Plato] How you, O Athenians, have been affected by my accusers, I cannot tell; but I know that they almost made me forget who I was--so persuasively did they speak; and yet they have hardly uttered a word of truth. \stopbuffer \startTwoColumns Roman\TwoColumns \getbuffer[Plato] \stopTwoColumns \startTwoColumns Italic\TwoColumns {\it\getbuffer[Plato]} \stopTwoColumns \startTwoColumns Semi bold\TwoColumns {\sb\getbuffer[Plato]} \stopTwoColumns \startTwoColumns Bold\TwoColumns {\bf\getbuffer[Plato]} \stopTwoColumns \startTwoColumns Semi bold italic\TwoColumns {\sbi\getbuffer[Plato]} \stopTwoColumns \startTwoColumns Bold italic\TwoColumns {\bi\getbuffer[Plato]} \stopTwoColumns \stoptext Any help is deeply welcome, Antoine

font features in math
by Ulrike Fischer 04 May '16

04 May '16

When I compile this in context all number are oldstyle numbers: \starttext \font\test= {name:TeX-Gyre-Termes:+onum} \test 0123456789 $\fam0 \textfont0=\test 0123456789$ \stoptext When I run a similar plaintex (or latex) example in texlive 2016 with a new luaotfload then the text numbers are (as wanted) old style, but the numbers in math mode are lining numbers (the font is correct): \input luaotfload.sty \font\test= {name:TeX-Gyre-Termes:+onum} \test 0123456789 $\fam0 \textfont0=\test 0123456789$ \bye So somehow in math the +onum is lost in plain and latex but not in context. What is context doing differently to avoid this? (It can't be the fontloader. I forced luaotfload to use the context files from the minimals.) -- Ulrike Fischer http://www.troubleshooting-tex.de/

[lhf@tecgraf.puc-rio.br: [ANN] ltokenp, a token processor for Lua]
by Philipp Gesang 04 May '16

04 May '16

Hi Hans, all, this was just announced on lua-l. Might be relevant to Context since the advertised functionality intersects with mtx-package / util-mrg.lua: Potential uses include: - Compressing Lua programs by removing comments and whitespace (strip.lua) - Removing assertions (assert.lua) - Adding new syntax sugar (self.lua) - Experimenting with new syntax without hacking the Lua source (reserved.lua) I especially like the idea of having some kind of a preprocessor. The original announcement can be found at Gmane in case the attachment is eaten by the list: http://thread.gmane.org/gmane.comp.lang.lua.general/121329 Have fun, Philipp ----- Forwarded message from Luiz Henrique de Figueiredo <lhf(a)tecgraf.puc-rio.br> ----- Date: Wed, 4 May 2016 02:17:22 -0300 From: Luiz Henrique de Figueiredo <lhf(a)tecgraf.puc-rio.br> To: lua-l(a)lists.lua.org Subject: [ANN] ltokenp, a token processor for Lua User-Agent: Mutt/1.5.20 (2009-12-10) ----- End forwarded message ----- ltokenp is now available at http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/5.3/ltokenp.tar.gz It should work for Lua 5.1, 5.2, and 5.3. The README is attached. Enjoy. All feedback welcome. --lhf ltokenp is a token processor for Lua: it allows you to process the stream of tokens coming from the Lua lexer. Potential uses include: - Compressing Lua programs by removing comments and whitespace (strip.lua) - Removing assertions (assert.lua) - Adding new syntax sugar (self.lua) - Experimenting with new syntax without hacking the Lua source (reserved.lua) ltokenp accepts Lua scripts to run and files to process. The scripts and files are executed and processed as seen. Each script appears as a separate argument after '-s', one '-s' per script. Scripts typically output the contents of the files with some modifications. Unfortunately, all comments and whitespace are eaten by the lexer and never reach the token stream. A typical usage is ltokenp -s script.lua [file.lua ...] but you can also do ltokenp -s s1.lua f1.lua -s s2.lua f2.lua A global function named FILTER will be called once for each token seen in the files. So, scripts typically define FILTER. If no scripts are given, ltokenp just dumps the token stream with this: function FILTER(line,token,text,value) print(line,token,text,value) end As can been above, the FILTER function receives 4 arguments from the lexer: - the line number where the token appears - the token as a number - the token as text - the value of names, numbers, and strings; for other tokens, the value is the same as the text. To try ltokenp, just edit Makefile to reflect your installation of Lua and then run make. This will build ltokenp and run a simple test. Note that ltokenp needs inside information from the Lua private headers and so it needs to be built using a Lua build directory, not just the usual installation directories. This code is hereby placed in the public domain. Please send comments, suggestions, and bug reports to lhf(a)tecgraf.puc-rio.br .

Garamond Premier Pro font goodies file
by massifr＠fastwebnet.it 03 May '16

03 May '16

Hello list, I'm using the Adobe Garamond Premier Pro font. It has 4 optical sizes: Caption, Normal, Subhead, Display. I tried to modify ebgaramond.lfg to adapt it to Garamond Premier Pro. You find it as an attachment. I don't know how to use that goodies file to see the different optical sizes in a document. I've tried this: \loadfontgoodies[GaramondPremierPro] \definefontfamily [default] [rm] [tf=name:GaramondPremierPro-Regular, it=name:GaramondPremierPro-Italic] \setupbodyfont[default,12pt] \dostepwiserecurse {6} {22} {1} { \definebodyfontenvironment[default][#1pt][text=#1pt,em=italic] } \starttext \dostepwiserecurse {6} {22} {1} { \switchtobodyfont[#1pt] \purefontname\font: \input tufte \blank } \stoptext but it does not work. Any help? Thanks in advance, Massi To Hans: if you find it useful for Context, you can add and/or modify it to the distribution. You can also change the author to yourself.
