Duplex printing problem!
by Geert Verhaag 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?

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.

Autogenerating a module's documentation
by Mohammad Hossein Bateni 01 May '16

01 May '16

Hello list, Has anyone managed to generate documentation for lua files recently? According to wiki/Module <http://wiki.contextgarden.net/Modules>, something like the following should work: context --ctx=x-ldx core-con.lua But it only produces core-con.lua.prep and not the PDF file. In fact, it seems to work on the prep file and compile a core-con.lua.prep.prep which escapes even the XML tags of the prep file. Probably some switch changed and the ctx file was not updated, so it just doesn't know how to deal with the prep file properly? On the other hand, the command to get PDF documentation out of TeX files does work and produces (albeit with some errors at times) the final documentation. context --ctx=s-mod core-con.mkiv Thanks! —MHB

RTL \definedescriptions
by Mohammad Hossein Bateni 01 May '16

01 May '16

Hello Hans and Wolfgang, I tried different options in \definedescription and compared LTR and RTL behavior. There are certain inconsistencies/bugs in the RTL setting. Attached you can see a TeX file and the resulting PDF, trying different options. The first two pages consider different parameters in the LTR setting and then the same come in the RTL environment. In the following I use alt instead of alternative. Here are the issues I noticed: 1) Why isn't the head text consistently mirrored in the RTL environment? It happens only in alt=serried. 2) Option hang=2 produces a strange result for RTL. The hanging part appears on the opposite side of the head text, which somehow pushes the head text outside the text area. 3) Option alt=top for RTL still puts the head text on the left-hand side. 4) I expect the LTR and RTL versions of the same settings to mirror one another, but they do not. Although LTR/alt=left and RTL/alt=right look pretty similar (and so do LTR/alt=right and RTL/alt=left), but these pairs do not mirror one another. In particular, there is some space to the right of the head text in LTR/alt=right, while there is none to the left of LTR/alt=left. The same thing shows in the margin alternatives where the distance between the head text and the body is different in RTL and LTR. —MHB

Dear list, I have the following sample, \setuppapersize[A5][A4, landscape] \setuparranging[2UP] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \startbuffer[hola] \mainlanguage[es] \starttext \dorecurse{32}{\input cervantes-es\par} \stoptext \stopbuffer \starttext \typesetbuffer[hola] %~ \insertpages[{\typesetbuffer[hola]}][width=Opt] \stoptext Is there any way to make the commented \insertpages command work? Or is there any way to force the PDF file name in \typesetbuffer? Many thanks for your help, Pablo -- http://www.ousia.tk
