Hello, The following code does not work, the second white ConTeXt is black !!! \setupbackgrounds[page][background=color,backgroundcolor=blue] \starttext {\rotate[rotation=90]{\definedfont[SansBold at 24pt]\white \ConTeXt}} {\definedfont[SansBold at 16pt] \white ConTeXt} \stoptext No problem if we replace white with red (or other color) in \definedfont[SansBold at 16pt] \red ConTeXt and no problem if we write \white\rotate[rotation=90]{\definedfont[SansBold at 24pt]\ConTeXt} I compile with TeXlive2013. Why is the white color different ? Thanks, Bertrand

matching font sizes with fallback fonts
by Pablo Rodríguez 01 Aug '13

01 Aug '13

Dear list, I’m trying to match the fallback font size with the lowercase size of the main font, as shown in this sample: \usemodule[simplefonts][size=90pt] \setmainfontfallback[GFS Neohellenic] [range={greekandcoptic,greekextended}, force=yes, rscale=auto] \setmainfont[TeX Gyre Pagella] \starttext aα γg AΑ ΒB \stoptext But rscale=auto doesn’t seem to work (if this is the right option). What am I doing wrong here? Many thanks for your help, Pablo -- http://www.ousia.tk

Math accents set too close to capital
by Michael Murphy 01 Aug '13

01 Aug '13

Hello all, I'm trying to typeset 'H' with a circumflex (or hat) in math mode, but the result is rather ugly when not using latin-modern. I've tried to redefine the \hat macro to move the accent up a bit using \topaccent: is this the best approach? Having to nest '$' does not seem right at all. (Also, for some reason although I find \mathhat in enco-ini.mkiv, when I try to use it I get undefined control sequence.) Thanks, Michael \starttypescript [mathfont] \definetypeface [mathfont] [mm] [math] [palatino] [default] [rscale=1.0] \stoptypescript \usetypescript[mathfont] \setupbodyfont[mathfont] \starttext $\hat{H}$ \def\hat#1{\topaccent{3pt}{0}{90}{\textcircumflex}{$#1$}} $\hat{H}$ \stoptext -- Michael Murphy murphy.md(a)gmail.com

Path problems w/ MkIV on Arch Linux
by Matt Gushee 01 Aug '13

01 Aug '13

Hello, Folks-- Once again I'm returning to ConTeXt after a long absence [maybe if I just kept using it I wouldn't have these problems?]. I'm trying to get started with MkIV; I don't feel a strong need to have the very latest code, so unless there are serious bugs, I want to use the version included with TexLive. At any rate, that's what I currently have and am trying to use. But I am running into issues with files not being found, e.g.: $ context --make mtxrun | unknown script 'context.lua' or 'mtx-context.lua' Yes, I ran mtxrun --generate first, though I am a bit confused as to whether I need to run that *and* luatools --generate, or just one or the other. Anyway, mtxrun --generate appears to work: $ mtxrun --generate .... resolvers | resolving | found configuration file '/usr/share/texmf-dist/web2c/texmfcnf.lua' .... system | lua | compiling '/var/cache/texmf/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/trees/5044cbe2799fe389b078f26ff6b9ee8e.lua' into '/var/cache/texmf/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/trees/5044cbe2799fe389b078f26ff6b9ee8e.luc' system | lua | dumping '/var/cache/texmf/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/trees/5044cbe2799fe389b078f26ff6b9ee8e.lua' into '/var/cache/texmf/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/trees/5044cbe2799fe389b078f26ff6b9ee8e.luc' stripped resolvers | caching | 'files' compiled to '/var/cache/texmf/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/trees/5044cbe2799fe389b078f26ff6b9ee8e.luc' This shows that mtxrun finds the correct configuration file--as far as I know, /usr/share/texmf-dist/web2c/texmfcnf.lua is the only instance of texmfcnf.lua on my system. And then it uses the value I have set in texmfcnf.lua to cache its output: TEXMFCACHE = "/var/cache/texmf", -- not used by context at all TEXMFSYSVAR = "$TEXMFCACHE", TEXMFVAR = "$TEXMFCACHE", So that's good. Yet the 'context' and 'luatools' commands can't find the lua scripts. Well, I hypothesized that $LUAINPUTS might be wrong, so I tried this: LUAINPUTS=/usr/share/texmf-dist/scripts/context/lua luatools --generate And it seems to work. However: LUAINPUTS=/usr/share/texmf-dist/scripts/context/lua context --make .... resolvers | resolving | using given filetype 'tex' resolvers | resolving | remembering file 'cont-en.mkiv' resolvers | resolving | using given filetype 'tex' resolvers | resolving | remembering file 'cont-en.tex' resolvers | formats | no tex source file with name 'cont-en' (mkiv or tex) resolvers | formats | using format path '/var/cache/texmf/luatex-cache/context/0399a8df3aef8d154781d0a9c2b8e28d/formats/luatex' resolvers | resolving | using given filetype 'tex' resolvers | resolving | remembering file 'cont-nl.mkiv' resolvers | resolving | using given filetype 'tex' resolvers | resolving | remembering file 'cont-nl.tex' resolvers | formats | no tex source file with name 'cont-nl' (mkiv or tex) system | total runtime: 0.239 So now the lua scripts are found, but the context macro files are not. At this point let me describe how my system is set up. As I said above, I'm attempting to use the ConTeXt that comes with TexLive. I've just upgraded TeXLive to the 2013 release, but that does not seem to affect these issues. Anyway, the executables are in /usr/bin; /usr/bin/mtxrun is the complete Lua script (i.e. not a symlink or any sort of stub), which appears to be identical to $TEXMF/scripts/context/stubs/unix/mtxrun. /usr/bin/luatools and /usr/bin/context also appear to be copies of their counterparts in the aforementioned stubs directory. The TeXLive packages for Arch provide the following trees: /usr/share/texmf /usr/share/texmf-dist /usr/share/texmf-config Almost everything important is now in /usr/share/texmf-dist, and there are no ConTeXt-related files in /usr/share/texmf. Accordingly, texmf.cnf contains the following definitions: TEXMFDIST = $TEXMFROOT/texmf-dist TEXMFMAIN = $TEXMFDIST TEXMFLOCAL = /usr/local/share/texmf;/usr/share/texmf So I have updated texmfcnf.lua to contain the following: TEXMFDIST = "selfautoparent:texmf-dist", TEXMFMAIN = "$TEXMFDIST", TEXMFLOCAL = "/usr{/local}/share/texmf", I'm not sure if that syntax is correct, but the definition of TEXMFLOCAL does not appear to affect the issues I'm concerned with here. Also, I should mention that my main reason for defining TEXMFLOCAL as I did (as well as TEXMFCACHE = /var/cache/texmf), is that I feel rather strongly (in keeping with what I understand to be 'Linux best practices') that files which are not managed by the Linux package manager should not be under /usr. But if by chance that is causing problems I don't absolutely have to do it that way. Anyway, somehow important files are not being found. Any suggestions? -- Matt Gushee

xmlfilter in lua
by Thomas A. Schmitz 01 Aug '13

01 Aug '13

Hi, hope this is comprehensible without a full example: I want to do some operations on my xml, and that's easier to do in Lua. However, I cannot find how to filter my results and pass them on to a command. In TeX, I would do this: \startxmlsetups xml:a \xmlfilter{#1}{/b/command(xml:command:b)} \stopxmlsetups \startxmlsetups xml:command:b \xmlconcat{#1}{/}\par \stopxmlsetups How would I do the same thing in Lua? Here's what I tried: function xml.functions.a(t) local b = lxml.filter(lxml.id(t), "/b") process(b) end function process(t) xml.xprint(t) end but that doesn't work yet, I get no results printed. So my question: what would be the right syntax in Lua? (And bonus points for: what is the equivalent of \xmlconcat ?) All best Thomas

Math fallback
by Aditya Mahajan 31 Jul '13

31 Jul '13

Is it possible to use the fallback mechanism for math fonts? For example, I am using Neo Euler for math which has a few missing glyphs. Can I use Cambria (or Xits) as a fallback font for missing glyphs. I am using the simplefonts module, but I am happy to write a typescript file if that makes things easier. I do not really want to define a new virtual font. Aditya

Change URL color to match layer

Questions about mathfence
by Aditya Mahajan 30 Jul '13

30 Jul '13

Hi, Some questions/remarks about math fences 1. When using \definemathfence[colorbracket][bar][middle=0x7C,color=red, command=yes] \starttext \startformula \colorbracket{\frac {a}{b}\fence a = b}^n \stopformula \stoptext The delimiter is of the wrong color (black instead of red), and the clause after \fence is red. I am doing something wrong or is it a bug. 2. For some types of expressions, for example, probability, the middle delimiter should have the space similar to mathrel, rather than mathord. For example, while typing I often use: \Pr\left( X = \frac {a}{b} \,\middle|\, Y = \frac{c}{d} \right) Would it be worthwhile to add these extra spaces by default (not sure what is the convention in physics/quantum mechanics for bra and ket notation) or as an option. 3. Finally, why are the default values of left, middle, and right = 0x2E. Isn't 0x7C a better default? Thanks, Aditya

Using backslash in chapter title.
by john Culleton 29 Jul '13

29 Jul '13

Using MKIV and MyriadProBold for my sanserif font I have the following chapter title: "Can You Type \bye?" which I type as \chapter{Can You type \backslash bye?} The slash appears but a bit low and much too thin. I have tried various games including creating a special font just for this character but nothing changes. the \backslash command seems invulnerable to change. Is there a way in MKIV to express a backslash in another way (bigger and bolder)? John Culleton

OSFONTDIR kills gui fonts.
by john Culleton 29 Jul '13

29 Jul '13

I am tryihg to follow the wiki on "Fonts in Luatex." It suggests the following statement for Linux systems: export OSFONTDIR="/usr/local/share/fonts;$HOME/.fonts" But I store my fonts in /usr/share/fonts so I used: export OSFONTDIR="/usr/share/fonts" The net effect of this statement was to wipe out all my text fonts used with XFCE4 or KDE, at least when I use my regular user signon. I examined my /etc/profile, $HOME/.profile, @HOME/.bashrc files and deleted or commented out all references to OSFONTDIR. I still have no gui fonts. If anyone has any suggestions on how I can revive my gui fonts that would be welcome. Only my regular user signon is affected, But I really want to know what kind of OSFONTDIR statement I can use that won't wipe out my gui fonts. I can of course move the pertinent fonts to the fonts directories in my /usr/local/texlive etc. file structure. But I am looking for a more general solution.

Opening quotes problem with context.
by john Culleton 27 Jul '13

27 Jul '13

Did a fresh install of context etc. from the context site. I used this test file: ------------------------------- \starttext ``Hello world.'' And ``Goodbye world.'' \stoptext %\bye ----------------------------------------- The resulting pdf shows two left tick marks for opening quotes but the closing quotes are proper curly quotes. If I modify the file as follows: ------------------------------- %\starttext ``Hello world.'' And ``Goodbye world.'' %\stoptext \bye --------------------------- and use luatex or pdftex from texlive the quotes are OK. I got similar results from context in texlive 2012 and texlive 2013. What is the proper code for opening quotes in context? I use slackware linux 14, the 64 bit version. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html
