mtxrun --script server help broken
by Thomas A. Schmitz 16 Sep '13

16 Sep '13

Hi, was trying to use the help server this morning while I was offline, and it doesn't work, AFAICS. Here's the error: mtx-server | running at port: 31415 mtx-server | document root: /mnt/shared/context/tex/texmf-context/scripts/context/lua mtx-server | main index file: unknown mtx-server | scripts subpath: /mnt/shared/context/tex/texmf-context/scripts/context/lua mtx-server | context services: http://localhost:31415/mtx-server-ctx-startup.lua mtx-server | request from: 127.0.0.1 mtx-server | request data: GET /mtx-server-ctx-startup.lua HTTP/1.1 mtx-server | requested url: /mtx-server-ctx-startup.lua mtx-server | requested action: /mtx-server-ctx-startup.lua mtx-server | performing action: /mtx-server-ctx-startup.lua mtx-server | locating script: /mnt/shared/context/tex/texmf-context/scripts/context/lua/mtx-server-ctx-startup.lua mtx-server | loading script: /mnt/shared/context/tex/texmf-context/scripts/context/lua/mtx-server-ctx-startup.lua mtx-server | return type: function mtx-server | saving script: function mtx-server | running script: /mnt/shared/context/tex/texmf-context/scripts/context/lua/mtx-server-ctx-startup.lua mtx-server | time spent with client: 0.000 seconds mtx-server | request from: 127.0.0.1 mtx-server | request data: GET /favicon.ico HTTP/1.1 mtx-server | requested url: /favicon.ico mtx-server | requested action: /favicon.ico mtx-server | performing action: /favicon.ico mtx-server | requested file '/favicon.ico' mtx-server | handling error 404: Not Found mtx-server | time spent with client: 0.000 seconds mtx-server | request from: 127.0.0.1 mtx-server | request data: GET /mtx-server-ctx-help.lua HTTP/1.1 mtx-server | requested url: /mtx-server-ctx-help.lua mtx-server | requested action: /mtx-server-ctx-help.lua mtx-server | performing action: /mtx-server-ctx-help.lua mtx-server | locating script: /mnt/shared/context/tex/texmf-context/scripts/context/lua/mtx-server-ctx-help.lua mtx-server | loading script: /mnt/shared/context/tex/texmf-context/scripts/context/lua/mtx-server-ctx-help.lua mtx-server | return type: nil mtx-server | handling error 404: Not Found mtx-server | time spent with client: 0.000 seconds mtx-server | request from: 127.0.0.1 mtx-server | request data: GET /favicon.ico HTTP/1.1 mtx-server | requested url: /favicon.ico mtx-server | requested action: /favicon.ico mtx-server | performing action: /favicon.ico mtx-server | requested file '/favicon.ico' mtx-server | handling error 404: Not Found mtx-server | time spent with client: 0.000 seconds From time to time, it's wonderful to have offline help (and I still miss Patrick's emacs etexshow...)

Updating modules with a ppa:reviczky/context-daily installation
by Michael Ash 03 Aug '13

03 Aug '13

I have a question about how to update context modules. In earlier correspondence Question: I am still having a problem with...[the letter module] Answer: This is now fixed... I use a context installation managed by ubuntu/apt-get from the Personal Package Archive *ppa:reviczky/context-daily* ( https://launchpad.net/~reviczky/+archive/context-daily). The current version is: ConTeXt ver: 2013.07.24 14:11 MKIV beta fmt: 2013.7.31 int: english/english How is it possible to (1) tell which version of a module is installed? (2) update a module to the latest version? Because I use the PPA version, I have not used first-setup.sh. I have only a limited understanding of where the context supporting material is maintained. Thank you very much for your guidance. Best, Michael PS Thank you very much for the guidance on the correspondence documentation and the reference line alternatives in the letter module > BTW are the values for the "alternative" key ("example", "e", "c", etc.) documented somewhere? You can look at the predefined arguments in the old manual which is available online: https://bitbucket.org/wolfs/correspondence/downloads.

Something weird with white color
by Bertrand Masson 01 Aug '13

01 Aug '13

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

wrong \setupinteraction[focus=standard]?
by Pablo Rodríguez 01 Aug '13

01 Aug '13

Dear list, I’m trying to get internal links to footnotes without having the focus changed. I try this minimal sample: \setupinteraction[state=start,focus=standard] \starttext Body text\footnote{Footnote.}. \stoptext But I cannot get it working (it should work, according to the wiki). Is this a bug? Many thanks for your help, Pablo -- http://www.ousia.tk

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
