Failure to Install minimals on iBook G3
by Robert Blackstone 19 Oct '10

19 Oct '10

Hello, I tried in vain to install the minimals on an old (2003) but still functional iBook G3, running under OSX 10.4.11. After having received some 4MB, I get the message: "dyld: incompatible cpu-subtype" plus a reference to line 103 of first-setup.sh. Does anybody on this list know what could be done about this. Btw, this iBook can handle TeX and ConTeXt. I installed MacTeX 2009 and everything works. But I would prefer the minimals. Thanks in advance. Robert Blackstone

\setuphead
by Herbert Voss 19 Oct '10

19 Oct '10

in http://wiki.contextgarden.net/Titles is an example for a wrong setting: \starttext \setuphead[section][textstyle=\em,textcommand=\WORD] \section{A not so long title} \stoptext the wiki sais, that this leads to \WORD{\EM A not so long title} which should give an error. However, the above works for me in the same way as \starttext \setuphead[section][textstyle=\em,deeptextcommand=\WORD] \section{A not so long title} \stoptext mkiv, TeXLive2010 Herbert

amssymb

Dear Sirs, I have a problem with displaying some special characters from the AMS Symbol-fontset, e.g. \blacksquare, \blacktriangle, ... The symbols are displayed under MkII but not under MkIV. (MkII and MkIV-version: 2010.05.24) The symbols are defined in "math-ent.lua", but how can I call this file to show the missing symbols? Is it possible to make a link to the now-non-existing Module "amsl" so I can use old ConTeXt-documents without changes? Thanks for your help Bernd Kosubek

duplex, marking
by kosubek com 19 Oct '10

19 Oct '10

Dear Sirs, I have trouble with \setuplayout[location=duplex] and \setuplayout[marking=color] (MkII-version: 2010.05.24 / MkIV-version: dito) A modified sample (from the ConTeXt-documentation "cont-en.pdf", section 1.6) will show the problem: \setuppapersize[B5][A4] \setuplayout[location=duplex,marking=color] \setuppagenumbering[alternative=doublesided] \starttext page 1 \page page 2 \page page 3 \page page 4 \stoptext The result are 4 pages on the left upper corner (--> odd pages) (MkII and(!) MkIV). instead of upper right/upper left (pages 1 and 2) upper right/upper left (pages 3 and 4). The option location={duplex,left} gives the same results. The color-bars are only displayed at MkIV, with MkII only the cropmarks are shown. Can anybody help me with the duplex option in MkiII and MkIV and getting color-bars in MkII? Thanks for your help Bernd Kosubek

problem with t-filter/t-vim
by Chen Shen 19 Oct '10

19 Oct '10

Hi Adityam, I am using the t-filter/t-vim module, and got stuck with two problems with it. 1. everything works fine if there is only one \definevimtyping declaration. However, if i declare two of them, as in the following: %%%%%%% \definevimtyping[PythonCode][syntax=python] \definevimtyping[CPPCode][syntax=cpp] \startPythonCode ... % Code A \stopPythonCode \startPythonCode ... % Code B \stopPythonCode %%%%%%% The counter for the temporary files is never incremented. So there is only "jobname-externalfilter-PythonCode-0.tmp" in the directory. Consequently, Code B appears twice in the produced PDF, while Code A never appears. 2. Every line in the Python code becomes a new paragraph in ConTeXt. I wonder if this could be changed. I am using \setupwitespace[line], so the spacing between two lines of source is too large. I am using the dev/ branch in the github repository. Thank you very much. regards, shenchen

What is the replacement for the 'stop_run' callback?
by Tad Ashlock 19 Oct '10

19 Oct '10

Hi All, I'm trying to update a ConTeXt module of mine. It does some data gathering during the ConTeXt run, and then processes it after the run is complete. This used to work last year: local id, err = callback.register('stop_run', new_stop_run_function) But now err is set to "callback 'stop_run' is frozen (actions performed at the end of a run)". I see from the mailing list archive that registering user callbacks was disallowed in February of this year (2010). I also saw some advice for installing other new user processing (like 'pre_linebreak_filter'), but no general advice for adapting to the lack of callbacks. ( http://archive.contextgarden.net/message/20100219.130524.b3857a0a.en.html) After trying various approaches for a couple of hours, I'm calling for help. :) Here's what I ended up with: \startluacode print('%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% TEST1') local function after_run (head, groupcode) print('%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% TEST2') return head, true end nodes.tasks.appendaction('finalizers','after','after_run') \stopluacode \starttext \input knuth \stoptext In the output, I see the TEST1 line, but not the TEST2 line. I don't know what "head" and "groupcode" are, but those seem to be the expected parameters for an action. I don't know why it returns "head, true", but that was recommended in a posting ( http://archive.contextgarden.net/message/20100410.005025.76ac9efd.en.html) I have no idea if 'finalizers' is the right parameter, but I didn't see any others that looked like it could be synonymous with 'stop_run'.

entries in registerentry
by Steffen Wolfrum 19 Oct '10

19 Oct '10

Hi, I don't understand the concept of entries in registerentry :o( Say, you have this example: \starttext \placeregister[index] \page page 1 \setregisterentry[index] [entries:1={eins}, entries:2={zwei}, entries:3={drei}, label=range] \page page 2 text \page page 3 \finishregisterentry[index][label=range] text \stoptext Why does only have entries:3 the index range "2-4", both entries:1 and 2 are emtpy? What should I write in order to have all of those entries referering to the same "2-4"? Best, Steffen

quoted environment arguments
by Philipp Gesang 18 Oct '10

18 Oct '10

Hi, there’s a behaviour concerning how context handles forced quotes in command line arguments that I do not understand. ··· <example> ··················································· for i=-1,#environment.rawarguments do print(i, environment.rawarguments[i], environment.originalarguments[i]) end ·· </example> ··················································· Now run this as ‘test.lua’ with mtxrun: # mtxrun --script test.lua \"simple\" \"more complex\" Here I get the following output: ··· <result> ···················································· -1 texlua texlua 0 /home/kokytos/context/tex/texmf-linux/bin/mtxrun /home/kokytos/context/tex/texmf-linux/bin/mtxrun 1 --script --script 2 test.lua test.lua 3 "simple" simple" 4 "more more complex 5 complex" nil ·· </result> ···················································· Number 3 indicates that a quoted argument is fully unquoted iff it gets parsed into multiple arguments. It also leads to ‘Unbalanced quotes in argument ./simple"’ when used with the main ‘context’ script. It would make sense if you expect only args containing spaces to be explicitly quoted, though. I would propose a patch like the one I attached but I’m having difficulties testing locally modified copies of the core Lua files, so it remains untested. Philipp
