Hi is there a way for \prime not get smaller when used with sub/superscripts? Or realigned somehow? Without font changes would be nice. \starttext \startformula \frac13T\prime_{rs}T\prime_{st}T\prime_{tr} \stopformula \startformula \frac13T_{rs}\prime T_{st}\prime T_{tr}\prime \stopformula \stoptext Thanks YT

Thanks, Hraban, for your advice. I’ve no idea whether or not the error is connected with “too many open files”. The Project needs some 40 files but its working directory contains some 120 files (most of them only for testing purposes). Moreover, I usually only have the “project-file" open during processing (but I don’t know if that is important here). Surprisingly, as I wrote in my first post on this subject, the error up till now only occurs when I use interaction, and it usually does not occur anymore, at least on the same day, after I processed it once without interaction. But the next day, after sleep (of the Mac), the error may occur again. I did not change the settings but I will in case the problem gets worse. Best regards, Robert

Span all columns in natural tables
by Christoph Reller 23 Sep '14

23 Sep '14

Hi, Is it possible to define a cell that spans all columns without knowing beforehand how many columns there are? Specifically I would like to do something like this: \starttext \bTABLE \bTR \bTD[nc=<all>] I span all the columns \eTD \eTR \bTR \bTD col 1 \eTD \bTD col 2 \eTD <...> \bTD col n \eTD \eTR \eTABLE \stoptext Is there any expression for <all> that yields the total number of columns? I tried to use \tablecellcolumns but it is undefined if used at this location. Thank you for any feedback! Christoph Reller

s-mod produces "system > error: invalid parameter ..."
by Christoph Reller 21 Sep '14

21 Sep '14

Hi, Probably this is a minor thing. When processing the following module template: %D \module[ %D file=p-Mymod, %D title=The Mymod Module, %D author=The Author, %D date=\currentdate, %D ] %M \usemodule[Mymod] %D Hello \writestatus{loading}{ConTeXt User Module / Mymod} \unprotect \protect \endinput with: context --ctx=s-mod p-Mymod.mkiv then the console output contains: system > error: invalid parent type for parametercommand, type defined too (best check it) The output module documentation is, however, produced correctly. I assume that this is harmless, but it would be nice if the log file contained no "error" message if the processing was successful. Thank you for any feedback, Christoph Reller

Two general questions arise (if your permit): 1. Where are the key-value pairs stored? In your first solution you handle the key setting by explicitly calling lua on every \setup<name> call. It seems that all key-value pairs (that are set with \installcommandhandler-generated \setup<name>) are stored on the TeX side and not on the lua side. Is this correct? 2. Calling \ctxlua from lua. I was tempted to add another level of indirection to your second (the "synchronize") solution. I.e: in the lua code (in a separate lua file to avoid the do ... end introduced by \startluacode ... \stopluacode) I have: n = "" v = "" function getkey(name,value) n = name v = value end function myfun(parameters,content) context([[\ctxlua{getkey("gkey","\elemparameter{gkey}")}]]) context(" name=") context(n) context(", value=") context(v) end The above does not work because the value obtained "lags behind", i.e. initially v will be "", on the second call v will have the value of the first \setupelem[gkey=gval], and so on. I guess this lag is due to the way TeX and lua communicate to each other? A small question: What do you mean by "there is no grouping in lua"? Thank you anyway for your valuable input.

Influencing the vertical spacing of the table of contents?

Main or Overall Index of a series of volumes
by Rudolf Bahr 20 Sep '14

20 Sep '14

Hello All, just to plan in advance: I'd like to construct a main or overall index out of the indices of a series of rather big volumes with their own page numbering from 1 to (say) 1000. Of course the intended main or overall index should point not only to a page number, but to the corresponding volume number or title too. Is that fundamentally possible and if yes how? Greetings, Rudolf

perfect centering of layers in a text area

Hello, I'm converting some context from mkii to mkiv. Since the definelogo is depreciated I try to use layers to get the same result.

How to get parameters in lua
by Christoph Reller 19 Sep '14

19 Sep '14

Hi, \installcommandhandler nicely provides (among others) \define<name> and \setup<name> commands. Thus it is easy to provide a key with \setup...[key=value] and to read the value of such a key with \<name>parameter{key}. My question is: How do I read the value of a key defined with \setup...[key=value] on the lua side? If I use context.<name>parameter("key") then the value of key is printed directly. I want to be able to read that value and use it in lua with something like myvariable = context.?whatfunction?("key") Here is some example code: \unprotect \startluacode function myfun(parameters,content) context("From lua: Parameters: ") context(parameters) context.elemparameter("gkey") -- directly prints the parameter context.par() end \stopluacode \installnamespace{elem} \installcommandhandler \????elem {elem} \????elem \appendtoks \setuevalue{\currentelem}{\elem_cmd{\currentelem}}% \to \everydefineelem \unexpanded\def\elem_cmd#environment{% \edef\currentelem{#environment}% \dosingleempty\elem_cmd_parameters} \def\elem_cmd_parameters[#parameters]#content{% \setupcurrentelem[#parameters] From \TeX\: Parameters: key=\elemparameter{key}, gkey=\elemparameter{gkey}\par \ctxlua{myfun(\!!bs#parameters\!!es,\!!bs\normalunexpanded{#content}\!!es)} } \defineelem[base] \setupelem[gkey=gval] \protect \starttext \base[key=val]{Hello} \stoptext Thank you for any feedback, Christoph Reller

Permissible characters in ConTeXt reference labels
by Mark Szepieniec 18 Sep '14

18 Sep '14

I'm trying to fix a problem in pandoc (see https://github.com/jgm/pandoc/pull/1589) where it doesn't properly sanitize the reference labels in ConTeXt output, causing errors during compilation when a label contains '#' for example. Note that this sanitizing is needed in addition to the regular backslash escaping used for control characters: '\#' is still illegal in a label for example. In the sanitizer function I'm writing, I'd like to properly escape all illegal characters, but I couldn't find an explicit list of allowed or illegal characters. Based on some testing I've conducted (see attached file), I've arrived at the following set: \#[]",{}%()|= 1) Does this look like a reasonable set? Are there other characters or sequences that should be included, or are worth testing? 2) I was told (see https://groups.google.com/forum/#!topic/pandoc-discuss/tYpXMUkmbEY) that if the characters " and , didn't work, it would count as a ConTeXt bug, is there any truth to that? Please let me know if any further info is needed on my part. 3) Does anyone see issues with this general approach? I'm relatively new to ConTeXt, so I might be missing either a huge problem, or an obviously easier way to do this. Thanks, Mark

Erratic error message
by Robert Blackstone 17 Sep '14

17 Sep '14

Hi all, When typesetting my project with interaction, sometimes the processing stops after a few runs with an error message that points at an empty line in one of the chapters that normally gives no trouble. For interaction this setup is used: \setupinteraction[state=start,focus=standard,style=,color=blue,contrastcolor=] \placebookmarks[prechapter,chapter,section][prechapter,chapter,section][number=no] When I comment out the first of these two lines, in other words, without interaction, the project is processed without any problem. Sometimes, unfortunately not always, when I immediately repeat the processing with interaction, all goes well. So what is my problem? Not understanding what might be wrong, and not being able to correct things gives me a feeling of insecurity, trusting Murphy’s law to make sure that processing will fail when my deadline is approaching fast.

Gallery of fonts
by Procházka Lukáš Ing. - Pontex s. r. o. 16 Sep '14

16 Sep '14

Hello ConTeXtists, there are many fonts distributed with Ctx standalone (minimals). I'd like to create a "gallery" (or "preview") of fonts - one font per page (A4) with all its "kinds" (italic, bold, semibold; ss, rm, hw atc.), and a couple of sizes (10, 11, 12, 16, 24 pt). Is there a way how to create such gallery, which would walk through Ctx fonts directory (on my machine: c:\ConTeXt\tex\texmf\fonts\*) automatically? - This would allow user to have a better overview over AVAILABLE fonts and their LOOK; and the code for the gallery generator would help user to see how to use/access fonts in a Ctx document. Thanks in advance. Best regards, Lukas -- Ing.

lpdf.checkedkey has problem with false values
by Michail Vidiassov 16 Sep '14

16 Sep '14

Dear Developers and All, lpdf.checkedkey routine from lpdf-ini.lua has problems with accessing false boolean values, it returns them as nil. Is it by design or neglect? (I vaguely remember stumbling on this problems before, so there is a chance that I have already got the answer, but have forgotten it.) The minimal demo: \starttext \startluacode local function writebool(bv,text) if bv == true then io.write(text, " true \n") elseif bv == nil then io.write(text, " nil \n") else io.write(text, " false\n") end end local a = {} a["x"] = true a["y"] = false a["z"] = nil writebool(lpdf.checkedkey(a,"x","boolean"),"lpdf.checkedkey(a,\"x\",\"boolean\")") writebool(lpdf.checkedkey(a,"y","boolean"),"lpdf.checkedkey(a,\"y\",\"boolean\")") writebool(lpdf.checkedkey(a,"z","boolean"),"lpdf.checkedkey(a,\"z\",\"boolean\")") writebool(a.x,"a.x") writebool(a.y,"a.y") writebool(a.z,"a.z") \stopluacode TEST \stoptext It results in the following relevant output lpdf.checkedkey(a,"x","boolean") true lpdf.checkedkey(a,"y","boolean") nil lpdf.checkedkey(a,"z","boolean") nil a.x true a.y false a.z nil Note that false value was read by checkedkey as nil. Sincerely, MIchail

Scientific paper boiler plate
by Kip Warner 15 Sep '14

15 Sep '14

Hey list, I'd like to write a short scientific paper describing an algorithm I discovered in the realm of computational geometry a few years ago before I forget it entirely. I've been meaning to do this for some time, but haven't had a chance. I'd like to use ConTeXt. Does anyone have a sample source I could take a look at as a starting point? I will need to typeset some figures, pseudo code, references, etc. and this all takes much less time when someone much more clever than I, like Wolfgang or Hans already has a similar environment file and such setup. Respectfully, -- Kip Warner -- Senior Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

problem with buffer
by Kenny 15 Sep '14

15 Sep '14

I'm writing a module to typeset problems/tests. Depending on a flag, solutions are either displayed or not. If the solutions are not displayed, I want to give a certain amount of empty vertical space for the student's work. This is where my difficulty begins. The typesetting works with the solutions displayed (\def\examshowsolutions} {yes}) but not with the empty vertical space (\def\examshowsolutions{no}). I get an "Emergency stop" that I cannot figure out. Here's the code for a minimal example of my difficulty.. \def\setupsolutions{ \doifelse{\examshowsolutions}{yes} {\defineenumeration[SOLUTION] % display the solutions [text=\Word{solution},number=no, after={\vskip1ex}]} {\definebuffer[SOLUTION] % hide solutions, \setupbuffer[SOLUTION][local=yes]} } \def\startsolution{\dosingleempty\dostartsolution} \def\dostartsolution[#1]{ \getparameters[solution][height=1em,] % set defaults (needed in case parameters missing) \iffirstargument \writestatus{DEBUG}{--First argument: |#1|} \getparameters[solution][#1,] \fi \writestatus{DEBUG}{--\solutionheight--} \startSOLUTION \writestatus{DEBUG}{--dostartsolution...finished} } \def\stopsolution{ \stopSOLUTION \writestatus{DEBUG}{--dostopsolution...1} \doif{\examshowsolutions}{no}{\godown[\solutionheight]} \writestatus{DEBUG}{--dostopsolution...finished} } \starttext \def\examshowsolutions{no} % control whether solutions are displayed \setupsolutions \startsolution % test without vertical height specified Here is a solution. \stopsolution \startsolution[height=5em] % test with vertical height specified Here is another solution. \stopsolution \stoptext The error occurs with the \startSOLUTION command.

centering a makeup
by Pablo Rodriguez 15 Sep '14

15 Sep '14

Dear list, I have the following sample: \definemakeup [custom] [location=middle, width=.5\textwidth] \starttext \startmakeup [custom] \input ward \stopmakeup \stoptext How can I center the makeup in the page? \definemakeup[custom][align=middle] centers the lines, but this is something different. It is not a question of paragraph orientation. It is rather a question of placing the makeup in the middle of the page (also horizontally) Many thanks for your help, Pablo -- http://www.ousia.tk
