TeX expansion within lua
by Marco Patzer 05 Sep '12

05 Sep '12

Hi, please have a look at the following example: \starttext \def\cmd{% \def\mymacro{Foobar} \newtoks\mytoks \mytoks={mytoks}} \startluacode context.cmd() context.mymacro() -- this fails -- context(tex.toks.mytoks) \stopluacode -- this works \startluacode context(tex.toks.mytoks) \stopluacode \stoptext Why does the first call to tex.toks.mytoks fail? Apparently the luacode environment has to be closed for cmd to be expanded. I guess that the call to mymacro() succeeds is a quirk due to the face that the macro is expanded later, in contrast to tokens, dimens and counters. Is there a command I can use within Lua to expand a macro immediately or to expand the pending macros to be able to access the values like the token register in the example? Another question which is related: Is there a way to access the contents of the macro from within Lua like counters and token registers? \starttext \newtoks\mytoks \mytoks={Foobar} \startluacode local tok = tex.toks.mytoks -- something like this is what I have in mind -- local mac = tex.macros.somemacro \stopluacode \stoptext I am just interested in a text string, not a box with typeset material. I guess that's more difficult, since macros are expanded and not just simply read. Marco

Lua conditionals fail inside \starttexdefinition
by Marco Patzer 05 Sep '12

05 Sep '12

Hi, I discovered strange behaviour concerning Lua conditionals within texdefinitions. ConTeXt complains: 'then' expected near 'thenelseend'. I guess it has something to do with how the content of a texdefinitions is grabbed. Seems like a bug or is this by design? % This works fine \def\mycmd{% \startluacode if true then else end \stopluacode} % This one fails % \starttexdefinition mycmd % \startluacode % if true then % else % end % \stopluacode % \stoptexdefinition \startluacode userdata = userdata or { } function userdata.myfun() if true then else end end \stopluacode % This also works fine \starttexdefinition mycmd \luacode{userdata.myfun()} \stoptexdefinition \mycmd Marco

Setting options for every n-th row in natural TABLEs
by Aditya Mahajan 05 Sep '12

05 Sep '12

Hi, On Edward Tufte's website, there is a discussion on zebra coloring in tables[1]. One of the suggestion is to add a horizontal rule after every third line or shade three lines with one background color and the remaining three with another background color. Is there an easy way to do this with natural TABLEs? I can do something like: \setupTABLE[row][1,2,3][background=color, backgroundcolor=gray] \setupTABLE[row][7,8,9][background=color, backgroundcolor=gray] but it requires knowing the number of lines in advance.

\startluacode and macro names with underscores
by Marco Patzer 04 Sep '12

04 Sep '12

Hi, the luacode environment chokes on macro names with underscores. Example: \starttext \unprotect \def\number_two{two} \startluacode userdata = userdata or { } function userdata.number_one() context("one") end -- works userdata.number_one() -- fails -- context.number_two() -- workaround tex.print("\\number_two") \stopluacode \protect \stoptext Why is that and what can be done to access underscored macros in the usual way? I guess it's some catcode change from the function that prints into the TeX stream. Marco

Component: \product, \project
by Procházka Lukáš Ing. - Pontex s. r. o. 04 Sep '12

04 Sep '12

Hello, when looking at http://wiki.contextgarden.net/Project_structure - - why \product and/or \project specification is used in the COMPONENT in the example, or why is it supposed or even required to use in components? I imagined that component doesn't need to know in which project/product is used, even when in may be intended to more projects/products. So does it mean I would have to enumerate all projects/products in which the component is to be used? Or can be \product and/or \project specification omitted in the component?

Stretching width in natural TABLEs
by Aditya Mahajan 04 Sep '12

04 Sep '12

Hi, Is it possible to stretch the widths of each column in natural TABLEs, so that the widths are in a certain propotion? For example, suppose I have a table with three columns and I want to set the width of the first column to a fixed amount, and split the remaining space between columns two and three in a 1:2 ratio. Extreme tables implement something similar using option={stretch, width}, but AFAIU, it is not possible to fix the width of a particular column. Aditya

Divided cells and bullet points in tables
by Malte Stien 01 Sep '12

01 Sep '12

Hi, I'm trying to create a table with the following formatting: 1. The top left cell is divided in two by a diagonal line with separate text into each triangle 2. Another cell in the table body has a bulleted list I've had no success with the first. With the second I've tried using the \startitemize command. It generates the bullet points but places all the items on a single line and hence pushing the table wider than the page. I've also tried using \par or \newline but to no avail. I have been using tabulate for the table; is there another table library that might make this work? Any help would be much appreciated. Thank you, Malte.

Margin text and multiple columns

Hello, I have a problem with margin texts in combination with multiple columns using mkiv. I want to set a text in the outer margin of a double sided document. This works well using \inouter as seen in the following document: --- \setuppagenumbering[alternative=doublesided] \starttext \inouter{Text in Margin} \input knuth \page[yes] \inouter{Text in Margin} \input knuth \stoptext --- But fails, when I use it in combination with multiple columns. Then the margin text of the odd pages is set in the second column (probably in the margin of the first column) instead of the margin of the whole page. --- \setuppagenumbering[alternative=doublesided] \starttext \inouter{Text in Margin} \startcolumns \input knuth \stopcolumns \page[yes] \inouter{Text in Margin} \startcolumns \input knuth \stopcolumns \stoptext --- I hope someone can help me.

Standalone MetaPost Graphics from ConTeXt
by Troy Henderson 30 Aug '12

30 Aug '12

Is there a way to output several MetaPost PDF graphics from a single ConTeXt source file. For example, \startMPpage draw fullcircle scaled 72; \stopMPpage \startMPpage draw unitsquare scaled 72; \stopMPpage and have a separate output PDF generated for each MPpage? It seems that this ConTeXt code generates a single PDF which contains only the first graphic. I would like to have either 1) two separate PDF's with each containing their own graphic 2) a single two page PDF where each page corresponds to the appropriate graphic. Of course, the "holy grail" would be to be able to "compile" a MetaPost source file with ConTeXt. Troy Henderson

Vertical alignment in Natural tables
by Aditya Mahajan 27 Aug '12

27 Aug '12

Hi, How do I set the vertical alignment of cells in natural tables? I remember that \setupTABLE[align={middle,middle}] used to set center align vertically and horizontally. Currently, \setupTABLE[align={middle,high}] and \setupTABLE[align={middle,low}] work as expected, but \setupTABLE[align={middle,middle}] does not work. I also tried \setupTABLE[location={low}] (or lohi, or middle), but the calculation of height is wrong in those cases.

Numbering of figures and tables changed?
by Robert Blackstone 26 Aug '12

26 Aug '12

Dear list, In the book/thesis I am typesetting the many figures (Examples) and the few tables must be numbered per chapter, (Ex. 1.3, Ex. 4.17 etc) and they should appear like this in the List of Examples. Up to around 27 july this worked perfectly, automatically I should say, but with a newer version of mkiv (25 august) they come out numbered for the book as a whole and without chapter numbers. I have not changed the setups, and I can reproduce the correct result with an older version of mkiv (may) with a slightly adapted environment file. Unfortunately I do need some recent features of mkiv. The setups for the floats are: \definefloat[Example][examples] \setupfloat[Example][spacebefore=medium,spaceafter=medium,sidespacebefore=medium,sidespaceafter=medium] \setupcaption[Example][location=top,number=yes,inbetween=\blank,bodyfont=10pt] \setuplabeltext[en][Example=Ex.~] \definefloat[table][tables] \setupfloat[table][spacebefore=medium,spaceafter=medium,sidespacebefore=medium,sidespaceafter=medium] \setupcaption[table][location=top,number=yes,inbetween=\blank,bodyfont=10pt]\setuplabeltext[en][table=Table~] I tried [way=bychapter] as an argument for the captions but that did not change anything' What can I do to give me back the numbering of the floats per chapter? Or, if it is a bug in the recent Minimals, can the numbering per chapter be restored somehow? Thanks in advance. Best regards, Robert

Margin text and multiple columns
by Marc Rummel 23 Aug '12

23 Aug '12

Hello, I have a problem with margin texts in combination with multiple columns using mkiv. I want to set a text in the outer margin of a double sided document. This works well using \inouter as seen in the following document: --- \setuppagenumbering[alternative=doublesided] \starttext \inouter{Text in Margin} \input knuth \page[yes] \inouter{Text in Margin} \input knuth \stoptext --- But fails, when I use it in combination with multiple columns. Then the margin text of the odd pages is set in the second column (probably in the margin of the first column) instead of the margin of the whole page. --- \setuppagenumbering[alternative=doublesided] \starttext \inouter{Text in Margin} \startcolumns \input knuth \stopcolumns \page[yes] \inouter{Text in Margin} \startcolumns \input knuth \stopcolumns \stoptext --- I hope someone can help me. Best wishes, Marc

mp

Hi, In the next version you can run mp files: % test.mp beginfig(1) ; fill fullcircle scaled 10cm withcolor 0.5red ; fill fullcircle scaled 4cm withcolor 0.5white ; endfig ; beginfig(2) ; fill fullcircle scaled 10cm withcolor 0.5green ; fill fullcircle scaled 5cm withcolor 0.5white ; endfig ; beginfig(3) ; fill fullcircle scaled 10cm withcolor 0.5blue ; fill fullcircle scaled 6cm withcolor 0.5white ; endfig ; as follows: context test.mp and you'll get a pdf file with 3 pages that can be included with \externalfigure[test][page=1] \externalfigure[test][page=2] \externalfigure[test][page=3] or used in different ways. Alteratively you can run % test.tex \starttext \processMPfigurefile{figures-001.mp} \stoptext In which case you can add styling directives in the preamble.

Code in contextref-env.tex
by john Culleton 22 Aug '12

22 Aug '12

In the file contextref-env.tex I find code like the following: \setupsectionblock[\v!frontpart] [\c!page=\v!yes] \setupsectionblock[\v!bodypart] [\c!page=\v!yes] \setupsectionblock[\v!appendix] [\c!page=\v!yes] \setupsectionblock[\v!frontpart] [\c!before=,\c!after=] I have no idea what the sequences like "\v!"and "\c!" etc. mean.

Creating TeX dimensions and counters registers directly in Lua
by Jaroslav Hajtmar 22 Aug '12

22 Aug '12

Hello all, Is it possible to create a new dimension ConTeXt register directly in Lua, or I have to first create the ConTeXt dimensional register and then to subsequently assign it a value? Here is example: \starttext \newdimen\mydimension \directlua{tex.setdimen("mydimension", 123)} \stoptext works fine, but all like: \starttext \directlua{tex.print([[\newdimen\myotherdimension]])} \directlua{tex.setdimen("myotherdimension", 123)} \directlua{tex.newdimen("myotherdimension")} etc... \stoptext fails. In addition, I am interested in whether directly in Lua to create a new counter as in the previous. \starttext \newcount\mycount \directlua{ tex.setcount("mycount",125) } again works, but anything like: \starttext \directlua{tex.print([[\newcount\myothercount]])} \directlua{tex.newcount("myothercount")} etc... \stoptext again fails... Is there any source or examples to study anything about it? Thanx Jaroslav

Ctx ... Lua
by Procházka Lukáš 22 Aug '12

22 Aug '12

Hello, sometimes in this mail discussion I'm encountering a Ctx/Lua command which has been unknown for me or I would use other (known) commands to do the job. So - would it be possible to explain - what's the difference/advantage btw \directlua and \ctxlua - what \ctxcommand{} does - what \cldcontext{} does? TIA. Lukas

Lua: document v. userdata
by Rogers, Michael K 22 Aug '12

22 Aug '12

In a recent thread, Hans used the document namespace, where I (naively) expected userdata: On Aug 22, 2012, at 6:32 AM, Hans Hagen wrote: \ctxlua{document.myluadimension = "200pt"} Is there a reason not to use userdata.myluadimension? Or is document.myluadimension safe, because myluadimension is almost certainly not an entry used by ConTeXt? Is using document.myluadimension better "style" here, in some sense? Somewhere I had gotten the idea that if a ConTeXt user wanted to store something in Lua, they ought to store it in the userdata namespace.

Struggling with ConTeXt
by Olivier Binda 22 Aug '12

22 Aug '12

Hello I'm trying to port a big 300+ pages math course full of macros from plain XeTEX to ConTeXt mark IV (ubuntu 12.04+ stand alone beta) and I'm having some difficulties, could you please help ? My questions : 1) does lxml.att("#1","some tag") really work ? the next snipet doesn't work for me: \startluacode function set(node) p = lxml.att(node,"p") -- or p = lxml.att(lxml.id(node),"p") end \stopluacode \startxmlsetups xml:section \ctxlua{set("#1")} \stopxmlsetups it looks like it returns the p attribute of the node before #1 the following snipet works though (which is strange because I looked in the context source and it gives \def\xmlatt#1#2{\ctxlua{lxml.att("#1","#2")}}...) \startxmlsetups xml:section \ctxlua{p = \xmlatt{"#1","p"}} \stopxmlsetups 2) I'm trying to export to xml and have set \setupbackend[export=yes, xhtml=yes, css=mkiv-export.css] But a) my Metafun/Tikz pictures aren't exported to svg :/ b) the exported xml has namespaces problems (like error on line 63 at column 20: Namespace prefix m on math is not defined error on line 64 at column 22: Namespace prefix m on mrow is not defined) What am I doing wrong ? (I'm compiling with "context mydoc.tex") Is there some \csname tex4ht\endcsname command or some other directive that I should use to get my xml export right ? Am I missing some namespace commands (there are lots of m:math and m:mrow mathml tags int the exported xml source, this smells like a tex4ht issue) 3) I have defined some framed text with metafun overlays (like in the Context manual) and I'm trying to type something like \inmargin{some label} \startMyFramedText...\stopMyFramedText Yet, the text in the margin is after the framed text :( (fiddling with the "location" setting (low, ..) doesn't allow me to have the in margin text right next the top of the framed text I somehow found a dirty workaround with typing a blank space \defineframedtext[Property][frame=off,background=OverlayProperty,before={}] and \inmargin{some label}\noindent\startMyFramedText...\stopMyFramedText but it's not really satisfying. (hate to lose vertical space with wandering blank spaces) Is there a better way ? 4) I'm trying to port the following TeX code to ConTeXt $$\eqalign{x&=1\cr y&=2\cr}\qquad \hbox{haha}$$ it looks like \startformula\startalign.. doesn't allow me to do that I somehow managed to have it by typing \startformula \vcenter{\starttabular[|rM|lM|] \NC x \NC =1\NC\NR \NC y \NC =2\NC\NR \stoptabular}\qquad\text{haha} \stopformula the pdf export is fine, but the xml export is awfull (because of \vcenter I guess) a) Is there a way to use tables inside math mode alongside other stuff (would be handy) ? b) what is the correct way to type the previous text, so the pdf and xml are fine in Context ? Best regards Olivier... really enjoying utf, xml, lua inside TeX as well as other nice ConTeXt features

subformulas: error in latest beta
by Andreas Mang 21 Aug '12

Dear all, I am having problems with subformulas. The following example does not display a subnumber (i.e. I get (1) and (2) instead of (1a) and (1b)): %%%%%%%%%%%%% start example %%%%%%%%%%%% \starttext % from % does not display "subformula numbers"" \placesubformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+][a] \NC a_2 x + b_2 y \NC = c_2 \NR[+][b] \stopalign \stopformula %%%%%%%%%%%%% stop example %%%%%%%%%%%%% This example is taken from http://dl.contextgarden.net/myway/mathalign.pdf page 6 I am not quite sure for how long this is not working. I have been using the following alternative, which used to work but now gives me an error with the latest beta (ConTeXt ver: 2012.08.16 22:20 MKIV fmt: 2012.8.18): %%%%%%%%%%%%% start example %%%%%%%%%%%% % the following used to work in an earlier version \startsubformulas[eq:ax=b] \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+][a] \NC a_2 x + b_2 y \NC = c_2 \NR[+][b] \stopalign \stopformula \stoptext %%%%%%%%%%%%% stop example %%%%%%%%%%%%% Any suggestions?
