professional looking tables
by Csikos Bela 30 Dec '16

30 Dec '16

Dear context users: In latex I could make professional looking tables using booktabs module. Using longtable package I could make nice looking multipage tables. I see that context offers several table environments. Which one of them is suitable for making professional (publication quality) tables? The requirements for such tables are the follows: - Only horizontal rules are needed - Ability to set the rule's thickness for top rule, bottom rule, middle rule - Ability to set the distance between rules and table content - Ability to set rule length shorter than cell or row width on both left and right sides - Ability to set rules for spanning only some of the columns In addition, for multipage tables: - head row at the start of table - head rows at top on every page (possibly including first page) - foot row ate the end of table - foot rows at the end of every page (possibly including last page) Is this feasible in current context? Thank you in advance, bcsikos

columnsetspan extra line
by Mikael P. Sundqvist 29 Dec '16

29 Dec '16

Dear all, I'm struggling with the column environments these days. The code below runs fine, but there are some problems with the result. 1) There is an extra blank line at the top of the left column. I can get rid of it with a \vskip-\baselineksip (commented out in the example) but that feels like a hack. Does anyone see why it is there from the beginning? 2) Why is the frame something like 3 lines down from the top of the page? Can I force it to be on top? 3) Is there a simple way to define the height of the frame (that is now set to 0.3\textheight) to be a certain number of lines? %%% Start of example \usemodule[newcolumnsets] \setuplayout[ grid=yes, ] \showgrid \definecolumnset[example][n=2] \definecolumnsetspan[intro][n=2,after=,before=,] \define[1]\mychapnum{% \startuseMPgraphic{chapnum} label(btex {\bf #1} etex scaled 12, (0.5*OverlayWidth,0.5*OverlayHeight)) withcolor darkred; setbounds currentpicture to unitsquare xyscaled (OverlayWidth,OverlayHeight); \stopuseMPgraphic } \defineoverlay[chapnum][\useMPgraphic{chapnum}] \define[1]\mychaptext{% \startcolumnsetspan[intro] \startframedtext[align={middle,lohi},background=chapnum,frame=on,framecolor=darkyellow,rulethickness=2pt,width=\makeupwidth,height=0.3\textheight,after=,before=] \setupinterlinespace[line=60pt] #1 \stopframedtext \stopcolumnsetspan } \setuphead[chapter][ style={\definedfont[Serif at 48pt]}, numbercommand=\mychapnum, textcommand=\mychaptext, after=, before=, page=no, ] \starttext \startcolumnset[example] \chapter{A chapter} %\vskip-\baselineskip \dorecurse{2}{\input knuth \par} \stopcolumnset \stoptext %%% end of example

Hello, The integral symbol is little in inline math mode. Is it possible to have it bigger ? thank you, Fabrice \definetypeface [mainface] [rm] [serif] [palatino] [default] [encoding=texnansi] \definetypeface [mainface] [ss] [sans] [helvetica] [default] [encoding=texnansi] \definetypeface [mainface] [tt] [mono] [palatino] [default] [encoding=texnansi] \definetypeface [mainface] [mm] [math] [palatino] [default] [encoding=texnansi] \setupbodyfont[mainface,11pt] \starttext L'aire hachurée se note \math{\int_1^3 k(x)\mathop{dx}}.

Strange numbers appear (when figures are moved in columnsets)
by Mikael P. Sundqvist 28 Dec '16

28 Dec '16

Hi! The example below gives strange numbers (4110) and (1410) in the pdf file, and the latter one kicks me out of the grid. Is this a bug? /Mikael (yes, I'm using a late standalone) %% start of example \setuplayout[ grid=yes, ] \showgrid \definecolumnset[example][n=2] \starttext \startcolumnset[example] \dorecurse{2}{\input knuth \par} \placefigure[btlr]{Caption}{\blackrule[width=\textwidth,height=4cm]} \input knuth \stopcolumnset \stoptext %% end of example

new xml feature (for html lovers)
by Hans Hagen 28 Dec '16

28 Dec '16

Hi, As a side effect of a fun project I've added css like selectors to the xml interface, so one can do: \xmlall{#1}{{foo bar .whatever, bar foo .whatever}} \starttext \startbuffer[selector-003] <?xml version="1.0" ?> <document> <title class="one">title 1</title> <subtitle class="sub">title 1.1</subtitle> <title class="two">title 2</title> <subtitle class="sub">title 2.1</subtitle> <title class="one">title 3</title> <subtitle class="sub">title 3.1</subtitle> <title class="two">title 4</title> <subtitle class="sub">title 4.1</subtitle> </document> \stopbuffer \xmlloadbuffer{selector-003}{selector-003} \startxmlsetups xml:selector:demo \xmlverbatim{#1}\par \stopxmlsetups \xmlcommand {selector-003} {{document title .one + subtitle, document title .two + subtitle}} {xml:selector:demo} \stoptext Performance should be ok although (currently) a combined selector triggers a result sorter which has a small speed penalty. After all you don't want your document to come out in the wrong order. like things. In the process I optimized an aspect of the parser and hopefully I didn't break anything.

Re: [NTG-context] floatcombination alignment has changed?
by Christoph Reller 28 Dec '16

28 Dec '16

Dear List, Consider the following MWE: \startplacefigure \startfloatcombination \startplacetable[title={Table I}] % <- shifted %\startplacetable % <- not shifted \bTABLE \bTR \bTD Foo \eTD \bTD Text. \eTD \eTR \eTABLE \stopplacetable \startplacetable[title={Table II}] % <- shifted %\startplacetable % <- not shifted \bTABLE \bTR \bTD Foo \eTD \bTD Text. \eTD \eTR \eTABLE \stopplacetable \stopfloatcombination \stopplacefigure The resulting output looks strange to me. The tables are shifted to the left when compared with omitting the titles. In earlier versions of ConTeXt, no such shift happens. Do floatcombinations not work? Any feedback is welcome. Cheers, Christoph

Back on grid after displayed math
by Mikael P. Sundqvist 26 Dec '16

26 Dec '16

Hi! Im curious how to get back to the grid after a displayed formula? I try \setuplayout[grid=yes] \showgrid \setupformulas[align=middle] \starttext \input knuth \startformula a^2+b^2=c^2 \stopformula \input knuth \stoptext (where the \setupformulas[align=middle] was suggested in a comment at http://tex.stackexchange.com/questions/254815/grid-on-aligned-equations-in-… , but that makes no difference) but that does not work (result attached). Would it be easier if there were also an option saying how many lines the equation should take? Say, \startformula[lines=3] a^2+b^2=c^2 \stopformula and then centering the formula (or having options for that) vertically over the three lines? Maybe that is a not a good idea for some reason... /Mikael

"\" in text from "\comment"

Dear Hans, I’m afraid I might have hit a bug (with beta from 2016.12.21 18:51): \startbuffer[demo] <doc> <p>pandoc</p> <pre><code>\ConTeXt\ is great</code></pre> </doc> \stopbuffer \startxmlsetups xml:initialize %~ \xmlsetsetup{#1}{doc|p|pre|code}{xml:*} \xmlsetsetup{#1}{doc|p|code}{xml:*} \xmlsetsetup{#1}{pre/code}{xml:pre:code} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:pre:code \comment[symbol=Key, location=inmargin, color=yellow]{\xmlflush{#1}}\xmlprettyprint{#1}{tex} \stopxmlsetups \setuppapersize[A6] \setupinteraction[state=start] \starttext \xmlprocessbuffer{main}{demo}{} \stoptext Text from comment reads "\Ux {5C}ConTeXt\Ux {5C} is great". It should read "\ConTeXt\ is great". Am I missing something or is this a real bug? Many thanks for your help, Pablo -- http://www.ousia.tk

\copypages and page numbering
by Andrea Valle 22 Dec '16

22 Dec '16

Dear all, I’m assembling into a unique pdf the proceedings of a conference. They have been created by various sw (latex, word, writer etc). In order to include the papers, I’m just using a series of commands like \copypages[CIMXXI_contributi/dapelo][][scale=950] They are not provided with page numbers, and I’m including them in the usual way. Now, most of the time it just works. All the papers should conform to a template, but in some cases, page numbers are not displayed, and this depends on the fact that the page setup in that paper has a greater height (or maybe a different crop area), so that it covers the page number. I would simply solve the problem by having the page number on top of the imported pdf. Is it possible?
