LMTX and addplot table
by Jean-Philippe Rey 12 Dec '20

12 Dec '20

Dear list, I am unable to draw a plot using an external file with LMTX. Here is a minimal example ===================== \usemodule[pgfplots] \starttext \starttikzpicture \startaxis \addplot table [x=t, y=E] {mfe-addplot.dat}; \stopaxis \stoptikzpicture \stoptext ===================== The ConTeXt run fails with an "Undefined control sequence" error (see attached log file). I don't know if this is an LMTX or PGF issue. The example works fine with MkIV. I tried with the tikz version available on ConTeXt garden (pgf 3.0.1, pgfplots 1.16) and the last one from CTAN (pgf 3.1.7a, pgfplots 1.17) with the same result. The same example works fine if I provide the data inline. This looks like a problem while reading the data file. Thanks for your insight.

issue with link and margin in LMTX
by Pablo Rodriguez 12 Dec '20

12 Dec '20

Dear list, I have the following sample: \setuppapersize[A9] \setupinteraction[state=start] \enabledirectives[references.border] \unexpanded\def\MyURL#1% {\bgroup\goto{{\tt\hyphenatedurl{#1}}}[url(#1)]\egroup} \starttext \startitemize \dorecurse{2}{\item \MyURL{a.b\\/c.d\letterhash e}} \stopitemize \stoptext I’m afraid that the link has problems with margin in MkXL (MkIV doesn’t have any problems with it). Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

checkbox in fields show the word yes
by Jan U. Hasecke 11 Dec '20

11 Dec '20

Hi all, with this example I get a checkbox that does not work; in my real world document it works, I can't say why. But this minimal example shows the problem I have in my real document. \usemodule[fields] \setupinteraction [state=start] \setupfield[cbox][width=1em,height=1em,option=printable,frame=on,offset=0.5mm,frameoffset=1mm,type=radio,color=black] \definefield[test][check][cbox][yes][no] \starttext \field[test] \space Do you see the word »yes«? \stoptext Unfortunately in Firefox and some other PDF Viewer there is the word "yes" written in the checkbox. This makes the form useless as people think the given option is set to yes by default. Can I avoid this somehow? TIA juh

Unnecessary page break, leaving lines empty
by Huseyin Özoguz 11 Dec '20

11 Dec '20

Hello, I have an unnecessary pagebreak in the following min-example: the last four lines of the first page are left empty, without obvious reason: \setupinterlinespace[line=3.0ex] \setupbodyfont[10pt] \showgrid \setuplayout [location=middle, topspace=17mm, header=0mm, footer=12mm, bottomspace=15mm, width=middle, cutspace=20mm, backspace=19mm, grid=yes ] \showgrid \starttext \chapter{Überschrift} \dorecurse{260}{hallo wie geht es? } \section{Überschrift}Text. \stoptext The problem seems to be the combination of the layout, bodyfontsize and interlinespace. If I change any of them, even by a small number, the problem vanishes. Whats the underlying problem and how to solve it without changing layout, fontsize or interlinespace? Thanks.

Metafun: is it possible to redefine dotlabel to draw a square ?
by Otared Kavian 10 Dec '20

10 Dec '20

Hi all, In Metafun when representing a point I woul dlike to have some dots represented by a square (or even by another scalable symbol): for instance in the following I would like the dot at the point B to be a square: \starttext \startMPcode draw (2cm,3cm) -- (3cm,5cm) ; dotlabel(textext("\switchtobodyfont[8pt]" & "A"), (2cm,3cm)) withpen pencircle scaled 12pt withcolor transparent("exclusion",.5,red) ; dotlabel(textext("\switchtobodyfont[8pt]" & "B"), (3cm,5cm)) withpen pencircle scaled 12pt withcolor transparent("exclusion",.5,red) ; \stopMPcode \stoptext I wonder whether it is possible to define something like « drawsquaredot » or « squaredotlabel » in order to do this. If I use for B the command withpen pensquare scaled 12pt then the dot is a square, but the label B is drawn in a strange way. Thanks for any help: Otared

LMTX, repeated caption
by Jean-Philippe Rey 10 Dec '20

10 Dec '20

Dear list, In some unclear circumstances, a figure caption is repeated above the figure, as with the following example. ====================== \starttext \placefigure {This caption shouldn't be repeated} {\hbox{anything here}} \stoptext ====================== The caption is not repeated for all figures. With a longer caption or a wider figure, the bug disappears. My guess is that it is triggered by a certain ratio between caption length and figure width! I hope this helps.

Metafun: how to draw a straight line past the end points
by Otared Kavian 09 Dec '20

09 Dec '20

Hi, I have a silly question: given two points in the plane z1 = (1cm,3cm) ; z2 = (5cm, 9cm) ; the command draw z1 -- z2 withpen pencircle scaled .5pt ; draws the line segment joining z1 and z2. How could I draw the line segment which goes a little further (say 1cm) than both the end points of this segment (that is in this example, a point before z1 and a point after z2 on the straight line) . Indeed it is possible to write the equation of the line and then compute by hand the coordinates of the new end points, but I think there is a simpler way in Metafun to do this. Thanks for any help: Otared

Automatically setting the value of list key in annotation module
by Aditya Mahajan 09 Dec '20

09 Dec '20

Hi, In the annotation module, is it possible to automatically set the value of the `list` key to be the same as the value of `title` key (as is the case with \startsection, for example). Here is a non-working example: \usemodule[annotation] \defineannotation[test][alternative=paragraph] \starttext \placelist[test][criterium=all] \starttest[title={This is a title}] \input ward \stoptest \starttest[title={This is another title}, list={This is in the 2nd list}] \input ward \stoptest I want the first title to also be added to the list. Thanks, Aditya

image align in \clip
by Jan U. Hasecke 09 Dec '20

09 Dec '20

Dear all, I use \clip to simplify working with images. I have a problem that I am unable to reproduce in a MWE. \setupexternalfigure[location=default] \showframe \starttext \externalfigure[cow.pdf][width=\textwidth] \clip[height=50mm] {\externalfigure[cow.pdf][width=\textwidth]} \stoptext In my real document the clipped image is shifted to the right as if indented by 1em or so. Any hints where to look for the reason? TIA juh

Quirk with \userpagenumber, datasets and the .tuc file
by Bruce Horrocks 09 Dec '20

09 Dec '20

Here's an odd quirk... I wanted to get at some of my dataset data for use outside of ConTeXt so I thought I would just extract it from the .tuc file. MWE: \definedataset [MyDS][delay=yes] \starttext \input tufte \setdataset [MyDS] [ title={Test title}, page={\userpagenumber}, ] \stoptext In the TUC file I get: utilitydata.job.datasets.collected={ ["MyDS"]={ { ["index"]=1, ["order"]=1, ["page"]="1\\relax ", ["realpage"]=1, ["title"]="Test title", }, }, } Note the \\relax following the page number. This isn't a problem for me at the moment but I wondered if it is something that needs to be looked at? -- Bruce Horrocks Hampshire, UK
