issue with \comment
by Pablo Rodriguez 16 Jun '20

16 Jun '20

Dear list, when trying to report another issue, I found the following one (using latest from 2020.06.12 17:43): \setupinteraction[state=start] \starttext a\contextversion \comment[location={rightmargin}]{comment} \stoptext For some strange reason, \comment isn’t added when there is no other content in the paragraph. I think it might be a bug. Could anyone confirm this? Many thanks for your help, Pablo -- http://www.ousia.tk

Filter module for R
by Fabrice L 15 Jun '20

15 Jun '20

Hi, Following a question about the broken R module (R the statistical software), Aditya suggested me the filter module (thanks to him). I’m about to distribute a set of course notes to colleagues, and I need to deal with details now. I have one problem and two questions. 1) the filter collect R code between \startR / \stopR and submit this code to R. As it can be seen in the following minimal example, when a label contains an accented character (« Fréquence » in my example), the pdf graphic does not contains the « é ». Strangely, the snippet of code (which is saved locally as « test2-temp-R-0.tmp » (for test2.tex)) when submitted with the same command as the filtercommand, works correctly; that means the same file works when submitted to R outside of ConTeXt. I have no idea how to solve this. 2) In a teaching context, we may want sometimes to show the code. The filter module actually permits to show the output of the code submitted to R (which can include or not the input commands); would it be possible to typeset the submitted code ? 3) Finally, using "R CMD BATCH… » as the filtercommand add an extra line at the end of the output file which can be typeset to visualize results. Would it be possible by a magic trick to deleter the last line of the file ? Here is a minimal code: % ————————————————— \usemodule[filter] \defineexternalfilter [R] [ filtercommand={R CMD BATCH -q --no-timing --save --restore \externalfilterinputfile\space \externalfilteroutputfile}, output=\externalfilterbasefile.out, directory=output, readcommand=\typefile, read=no, cache=yes, purge=yes ] \starttext Some text... \startR[read=yes] pdf("RPlots/MyHistogram.pdf",5,5) X <- rnorm(200,mean=10,sd=2) hist(X, col = "red3" , xlab="Score QI" , main="", ylab="fréquence") \stopR \externalfigure[MyHistogram.pdf][width=.5\textwidth] \stoptext % ————————————————— Sorry for the three questions… and thanks for any help. Fabrice.

issue with remote \attachment
by Pablo Rodriguez 15 Jun '20

15 Jun '20

Hi Hans, one of my documents uses \attachment to embed PDF documents (well, it contains many). I have been doing this for more than a year, but right now it is way slower: over 250s vs. 7s compilation time (with and without the attachment). It takes me 6s to download the document directly with curl using the same address. I’m afraid this might be also related to the server where the file is downloaded from. The document seems to be downloaded in each run. I wonder whether this could be improved with these proposals: 1. Only download the document on the first run of each compilation. 2. Before that, check last modified information (from "curl -I") and avoid downloading if the already downloaded file is newer that the remote version. 3. It would be better if downloaded files could have the remote time ("curl -R"), instead download time. CreationDate and ModDate might differ from upload time. A sample for that would be https://etsc.eu/wp-content/uploads/2014_06_smart_factsheet_alco_gate_sweden…. These are dates from the PDF document: CreationDate: Mon Jul 7 14:57:05 2014 CEST ModDate: Mon Jul 7 14:57:07 2014 CEST And this is what "curl -I" displays about uploading time: Last-Modified: Sat, 24 Mar 2018 13:51:29 GMT Would it be possible to implement these proposals to improve remote file embedding? Many thanks for your help, Pablo -- http://www.ousia.tk

Bar within math (amended)
by Lukas/ConTeXt 15 Jun '20

15 Jun '20

Hello, it seems that bar (even with option 'continue=yes') is not rendered in place of '~' within math. See the sample: ---- \definebar[MyBar][color=green,rulethickness=2.8,order=background,offset=1.5,continue=yes] \starttext 1 + 2 = \startbar[MyBar]3~kN\stopbar % OK $1 + 2 = \startbar[MyBar]3~\text{kN}\stopbar$ % No background behind space $1 + 2 = \inframed[frame=off,background=color,backgroundcolor=green,offset=0pt,]{3~\text{kN}}$ % OK! \stoptext ---- In the sample 'kN' is a unit, which should be separated by space from the result (here: 3); I am used to put the unit into the math environment and enclose it into \text{...}. Is there a way to make the bar be rendered in places of blanks within math, too (like if it was inside $ ... $ - as the first line of the sample)? - Note that I can use \inframed to get background filled fully, but anyway - how about usage of "bar" for this? Best regards, Lukas

start/stop executed conditionally on mode ?
by Fabrice L 15 Jun '20

15 Jun '20

Dear List, I would like to insert a page using (ideally) start/stop instructions. The problem is that this page should be inserted only in a certain mode. Consulting the mailing list, I thought the following code was working, but it’s not ! The code is executed in the mode as expected, but the following instructions ("Some other text... » in the exemple) is not typeset. Here is a minimal (not working!) example: % ———————————————————————————————————— \unexpanded\def\StartQuestionsList{ \startmode[ClassRoom] \page[yes] Here are some questions: \blank } \unexpanded\def\StopQuestionsList{ \page[yes] \stopmode } \definestartstop[Questions][ before=\StartQuestionsList, after=\StopQuestionsList ] \startQuestions Question A…. Question B…. \stopQuestions Some other text... % ———————————————————————————————————— So to be clear, I would like the result in the « ClassRoom » mode to be: % ———————————————————————————————————— Here are some questions: Question A…. Question B…. Some other text... % ———————————————————————————————————— Otherwise to be: % ———————————————————————————————————— Some other text... % ———————————————————————————————————— Thanks for any help ! Fabrice.

\recursestring undefined when inside \dorecurse
by Pablo Rodriguez 15 Jun '20

15 Jun '20

Dear list, I have the following sample: \starttext \dorecurse{25}{\recurselevel\par} \doloopoverstring{a,b,c}{\recursestring} } \stoptext Both LMTX and MkIV complain about \recursestring for being undefined. I wonder whether this is inteded or it is a bug. Many thanks for your help, Pablo -- http://www.ousia.tk

using annotations for extended print handling
by Pablo Rodriguez 14 Jun '20

14 Jun '20

Dear list, I have an over a thousand pages document generated with ConTeXt. I need to print and chapters and part of chapters (or send to other people). /PrintPageRange is great (and you can even generate a new document containing only the pages in /PrintPageRange). But the issue here is that I would need to recompile the document again for each new required /PrintPageRange. Another approach would be to add PDF annotations (outside page boundaries) to store the desired information. So I created text annotations (using \comment) with author information composed from unit number (such as "i3", "ii9" or "iii28"), info on the unit part (such as "-explanation", "-synopsis", "-exercises", or others) and position ("-start" and "-stop"). This would make author fields such as "i3-start" (which has a corresponding "i3-stop", or "ii22-synopsis-start" (with the corresponding closing annotation). To make easier to identify these annotations, they all share the same title. As contents, all these text annotations have the page number. From the generated PDF document, I need to read all text annotations in order to extract two fields from those annotations that contain a "whatever" /Subj. These fields are /T and /Contents. I guess that the way to deal with the (over 700) annotations would be to store both fields in a Lua table. But this is only a suspicion, since I don’t know how to read the values, how to store them, or how to compare them with specific units or unit parts to get these page numbers. I mean, with a command such as \extractpages{i5,i8-exercises,i15-explanation} would get the pages for each "-start" and "-stop" that could be passed automatically to a \filterpages command. A sample that generates something similar: \setuppapersize[A8] \setupinteraction[state=start] \starttext \dorecurse{5}{\part{\romannumerals{\recurselevel}} \dorecurse{15}{\chapter{\recurselevel} \comment [title=whatever, color=yellow, %~ the following code is to have expansion in interaction author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].."-start")}}] {\pagenumber} \doloopoverlist{explanation,exercises,synopsis}{\chapter{\recurselevel} %~ I would like to use \recursestring, but it is undefined here \comment [title=whatever, color=green, author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].. [[-\recurselevel]].."-start")}}] {\pagenumber} \dorecurse{5}{\null\page} \comment [title=whatever, color=blue, author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].. [[-\recurselevel]].."-stop")}}] {\pagenumber} } \comment [title=whatever, color=red, author={\ctxlua{context([[\namedstructurevariable{part}{title}% \namedstructurevariable{chapter}{title}]].."-stop")}}] {\pagenumber} } } \stoptext Is there a way to deal with the annotations in the document generated from the code above, in the way I described before? Many thanks for your help, Pablo -- http://www.ousia.tk
