Clipping multiple PDFs
by jethro Reuel 23 Aug '22

23 Aug '22

Hello, I am trying to put multiple PDF’s that were typeset differently into one document without modifying the individual files themselves. I came up with this: \starttext \copypages[ass1.pdf][][scale=950] \copypages[ass2.pdf][][scale=950] … stoptext The problem is the original page numbers show and I’d prefer that it did not. So I thought maybe I could clip all the page numbers from every page (since they are all in the same position across all the pages) but I don’t know how to do this with the \clip command. Any ideas? I already tried using \input but it gives some weird output in some places. It doesn’t have to use this method as long as it does what I need it to do. Thanks in advance. Jethro

Thanks for the solution Pablo. It works well. I wanted to add more pdfs (which also has many pages) and found it was easier for me to reason in the lua side of things. This is what I have at the moment: \starttext \startluacode local function doc(fil) return fil..[[.pdf]] end local function disppdf(fname) n = 1 repeat context.externalfigure({fname},{ page = n, width = "200mm", scale = "950" }) n = n + 1 until n == context(context.noffigurepages) end local pdffiles = {"ass1", "ass2", "ass3", "ass4", "ass5", "ass6", "ass7", "ass8"} for index=1,#pdffiles do local f = doc(pdffiles[index]) context.getfiguredimensions({f}) disppdf(pdffiles[index]) end \stopluacode \stoptext I didn’t know how to get an array (or indexed table or whatever you call it) in ConTeXt/Tex. My problem is now with context(context.noffigurepages). It doesn’t produce an integer so n is being compared to nil. Am I calling it wrong? All I want to do is call \noffigurepages from the lua side. Is there something I am missing?

How to reset settings in setuphead back to defaults?
by Joel 21 Aug '22

21 Aug '22

I have some settings like this, which define the part, chapter, and section titles within a file that contains all of my common settings for all files. \definepagebreak[chapterpagebreak][yes, right] \setuphead[part][style=\sse, placehead=yes, expansion=yes] \setuphead[chapter][style=\sse, placehead=yes, expansion=yes, page=yes, numbercommand=\groupedcommand{}{\blank[1cm]}, alternative=middle, numberstyle=ssl, numbercolor=white, strut=yes, page=chapterpagebreak, header=empty] \setuphead[subject][style=\sse, placehead=yes, expansion=yes, page=yes, numbercommand=\groupedcommand{}{\blank[1cm]}, alternative=middle, numberstyle=ssl, numbercolor=white, strut=yes, page=chapterpagebreak, header=empty] A problem I have is I need one document to ignore all the above, basically pretend each of these is reset to defaults. Is there a way to rest all of the above items to default settings quickly? --Joel

ConTeXt Workshop at FrOSCon
by juh 21 Aug '22

21 Aug '22

Dear all, my workshop is over and it was quite nice. There were five people that attended the whole workshop and two that looked into it and left after some minutes. I had their attention from the beginning, after I showed them the flyers I made for my cooperative. https://www.hasecke.eu/post/werbemittel-mit-context-gestalten/ I guess that this is what people expect from ConTeXt: individually styled products. The workshop was two hours long so that I could only show the very first steps. One interesting thing is that one person never worked with TeX or LaTeX before. The others had experience with LaTeX of course. Is this an indication that ConTeXt can attract people that never worked with TeX before? There is one thing that is quite error prone for beginners, a small detail during the installation process. Everyone worked on Linux and was able to use the command line but nonetheless two of five had problems to correctly set the PATH variable. So I have one question. Is it possible or reasonable to extend the install script so that it adds the new path directly to .bashrc? Or at least to ask the user if the script should do this? Now we have to do theses steps: sh .install.sh copy the line with the path vim .bashrc insert the line, save and exit vim source .bashrc I can think of arguments against the idea of an installation script that set the variable automatically. One thing is that not everyone uses bash, many use zsh. As I use both shells I set many environment variables in a custom file called .exportrc. So for me personally the extension of the script would be of no advantage. But maybe it can ease the way of beginners. Thanks a lot to Hraban and to Joaquín. The "introduction" and Hrabans manuscript helped me to outline the things I wanted to show. juh -- Autoren-Homepage: ......... http://literatur.hasecke.com Satiren & Essays: ......... http://www.sudelbuch.de Privater Blog: ............ http://www.hasecke.eu Netzliteratur-Projekt: .... http://www.generationenprojekt.de

Repeating binary operators with split multiline formulas
by Adam Reviczky 21 Aug '22

21 Aug '22

Hi, Since there has been a lot of work done on the math side of things, I wanted to ask if there is an automated way to have binary operators repeated when splitting a formula. From the MKIV math manual there is an option to move the operators into the new line: \setupmathematics[setups=math:spacing:split] \setupformulas[split=yes,align=flushleft] \startformula x\dorecurse{30}{ + #1x^{#1x}} = 10 \stopformula Would it be possible to achieve this via a custom setup like math:spacing:split to get an output like this? 𝑥 + 1𝑥1𝑥 + 2𝑥2𝑥 + 3𝑥3𝑥 + 4𝑥4𝑥 + 5𝑥5𝑥 + 6𝑥6𝑥 + 7𝑥7𝑥 + 8𝑥8𝑥 + 9𝑥9𝑥 + 10𝑥10𝑥 + + 11𝑥11𝑥 + 12𝑥12𝑥 + 13𝑥13𝑥 + 14𝑥14𝑥 + 15𝑥15𝑥 + 16𝑥16𝑥 + 17𝑥17𝑥 + 18𝑥18𝑥 + 19𝑥19𝑥 + + 20𝑥20𝑥 + 21𝑥21𝑥 + 22𝑥22𝑥 + 23𝑥23𝑥 + 24𝑥24𝑥 + 25𝑥25𝑥 + 26𝑥26𝑥 + 27𝑥27𝑥 + 28𝑥28𝑥 + + 29𝑥29𝑥 + 30𝑥30𝑥 = 10 Adam

A few questions about texmfcnf.lua and mtxrun in TexLive.
by amano.kenji 20 Aug '22

20 Aug '22

I'm currently using TexLive 2021 from Gentoo Linux. TexLive 2022 may behave with slight differences. * How does /usr/share/texmf-local/web2c/texmfcnf.lua override /usr/share/texmf-dist/web2c/texmfcnf.lua? According to mtxrun --configurations, /usr/share/texmf-dist comes later than /usr/share/texmf-local. It seems to me that texmf-dist should override texmf-local. * mtxrun --resolve-path '$SELFAUTOPARENT' resolves selfautoparent to '.' which is the current working directory if selfautodir is /usr. I think mtxrun refuses to accept '/' as selfautoparent and assigns the current working directory to selfautoparent. Is this a bug?

Color property of \setupurl
by Joaquín Ataz López 20 Aug '22

20 Aug '22

Good morning everyone. I have been doing some tests on the "color" property of \setupinteraction and the "color" property of \setupurl and my feeling is that the color of the hyperlinks is always controlled by \setupinteraction. Could someone clarify me in what kind of context the color of a hyperlink is controlled by the "color" property of \setupurl? -- Joaquín Ataz López Derecho civil Universidad de Murcia | jal(a)um.es
