Using command line values in a TeX document; writing a script?
by Gerben Wierda 15 Apr '20

15 Apr '20

Currently, I process a file like this: mtxrun --autogenerate --script context test12.tex and in the file test12.tex one sees something like this: \input archimate-mp \ctxlua{moduledata.archimate(“myarchimatefile.xml")} The latter parses the xml file and produces a PDF using generated MP code. What I would like to do is not have to edit the .tex file when I want to process another .xml file but just pass the name of the xml file on the command line. And I would like to pass on a second filename with some local overrides settings fr my code. All of this needs to be data that I can use in my programming. E.g. something like: mtxrun --autogenerate --script myscriptname “ myarchimatefile.xml” “myhelper.xml" It is OK that this would produce a fixed name output file (e.g. myparsedxml.pdf), so it is OK to have some generic myparsedxml.tex (instead of test12.tex as per my example) file that produces a .pdf and more in the current working directory but resides somewhere in a generic place. But preferably, this would produce myarchimatefile.pdf I’ve read the manual on mtxrun scripts to see if I can make my own, but I’m utterly failing to understand what is written in a way that let me write my own.

fun with frames and tables
by Henning Hraban Ramm 13 Apr '20

13 Apr '20

Hi, after I re-setup my computer (harddisk got tired...) I’m now trying to update my old Midgard RPG character sheet (https://github.com/fiee/ConTeXt/tree/master/midgard) and run into some problems that I don’t understand while trying to fill one page with several tables. Here’s a quite minimal example: \setupTABLE[c][each][width=2cm] \starttext \framed[offset=overlay,width=\textwidth]{% \vbox{\bTABLE \dorecurse{10}{\bTR\bTD x \eTD\bTD y \eTD\eTR} \eTABLE}% \hskip1cm% \vbox{\bTABLE \dorecurse{10}{\bTR\bTD x \eTD\bTD y \eTD\bTD z \eTD\eTR} \eTABLE}% } \stoptext I’m trying to get those tables side by side, but the size of the wrapping box is somehow miscalculated – if I set the width, the left table disappeares to the left, if I don’t, the box exceeds the paper width. Maybe it’s completely unrelated to the tables. In the full document, there’s also space before or after one of the tables, so that they don’t align. There are actually not just two tables, but a short wide one and a combination of 3*2 small ones on the left side (that’s why I seem to need that \vbox) and a big table on the right side. But I’ll care about the other problems if I understand what’s going on with those boxes. Happy Easter & best regards, Hraban

offset for background overlay
by mf 13 Apr '20

13 Apr '20

Hello list, this MWE is a simplified version of a real case: \startuseMPgraphic{cell:triangle} path p ; p := unittriangle rotated 90 xscaled 2.5 OverlayWidth yscaled 2.5 OverlayHeight ; draw p withcolor red ; \stopuseMPgraphic \defineoverlay[triangle][{\uniqueMPgraphic{cell:triangle}}] \starttext \bTABLE[frame=off] \bTR \bTD[nx=2,background=triangle,align=middle] \dontleavehmode a\crlf text \eTD \eTR \bTR[toffset=1mm] \bTD left \eTD \bTD right \eTD \eTR \eTABLE \stoptext The triangle is used as background of the 2-column wide cell of the first row. I want the triangle to go around the second row too, as if it were a frame for all the 3 cells. It means that it should be shifted down a bit. So I tried this: \startuseMPgraphic{cell:triangle} path p ; p := unittriangle rotated 90 xscaled 2.5 OverlayWidth yscaled 2.5 OverlayHeight ; draw p shifted (0,-3mm) withcolor red ; \stopuseMPgraphic ... but it does not work, because the content of the background is centered on the cell, so "shifted (0,-3mm)" has no effect. The only solution I found is drawing something above the triangle with a neutral color, so that the whole background is centered in the cell and the red triangle goes down: \startuseMPgraphic{cell:triangle} path p ; p := unittriangle rotated 90 xscaled 2.5 OverlayWidth yscaled 2.5 OverlayHeight ; fill p shifted (0,6mm) withcolor white ; % only to move the next one down draw p withcolor red ; \stopuseMPgraphic \defineoverlay[triangle][{\uniqueMPgraphic{cell:triangle}}] \starttext \bTABLE[frame=off] \bTR \bTD[nx=2,background=triangle,align=middle] \dontleavehmode a\crlf text \eTD \eTR \bTR[toffset=1mm] \bTD left \eTD \bTD right \eTD \eTR \eTABLE \stoptext It's a dirty trick. I'm sure there's a cleaner way. Does anybody know it? Thanks, Massi

font troubles in MkIV
by Henning Hraban Ramm 13 Apr '20

13 Apr '20

Hi again, as I had to re-setup my computer, I installed all my TeX project fonts in subdirectories of texmf-fonts/fonts/. Most of them are found after one or two forced update runs, strangely not all of them, and ConTeXt won’t load them in the most cases. If I move the same font files to one of the directories in OSFONTDIR, e.g. ~/Library/Fonts, or into the project directory, it works. I don’t see a pattern which fonts are found and which not (except that the only Type 1 font family I tried didn’t work, i.e. only after I installed the TTF version in ~/Libraray/Fonts). I already deleted the luatex cache. Any hints for debugging? (Latest LuaTeX MkIV on macOS 10.14) Best, Hraban

Hi list! Another blog post for you all, tangentially related to ConTeXt: https://dave.autonoma.ca/blog/2020/04/11/project-gutenberg-projects In particular, the conversion from XHTML to Markdown so that pandoc can convert Markdown to ConTeXt may be of interest: https://dave.autonoma.ca/blog/2020/04/11/project-gutenberg-projects/#xhtml-… This is in preparation for part 8 of the typesetting Markdown series, which discusses how ConTeXt can be used to typeset annotations in pandoc's extended Markdown. If there's anything else you'd like to see, let me know. Cheers!

Dear all, The problem is solved by using the namespace of lua as below: I am not sure what I did is the right way. If it is not the right way, please let me know. Thanks for reading.

\type -- extra space in TABLE
by Tomas Hala 12 Apr '20

Hi all, in the following code \starttext \type{6\az12} % \az = \anycommand \bTABLE \bTR\bTD\type{6\az12}\eTD\eTR \eTABLE \stoptext there is a different behaviour of \type: while its parametr in normal text is printed out as is (expected), in the TABLE the extra space is displayed after the command. Is it ok? How could I suppress the extra space? Best wishes Tomáš

\placelist[chapter][counter=realpage] not working
by Pablo Rodriguez 11 Apr '20

11 Apr '20

Dear list, here you have the following sample: \setuppapersize[A6] \setupuserpagenumber[way=chapter] \starttext \placelist[chapter][counter=realpage] \dorecurse{5}{\chapter{Chapter}} \stoptext Why doesn’t \placelist[chapter] use the realpage counter? According to i-context.pdf, \placelist inherits from \setuplist (which also inherits from \setupcounter). I really need that, since the document I’m composing needs chapter and part page numbering independent from the whole document page numbering. Am I missing something or have I hit a bug? Many thanks for your help, Pablo -- http://www.ousia.tk
