Is there a 'sized' command equivalent to \colored?
by Gerben Wierda 23 Apr '20

23 Apr '20

I can directly colour a text in rgb by doing \colored[r=0.8,b=0.6,c=0.4]{Text}. Suppose I want to hard code a piece of text as 12.8pt, is there a simple way to do that directly like with \colored for colour? G

problem using LMTX
by Charles Doherty 23 Apr '20

23 Apr '20

The print-out below is from two runs on a Newsletter that I produce. Taco kindly told me to add \loadmarkfile{page-mul} to my input file some months ago to solve a problem with footnotes. I use an engine in TeXShop and I get the result 1) below (which is what I want) in the first example. I am happy to keep using this version of ConTeXt. However, as a matter of interest, I installed LTMX in a separate folder and used a different TeXShop engine directed to that installation and when I do I get the bottom result 2). As you can see there is a lot of white space between the end of the text and the footnotes in that run. This happens with the articles in my newsletter that have footnotes. Can this be fixed? Very best wishes and thanks for past help.

Setting up macvim in mac os catalina to work with LMTX
by Jan-Erik Hägglöf 23 Apr '20

23 Apr '20

Hi ! I am curious about testing macvim and it seems doing fine in edit mode. But how do i set up the typesetting engine? As far as I understand, there is, the command :ConteXt with guidance from the wiki https://wiki.contextgarden.net/Vim <https://wiki.contextgarden.net/Vim> But I do not understand how to customize it to be directed to the path to my engine I’ve installed the LMTX in /Users/janneman/context-osx-64/ The installation works fine in TeXshop but still an error shows up in macvim and the message dissappears very quick so there is not much time to read the cause of error. I have created the subdirectory .vim/ftplugin/ and put the context.vim file there also the corresponding in .vim/compiler/context.vim which is copied from the program located in /usr/local/Cellar/macvim/8.2-163/MacVim.app/Contents/Resources/vim/runtime So, how do I get this up and running? Thanks in advance Regards /Janne

lmtx & lohit-devanagari fonts
by Saša Janiška 23 Apr '20

23 Apr '20

Hello! I'm working on a small presentation for an upcoming video meeting and started writing some points in Markdown. After using Pandoc to convert I noticed that *.pptx file does contain everything, but if I try with ConTexT, then Devanagi and some diacritics are missing. By inspecting *.pdf file produced by: Pandoc --> PPTX --> LibreOffice --> PDF I can see that Lohit-Devanagari font is used for Sanskrit and I have it installed on my Fedora (fc32) desktop machine. Here is the test file: \starttext ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते । सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते ॥ ६२ ॥ dhyāyato viṣayān puṁsaḥ saṅgas teṣūpajāyate saṅgāt sañjāyate kāmaḥ kāmāt krodho ’bhijāyate Translation: ``While contemplating the objects of the senses, a person develops attachment for them, and from such attachment lust develops, and from lust anger arises.'' \stoptext which I would like to quote - I am somewhat familiar with latin transliteration via diacritics, but completely ignorant in regard to Devanagari - but wonder what is required to make ConText (lmtx) typeset it? Here is the log file: $ context t.tex resolvers | formats | executing runner 'run luametatex format': /home/gour/opt/lmtx/tex/texmf-linux-64/bin/luametatex --jobname="t"

Text editors don't execute ConTeXt standalone
by Jairo A. del Rio 23 Apr '20

23 Apr '20

I've recently installed the ConTeXt standalone following the instructions listed below: https://www.contextgarden.net/Ubuntu However, commands as "context" and "mtxrun" only work when executed from terminal. When I specify these commands in a text editor (TeXstudio, Textadept), they just don't work, even with a full path specified. On the contrary, commands as "tex" or "latex" from TeX Live are visible to editors. How to fix that?

Best way to create a large number of documents from database
by Mojca Miklavec 23 Apr '20

23 Apr '20

Hi, I have been asked to create a few thousand PDF documents from a CSV "database" today (which I can easily transform into any other form, like XML or a lua table or TeX definitions or whatever). Generating a few thousand pages would be straightforward, but I'm sure there are some clever ways to handle this scenario as well, I'm just not aware of them :) One option is that I quickly draft a python script that creates a few thousand TeX documents and compiles them individually, but it might be easier if there was a way to just create a single template document and then run something like context --some-params --N=42 --output=document-0042.pdf template.tex or something along those lines. What's the best approach with the existing functionality? I would be more than grateful for any hints. Thank you very much, Mojca

Text size with lmt_text [ ]
by Fabrice Couvreur 22 Apr '20

22 Apr '20

Hi, As an extension of this discussion https://mail.google.com/mail/u/0/#inbox/QgrcJHsNlRfcqCPHBTrnSFbJKjGPwjbJnLL… (thanks to Wolfgang), I used the MetaFun interface with lmt_text [] ; I managed to pass the text and color parameters while I did not succeed using textext (). My problem is the size of the letters which is too small. Thank you. Fabrice \usecolors[xwi] \definecolor [prune] [r=1.29,g=.20,b=.83] \starttext \startMPcode vardef card(expr s, c) = image( draw fullsquare xyscaled (2cm,4cm); draw fullsquare xyscaled (1.8cm,3.8cm) withcolor \MPcolor{violet}; draw lmt_text[ text = s, color = c, style = "bold", ] ) enddef; draw card("A",red) rotatedaround((1cm,2cm),5); draw card("L",green) rotatedaround((1cm,2cm),-5) shifted(3.5cm,0); draw card("E",blue) rotatedaround((1cm,2cm),5) shifted(6cm,0); draw card("A","prune") rotatedaround((1cm,2cm),-5) shifted(9cm,0); \stopMPcode \stoptext

mtxrun fontloader in recent standalone
by Benjamin Buchmuller 22 Apr '20

22 Apr '20

I’ve just updated to the most recent standalone ConTeXt ver: 2020.01.30 14:13 MKIV beta fmt: 2020.4.22 (LuaTeX 1.11.1) and I’m running now into troubles with system font indexing: mtxrun --script fonts --reload locates fonts in macOS directories appropriately (*.afm fonts placed in .../tex/texmf-fonts are not found, but at the moment I don’t care too much), however it resolves only to a single font variant for *.ttc instead of all variants: mtxrun --script fonts --list --all --pattern=helvetica helvetica helvetica helveticalightoblique /System/Library/Fonts/Helvetica.ttc 6 helveticalightoblique helvetica helveticalightoblique /System/Library/Fonts/Helvetica.ttc 6 helveticaneuedeskinterfaceheavy helveticaneuedeskinterface helveticaneuedeskinterfaceheavy /System/Library/Fonts/HelveticaNeueDeskInterface.ttc 10 helveticaneuethinitalic helveticaneue helveticaneuethinitalic /System/Library/Fonts/HelveticaNeue.ttc 14 As a consequence, when I run \definefontfamily[mainface][ss][Helvetica Neue] \setupbodyfont[mainface, 12pt, sans] I get the light oblique variant instead of the regular one. I have tried to fix this via a \definefontfamily[mainface][ss][Helvetica Neue][tf=style:normal] but apparently I understand too little about this setup altogether … Thanks already for any suggestions!

METAPOST: How do I get this 'max' cutafter to work?
by Gerben Wierda 22 Apr '20

22 Apr '20

I have these two paths, but cutting doesn’t work because the path to be cut takes the wrong intersection regardless of how I direct the path to be cut after (reverse or not). The path to cut after is a triangle with the base horizontal and the path to cut is a vertical line. The top of the triangle is the endpoint of the line and is selected as intersection by cutafter. This happens also if I reverse the triangle path, strangely enough. I have an alternative cutting algorithm, but that cuts as long as the length of cuttings is not 0, which is the case at the top too, so it won’t cut further. I need a reliable algorithm to make a ‘maximum cutafter’. What might be a good approach?

accessing prd file from component file
by Alan Bowen 22 Apr '20

22 Apr '20

When my component files were in the same directory as my component files, the line %! TeX root = prd_whatever allowed processing the component file from the component file. (I use TeXShop for this.) The project structure has been changed: the component files are in a subdirectory of the directory that has the prd file. Now, %! TeX root = prd_whatever no longer works. (E.g., it cannot find the environment files called in the prd file.) Is there a way to restore processing from the component file. My experiments are near to wearing out the “error” message/page.
