definedocument, begin & closing
by Henning Hraban Ramm 06 Jul '23

Hi, if I use \startdocument, the setups "document:start" and "document:stop" get inserted at the beginning and end. But if I define my own document, it doesn’t work. What’s wrong? """ \definedocument[presentation] \startsetups[presentation:start] {\bfd\documentvariable{title}} \stopsetups \startsetups[presentation:stop] Thanks for all the fish. \stopsetups \startpresentation[title=Something] anything \stoppresentation """ Hraban

Arch linux package for context lmtx
by Aditya Mahajan 06 Jul '23

06 Jul '23

Hi, I maintained a AUR (Arch User Repository) package for context lmtx which was called luametatex. Arch recently introduced an official extra package for luametatex (the binary) called ... well ... luametatex, which means that my package has a name conflict with the official package and hence was deleted. Arch also now provides an official texlive-context package for context. I assume that it syncs with texlive. At present, texlive-context includes ConTeXt 2023.03.10. So, I think that the AUR package is still useful. It is essentially just a wrapper around the official install scripts and provides the latest release of context lmtx (and user modules). So, I am renaming my old `luametatex` package and am re-releasing it as `context-lmtx-bin`. To use it: git clone https://aur.archlinux.org/context-lmtx-bin.git cd context-lmtx-bin makepkg sudo pacman -U context-lmtx-bin-<release-date>.pkg.tar.zst This will install context lmtx in /opt/context-lmtx. This is in parallel with any system installed context. I also keep the old .tar.zst files around. That makes it easy to revert back to a previous version in case there is something that doesn't work as expected in the latest release. Note that by default the following third user modules are installed: 'filter' 'visualcounter' 'vim' 'tikz' 'typescripts' This is obviously a biased list corresponding to what packages I use. To install other packages, simply open the PKGBUILD file and change the _module variable defined as: _modules=('filter' 'visualcounter' 'vim' 'tikz' 'typescripts') You can change it to _modules=('--all') to install all modules. When using the package for the first time, run source /opt/context-lmtx/setuptex mtxrun --generate For any future runs, simply use source /opt/context-lmtx/setuptex once in your shell. This adds /opt/context-lmtx/texmf-linux-{32,64}/bin to the PATH variable, so the binaries provided by context-lmtx are found before the system binaries. The setuptex file provides a `resettex` function which removes the above path from the PATH variable. The setuptex file also sets a variable CONTEXDIST to 'lmtx'. This can be used to set the value of PS1 variable (or similar) of your shell prompt to add a visual reminder of which context installation you are using. Let me know if there are any issues with this install. Aditya

MP setup for a progress bar
by Henning Hraban Ramm 05 Jul '23

05 Jul '23

Thanks to Taco, Robbert and Jules for their work! I used the downtime to setup a presentation style with a progress bar in the footer. But I get the same (first page) graphics on all pages, and the footer background appears under the text area as well as under the margins. * I thought \useMPgraphics would be enough to re-calculate on every page? * How can I set a background to the footer area, but page width? * I tried \overlaywidth as well as OverlayWidth in the MP graphic – how do I get the page size? """ \setuppapersize[SW] \startuseMPgraphic{Blocks} fill unitsquare xysized (800 * RealPageNumber/NOfPages, 50) withcolor blue; \stopuseMPgraphic \defineoverlay[Blocks][\useMPgraphic{Blocks}] \setupbackgrounds[footer][background={Blocks}] \starttext \dorecurse{10}{\recurselevel\page} \stoptext """ Hraban

The use of \textfont in ConTeXt
by Leah Neukirchen 05 Jul '23

05 Jul '23

Hi, I've been porting Paul Taylor's prooftree.sty (https://www.paultaylor.eu/proofs/) to ConTeXt, which seemed quite easy. There's just one adjustment to make: 291c292 < \else \dimen6=\fontdimen22\the\textfont2 % height of maths axis --- > \else \dimen6=\the\dimexpr\triggeredmathstyleparameter\Umathaxis % height of maths axis It seems that ConTeXt stores the math font in \textfont0 instead of \textfont2 as LaTeX does. Now my question is: is \textfont2 used at all? (I grepped occurences of \textfont0 and \textfont1) Then I could just copy the \textfont0 to \textfont2 before loading the macro and would not require any patches. -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

mplib: identifiers starting with units
by Leah Neukirchen 05 Jul '23

05 Jul '23

Hi, I've been trying to use the 'cmarrows' metapost library with ConTeXt/mplib. Essentially it's a thin wrapper around the cmr metafont sources to get the arrowheads. This triggers an incompatibility between mplib and classic mpost/mf: pt#:=1pt; In MetaFont/MetaPost pt# is an allowed identifier, but in mplib this results in a parse error. Unfortunately, pt# is used all over the cmr sources... would it make sense to allow using this again? -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

After erasing the font cache and regenerating LM was doing it right again.

Most often, I’m isolated working with ConTeXt, most collaborators using LaTeX. Of course, some have seen the amazing things we can do with ConTeXt, and are using it a bit, but installation remains a challenge for most of them. Being able to work and share an overleaf project is a way to work in a collaborative way in ConTeXt (and Metafun of course !). > > Aditya Tanks agin for the tip ! Fabrice.

Tried a few times to no avail. -- A novice asked the master: "I have a program that sometimes runs and sometimes aborts. I have followed the rules of programming, yet I am totally baffled. What is the reason for this?" The master replied: "You are confused because you do not understand the Tao. Only a fool expects rational behavior from his fellow humans. Why do you expect it from a machine that humans have constructed? Computers simulate determinism; only the Tao is perfect. The rules of programming are transitory; only the Tao is eternal. Therefore you must contemplate the Tao before you receive enlightenment." "But how will I know when I have received enlightenment?" asked the novice. "Your program will then run correctly," replied the master. -- Geoffrey James, "The Tao of Programming"
