Back in the 90s
by Riviera Taylor 13 Apr '24

13 Apr '24

Hello, I was reading about the history of ConTeXt in the Not So Short Introduction To ConTeXt and I have a historical question. I noticed that the PDF specification was published in 1993 yet ConTeXt was invented in 1991. The book suggests that PDF output was handled by the PdfTeX engine in MKII in 2005. What sort of output did the software produce before PdfTeX was introduced? Was this the same as the output produced by the software before the publication of the PDF specification? Kind regards, Riviera she, her, hers https://wiki.contextgarden.net/User:River

\luaescapestring in proper Lua
by Pablo Rodriguez 11 Apr '24

11 Apr '24

Dear list, I have the following sample: \starttext \startluacode function document.print_the_thing(str) context(str) end \stopluacode \unexpanded\def\PrintTheThing#1{% \ctxlua{document.print_the_thing([[\luaescapestring{#1}]])}} \PrintTheThing{a \em b {c}} \stoptext I wonder whether there is a proper way in the Lua code to avoid [[\luaescapestring{}]] in \ctxlua. BTW, [[\luaescapestring{}]] in \ctxlua works better for me, since in my real world document, I’m using str:match() to check whether the string ends with interrogation or exclamation marks ("%?!$"). Many thanks for your help, Pablo

Weird (?) float placement for specific widths of image
by denismaier＠mailbox.org 10 Apr '24

10 Apr '24

Hi, another graphics/floats question: consider the following example %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupexternalfigures [location={local,global,default}] \starttext \placefigure{A Cow}{\externalfigure[cow][ height=.5\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ height=.3\textheight, %height=.4\textheight, ]} \placefigure{A Cow}{\externalfigure[cow][ width=3cm, %width=2cm, ]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \placefigure{A Cow}{\externalfigure[cow][width=2cm]} \stoptext%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% On the first page, the images appear stacked above each other while on the second page they appear next to each other. It took me some time to reproduce this behaviour, and I can't claim to understand what is happening. But it seems to be related to the specific widths of the images. When I change them to other values the behaviour disappears. Is this a bug? Anything I can do about this? Best Denis

Very bizarre bug
by Thomas A. Schmitz 07 Apr '24

07 Apr '24

Hi everybody, this is bizarre, but hear me out: a file that I have has a mixture of xml, TeX and Lua. It compiles cleanly, no problem, on macos and linux. I also have a little raspberry pi on which I have installed lmtx. The file compiles, BUT: it has one additional page. The first page of the document is empty and has the word "on" in the upper left hand corner of the text area. I have checked several times, it always comes out like this. Everything else is exactly the same - context version, file and environment files (everything under git, so really identical). The "on" does not appear if I just make a "hello world" document on the raspi. So my question is: how can I begin to explore where this word creeps in? I suspect it's something in the linux-aarch64 tree or some test for this architecture that is the culprit, but what would be a good way to trace it? All best Thomas

incosistent output of --- dash
by madiazm.eoicc＠gmail.com 07 Apr '24

07 Apr '24

Hi everyone, I'm a bit puzzled because I usually don't get an em-dash when I type tree hyphens. If I use the command \emdash, no problem but when I use the hyphens some days it works... and somedays I see three small hyphens. I tried it on overleaf and of ContextOnWeb with the same inconsistency. If I create a new file it usually works right; but when I overwrite an existing file subtituting a hyphen for three where the dash should be I sometimes get it right and sometimes wrong. It is not the pdf viewer since I get good or bad results in all, the overleaf pdf preview tool, the context on web preview tool and the mozilla integrated pdf viewer. Am I missing something on the use of this ligature? (the question is just out of curiosity, since I plan to create a command that adds a hairspace after or before the dash, since I don't like it to stick to some letters like "o". thanks

statistical charts module re-published
by Henning Hraban Ramm 05 Apr '24

05 Apr '24

Hi, since the Akela server at Mendel University is down since a while, I got no response from Tomáš, and it would be a pity to lose this module, I re-published the statistical charts module at https://codeberg.org/fiee/context-statistical-charts I’ll also put it on modules.contextgarden.net This is version 0.31, tagged by me as 2020-09-11 (date of the presentation). I’m sure there’s a newer version somewhere, at least at Ramkumar’s, and I’d like to update the repo to that. Also the sources for the documentation are missing. Authors, please help me save your work! Hraban

Have a look at these beautiful font designs: https://esadtype.esad-amiens.fr/ Unfortunately the fonts are not available (yet). Take your time to browse the papers about intention, design process etc. I just browsed the dissertation about the (Vietnamese) "Dilinh" font and found the considerations interesting. "Gul" has matching Devanagari & Latin, "Tarisel" has variations from readable text to abstracted lombardic unciale, and "Wierd" has matching deconstructivist outlines for Arabic & Latin… Hraban

what about "textdisplay"?
by Henning Hraban Ramm 02 Apr '24

02 Apr '24

A while ago, I was pointed (by Wolfgang or Hans, I guess) to \start/stoptextdisplay to enhance whitespace handling around images. I wanted to document it, but can’t find it in the sources: $ context --find=textdisplay mtx-context | …/tex/texmf-context/doc/context/sources/general/manuals/ontarget/ontarget-profiles.tex mtx-context | mtx-context | 196 \starttextdisplay … mtx-context | 277 \stoptextdisplay mtx-context | mtx-context | …/tex/texmf-context/doc/context/sources/general/manuals/ontarget/ontarget-standardize.tex mtx-context | mtx-context | 888 \starttextdisplay … mtx-context | 941 \stoptextdisplay mtx-context | These two documents use it and compile flawlessly. What’s on? Hraban

context editor support / syntax highlighting for Pulsar
by Henning Hraban Ramm 01 Apr '24

01 Apr '24

Hi Hans (et al.), find attached a slightly extended version of the "interface" script that can also generate the list of commands in cson format for Pulsar/Atom. It just creates a basic list of commands for syntax highlighting; for a complete plugin, "grammars" and "settings" are missing, see https://codeberg.org/fiee/language-context (Yes, this approach is oldfashioned and a plugin could do a lot more, but I don’t speak TypeScript.) The generated cson file is for "snippets", like in: https://codeberg.org/fiee/language-context/src/branch/master/snippets/langu… There, I added information from the interface files and also from the wiki, if existing. I don’t know how to do that in the lua script. --- function flushers.pulsar(collected) for interface, whatever in next, collected do local commands = whatever.commands local environments = whatever.environments local result, r = { }, 0 r = r + 1 ; result[r] = "'.text.tex.context':\n" for i=1,#commands do r = r + 1 ; result[r] = format("\t'\\%s':\n",commands[i]) r = r + 1 ; result[r] = format("\t\tprefix: '%s'\n",commands[i]) -- can we have some information? --r = r + 1 ; result[r] = format("\t\tdescription: 'level: primitive; interface: i-tex.xml'",'') -- no URL if command starts with "stop" r = r + 1 ; result[r] = format("\t\tdescriptionMoreURL: 'https://wiki.contextgarden.net/Command/%s'\n",commands[i]) end io.savedata(format("language-context-%s.cson",interface), concat(result),"\n") end end --- Also, the "en" interface is empty, everything is in "common", so the iteration over interfaces makes no sense here. Actually, Atom/Pulsar could work with a tree sitter parser (https://github.com/pmazaitis/tree-sitter-context) but I don’t know how to use it. [TextMate] For TextMate and other editors that use TM bundles, it might make sense to update https://github.com/pgundlach/context.tmbundle At least the list of commands could be automatically converted from the interface files, but it’s more involved than what mtx-interface does. [Visual Studio Code / VSCodium] BTW, is the ConTeXt language server for VS Code public anywhere? (Ramkumar KB promised…) Or is "mtxrun --script=vscode --lsfile" the same? Hraban

upload
by Hans Hagen 01 Apr '24

01 Apr '24

Hi, There is a new lmtx upload. -- The svg inclusion via metapost has been upgraded and cleanup a bit, using some more recent metapost features. There are some new (not yet all documented metapost) features. -- In the process, support for LCH colors has been added, which is documented in the (eg luametafun manual). -- The math manual is not yet there because we were distracted by improving support for envelopes (penbased outlines) in metafun. This is still work in progress, some is present and discussed in the manual, and we'll come back to that sometime next month. Given the next item, we also might need to change some in the manual (different focus). -- Because we have users who have to conform to the European Accessibility Act we have been wondering how to deal with that and at Mikaels place there are two demands: distinctive colors and tagging and especially math (somehow validators love to check that). Colors never were an issue as they can be controlled, and tagging math neither, especially because nothing was/is done with it anyway, but ... we are happy that we found a reasonable (more modern and future proof) way out. As explained / shown in the attached document we're basically forced to choose a different approach with math (a pity as we worked hard to get the rendering right but the attached file works fine in the viewers that we tested). -- We like to hear from users what other demands wrt accessibility there are. We're not interested in the (commercial) big money aspects (of pdf and tagging) nor in the politics behind it (changes over time). What are the demands, so that we can see how to make it work or just work around it (as it's kind of boring to cook uyp complex features , esp compared to playing with metapost). -- Furthermore .. the usual bits and pieces as discussed on the list and otherwise. -- If you have troubles (crash) you need to wipe the cache due to a change in lua bytecode storage (no easy way to catch it).

How to get an image to fill the maximum available space?
by Joel 30 Mar '24

30 Mar '24

I have code like this: \placefigure[here, force]{my caption}{% \externalfigure[#1][frame=on, maxheight=1.2\textwidth, maxwidth=\textwidth]% }% I need some images to appear in a book. I need them to keep their proper ratios, but scale up to the maximize the available space. The image can't be more than \textwidth wide, and can't ever be more than 1.2\textwidth high. The problem I am getting with this code, and it does seem to be limiting the images to be not bigger than those two dimensions above, is some of the images, for reasons I can't understand, are appearing really tiny and aren't scaling up to fill as much space as is possible. I can't explain why this is happening--the images themselves are very very high resolution. Is there any way to modify the code to make sure the image stretches up to be the biggest it can, without exceeding the sizes I've listed? --Joel
