README for pending new subscribers March 2021
by Taco Hoekwater 01 Apr '21

01 Apr '21

Hi all, Regretfully, we have had problems with a hacker messing with the html subscription page of this mailing list. In mitigation, we have disabled web - based subscription requests completely. From now on, subscription to this mailing list can only be requested by sending an email message to ntg-context-request(a)ntg.nl with “subscribe" as the Subject. Unfortunately, it was impossible for us to differentiate between "hacked" and “legit” subscription requests made during the month of March 2021 so to prevent our mail server from being blacklisted as email sender we have had to discard all pending subscription requests. This means that anyone that has tried to subscribe to ntg-context during the past month (that has not received a confirmation message from mailman welcoming them to the mailing list) will have to re-start the subscription process. Apologetically, Taco — Taco Hoekwater E: taco(a)bittext.nl genderfluid (all pronouns)

KeenWrite + ConTeXt: a sneak peek
by Thangalin 01 Apr '21

01 Apr '21

Hi all! Here's a screenshot showing a PDF file created using ConTeXt, exported from my text editor, KeenWrite: https://ibb.co/SNg19Sn Notice the areas highlighted with rounded red rectangles: * Export PDF button (top-left) * Exported file name and ConTeXt processing time (lower-left) * Settings for the --path option (preferences dialog, top) * Settings for the --environment option (preferences dialog, bottom) * Document stats (lower-right) The app has a preview tab that is updated in real-time, which can be repositioned or closed and is shown to the left. Shown on the right is the PDF document generated using ConTeXt by clicking the export PDF button. App screenshots: https://github.com/DaveJarvis/keenwrite#screenshots Thoughts? Ideas for ConTeXt integration features? P.S. Thank you for all the hard work that has gone into ConTeXt: it's truly a splendid piece of software to use.

new upload
by Hans Hagen 31 Mar '21

31 Mar '21

Hi, I uploaded a new version. However, because of some new feature there can be (unwanted) side effects wrt hyphenation (should not be but who knows). As a follow up on Denis mails about ligature prevention, we now have a mechanism called language 'goodies' analogue to 'font goodies'. For practical reasons this permits (high performance) plugs into the mechanism that also deals with hyphenation. Basically we can have some feedback loop but more about that later (Denis, Wolfgang and I need to play with all this and settle on the interface). Although all can be done in pure lua (and i might add that at some point) this particular mechanism plugs into the hyphenator so that we get no real performance hit (I can proabbly improve it if really needed but let's first see if users complain.) Here is an exmaple (to be default or not?) \setuplanguage [de] [goodies={lang-de.llg}] that has to come before a lkanguage gets activated (for now). In addition to exceptions one can do \startlanguageoptions[de] Zapf|innovation \stoplanguageoptions to prevent a ligature between f and i and \startlanguageoptions[de] Zapf=innovation \stoplanguageoptions to make it into a compound word (use both to prevent ligatures too). There's more to come once we get the full picture. I leave it to Denis to organize the collection of words and definitions that go into a goodie file. Hans ps. Sometimes I wonder if for every new feature added we should drop an old maybe useless one, like some of the obsolete pdf stuff or features that seem to be persistently broken or weird or unpredictable in viewers. After all evolution also takes care of removal. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Nested structure of files loaded by input
by denis.maier＠ub.unibe.ch 30 Mar '21

30 Mar '21

Hi, I have file main.tex that loads various subfiles that are placed in a subdir : \starttext \input subdir/chapter1 \stoptext Chapter1.tex itself loads some other files that are also placed in the subdir directory : \starttext \input subfile1 \stoptext Subfile1 : \starttext Asdf \stopttext Now, when in the subdir `context chapter1` and `context subfile1` both work. But in the main directory this here fails : context main -> < input file 'subfile1' is not found, quitting' What am I missing ? Does \input resolve filenames according to the CWD, not to the location itself is located ? How can I make that work? Best, Denis

Issue with \handletokens\with and Lua-defined macros
by Jairo A. del Rio 29 Mar '21

29 Mar '21

Hi list! See the following example: \startluacode userdata = userdata or {} --Toy example --My actual function receives an argument, but the problem remains the same userdata.myfunction = function() return "343327959841638047651959775267761420323" .. "657838053757849835434002826851807933276" .. "324327913964298509889902373459201557839" .. "84828001486412574060553756854137069878601" end interfaces.implement{ name = "myfunction", public = true, actions = function () context(userdata.myfunction()) end } \stopluacode \def\colorfulnumbers#1{\colored[h=\luaexpr{40*#1},s=1,v=1]{#1}\ }% \starttext %It doesn't work %\handletokens{\myfunction}\with\colorfulnumbers \expandafter\handletokens\expandafter{\myfunction}\with\colorfulnumbers \stoptext As readily seen from my example, I want to color each figure of the numbers generated by a Lua function. However, the use of \expandafter's is cumbersome in this case. I don't want to loop over the result in Lua because I want to be able to apply \handletokens...\with... (or another macro with a similar purpose) with different macros at the TeX end once Lua has delivered results. How should I do it in ConTeXt? Thanks in advance. Cordially, Jairo

Radial gradient stops in SVG images
by Thangalin 29 Mar '21

29 Mar '21

In the latest release, SVG radial gradients appear to apply colour stops as solid black. Removing the <stop> elements produces a solid colour, but without a radial gradient. Hans may be aware of the issue. Meanwhile, here's an MWE. Save as gradient.svg:  <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 215.9 279.4" height="1056" width="816"><defs><radialGradient r="153.278" fy="276.602" fx="101.83" cy="276.602" cx="101.83" gradientTransform="matrix(0.41308681,-4.1069042e-8,4.7549103e-8,0.47826553,59.765073,10.270449)" id="A" gradientUnits="userSpaceOnUse"><stop offset="0" stop-color="#f9f9f9" stop-opacity="0"/><stop offset="1" stop-color="#4c1300" stop-opacity=".26"/></radialGradient></defs><g fill-rule="evenodd"><path d="M.127.127h215.646v279.146H.127z" fill="#f8da95"/><path d="M10.54 38.525h182.579v208.07H10.54z" fill="url(#A)" opacity=".75"/></g></svg>  Save as gradient.tex: % SOF \starttext \placefigure{}{\externalfigure[gradient.svg][conversion=mp]} \stoptext % EOF Expected: A light-brown, translucent, radial gradient region appears on the page. Actual: A solid, opaque, black region appears on the page. Environment: Xubuntu Linux 5.8.0-48 (clean install on VirtualBox) ConTeXt version 2021.03.27 19:09 Cheers!
