Suppressing headers and footers on blank pages before pagebreak at the end of a chapter.

Hi list, I typeset my first project with ConTeXt, a small booklet with some chapters, frontmatter, no headers, but pagenumbers in the middle of the footers. I use two environment files. The text is split into component TeX-files. All is structured by a project and a product file. Now I have run in some problems, I couldn’t solve with the garden and the archives of this and stackexchange’s list. But I’m sure that it is almost too simple for you experts. Let’s start with one. As intended, a new chapter starts on a right/odd page. If the chapter before ends on a right page, too, there should be a blank left/even page. But in my case there is the pagenumber in the footer – which looks more horrible than an orphan line. A. Which setting in which setup or definition gives a command like: suppress/skip/hide the header, footer and margin of last page of a chapter, if the text area is empty. B. More elaborate, a set of commands could – distinguish between headers, footers, an margins and – extend the commands on those pages at the end of the chapters – that do not show any text within the last line of the text area, i. e. the very last page of a chapter (even, but whith some text) – or the second last page (odd, with some text, before a complete blank even page). A book design according to (A) is standard. I’m sure there is a solution in ConTeXt. (B) can be found often, at least in books from pre-computer times. Ralf

Parenthesis error in metapost
by Mikael Sundqvist 07 Apr '21

07 Apr '21

Hi, the following code has been working before: \starttext \startMPpage[instance=decimalfun] draw function(1,"x","x*sin(x)",0.5,1,1/100) scaled 1in; \stopMPpage \stoptext Now (with an updated ConTeXt) I get an error: metapost > loading 'metafun' as 'metafun.mpxl' using method 'decimal' metapost > initializing number mode 'decimal' metafun > log > metafun > log > error: Missing ')' has been inserted metafun > log > metapost > log > <to be read again> metapost > log > ( metapost > log > <scantokens> x*sin( metapost > log > x) metapost > log > <to be read again> metapost > log > ) Maybe I have done something wrong earlier, but I cannot see any unmatched parenthesis now. /Mikael

"Scheduled" downtime of the contextgarden server
by Mojca Miklavec 05 Apr '21

05 Apr '21

Dear ConTeXters, There will be a "scheduled" downtime of the contextgarden.net server for maintenance reasons (the part that's hosted in Slovenia; that excludes wiki & modules, but includes the old distribution, buildbot CI, CTAN, TL pretest & w32tex mirror, ...) in one of the following days. It's not yet clear when exactly the downtime will happen (and all the lockdowns etc. make that even harder to predict) and I'm also not entirely sure how long it will take, this is just to give you a notice upfront. Mojca (PS: I hope that TL 21 won't need any further builds, else we can postpone this.)

SVG comments, transparency, and extended font styles
by Thangalin 03 Apr '21

03 Apr '21

Issues encountered with version 2021.03.31 18:04. 1. Comments in SVG % SOF \startbuffer[svg] <svg viewBox="0 0 100 100" xmlns="http://www.w3.org/2000/svg"> <g><circle cx="50" cy="50" r="20"/></g></svg> \stopbuffer \starttext \placefigure{}{\includesvgbuffer[svg][conversion=mp]} \stoptext % EOF Expected: Black circle, no border, comment lines ignored. Actual: Empty square. 2. Transparent stroke % SOF \startbuffer[svg] <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <polygon fill="#eeffff" stroke="transparent" points="500,10 500,0 0,0 0,10" /> </svg> \stopbuffer \starttext \placefigure{}{\includesvgbuffer[svg][conversion=mp]} \stoptext % EOF Expected: Light cyan rectangle, no border (it's transparent). Actual: Light cyan rectangle with visible border. 3. Inkscape font specification We discussed this previously: Inkscape extends the SVG specification with a custom style class ("-inkscape-font-specification") that allows its users to refine font styles. % SOF \startbuffer[svg] <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 154.6 19.3" width="155" height="19"><text x="-6.7" y="-2.3"><tspan x="-1.9" y="15" style="-inkscape-font-specification:'Roboto, Ultra-Light';font-family:Roboto;font-size:20px;font-weight:200">Roboto Ultra-Light</tspan></text></svg> \stopbuffer \starttext \placefigure{}{\includesvgbuffer[svg][conversion=mp]} \stoptext % EOF Expected: "Roboto Ultra-Light" appears in Roboto Ultra-Light font. Actual: Empty square. Supporting this via MetaPost would help maintain backwards compatibility (with ConTeXt invoking Inkscape). Thank you!

Floating objects next to text mess up paragraph spacing
by Daniel Barker 01 Apr '21

01 Apr '21

Hi all, I have noticed that placing a floating object next to text with location "left", "right", etc. seems to move the current paragraph slightly up, resulting in too little space between the current and previous paragraph. This can be seen quite clearly in the output of the following example: \setupbodyfont[dejavu, serif, 12pt] \starttext \samplefile{lorem} \startplacefigure[location={right, none}] \framed[width=3cm, height=2cm]{graphic} \stopplacefigure \samplefile{lorem} \samplefile{lorem} \stoptext I am using the current (2021.03.31 18:04) version of ConTeXt LMTX. On ConTeXt live, which seems to be running an older version, this does not occur, i.e. the spacing is even, as I would expect it to be. I assume this is a bug, or am I doing something wrong? Thank you, Daniel

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 -----------------------------------------------------------------
