Hi, It has been a while since there was an updaste but there it is. The most significant 'changes' are: - more automatic adaption to double sided page properties in metafun (lmtx) ... blame sreeram and me for messing up - more extensibve support for indic fonts which sreeram has documented on the wiki (fonts, translutaration etc) and - improved math rendering to be documented by by mikael in an upcoming manual ... it tooks a couple of months so it is supposed to have some impact. before we move on the the structural compoments and see what can be done beter there, we decided to release the first stage that deals with: = fixing font properties; we don't expect fonts to be improved so that's the route we follow = extensive inter atom spacing (we have many more math classes, some in the engine, some in context) and everything can be controlled (the old pairwise spacing primitives have been replaced by a more general mechanism, including support for fast setup of categories and inhertance from other classes) = idem for inter class penalties, including granular control over line breaks using a system of (in/de)creasing penalties = auto-fenced inline material across lines and linebreaks in molecules (read: complex atoms) = taking stretch and shrink in encapsulated atoms into account in linbreaks (using some new box related mechanism that is also available in text and will be explained later) = spacing at the edges that should not be there but always was there as side effect of the engine is now removed; as with other new features this can be controlled (we have rulesets for atoms to which we can add more in the future) = more detailed control over (skewed) fractions, (flattened) accents, (sized) fences, radicals ... there was already a lot there but it now combines with mentioned spacing (when relevant the context macros have been adapted to control this which is a bit cleaner) = we have a new built in muskip (tiny) but as we have an inheritance system as well as binding to variables one can set up extensive spacing models register and constant binding; the currently set values are based on math typesetting references; in the future we might have additional ones = although we did handle primes already rather transparent in mkiv / lmtx, inconsistency in fonts made us decide to make primes first class properties of atoms and molecules which means that we now have: pre super/subscripts, post super/subscripts and primes; this permits nicer anchoring under parameter control = there are more font parameters to control matters (they are not in open type but we sort of assume they are); the options that we had to control how the engine deals with fonts are now driving the process (without them being set not much is applied) and we basically assume open type fonts (where one can enable engine options for those kind of fonts but also for traditional); some experimental options for testing are gone = in the process tracing for what is done in math by the engine has been extended (mostly for ourselves) = instead of auto patching math fonts most is now under control of the goodie files; user can (as usual) make their own, but also ask Mikael to add missing bits and pieces (wrt dimensions) = most known math fonts are dealt with but there are a few exceptions: we no longer consider asana to be useful (it doesn't pass our qa and needs too much patching); erewhon is also troublesome (dimensions, missing shaped) as is concrete (idem) so we decided not to waste too much time on them now = we probably need to freeze math fonts in the distribution and only update when we know what has been changed = we got rid of quite some artifacts that normally go unnoticed (like tiny added spaces that result from always applied spacing even if not needed and/or to compensate for glyph features like too much or little side bearing): by fixing inconsistencies in fonts we could get rid of all and therefore inter atom spacing is what does the job; once you know it, you see it and there is no going back = because we zoom in we notice these things but much went unnoticed (or was just accepted) for years; it means that we think some of the things we did qualify as math micro typography (like it or not) and it does mean that documents can render differently (unlikely for display, propably also for inline unless you have plenty of math in a paragraph) == our objective has been to make it easier for users and to get rid of explicit spacing; for that we also introduced commands for differentials (that have their own class), imaginary numbers (also have their class) and we added exponential as class; fwiw, digits and factorial are classes too so again spacing has been optimized for them = whatever i forgot in the meantime mikael will add to this list There is a rough description in the 'ontarget' document. We hope you enjoy it, at least we did (and so, as we're not finished yet).

tilde character
by Henning Hraban Ramm 14 Mar '22

14 Mar '22

Hi, I’ve a stupid question: How do I get the default tilde character from a font? ~ is a fixed space \texttilde gives a tilde accent \utfchar{0x007E} yields a space (probably the same as ~) Hraban

intercolumn pull quotes typesetting
by Garulfo 13 Mar '22

13 Mar '22

Hi all, what would be the prefered way to typeset pull quotes (with \startcolumns or even \startcolumnset if needed) between 2 columns. Examples: https://tex.stackexchange.com/questions/45709/how-do-you-create-pull-quotes https://www.societal.fr/sites/societal/files/old_site/societal-46-6-boiteux… Thanks for your ideas and solutions.

Errors compiling the MetaFun manual
by Marco Patzer 13 Mar '22

13 Mar '22

Hi! I tried to compile the MetaFun manual from /doc/context/sources/general/manuals/metafun and ran into a few issues. I don't know if that's expected or if it's supposed to work on a current LMTX. Attached are the first two issues. It takes a while to boil it down to MWEs. Let me know if I should report the other errors, too. I'm not using the failing bits myself, so I don't need fix for that. Motivation is to help find issues with the current release. Marco

Bibliography (follow up)
by Willi Egger 12 Mar '22

12 Mar '22

Hello, I am following up on my previous mail from 22-02-2022… In the meantime I was able to find out, what the problem with the crippled publication in the list was. — After adapting the *.bbl file it now works. — However there is most probably a bug in the setup of the list-layout. What you can see in the attached pdf, the issue-number is collated to the title, no comma no space. I would be really happy, if someone could confirm this problem. Attachments: MWE including the publist-test.tex, publist-test.bbl and the publist-test.pdf

help with facing page image
by jbf 12 Mar '22

12 Mar '22

I wonder if someone can help me untangle the current little mess I seem to be creating! Author wants an image on facing page to each of 10 chapters in the bodypart of the document. Assume that everything else is working properly for this document (double-sided etc.), but other than before chapter 1, I can't seem to get my facing page image to appear where it should! A question along these lines (but not quite the same) was asked back in 2019, so I started with what seemed to me to be the simplest response to this question. Here is what I have to get the image before Chapter 1 in bodymatter: \startbodymatter \definelayer[mylayer] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth,height=\paperheight] % let the layer cover the full paper \setlayer[mylayer] [hoffset=2.5cm, voffset=3cm] {\externalfigure[Chapter1.jpg][width=.9\textwidth]} \doifoddpageelse {} {\pushbackground[page] \setupbackgrounds[page]%[background=color,backgroundcolor=red] [background=mylayer] \page[empty] \popbackground} \startchapter[title={Prelude}] etc..... This correctly places the Chapter1.jpg on the facing page to Chapter 1. My problem comes with Chapter 2, since Chapter 1 finishes on an even page, and this means I would need a blank odd page to follow that so that Chapter2.jpg (a different image to the first) can be on the verso of that and the Chapter itself would then start on the odd page facing that. I think the \doiffoddpageelse command above is only meant to work when a chapter ends on an odd, not an even page, but I do not know what alternative command to give. Repeating the above set of commands prior to \startchapter for chapter 2 places the image, naturally enough, behind the last page of text for Chapter 1, which is unacceptable, so I thought I could simply add a blank page or two after the chapter and it would all fall into place. I tried various ways of doing that (e.g. \page[+2], or using makeup pages), and while I can add pages that way, I can't get the image to appear. No doubt the solution is simple enough. It might also lie in the \setuphead[chapter] arrangement too. I've tried page=yes there, but to no avail. I also tried \ startsetups[chapter:before] with the pushbackground etc command and added that in with before=\directsetup{chapter:before} as suggested in the wiki, but couldn't get that to work either. By that stage I was so tangled up in the problem I may not have been able to think straight :-). Somehow, though, I think most of the elements are there. Any help would be appreciated. Julian

interlinespacing in margin notes – solved
by Henning Hraban Ramm 10 Mar '22

10 Mar '22

Hi all, esp. Hans and Massimiliano, yesterday in the online meeting we discussed (again) my margin notes problems. A quite minimal setup is shown below. My remaining problem was that the footnotes always used the interlinespacing (baseskip) of the main text. Finally I found the reason in my typescript file: \definefontfeature[default][dimensions=strut] (I guess I tried to solve the irregular line spacing with that setting.) Thank you for your patience! Now I need to adjust the linespacing and page breaking in all other parts of my current book... Hraban """ \usemodule[ipsum] \showframe \setuplayout[ width=100mm, rightmargin=50mm, rightmargindistance=6mm, ] \setupbodyfontenvironment[11pt][ em=italicface, text=11pt, small=8pt, interlinespace=14pt, ] \definebodyfontenvironment[8pt][interlinespace=8pt] \setupbodyfont[rm,11pt] \define\PlaceFootnote{% \inouter[ width=50mm, stack=yes, ]{% \placelocalnotes[footnote][before=,after=] }} \setupnote[footnote][ location=text, indenting=no, bodyfont={ss,8pt},% footnote text style next=\PlaceFootnote, align=flushleft, ] % footnote marker in text \setupnotation[footnote][ way=bytext, indenting=no, distance=0.25em, ] % footnote text \starttext \dorecurse{10}{ \ipsum[alternative=lines,n=random,language=la]\footnote{\ipsum[alternative=lines,n=random,language=la]} \ipsum[alternative=lines,n=random,language=la]\par } \stoptext """

"Flushbottom" / \setupalign[line] in LMTX
by denis.maier＠unibe.ch 09 Mar '22

09 Mar '22

Hi everyone, a quick follow-up to todays monthly meeting: A couple of months ago I ran into issues getting "flushbottom" typesetting right. See: Today, some of these issues seem to have been fixed. But I still have the impression that vertical glue is still not working completely reliable. Below are a couple of examples. While the second example seems to work ok with \setupalign[height] the last line differs if we have different font size, cf. e.g. page 3 and 4. Best, Denis % From the Wiki : https://wiki.contextgarden.net/Flush_bottom %%%%%% \setupalign[line] \def\Par{bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla} \def\Fig{\placefigure{A figure.}{\framed{\vbox to 5cm{bla}}}} \def\Tab{\placetable{A table.}{\framed{\vbox to 5cm{bla}}}} \starttext \section{Section}\Par\Par\Par\Fig\Par\Par\par\Par\par\Tab \Par\Par\Par\par\Par\Par\par\Par\Par\par\Par\Par\par\Par\Par\Par\Par\Par \section{Section}\Par\Par\Par\Fig\Par\Par\par\Par\par\Tab \Par\Par\Par\par\Par\Par\par\Par\Par\par\Par\Par\par\Par\Par\Par\Par\Par \section{Section}\Par\Par\Par\Fig\Par\Par\par\Par\par\Tab \Par\Par\Par\par\Par\Par\par\Par\Par\par\Par\Par\par\Par\Par\Par\Par\Par \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Another Example %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuppapersize[A5][A5] \showframe \setupalign[line] % \setupalign[height] \setupdelimitedtext[blockquote] [ before={\setupindenting[yes]\tfx\setupinterlinespace}, spacebefore=medium, indentnext=no, leftmargin=no, rightmargin=no, ] \starttext \subject{asdf} \dorecurse{5}{ \input knuth \startblockquote \input ward \stopblockquote \input knuth \input ward \subject{asdf} \input knuth \startblockquote \input ward \stopblockquote \input knuth } \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
