underbrace spacing
by Johann Birnick 01 Jan '21

01 Jan '21

Hi there, if I do \starttext $4 \underbrace{+ 3}_{\text{because of lorem} + 2}$ \stoptext then the spacing gets really big because of the long. How can I prevent this? (in LaTeX one can use \mathcal or so and that works) Best regards, Johann

prevent error page
by Johann Birnick 01 Jan '21

01 Jan '21

Hi there, in my setup I constantly have a pdf viewer open showing the output of context. When I recompile the viewer updates. Now if there is an error, the document fails to compile, of course. Previously the pdf file just remainded untouched, nice. But now with LMTX, the pdf will be overwritten with a pdf just saying "error". This makes my pdf viewer crash! I can't work like this. So how to prevent this "error" page and just let context remain the pdf untouched if there is an error? Best regards, Johann

\startblockquote…\stopblockquote issue
by Alan Bowen 31 Dec '20

31 Dec '20

In the latest standalone ( ConTeXt ver: 2020.12.30 16:45 LMTX fmt: 2020.12.30), \startblockquote and \stopblockquote do not work when I use the key, method=font, or include \setupquotation[method=font]. MWE %\setupquotation[method=font] \setupdelimitedtext[blockquote][ % method=font, before={\blank[small,fixed] \setupnarrower[left=1.5pc,right=0pc] \startnarrower[left,right] \noindentation\switchtobodyfont[9pt]}, after={\par\stopnarrower \blank[small,fixed] \noindentation},] \starttext \input ward \startblockquote \input ward \stopblockquote \stoptext I am attempting to get protrusion of the left double quotation mark into the left margin when possible at the start of a line and do not understand why my block quotations are not appearing as expected.

lmtx: new text & math font stuff
by Hans Hagen 30 Dec '20

30 Dec '20

Hi, As you know, lmtx is also a place for experiments. Currently I'm playing a bit with fonts. Recently (as mentioned a whil eback) I added glyph scaling which permits interesting trickery, although one needs to be aware of how it combines with other features. Here's an example: \def\UnKernedTeX {T% {\glyph xoffset -.2ex yoffset -.4ex `E}% {\glyph xoffset -.4ex options "C0 `X}} \dorecurse{100}{ x \UnKernedTeX} There are alse \glyphxscale cum suis but again, beware that it might influence things when not used grouped. At some point this will be an option in scaled fonts (think of \tfc and such). It saves instances. You can get an idea with: \enableexperiments[text.fonts.compact] The 'text' in this command suggests that we can also do that with math and indeed we have \enableexperiments[math.fonts.compact] These directives have to come *before* loading fonts in order to be effective. Especially the math can bring down the number of font instances: text, script and scriptscript all use the same instance, which is good news. The bad news is that it's up to users to check how this plays out. There are some differences due to the fact that scaling happens elsewhere and otherwise which results in tiny differences (4/5th decimal). As said, these are experiments so ity might progress. I post intermediate versions because that way I can control it better. There is another variant in the planning. Yet another expriment (undecided if that will stay, i played with if before and then rejected it): \enabledirectives[fonts.injections.method=advance] If it stays I probbably have to patch some other code to better suit it. Overall, although in math it add to the overhead, due to the fact that math is hardly demanding (makes only a fraction of the rendering) the memory footprint can be quite a bit lower and performance a bit better (not that much). The measures used in rendering are kind of floating (recalculated often) when these mechanisms are enabled but my impression is that todays compilers make that hardly noticeable. As usual, it opens up possibilities, but of course at the price of testing.

Protruding quotation marks obviate narrowed quotations
by Michael Guravage 30 Dec '20

30 Dec '20

Several months ago I posed the following question. When I start a paragraph with a \quote or a \quotation the left quotemark does not protrude, but when I use Unicode quotes it does. I would prefer to use the commands. Any suggestions on how I can achieve proper left protrusion without resorting to Unicode characters? Wolfgang suggested the following lines of code; which worked perfically. \setupquotation [method=font] \setupquote [method=font] Returning to this project after several months I observe that when I use a \start- stopquotation environment, the quotation is not narrowed. The \setupquotation command obviously affects both the \quotation command and \start- stopquotation environment. Is there an elegant way to apply the \setupquotation command and retain the quotation indentation? Cheers, Michael Here's a mwe. \showframe \showgrid \setupwhitespace[medium] % Setup hanging punctuation, less severe style \definefontfeature [default] [default] [protrusion=punctuation,expansion=quality] \setupalign[hz,hanging] % Provide protrusion for quotations. \setupquotation[method=font] % Toggle this line to see the effect. \setupquote[method=font] \starttext \startparagraph \quotation[method=font]{Love makes the world go round,} as an old proverb has it\ldots \stopparagraph \startquotation \input tufte \stopquotation \stoptext

Title in enumeration not working?
by Mikael Sundqvist 30 Dec '20

Hi, Has anything changed with titles and enumerations? I expected a title "Title" with the following setup. \defineenumeration[example][ text=Example, title=yes, ] \starttext \startexample[title={Title}] This is a test. \stopexample \stoptext But it does not show up. /Mikael

text alignment issue
by Alan Bowen 30 Dec '20

30 Dec '20

In the last few versions of luametatex standalone, paragraphs that were once justified now appear ragged right. My insertions of \setupparagraphs[align=wide/normal/yes] and \setupalign[wide/normal/yes] have had no effect. Is there some new coding that is needed to get justified text? Alan

Dear Pablo, Thank you for your reply. I just search wiki not the mailing list. I never used \setupnote before. > I would say that LMTX is causing an issue here (but for sure Hans knows > better). > > The issue with your MWE is solved by adding: > > \setupnote[footnote][width=\textwidth] It works fine. Thanks again. Best regards, Dalyoung
