Inline Fractions
by Johann Birnick 25 Jan '21

25 Jan '21

Recently inline fractions stopped working correctly. For example symbol spacing, sub-/superscripts, the line is too short,... You can see the 3 named problems and how they sometimes appear and sometimes not in this two fractions: \starttext $\frac{\sin(x)}{16 \pi \epsilon_0 c^2 m_e^2} \frac{\sin(x)}{\epsilon_0}$ \stoptext Compare the output between the current LMTX version with some old version. (I compared with mk4, because I had nothing else available. I don't know when bugs were introduced.) Best regards, Johann

fancybreak module
by Clyde Johnston 25 Jan '21

25 Jan '21

I have finally gotten around to upgrading my ConTeXt installation to LTMX and found that the \starbreak command in the "fancybreak" module no longer works. \usemodule[fancybreak] \starttext \input ward \starbreak \input ward \stoptext Have I missed something about the LTMX changes? I was working in version 2018.07.02 14:39 but not in 2021.01.24 16:07. Regards, Clyde

Re: [NTG-context] Missing images in Wiki?
by Andres Conrado Montoya Acosta 25 Jan '21

This is one example: https://wiki.contextgarden.net/Command/externalfigure However, now I checked the source, and the image files are there... and they are being correctly linked, but the image attributes width and height are set to zero. Maybe something wrong with lazy loading? Example in html code: <img class="image-lazy-loaded" alt="" style="" src="/wikiteximage/966d36e3a607022bcbae59654239a147.png" srcset="" *width="0" height="0"*> El vie, 22 ene 2021 a las 6:00, <ntg-context-request(a)ntg.nl> escribió: > Send ntg-context mailing list submissions to > ntg-context(a)ntg.nl > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.ntg.nl/mailman/listinfo/ntg-context > or, via email, send a message with subject or body 'help' to > ntg-context-request(a)ntg.nl > > You can reach the person managing the list at > ntg-context-owner(a)ntg.nl > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of ntg-context digest..." > > > Today's Topics: > > 1.

Using \overloaded
by Rik Kabel 24 Jan '21

24 Jan '21

Hans and all, Preparing my standard environments for future strict enforcement of overloading prevention, I have run into one issue. I had been using the following construction to change the formatting of URLs: \let\OrigHyphenatedurl\hyphenatedurl \starttexdefinition hyphenatedurl #URL \begingroup \URLfont\OrigHyphenatedurl{#URL} \endgroup \stoptexdefinition This results in the following warning about overloading \hyphenatedurl: csname overload > warning, protection level 3, control sequence 'hyphenatedurl', properties 'permanent protected', file 'env_layout.mkvi', line 1 I have tried adding \overloaded to indicate the intentional overloading, but \overloaded cannot be used with \starttexdefinition, so I rewrote it as: \let\OrigHyphenatedurl\hyphenatedurl \overloaded\define[1]\hyphenatedurl{% \begingroup% \URLfont\OrigHyphenatedurl{#1}% \endgroup}% but that (and also with \overloaded\def\hyphenatedurl#1...) gives the same (except for the line number) warning: csname overload > warning, protection level 3, control sequence 'hyphenatedurl', properties 'permanent protected', file 'env_layout.mkvi', line 822 So, what is the proper way to indicate intentional overloading? Or should this redefinition be done in another way? (Also, it is interesting that the line number in the first warning message does not point to the actual line.) -- Rik

Buggy pdf viewer? Many thanks for your reply, Hans. Images are found, but not with "directory=default", but with "location=default". Evince doesn’t display the images or colors. Acrobat for Linux doesn’t display it either (this is why I thought it might be a bug). But MuPDF and SumtraPDF (based on MuPDF) display it fine. Sorry for the noise and many thanks for your help, Pablo -- http://www.ousia.tk

\doassign variable - updates not picked up
by Werner Hennrich 23 Jan '21

23 Jan '21

Hello everyone, I'm using ConTeXt (ver: 2020.09.20 23:02 LMTX) and have to have conditional page headers based on specific content criteria. To achive this I'd like to get some global variables in TeX, change their values several times throughout the document and have my macro for the header read them and act accordingly (like skip the header at all, change a color, etc). As a basis for this I established the following pattern in an iolated test case: \def\setHeaderVar[#1]{ \doassign[header][myvar=#1] \message{setHEADER: '#1'} } \def\getHeaderVar{\headermyvar} \setupheadertexts[\setups{page:header}] \startsetups page:header HEADER: myvar=\getHeaderVar \stopsetups \starttext \setHeaderVar[initval] page: 1 \page \setHeaderVar[aaaaa] page: 2 \page \setHeaderVar[bbbbb] page: 3 \page \setHeaderVar[cccc] page: 4 \page \setHeaderVar[] page: 5 \stoptext This works as expected and the header-macro prints the updated value. But when I put the same pattern in my big environment-file, I can see the variable being updated with different values (console), but the header always puts out just the variable's initial value - so the variable is read but it's updates aren't picked up by the header macro. Peeking into console, log & tuc didn't raise any idea yet as to what is going wrong... Any idea what is happening and how I can fix this? Any hints on how I can track this down? Thanks a lot, Werner Hennrich, Vienna AT
