understanding \startTEXpage
by Peter Münster 28 Jan '21

28 Jan '21

Hi, According to https://wiki.contextgarden.net/Command/startTEXpage it "starts a page that fits its contents exactly". But it seems, that part of the content is cropped here: \startTEXpage X \hskip20cm X \stopTEXpage No problem with 10cm instead of 20cm... Is this a bug or expected behaviour? TIA, -- Peter

possible problem with MPinstance or MPinclusions? works in 20200920 but not in the current 20210124 ...
by Rudd, Kevin 26 Jan '21

26 Jan '21

Hi--- I have a number of included figures that work in 20200920 but not in the current 20210124 version. There's a project structure that sets everything up but after that they are input as a figure: \startplacefigure[title={NS Hierarchy}, reference={f:ns-hierarchy}] \input ns_hierarchy \stopplacefigure and generate the error: metafun > log > error: Not implemented: (unknown numeric)=(string) metafun > log > metapost > log > metapost > log > <to be read again> metapost > log > , metapost > log > <*> make_BoxRow [ name = "Parent", metafun > log > metafun > log > I'm afraid I don't know how to apply that operation to that combination of types. Continue, and I'll return the second argument (see above) as the result of theoperation. metafun > log > metapost > log > label = "Parent Root Namespace", ]; ; >From triaging, it looks like the "boxrow.mp" file isn't being input by the current version from within the MPinclusions block associated with the MPinstance; the error appears to be spurious as a result of make_BoxRow not being defined and doesn't occur in the old version where the file is input. "boxrow.mp" is not in the same directory as the document but is in the configured through the usepath/usesubpath interface from an environment file. I can put together and share a runnable MWE set of files if this information is not complete enough to identify the problem. Here is the MWE that I used for the input figure file that demonstrates the problem. \defineMPinstance[ns_hier] [ format=metafun, extensions=yes, initializations=yes, method=double, ] \startMPinclusions{ns_hier} input boxrow \stopMPinclusions \startMPdefinitions{ns_hier} % nothing to see here.... \stopMPdefinitions \startMPcode{ns_hier} make_BoxRow [ name = "Parent", label = "Parent Root Namespace", ]; \stopMPcode Thanks for any feedback, ---K Kevin W.

I just realized that \starbreak was one of my own macros (defined ages ago) so the MWE should be: \usemodule[fancybreak] \define\starbreak{ \fancybreak{ \strut\hfill\hfill\symbol[star]\hfill\symbol[star]\hfill\symbol[star]\hfill\ hfill\strut }} \starttext \input ward \starbreak \input ward \stoptext Sorry for the confusion.

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

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

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
