Undefined control sequence: \pdfpxdimen
by Aditya Mahajan 22 Jun '20

22 Jun '20

The drops module uses the primitive \pdfpxdimen in a couple of places, but that is no longer defined in the current beta. What is the equivalent command now? Examples of usage: \pdfpxdimen1in\relax\divide\pdfpxdimen\numexpr\dropsparameter\c! resolution\relax % set actual pixel dimension Aditya

Outputting custom types in MKiv bibliography
by Mike O'Connor 11 Mar '20

11 Mar '20

Hello, I’m trying to create my first publication using ConTeXt mkiv. All going well except for the bibliography formatting. Previously I have used LaTeX, standard entry types in BibTeX, and custom output formats using Biblatex. My publication cites lots of historical sources, viz.: (1) Newspaper articles — currently stored as ‘article’ types in BibTex. (2) Archival sources (historic letter, some leather-bound volume, a catalogued box of old photographs, etc.) — currently stored as ‘unpublished’ or ‘misc'. I would prefer to store these (in BibTeX, buffer, lua, or xml) as custom types (eg. ‘newspaper’, ‘archivalItem’), create setups for how they are output and which fields I output. I found a ’newspaper’ type (and other non-BibTeX types) defined in publ-imp-apa.mkiv as: \startsetups btx:apa:list:newspaper \fastsetup{btx:apa:list:article} \stopsetups I hoped this would mean I could output something: Boxing. (1903, September 13). The Sunday Times, p.8 However, if I create an item of type 'newspaper’ and \cite it I get an output of all stored fields: newspaper: [day: 13] [journal: {The Sunday Times}] [month: 09] [pages:8][title: {Boxing.}] [type: newspaper article] [year: 1903] A similar thing happens if I try to cite the standard BibTeX type ‘misc’. If I store the newspaper item as type ‘article’ I get: “Boxing.”, The Sunday Times, 8, 1903. (missing day and month) Is it relevant that there is a problem when I include \showbtxfields[rotation=30] in my document? The resulting table has ‘*’ for fields in ‘article’, ‘book’, ‘demo-a’, ‘demo-b’ but the columns for ‘newspaper’ and ‘misc’ are empty. Any pointers gratefully received. Cheers, Mike O’Connor P.S. I am working in TeXShop on OSX (10.11.3), and it reports: This is LuaTeX, Version beta-0.80.0 (TeX Live 2015) (rev 5238) ConTeXt ver: 2015.05.18 12:26 MKIV current fmt: 2016.3.19 int: english/english

Cross references to column numbers
by Oliver von Criegern 16 Nov '19

16 Nov '19

Dear list members, how can I create cross references to column numbers? I have a two column layout with column numbers in the header instead of page numbers (actually, these column numbers are calculated from the page numbers). Now I want to create a cross reference that returns the column number of the target. How can I achieve this? Of course, I can get the page number with \pagereference (for the target) and \at (for the reference), but for calculating the column number (according to what I did in the header), I would also need to know whether the target is in the left or in the right column, and I can't see how I can get this information. For an example, see the question posted by me at stackexchange: https://tex.stackexchange.com/questions/502944/context-cross-references-to-… Besides, I am wondering, regarding the generally very regular and consistent naming of commands in ConTeXt, why this is not so in the case of references. For example, to refer to a page, I need \pagereference (for the target) and \at (for the reference); to refer to a line, I need \someline (for the target) and \inline (for the reference), but only if I want it to automatically add the word "line" or something else before the number, otherwise I have to use \inlinerange. It took me some time to find that out. Wouldn't it be easier to have just one command for the target and another one for the reference, and everything else, as counters and headers to be returned, text to be added etc. to be configured by options? Best regards, Oliver.

Hello, here is a minimal sample which doesn't compile: ---- \starttext \startitemize \item A\footnote{% B \startitemize \item C \stopitemize }\crlf D \item E % <<<< This sample compiles when this line is commented (?!) \stopitemize \stoptext ---- The error message is: " ... ...eta/tex/texmf-context/tex/context/base/mkiv/strc-num.lua:465: attempt to index a nil value (local 'd') 2 \startitemize 3 \item 4 A\footnote{% 5 B 6 \startitemize 7 \item C 8 \stopitemize 9 }\crlf 10 D 11 12 >> \item E % <<<< This sample compiles when this line is commented 13 \stopitemize 14 \stoptext 15 " When the "\item E" is commented, the sample compiles successfully. ConTeXt version: "ConTeXt ver: 2019.10.11 15:47 MKIV beta fmt: 2019.10.16 int: english/english". Any idea what's going wrong? Best regards, Lukas

\setuppagenumbering doublesided generates blank pages
by Kerry Sainsbury 30 Oct '19

30 Oct '19

Hi there, I am a newbie, and have *seem* to have discovered that \setuppagenumbering [alternative=doublesided] generates a blank page between chapters. \setupheadertexts[chapter] \setuppagenumbering [alternative=doublesided,location={header,inmargin}] \starttext \startchapter[title={October 2000}] Blah One \stopchapter \startchapter[title={November 2000}] Blah Two \stopchapter \stoptext This produces a PDF in TeXworks containing 4 pages: - Page 1 with a header an 'October 2000' header and 'Blah One' content - Page 2 with a header an 'October 2000' header only. - Page 3 with a header an 'November 2000' header and 'Blah Two' content - Page 4 which is completely blank If I remove the \setuppagenumbering line the PDF contains just two pages, with the expected content. I'm using "ConTeXt ver: 2019.10.11 15:47 MKIV beta fmt: 2019.10.25 int: english/english" Am I doing something wrong, or is this just a bug? Thanks for your help. ConTeXt is making my life *much* easier right now! Kerry

Images run into each other when using side floats
by Marco Patzer 30 Oct '19

Hi! Some images run into each other when using floats. The following example illustrates this. The second image (or frame) runs into the side figure frame. How to prevent this? \setupfloat [figure] [default=left] \starttext \samplefile{knuth} \startplacefigure [title=Foo] \framed [width=5cm, height=5cm]{} \stopplacefigure \samplefile{ward} \blank \framed [width=4cm, height=4cm]{} \samplefile{knuth} \stoptext context 2019.10.29 15:00 Marco

LMTX not hyphenating about contents
by Pablo Rodriguez 30 Oct '19

30 Oct '19

Dear list, using LuaTeX 2.00 20190729 + ConTeXt MkIV 2019.10.28 18:57 with this sample: \starttext \chapter[refer]{amazingchapter} \hsize\zeropoint \about[refer] \stoptext I’m afraid that LMTX doesn’t hyphenate the word, while MkIV hyphenates it fine. Could anyone confirm this issue? Many thanks for your help, Pablo -- http://www.ousia.tk

beta
by Hans Hagen 29 Oct '19

29 Oct '19

Hi, I uploaded a beta. In lmtx there is now a bit more advanced support for svg. A preliminary manual is included that explains a few things. As a teaser ... it is also possible to embed svg code, as in: \startbuffer[svgtest] <svg> <circle cx="50" cy="50" r="40" stroke="green" stroke-width="10" stroke-opacity="0.3" fill="red" fill-opacity="0.3" /> <circle cx="150" cy="50" r="40" stroke="green" stroke-width="10" fill="red" opacity="0.3" /> </svg> \stopbuffer \startTEXpage \includesvgbuffer[svgtest] \stopTEXpage \startTEXpage \includesvgbuffer[svgtest][offset=2bp] \stopTEXpage or in metapost disguise: \startMPpage vardef svg expr c = lmt_svg [ code = c ] enddef ; draw svg "<svg> <circle cx='50' cy='50' r='40' stroke='green' stroke-width='10' stroke-opacity='0.3' fill='red' fill-opacity='0.3' /> <circle cx='150' cy='50' r='40' stroke='green' stroke-width='10' fill='red' opacity='0.3' /> </svg>" ; \stopMPpage It is not a replacement for metapost (which is more efficient runtime anbyway) but for artistic images a mixture might work out ok. In principle inclusion with externalfigure also works when conversion=mps is set but, although I have some 1500 test images, not all might work out well. There can be a lot of crap be hidden in svg files and angle brackets are no guarantee for properly structured images. Especially fonts can be troublesome. On the other hand, if one has very structured input, text labels can be swapped for propertly typeset ones (like math), but that's for later to explain (experimental stuff). We'll see.

Bug in latest LMTX?
by Otared Kavian 29 Oct '19

29 Oct '19

Hi Hans, Last night I updated to th elatest beta LMTX (version 2019.10.28 18:57), and noticed that several things don't work as usual. I have not yet been able to find all the examples, but here is one in math: \definemathfence[abs][bar][command=yes,factor=auto] \starttext \startformula \sup_{t\in {\Bbb R}}\abs{f(t + T) - f(t)} \leq \epsilon. \stopformula \stoptext The above does not typeset and I have the following error message: tex error > tex error on line 7 in file ./bug-math.tex: ! This can't happen (mlist2) \stopforceddisplaymath ->\endgroup \stopimath \strc_math_box_stop ->\stopforceddisplaymath \egroup \d_strc_math_number_wid... \stopdisplaymath ...xpandafter \stopinnermath \fi \afterdisplayspace \egroup \strc_formulas_stop_formula ...formula \endcsname \dostoptagged \dostoptagge... l.7 \stopformula 1 \definemathfence[abs][bar][command=yes,factor=auto] 2 3 \starttext 4 5 \startformula 6 \sup_{t\in {\Bbb R}}\abs{f(t + T) - f(t)} \leq \epsilon. 7 >> \stopformula 8 9 \stoptext I'm broken. Please show this to someone who can fix me. mtx-context | fatal error: return code: 256 Thanks for your attention: OK PS: the PDF produced now with a colorful « error » is very nice… but the error messages are cryptic :-)
