align text and formula
by Jan Willem Flamma 09 Feb '17

09 Feb '17

Dear list, I would like to include text on the same line as a formula. The text needs to be left-aligned and the formula needs to be mid-aligned (as per normal). I’ve tried various solutions from the mathalign MyWay but have not succeeded to get the desired result sofar. Below a M-Not-WE. Clearly, the formula is not positioned correctly yet. Who can help me out? Regards, Jan Willem \starttext \setupformulas[align=flushleft] \startformula \startalign[n=2,align={left,middle}] \NC \text{Text1} \NC E = mc^2 \NR \NC \text{Text2} \NC E = mc^2 \NR \stopalign \stopformula \stoptext

Back on grid after displayed math
by Mikael P. Sundqvist 26 Dec '16

26 Dec '16

Hi! Im curious how to get back to the grid after a displayed formula? I try \setuplayout[grid=yes] \showgrid \setupformulas[align=middle] \starttext \input knuth \startformula a^2+b^2=c^2 \stopformula \input knuth \stoptext (where the \setupformulas[align=middle] was suggested in a comment at http://tex.stackexchange.com/questions/254815/grid-on-aligned-equations-in-… , but that makes no difference) but that does not work (result attached). Would it be easier if there were also an option saying how many lines the equation should take? Say, \startformula[lines=3] a^2+b^2=c^2 \stopformula and then centering the formula (or having options for that) vertically over the three lines? Maybe that is a not a good idea for some reason... /Mikael

Footnotes in footnotes

16 Oct '16

Dear list, I want to report a possible bug (I think), when one try to put a footnote into another footnote, here is MWE (from wiki): \starttext This\footnote{Or that\footnote{Or possibly even the other.}, if you prefer.} is a sentence with a footnote. \stoptext As you can see, the second footnote is not placed in the page. Thanks.

MKIV caption separator, revisited
by Rik Kabel 10 Oct '16

10 Oct '16

Has any progress been made in the past few years implementing modifiable separators for captions under MKIV? This was raised as an issue by (at least) Mojca Miklavec in December 2010 (http://www.mail-archive.com/ntg-context%40ntg.nl/msg51542.html) and by Andy Thomas 18 months later (http://www.mail-archive.com/ntg-context%40ntg.nl/msg63937.html) (Their issues with stopper have been resolved. In MKIV it is numberstopper.) Here is an MWE demonstrating the problem. It compiles cleanly, but the separator remains the default period. With MKII, it generates a figure with a hyphen and not a period. \setupcaptions[separator=-] \setupexternalfigures[location=default] \starttext \chapter{Chaptername} \section{Sectionname} \placefigure[here][fig:1]{Caption}{\externalfigure[cow.pdf]} \in{See Figure}{.}[fig:1] \stoptext -- Rik Kabel

Last version standalone ConTeXt issue.
by Jaroslav Hajtmar 10 Oct '16

10 Oct '16

Hello ConTeXist. In the latest version ConTeXt it stopped working my macros which contents function he once advised me Taco. It is low level lua code. Can anyone advise me what the problem is, eventually. how to replace Lua code in my function to make it work again? Macros worked at least 6 years and now crashes. Here is my function: function thirddata.handlecsv.texmacroisdefined(macroname) -- check whether macroname macro is defined in ConTeXt -- function is used to test whether the user has defined the macro \macroname. If not, it needs to define any default value if token.csname_name(token.create(macroname)) == macroname then return true else return false end end Is there any alternative (ConTeXt like), which is should be possible use in Lua code? Thanx Jaroslav Hajtmar

Overfull boxes in bibliography
by Henri Menke 28 Sep '16

28 Sep '16

Dear list, I noticed, that even though I set \version[temporary] to make overfull boxes visible, they were not marked with an overfullrule in the bibliography. Below you find a minimal example which reproduces the problem on TL 2016. First I typeset the entry by hand where the black rectangle shows up in the margin, then I format it automatically using \placelistofpublications where no box is shown. How can I have overfull boxes highlighted in the bibliography? Many thanks, Henri --- \startbuffer[biblio] @article{Heisenberg1926, author = {Heisenberg, W.}, title = {Mehrk\"orperproblem und Resonanz in der Quantenmechanik}, journal = {Zeitschrift f\"ur Physik}, year = {1926}, volume = {38}, number = {6}, pages = {411--426}, issn = {0044-3328}, doi = {10.1007/BF01397160}, url = {http://dx.doi.org/10.1007/BF01397160} } \stopbuffer \version[temporary] \setuppapersize[A5][A5] \usebtxdataset[biblio.buffer] \usebtxdefinitions[aps] \starttext \showframe \setupitemize[left={[},right={]},width=3em,stopper=] \startitemize[n] \item W.

For the Mac users: AppleScript to launch ConTeXt in a flexile way
by Thomas Floeren 22 Sep '16

22 Sep '16

Hello, Some months ago I wrote a little AppleScript script with one purpose: It should be a flexible script to launch ConTeXt typesetting, independently of the text editor I’m using and it should be capable to typeset the Product file even if I’m currently editing any component file belonging to that Product file. I used it for some time, I improved it, and I shared it with a collegue who also works with ConText on OSX. We’re still using it, many bugs have been fixed and some features were added. The script proved to be very useful for us and I thought, why not share it with the other Mac-ConTeXt people? So here it is: https://www.wuala.com/tflo/Scripts/Ctx%20Typeset/?key=75QkpizhdpFS As already said, the main purpose of the script is to launch the Ctx typesetting process (short: Ctx) on a file. Regarding the “a file” the script is very configurable and flexible: A) It can launch Ctx on a file currently opened in your text editor. It works with many text editors (BBEdit, MacVim, TextMate, etc.) as long as the editor is the frontmost process. B) It can launch Ctx on the parent Product file of the component file currently being edited. Defining a “Product file” can either be done semi-automatically or by hard-definition with two swappable register slots. C) If no eligible file is opend in an editor it will launch Ctx on the currently selected tex file in the Finder. The options added in the course of time are: A) Usage of a ConTeXt-Beta or a ConTeXt-Current installation, swappable B) Typesetting in the non-interactive shell or in the visible terminal C) Notifications D) Selection of PDF viewer (Skim, Preview, Adobe, …) E) Automatically calling the PDF viewer or not F) Optionally excluding generated PDFs from TM backup G) luatex or luajitex H) Beeps or no beeps, and so on I) Many other things, explained in the Description Also some features (“Tools”) have been added: A) Purging files including generated PDFs B) Info on the used Ctx version C) Updating the Ctx Minimal (Beta or/and Current) and archiving the old one D) Syntax Check E) Make formats, listing fonts, other, … F) Some extras added in the Extras folder (synctex with BBEdit etc.) G) Much more in the Description Some caveats: A) It works only on OS X B) The script is designed to work with 10.9 (Mavericks). It should also work with 10.8 (old notification via 3rdParty is still implemented). C) Out of the box it works only with the so called “ConTeXt Minimal Installation” (aka ConTeXt Standalone). It won’t work with TeXLive installations or any other kind of excessively screwed-up installations. But you can go into the script to make it work with anything. D) In order to get access to any text editor the script makes use of GUI scripting: you have to liberate the rights in the corresponding OS preferences. This may sound risky to you but the code is open so you can assure yourself of what the script does. E) You have to (and you really should!) read the Description that comes with the script. If you are enjoing the script please share it here, if the script is buggy, or doesn’t work for you at all please let me know too, please. Thank you best wishes -- Thomas

Perhaps missing braces in buff-ini.mkiv?
by Henri Menke 06 Sep '16

06 Sep '16

Dear list, it seems as if there are braces missing in the definition of \buff_save around #2. \def\buff_save[#1][#2]% {... {\setupcurrentsavebuffer[\c!list={#1},\c!file=#2]}% ...} I think they are missing, because it makes the following work, even though arguments and key-value arguments shouldn't be mixed up. \startbuffer[hash] foo \stopbuffer \savebuffer[hash][hello.txt,prefix=no] \starttext \stoptext I think you should either make a third argument for a key-value list or just make the second argument the key-value list. Then users could input \savebuffer[hash][file=hello.txt,prefix=no]. Cheers, Henri
