\completecontent affects text height
by Thangalin 19 Feb '14

19 Feb '14

Hi, First question: 1. Save http://pastebin.com/raw.php?i=8DQNCcvC as setup.tex 2. Save http://pastebin.com/raw.php?i=KgcxCxGB as garlic.tex 3. Run: context garlic.tex 4. View page 3 of the PDF ( http://i.imgur.com/VLwssnl.png ) 5. Edit garlic.tex. 6. Remove \completecontent 7. Run: context garlic.tex 8. View page 3 of the PDF ( http://i.imgur.com/HVAoavQ.png ) The Table of Contents affects the column height in the body. The available height for the text body should be independent of \completecontent. The total height should be as shown in the second example, with or without the ToC. How can this be resolved? Second question: How would you remove the white space above each subsection title so that the title is aligned to the top of its column? Third question: How would you prevent widowing of subsection titles from their content? I tried "ntop=2" and "\setuptolerance[tolerant]", but neither affected the result. Thank you!

(If I had them at hand I would try.) Thank you Martin. I was not clear. I can run Debian and other *nix flavors on the chromebook by various methods and then have ConTeXt, but I would rather not 'dual boot.' What I am after is to have ConTeXt run 'natively,' if that is the right word/concept, on a chromebook core platform. From the chromebook shell I know I can run vim to edit files but I would like to compile them. (Viewing will be the next chapter!)

[Math in ConTeXt]
by Otared Kavian 18 Feb '14

18 Feb '14

Hi all, After a series of exchanges on the list, on the topic of how mathematics typesetting is and should be in ConTeXt, I am writing you this message to ask all those who use ConTeXt to typeset mathematics and who encounter various types of difficulties, or shortcomings, to send me their remarks, either on list or off list. I will check the problems with Aditya Mahajan and Mikael Sundqvist, and then submit feature requests or bug reports to Hans and Aditya who will try to fix the issues (I have asked these people about this, and they all agree…). In order to help me manage efficiently the task, please add the following tag [Math on ConTeXt] to the Subject field of your message. The issues which may be addressed are of the following categories: 1. Differences in the output of ConTeXt mkiv vs mkii (due to differences in engine) 2. Differences in the output of ConTeXt mkiv vs LuaLaTeX + Opentype math fonts (due to differences in macro package) 3. Differences in the output of ConTeXt mkiv vs PDFLaTeX + AMSMath (due to differences in expectation) 4. Bug reports (regarding commands of plain TeX missing in ConTeXt, the position of math accents, etc…) Indeed some of the issues may have their origin in the fonts (therefore not easy to fix thouroughly), but others may be fixed once the expectations are clearly expressed. As usual, please give minimal examples imbedded in \starttext ……… \stoptext so that we can test the issue you are reporting. Thanks for your attention and cooperation, Best regards: OK

Hi list, I'd like to have a figure (by means of \placefigure) centered horizontally. Currently, I'm doing \placefigure[bottom,none,middle]{}{% \hbox to\textwidth{\hfil\externalfigure[logo-2-t][height=1.5cm]\hfil}} Is there a better way? If yes, how to do this?

1. \setupbackgrounds with colours 2. \textwidth = 1.09\textwidth?
by Rudolf Bahr 17 Feb '14

17 Feb '14

Hello listmembers, 1. With "\setupbackgrounds" finally I achieved what I intended (see pdf-file), according to Context reference manual p. 187. But a question remains: Is it a feature of context not to colourize header and footer alone, but only in conjunction with text? 2. In the appended pdf-file it is also to be seen, that the horizontal \hrule strokes are wider than \textwidth, i.e. they begin in leftmargin and extend to within rightmargin, whereas the vertical \vrule strokes exactly are as high as expected. Is there a bug in my program?

Indenting after floating image
by Jan Tosovsky 17 Feb '14

17 Feb '14

Dear All, when an indenting is set, it is applied in a smart way and sometimes suppressed, e.g after images. But when the image is floating and forced to be displayed on a separate page, I would expect the indenting of the following paragraph preserved. Currently it doesn't, see this example: \setupexternalfigures[location=default] \setupindenting[medium, yes] \starttext \input{ward} \startplacefigure[number=no, location={page}, title={}] \externalfigure[cow] \stopplacefigure \input{ward} \stoptext Is there a global switch for it or am I to force the indenting in these cases manually? Thanks, Jan

ConTeXt minimal on chromebook
by John Kitzmiller 17 Feb '14

17 Feb '14

I attempted to put ConTeXt minimal on Samsung chromebook and got: Error: your system "Linux armv7l" is not supported yet. Please report to the ConTeXt mailing-list (ntg-context(a)ntg.nl) This is not a request to support the armv7l (unless it is trivial) but, is it futile to attempt installing minimal on a chromebook with Intel ATOM N570, or Intel Celeron-867?

wrong \sc i with Palatino Linotype

Dear list, I have noticed that ConTeXt (beta from 2014.02.14 17:07) has a problem with Palatino Linotype.

Pgfplots - passing point coordinates by Lua
by Lukáš Procházka 17 Feb '14

17 Feb '14

Hello, I just started experimenting with pgfplots package. I'd have two questions: 1) When plotting/loading a data file: Is it possible to specify the comment mark, which is '#' and '%" by default? I'd need to treat ';' as a comment mark, too. 2) How to pass coordinates of plot points by Lua? The following code: ---- \usemodule[tikz] \usemodule[pgfplots] \startluacode data = {{5, 15}, {20, 20}, {24, -24}} plot = function(data) local str for i, v in ipairs(data) do str = (str or "") .. "(" .. v[1] .. "," .. v[2] .. ")" end print("Crds=", str) context(str) end \stopluacode \starttext \starttikzpicture \startaxis[] \addplot[mark=none,color=red] coordinates {(11, 5) (12, 18)}; % THIS PLOT IS OK \addplot[mark=none,color=red] coordinates {\ctxlua{plot(data)}}; % THIS PLOT HAS NO POINT (?!) \stopaxis \stoptikzpicture \stoptext ---- gives error: " ... fonts > fallback modern rm 12pt is loaded Crds= (5,15)(20,20)(24,-24) Package pgfplots: Error! Sorry, I could not read the plot coordinates near '(5,15)(20,20)(24,-24)'. Please check for format mistakes. !

A default editor for ConTeXt standalone?
by Marcin Borkowski 16 Feb '14

16 Feb '14

Hi all, just a thought. Some time ago wise people decided to include TeXworks into TeXlive, so that newbies installing TeXlive can get a "batteries-included" package (not having to choose/install an editor). Would it be (a) reasonable and (b) not too much time-consuming to do a similar move with ConTeXt standalone? I'm not saying it would have to be TeXworks (or my beloved Emacs, for that matter;)). I am aware that this is an additional work to maintain etc., and I'm probably not capable of doing it myself, but... What do you think? -- Marcin Borkowski http://octd.wmi.amu.edu.pl/en/Marcin_Borkowski Adam Mickiewicz University

writetolist doesn't include sectionnumber in mkiv?
by Sanjoy Mahajan 15 Feb '14

15 Feb '14

With MkIV, I'm having trouble getting \writetolist to include sectionnumbers. Or at least, I cannot get the typeset list to include the sectionnumbers (but maybe writetolist sent in the information). Here's a minimal example, which is almost exactly the example from the wiki at <http://wiki.contextgarden.net/Command/setuplist>. The only change is that I've included [order=command] so that the \hrule ends up at the right place. \definelist[Reprints][criterium=all] \starttext \section{Sec 1} \writetolist[Reprints]{1.}{List entry A} \subsection{Subsec 1} \writebetweenlist[Reprints]{\hrule} \writetolist[Reprints]{2.}{List entry B} \completelist[Reprints][order=command] \stoptext When typeset (I'm using the 2014.02.14 beta), the completelist looks like: List entry A 1 -------------------- List entry B 1 But the 1. and 2. didn't show up in the left column. I tried adding \setuplist[Reprints][sectionnumber=yes] but that didn't help. Does one need to define an alternative that includes sectionnumbers? -Sanjoy

underbraces slightly too narrow (with MkIV 2013.05.28)
by Sanjoy Mahajan 15 Feb '14

15 Feb '14

In certain cases, display-mathunderbraces are not quite wide enough. Here's a minimal example: =================== \starttext \placeformula\startformula \underbrace{15\,\tf cm}_{L} \stopformula \stoptext =================== Using 2013.05.28 00:36 MKIV (from vanilla TL2013), the left brace tip starts under the vertical bar of the "1", instead of enclosing the serif as well. The right brace tip ends between the last two tines of the "m", instead of enclosing the whole "m" and its serifs. With 2013.04.09 10:38 MKII, the brace tips extend just slightly beyond the "15 cm", which is better. However, they seem slightly too close. As a test, I ran the comparable plain-TeX file through LuaTeX and PDFTeX. ================== $$ \underbrace{15\,\rm cm}_{L} $$ \bye ================== The gap between the right brace tip and the text is slightly greater (with either LuaTeX or PDFTeX), and it looks right. (With the 2012.05.30 MKIV on live.contextgarden.net, the result is similar to the Lua/PDFTeX versions, though not identical, and also looks reasonable.) -Sanjoy

missing underbrace using palatino with latest beta (2013.12.26)

A minimal example: ----------- cut --------------- \setupbodyfont[palatino,12pt] \starttext \startformula \underbrace{x}_{1} \stopformula \stoptext ----------- cut --------------- It works fine with 2013.05.28 00:36 MKIV current. With 2013.12.26 12:50 MKIV beta, the underbrace disappears. With a bigger target (e.g. "xyz" instead of "x") or with the default font, the underbrace returns. -- -Sanjoy

bug in page break and footnotes
by Pablo Rodriguez 14 Feb '14

14 Feb '14

Dear list, I have just discovered that there is a buggy interaction between references and footnotes. The sample is taken form a book I’m writing. When including two \about and a footnote at the end of the paragraph, ConTeXt is not able to move the two last lines from paragraph to the next page (http://www.ousia.tk/wrong-break.pdf) But the weird thing is that both the footnote and the text from the second \about to the end of the line are placed at the bottom of the page. If I remove any of the two \about, text is not misplaced, but footnote reference and point are (http://www.ousia.tk/wrong-footnote.pdf) And if I remove both \about or replace them with \at or \in, everything works as expected (http://www.ousia.tk/right-break.pdf) Sorry, but I’m afraid I cannot provide a code sample that reproduces the bug. I tried it and it worked fine. And I have no idea of what might trigger the bug. BTW, I’m using beta from 2014.02.01 14:22. AFAIK, this is the latest one. And this is also broken with the stable version (2014.01.03 00:40). Many thanks for your help, Pablo -- http://www.ousia.tk

narrowered columns on background image?
