How to put title and counter of the enumeration env. in the FrameTitle?
by Jeong Dal 03 Dec '15

03 Dec '15

Hi, I use the FunnyFrame and FrameTitle in the metafun book to display theorems. Thanks ConTeXt and MetaFun, it looks nice! For better output, I try to put “Theorem + number” in the FrameTitle instead of putting in the main text. But I couldn’t make it. I found a similar question and answers by Hans in the list (2015. 8.6-7) under the title “Some questions about an environment (Metafun)” It works fine but I want to put number too. I think that I want to much. Thanks for reading. Best regards, Dalyoung I am using the following code. %%%%%%%%%%%% \defineenumeration[Theorem] [%text=Theorem , style=, % title=yes, prefix=yes, prefixsegments=chapter, way=bychapter, number=yes, before={\blank[big]}, after=\blank] \defineenumeration[Definition] [text=Definition, style=, % title=yes, prefix=yes, prefixsegments=chapter, way=bychapter, number=yes, before={\blank[big]}, after=\blank] \startuseMPgraphic{FunnyFrame} picture p ; numeric o ; path a, b ; pair c ; p := textext.rt(\MPstring{FunnyFrame}) ; o := BodyFontSize ; a := unitsquare xyscaled (OverlayWidth,OverlayHeight) ; p := p shifted (2o,OverlayHeight-ypart center p) ; drawoptions (withpen pencircle scaled 1pt withcolor .625red) ; b := a superellipsed .95 ; %fill b withcolor .85white ; draw b ; b := (boundingbox p) superellipsed .95 ; fill b withcolor .425green;%.85white ; draw b ; draw p withcolor black ; setbounds currentpicture to a ; \stopuseMPgraphic \defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}] \defineframedtext[FunnyText][frame=off,background=FunnyFrame, offset=\bodyfontsize, width=\textwidth]%\overlaywidth]% \def\StTheorem{\startFunnyText\startTheorem} \def\SpTheorem {\stopTheorem\stopFunnyText } \def\FrameTitle#1% {\setMPtext{FunnyFrame}{\hbox spread 1em{\hss\strut\ss\bf\white #1\hss}}} \starttext This is a test for Framed Theorem. \StTheorem This is a theorem in the Funny Frame. \SpTheorem I'd like to put \quote{Theorem \#1(Some Title)} in a small frame and the main text in the big frame. \blank[big] {\FrameTitle{Theorem 2(Title of Theorem)} \StTheorem I want to show the main text without \quote{Theorem 2} in this frame. \SpTheorem \stoptext %%%%%%%%%%%%%%%%%%

Fill up "bottom" space of page with some content
by josephcanedo＠gmail.com 03 Dec '15

03 Dec '15

Hi Thangalin, Thanks a lot for replying, Sure, I attach 2 mwe’s. First one (fill_mwe.tex) shows a “lettrine” + paragraph cut in bottom of 1st page (not desirable). To fix this problem I add \setpenalties\clubpenalties{5}{10000} to make sure the 6 first lines of paragraph are all together (5 lines for lettrine + 1 line to cover down the “lettrine”). This is shown in fill2_mwe.tex. There is another problem if the paragraph is too short (less than 5-6 lines) as the next paragraph will overlap with the figure, but that’s another story. Now of course, in the bottom of the page 1 there is a large space and I would like to insert some decorative item. But my problem is that I do not know how to write some logic to insert this decorative stuff only if the title of Section 2 is moved to second page (if it is not, ie the section 1 is shorter, the section 2 title and beginning would follow in page 1). I was hoping there was a possibility to have some “filling” function that’s called if the page has still some space (I remember there is a setting called \setuplayout[line] that arranges to do this with the lines in the page.) Hope this clarifies a bit, Best regards Joseph From: Thangalin Sent: ‎Thursday‎, ‎December‎ ‎3‎, ‎2015 ‎9‎:‎27‎ ‎PM To: ntg-context(a)ntg.nl Hi Joseph, Mind posting a minimum working example to illustrate what you're trying to accomplish? ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context(a)ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________

Fill up "bottom" space of page with some content
by josephcanedo＠gmail.com 03 Dec '15

03 Dec '15

Dear all, I wondered if there was a way to fill up the bottom of the page with some content (an image, some decorative pattern …) to avoid large blank space in page (given some limits, ie more than 2 lines of space is left blank). By bottom of page I mean remaining space that could have been filled with text but given there was a page break it’s left blank. I saw some similar posts (relative to Fleuron) but the difficulty is that the amount of remaining space in the page is not easy to calculate, for example when having graphics, large drop caps that trigger a page break. Hoping my question is clear enough. Thanks for any hint Best regards Joseph Canedo

Reconciling unicode-math with LaTeX2e mathematics

In math mode, using LaTeX, math fonts can use only math spacing: $abc ffi$ gives abcffi. ($abc ffi$ is equivalent to $\symit{abc ffi}$—\symxx commands were introduced in the 2015 update of the unicode-math package by Will Robertson, allowing upright, slanted, bold, etc. math fonts with \symup, \symsl \symbf, etc., respectively.) However, in math mode, using ConTeXt, text fonts can use only TEXT spacing (no MATH spacing commands): $\text{\it abc ffi}$ gives abc ffi. So this is the FEATURE that needs to be added. I suggest that you implement a new set of commands called \textxx for this (text fonts with MATH spacing in math mode—please see the enclosed P.D.F. file). As far as math fonts are concerned using ConTeXt in math mode, it's okay: $\it{abc ffi}$ gives abcffi. But you should note that in the source of ConTeXt you (Hans) introduced \mathit (and \mathup & \mathtf, \mathsl, \mathbf, etc.) as an equivalent of \it (\tf, \sl, \bf, etc., respectively) for "A.M.S. LaTeX compatibility", though in A.M.S. LaTeX the \mathxx commands are not MATH fonts but TEXT fonts with math spacing (as pointed out by Will Robertson in the very first seconds from 41 min 40 s of his talk in the link above) so it not compatible (but that's fine since the name \mathxx in A.M.S. LaTeX was not very well chosen in the first place but thereafter kept for backward compatibility, so that in ConTeXt we can keep it used for MATH fonts instead and introduce \textxx for TEXT fonts with math spacing, as suggested in the previous paragraph). Please see the enclosed P.D.F. file that sums everything up to understand visually what I mean with the missing feature I request (adding new \textxx commands for text fonts with MATH spacing in math mode), and let me know what you think.

natural tables and columndistance/spaceinbetween
by Alan BRASLAU 02 Dec '15

02 Dec '15

In natural tables http://wiki.contextgarden.net/TABLE the parameters columndistance=dimension, and spaceinbetween=dimension, will set the gaps between columns and rows, respectively. Is there some way of specifying row gaps for specific rows? For example, say that I only want a gap after the first row. I tried: \bTABLE \bTR [spaceinbetween=.25em] \bTD 1 \eTD \bTD 2 \eTD \eTR \bTR \bTD A \eTD \bTD B \eTD \eTR \bTR \bTD a \eTD \bTD b \eTD \eTR \eTABLE Alternately, I tried \setupTABLE [r][1][spaceinbetween=.25em] but these do not work. One might think about trying \bTR [bottomframe=on,framecolor=white,rulethickness=.25em] ... \eTR but this presents several problems: 1) When using background=color, the background color gives a hairline overflow beyond the rule, at least using the pdf viewers that I have on my computer. 2) there appears to be some interference between setting rulethickness and columndistance, so that spaces between columns disappear when putting a thick bottomframe. Of course, one could kludge a column separation using a rightframe, but this is not satisfactory. 3) The use of a white rule when one really wants to leave some space is not very satisfying. Does anyone have any suggestions? Thanks Alan

Current status of epub export and documentation
by Jan U. Hasecke 01 Dec '15

01 Dec '15

Hi all, I am interested in the epub export feature of ConTeXt/MKIV. There are a some hints in epub-mkiv-demo.tex epub-mkiv.pdf http://wiki.contextgarden.net/ePub I am looking for a more detailed example (or documentation) to learn what is possible and what not. (Eg. \showsetup{command-name} is not exported to epub) Does anybody already made a full validated epub ebook with ConTeXt including cover, titlepage, appendix etc. ? Is there more information about the current status of the export feature? A release schedule or roadmap? Background of my question is that I am looking for a single source publishing tool for printed books and ebooks. TIA juh

Command definitions in ma-cb-en.tex
by Jan U. Hasecke 01 Dec '15

01 Dec '15

Hi all, this is a stupid question, I fear: In "ConTeXt Mark IV an excursion" in appendix A I see many command definitions. I browsed the sources of this document but could not find the point where these list is defined. I know that in setup-en.pdf there is an even longer list, but I could not find the source of this document. Can anyone shed some light on this mechanism? TIA juh

\rm for greek letters in math mode

I see the third \delta here as italic, where I would have expected it to be in roman, as for the "d" example below. Likewise for all greek letters, I think. Why is that? How can I have these in roman? \starttext \delta $\delta {\rm \delta}$\crlf d $d {\rm d}$ \stoptext Thanks, -- Kate
