Is there a way to detect if two references are on the same page? I looking for a way to determine if I should print a single page number or a range of numbers.

Vertically centered text in each page
by Nicola 02 Mar '16

02 Mar '16

Inspired by Aditya's "make a presentation in 40 commits" example, I have defined my own environment for slides. A part of it looks like this: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startreusableMPgraphic{header:background} fill OverlayBox leftenlarged BackSpace rightenlarged CutSpace topenlarged TopSpace withcolor OverlayColor ; setbounds currentpicture to OverlayBox enlarged max(BackSpace,CutSpace) ; \stopreusableMPgraphic \defineoverlay[header:background][\reuseMPgraphic{header:background}] \define[2]\MySlide{\framed[ frame=off, background=header:background, backgroundcolor=orange, width=\textwidth, align=flushleft ]{#2}} \definehead[slide][subject] \setuphead[slide][ style=\ssb, command=\MySlide, color=white, page=yes, ] \starttext \startslide[title={Slide One}] \vfill text \vfill \stopslide \startslide[title={Slide Two}] \vfill text \vfill \stopslide \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% As you see, I am using \vfill to have the text vertically centered. How do I setup the slide command to do that by default? I have tried putting {before,after,beforesection,aftersection}=\vfill in various combinations in \setuphead, but I cannot obtain the desired effect. Related to the code above, I have another question: if I remove the comma after page=yes, slides are not split into different pages. Is it normal that a comma is required at the end of an argument list? Nicola

Re: [NTG-context] Controlling \at output

SOLVED: I cut and pasted the code from the original response and failed to notice that the very first character i.e. the ‘\’ was missing in the message. It all executed with no error messages!! Works fine with the minor correction. Thanks for your help. Aidan

I must be doing something stupid. I’ve just installed the standalone version. Saved the code as test3.tex and invoked it with context test3.tex It reports the version as ConTeXt ver: 2016.03.01 14:03 MKIV beta fmt: 2016.3.1 int: english/english And still no output from \thispage Aidan

Vim snippets
by David Nebauer 01 Mar '16

01 Mar '16

Hi, Newbie question: are there any vim snippets available for context? The context wiki vim page (<http://wiki.contextgarden.net/Vim>) makes no mention of any. I couldn't find anything on github (but there are hundreds of matches since "context" is such a generic word).

new lua error (latest beta)
by Alan Bowen 29 Feb '16

29 Feb '16

I have a number of docs that have processed properly until the latest beta. Now I get this complaint in each very early in the processing: lua error > lua error on line 39 in file xxxxxxx: ...eXt/tex/texmf-context/tex/context/base/mkiv/strc-not.lua:324: attempt to index field '' (a nil value) stack traceback: ...eXt/tex/texmf-context/tex/context/base/mkiv/strc-not.lua:324: in function 'action1' [string "..."]:6: in function <[string "..."]:5> (...tail calls...) Is this a bug or has there been some change in ConTeXt coding that I need to address? Alan

problem with page number on last page
by Alan Bowen 29 Feb '16

29 Feb '16

To prevent empty pages in a double-sided page environment, I have been using \setuppagenumbering[page=]. This does not work as it should, however, when there is no body text but only a continuing footnote on the last page. Then, though there are still no empty pages, the pagenumber on the last page is the same as that on the preceding page. Consider \setuppagenumbering[alternative=doublesided] \setuppagenumbering[page=] \starttext \dorecurse{3}{\input knuth}\footnote{\dorecurse{3}{\input knuth}} %\input knuth \stoptext with and without the line currently commented out. Any suggestions will be greatly appreciated. Alan

Customize grid layout
by Zhichu Chen 29 Feb '16

29 Feb '16

Dear TeXers, Is it possible to define the layout like: \setuplayout [grid=yes% ,lines=6% ,gridstyle={1,1,1,3.5,1,1}% ] so that I can have 6 lines per page, but the 4th line skips will be 3.5\baselineskip. For your information, the blank between the first 3 lines and the rest ones is used to display the page number (it's not a joke although April is close). I was thinking putting an invisible rule after each CJK glyph as a font feature, and the height of the rule changes every 6 lines starting from 4. But \linenumber seems to be an MKII-only counter. Any suggestions? -- Best regards, ℤhichu ℂhen Shanghai Institute of Applied Physics No. 2019, Jialuo Road Jiading, Shanghai, P.R.China Tel: +86-21-39194888
