If needed, it breaks the page not at the positon of a divider, but sooner, so that divider is preceded at least with 2 lines of text. \page[no]\blank[4mm]\middlealigned{\hl[4]}\blank[6mm] Jan

OT: Reflections on usability ConTeXt for typesetting of mathematics
by Jaroslav Hajtmar 13 Feb '14

13 Feb '14

Hello ConTeXist. I am very sorry for this OFF TOPIC contribution. For writing of this text led me several hours of searching on internet. I was looking for ways to typing of non-elementary math in ConTeXt Already a long time I use ConTeXt typesetting lot of different things and I am very satisfied. In the many things, of which I typed, was maths represented only marginally and minimally. Now I need to type some mathematics (at secondary school level) and I found that I came across borders of my knowledge of ConTeXt, or on possibilities of ConTeXt for typesetting of mathematics. I do not in any way call into question the ability of ConTeXt typesetting mathematics, although I think that who wants to type mathematics then use LaTeX. I want find experience of users of ConTeXt for real using of ConTeXt for typesetting of mathematics. I wonder how users use possible math modules (exist anything?) to be usable results. I have a few questions: 0. Do you think that this is only a problem for beginners of ConText or it is a general problem of ConTeXt? 1. How many of ConTeXt users use this tool for typesetting of non-elementary mathematics? 2. Are you satisfied with the results, which produces ConTeXt (thinking in the field of mathematics rate)? 3. What things do you need to have in ConTeXt study that one could bet mathematics at a reasonable level? 4. Is ConTeXt able to substitute LaTeX to typesetting of math (e.g. in the future)? 5. Can you think of any more questions that should be here? I hope that my question will help other beginners who would like to typing of mathematics use ConText - this unique and useful tool. Thanks for all the answers. Jaroslav Hajtmar

textwidth in (simple)columns
by Hans van der Meer 13 Feb '14

13 Feb '14

With \startcolumn[n=2] the \textwidth appears as the columnwidth, but with \startsimplecolumns[n=2] it stays the full breadth of the page. Is there a remedy? Changing to \startcolumns is no option because it does not work inside \startframedtext, and \startboxedcolumns is no option because I found cases where (apparently with a clear cause) sometimes material disappeared (I posted here a remark on this sometime ago) Hans van der Meer

suggestion on [option=TEX]
by Pablo Rodriguez 12 Feb '14

12 Feb '14

Hi Hans, I have the following sample: \setuptyping[option=TEX] \starttext \starttyping \input zapf % knuth \stoptyping \stoptext The percent character is in bold font and gray color, but the rest of the commented text isn’t. My suggestion would be to apply the same color and font of the percent character to the rest of the comment. So it is easier to see that the text is a comment. And I think coloring the whole commented text (not only the percent character) is the normal practice in all text editors (if comments are colored at all). Many thanks for your help, Pablo -- http://www.ousia.tk

state=high vs state=empty for headers and footers
by Aditya Mahajan 12 Feb '14

12 Feb '14

If one uses \setuplayout[header][text][frame=on] then the frame is drawn on pages with header=empty but not drawn on pages with header=high. By default, the 'empty' pagebreak method (in page-txt.mkvi) sets the header and footer state to empty rather than high. This means that header frames are drawn on empty pages. For example, see attached file. Would it make sense to change the definition in page-txt.mkvi to the following: \installpagebreakmethod \v!empty {\page_otr_flush_all_floats \page_otr_command_next_page \doifnot{\namedlayoutelementparameter\v!header\c!state}\v!stop{\setuplayoutelement[\v!header][\c!state=\v!high]}% \doifnot{\namedlayoutelementparameter\v!footer\c!state}\v!stop{\setuplayoutelement[\v!footer][\c!state=\v!high]}% \page_otr_insert_dummy_page} \installpagebreakmethod \v!header {\doifnot{\namedlayoutelementparameter\v!header\c!state}\v!stop{\setuplayoutelement[\v!header][\c!state=\v!high]}} \installpagebreakmethod \v!footer {\doifnot{\namedlayoutelementparameter\v!footer\c!state}\v!stop{\setuplayoutelement[\v!footer][\c!state=\v!high]}} or, if that is too drastic of a change, create a new pagebreakmethod called high. This request is motivated by: http://tex.stackexchange.com/q/110701/323 Aditya

When you have characters with big ascenders/descenders you have to increase the interlinespace or change the height/depth ration of a strut. 1. Change the interlinespace value with \setupinterlinespace[line=14pt] 2. Change the height/depth ration with \setupinterlinespace[height=0.8,depth=0.2] % default: height=0.72,depth=0.28 Wolfgang

getting text outside cropmarks to work
by Lars Huttar 11 Feb '14

11 Feb '14

Hello, Under mkii we used to have a running footer that appeared below the crop marks. Under mkiv I can't get that to work. The MWE I'm trying (with ConTeXt mkiv from the TeXLive 2013 CD): \def\TopText { Top Text } \def\BottomText { Bottom Text } \def\pagecutmarksymbol {\the\realpageno} \def\pagecutmarklength {.5cm} \let\pagecutmarktoptext \TopText \let\pagecutmarkbottomtext \BottomText \setuplayout[marking=text] %\setuplayout[marking=on] \starttext \input knuth \stoptext Code like this used to work for us in mkii. I tried it with both marking=text and marking=on, but in either case, I get neither crop marks nor the text. (In our real document, I was able to get crop marks with [marking=on]. But not text. And haven't figured out how to get crop marks in a MWE.) Relevant guidance I've been trying to follow: http://wiki.contextgarden.net/Imposition#Cut_marks http://context.markmail.org/thread/kpayudrtabsti76i Thanks for any help on how to get text (pagecutmarkbottomtext) to appear outside the crop marks.

(Combined)lists, two questions
by Robert Blackstone 10 Feb '14

10 Feb '14

Dear all, I have a few issues with the Table of Contents and with the List of Figures 1 How can one force a page break after some section. In my present setup I have a Chapter 4, sitting lonely at the bottom of the first page of the ToC, with its sections on the next page. I have tried \completecontent[3.7], as described on p. 53 of "ConTeXt an excursion", but that does not work for me (I'm on mkiv). What can be done about it? 2 My list of figures gives the complete captions, some of which are long. Those exceeding their allotted space break off, which is OK, but there are some that run up against the page number, which is ugly and unclear. What can I do the create a little more space between caption and page number? In general, of most if not all of the 38 possible arguments for \setuplist, as shown on http://wiki.contextgarden.net/, I do not know what they do and how they can be used. Unfortunately, also "ConTeXt an excursion" is very brief on this subject. Is there any place where I can find more information? Thanks in advance for ay advice. Best regards, Robert Blackstone
