Columns and clubpenalty problem
by Thomas Floeren 07 Mar '14

07 Mar '14

Hi, with the recent Betas, and the Current, I have a problem with columns and clubpenalty. In the following minimal the long item (item 1) will introduce a column break (instead of a simple line break): \def \defaultclubpenalty{\plustenthousand} \starttext \startitemize [columns] \item This is just a long line and should stay in the left column. \dorecurse{10}{\item bla bla bla} \stopitemize \stoptext Older ConTeXt versions work as expected (no column break in item 1), for example Beta 2013.11.13 12:28 or Current 2013.05.28 00:36.

What’s wrong with \nomarking{\crlf}?
by Henning Hraban Ramm 07 Mar '14

07 Mar '14

Hi, I’m trying to get a linebreak into a heading, but not in the ToC. I thought \nomarking{\crlf} would be the way to go, but \crlf seems to be undefined, as well as \nomarking?? (Latest beta on OSX.) \starttext \startchapter[title={It’s a long way to Tipperary,\nomarking{\crlf} it’s a long way to go}] \include knuth \stopchapter \completecontent \stoptext Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Combination maxwidth
by pol stra 07 Mar '14

07 Mar '14

Hello, I tried to use a combination in a placefigure command with two figures side by side: \placefigure[2][ref]{figure caption} {\startcombination {subcaption 1} {\externalfigure[myfigure1]} {subcaption 2} {\externalfigure[myfigure2]} \stopcombination } But the result doesn't fit into the pagewidth. Is there maxwidth command like for combinations ? Or there is a way to get distance so I could set myfigure1 and myfigure2 maxwidth to 0.5*(\textwidth - distance) ? Thanks

Bug: Columnar itemized text
by Thangalin 06 Mar '14

06 Mar '14

Hi, I believe I have isolated the problem: \starttext balance \startmixedcolumns[balance=yes,] \dorecurse{8}{\input{ward}} \stopmixedcolumns %\page strut \startmixedcolumns[grid=strut,] \dorecurse{4}{\input{knuth}} \stopmixedcolumns \stoptext When balanced mixedcolumns are followed by mixedcolumns using a strut grid, then the content of the second mixedcolumns will extend into the footer area on the next page. However, if the content of the strut grid mixedcolumns is long enough to incur a page break on that next page, then no content spills into the footer. How can I help fix this?

Trimming strings and Lua string.trim question
by Rik Kabel 06 Mar '14

06 Mar '14

I am trying to strip all leading and trailing whitespace from a string. I have tried two methods, neither of which is satisfactory. The first method uses \ignorespaces and \removeunwantedspaces. This fails to strip leading and trailing newlines. The second method uses the Lua string.strip function. The wiki description: Yields string with leading and trailing whitespace (spaces, horizontal and vertical tabs, newlines) removed suggests that this should do what I want, but I find that it removes internal whitespace as well as the leading and trailing whitespace. Can somebody suggest a better way of doing this? The following code demonstrates the problem: % macros=mkvi \starttexdefinition StringStrip #STRING \startluacode context(string.strip([==[#STRING]==])) \stopluacode \stoptexdefinition \long\def\test{ This is a test. \quad And it has an unexpected result. With \tex{ignorespaces} and \tex{removeunwantedspaces}, the newlines remain. With Lua {\tt string.strip}, the \tex{quad} at the end of a paragraph is preserved, but the other internal whitespace (including newlines) is gone! } \starttext \subject{ignorespaces and removeunwantedspaces} ¦\ignorespaces\test\removeunwantedspaces¦ \subject{Lua string.strip} ¦\StringStrip{\test}¦ \stoptext -- Rik

Placing marks at edge.
by john Culleton 06 Mar '14

06 Mar '14

You have seen them in books from O'Reilly and even in books like "TeX for the Impatient": markings on the outer edge of each odd page that bleed past the page edge indicating a particular chapter. In the last named they are a simple box with very fine horizontal black lines. In some O'Reilly books like "Web Design in a Nutshell" they are a black box with the chapter name (possibly abbreviated) rotated 90 degrees in small white text. No doubt I can do this in Context. The question is what is the simplest and most foolproof way home. Of course the page size will be made larger by 0.125 inch on all sides except the spine edge to provide a trim. The marker box I describe protrudes into the trim area. And its location and the text change for each chapter of course. It is very hard in this country to get a book review by the important pre-publication reviewers like Booklist and Library Journal. But that review is the key to among other things library sales and academic sales. Edge markings like I discuss above will immediately separate my books from those slapped together in MSWord etc. I am just trying to get my books past the clerk in the mail room who has orders to discard anything that looks self-published. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

Selectfont: extend and slant features
by Joshua Krämer 05 Mar '14

05 Mar '14

Dear list, the (fake) extend and slant features seem to be missing with Selectfont. Will they be made available sometimes in the future? Or am I simply doing something wrong? With simplefonts, they work. \definefontfeature [mainfeature] [default] [onum=yes] \definefontfeature [testfeature] [onum=no, extend=2, slant=0.25] \definefontfamily [mainfamily] [serif] [Latin Modern Roman] [features={mainfeature}] \setupbodyfont [mainfamily, 50pt] \starttext 1236 \addfeature [testfeature] 1236 \stoptext Kind regards, Joshua Krämer

(critical edition) wrong page breaks with linenotes
by Pablo Rodriguez 04 Mar '14

04 Mar '14

Hi Thomas, Luigi and Hans, I have a sample (http://www.ousia.tk/hefestio-ctx.tex) that shows problematic page breaks with notes in paragraph form. This is especially relevant for linenotes in critical editions. The compiled version (http://www.ousia.tk/hefestio-ctx.pdf) shows results at twelve, thirteen and fourteen points. I know I’m using a font that is not part of the ConTeXt Suite, but it is the one that gives me the faulty results. Of course, it isn’t the only problematic one. In the source, \setupnote is set in both linenotes to [split=verystrict, scope=page] to avoid having linenotes that refer to a line from the previous page. If I’m not missing something or doing something wrong, I think that a way to solve this (sorry, I don’t know the internals, but the suggestion might be a valid one) is to set a kind of penalty that does the following: if the line in its final position doesn’t observe the space before of the first apparatus, it should be moved to the next page. Isn’t this proposal similar to the way widow and orphans are avoided by setting penalties? Many thanks for your help, Pablo -- http://www.ousia.tk
