Delayed page layout change?
by David Brooks 11 Jan '15

11 Jan '15

Hi, I'm new to ConTeXt (although have used LaTeX in various ways over a long time) and am impressed! Many thanks for a great system. I'm wanting some pages in a book to have a different layout to others, and am using \definelayout and \setuplayout to do so. This all works, including adding layers to the different layouts. However the layout change (specified by \setuplayout) occurs immediately after the command is given, which means following paragraphs on the page have the layout's new width and not the width used for earlier text on the page: i.e: + + xxxxxxxxx xxxxxxxxx xxxxxxxxx <-- \setuplayout xxxxx xxxxx + + + + xxxxx xxxxx xxxxx xxxxx xxxxx xxxxx + + Is there anyway to defer the change in layout so that it occurs when the next page starts?? I can obviously force my own page breaks using \page and give \setuplayout immediately afterwards, but this doesn't allow for paragraph text to flow over the page boundary. Thank you. David Brooks

The \ConTeXt macro and sans serif fonts
by Gerben Wierda 11 Jan '15

11 Jan '15

I want to use the \ConTeXt macro (so the colofon says \ConTeXt was used), but I'm using the Optima font. The result is pretty ugly. With a standard serif font that looks OK, as the n of Con would touch the serif of the upper side of the T if moved more to the right but with a sans serif font, a 'hole' exists between Con and TeXt: Is it OK to define my own \ConTeXt so that the kerning is more pleasing? G PS. I'm obviously close to finsihing the book if this is what I worry about.

Reference to prologue becomes "Chapter 1"
by Gerben Wierda 10 Jan '15

10 Jan '15

I have a chapter in the frontmatter that has no chapter number. The first chapter in the real book is Chapter 1. But when I refer to \in{chapter}[prologue], what I get is "chapter 1". Is there a way I can make \in{chapter}[prologue] return something like "the prologue"? I'm using mkii G

Second-level itemization and indenting question
by Gerben Wierda 10 Jan '15

10 Jan '15

I have the following setup (in mkii) \definemeasure[CAindent][12pt] \setupindenting[yes,\measure{CAindent}] \setupnarrower [ left=\measure{CAindent}, right=\measure{CAindent}, middle=\measure{CAindent}] \setupitemize[each][margin=\measure{CAindent}] \starttext \input knuth \startitemize[joinedup,packed] \item \input tufte \startitemize[joinedup,packed] \item \input tufte \stopitemize \input tufte \stopitemize \stoptext The result is that quotations at first level are perfectly aligned with the indentation of the first line of a paragraph at first level. But the itemizations at second level are not. They are slightly less indented than the indentation of the first line of the paragraph in the first-level item. This can be seen at the last "We thrive" in the example, just after the second-level item. What can I do about that? G

pagebreak after columns
by Thomas A. Schmitz 10 Jan '15

10 Jan '15

Hi all, a somewhat belated happy new year to all of you! I’ve come across what seems to be a very old bug (I have found references to it in the mailing list from about 10 years ago): I get an unwanted page break after every column environment. Here’s an example with two different ones: \definecolumnset [mine] [n=2,balance=no,distance=1cm] \definemixedcolumns [mycolumns] [n=2,balance=no,distance=1cm] \starttext \input ward \startcolumnset [mine] \input ward \column \input ward \stopcolumnset \input ward \page \input ward \startmycolumns \input ward \column \input ward \stopmycolumns \input ward \stoptext Is this fixable? Thanks, and all best Thomas

About the macro ulcircle

Hi, I discovered some macro Metafun particular. I then wanted to outline, but it does not fit with the boundary of the quadrant. Can I have some explanation ? Best regards, Fabrice \starttext \startMPcode u:=1cm ; pickup pencircle scaled 1pt ; fill ulcircle scaled 8u withcolor lightgray ; fill llcircle scaled 2u shifted (1u,0) withcolor lightgray ; fill lrcircle scaled 4u shifted (1u,1u) withcolor lightgray ; fill urcircle scaled 6u shifted (0,1u) withcolor lightgray ; label.lft(btex $x$ etex, (0,0.5u)) ; fill unitsquare scaled 1u withcolor lightgray ; draw unitsquare scaled 1u ; draw (-4u,0)--(0,0) dashed evenly ; draw (0,1u)--(0,4u) dashed evenly ; draw (1u,1u)--(3u,1u) dashed evenly ; draw (1u,0)--(1u,-1u) dashed evenly ; draw (-4u,0){up}..(0,4u)..(3u,1u){down} ; \stopMPcode \stoptext

dealing with the lang attribute in XML
by Pablo Rodriguez 09 Jan '15

09 Jan '15

Dear list, I’m trying to write an environment to typeset HTML generated by pandoc with ConTeXt MkIV. One of the issues I’m experiencing is dealing with the lang attribute. The required sample: \startbuffer[demo] <doc lang="en"> This is an English paragraph. Aber dieser Absatz ist auf Deutsch und enthält Spanisch (prueba). </doc> \stopbuffer \starttext \hsize\zeropoint \startxmlsetups xml:initialize \xmlsetsetup{#1}{p|doc|span}{xml:*} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \mainlanguage[\xmlatt{#1}{lang}] \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \begingroup\language[\xmlatt{#1}{lang}]\xmlflush{#1}\endgroup\par \stopxmlsetups \startxmlsetups xml:span \begingroup\language[\xmlatt{#1}{lang}]\xmlflush{#1}\endgroup \stopxmlsetups \xmlprocessbuffer{main}{demo}{} \stoptext The question is how to deal with the lang attribute in a single xmlsetup (at least for p and span [not all those elements might have a lang attribute, they can inherit it]). And a second question would be: how can I deal with language values in XML and ConTeXt? A \processaction command? Many thanks for your help, Pablo -- http://www.ousia.tk
