atpage || number comparing
by Peter Schorsch 15 May '12

15 May '12

Hi, it tried to do a \atpage command that results a) some page => nothing b) different page => pagenumber with some text (e.g. "auf Seite XY") \def\atPage[#1]% {\doifnot{\at[#1]}{\currentpage}% {\at[#1]}% } My problem with this is, that the \doifnot always results as not equal; it is like the types mismatch as if I exchange \at[#1] with a pure number the comparing works. If so, how can the types be corrected? Additionally - if possible - I would like to add case that the referred page is on the other page but in duplex mode adjacent to the actual page. Is that possible to do this? I unluckily dont know how to make working simple calculation in tex code. To be complete I found in the file strc-ref.mkiv some notes about a planed \atpage command: %D A still very rudimentary|/|experimental forward|/|backward %D reference mechanism is provided by the macro \type{\atpage}: %D %D \starttyping %D ... \somewhere{backward text}{forward text}[someref] ... %D ... \atpage[someref] ... %D \stoptyping %D %D In future versions there will be more sophisticated % 0 = no page reference % 1 = same page % 2 = preceding page % 3 = following page % 4 = backward, same page (todo) % 5 = forward, same page (todo) But that level of the ambient tex is still out of my scope. Thanks P.

mutual color definition
by Peter Rolf 15 May '12

15 May '12

Hi, while playing around with colors, I accidentally used two mutual color definitions. Stupid thing to do, but shit happens. :-D This example ends in an infinite loop. %---------------------- \definecolor[foo][red] \definecolor[bar][foo] \starttext \definecolor[foo][bar] \color[foo] foo \color[bar] bar \stoptext %---------------------- Regards, Peter

Yes it works. The only problem is that now I have the formulas aligned at the center of the page. Which command can I use to align the formulas on the left?

Specifying leading?
by Bill Meahan 15 May '12

15 May '12

How does one specify leading in ConTeXt? In traditional typography, it is common to specify the type size and leading to indicate the inter-line spacing of a block of text. Setting type "solid" means to use no spacing between lines - not usually a good idea ;-) More often, good typography requires a minimum of two points of leading between adjacent lines and might be specified as 12/14 or 12/15 meaning to set twelve-point type on a fourteen or fifteen point "leading" resulting in inter-line spacing of two and three points respectively. Is there an easy way to specify this in ConTeXt or must I muck about with baseline skip? I have tried looking this up on the wiki and in the font documentation but it either is not there or is worded in such a way I am not recognizing it. I'm using MkIV -- Bill Meahan K8QN "I want to live other lives. I've never quite believed that one chance is all I get. Writing is my way of making other chances." -- Anne Tyler

color as module parameter (mkiv)
by Peter Schorsch 14 May '12

Hi, I am trying to pass a tex color as a paramter to a module. I used the example from the wiki as a base. But as soon I hand over a color directly it does not work. Any help is welcome as I am looking forward to hand in my first module. Are there any rules how and where to hand in a module for context? Thanks P. --8<---Modul: bgcolor.tex--------------- \startmodule[bgcolor] \unprotect \definecolor[grau][s=.35] \setupmodule[color=grau] \setupbackgrounds[page][background=color,backgroundcolor=\currentmoduleparameter{color}] \protect \stopmodule \endinput --8<--tex file itself--------- \setupcolors[state=start] \definecolor[bordeaux][r=.66] \usemodule[bgcolor][color=bordeaux] \starttext Hello world! \stoptext

hvdm-exm module fails
by Martin 14 May '12

14 May '12

Hi, I am trying to make use of the "hvdm-exm" module for a series of tests and that fails. Below is the basic code I am using. As I could not find a usage sample, I might have it wrong. It fails with \startexam as "undefined" and an internal message that it seems to have a language problem (WARNING ? unknown -- current language en tried). Looking into the file hvdm-exm.tex I can find the source of the error message, but it's beyond me to really understand what's going on. My ConTeXt is updated as of today (30.4.2012). I updated the core file "hvdm-exm.tex" to the 2010-11-17 version but that has no obvious influence. Also checked permissions (just to be sure, folders 755, files 644) and fixed them with no impact. Afterall, the files are all loaded. http://archive.contextgarden.net/message/20101212.154453.528d5fd7.en.html Help would be much appreciated.

Sorry for having given you a non working example! Here you can find a working one. The comments at the end of each line are in italian. Changing the height of the frame you can move the \startalign content in the page. As you will see, the whole content flows from one page to the following, without splitting at the right line.

I am trying to construct an index of passages and have run into a curious problem: The test file is: \defineregister[Passage][Passages] \setupregister[Passage][n=1,% balance=yes,% pagestyle=\tfx\em,% textstyle=\tfx,% criterium=all,% interaction={pagenumber},% ] \setupregister[Passage][indicator=no,distance=0.5em] \starttext See \Passage{Simplicius+{\em In de caelo}+483.15--19}483.15--19. \page See \Passage{Simplicius+{\em In de caelo}+477.3--4}477.3--4 \page \placeregister[Passage] \stoptext The result is an index that puts 483.15–19 *before* 477.3–4 as in Simplicius In de caelo 483.15–19 1 477.3–4 2 rather than after. How can I fix this? Alan
