Specifying leading?
by Bill Meahan 14 May '12

14 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

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.

indexing query

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

Did usage of \expanded changed?
by Peter Schorsch 11 May '12

11 May '12

Hi, I "reactivated" some code that was working a year ago. But now it seems that \expanded has no effect in my case (see below). I also tried it with \normalexpanded and \expandedafter but both had also no effect. My problem seems to be this line of the full example below: \doifsomething\Paragraphmark{\expanded{\textreference[\Paragraphmark]{\fullheadnumber/\rawnumber[ParagraphNumber]}}}% The error shows itself in the line: Should be 1/1: \in[test] As \in[test] gives me 1/3 instead of 1/1. (1 was the number assigned to the first paragraph - 3 is the acutal number). Can someone tell me what I need to change? Thanks in advanced P. -----8<-------full example------------------- \unprotect \definenumber[ParagraphNumber][way=bysection,prefixsegments=100] \unexpanded\def\startParagraph {\dosingleempty\dostartParagraph} \def\dostartParagraph[#1]% {\getrawparameters[Paragraph][heading=,mark=,#1]% \incrementnumber[ParagraphNumber]% \ininner{\tfx\getnumber[ParagraphNumber]}% \doifsomething\Paragraphheading{\inouter{\Paragraphheading}}% \doifsomething\Paragraphmark{\expanded{\textreference[\Paragraphmark]{\fullheadnumber/\rawnumber[ParagraphNumber]}}}% \ignorespaces} \unexpanded\def\stopParagraph {\blank[medium]} \protect \starttext \chapter{Alter novom} \startParagraph[heading={lorem ipsum},mark=test] \input tufte \stopParagraph \startParagraph \input tufte \stopParagraph \startParagraph Should be 1/1: \in[test] \stopParagraph \stoptext

Strange crash when using lxp library

Hello, I have a strange problem. I tried to prepare the simplest example. Let's have a table utility in 'Table-U_.lua' (to be placed to LUA_PATH): ---- table.fromExcelXML = function(fn) ... tabs[true] = true -- Comment this line to make it work(?!) [1] ... end if not context then require "lxp" print("\n777777") table.fromExcelXML("InzSiteLitom_Nove.xml") print("\n888888") end ---- When you call it from the command line, it works fine: ---- C:\Lukas\ConTeXt\TestDDv>lua -e require'table-u_' 777777 888888 ---- When used in a context file: ---- \mainlanguage[cz] \enableregime[cp1250] \startluacode require "lxp" require "Table-U_" print("\n111111") table.fromExcelXML("InzSiteLitom_Nove.xml") print("\n222222") \stopluacode \starttext AAA \stoptext ---- it crashes with an exception in luatex: " Exception "unknown software exception" 0xc000000d" at 0x1028e4c3. ... " Would anyone have an idea what causes the program crash? I also observed that commenting a line [1] in the "Table-U_.lua" makes context work; but the place seems "innocent", so I have no idea what can cause ctx crashing. Could anyone test the code, respectively give a hint how to make the [simplified] code work? All ideas are welcome. Thank you in advance. Best regards, Lukas -- Ing.
