Referencing Itemized Items?
by Michael.Urban＠jpl.nasa.gov 03 May '08

03 May '08

Is there some way to set up a reference tag so that I can refer to a particular item in a list, e.g., something vaguely like: You must do the following steps: \startitemize[n] \item Buy the ingredients \item Cook the food \item [??????] Put out the fire \stopitemize Note that Step \in[?????] is optional for experienced chefs. It looks like there are mechanisms to support this in the tex code, but I don't know how to use them.

Itemize numbering
by richard.stephens＠converteam.com 02 May '08

02 May '08

Hello All, I just tried the following on Context Live: \starttext \startitemize[n] \item one \item two \startitemize \item a \item b \stopitemize \item three \stopitemize \stoptext and the first itemize starts at 0. Remove the inner itemize and it starts at 1. Is this a feature or a bug? How do I get around it? Thanks, Richard

two small questions about the mkiv roadmap
by Thomas A. Schmitz 02 May '08

02 May '08

Hi all, esp. Hans and Taco, just two simple questions about some minor imperfections in mkiv/ luatex. I'm not impatient, just wondering if these are things that you're working on right now or if they will have to wait: 1. processing xml files with a DTD. This is something we discussed a couple of weeks ago: when I process a valid xml file which begins with a DTD, the output I get in mkiv is "invalid xml file"; the same file processes fine when I remove the DTD. Back then (on 08-03-17), Taco wrote: "It is a bug in luatex, but not an easy one to fix." So I'm wondering if there's any progress on this one, or if it has to wait. 2. error reports in luatex. This is something that comes up time and again on the mailing list and which I experienced myself yesterday. I had inadvertently deleted my luatex-cache and tried to run mkiv on a file. The report I got was "attempt to call field 'error' (a nil value)". Now I'm aware that TeX error reporting could be cryptic at times, but at least it was a kind of cryptic to which we had gotten used. With luatex, I'm constantly baffled - in a 100 years, I wouldn't have guessed that this error message meant "I can't find the cache and the format." So I was wondering if this is something that you're working on: making error messages more informative/comprehensible for users. Again, I'm not impatient, just curious. All best Thomas

Trouble with Index
by cidadaum＠sapo.pt 01 May '08

01 May '08

So far I have not succeded to make an index in a book I am typesetting. I write something like: \starttext \defineregister[index][indices] \index[Tantrum]Tantrums can be normal for \index[tantrum][tantrum+toddlers]toddlers. Young children have them for many reasons like being tired, feeling out of control, over-stimulated, or wanting something they can't have. General hints: Toddlers and preschoolers cannot regulate themselves because they don't yet know their own limits. \completeindex \stoptext And the message I get is: "index not found/processed". In the pdf appears a page with Index but no entries.

\indenting[next] and math => no vertical space before the formula
by Mikael Persson 30 Apr '08

30 Apr '08

Dear all, I have a problem with \indenting[next] combined with math formulas. Look at the example below. The space between the text above the formula and the formula is way to small. This goes away if I change next to for example yes. Btw, this happens on my TeXLive 2007 on ubuntu at home, my ConTeXt minimal from 2007-04-03 at work and on live.contextgarden.net (with pdfTeX but not LuaTeX). Do I misuse the indenting macros? Thanks, Micke P % test file \setupindenting[yes,small] \indenting[next] \starttext Hello World! This is just some dumb text to show the problem. \startformula a=b \stopformula Goodbye World! The space below the formula is OK. \stoptext

Table of contents customization
by Noé Cuneo 30 Apr '08

30 Apr '08

Hi all, I've been using ConTeXT for quite a while now, and I am trying to build my own customized environnment. I have some trouble customizing my content table. I tried everything I could, including reading the manual twice over, and I still can't figure out why none of my ideas will work! In fact, my configuration looks like this: \setupcombinedlist[content][level=4,alternative=c] \setuplist[chapter][width=7mm,style=bold] \setuplist[section][width=10mm,margin=10mm] \setuplist[subsection] [width=13mm,style=slanted,pagestyle=normal,margin=21mm] What I would like is the number to be separated from the page name by a ".", which would give something like: 1. Chapter name................. 32 I tried \setupcombinedlist[content][level=4,alternative=c, separator={.}], but it doesn't work. Although 'separator' is documented as the separator between the number and the pagename, it appears to be the separator between the number and subnumbers, like, with separator={ppp}: 1 MyChapter ............ 1ppp1 Mysection.......... Which is not quite what I expect! So i tried setting something like \def\mycommand#1{#1.} \setupcombinedlist[content][level=4,alternative=c, numbercommand={\mycommand}] Which works, except for the fact that when there is no number (like in my frontmatter), the "." is shown anyway... So I naturally tried: \def\mycommand#1{\doifnotempty{#1}{#1.}} Which doesn't work! I still get something like . Preamble 1. ChapterOne 1.1 Section So even if no number is given, the doifnotempty block still is executed! I tried a lot of combinations, like \def\mycommand#1{\doifdefined{#1}{#1.}} or \def\mycommand#1{\doifnot{#1}{}{#1.}} But none of these will compile... So at this point, I don't see any solution, which is why I really would appreciate any suggestion! Thank you very much!

Have you found that whitespace? Aren't the foldmarks positioned in absolute values relative to the page? There is no whitespace involved, isn't it? So I don't understand this 5mm offset at all.

columns and \definemakeup
by Suno Ano 30 Apr '08

30 Apr '08

Hi Folks! I am in the curse of setting up the environment plus a project structure for a book. My problem is with a few pages like for example colofon where I used ,----[ content from comp_colophon.tex ] | \startcomponent comp_colophon | \product prod_back_matter | \project proj_a_book | | \startstandardmakeup[doublesided=no, page=right] | | \startalignment[flushleft] | \ssd Colophon\par | \blank[1mm] | \ssa \title\par | \stopalignment | | \hairline | | \stopstandardmakeup | | % ------- | | \startstandardmakeup[doublesided=no, page=left] | \stopstandardmakeup | | | \stopcomponent `---- Now I want the text to be in columns -- two that is ... However, I tried with ,---- | \startcolumns[n=2] | <my text goes here> | \stopcolumns `---- and ,---- | \definecolumnset[example][n=2] | | \starttext | \startcolumnset[example] | \dorecurse{15}{\fakewords{100}{200}\par} | \stopcolumnset | \stoptext `---- but I just get one column in both cases. Can anyone tell me how I would for example use \definemakeup in order to get exactly what \startstandardmakeup and \stopstandardmakeup provides me with PLUS the text gets typeset into two columns? Maybe if it is not possible with \definemakeup what else could I do? Tia!
