Actually I had a mechanism for that but I discarded the code. However there will be a feature like that some day as it needs a rather tight integration in the core of context's font handling.

Mysterious space in first table column
by Adam C.M. Solove 25 Aug '10

25 Aug '10

I am trying to typeset a simple table with very tight spacing. The first column of the table is wider than the others with a mysterious amount of extra space added on the left. You can reproduce this with a simple example: \starttext \starttable[|s1l|l|l|l|l|l|l|l|l|] \HL \VL4\NC 1\NC 7\VL\AR \VL6\NC 3\NC 2\VL\AR \VL9\NC 5\NC 8\VL\LR \HL \HL \stoptable \stoptext I assume the problem is that I don't understand the "s1" declaring the amount of space for the cells. Reading through the docs (which have examples of tables but not a lot of introductory material), I haven't been able to find a way to remove the extra left-hand space while leaving the spacing of the remaining cells the same. --- Also a quick note, I have spent the last month converting to ConTeXt from my previous background in LaTeX and have really been amazed. I'm currently typesetting a new journal, aimed at computer programmers ( http://codequarterly.com/) and I was very quickly able to get my otf fonts working, format complicated documents, and create reusable named styles. If we're happy users of ConTeXt, what is the best way to give back to the community? Blog posts talking about it? Documentation? Conferences? Thanks, Adam Solove

varying headers, footers, page numbers
by Michael Goerz 25 Aug '10

25 Aug '10

Hi, I'm trying to create a book where the front matter has no headers/footers, except roman numeral page numbers at the top outside of the page. The main matter should have Arabic numeral page numbers (restarting with '1') at the top outside of each page, plus the name of the book in the header of each even page and the name of the chapter in the header of each odd page, with no footer. However, on the pages where a new chapter starts (which is set to always be an odd page), there should be no header, and the page number should appear centered at the bottom of the page. I'm quite confused about how to achieve this in ConTeXt. An excerpt from the project structure is ./env.tex ./project.tex ./book/book.tex ./book/chapters/chapter1.tex The following is a shortened excerpt from book.tex: \startfrontmatter \setuppagenumbering[state=stop] % nothing for now, should be roman page % numbers later \component book/frontmatter % ToC ... \stopfrontmatter \startbodymatter \setuppagenumber[number=1] \setupheadertexts [{Name of Chapter}] [{}] [{}] [{Name of Book}] \setuppagenumbering[ alternative=doublesided, % mirrored even/odd pages location={header,margin}, style=small] \component vol04_1/articles/azimov \stopbodymatter This leads to my first question: I generally try to keep all formatting definitions in env.tex. However, it seems to me that since I want to have different settings in the frontmatter compared to the mainmatter, I need to put the \setuppagenumbering and \setupheadertexts in book.tex, which slightly bothers me. The way I intuitively feel it should work is that I would define various headertexts and pagenumberings under some label in env.tex, and then activate the different configurations in book.tex via that label. Is there anything in ConTeXt that I may have overlooked that makes something like that (centrally defining several alternative header/footer/pagenumber configurations) possible? Next, the problem of having a different header/footer/pagenumber on pages where a new chapter starts. In env.tex, I have \setuphead[chapter][ page=mychapterpagebreak, number=no, alternative=c, align={center, nothyphenated, verytolerant}, style={\switchtobodyfont[16pt]}, header=high, footer=none, ] This causes the chapter pages to have no header/footer/pagenumber at all, which is halfway what I want. But actually, I don't really understands why that works either. My understanding is that "header=high" means there should be no header on the first page and the normal header on all subsequent pages. The way I've set it up though, the page number is not really part of the header (it's separately set up through \setuppagenumbering). So why does the page number disappear as well? And, of course, the main question: How do I get the page number centered in the bottom of that page? Again, I feel if there was some way to define different configurations for the header/footer/pagenumbers under different labels, e.g. a label 'chapterfooter', it would then make sense to do something like 'footer=chapterfooter', instead of 'footer=none'. But I guess that's not the way it works -- so how *does* it work? Thanks, Michael

This reminds me. Two columns of text over three columns of footnotes. Is it possible?

textext vs. btex ... etex
by Oliver Buerschaper 24 Aug '10

24 Aug '10

Hi, I've been trying to troubleshoot a problem with TeX labels I ran into the other day... finally I discovered that 1. MkIV (textext) includes TeX material as one single chunk apparently while MkII (btex ... etex) used to include a decomposable picture and that 2. the anchor point is completely different! Is there any way to restore both the "individual addressing" of glyphs and the MkII anchor point in MkIV? This would be crucial for a customized labelling macro... Best, Oliver P.S. Why is "h," included as one piece in MkII?

Tikz calendar: \pgfutil undefined
by Fabrice Larribe 24 Aug '10

24 Aug '10

Hello, I have a problem to use the calendar from the Tikz/Pgf module; here is a minimal example: %--------------------------------------- \usemodule[tikz] \usetikzlibrary[calendar] \starttext This should works: \blank \tikz \calendar[dates=2000-01-01 to 2000-01-31,week list]; \blank but this does not ! \stoptext %--------------------------------------- I'm using MKII (2010-05-24) from TeX Live 2010 (Note however that I had the same problem with TeXLive 2009). The error is when the calendar library is loaded: ! Undefined control sequence. l.36 \let\tikz@atbegin@day=\pgfutil @empty I have tried the Tikz distribution from TexLive, the latest Tikz distribution from the suport Tikz page, and the distribution from the module made for ConTeXt, but the problem remains. In the past (last academic year, in may), this worked well, but I'm not able to find what has changed. Thanks for hints and help ! Fabrice L.
