baseline alignment
by Vit Zyka 09 Sep '04

09 Sep '04

Hallo, for text positioning in a layer I needed alignment to baseline. I do not known if I missed something but I did not find it in the current ConTeXt. So I did that. Baseline is choosen by capital 'B' in the position parameter. ('B' is adopted from grahicx LaTeX/plain package.) Also I add \ctop, \ltop, and \rtop in sence of \cbox, \lbox, and rbox, respectively. I suggest to add the macros to core-box and supp-box.

nath catcode issues
by Nikolai Weibull 25 Aug '04

25 Aug '04

It seems that the code to enable catcode handling in nath math mode isn't working. Currently, nath uses \appendtoks % \livechars@ \def({\delim@l 1\ch@lparenthesis} \def){\delim@r 1\ch@rparenthesis} \def[{\delim@l 1\o@lbrack} \def]{\delim@r 1\o@rbrack} \def>{\gt} \def<{\lt} \def!{\factorial} \def,{\@comma} \def;{\@semicolon} \def`{\abbreviation} % \killchars@ \to\everymath to set it up, but as far as I can see this doesn't actually do anything as \@comma doesn't get invoked for commas and \dots always renders like \cdots. Am I missing something perhaps? Furthermore, \def\over{\n@err{Disabled command \string\over } {No more a valid command. Replace {A \over B} with \frac A B.}} \def\atop{\n@err{Disabled command \string\atop } {No more a valid command. Use array instead.}} \def\choose{\n@err{Disabled command \string\choose } {No more a valid command. Replace {A \choose B} with \binom A B.}} also messes up stuff in core-ref.tex for example: ! Disabled command \over. \n@err ...rrhelp \expandafter {#2}\errmessage {#1} \natherrormark l.46 \indent\inchapter[definitions], \about [definitions], covers the definit... ? Which I don't quite understand, but core-ref.tex has the line \definecommand over {\dospecialover} which I suppose could be troublesome. nikolai -- ::: name: Nikolai Weibull :: aliases: pcp / lone-star / aka ::: ::: born: Chicago, IL USA :: loc atm: Gothenburg, Sweden ::: ::: page: www.pcppopper.org :: fun atm: gf,lps,ruby,lisp,war3 ::: main(){printf(&linux["\021%six\012\0"],(linux)["have"]+"fun"-97);}

Hello all, I am new on this list, trying these days to learn about context and considering switching from laTex to context. I have downloaded and unzipped the mbib package but not found *any* installation instructions, only some files plus a very brief README. So can anyone tell me what should I do with those. my TeX installation is teTeX TIA, -- Jean Magnan de Bornier 3 Cours Victor Hugo, 13980 Alleins France Tel: 04 90 59 33 94 Port: 06 09 17 35 87 mèl: jm.bornier*at*free.fr

Hi, The previous post was wrong; I was playing with write tests recently and send an old fragment; the right one is: sub RunFiles { my $currentpath = cwd() ; # test if current path is writable if (! -w "$currentpath") { print " current path readonly : $currentpath\n"; if ($ENV["TEMP"] && -e $ENV["TEMP"]) { $RunPath = $ENV["TEMP"] ; } elsif ($ENV["TMP"] && -e $ENV["TMP"]) { $RunPath = $ENV["TMP"] ; } } # test if we need to change paths if (($RunPath ne "") && (-w "$RunPath")) { print " changing to path : $RunPath\n"; $InpPath = $currentpath ; chdir ($RunPath) ; } # start working if ($PdfArrange) { Hans ------------------------------------------------------------------------- Hans Hagen | PRAGMA ADE/POD/CTS Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: +31 (0)38 477 53 69 | fax: +31 (0)38 477 53 74 | www.pragma-ade.com ------------------------------------------------------------------------- information: http://www.pragma-ade.com/roadmap.pdf documentation: http://www.pragma-ade.com/showcase.pdf -------------------------------------------------------------------------

Disappearing headers
by Matt Gushee 11 Aug '04

11 Aug '04

Hello, all-- I am trying to format a book such that the book title appears in the header of each left-hand page, and the chapter title appears in the header of each right-hand page. I think (though I haven't decided for sure) that I want each chapter to start on a right-hand page. It seems that, when chapters are forced to begin on right-hand pages, the book title fails to appear on the first blank page inserted to move the chapter start, and on all subsequent pages. Here are the commands I am using related to headers: \setuphead [title] [align=left,textstyle={\switchtobodyfont[BernhardModern]\bf}] \setuphead [chapter] [page=right,head=nomarking,after=\blank] \setuppagenumbering [alternative=doublesided,location=margin] \setupheader [style=\it] \setupheadertexts [] [chapter] [title] [] % reverse order, as mentioned in my earlier post With all these commands enabled, I get the effect I want: chapters begin on righthand pages, the title and chapter title appear, respectively, in the left and right page headers (adjacent to the page numbers, with the page numbers toward the outside edge of the page). But, as I said, the book title stops appearing as soon as a blank page is inserted to move the chapter start to the right. If I comment out *both* the \setuphead [chapter] command and the \setuppagenumbering command, the title continues to be displayed throughout the text. If I enable either of the two, the title disappears again. By the way, it appears that this \setuppagenumbering command has a side-effect of forcing chapters to begin on the right. Is that really a good idea? It's certainly surprising to me. So, am I doing something wrong, or is this a bug? -- Matt Gushee When a nation follows the Way, Englewood, Colorado, USA Horses bear manure through mgushee(a)havenrock.com its fields; http://www.havenrock.com/ When a nation ignores the Way, Horses bear soldiers through its streets. --Lao Tzu (Peter Merel, trans.)

Converting math from LaTeX to ConTeXt
by Brooks Moses 07 Aug '04

07 Aug '04

First, by way of introduction: I've been using LaTeX for about five years now, but am quite new to ConTeXt. I'm a grad student in mechanical engineering, so my primary uses of ConTeXt in the near future are likely to be for my thesis and associated presentations, all of which will likely have lots of complicated equations in them. After looking at what documentation is available for this, I think I have a fair handle on the basics of including math in ConTeXt. However, I do have some questions about things beyond the basics that I use rather frequently, and I haven't been able to find useful answers in the documentation or the list archives. To begin with, I have the following sets of definitions in my standard LaTeX preamble. I know that \newcommand and \renewcommand are LaTeX-specific; what's the appropriate ConTeXt equivalent? Also, do \hat, \vec, and \overline work as I would expect? And is there a direct equivalent to \boldsymbol from the amsmath package? (I need something that will handle both roman and greek letters.) \renewcommand{\vec}[1]{{\boldsymbol{#1}}} \renewcommand{\hatn}{\hat{\vec{n}}} \newcommand{\filter}[1]{\overline{#1}} Also, many of these equations run over multiple lines using the macros from the amsmath package (the "split" environment in particular, but also the "align" environment), and I haven't been able to find much documentation on how to do this in ConTeXt. For an example of the sorts of things I end up doing: \begin{equation} \begin{split} \lefteqn{ \frac{\partial (\rho (\phi u)_j)}{\partial t} + \nabla_k (\rho (\phi u)_k u_j) }\quad\quad \\ = &\; -\nabla_j (\phi p) + \nabla_j (\lambda \nabla_k (\phi u_k)) + \nabla_k \left[\mu \left( \nabla_k (\phi u)_j + (\nabla_j (\phi u)_k) \right) \right] \\&\; {} - \lambda (\nabla_j u_k) \nabla_k \phi - \mu (\nabla_k \phi) \nabla_k u_j - \mu (\nabla_k u_k) \nabla \phi_j - \tau_{\text{surface, $jk$}} \nabla_k \phi \end{split} \end{equation} Looking at that reminds me that I also rather heavily use the \text command from amsmath as well, and rely on its ability to properly size things in subscripts and such. Does this (or an analogue) exist in ConTeXt? Any suggestions? I'd like to be able to simply cut and paste the equations like this one from my LaTeX documents into my ConTeXt documents with as little editing as possible (so that I can maintain consistency between documents in each format), but anything that produces the same output would be good to know about. Thanks much! - Brooks

Unfortunately I don't think ConTeXt includes this feature. But I will cross post to the ConTeXt list to see. Nigel

Hi Hans! I'm using the flow chart module and I want to know how to create a new cell shape using MetaPost and assign that new shape to a shape number. Could you give me an example? Thanks.
