Why don't I see capitals in the following example? \setupbodyfont [cmr,12pt] \starttext \startbuffer[test] The quick brown fox jumps over the lazy dog. \stopbuffer \getbuffer[test] \CAP{\getbuffer[test]} \stoptext

Blank figure hack: is there a better way?
by Brooks Moses 10 Aug '04

10 Aug '04

I'm doing a document which has a large logo in the upper right corner of the page. The logo (which is on a background layer) intrudes into the text area by a small amount, and so it would be nice to have the text wrap around it rather than having to do the wrapping by manual spacers and line-breaks. The "obvious" solution that I came up with for this is to put a blank right-aligned float at the top of each page (it's a presentation where all the page breaks are hand-coded, so that's easy to do), of about the size of the part of the logo that intrudes into the text. I defined a class of floats just for this: \definefloat[logospacer][logospacer] (Using the same name for the singular and plural was a hack to get around the fact that the manual doesn't indicate which of the two the \setupfloat command uses. Which is it?) So far, so good. Except that it's exceptionally hard to _get_ a blank float in ConTeXt, particularly one of a specified size. If I do this (and specify the size in a \setupfloat command): \placelogospacer[right, force]{none}{} I get a nice float exactly the size I want, but with a frame around it and the word "undefined" in the middle. If I put something in the float -- say, a letter, or a non-breaking space: \placelogospacer[right, force]{none}{~} The float suddenly becomes \textwidth wide, which is of course all wrong, but at least I have a blank float that's not undefined. If I put an \hbox in the float, with a fixed width, it stops stretching to fill the pagewidth, but unless I put something that actually makes a mark on the page, it still comes up with "undefined". (The "~" that worked earlier doesn't work if it's in an \hbox.) I tried a number of tricks -- hiding the nothing in a macro, using a zero-height rule, and so forth -- and ConTeXt was sufficiently clever to see through them all. There's also the annoyance that I have to specify the size of the float by the size of the \hbox, rather than in a convenient [width=...,height=...] fashion. Eventually, what I came up with was putting the mark somewhere off the page, with the following command: \placelogospacer[right, force]{none}{\hbox to 1cm{\hskip 5cm x}} This of course gives "overfull \hbox" errors, and is a really ugly hack, but the results are acceptable -- a float of size 1cm by 1 x-height, which doesn't put marks on the physical page. How can I do this better? Better yet, how can I do this properly? Thanks, - Brooks

The last line
by Steffen Wolfrum 10 Aug '04

10 Aug '04

Hi, as far as I know TeX has some internal rules (and penalties) for judging where to hyphenate words or not in order to keep a paragraph not too densed and not too loose. Some rules can be modified by commands like tolerance, spaceskip, emergencystretch et al. Now, I want to have control over the last line. I would like to avoid syllables smaller than (for example) 4 letters being the only element in a paragraphs last line. Like this: xxxx xx xxxxx xxxx xx xxx xxxxxxx xx- xxx. Is there a way to make a kind of global definition for this for the entire document? Thanks for any hints, Steffen

Input path with spaces
by Giuseppe Bilotta 09 Aug '04

09 Aug '04

Hello, I just found out that I cannot compile ConTeXt documents using TeXexec 4.3 when the input path of the original document contains spaces, at least on MiKTeX 2.4 with pdf-e-TeX 1.20a-rc4. -- Giuseppe "Oblomov" Bilotta

updates
by Hans Hagen 09 Aug '04

09 Aug '04

Hi, Later this week i will post an update. Among the things to keep an eye on are: - if you use the new (web2c) beta binaries be aware of the suffixes of formats now all being 'fmt'; conforming to the new tds structure, this should go in sync with a so called $engine subpath under webc, but this wil lnot be supported by tetex (i'm not sure about texlive); this can be rather annoying when you use pdfetex as well as aleph; in that case you may want to try texexec --make --alone --all --engine (i always use --all to get all patterns in the format) - with new binaries you should also be aware of changes in enc and map paths; texfont is already adapted to that and textools can be used to adapt your trees - however, the main reason for writing this mail is that i recently found out that there has been a change in the us hyphenation files; on your system this may be obscured by the fact that sometimes there is an alias file somewhere in the tree mapping old names on new names [fyi: i finally found out that this alias file is also the reason why sometimes fonts like dingbats get messed up]. I have adapted context to look for new and old files; unfortunately important changes like this are not announced and just happen (i wonder how many us-english users are aware of this change); i have been bitten by this (unannounced changes in filenames, and i cross my fingers that the content is the same) too often now; when it happens again, i'll start distributing patterns as in the first versions of context (lang-*.pat/hyp files) - 8 bit in/output: it looks like tex live will not be 8 bit (the last version was 8 bit except chars<32, the previous version was 8 bit) and the next version will be yet another mix; since i want context to be 8 in/8 out the formats will be built with the natural.tcx vector (in a few years, when i can be sure that suers are in sync, i will use the -8bit switch). I will not bore you with teh arguments that are used to let tex not be 8 but by default, but it has to do with unix and terminal output and locales and such. (interestingly this is no real problem for context since the control characters (<32) are mostly used for file io, verbatim, pdf, metapost, javascript, xml etc).

MikTeX 2.4 and Fonts
by DieterJakob＠t-online.de 09 Aug '04

09 Aug '04

Dear Hans, Silly Questions: I use MikTeX 2.4 and there are some ConTeXt Demos underneath texmf/doc/context/demos. If I try to process the File: "d-en-005.tex" the Statement \setupbodyfont[pos] makes trouble; for PDF-Output. The Fonts in your Documentation looks so nice; I'm looking for a nice Serif Font e.g. Palationo. Unfortunately the documentation about Fonts, I can't put into practice. Can you help me to get the Adobe Fonts for PDF up and running? Best Regards Dieter

rectangle-words (like in details.pdf)
by Steffen Wolfrum 09 Aug '04

09 Aug '04

Hi, maybe it's a trivial question: How do I get these black rectangle-words as they are used in Hans' "details.pdf" for example (see page 16 or 25)? Is this a special font - or is there a certain context command used? Thank you, Steffen

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
