Two misfeatures in placefigure
by Aditya Mahajan 25 Oct '06

25 Oct '06

Hi, I found two misfeatures in placefigure. 1) with \placefigure[top] the figure can float to the top of the page, even if the page starts a title or a chapter. 2) The paragraph after the figure is indented, even if it comes right after a \section. For example, \setupindenting[medium,yes] \setupfloats[indentnext=no] \starttext \chapter{This is a test} \section{Introduction} \placefigure[top][test] {Sample Figure}{} \input knuth \stoptext Notice that the figure is on the top of the page and the first paragraph of knuth is indented. I could not find any options to turn these features off. I think that (2) is hard to detect, and \noindent before the paragraph is a workaround, but I could not find any work-around for (1) other than moving the \placefigure invocation to somewhere later.

In-line syntax highlighting for type
by Aditya Mahajan 25 Oct '06

25 Oct '06

Hi, How can I define a command that is the inline version of \startTEX ... \stopTEX. (I need to show inline commands in color). There had been a discussion on this in the past, and Taco had suggested a solution http://archive.contextgarden.net/thread/20050907.093522.baf795f5.en.html which is also posted on the wiki. http://wiki.contextgarden.net/Verbatim_text#In-line_text However, due to the recent changes in verbatim code, that solution no longer works. Can anyone suggest how to fix it? Thanks, Aditya

Two problems with current ruby scripts

global layout change from header=none in \setuphead
by Sanjoy Mahajan 25 Oct '06

25 Oct '06

Another of those 'not sure if I'm confused' examples: \setuphead[title][header=none] \starttext \title{Hello} \dorecurse{15}{\input tufte} \stoptext With header=empty, it worked as I expected: The first page had no page number in the header and the other pages had a page number. Then I tried the example above, with its header=none, so that the first page would allocate no space for the header (as well as have no page number). But then no pages, not only the first, allocated the header space. Is there a subtle difference between header=none and header=empty making the first one a global setting but the second one local to the page with the title (the local behavior is what I had wanted)? It's probably a related confusion or bug, but an alternative solution (from <http://www.ntg.nl/pipermail/ntg-context/2005/009180.html>) using \definelayout[1] also produced a global layout change: \definelayout[1][height=7in] \starttext \title{Hello} \dorecurse{15}{\input tufte} \stoptext This is all with ConTeXt ver: 2006.10.24 13:47 (same results on the live context). Any hints appreciated! -Sanjoy

ConTeXt installtion and Debian

25 Oct '06

Hi Taco, hi all! (I am sending personal copies since I don't know whether I can mail to the ntg list). First of all thanks for the explanations! You wrote: > To actually update ConTeXt, assuming you already have a relatively > modern context installed, you say > > # ctxtools --update > > and that fetches the zip file(s) from the pragma site (or a mirror), > unpacks them, and updates the various perl and ruby scripts that come > with ConTeXt. > > You have to be root for this when you want to update the global install, > otherwise you have a few extra caveats, see below. > > After a succesful update, you have to run > > # texexec --make --all [--xetex | --aleph | --pdftex] <formats> > > Where <formats> are the desired formats to run.

I checked the current zip file and the current ctxtools.rb script, it does nothing else than: - download the current zip - unpack - install the stubs from scripts/context/stubs/* - update the formats. So this is what we have to do in the Debian package, too. This is not hard, in fact most parts are already done. The only thing we have to do is create a way for the user to choose which formats should be generated. I will think about this. But for the search pathes, we will adjust the Debian texmf.cnf file, to get different engines loading differen cont-en.fmt files. Thanks.

Re: [NTG-context] how to define a new math symbol
by M.J. Kallen 25 Oct '06

25 Oct '06

Great, it works! Running "texexec --pdf test-prodint" worked immediately, but "xdvi test-prodint.dvi" gave me an error relating to mktexpk not being able to create a bitmap font. Solved this problem by running "updmap --enable Map prodint.map". I don't think I could have done this myself, as I do not understand some of the steps in your solution. Thank you very much!

That last bit of information is crucial, because there is a difference between font handling between CM/Lm and commercial fonts. I've been skyping with Hans and he came up with the code below. You can use the font files from the LaTeX zip, you just have to make sure that pdftex can find the (map) file, of course.

Taco, I'm not sure I understand your question. I'm using TexLive on a linux system. I do not use any other fonts other than CM. The file prodint.afm has the following contents: StartFontMetrics 4.0 Comment This is prodint.afm created from prodint.pfb by t1lib V. 1.0.0.

Another problem with this approach is the fact that this does not define a MATH symbol, which is really what I would want. Based on the LaTeX style file prodint.sty, I'm guessing I'll at least need a command like: \definemathsymbol [prodi] [op] [prodint] ["xx] but I can't figure out the usage of this command. I also suspect that I can not used the prodint.tfm file, supplied with the LaTeX package, but need to run Texfont to create one for ConTeXt. Can you confirm this? I greatly appreciate any help!

Hardcoded options in the Ruby scripts
by Richard Gabriel 25 Oct '06

25 Oct '06

Hello Hans, I'm still wondering why there are certain formats hardcoded in your scripts and how the "make all formats" feature does (not work). See scripts/ruby/base/tex.rb: Lines 131-137: Here are a few languages predefined which texexec "knows". If I want to add a format for another language, I have to add a new line here. Line 339: Here are the "default" TeX formats defined. No problem to consider something as default ;-), but the point is that "texexec --make --all" actually does "make all DEFAULT formats", NOT "make all AVAILABLE formats". :-( Anyway, the main problem I see is altering of a script which comes with the ConTeXt distribution - the changes made into this scripts must be done again and again after each update. My suggestion is: 1. To put the format definition into a separate file (like user.rb or so) which won't be owerwritten in any case. [Note: cont-usr.tex is a good analogy to this] 2. "Make all" should make ALL the defined ConTeXt formats, not the default ones. Thanks, Richard
