Columnset Areas - Background Color ?
by Miguel Queiros 26 Aug '04

26 Aug '04

Hi ! I've been trying to use columnsets with columnsetareas but I haven't been able to define a background color for the text in the columnset area. You can see the problem in the pdf I've attached (area5.pdf). I'v created a small example of the problem: area5.tex As far as I recall I've also tried to use a columnset span but the problem was the same. Can anyone provide me with some hints so that I can use some background color in columnsetareas ? Thanks, Miguel Queirós

Boldmath Lucida
by Sytse Knypstra 26 Aug '04

26 Aug '04

Hi all, When writing a mathematical text I encountered a few problems with bold symbols. Under the line you will find three problems (dutch interface). Are they due to my insufficient knowledge of installing fonts? Thanks for any comment. Sytse Knypstra ============================================================== \definetypeface [mainface] [rm] [serif] [lucida] [default] [encoding=texnansi] \definetypeface [mainface] [tt] [mono] [lucida] [default] [encoding=texnansi] \definetypeface [mainface] [ss] [sans] [lucida] [default] [encoding=texnansi] \definetypeface [mainface] [mm] [math,bfmath] [lucida] [default] [encoding=texnansi] \stelformulesin [methode=vet] \gebruiktypescript [lucida] [texnansi] \switchtotypeface [lucida] [12pt] \switchnaarkorps[mainface] \usemathcollection[lbr] \stelkorpsin[mainface] \starttekst Problem 1: ${\bfmath x}$ gives boldface standard x. ${\bfmath x}{\bfm }$ gives boldface italic $x$ which is what I want. ${\bfmath \Gamma}$ gives a space; only ${\bfmath \Gamma}{\bfm }$ gives the boldface italic $\Gamma$ that I want. Problem 2: ${{\bfm \beta}}$ gives a wrong glyph (in fact the ligature 'fi'). Problem 3: After $\bfm \beta$ the text is no longer printed in the same Lucida Bright style as before. \stoptekst

That's not the problem. Don't forget that I just posted a minimal example to show the generel effect as also seen by Willi. In my documents the figures are different of course: the footnote size is smaller, the margin space higher etc. So it's not the problem that the footnotes don't fit. It's more that they are *still below* the text as before - now as empty space. (You can easily make the test: Take a regular document with footnotes per page below the text. Then use the code to get the footnotes in the margin. You will see that the body text doesn't change at all. It's just the notes moving and leaving empty space behind) Steffen

Re: Some proposed improvements for t-amsl.tex.

Hello Moses (uh ... I hope that's the name and Brooks is the surname ... :)), thank you very much for your email; it's very detailed and useful, which is why I've only replied this late (well, also because vacation-style RL popped in, but I digress :)) I'll address a couple of points replying under the relevant text. Monday, August 2, 2004 Brooks Moses wrote: > This inconvenience happens to show up in t-amsl.tex's "align" and "gather" > implementations, which is one place where I really need that compatibility > function.

Stop #1. I *enormously* love this idea. Have you been running test cases with this code instead of the one in t-amsl?

The only thing I would fix is that instead of the fixed 0pt and 4pt I would set up some \dimens (\intersomethingspacing or so). What do you think? And again, if you have actually been using this code instead of the one in t-amsl, I'll be happy to add it. > Also, a similar method can be used to replicate the split environment > (which, unlike the above, should go inside an explicit \startformula and > \stopformula pair).

Yeah, equation numbering in ConTeXt is something which I left "for another day" myself (I need it for the nath package as well). > P.S.

No, it's simply due to the fact that I haven't even bother to check if it were or not, because I didn't care either way :) The parameters are there. We'd only have to check how to use it within the ConTeXt spacing framework. -- Giuseppe "Oblomov" Bilotta

Re: Footnotes in margin? (HELP!)

Hi Willi, that's also what I experienced: the code works with very small footnotes. I am working now on a thesis with kind of normal equipment: Some hundred pages, about 900 footnotes with lots of them quite long (seems to be normal nowadays for art-historians). So what to do?

nath problems and patches
by Christopher Creutzig 25 Aug '04

25 Aug '04

Giuseppe, you may or may not know about these problems already, so I decided to simply send them all. I'm using t-nath.tex 2003.12.08, updated five minutes ago from www.tug.org, ConTeXt 2004.6.26, and pdfeTeX 3.14159-1.10b-2.1 (Web2C 7.4.5). nath seems to have trouble with $$...$$-formulas. This file won't compile: \usemodule[nath] \starttext \placeformula $$a$$ \stoptext Error message: Runaway argument? \@@dollar {\to \asciiB \ExpandBothAfter \doifincsnameelse \asciiA \asciiB \ETC. ! File ended while scanning use of \convertargument. Replacing $$...$$ by \startformula...\stopformula fixes this, but the following file won't compile either: \usemodule[nath] \starttext \placeformula \startformula \sum_{i=0}^m a_i\stopformula \stoptext The culprit, it seems, is that \inlinemath uses \xdef, but \mathop@@@ puts unexpandable code into the argument of ^ and _. The following hackery seems to work: \def\mathop@@@{% \ifsp@ ^{\hbox{\edef\noexpand\!!stringa% {\noexpand\noexpand\noexpand\imath@{\the\sp@toks}}% \def\noexpand\\{,\ }\noexpand\!!stringa}} \fi \ifsb@ _{\hbox{\edef\noexpand\!!stringa% {\noexpand\noexpand\noexpand\imath@{\the\sb@toks}}% \def\noexpand\\{,\ }\noexpand\!!stringa}} \fi} Though I must confess I don't understand why the complexity with introducing \!!stringa is needed. The following version works for me: \def\mathop@@@{% \pushmacro\\ \def\\{\noexpand\text{, }}% \ifsp@ ^{\the\sp@toks}% \fi \ifsb@ _{\the\sb@toks}% \fi \popmacro\\} Parentheses in display formulas don't work: \usemodule[nath] \starttext \startformula (x) \stopformula \stoptext I don't know if at some time ConTeXt placed \the\everymath inside \everydisplay, but with the current ConTeXt, you need to \appendtoks to both. I regard the output as broken, but at least it will compile. Another bug: t-nath.tex defines \savecatcode and \restorecatcode, but these names have already been used in verb-ini.tex. I have locally replaced these with \nath!savecatcode and \nath!restorecatcode, seems to work. A math problem not related to nath: \starttext \setupformulae[align=left] \startformula \eqalignno{a&=b\cr c&=d} \stopformula \stoptext doesn't work for me. Anyone else? Regards, Christopher Creutzig PS: I won't be able to read mails in the next four weeks.

Hans, I don't know what crazy stuff Idris is using this footnotes for, but for my case it went absolutely horrible: Almost every page gets half empty!! It looks like the footnotes are just moved to the margin - leaving empty space, without the body text comes flush bottom again. I'm sure my publisher won't be amused about all this empty paper... It tried to send a minimal example and changed just the text between \starttext and \stoptext. Maybe there is something that could be changed in order to get the main text in flush bottom shape again AND keep the corresponding footnotes in the margin?

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);}

Announcing a new script: TeXVersion
by Taco Hoekwater 25 Aug '04

25 Aug '04

Hi, Sometimes I find it quite hard to discover what version of TeX + ConTeXt I am actually running. As an aid in debugging problems, I have created a Perl script that attempts to collect all relevant version information and prints it to the screen in an organized manner. Running it will generate output like this: TeXVersion 0.1 / Taco Hoekwater 2004 texexec : TeXExec 4.4 - ConTeXt / PRAGMA ADE 1997-2004 texutil : TeXUtil 7.4 - ConTeXt / PRAGMA ADE 1992-2002 tex : pdfeTeX, 3.14159-1.10b-2.1 (Web2C 7.4.5) context : ver: 2004.8.15 cont-en : ver: 2003.1.31 fmt: 2004.6.19 mes: english If you are interested, you can download the script from http://tex.aanhet.net/context/scripts/ This functionality will eventually become part of texexec. -- groeten, Taco
