bug in mp
by Hans Hagen 29 Aug '04

29 Aug '04

Hi, I'm currently translating all commands in the sources to english; for that i use metafun as test file. In the process I ran into a metapost fuzziness: var_123456 is not handled ok, since mp scans numbers due to the way it implements arrays. This may result in problems with transparency factors. I made a workaround, but will (can) only upload when i think that the english translations went ok. If you run into problems i can post a metafun fix.

btex ... etex in .mp
by Nikolai Weibull 27 Aug '04

27 Aug '04

Hi! I remember reading somewhere that you can't use btex ... etex in "input" .mp files, as there is no possibility for them to be processed at that time. I've hit a snag, though, and this would really be a good thing for me to have. Is there any way to get similar behavior? Basically, I want to define some stuff that I want to reuse in several pictures. 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);}

ConTeXt and XML: entities and attributes
by Michael Guravage 27 Aug '04

27 Aug '04

I have two questions, both concerning typesetting XML with conTeXt. The first questioin is about how ConTeXt handles entity declarations and reference. The following bit of XML declares and references four parameter entities. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE TEI.2 PUBLIC "-//TEI P4//ELEMENTS TEI Lite XML ver. 1//EN" "http://www.tei-c.org/Lite/DTD/teixlite.dtd"[ <!ENTITY % ISOlat1 SYSTEM 'http://www.tei-c.org/Entity_Sets/Unicode/iso-lat1.ent'> %ISOlat1; <!ENTITY % ISOlat2 SYSTEM 'http://www.tei-c.org/Entity_Sets/Unicode/iso-lat2.ent'> %ISOlat2; <!ENTITY % ISOnum SYSTEM 'http://www.tei-c.org/Entity_Sets/Unicode/iso-num.ent'> %ISOnum; <!ENTITY % ISOpub SYSTEM 'http://www.tei-c.org/Entity_Sets/Unicode/iso-pub.ent'> %ISOpub; <!ENTITY moe SYSTEM 'moe.xml'> ]> ConTeXt does not typeset the declarations, but does typeset the references, i.e. the first line in the typeset result is: %ISOlat1;%ISOlat2;%ISOnum;%ISOpub; Has anyone seen this before, and has anyone an opinion how it should be fixed? My second question concerns tag attributes. The following bit of XML code contains two catRef tags, each with two attributes: <profileDesc> <textClass> <catRef scheme="period" target="early"/> <catRef scheme="Stooges" target="Moe Larry Curly"/> </textClass> </profileDesc> Can someone please suggest how I can process these and grab scheme and target attributes so that the final typeset result looks something like this: Period: early Stooges: Moe, Larry, Curly Thanks in advance for your help. Cheers, Michael Guravage guravage(a)operamail.com PS: The attatched file contains an example.

concatenate PDF files.
by Paulo Ney de Souza 27 Aug '04

27 Aug '04

I am looking for a way to concatenate several PDF files, and found this e-mail from Hans: http://www.tug.org/pipermail/pdftex/2001-January/000240.html saying that "texexec" can do it in several ways! and to look on the web-site, texexec manual and the mailing list for directions. I went to the manual first and found only ONE: texexec --pdfarrange --noduplex --paper=S6 file-a file-b but that nullified all links I had in my files, and changed the opening from from FitVisible to something else (all files were FitVisible). Next I went to two other sources he mentioned and Googled for: "-ntg-context concatenate pdf" did not yield much beyond that, and neither did Googling http://www.pragma-ade.com/ for the words "concatenate" or "combine". So does anyne know how to use "texexec" to concatenate two PDF files and preseve as much of the file as possible (links, opening format, ...) ? Paulo Ney

Columnset Areas - Background Color ?
by Miguel Queiros 27 Aug '04

27 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.

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. A question: is it intentional that the array environment in t-amsl > produces notably different spacing than LaTeX's array environment? 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!)
by Steffen Wolfrum 25 Aug '04

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.
