Hi,

in the latest beta (211.04.13), the cdots in the following, display as a blank:

\starttext
foo $x \cdots y$ bar.
\stoptext

ldots, however, work fine.

Hi,

in the following document,

\starttext
foo $a \longrightarrow_\sigma b$ bar.

Hi all,

just as a followup and for the mailing list archives, the solution is
to use both Aditya's suggestion to turn on \donknuthmode, as well
replacing the  signs with their interpretations, namely
\pgfmatrixnextcell. Thank you Aditya for the suggestion.

[NTG-context] Latest betas break tikz matrix

2011-02-22 Thread Mathieu Boespflug
Hi all,

This code used to compile in versions of context prior to January,
though I can't quite pin down the versions.

\usemodule[t-tikz]
\usetikzlibrary{matrix}

\starttext
\tikzstyle{description}=[fill=white,inner sep=2pt]
\starttikzpicture
\matrix(m)[matrix of math nodes,
  row sep=3em, column sep=3em,
  text height=1.5ex, text depth=0.25ex]
   {xy\\
 zu\\};
\path[-]
  (m-1-1) edge node[description] {$*$} (m-1-2)
  edge node[description] {$*$} (m-2-1)
  (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
  (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\stoptikzpicture
\stoptext

(compilation error at the bottom of this email)

I thought at first that this was a luatex problem, but I've ruled that
out with the following plain tex file, which compiles just fine in
plain luatex and in plain pdftex:

\input tikz.tex
\usetikzlibrary{matrix}

\tikzstyle{description}=[fill=white,inner sep=2pt]
\tikzpicture
\matrix(m)[matrix of math nodes,
  row sep=3em, column sep=3em,
  text height=1.5ex, text depth=0.25ex]
   {xy\\
 zu\\};
\path[-]
  (m-1-1) edge node[description] {$*$} (m-1-2)
  edge node[description] {$*$} (m-2-1)
  (m-1-2) edge[dashed] node[description] {$*$} (m-2-2)
  (m-2-1) edge[dashed] node[description] {$*$} (m-2-2);
\endtikzpicture
\end


I have no idea what the error is telling me and what could be causing
it. Any ideas?

Many thanks,

Mathieu

Re: [NTG-context] Bad interaction between new interpretation of underscore and modules

2011-01-14 Thread Mathieu Boespflug
Thank you for the solution, Wolfgang.  But it seems rather painful to
have to replace every occurrence of _ in my definitions module with
the very verbose \normalsubscript just because it's a module. The new
default catcode for _ introduces extra difficulty when defining math
macros. Would it be possible to at least have a macro to revert to the
old behaviour? Also, I'm still stumped as to why modules make any
difference here. I would have expected this problem to also show up if
the definitions were made inline at the top of the source file for the
document.

All the best,

Mathieu

 Hi all,

 today's beta introduced a really strange problem. Consider two source files:

 This results in the following compile error:

 However, if you change \usemodule[definitions] into \input

 is that the underscore is a valid character for macro names now
 outside of math mode, which is what is causing the problem. But I
 really don't understand what magic is going on in the modules code to
 trigger this.

 I would be very interested in an explanation of what is going on.

 You need \normalsubscript in your module. You define a command and
 in this case it doesn’t matter that you plan to use it in math mode,
 the _ is now a normal letter like “a” and this won’t change when you
 call \lambdax in your document.

 Write

  \def\lambdax{\lambda\normalsubscript x}

 and it will work again.

 When you write a module you put \unprotect and \protect at the begin and
 end of the file because they make @, !, ? and _ to a normal letter like abc
 which can be used in macros. When you load a file with \usemodule or
 \environment this isn’t necessary because context adds already calls
 both commands when the file is opened and closed for reading and this
 mechanism is used even if you aren’t aware of this.

 PS  For \environment this is only true when you use it in a document
 with \starttext or when you write it before \startproduct, \startcomponent 
 etc.

 PPS  You can abuse \nonknuthmode to make your module to work

 \startbuffer[definitions]
 \pushcatcodes\nonknuthmode % \startnonknuthmode
 \def\lambdax{\lambda_x}
 \popcatcodes               % \stopnonknuthmode
 \stopbuffer

 \savebuffer[definitions][p-definitions.tex]

 \startbuffer[more]
 \def\morex{\more_x}
 \stopbuffer

 \savebuffer[more][p-more.tex]

 \usemodule[definitions,more]

 \starttext
 blah $\lambdax$ blah. \morex

 It's related to \Umathradicalrule* not being set. This has never been the
 case but at some point it worked ok and Taco/I are not going think too long
 about when and where something changed along the route. I'll make a new

Re: [NTG-context] Skew not working in latest beta

It seems this is a regression of either ConTeXt or LuaTeX. I have a
PDF that I generated on December 9th that doesn't have this problem.
According to the PDF metadata, the versions used to create it were:

Producer: LuaTeX-0.64.0
Creator: ConTeXt - 2010.11.27 14:27

I also have a PDF from the same source created end of December with
the following versions, that features the bug:

ConTEXt version 2010.12.21 10 :50 on LuaTeX version 0.65.0.

Could it be a LuaTeX 0.65 regression?

Hi all,

consider the following document:

\starttext

{\definedfont[Regular at 30pt] blah\footnote{hello}}

\stoptext

and compare it with the result for the same document where the first
line is commented out. The footnote number isn't aligned the same.
Shouldn't setupinteraction have no impact this sort of thing?

Re: [NTG-context] Bibliography contains references not cited in the text

2010-11-29 Thread Mathieu Boespflug
 No, indeed they were not sorted. But I saw that the the .bbl file was
 sorted. I then found that when you add sorttype=bbl as an argument to
 \setuppublications  (so, in your example use
 \setuppublications[refcommand=authoryear,sorttype=bbl]) and use
 \placepublications[] you will get the cited publications sorted
 alphabetically by author name.

 I later saw that this solution was already given by Aditya Mahajan in
 ntg-context Digest, Vol 76, Issue 141   Date:   29 oktober 2010, Message
 4, Subject:  sorttype for bibtex

 On top of that, this is also documented in the bib module's manual.

Except that doesn't seem to work with the bibliography being placed
using \placepublications in its own chapter in the backmatter. A
similar issue was reported in 2006

http://www.mail-archive.com/ntg-context@ntg.nl/msg15442.html

but the solution given then involved writing \placepublications[criterium=all].

 Here's a minimal example. bib file attached. In my real thesis

[NTG-context] \underbrace broken in latest beta

2010-11-27 Thread Mathieu Boespflug
Hi,

I upgraded to latest beta and something that used to work before
doesn't anymore. Here's a minimal example:

\starttext

Here's an underbrace :
\startformula
\underbrace{X \cdots X}_{n \text{ times}}
\stopformula
\stoptext

The error I get is:

! Missing number, treated as zero.
to be read again
   b
\Umathbotaccent -\Umathaccent b
ottom
\normalunderbrace -\Umathbotaccent
0 0 23DF
\mathopwithlimits #1#2-\mathop {#1
   {#2}}\limits
l.5 \underbrace{X \cdots X}
   _{n \text{ times}}

All the best,

Mathieu

Hi Hans,

thank you for the quick response. Unfortunately, your fix below
doesn't seem to work. Or perhaps I need to regenerate some files? I
ran context --generate and context --make after your instructions but
I still get the same error. My context version is:

ConTeXt  ver: 2010.11.27 14:27 MKIV  fmt: 2010.11.27  int: english/english

Thanks,

Mathieu

Re: [NTG-context] Bibliography contains references not cited in the text

2010-11-26 Thread Mathieu Boespflug
Hi,

 I am having trouble with the bib module. The bibliography section of
 my article contains references that I have not cited in the text.
 These are in my .bib file, but it seems to me that references that
 were not cited in the text were ignored when constructing the
 bibliography.

 Hi,
 When you add

 \nocite[Aucremanne2005]
 \nocite[Fabiani2007]


 before \section{References}
 these non cited publications will show up in your bibliography. (At
 least it does here with Minimals of 24 november)

... which is the way it should be, no? The problem of the original
poster is that these entries should not appear in the bibliography
despite being in the .bib file, because they aren't mentionned at all
in the main text.

I can confirm this issue. I have run into myself in typesetting my thesis.

Taco, if it can help you track down the bug, IIRC, this problem
appeared sometime around beginning of October, though the bib module
of previous versions of mkIV had other bugs that made it unusable
(such as sorting by author not working).

Also, there is another bug in the bib module, which i find very
strange. If we augment the OP's .bib file with two more entries, and
cite those, then one of them does *not* appear in the bibliography
despite being cited. It also creates a big blank in the bibliography.
Here's a minimal example. bib file attached. In my real thesis
bibliography (over 200 entries), there are several such entries
missing and several big blanks of varying sizes in the Bibliography
section.

Regards,

Mathieu

 Hi,

 This is to announce an alpha release of the visual counter module. See
 http://randomdeterminism.wordpress.com/2010/11/14/visualcounter-module/ for
 some examples, in particular
 http://randomdeterminism.files.wordpress.com/2010/11/theorem.pdf

 The idea is to display a counter visually, in the same spirit as
 interactions bars. There is no support for interaction, but, on the plus
 sides, these work for any conter, not just the page counter. The idea of the
 module comes from the counters designed by Thomas as part of the
 simpleslides module.

 The module only works with MkIV because I am using the new namespace code.
 So MkII support is unlikely.

 Anyone else interested in such counters?

[NTG-context] Grabbing first letter of a sentence

2010-11-15 Thread Mathieu Boespflug
Hi,

I'd like to get access to the first letter of a chapter for the
purpose of laying out the chapter heading, but I'm having difficulty
with expansion.

Here's my attempt:

\def\MyChapterTitle#1#2{%
  \def\doMyChapterTitle##1##2^{%
  {\tfb ##1}##2
  }
  #1 \doMyChapterTitle#2^
}

setuphead[chapter][command=\MyChapterTitle]

\starttext

\chapter{Foo}

bar

\stoptext

This doesn't work because the chapter title isn't expanded out before
passing it to \MyChapterTitle. I know there is deeptextcommand but I
need the chapter title during the layout of chapter number + title, so
I need to use command instead of deeptextcommand. I attempted to get
hold of the chapter title using the following

\def\MyChapterTitle#1#2{%
  \def\doMyChapterTitle##1##2^{%
  {\tfb ##1}##2
  }
  #1 \expandafter\doMyChapterTitle\expandafter{\fetchmark[chapter][first]}^
}

but that doesn't seem to work either. Any ideas?

Many thanks,

M

Re: [NTG-context] A few puzzling problems (bugs?) with enumerations

2010-10-15 Thread Mathieu Boespflug
Ok so after reading the source code of strc-des.mkiv, I found that
contrary to earlier documentation such as

http://www.ntg.nl/maps/36/09.pdf

it is not the 'number' parameter that should be used to share
numbering but the 'counter' parameter. After fixing that in my code,
theorems now have proper numbers and references to theorems work
properly too. However,

\starttheorem[number=no]
  blah
\stoptheorem

and

\starttheorem[-]
  blih
\stoptheorem

still don't work as expected inside sections, and I still have problem
1 listed in one of my previous emails, namely


Any ideas?

On a sidenote, I would like to contribute to the wiki or whatever is
the main documentation source of the ConTeXt project something to
document those parameters that are specific de \setupenumerations. The
context reference manual and the wiki both just refer to
\setupdescriptions yet there are a number of parameters that don't
exist for \setupdescriptions, such as number, counter, prefix,
prefixcomponents, etc.

Many thanks,

 behaviour?

 2. I want the theorem enumeration to share its number with the

 section, the theorem just doesn't have any number. Inside a section,
 the theorem very oddly displays the section number.

 3. I want the proof enumeration to have no number.  That doesn't
 work inside a section. As for the theorem enumeration, the section
 number is printed even though here i requested no number at all!

 4. Suppressing the number for a specific enumeration using the [-]
 switch doesn't work. As before, inside a section, the section number
 appears instead of no number.

 5. Citing a specific theorem using \in{theorem}[thm:pnp] doesn't show

 I'm guessing the last four points are all related.

Wow, thank you very much for your fix, Wolfgang! I can confirm that it
works. I hope this fix makes it into the next beta?

Abount documenting these extra parameters that \setupenumerations has
over \setupdefinitions, I figure that I should contribute that to the
wiki. But I wonder, how does this kind of user generated documentation
on the wiki get synchronized with the ConTeXt Reference manual hosted
at Supelec?

 the arrows available in CM is, but it's a start.

 \longleftarrow

 \swarrow

 The above arrows are all available now (except that the long arrows have
 no special versions for script sizes, I don't no if it is really
 needed).

[NTG-context] Euler font and context minimals

2010-09-25 Thread Mathieu Boespflug
Hi everyone,

I'm using ConTeXt for my PhD thesis and as I'm getting sick of writing
up I've been trying to tweak the appearance a bit. I'd like to switch
to using Palatino font for main body and Euler font for math. So I
tried

\setupbodyfont[pagella-euler]

\starttext


test $f(x) = x^2$.

\stoptext

But I get errors during processing such as:

MTXrun | run 1: luatex

I noticed that in my (recent) ConTeXt minimals tree, there was no
euler.odf, so I grabbed one from somewhere in the tree in
http://minimals.contextgarden.net/minimals/current, and placed it
$CONTEXTROOT/tex/texmf-fonts, but to no avail. I still get the same
error messages. I also ran luatools --generate and that doesn't make a
difference. I read through the typography and fonts chapters of the
manual but I didn't find specific information about installing fonts.
Am I doing it right? How can I get ConTeXt to recognize this standard
font?

Many thanks,

Mathieu

Re: [NTG-context] Euler font and context minimals

2010-09-25 Thread Mathieu Boespflug
Hi Wolfgang,

thanks for the tip! It works now. I searched all  over the wiki to see
if this is documented anywhere. It isn't so far as I can see. I can
add a section to the Fonts page on the wiki, but shouldn't this
information go in the manual instead?

Also, I still have a problem: many types of arrows don't show up
properly in the euler font. For example as in below:

\setupbodyfont[palatino]

\starttext
test $x \mapsto x^2$.

test $a \longrightarrow b$.

\switchtobodyfont[pagella-euler]

test $x \mapsto x^2$.

test $a \longrightarrow b$.

\stoptext

Best regards,

Mathieu

 The correct path for the font is $CONTEXTROOT/tex/texmf-fonts/fonts/data
