bug with active :!;?

bug with active :!;?

[Olivier]

Hi,

Seems like the following crashes conTeXt:

 \useencoding [ffr] 
 \mainlanguage[fr]

 \setupheadertexts[text][][][\setups{run:left}][]
 \startsetups run:left
         nothing
 \stopsetups

 \starttext
        Nothing special here
 \stoptext

Of course one can live with this by renaming the tag.
However, the bug will also occur in the 
  \cite[Bob:A,Bob:B]
commands from the bib module, and I assume in anything that deals with
csnameS containing active colons...

Strangely enough, the bug doesn't seem to occur in
  \placeformula[eq:A]

Many thanks for hinting a fix,
Olivier

With the next pdftex we will not need this active mess any more since pre-char spacing will be supported natively; by that time we need to adapt the ffr files

This is a good news indeed. 
By the way, does this include the possibility to treat the character in
different ways depending on the current mode (math/text)?
Because, in the current setting, if you request for 3cm before `:' and
then define a mathematical function $f : R \to Z$ you'll end up with a
huuuge space between f and : which you certainly isn't what you want.

Thanks for your answer,
Olivier


PS:  Also the default definition in useencoding is .25em for :;?!
I'm no typographical expert at all but I thought the standard is
indeed .25em for ;?! but a normal space before `:'

remind me in a few days; it's easy to fix with some extra's in \everymath

see attached file; taco may know other tricks (i remember that there is some mechanism in tex for active char treatment in math mode)

It is possible to treat an arbitrary character as if it was \active
inside math mode, but not the other way around: when a character has
catcode \active, it is always treated as that macro, regardless of
the current mode.

For curious people, here is how you make a "mathmode only" macro:

   \mathcode`\!="8000
   \begingroup
   \catcode`\!=13
   \gdef!{\it math}
   \endgroup
   This is a $!$ test!.

Cheers, Taco

Setting header texts

[Jilani Khaldi]

Hi All,

Having set this header text:

\setupheadertexts
[\vbox{\hbox{AAA}}
\hbox{BBB}}}]
[{CCC}]

the result is:
AAA in the top left corner,
BBB just under AAA
CCC in the top right corner
with the page number in the center

What I want to have is:
1. AAA in the top left corner,
2. BBB just under AAA
(and that's ok)

3. CCC in the top right corner but containing the page number
4. Just below all this a long line to separate the page header from its 
content

I have struggled for a while but in vain, so help!

Thanks.

Setting header texts (second)

\getmarking{chapter} etc

I tried to apply the tips but now I have the page number on both the 
center and the right, without having the name of the chapter and the 
section in the left. Could you please be more precise. Where can I find 
info about "\getmarking"?
Thanks.

You already got the answer to this one I guess, just to sum it up:

\setupheadertexts
[{\framed[align=flushleft,frame=off,offset=0pt]{\getmarking[chapter]\crlf\getmarking[section]}}]
[pagenumber] % or empty

% and one of the two commands:
%-----
% this one overwrites the second argument above
%\setuppagenumbering[location={header,right}]
% this one only removes page number from the center
%\setuppagenumbering[location=]

> 4. Just below all this a long line to separate the page header from its

\setupbackgrounds[header][text][frame=off,bottomframe=on]

(You probably have to adjust some parameters in \setuplayout: header
height and distance between header and text.)

Thank you. It works, but I have a long line on all the pages. Is it 
possibile to exclude the first page of the document and the first page 
of every chapter using some settings?

Re: Setting header texts (second)

Hi.

"\getmarking[chapter][current]" should give you the title of the current
chapter. Similarly "\getmarking[section][current]", etc.

In order to rid yourself of the default pagenumber in the middle of the
top header, use "\setuppagenumbering[location=]", or add "location=" to
your existing \setuppagenumbering command.

Hope that helps.
