math fonts

math fonts

[Albrecht Kauffmann]

Hi all,

I am faced with a problem with fonts in formulas, when the bodyfont is
8-bit-encoded:

\setupoutput[pdftex]
\setupbodyfont [aer,10pt] 
\starttext
$ \Gamma \Delta \Theta$ 
\stoptext

With other 8-bit-fonts like e.g. lbr I get the same result: `'^
Only with cmr as bodyfont I get the right characters. But with cmr arise
problems with the hypenation in german language.

Can somebody give me a hint?

With many thanks in progress
Albrecht

Hm. These are positioned in the lower part of as the crm fonts. And, since
[out of lazyness] the aer fonts def uses the cmr ones by remapping the
names, the ec encoded cmr* fonts are not that suites for math. Sigh. But,
since there is some machinery for independent math fonts, we can redefine
that part. But, since cmr10 is now aer10, we have to make sure that we
bypass the mapper, which can be done [hack hack hack] with a space in front. 

% hack to prevent mapping of filenames, watch the space! 

\definebodyfont [12pt] [mm] [mr= cmr12]
\definebodyfont [11pt] [mm] [mr= cmr10 at 11pt]
\definebodyfont [10pt] [mm] [mr= cmr10]
\definebodyfont  [9pt] [mm] [mr= cmr9]
\definebodyfont  [8pt] [mm] [mr= cmr8]
\definebodyfont  [7pt] [mm] [mr= cmr7]
\definebodyfont  [6pt] [mm] [mr= cmr6]
\definebodyfont  [5pt] [mm] [mr= cmr5]
\definebodyfont  [4pt] [mm] [mr= cmr5]

\definebodyfont [14.4pt,17.3pt,20.7pt] [mm] [mr= cmr12 sa 1]

Later this year those symbols will be mappen in other ways anyway. 

Either add these lines at the end of font-aer or better at the end of
font-cmr and regenerate the format. 

If you want to default to aer: 

texexec --make --bodyfont=aer

will embed these defs

Hans, 

I think the mapper comes into action too late. It makes much more sense
to do the binding to mapped names at an earlier stage (somewhere inside
definebodyfont). That would prevent this weird hack.

Make sure you do the \definebodyfonts *before* the call to
\setupbodyfont, or there will not be any change.

This line doesnt work. 'sa' is not low-level enough and ends up 
being typeset. You need three separate lines using 'at' instead:

\definebodyfont [14.4pt] [mm] [mr= cmr12 at 14.4pt]
\definebodyfont [17.3pt] [mm] [mr= cmr12 sa 17.3pt]
\definebodyfont [20.7pt] [mm] [mr= cmr12 sa 20.7pt]

Greetings, 

Taco

hm. the problem is that it is fully recursive, so it needs some deep
non-recursive thinking

oeps. thanks for testing

combined header texts

[Albrecht Kauffmann]

Hi all,

can someone, please,  give me advice how to create headertexts, which
should to content the chapternumber, the sectionnumber and the section?
That is, e.g. "1.1 Einführung".

With many thanks in progress
Albrecht

Here an example:

\setupfooter
   [style=\sl]

\setupheader
   [style=\sl]

\setupheadertexts
   [chapter][section]

\setupfootertexts
   [My document][]

See docs for valid contents of \setupheadertexts and \setupfootertexts.

Groetjes,

Berend. (-:

You can also explicitly ask for a marking, 

\setupheadertexts
  [{\getmarking[sectionnumber}\quad{\getmarking[section]}]
  []

an optional second arg let you specify what specific mark you want 

\getmarking[section][first last previous both all]
