Some things I don't understand about typescripts...

Some things I don't understand about typescripts...

[Thomas A. Schmitz]

Christmas is approaching, and I hate to be a pest this time of the  
year, but there's this problem that really bothers me: I'm still  
working hard to release version 2 of my Greek module on the  
unsuspecting masses. It will define all fonts in a typescript instead  
of as single fonts to allow switches like {\em } etc. It appears that  
the typescript mechanism creates some problems. The most serious one  
for me is that it seems to demand a full list of sizes that can be  
used in this form:

\definebodyfont
[30pt,25pt,20pt,18pt,17.3pt,14.4pt,14pt,12pt,11pt,11.5pt,10pt,9pt,8pt, 
7pt,6pt,5pt,4pt]
[rm]
[default]

If I specify a bodyfont with a size that's not in this list
\setupbodyfont[somebodyfont,19.7pt]
I get no errors, but no output either :-( If I add 19.7pt to the  
list, everything works again. Is there an explanation for this behavior?

It also looks like I should define a math font for these Greek fonts.  
It looks like ConTeXt will try to get certain symbols from math if  
they're not defined in the bodyfont. Is there a syntax for creating a  
default math font for an entire set of typescripts? I tried this

\starttypescript
\definetypeface [all] [mm] [math]  [times]        [default]  
[encoding=default]
\starttypescript

but it doesn't seem to work, if a symbol like \textdoublebracketleft  
is used, compilation will fail with this error:

! Math formula deleted: Insufficient symbol fonts.
\mathematics #1->\relax \ifmmode #1\else $#1$
                                              \fi
\doutfunihashglyph ...#1\endcsname {#2}\endcsname
                                                   \else  
\strippedcsname \uni...

Any suggestions would be welcome; apart from these problems, I'm  
basically done with the work.

All best

Thomas

This

   \definebodyfont [default] [rm] [tf=, ] % ...

should work, afaik

Before that call, you may need to do

   \definebodyfontenvironment [19.7pt]

as well (not sure)

Replacing [all] with [tsgreek] (or whatever you typescript is named)
should work.

Hope this helps,

Taco

Not here, I get errors:

Sigh... It works, but it destroys the scaling mechanism built into  
the module...

That was my question: the typescriptfile contains about 25 typefaces.  
Is there a way to specify one math font for all of them, or do I have  
to go the laborious way of adding such a line to every single one of  
them?

Thanks!

Thomas

Assuming you have them inside \starttypescript-s, you could replace

   [all] with [\typecriptone]

globally.

I'll be happy to test what you have now, if needed.

Cheers, Taco

Perhaps my sloppy typing lately is a side-effect of all those
spelling reform discussions in the netherlands lately. :-/

Make that: [\typescriptone]

Sorry,

Taco

tf= (nothing) is a bad idea

Oh (is that what the error came from?) I just wanted to stress the
use of [default] instead of explicit sizes. Sorry, miscommunication
on my part.

Cheers,
Taco
