Greek font in Footnote problem

Greek font in Footnote problem

[Alan Bowen]

I am having trouble getting Greek in footnote environment. The Greek  
appears as it should in the text body, but in a footnote all I get is  
the input. In short, ConTeXt \footnote seems to ignore the \localgreek  
command. I attach a brief test file that should produce the problem as  
well as the input file defining the Greek font in the first place.

Any suggestions would be very much appreciated.

By the way, there is no message in the log file to the effect that the  
Greek font is unavailable at a given font size. And I am using ConTeXt   
ver: 2004.10.26  fmt: 2005.1.3.

enablegreek relies on catcode changes, so it cannot work inside
commands. It should be redefined to make use of e-TeX's
\scantoken feature so that it can re-parse its input.

Giuseppe,

I'll be too bust the next three weeks to look into this, but would love 
to correct my quick and dirty hack. Can you give me a hint where I can 
learn more about \scantoken and how I can implement it for my Greek 
stuff?

Thanks

Thomas

Ehehehe. The reason why I was so generic in my answer is
precisely the same :)

Something like

\def\localgreek#1{\scantokens{\Gf\enablegreek#1}}

could work.

Guiseppe and Thomas—

A quick run though with my test file indicates that
	\def\localgreek#1{\scantokens{\Gf\enablegreek#1}}
will work in the body text, but only if one enters the Greek code using 
double braces as follows:
		{\localgreek{Greek code}}
With single braces either the Greek turns on and stays on thereafter or 
the breathings get messed up with initial spaces.

Still no Greek in the footnotes, though.

more precisely:

\starttext

\def\rescan#1{\scantokens{#1}} [\rescan{oeps}]

\def\rescan#1{\scantokens{#1\ignorespaces}} [\rescan{oeps}]

\stoptext

and therefore:

    \def\localgreek#1{\rescan{\Gf\enablegreek#1}}

Re: Greek font in Footnote problem

[Thomas A.Schmitz]

First: thanks to Giuseppe and Hans for their suggestions! As soon as I  
have a bit more time, I will look into the \scantokens command and try  
and correct my Greek modules. However, I had a couple of minutes today,  
and it looks like the solution to Alan's problem is much simpler. In  
your sample, Alan, if you replace

\setupbodyfont[cmr, 10.5pt]

with

\setupbodyfont[cmr, 10pt] %or 11 pt or 12 pt

the file compiles cleanly, with Greek in the footnotes where it should  
appear. So, for the time being, it doesn't seem to be a problem with  
the catcode changes. If I'm not mistaken, this would have given weird  
characters, but the problem was that the font change was not done at  
all.

So: I had already mailed off-list to Alan that I thought the problem  
was with defining the new bodyfont. And I think this is right. In my  
definition for  the Greek fonts, I have this line:

\definebodyfont[4pt,5pt,6pt,7pt,8pt,9pt,10pt,10.5pt,11pt,12pt,14pt,14.4p 
t,16pt,18pt,20pt,22pt][rm][Gf=greeoxon sa 1.08]

So I would assume the following:

1. When the body font of the document is 10, 11 or 12 pt, the footnote  
body font is in one of the predefined sizes, i.e. 8, 9, 10, whatever.
2. When the body font is a weird number like 10.5, ConTeXt (or is it  
eTeX itself?) recalculates the size for  the footnote, which will be an  
even weirder number. Accordingly, the definitions in my file won't work  
anymore.

Thusly: I looked at the source to find out by which factor the font in  
the footnotes is scaled, but couldn't find out. So my questions: how is  
this font size calculated? Or is it possible to give a "blanket"  
declaration for font sizes in my file (there is something like <-> in  
LaTeX which means "all sizes," if memory serves right).

Thanks for the help!

Best

Thomas
