colors and text, prettyprinting

colors and text, prettyprinting

[Patrick Gundlach]

Hi, 

is this a bug or a feature?

% output=pdf
\setupcolors[state=start]
\starttext
\yellow
yellow??
\stoptext

generates endless(?) pages. Using \bgroup...\egroup or { .. } is 
ok.

ConTeXt  ver: 2001.7.11  fmt: 2001.7.16  int: english  mes: english

This is pdfeTeX, Version 3.14159-14h-released-20010417-2.1 (Web2C 7.3.3.1)
entering extended mode
(./color.tex{/app/unido-inf/sun4_56/tetex/1.0.7/share/texmf/pdftex/config/pdfte
x.cfg}

Prettyprinting works the way I wanted to. Thanks! One more 
question:
How can I define something like %%\ N  in TeX prettyprinting:

\startTEX
\def\mathematics#1% %%\ N usage: \type {\mathematics{x^2}} 
\stopTEX

This doesn't work:

\startPON
inst auth+ myauth {  // comment
  target  = /home/users ; %%\ N  \type{...}
\stopPON

Viele Grüße,

  Patrick Gundlach

a buggy feature; i'm still breeding on a proper solution for this; it has 
to do with teh color reset node ending up on the next page, which means 
that it's non empty, which means another page ...

Since you don't groupe \yellow, the stopcolor ends up after a group; try 
\startcolor[...] \stopcolor instead, or try [which is what we do currently]

\appendtoks \startcolor[yellow]\to\everystarttext
\appendtoks \stopcolor         \to\everystoptext

Prettyprinting works the way I wanted to. Thanks! One more

ah, you want to become a wizzard:

\installnewpretty

[see verb-ini.tex for example]; beware of grouping !

this works. Even the (dirtier?) one:

\appendtoks \bgroup \to\everystarttext
\appendtoks \egroup \to\everystoptext

:-)

No, I just want to use the very nice features context has ;-)

I've got it working now. I was not aware of the fact (use the 
source, luke) that it worked only in 'comment' mode... I feel 
more enlightened now. Thank you.

A happy Patrick
