Hi,
I am having problems typing ">>" when typesetting code within a
\definetyping environment.
I hope someone might be able to give me a hint. My code looks as
follows:
\definetyping
[Haskell]
[ option=commands,
before={\startframedtext[width=\makeupwidth,
frame=off,bottomframe=on,topframe=on,
background=screen,backgroundscreen=.90]},
after={\stopframedtext},
bodyfont=9pt,
margin=1.5em]
\startHaskell
main = foo >>= bar
\stopHaskell
Whenever ConTeXt comes across >> anywhere in the text, it just doesn't
typeset anything. So in the above case, I get the output:
main = foo = bar
Thanks for you help!
Thomas

Confirmed. >> are eaten in MkII but everything works fine with MkIV. My
guess is because of automatic ligatures for >>. My usual trick for
disabling such ligatures in MkII is
\usetypescript [modern] [texnansi]
\setupbodyfont [modern]
but that does not work in this case. There were some discussions in the
past about disabling ligatures in typewriter font, but I don't remember
the exact solution.

No, the culprit is “option=commands" which gobbles “>>”.

You are absolutely right, Wolfgang. When removing the "option=commands"
from the definition, the ">>" won't get eaten. (Thanks!) However, my
whole code consists of things such as
\startHaskell
main = f1 /BTEX$\circ$/ETEX f2 >>= hey
\stopHaskell
How comes that the ">>" are gobbled? Even worse, something like
\startHaskell
foo = bar =<< print
\stopHaskell
won't even compile. It doesn't like "<<".
Question: Is there a way to replace the ">>" and "<<" strings in
the typesetting environment by something else? Or another work around?
Thanks,
Thomas

maybe
\startHaskell
foo = bar =/BTEX<</ETEX print
foo = bar =/BTEX$<<$/ETEX print
\stopHaskell

For anyone who's interested, I
will do the following now:
\startHaskell
foo /BTEX{\tt >>\!=}/ETEX bar
foo /BTEX>>\!=/ETEX bar
bar /BTEX{\tt =\!<<}/ETEX foo
bar /BTEX=\!<</ETEX foo
\stopHaskell
looks pretty nice, although it isn't really what I intended
at the start.
Best,
Thomas

this is because << >> is considered grouping
just use mkiv
