Hi,
I'm trying to restore ~ to its original meaning (i.e., the '~' character)
within a particular environment (\begin{CodeBox}...\end{CodeBox}, which is
an 'alltt' environment, so there's no need for a separate unbreakable
space). It's rather easy to redefine ~'s everywhere (with something like
sub pre_pre_process { s/(^|[^\\])\~/$1;spiTILDE;/g; } # [1]
sub post_post_process { s/;spiTILDE;/\~/g; }
in .latex2html-init). However, this also breaks legitimate uses of ~
outside of the environment.
A further difficulty is that the environment is defined in LaTeX, not as a
do_env_CodeBox() function, so I can't just add the above command ([1]) to
the right function... FWIW, it would probably be too much work to
redefine the whole environment in Perl.
So, does anyone know of a way to do the above substitution ([1]) only
within the CodeBox environment, or, alternatively, have a callback of
sorts that would be executed for every CodeBox environment that doesn't
have to redefine all of its processing? A way of invoking the latex2html
default processing from the callback would do it as well.
Thanks in advance,
Igor
P.S. My LaTeX code for CodeBox does a \begingroup\catcode`~=11...\endgroup
within the environment definition, so that's no help. :-(
