There's no need to check. Just always reset it to normal. The worst that
can happen is you add a couple of bytes unnecessarily.
If you want to completely prohibit players from using color, a simple
solution is to double every '&' you encounter in their input. CircleMUD
already does this for '$' -- see process_input().
There are two main situations that arise as a result of such doubling.
The easiest to deal with is when the user's input is (at least in part)
going to be used verbatim as output, as in most communication commands,
titles, etc. This is easy to deal with because we don't actually need to
do anything beyond the doubling. The output functions already call the
interpret_colors() function, which smashes the consecutive '&' into a
single ampersand for us. Thus:
> say &rDark &Rred&w.
You say, '&rDark &Rred&w.'
making it appear to the user that there's no special processing of '&'
going on.
The other case is not much more difficult to deal with. Sometimes, you
will want to process the user's input as typed, either because you're
expecting arguments with an ampersand in it, are writing the input to a
file or some other place where interpret_colors() won't be called on it
and the doubling will be unattractive, or want to let the user use color
in this particular situation. In that case, you should make a manual call
to interpret_colors() to smash the doubling.
For example, you may want to let immortals use color in say, and thus
would do something like:
else {
char buf[MAX_INPUT_LENGTH + 12];
+ if (GET_LEVEL(ch) >= LVL_IMMORT) {
+ /* Smash doubled '&', letting immortals use colors. */
+ argument = interpret_colors(argument, FALSE);
+ }
snprintf(buf, sizeof(buf), "$n says, '%s'", argument);
