I know you can do this with closures, but I'm wondering
if there is a better way. Here is the example:
a();
b();
print "$var\n";
sub a {
local $var = "a\n";
c();
}
sub b {
local $var = "b\n";
c();
}
sub c {
# i'm pleasing you to print a or b
print "var: $var";
}
So you can see, I want c() to have access to the calling
sub's my variables. I know that if I eval the creation
of that sub in a() or b() it will work, however I don't
want to have to do that for every sub that calls c().
Is there a hack to do the above?
If not, here is my next best choice... the sub c()
is actually spit out by a class and evaled in the
callers package, is it possible to have the eval
happen in the callers namespace?
That is:
$b = new SubMaker();
sub a {
my $var;
$b->make_sub("subname");
subname();
}
where SubMaker::make_sub() evals in the callers namespace
so that subname() now has access to $var.
Is that possible?
thanks.
