I don't know why u think u have a @INC problem. There's lots of ways to do
it. use lib "path", push @INC, path, perl -Ipath. U can even put an
anonymous routine directly in @INC that will be evaluated to come up with
the approriate path.
Yes, I will have to calculate the path, since it is not absolute.
If I put a relative path in @INC, I guess it would be relative to the
current directory. Which is whatever the directory the console is in
when it runs the script. Not very useful for finding modules. Instead
I want to find a path relative to where the script is located.
(Actually, I'm interested in finding the parent directory of the one
where the script is located.) As far as I can tell, there is no
function that tells me that. That is why I have to calculate it.
I suppose putting the path determination stuff in a function, and
putting a pointer to that in @INC would work. I guess I just felt
skiddish about it because it seems unusual.
What is the most common way that people handle this? That is, say your
modules are in the same folder as the main script. (Which I would think
would be the most common case, except for CPAN or PPM modules.) Do
people usually write a function to determine where the script is
located? You'd think there would be a common function for this....
My code currently handles it is below, which seems incredibly obtuse,
but I couldn't figure a simpler reliable way. That is the code I'd have
to pass in as a function to @INC (except with 'return' instead of 'chdir').
#---- determine V-ASC installation directory -------------------------------
#-- it is the parent directory of where this file is run from
my ($VAscVolume,$ServerPath) =
File::Spec->splitpath(File::Spec->rel2abs($0));
my @ServerDirs = File::Spec->splitdir($ServerPath);
my $VAscPath = File::Spec->catdir(@[EMAIL PROTECTED]);
my $VAscInstallDir
= File::Spec->canonpath(File::Spec->catpath($VAscVolume,$VAscPath,''));
my $VAscServerDir
=
File::Spec->canonpath(File::Spec->catpath($VAscVolume,$ServerPath,''));
chdir $VAscInstallDir;
