•Re: Adding script location to include path

Well, this is using core libs, and does what your snippet does:

use FindBin qw($Bin);
use lib $Bin;
[download]

Not sure how that's "over three lines".

Please stop promoting FindBin. Makeshifts last the longest.	[reply]

I was referring to FindBin itself, which uses the same libs as the snippet (File::Spec, and File::Basename), and brings in Cwd, Carp, and Config as well. It's not much more (and most likely already loaded by other things anyway) but uneeded in this particular case. :) Whichever's easier for you. Either way works fine (at least I think it does.. haven't extensively tested every scenario), and comes in handy.	[reply]

But your code also in turn pulls in those libs! Let's experiment: $ cat <<END >in-yours use File::Spec; use File::Basename; use lib &dirname(File::Spec->rel2abs($0)); print "$_\n" for sort keys %INC; END $ perl in-yours >out-yours $ cat <<END >in-mine use FindBin qw($Bin); use lib $Bin; print "$_\n" for sort keys %INC; END $ perl in-mine >out-mine $ comm out-yours out-mine Carp.pm Config.pm Cwd.pm Exporter.pm Exporter/Heavy.pm File/Basename.pm File/Spec.pm File/Spec/Unix.pm FindBin.pm XSLoader.pm attributes.pm base.pm lib.pm re.pm strict.pm vars.pm warnings.pm warnings/register.pm $ [download] So, the only differences are `FindBin` itself and `Exporter::Heavy`. Your attempt to avoid Cwd, Carp, and Config are not avoided in the slightest. So please, don't try to reinvent the wheel until you know what that wheel is doing. -- Randal L.
