lib::abs - lib that makes relative path absolute to caller.
lib
Simple use like use lib ...:
use lib ...
use lib::abs qw(./mylibs1 ../mylibs2); use lib::abs 'mylibs'; # if your path may not exists and it is ok, then: use lib::abs -soft => qw(./mylibs1 ../mylibs2);
Extended syntax (glob)
use lib::abs 'modules/*/lib';
There are also may be used helper function from lib::abs (see example/ex4):
use lib::abs; # ... my $path = lib::abs::path('../path/relative/to/me'); # returns absolute path
The main reason of this library is transformate relative paths to absolute at the BEGIN stage, and push transformed to @INC. Relative path basis is not the current working directory, but the location of file, where the statement is (caller file). When using common lib, relative paths stays relative to curernt working directory,
BEGIN
@INC
# For ex: # script: /opt/scripts/my.pl use lib::abs '../lib'; # We run `/opt/scripts/my.pl` having cwd /home/mons # The @INC will contain '/opt/lib'; # We run `./my.pl` having cwd /opt # The @INC will contain '/opt/lib'; # We run `../my.pl` having cwd /opt/lib # The @INC will contain '/opt/lib';
Also this module is useful when writing tests, when you want to load strictly the module from ../lib, respecting the test file.
# t/00-test.t use lib::abs '../lib';
Also this is useful, when you running under mod_perl, use something like Apache::StatINC, and your application may change working directory. So in case of chdir StatINC fails to reload module if the @INC contain relative paths.
mod_perl
Apache::StatINC
StatINC
Q: We already have FindBin and lib, why we need this module?
FindBin
A: There are several reasons:
`use lib::abs "..."'
`use FindBin; use lib "$FindBin::Bin/../lib";'
