Permits adding additional directories to Perl’s default search path at compile time. The directories are added at the front of the search path.
use lib list
;
adds the directories specified in
list
to @INC
.
For each directory $dir in
list
, lib
looks for an architecture-specific
subdirectory that has an auto subdirectory under
it—that is, it looks for $dir/$archname/auto. If
it finds that directory, then $dir/$archname is
also added to the front of @INC
,
preceding $dir.
Normally, you should only add directories to @INC
. However, you can also delete
directories. The statement:
no lib list
deletes the first instance of each named directory from @INC
. To delete all instances of all the
specified names from @INC
, specify
:ALL
as the first parameter of
list
.
As with adding directories, lib
checks for a directory called
$dir/$archname/auto and deletes the
$dir/$archname directory from @INC
. You can restore @INC
to its original value with:
@INC = @lib::ORIG_INC;
