In Perl, libraries are referred to as modules. To import a module, we use the use keyword followed by the name of the module.
Here is an example of importing the Time::Piece module:
use Time::Piece;
We can also import specific functions or variables from a module using the import function:
use Time::Piece qw(strftime);
This imports the strftime function from the Time::Piece module.
It is also possible to import functions or variables from a module with a different name:
use Time::Piece qw(strftime asctime => $my_time);
This imports the strftime function from the Time::Piece module and the asctime variable as $my_time.
Additionally, we can use the require() function to load modules only on demand:
require Time::Piece;
This will only load the Time::Piece module when it's actually needed.
Note: It's important to use proper capitalization when importing modules, as Perl is case-sensitive.
Overall, importing modules in Perl is a straightforward process that allows us to leverage pre-built code to accomplish our tasks more efficiently.
