Preinstalled Strawberry Perl on Ivy Windows VM


Our VMs have Strawberry Perl 5.24 available as part of the Windows VM, as of the last writing. Licensed as open source under the GPL, it is most often used to develop mission critical software, and has excellent integration with markup languages such as HTML, XML, amongst others. Since it is both Object Oriented as well as procedural, it could be used within a multitude of programming projects. It includes built in database integration via its DBI module. Other than DBI, it has thousands of modules, making it one of the most extensible languages. Due to its interpreted nature, Perl is similar to Python and would be easy to understand for those familiar with Python.

Running Perl code

Strawberry Perl has an interactive interpreter, available under Start> All Programs> Strawberry Perl. Perl commands could be executed by simply typing perl -e <perl_code_goes here>. E.g. to print a number: perl -e ‘print 10’ the -e flag is simply to denote that the code is not a file, but code itself. To run a Perl script, do the following: perl <script_name_goes_here>

Installing modules

Since Ivy VM’s do not allow outward connections to CPAN’s website, you would have to install perl modules using the procedure below:

  1. Check if CPAN is installed and configured on your VM by typing cpan into a terminal window: cpan
  • If it asks you if CPAN needs to be configured, type yes
  • Once it is configured, type cpan to enter the CPAN shell
  • In a browser from outside the Ivy VM, search for the proper name of the Perl module you wish to download
  • E.g. if you want to install the MySQL driver for Perl, type install DBD::MySQL This would start the installation of the module. Ivy is able to download modules from CPAN using this method.

* You could manually install a module from its compressed file, once you have transferred the file into Ivy. However, using the process above downloads the modules’s dependencies as well.

Verifying if a module is installed

Run the following command after installing your module :

perldoc -l DBD::mysql

(e.g. if you installed DBD::mysql) It should output a path to the installed module.
