Perl is an interpreted programming language. Perl is used to convert various text files into usable source code and for various source code checks. Perl version 5.6 and above should work fine.

Unix

Perl is available for most UNIX and UNIX-like platforms. If it isn’t already installed or available as a package for your platform, you can get it at https://www.perl.org/.

After correct installation, typing at the bash command line prompt:

$ perl --version

should result in something like:

This is perl 5, version 26, subversion 0 (v5.26.0) built for x86_64-linux-gnu-thread-multi
(with 62 registered patches, see perl -V for more detail)

this system using "man perl" or "perldoc perl".  If you have access to the
Internet, point your browser at http://www.perl.org/, the Perl Home Page.

However, the version string may vary.

Windows

A native Windows Perl package can be obtained from Strawberry Perl or Active State. The installation should be straightforward.

You may also use Chocolatey to install either package:

PS:\> choco install strawberryperl

or

PS:\> choco install activeperl

After correct installation, typing at the command line prompt (cmd.exe):

> perl -v

should result in something like:

This is perl, v5.8.0 built for MSWin32-x86-multi-thread
(with 1 registered patch, see perl -V for more detail)
