Useful tools

pmtools is a collection of applications for managing perl modules. The documentation can be found here. Two of the most useful modules are:

pmpath shows full path to a perl module  
pman show a module’s man page  

For example, to determine whether File::Spec is installed, you would use the command

pmpath File::Spec

Using your own perl modules

Step 1. If you do not already have a directory where you put your perl modules, you must create a directory. Here we assume the directory is named perl5 and we create it in your home directory.

mkdir $HOME/perl5

Step 2. add the following two lines to your bashrc file:

module load myperl

The first line creates an environment variable that has the path to where you will install your private modules. (We assume your directory is named perl5, but if it is not, just use your directory name instead). The second line loads a module that configures your perl environment. In particular it adds all the needed paths to the PERL5LIB environment variable, so that perl can find the perl modules that you have installed.

Step. 3.

It is quite trivial, to install perl modules from the repository. For example, suppose you want to install a package that calculates the phase of the moon: Astro::MoonPhase. You would install it with the following command:

 cpanm --local-lib $MYPERL_INSTALL_BASE Astro::MoonPhase

cpanm will install the module in the directory you specified in $MYPERL_INSTALL_BASE. You can confirm that it was installed and that perl can find it by using the pmpath app:

 pmpath Astro::MoonPhase

You can also read the documentation with pman

pman Astro::MoonPhase
