Using Repl

On your local dev instance, the "backend" container comes with Devel::REPL installed.

Thanks to PERL5LIB variable which is already configured, you can load any module of ProductOpener from within it.

Also it as the right

Launch Repl

Just run

docker-compose run --rm docker-compose re.pl

If you want to access external services (like mongodb), do not forget to start them.

Testing perl code

It can be a handy way to get your hand into perl by testing some code patterns, or seeing how they react.

For example one can test a regular expression:

$ my $text = "Hello World";
Hello World
$ $text =~ /Hello (\w+)/i
World

Reading a sto

Another use case is reading a sto file to see what it contains.

Eg. for a user:

$ use ProductOpener::Store qw/:all/;
$ my $user_id = "xxxx";
$ my $user_ref = retrieve("/mnt/podata/users/$user_id.sto");
