2 bajillion times a day I want to print a hashref and see whats inside. But every time I want to do that I have to type:
use Data::Dumper::Concise; print Dumper $hashref;
First of all, thats too much typing. And second of all I keep forgetting to delete my print statements when I check in.
The name is shorter which means its slightly less typing so I am already winning. But thats not the best part. Lets see how to use it.
On the command line I do this:
perl -MDevel::Dwarn codeIWantToDebug.pl
And then in my code I do this:
print ::Dwarn $hashref;
There are 2 levels of good here:
- Less typing.
- When I run my code without ‘perl -M’ I get compile time errors in all
the places I forgot to remove
print ::Dwarn $hashref.
