Drop
, (*1)
"The most effective debugging tool is still careful thought, coupled with judiciously placed print statements.", (*2)
— Brian Kernighan, "Unix for Beginners" (1979), (*3)
While debugging small issues, you sometimes just want to see the contents of a variable or two. Firing up a full debugger can be overkill for quick problems, and var_dump(…); exit(1);
is a little unwieldy and only accepts a single argument., (*4)
drop()
is a simple debugging tool that allows you to drop one of more variable's contents in simple format that is friendly and readable on both web and CLI output., (*5)
see()
is similar to drop()
but it does not halt execution., (*6)

This was based on the work of my friend Jon Henderson before it was given its own repo., (*7)
