My startup file for pry, the awesome REPL tool for Ruby.
.pryrc's Introduction
.pryrc
My startup file for pry, the awesome REPL tool for Ruby.
Most of these are shortcuts for system command aliases I use,
and I wanted them to be available while running pry.
Most of these are ruby one-liners, but they may help ruby-nubies
get a handle on some of the basic language syntax.
