RBT::MapThisInputToThatRegisteredProgram
[]¶ ↑
This method will return nil if no registered program has been found for the given input. Otherwise it will return the real name of the program at hand.
.h files work as input as well.
Usage examples:
x = RBT::MapThisInputToThatRegisteredProgram[:php] x = RBT::MapThisInputToThatRegisteredProgram[:gee] x = RBT::MapThisInputToThatRegisteredProgram[:foobar] x = RBT::MapThisInputToThatRegisteredProgram['stdio.h'] x = RBT::MapThisInputToThatRegisteredProgram[:soxi] # => "sox"
