Пакунок: ruby-tty-which (0.4.2-1)

platform-independent implementation of Unix which command

This library provides a platform-independent analogue of Unix `which` command.

TTY::Which has a `which` method that searches set of directories for an executable file based on the `PATH` environment variable, which returns an absolute path if the executable program exists, and `nil` otherwise.

This is part of the TTY components framework to easily build terminal applications in Ruby.
