watchr – Agile development tool – Ruby gem

watchr - Agile development tool that monitors a directory tree, and triggers a user defined action whenever an observed file is modified. Its most typical use is continuous testing, and as such it is a more flexible alternative to autotest.

Installation:

1. Open Command prompt

2. CMD>gem install watchr

 

Sample Usage:

code.rb 

puts  Time.now.to_s

 

To Run:

in CMD_EXACTPATH>watchr code.rb

 

Note:

Change the code and save frequently. Whenever you are saving the file, WATCHR will execute and displays output in command prompt.
