Writing modules in Ruby is as easy as writing a module in Python or bash. You just need to take care of the arguments, errors, return statements, and of course, know basic Ruby! Let's create the library/rsync.rb file with the following code:
#!/usr/bin/env ruby
require 'rsync'
require 'json'
src = ''
dest = ''
ret_msg = ''
SUCCESS = ''
def print_message(state, mdg, key='Failed')
message = {
key => state,
"msg" => msg
}
print message.to_json
exit 1 if state == false
exit 0
end
args_file = ARGV[0]
data = File.read(args_file)
arguments = data.split(" ")
arguments.each do |argument|
print_message(false, "Argument should be name-value pairs. Example name=foo") if not argument.include("=")
field.value = argument.split("=")
if field == "src"
src = value
elseif field == "dest"
