Does anyone know if there is a way to pass variables to a arbitrarily
run script? I tried this with no luck.
ruby script.rb VARIABLE=value
Option 1: parse ARGV directly. I think this is what rake does.
For example, to build a hash:
vars={}
ARGV.each do |str|
vars[$1]=$2 if str =~ /\A(.*?)=(.*)\z/
end
puts vars['VARIABLE']
Or you could use eval to set local variables if that's what you really
want (but I would strongly recommend against this)
Option 2: pass variables in the environment.
env VARIABLE=value ruby script.rb
#!/usr/bin/ruby
puts "You passed ", ENV['VARIABLE']
HTH,
