TxtMachine

Like ActionMailer, but for (outgoing) SMS, featuring pluggable adapters for different SMS gateways. Currently only supports iTAGG but writing a new adapter for your new provider should be quick and easy.

Warning - it's a little rough round the edges.

Quick Example

TxtMachine.configure(
  :gateway => TxtMachine::Gateways::Itagg,
  :username => "username",
  :password => "password",
  :originator => "Captain Haddock"
)

# Send a single message
TxtMachine.send_message("Message body", :to => "07123456789")

# Send a single message, alternative syntax
TxtMachine.send_message(:to => "07123456789", :body => "Message body")

# Send message to multiple recipients
TxtMachine.send_message("Foobar", :to => [number1, number2, number3])

# Open a session if your adapter uses stateful connections
TxtMachine.start do |tm|
  tm.send_message("Foobar", :to => some_number)
  tm.send_message("Bazbar", :to => some_other_number)
  tm.send_message("Bleem", :to => bob)
end

Writing an adapter

Check out TxtMachine::Gateways::Skeleton, it's probably easiest to extend this. Most SMS gateways I've seen use HTTP so all you need to do is implement the send method in your adapter to send in-place.

Using with Rails

Perform any global configuration using config.after_initialize within Rails::Initializer.run:

Rails::Initializer.run do |config|

  # ...
  
  config.gem "jaz303-txt_machine", :lib => "txt_machine"
  
  # ...
  
  config.after_initialize do
    TxtMachine[:originator] = "Bob's Sprockets Co"
  end
  
end

And then any per-env config in the appropriate file, again using config.after_initialize.

# in production.rb...

config.after_initialize do
  TxtMachine[:gateway] = My::Funky::Gateway
  TxtMachine[:api_key] = 'g1bb3r1sh'
end

Please use an after_initialize block otherwise things will get screwy with gems being inexplicably loaded twice.

Test Integration

Like ActionMailer, TxtMachine has a test mode which pushes all delivered messages onto an array:

# Equivalent to:
# TxtMachine[:gateway] = TxtMachine::Gateways::Test
# TxtMachine.clear_deliveries!
TxtMachine.test_mode!

TxtMachine.send_message("my message", :to => [r1, r2])

assert_equal 1, TxtMachine.deliveries.length
=> true

TxtMachine will detect Rails' test environment and set itself up accordingly.
