I''m working on a protocol state machine I intend to share with this
list for feedback, but before we get that far I could use a little help:
Firefly:~/Desktop$ cat em_echo.rb
#!/usr/local/bin/ruby -w
require ''rubygems''
require ''eventmachine''
module EchoServer
def receive_data data
send_data ">>>you sent: #{data}"
close_connection if data =~ /quit/i
end
end
EventMachine::run {
EventMachine::start_server "192.168.0.100", 8081, EchoServer
}
Firefly:~/Desktop$ ruby em_echo.rb
/usr/local/lib/ruby/gems/1.8/gems/eventmachine-0.5.3/lib/
eventmachine.rb:190: warning: `&'' interpreted as argument prefix
/usr/local/lib/ruby/gems/1.8/gems/eventmachine-0.5.3/lib/
eventmachine.rb:419:in `start_tcp_server'': no acceptor (RuntimeError)
from /usr/local/lib/ruby/gems/1.8/gems/eventmachine-0.5.3/
lib/eventmachine.rb:419:in `start_server''
from em_echo.rb:14

from /usr/local/lib/ruby/gems/1.8/gems/eventmachine-0.5.3/
lib/eventmachine.rb:178:in `run''
from em_echo.rb:13
Uh, it broke... :(

Try using an IP address that''s valid on your machine. We really should change that 192.168.0.100 that''s given in the sample code.

Thx for the patch James- I just applied it to the SVN source. This also points out one of EvMa''s shortcomings- error reporting coming from the C++ code is not too useful. The smoking gun is here: eventmachine.rb:419:in `start_tcp_server'': no acceptor (RuntimeError) but how were you to know? So we gotta improve the error reporting as we go along. Also, have a look at the cool stuff Jeff Rose is doing in regard to pure Ruby: experiments/machine in the SVN tree.
