Would like mode for 'call' that exposes the return value, and exits

[deanrad]

We have cli scripts that we want to call a ddp method, obtain the return value, then exit.. Can this be done with the tool in its current state?

[deanrad]

Here's an expect script that gets it done. But I think my coworker @arnaudsj might be proposing an actual patch...

> ddp-exec.sh 8081 methodName arg1
spawn ddp --port 8081 call methodName arg1
[msg]: {"server_id":"0"}
[msg]: {"msg":"connected","session":"xR86i3vQcSNGyBEaf"}
[call]: methodName ["arg1"]
[msg]: {"msg":"updated","methods":["1"]}
[msg]: {"msg":"result","id":"1","result":{}}
> echo $?
0

> cat ddp_exec.sh
#!/usr/bin/expect --
set timeout 3
set port [lindex $argv 0]
set method [lindex $argv 1]
set arg [lindex $argv 2]
log_user 0 # uncomment to silence
spawn ddp --port $port call $method $arg
expect '"msg":"result"'
