Seach for Tcl Expect equivalent

Hello,

Expect is a librarie/tools in perl or Tcl that is aim to control a process. You could send command on the stdin and wait for answer on stdout, then react on this event (thant why it is call 'expect').

Uselfull for executable tests, or control an automatic telnet session ...

I know OSProcess to launch executable and play with stdin/stdout but it's not exactly what do Expect.


Do you know something like that on Pharo ?

There are examples in CommandShellTestCase in category "testing-scripts".
Basically it works like this:

        result := CommandShell new
                script: 'who
                                help
                                ls -l NOSUCHFILE
                                help'
                onFailureDo: [:p | 'the pipeline collection that failed was ', p printString].

or this:

        CommandShell new
                if: 'who
                        ls NOSUCHFILE
                        pwd'
                then: ['the script succeeded']
                else: ['the script failed']

I do not know of anything equivalent to Expect, but if you are using

You're right. Expect is something like that but with more possibilities on what an application could put on stdout.

Thanks for the idea.
