How to get Fabric to automatically (instead of user-interactively) interact with shell commands? Combine with pexpect?
As Glenn, I would say use pexpect; in addition,
have a look at this wrapper I wrote to script the pexpect behaviour from fabric:
from ilogue.fexpect import expect, expecting, run prompts = []prompts += expect('What is your name?','John')prompts += expect('Where do you live?','New York')with expecting(prompts): run('command')See also my blogpost on fexpect or how to handle prompts in fabric with pexpect
It's not either/or. You just need to run the fab command through pexpect:
child = pexpect.spawn('fab <task>')child.expect('prompt:')child.send('reponse to prompt')... etcThe fab command is just like any other command, so it can be scripted through pexpect.
For Windows users, use winpexpect. Make sure to use this version I linked as this version fixes some bugs in previous versions.
import sys, winpexpectchild = winpexpect.winspawn('ftp', ['<ftp host>'])child.logfile = sys.stdoutchild.expect('User.*:')child.sendline('username')child.expect('Password:')child.direct_sendline('password')child .sendline('ls')print('Now enter the FTP interactive mode')child.interact()
