Re: [Fab-user] variable substitution

[Brandon Whaley]

In the first example, you're trying to use a format method that is not supported in python.  In your second example, you're using the format operator on the second string instead of the first in the put call.  Here's what you should do:

def myput():

    myvar = env.host_string

    put('/source/%s-*' % myvar, '/mydest/')

So, I’ve been trying to add some more intelligence to my Fabric functions and am running into difficulties.

 

Say, I wanted to include env.host string as a variable into a put() call.

 

def myput():

                myvar=env.host_string

                put(‘/source/$myvar-*’,’/mydest/’, mode=0644)

 

…which returns a ValueError.

 

if I try this, as I would with a runtime argument.

 

def myput():

                myvar=env.host_string

                put(‘/source/%s-*’,’/mydest/’ % myvar)

 

…which returns a Type Error.

 

Is there a simple way to overcome my lack of python knowledge here?
