One other benefit that I neglected to put into the previous post - I was
able to maintain separate cwd's for each tree.
An example of use:
Each tree has its own context, independent of the context of python:
>>> local, local2 = fs.LocalTree(), fs.LocalTree()
>>> local.pwd
'/home/targoz'
>>> local2.pwd
'/home/targoz'
>>> os.getcwd()
'/home/targoz'
>>> local.chdir('..')
>>> local2.chdir('www')
>>> local.pwd
'/home'
>>> local2.pwd
'/home/targoz/www'
>>> os.getcwd()
'/home/targoz'
Remote trees have the same interface:
>>> remote_login_data = {'username': 'targoz', 'password': 'my_pass',
host': 'hostname.com'}
>>> remote = fs.SSHTree(access=remote_login_data)
>>> remote.pwd()
'/home/nportal'
Trees can interact, regardless of whether they are local or remote:
>>> local2.listdir('files')
['myfile', 'otherfile.txt']
>>> remote.listdir()
[]
>>> localfile = local2.open(('targoz/myfile') # Opens a file-like object
>>> remote.savefile(localfile, 'remote_name')
>>> remote.listdir()
['myfile']
