withlist(8)withlist(8)NAMEwithlist - General framework for interacting with a mailing list
object.
SYNOPSISwithlist [options] listname [args ...]
There are two ways to use this script: interactively or programmati‐
cally. Using it interactively allows you to play with, examine and
modify a MailList object from Python's interactive interpreter. When
running interactively, a MailList object called `m' will be available
in the global namespace. It also loads the class MailList into the
global namespace.
Programmatically, you can write a function to operate on a MailList
object, and this script will take care of the housekeeping (see below
for examples). In that case, the general usage syntax is:
OPTIONS-l, --lock
Lock the list when opening. Normally the list is opened
unlocked (e.g. for read-only operations). You can always lock
the file after the fact by typing `m.Lock()'
Note that if you use this option, you should explicitly call
m.Save() before exiting, since the interpreter's clean up proce‐
dure will not automatically save changes to the MailList object
(but it will unlock the list).
-i, --interactive
Leaves you at an interactive prompt after all other processing
is complete. This is the default unless the -r option is given.
-r [module.]callable, --run [module.]callable
This can be used to run a script with the opened MailList
object. This works by attempting to import module (which must
already be accessible on your sys.path), and then calling
callable from the module. callable can be a class or function;
it is called with the MailList object as the first argument. If
additional args are given on the command line, they are passed
as subsequent positional args to the callable.
Note that module. is optional; if it is omitted then a module
with the name callable will be imported.
The global variable `r' will be set to the results of this call.
-a, --all
This option only works with the -r option. Use this if you want
to execute the script on all mailing lists. When you use -a you
should not include a listname argument on the command line. The
variable `r' will be a list of all the results.
-q, --quiet
Suppress all status messages.
-h, --help
Print a small help text and exit
EXAMPLES
Here's an example of how to use the -r option. Say you have a file in
the Mailman installation directory called `listaddr.py', with the fol‐
lowing two functions:
def listaddr(mlist):
print mlist.GetListEmail()
def requestaddr(mlist):
print mlist.GetRequestEmail()
Now, from the command line you can print the list's posting address by
running the following from the command line:
% bin/withlist -r listaddr mylist
Loading list: mylist (unlocked)
Importing listaddr ...
Running listaddr.listaddr() ...
mylist@myhost.com
And you can print the list's request address by running:
% bin/withlist -r listaddr.requestaddr mylist
Loading list: mylist (unlocked)
Importing listaddr ...
Running listaddr.requestaddr() ...
mylist-request@myhost.com
As another example, say you wanted to change the password for a partic‐
ular user on a particular list. You could put the following function
in a file called `changepw.py':
from Mailman.Errors import NotAMemberError
def changepw(mlist, addr, newpasswd):
try:
mlist.setMemberPassword(addr, newpasswd)
mlist.Save()
except NotAMemberError:
print 'No address matched:', addr
and run this from the command line:
% bin/withlist -l -r changepw mylist somebody@somewhere.org foobar
