Command line list display¶
A system administrator can display all the mailing lists via the command line. When there are no mailing lists, a helpful message is displayed.
>>> from mailman.testing.documentation import cli
>>> command = cli('mailman.commands.cli_lists.lists')
>>> command('mailman lists')
No matching mailing lists found
When there are a few mailing lists, they are shown in alphabetical order by their fully qualified list names, with a description.
>>> from mailman.interfaces.domain import IDomainManager
>>> from zope.component import getUtility
>>> getUtility(IDomainManager).add('example.net')
<Domain example.net...>
>>> from mailman.app.lifecycle import create_list
>>> mlist_1 = create_list('list-one@example.com')
>>> mlist_1.description = 'List One'
>>> mlist_2 = create_list('list-two@example.com')
>>> mlist_2.description = 'List Two'
>>> mlist_3 = create_list('list-one@example.net')
>>> mlist_3.description = 'List One in Example.Net'
>>> command('mailman lists')
3 matching mailing lists found:
list-one@example.com
list-one@example.net
list-two@example.com
Names¶
You can display the mailing list names with their posting addresses, using the
--names/-n
switch.
>>> command('mailman lists --names')
3 matching mailing lists found:
list-one@example.com [List-one]
list-one@example.net [List-one]
list-two@example.com [List-two]
Descriptions¶
You can also display the mailing list descriptions, using the
--descriptions/-d
option.
>>> command('mailman lists --descriptions --names')
3 matching mailing lists found:
list-one@example.com [List-one] - List One
list-one@example.net [List-one] - List One in Example.Net
list-two@example.com [List-two] - List Two
Maybe you want the descriptions but not the names.
>>> command('mailman lists --descriptions --no-names')
3 matching mailing lists found:
list-one@example.com - List One
list-one@example.net - List One in Example.Net
list-two@example.com - List Two
Less verbosity¶
There’s also a --quiet/-q
switch which reduces the verbosity a bit.
>>> command('mailman lists --quiet')
list-one@example.com
list-one@example.net
list-two@example.com
Specific domain¶
You can narrow the search down to a specific domain with the –domain option. A helpful message is displayed if no matching domains are given.
>>> command('mailman lists --domain example.org')
No matching mailing lists found
But if a matching domain is given, only mailing lists in that domain are shown.
>>> command('mailman lists --domain example.net')
1 matching mailing lists found:
list-one@example.net
More than one --domain
argument can be given; then all mailing lists in
matching domains are shown.
>>> command('mailman lists --domain example.com --domain example.net')
3 matching mailing lists found:
list-one@example.com
list-one@example.net
list-two@example.com
Advertised lists¶
Mailing lists can be “advertised” meaning their existence is public knowledge. Non-advertised lists are considered private. Display through the command line can select on this attribute.
>>> mlist_1.advertised = False
>>> command('mailman lists --advertised')
2 matching mailing lists found:
list-one@example.net
list-two@example.com
