It wouldn't be difficult to do, but at the moment, it wouldn't provide anything useful because of <https://gitlab.com/mailman/mailman/issues/453>.

The issue is now fixed in the branch head at least. The script corresponding to https://www.msapiro.net/scripts/last_post.py would be almost identical except for changing real_name to display_name, last_post_time to last_post_at and fixing the print for Python 3. Also changing the string interpolation to format(), it becomes:

import time

def last_post(mlist): print('{}: Last post at {}'.format( mlist.display_name, time.ctime(mlist.last_post_at) ))

The only issue with the script is for a list which has had no posts since #453 was fixed, mlist.last_post_at is None and time.ctime(None) is the current date and time.

That too could easily be fixed like:

import time

def last_post(mlist): if mlist.last_post_at: print('{}: Last post at {}'.format( mlist.display_name, time.ctime(mlist.last_post_at) )) else: print('{}: No posts'.format(mlist.display_name))

The trickier part is the Mailman 3 mailman withlist command has no option to run for all lists, so you'd need to run it something like

#!/bin/sh for list in mailman lists -q; do mailman withlist -r last_post -l $list done

Thanks for the leg up on converting that from mailman2 to mailman3 much appreciated.

I found 1 issue. When I had a list that was imported, but had not done another post after being imported, the script would fail with the following error: print('{}: Last post at {}'.format( mlist.display_name, time.ctime(mlist.last_post_at) )) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: 'datetime.datetime' object cannot be interpreted as an integer

Made a final change to set the mlist.last_post_at to mlist.last_post_at.timestamp() and that cleared the problem.

The final form of last_post.py is:

import time

def last_post(mlist): if mlist.last_post_at: print('{}: Last post at {}'.format( mlist.display_name, time.ctime(mlist.last_post_at.timestamp()) )) else: print('{}: No posts'.format(mlist.display_name))

Don't know if this will help others, but the place I put the last_post.py file was in: /opt/mailman/venv/bin (same location as the mailman script executable).
