I've been trying to figure out how to access the archives programmatically.
I'm sure this is easy once you know, but googling various things hasn't
worked. What I want to do is graph the number of messages about PEP 572 by
time. (or has someone already done that?)
I installed GNU Mailman, and downloaded the gzip'ed archives for a number
of months and unzipped them, and I suspect that there's some way to get
them all into a single database, but it hasn't jumped out at me. If I
count the "Message-ID" lines, the "Subject:" lines, and the "\nFrom " lines
in one of those text files, I get slightly different numbers for each.
Alternatively, they're maybe *already* in a database, and I just need API
access to do the querying? Can someone help me out?
Like Victor, I download mailing list archives. Between pulling them in and also
subscribing, ideally I get a complete history in my "python" mail folder.
Likewise for other lists.
The mailman archives are UNIX mbox files, compressed, with a bit of header
munging (to make address harvesting harder). You can concatenate them and
uncompress and reverse the munging like this:
cat *.gz | gunzip | fix-mail-dates --mbox | un-at-
where fix-mail-dates is here:
https://bitbucket.org/cameron_simpson/css/src/tip/bin/fix-mail-dates
and un-at- is here:
https://bitbucket.org/cameron_simpson/css/src/tip/bin/un-at-
and the output is a nice UNIX mbox file.
You can load that into most mail readers or parse it with Python's email
modules (in the stdlib). It should be easy enough to scan such a thing and
count header contents etc. Ignore the "From " line content, prefer the "From:"
header. (Separate messages on "From " of course, just don't grab email
addresses from it.)
