How many GNU Emacs committers?

How many GNU Emacs committers?

[Mathias Huber]

Dear Emacs developers,

for http://www.linux-magazin.de I am researching the history of long
standing free software projects. Can anyone tell me how many committers
GNU Emacs has today?

Thanks,
Mathias

According to https://savannah.gnu.org/projects/emacs, there are 165
"active members".

You can also browse the git repository here to precisely check:
http://git.savannah.gnu.org/cgit/emacs.git/log/?h=trunk

Which means that are 165 people who have write access to the repository.
Some contributors aren't in there for some reason (tho they're rather
rare nowadays), but many of those 165 haven't committed anything in the
last 5 years.

Have a look at http://www.ohloh.net/p/emacs which does nice analytics on
the VCS logs, especially at
http://www.ohloh.net/p/emacs/contributors/summary.  That says 203
contributors (not committers) in the last year, and 39 in the last
month.

Checking the list of all contributors of all times, it's about 500.  (29
pages of each 20 contributors, but there are some duplicates when people
changed their mail address, etc.)

According to http://savannah.gnu.org/projects/emacs/, there are
currently 165 project members that have push access to the bzr
repository.

Actually, the total number is probably much larger than 500.  Back when
emacs used CVS, only the actual committers were logged, though they
probably committed tons of changes others sent them per mail but
couldn't commit themselves.  And there are many emacs packages that have
their own repositories (Org, Gnus, ERC, etc.), and not all of them are
synched on a per-commit basis with emacs' repository, so parts of their
contributors are probably not included in the statistics, too.

The names of the actual authors of the changes are always stated in
the ChangeLog entries, and always have been.

So I think the ChangeLog files are a much more accurate source of this
kind of information that the VCS logs, including for this reason:

Yes, sure.  But those are not analyzed by ohloh.net.

Indeed, so here's a try:

  $ cat **/ChangeLog* | grep '^[0-9]' | cut -d" " -f1 --complement \
        | sed -e 's/(.*)//' |sed -e 's/<.*>//' | sed -e 's/^[ ]\+//' \
        | sed -e 's/[ ]\+$//' | sort | uniq | wc -l
  1736

There are some duplicates when people sometimes use, e.g., "Richard
Stallman" and sometimes "Richard M. Stallman", and people with the same
name count only once, but matching only for names seemed to be more
correct than email addresses where sometimes people have used a good
dozen over the years.

Dear List,

thanks to everybody who replied!

And thank you for so scrupulously trying to get the numbers right!

I was thinking of a similar script, but you beat me to it, Tassilo :-)

See etc/AUTHORS for the more sophisticated version of this.

You mean, lisp/authors.el, yes?  Because etc/AUTHORS is only updated
before a release, AFAIK.

Hm, that (or etc/AUTHORS) actually contains 1385 people.  But there are
some that don't occur in any ChangeLog file (e.g. William Sommerfeld is
in AUTHORS but in no ChangeLog), and for some its the other way round,
too...  Ah, ok, the ones that are not in AUTHORS are those that only
have (tiny change) entries in ChangeLogs.

Everybody is in AUTHORS. It is currently complete up to the 24.3 release.
If you want today's information, then yes, you need to use M-x authors
to regenerate it.

The example I've found was

2012-08-17  Jan Beich  <jbeich@tormail.org>  (tiny change)

        * configure.ac (PTY_OPEN): Try posix_openpt on gnu-linux,
        gnu-kfreebsd, freebsd, and netbsd.  (Bug#12040)

in the top-level ChangeLog.  He's not in etc/AUTHORS, though 2012-08-17
is much before the 24.3 release.  These changes have been committed on
that very date (by you).

Anyway, after regenerating with M-x authors, he's in.

Yes, he is, in the emacs-24 branch. Guess I did not bother to merge
AUTHORS to trunk, since it is a generated file.

Here is the rough recipe.

1. M-x find-name-dired for ChangeLog files
2. % g for ^2012-
3. t k
4. RET all the ChangeLog files
5. M-x multi-occur-in-matching-buffers  on all ChangeLog buffers for  ^2012-
6. In occur buffer, keep only committer name i.e., delete lines nos, email etc
7. delete-duplicate-lines
8. There is also a org-sort-entries and some table magic thrown in.

I had to make some little modification to replace.el, so that it dumps
filenames instead of the buffer names.  I can send in the name of the
authors in each of the above directories that is ChangeLog-ged, if
there is some interest.

Dear List,

many thanks again for the clarification!

Summing up, GNU Emacs currently has 165 committers registered with
Savannah, and more than 1400 over all of its history.

I think it should be 167, Chong Yidong is in "inactive members", and
we have a new member recently.
