Btw, one feature I'd like to see in shortlog is the ability to use
regexps for email address matching, ie something like

'torvalds@.*transmeta.com' => 'Linus Torvalds'
...
'alan@.*swansea.linux.org.uk' => 'Alan Cox'
...
'[email protected]' => 'Benjamin LaHaise',
'bcrl@.*' => '?? Benjamin LaHaise',
..

I don't know whether you can force perl to do something like this, but if
somebody were to try...

if you change your list to:

@email_name_map = (
['torvalds@.*transmeta.com' => 'Linus Torvalds'],
...
['alan@.*swansea.linux.org.uk' => 'Alan Cox'],
...
['[email protected]' => 'Benjamin LaHaise'],
['bcrl@.*' => '?? Benjamin LaHaise'],
...);

something along these (untested) lines should do the trick:

sub email2name
{
my($email) = @_;
for my $i (@mailmap) {
my($pattern, $name) = @$i;
return $name if ($email =~ m/$pattern/i);
}

return '??';
}

Regards, Olaf.

I'd like to keep the hash for all those addresses that aren't wildcards
and that aren't regexps -- we have fast, that is O(1) to O(log n),
access to the hash (depending on Perl's implementation) and we have
worse than O(n) for regexp, where n is the count of address strings or
regexps.

Would you agree to a version that has a set of fixed addresses and a
separate list of regexps, tries the hash first and then a list of
regexps? That sounds like a) easy addition, b) good performance to me
(before implementing it). If so, I could add some code for that feature.

My perl-incantation wizard friend (I consider myself mere journeyman)
uses usually convoluted 'map' constructs to do things like this.
It is amazing high-power way to make things -- and often helps you to
make "write only" script.

Wrapping converter regular expressions into map {} structure gives
something like:

@summary = map {
s/torvalds\@.*transmeta.com/Linus Torvalds/,
s/alan\@.*swansea.linux.org.uk/Alan Cox/,
... etc ...
1
} @summary;

See "man perlfunc" and look for " map ".

Perl is very regex-friendly. Sure it can do this :)

Do we really care about performance here?

I think maintain-ability is probably more important.

In any case, splitting the lists into "fixed" and "regex" doesn't seem
like a bad idea, provided that the change was fairly easy and
self-contained.

How about this (search for 'Alan Cox' to see the syntax):

one suggestion I would make would be to break out the regex into a
seperate file, that way you will no longer need to touch the script once
the core logic is correct.

got this working nicely to count users based upon patterns.

wildcard). The split could be done while slurping the file
(check for /\*\[\]\+/).
