Add an imperfect option to search a source file for email addresses.
New option: --file-emails or --fe
email addresses in files are freeform text and are nearly
impossible to parse. Still, might as well try to do a
somewhat acceptable job of finding them.
This code should find all addresses that are in the form
addr@domain.tld
The code assumes that up to 3 alphabetic words along
with dashes, commas, and periods that preceed the
email address are a name.
If 3 words are found for the name, and one of the first
two words are a single letter and period, or just a
single letter then the 3 words are use as name otherwise
the last 2 words are used.
Some variants that are shown correctly:
John Smith <jksmith@domain.org>
Random J. Developer <rjd@tld.com>
Random J. Developer (rjd@tld.com)
J. Random Developer rjd@tld.com
Variants that are shown nominally correctly:
Written by First Last (funny-addr@somecompany.com)
is shown as:
First Last <funny-addr@somecompany.com>
Variants that are shown incorrectly:
Some Really Long Name <srln@foo.bar>
MontaVista Software, Inc. <source@mvista.com>
are returned as:
Long Name <srln@foo.bar>
"Software, Inc" <source@mvista.com>
--roles and --rolestats show "(in file)" for matches.
For instance:
Without -file-emails:
$ ./scripts/get_maintainer.pl -f -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])
linux-kernel@vger.kernel.org (open list)
With -fe:
$ ./scripts/get_maintainer.pl -f -fe -nogit -roles net/core/netpoll.c
David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL])
Matt Mackall <mpm@selenic.com> (in file)
Ingo Molnar <mingo@redhat.com> (in file)
linux-kernel@vger.kernel.org (open list)
netdev@vger.kernel.org (open list:NETWORKING [GENERAL])
The number of email addresses in the file in not limited.
Neither is the number of returned email addresses.
