script to send changesets per mail

[Martin Waitz]

hoi :)

I just tested my little script that can send changesets per mail.
okok, it still had a bug when I first tested it but that should be
fixed now.

If anyone is interested (perhaps for Documentation/BK-usage), here it
is:


#!/usr/bin/perl -w

# after sending an announcement (created by Documentation/BK-usage/bk-make-sum)
# just pipe your mail through this script.
# It will create one new mail per Changeset, properly threaded.

my $from;
my $to;
my $cc;
my $references;

# all local repositories are in ~/src/.
# you have to adjust this function if you keep them elsewhere.
sub local_repository($) {
        my $repo;
        
        $repo= shift;

        $repo =~ s,.*/,"$ENV{HOME}/src/",e;
        return $repo;
}

# this checks if we are allowed to send mails with this sender
# please modify the regexp to check for your adress!
sub check_from($) {
        my $from = shift;

        exit 1 unless $from =~ /insert-your-email-here/; #FIXME
}

# send one changeset.
# Parameters: the cset number, description prefix and the actual description.

        my ($cset, $serial, $desc, $longdesc) = @_;

        open (MAIL, "| /usr/sbin/sendmail -t") or die "fork sendmail: $!";
