Hi,
I've found myself writing the same script again and again for a client.
Given a set of log files, if such and such field match such and such
condition, then process them in a certain way. I've put the logic
in a module, and I'm now looking for a name for it. I'd also like
to know if this module looks useful to others (it was to me, since it
allowed me to write a CGI that "grepped" through numerous log files
and returned a subset of them as an HTML or CSV file).
The module works like this:
use Blah; # not a very good name for CPAN :-)
my $blah = Blah->new(
delimiter => ':',
fields => [qw( bap clank glipp plop )],
show => \&show_my_data,
);
# quelques infos utiles
$blah->add_filter(
bap => 'eq "zlopp"',
clank => '!~ /clunk_eth/',
);
$blah->add_file( glob "*.log" );
$blah->run;
When the run() method is called, the object compute a piece of Perl
code which is then eval()ed (with a localised @ARGV). The computed
code is the following (note the use of arrays for the selection pass
and of a hash for the processing):
while(<>) {
chomp;
my @data = split qr{:};
if( ( $data[1] !~ /clunk_eth/ )
&& ( $data[0] eq "zlopp" ) )
{
my %data;
@data{qw(bap clank glipp plop)} = @data;
$self->{show}->(\%data);
}
}
In future versions, I may add support for regular expressions for
parsing the fields (thus allowing a nice connection with my other module
Regexp::Log), the possibility to keep using an array for processing,
and have a better interface to add conditions (this is very crude,
and open to attacks if people using this module are not very careful).
I haven't been very successful in finding a name for this module.
Sébastien Aperghis-Tramoni proposed Log::Process, but maybe a name
like Log::Processor would be better.
Any other name ideas or comments about the module and its interface?
