Base Grammar
EC::Grammars::DIG
- Digs into dig with url
Parser Actions
EC::Grammars::DIG
will provide important information parsed like the IPs, the urls,
used mainly for seeded out digs for P2P networks. A simple usage would be:
use EC::Grammars::DIG;
my $proc = run 'dig', URL_YOU_WANT_TO_DIG_HERE, :out, :err;
with $proc.err { say "Error running dig"; die; }
my $output = $proc.out.slurp: :close;
my $dig = EC::Grammars::DIG.new.parse( $output, :actions( EC:Grammars::DIG::Actions.new ) );
say $dig<DATE>; ## you may here query which ever tokens or rules desired
## TO ITERATE USE, FOR INSTANCE:
for $dig<ANSWER> -> $answers {
say $answers<IP>; ## for instance
Actions Options
:lax
Pass back, don't drop, quantities with unknown dimensions.
Installation
With zef:
zef install EC::Grammars::DIG
You'll first need to download and build Rakudo Star or better (http://rakudo.org/downloads/star/ - don't forget the final make install
):
Ensure that perl6
and panda
are available on your path, e.g. :
% export PATH=~/src/rakudo-star-2015.07/install/bin:$PATH
You can then use panda
to test and install CSS::Grammar
:
% panda install EC::Grammars::DIG
To try parsing some content:
% perl6 -MCSS::EC::Grammars::DIG -e"say EC::Grammars::DIG.parse( run 'dig', 'YOUR_URL_TO_DIG')"
