NAME

MySQL::GrantParser - parse SHOW GRANTS and return as hash reference

SYNOPSIS

use MySQL::GrantParser;

# connect with existing dbh
my $dbh = DBI->connect(...);
my $grant_parser = MySQL::GrantParser->new(
    dbh => $dbh;
);

# connect with user, password
my $grant_parser = MySQL::GrantParser->new(
    user     => 'root',
    password => 'toor',
    hostname => '127.0.0.1',
);

# and parse!
my $grants = $grant_parser->parse; # => HashRef

DESCRIPTION

MySQL::GrantParser is SHOW GRANTS parser for MySQL, inspired by Ruby's Gratan.

This module returns privileges for all users as following hash reference.

{
    'USER@HOST' => {
        'user' => USER,
        'host' => HOST,
        'objects' => {
            'DB_NAME.TABLE_NAME' => {
                privs => [ PRIV_TYPE, PRIV_TYPE, ... ],
                with  => 'GRANT OPTION',
            },
            ...
        },
        'options' => {
            'identified' => '...',
            'required'   => '...',
        },
    },
    {
        ...
    },
}

For example, this GRANT statement

GRANT SELECT, INSERT, UPDATE, DELETE ON orcl.* TO 'scott'@'%' IDENTIFIED BY 'tiger' WITH GRANT OPTION;

is represented as following.

{
    'scott@%' => {
        user => 'scott',
        host => '%',
        objects => {
            '*.*' => {
                privs => [
                    'USAGE'
                ],
                with => '',
            },
            '`orcl`.*' => {
                privs => [
                    'SELECT',
                    'INSERT',
                    'UPDATE',
                    'DELETE',
                ],
                with => 'GRANT OPTION',
            }
        },
        options => {
            identified => "PASSWORD XXX",
            required => '',
        },
    },
}
