bind::config::parser
BIND::Config::Parser(3pm) User Contributed Perl Documentation BIND::Config::Parser(3pm)NAME
BIND::Config::Parser - Parse BIND Config file.
SYNOPSIS
use BIND::Config::Parser;
# Create the parser
my $parser = new BIND::Config::Parser;
my $indent = 0;
# Set up callback handlers
$parser->set_open_block_handler( sub {
print " " x $indent, join( " ", @_ ), " {
";
$indent++;
} );
$parser->set_close_block_handler( sub {
$indent--;
print " " x $indent, "};
";
} );
$parser->set_statement_handler( sub {
print " " x $indent, join( " ", @_ ), ";
";
} );
# Parse the file
$parser->parse_file( "named.conf" );
DESCRIPTION
BIND::Config::Parser provides a lightweight parser to the configuration file syntax of BIND v8 and v9 using a "Parse::RecDescent" grammar.
It is in a similar vein to "BIND::Conf_Parser". However, as it has no knowledge of the directives, it doesn't need to be kept updated as
new directives are added, it simply knows how to carve up a BIND configuration file into logical chunks.
CONSTRUCTOR
new( );
Create a new "BIND::Config::Parser" object.
METHODS
set_open_block_handler( CODE_REF );
Set the code to be called when a configuration block is opened. At least one argument will be passed; the name of that block, for
example "options" or "zone", etc. as well as any additional items up to but not including the opening curly brace.
set_close_block_handler( CODE_REF );
Set the code to be called when a configuration block is closed. No arguments are passed.
set_statement_handler( CODE_REF );
Set the code to be called on a single line configuration element. At least one argument will be passed; the name of that element, as
well as any additional items up to but not including the ending semi-colon.
parse_file( FILENAME );
Parse FILENAME, triggering the above defined handlers on the relevant sections.
TODO
Probably the odd one or two things. I'm fairly sure the grammar is correct.
