BIND::Config::Parser provides a lightweight parser to the configuration file syntax of \s-1BIND\s0 v8 and v9 using a \*(C`Parse::RecDescent\*(C' grammar.

It is in a similar vein to \*(C`BIND::Conf_Parser\*(C'. 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 \s-1BIND\s0 configuration file into logical chunks.

new( );

Create a new \*(C`BIND::Config::Parser\*(C' object.

set_open_block_handler( \s-1CODE_REF\s0 );

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 \*(C`options\*(C' or \*(C`zone\*(C', etc. as well as any additional items up to but not including the opening curly brace.

set_close_block_handler( \s-1CODE_REF\s0 );

Set the code to be called when a configuration block is closed. No arguments are passed.

set_statement_handler( \s-1CODE_REF\s0 );

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( \s-1FILENAME\s0 );

Parse \s-1FILENAME\s0, triggering the above defined handlers on the relevant sections.

Probably the odd one or two things. I'm fairly sure the grammar is correct.
