Converts AdBlock Plus filter lists to hosts file entries

hostsblock finds any domain-only blocking rules in an AdBlock Plus filter list (e.g. of the form (||some.domain.com^) and prints them as host file entries for 127.0.0.1 (e.g. 127.0.0.1 some.domain.com).

Standalone ad-blocking hosts files like http://someonewhocares.org/hosts/hosts are good, but since ABP filter lists are far more common and frequently updated, it's nice to have a tool to parse them.

make

hostsblock [LIST]

If the list argument is -, hostsblock will read from stdin.
