# AdServers for Little Snitch 4

A very ~~hacky~~basic script to convert [Peter Lowe's AdServers blocklist][1] to the JSON-based [Little Snitch 4][2] [.lsrules][3] format, suitable for use as a [Rule group subscription][4].

It is worth noting that [@pgl][5] provides a [littlesnitch-rule-group-subscriptions][6] format, but this script uses the more compact `denied-remote-hosts` array format introduced in Little Snitch 4.2

This script requires internet access at least once, to curl the host blocklist, and emits JSON on stdout.

Subscribe rules are [embeddable][7] using the `x-littlesnitch:` URL scheme.

I eat my own dog food, and if you think you might also enjoy the taste I offer it to you with with the usual caveats that this is a best-effort endeavor, and if it breaks your system you get to keep both halves.
