For parsing ISC Bind9 DNS (named.conf) configuration file in Python3, I have built using PyParsing for this. It is 99% code completed. MIT license. Designed for Bind9 version 9.0 to 9.17.2.

Three issues left.

Solid unit-testing coverage, moderate-system testing.

Probably the largest PyParsing to date.
