urlblock is a C library for blocking URLs based on simple, predefined rules. The rules will be compiled into the library, allowing you to fully embed urlblock's functionality in your programs.

Before you can build urlblock, you need to create your own set of rules:

mkdir data
touch data/hosts.txt
touch data/paths.txt

These rules will be used to block URLs. The data/hosts.txt file should contain all blacklisted hostnames. The data/paths.txt file should contain blacklisted keywords, which will be matched anywhere inside the URL's path component.

The utils directory contains a Python script, which can be used to create these rule files based on AdBlock filter lists and UNIX hosts files.

python utils/import.py PATH...

Once you have defined your own set of rules, urlblock can be build by running

make
make test
