Convert various filter formats (DNS, ABP, uBlock Origin, AdBlock) to hosts list with 0.0.0.0 IP

This tool converts domain filter lists from various formats to a unified hosts file format with 0.0.0.0 IP addresses. It supports:

• Standard hosts files
• AdBlock/uBlock style domain filters (||domain.com^)
• Simple domain lists
• Comment and non-domain lines are automatically filtered out

1. Add your filter sources to filter_list.lst
2. Run ./ad_filter2hosts.sh
3. The resulting hosts file will be saved as hosts_filtered.txt

A GitHub Actions workflow automatically updates the hosts file daily. The latest version is always available in this repository as hosts_filtered.txt.

• The workflow runs daily at midnight UTC
• It can also be triggered manually from the Actions tab
• Statistics about the hosts file are available in hosts_info.md

The tool comes pre-configured with these filter sources:

• Cybo1927 host list (blocks anti-adblock pop-ups)
• Energized Spark
• Common AdBlock filter lists
• Default AdAway sources

You can customize the sources by editing the filter_list.lst file.
