ABP’s filter list syntax is underspecified with vague, conversational English; some members of the community have tried to formally document the more common pie

ABP’s filter list syntax is underspecified with vague, conversational English; some members of the community have tried to formally document the more common pieces of syntax but it’s far from complete. Instead of using a simple-to-parse CFG or regular expressions, ABP appears to have arbitrarily added new bits of syntax as they please. I’d encourage you to attempt to make an ABP filter list decoder before calling ABP alternatives “easy”.
