This repository is a community-maintained domain classification dataset used by V2Ray/Project V for geosite routing. It contains over 1,500 plaintext list files organized by company, service, region, or functional category (e.g., ads, AI, education, porn). Each file uses a compact rule language supporting domain, full, keyword, regexp entries, attributes (@cn, @!cn, @ads), and include directives for hierarchical composition. A Go builder (main.go) compiles these lists into a protobuf binary (dlc.dat) with deduplication, redundant subdomain pruning, and optional custom profile assembly. A companion tool (cmd/datdump) reverses the binary back to plaintext for auditing. The repository is primarily a data pipeline: raw curated lists are transformed into a consumable routing artifact. While the Go tooling is essential, the core value lies in the curated data and its modular, attribute-based taxonomy. This hybrid nature (data with application tooling) is typical of domain-specific datasets that require compilation.
This repository generates rule sets (RULE-SET) for the Clash Premium proxy tool, specifically tailored for users in China. The core of the repo is a GitHub Actions workflow (run.yml) that daily fetches domain and IP lists from multiple upstream sources (e.g., v2ray-rules-dat, domain-list-custom, dnsmasq-china-list, geoip) and transforms them into Clash-compatible YAML payload files. The output rule sets categorize domains into direct, proxy, reject, private, Apple, Google, GFW, etc. The codebase itself is minimal (only CI configuration) and the actual data artifacts are stored in a separate 'release' branch. The repository acts as a data pipeline, not an application, with the workflow serving as the sole processing logic. The pipeline is straightforward but effective, relying on standard Unix tools (curl, grep, perl, sed) for data transformation.
