This module loads a user-managed website blocklist from ~/.hermes/config.yaml and optional shared list files. It is intentionally lightweight so web/browser tools can enforce URL policy without pulling in the heavier CLI config stack. Policy is cached in memory with a short TTL so config changes take effect quickly without re-reading the file on every URL check. ) annotationsN)Path)AnyDictListOptionalTuple)urlparseget_hermes_homeF)enableddomains shared_filesg>@zOptional[Dict[str, Any]]_cached_policy Optional[str]_cached_policy_pathgfloat_cached_policy_timereturnrc$tdz S)Nz config.yamlr 9/home/ubuntu/.hermes/hermes-agent/tools/website_policy.py_get_default_config_pathr(s   } ,,rceZdZdZdS)WebsitePolicyErrorz/Raised when a website policy file is malformed.N)__name__ __module__ __qualname____doc__rrrrr,s9999rrhoststrcx|pddS)N.)striplowerrstrip)r!s r_normalize_hostr)0s2 JB     % % ' ' . .s 3 33rrulerct|tsdS|}|r|drdSd|vrt |}|jp|j}|ddd d}|dr |dd}|pdS) N#:///rr%zwww.) isinstancer"r&r' startswithr netlocpathsplitr()r*valueparseds r_normalize_ruler84s dC t JJLL   E E$$S))t ~~% , KKQ   " ( ( * * 1 1# 6 6E abb  =Drr4 List[str]c |d}nd#t$r td|gcYStt f$r(}td||gcYd}~Sd}~wwxYwg}|D]T}|}|r|dr.t|}|r| |U|S)uLoad rules from a shared blocklist file.
