Patterns in lazy_regex_patterns.PATTERNS are known to be valid, so they will be compiled lazily. Other patterns will be compiled immediately, as it is not known if they will compile or raise an re.error. For more information on the arguments, see: https://docs.python.org/3/howto/regex.html#compilation-flags Args: pattern: The pattern to be compiled. flags: Flags to be used during compilation. Returns: An SRE_Pattern or a _Lazy_SRE_Pattern. Raises: re.error: If the arguments do not form a valid regex pattern. )rPATTERNSrr)r r s r _lazy_compiler&6s-$ #,,, We ,, gu %%rc"tt_yr)r&recompiler#rrinitialize_lazy_compiler*Ms "*rr)r" __future__rrrr(googlecloudsdk.core.utilrr)rr rr&r*r#rrr-s;"O&' 8zz ++,&.r
