Return the boolean from evaluating the given marker against the environment. environment is an optional argument to override all or part of the determined environment. The *context* parameter specifies what context the markers are being evaluated for, which influences what markers are considered valid. Acceptable values are "metadata" (for core metadata; default), "lock_file", and "requirement" (i.e. all other situations). The environment is determined from the current Python process. r|r)r r!rrjr@)r rupdate frozensetrr_repair_python_full_version)rr{rcurrent_environments r*evaluatezMarker.evaluate;s # /1D1F1F   k ! !  & & {{ikk '     " "+-  (  "  & &{ 3 3 3---2Eg2N2V/1#G, M67JKK   r))rIr0r>r)r>r0)r>r)rrr>rh)Nr)r{rrrr>rh) r$r%r&rrrrrrr(r)r*rrs////2----%%%%::::''''.2#-" " " " " " " r)renvcvtt|d}|dr|d|d<|S)z Work around platform.python_version() returning something that is not PEP 440 compliant for non-tagged Python builds. r8+local)r r0endswith)rr8s r*rr`sJsC(=$>??##C((C(;%B%B%B !"
