Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert semver.toComparators splits hyphen range expressions into inclusive lower and upper bound comparators
  2. assert semver.toComparators expands tilde ranges into lower bound and next minor upper bound comparators
  3. assert semver.toComparators expands caret ranges into lower bound and next major upper bound comparators
  4. assert semver.toComparators parses disjunctive OR ranges into multiple comparator sets
  5. assert semver.toComparators returns empty string comparator for wildcard star ranges
  6. assert semver.toComparators preserves comparator sets for compound ranges and supports options such as includePrerelease
