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. semver.toComparators parses compound OR ranges into a 2D array of comparator string sets
  2. semver.toComparators desugars caret and tilde ranges into lower and upper bounded comparators
  3. semver.toComparators expands hyphen range syntax into explicit greater-than-equal and less-than-equal comparators
  4. semver.toComparators parses wildcard range expressions as an empty string comparator
  5. semver.toComparators supports options like includePrerelease and loose when expanding range expressions
  6. toComparators is directly importable from semver/ranges/to-comparators
