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. valid validates and normalizes semver strings and returns null for invalid formats
  2. clean strips leading and trailing characters leaving only the version number
  3. satisfies checks whether a semver string satisfies a range expression
  4. compare orders semantic versions in ascending precedence order
  5. rcompare orders semantic versions in descending precedence order
  6. rsort sorts an array of version strings in descending order in place
  7. diff determines the difference between two semantic versions
  8. inc increments semver versions by major minor or patch release types
  9. coerce extracts and formats a valid semver version from arbitrary strings
  10. minVersion returns the minimum semver version that can satisfy a range
