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.intersects returns true for overlapping caret ranges (^1.0.0 and ^1.5.0)
  2. semver.intersects returns false for non-overlapping major ranges (^1.0.0 and ^2.0.0)
  3. semver.intersects returns true for overlapping comparison ranges (>=1.0.0 <2.0.0 and >=1.5.0 <3.0.0)
  4. semver.intersects returns false for disjoint ranges (<1.0.0 and >2.0.0)
  5. semver.intersects returns true for overlapping tilde and caret ranges (~1.2.0 and ^1.2.3)
  6. semver.intersects returns false for disjoint tilde ranges (~1.2.0 and ~1.3.0)
  7. semver.intersects supports includePrerelease option to match prerelease versions against ranges
  8. doRangesIntersect wrapper function accurately checks range overlap
