0.5.0 (2022-04-18)

Breaking

• getLengthRange will now throw a RangeError instead of returning undefined for empty arrays.

Added

• Added isLengthRangeMinZero function that is equivalent to getLengthRange(e).min === 0 but implemented more efficiently.
• Added onlyInside option for getLongest function.

0.4.1 (2022-04-17)

Improved

• canReorder can now prove more alternatives to be safe to reorder.
• canReorder will now create a cache if none is provided.

0.4.0 (2022-04-16)

Breaking

• Dropped support for NodeJS 10. The library will likely still work on this NodeJS version, but it won't be tested and NodeJS-10-specific bugs will be rejected.

Added

• Added containsCapturingGroup.

• Added canReorder.

0.3.0 (2021-09-04)

Breaking

• The FirstLookChar, FirstFullyConsumedChar, and FirstPartiallyConsumedChar interfaces are now immutable.

Added

• Added transparent caching for all functions taking flags.
• Added FirstConsumedChars and FirstLookChars namespaces. They contain methods for working with FirstLookChars and FirstConsumedChars.
• Added FollowOperations.continueOutside to improve analysis inside lookaround assertions.
• Added FollowEndReason type.
• followPaths now supports alternatives as the start element.
• The getFirst{Consumed,}Char* functions now supports alternatives as the after-this element.

Improved

• The getFirst{Consumed,}Char* functions can now look outside of lookarounds to return better results.
• Improved how the exact property of FirstConsumedChars is determined. getFirstConsumedChar will now return better results.
• Improved documentation.
• Lots of internal refactoring and improvements.

Fixed

• Fixed that getFirstConsumedChar sometimes returned partially consumed chars with trivially rejecting looks instead of a fully consumed char.

0.2.4 (2021-08-12)

Fixed

• Fixed getFirst{Consumed,}Char* functions taking exponential time for some word boundary assertions.

0.2.3 (2021-07-15)
