  • Default maxLookahead changed to 4 (opens new window)
    • Originally the default maxLookahead was 5, This could cause very slow parser initialization under certain edge case during ambiguity detection, however the vast majority of grammars do not require five tokens of lookahead. A smaller default avoids these potential slow downs while still allows overriding in unique cases which require a large lookahead.

  • More Functional Parsing DSL API. (opens new window)
    • This change broke a couple of APIS:
      • "OPTION" now returns the value of the inner grammar implementation or undefined otherwise instead of a boolean.
      • The "*_SEP" methods now return an object made up of two arrays, separators and values instead of a single array of separators.

# Minor Changes

# Major Changes

This release is is focused on performance improvements, with ~20% boost on V8 and potentially ~100% (double) performance on SpiderMonkey (FireFox 49).

To enjoy the maximum performance boost the new SimpleLazyTokens should be used. See:Token Types Docs for additional details.

# Breaking Changes

Certain advanced uses cases of dynamically defined Tokens (opens new window) Will break if some of new lookahead optimizations are enabled.

To resolve this a new property dynamicTokensEnabled has been defined on the IParserConfig (opens new window) interface. This configuration property is disabled by default, but can be enabled to support the use case of dynamically defined tokens. See the dynamically defined Tokens (opens new window) example for details.

# Major Changes

This Release includes a new performance feature called "Lazy Tokens". These tokens contain less actual state and defer the calculation of their properties until needed. Considering most of the time this information is never needed (full position information) the overall speed boost can be as much as 10-25% (depending on the grammar used).

See "2. Use Lazy Tokens" (opens new window) for more details.

# 0.13.0 (8-6-2016)

# Major Changes

This release includes major performance optimizations and guidelines. Anywhere from 20% to 100% was measured (on V8) depending on the grammar used. Please read the Performance FAQ section, as much of the performance gain is achieved by changing the way a Chevrotain parser is initialized which will require code changes (not mandatory) in user's code.
