Parsley 2.4.4

This release guarantees full thread-safety of the AST and compilation step of Parsley. In addition, code generation times have improved, and potential code blow-up has been mitigated for parsers which heavily influence the default error messages. Consists of work performed in #58 and undoes work done in #57.

Parsley 2.4.3

This one should hopefully fix the same race condition that 2.4.2 apparently fixed. This one is really quite a tricky one...

Parsley 2.4.2

This release should fix an apparent race condition when two threads try and compile a shared parser (running a shared parser is completely thread-safe!) #57

Parsley 2.4.1

Fixed #54, which essentially rendered decide with two arguments useless. It now works as intended.

Parsley 2.4.0

As it turns out, the ~> and <~ combinators were missing from the API. This has been rectified. In addition, collectMsg has been added for finer control over error messages when using the collect combinator.

Parsley 2.3.0

This release merges the #42 and #43 PRs.

What's New

• Added reduceLeft, reduceLeftOption, reduceRight, reduceRightOption combinators
• Added the zip alias to <~>
• Improved performance of foldLeft and foldLeft1
• Slight performance improvement for chain.left1 and chain.left
• Added parseFromFile method to parsers

Parsley 2.2.2

This version addresses a very minor duplication in foldRight1 and foldLeft1, where they unnecessarily duplicate the callee, instead of generating a subroutine.

Parsley 2.2.1

Fixed a bug where chain.left1 does not correctly wrap up a lone atom when the operator fails (since it was left on the stack unchanged). This affected generalised precedence tables.

Parsley 2.2.0

This release has laid the groundwork (and hopefully final!) for the Parsley 3.0.0 new-style API. Any and all of the old-style API has been deprecated strongly and will be removed in Parsley 3.0.0. A full description of these changes can be found here.

What's New

In addition to lift1 through lift3, lift4 through lift22 have been added to parsley.lift. To complement these, parsley.implicits contains some extension methods which allow the method .lift on any value or function (corresponding to pure or the liftN of the correct arity N).

The logic of the former ExpressionParser has been redesigned and can be found in parsley.expr
