Parsley 4.4.0-RC1

Added alias for unsafe() namely, impure; moved the UnexpectedItem functionality into the VanillaGen object, where it should more appropriately live. Documentation of milestone releases completed. From here on out, there will be no further binary incompatible changes, and no new features ahead of 4.4.0.

Full Changelog: v4.4.0-M8...v4.4.0-RC1

Parsley 4.4.0-M8

Added x: A to the update width on ErrorGen, allowing for finer control. Also exposed withWidth to position, allowing for concise custom definitions of the verified/preventative error patterns in required.

Full Changelog: v4.4.0-M7...v4.4.0-M8

Parsley 4.4.0-M7

Added the profile combinator, optimised character reading when results are unused, and added ErrorGen for customising the prevent, verify, and filters. Note that label introduced in M1 has been removed, so code may require a recompile.

Full Changelog: v4.4.0-M6...v4.4.0-M7

Parsley 4.4.0-M6

Added span combinator, which allows for the extraction of the input consumed by a parser, as well as an optimisation that tries to drop the generation of results in parsers whose results are not needed. Added first-class combinator support for the Preventative Error pattern in parsley.errors.patterns. The debug combinator now supports any number of registers to be specified, allowing for tracking values within the state in a user-friendly way.

This milestone release exposes the following new combinators:

• count and count1 for counting how many times a parser succeeds.
• count, range, and range_ combinators that parse a parser within a range of possible times.
• Allowed for the configuration of the meaning of whitespace in TillNextWhitespace.
• Added the empty(n) combinator to parsley.Parsley, allowing for fine caret control.
• Added the guard helper combinator, which fails if the given parser does not successfully return true.
