Changelog

4.0.2 (2021-01-23)

Fixed

• A bug in zero parsing within SemVer prereleases. #42

4.0.1 (2020-10-22)

Fixed

• An infinite loop in Version comparison. aura#652

4.0.0 (2020-10-20)

Changed

• Breaking: VChunk now cannot be empty.
• Breaking: A Version now guarantees NonEmpty chunks.
• Breaking: A Mess now guarantees NonEmpty chunks, and its structure has been significantly changed. Particularly, Mess values are now aware of the Int values they hold (when they do), as well as "revision" values of the pattern rXYZ.
• Comparison of Version values is more memory efficient.

Added

• Version now has an extra field, _vMeta :: [VChunk] for capturing "metadata" like Semver. This prevents otherwise nice-looking versions from being demoted to Mess.
• The MChunk type to accomodate the changes to Mess mentioned above.

Removed

• Breaking: Version no longer has a Monoid instance.

Fixed

• "" no longer parses in any way. #32
• Version strings with trailing whitespace no longer parse via versioning. #33
• Particular edge cases involving Mess comparisons. aura#646
• A particular edge case involving prereleases in Version comparisons. aura#586

3.5.4 (2020-05-12)

Added

• The functions isIdeal, isGeneral, and isComplex for Bool-based inspection of parse results.
• messMajor, messMinor, messPatch, and messPatchChunk for improved introspection into Mess values.

Changed

• Improved Mess comparison logic.

3.5.3

• GHC 8.10 support.

3.5.2

• Added a new PVP type and parsers.

3.5.1.1

• GHC 8.8 compatibility.

3.5.0

• Updated to megaparsec-7. Our ParsingError type alias has changed to match Megaparsec's new error model, and errorBundlePretty is now exposed instead of the old parseErrorPretty.

3.4.0.1

• Enhanced the whitespace handling in semver', version', and mess'.

3.4.0

• Removed ParseV and surrounding machinery. Use versioning now instead of the parseV function.

3.3.2

• GHC 8.4.1 compatibility.

3.3.0

• New Semantic typeclass that provides Traversals for SemVer-like data out of all the version types. Text was also given an instance, so its much easier to manipulate directly:

λ "1.2.3" & minor %~ (+ 1)
"1.3.3"

Some Lenses and Traversals had their names changed or were removed entirely to accomodate this new typeclass.

• SemVer and Version should never contain negative values, so their numeric components were changed from Int to Word.

3.2.0

• Updated for megaparsec-6 and GHC 8.2.

3.1.1

• Added instances for common typeclasses: Generic, NFData, and Hashable. This is to avoid having users define these instances themselves as orphans. If there are more instances you want added, please let me know. Data was left out on purpose.

3.1.0

• Added support for epoch numbers in the Version type. These are numbers like the 1: in 1:2.3.4. These are used in Arch Linux in rare cases where packages change their versioning scheme, but need a reliable integer prefix to establish ordering. The Version type has been given a new field, _vEpoch :: Maybe Int, and a corresponding lens, vEpoch.

3.0.2

• Expose internal parsers so that they could be used in other parser programs that parse version numbers in larger files.

3.0.0

• Updated for megaparsec-5 and ghc-8

2.0.0

• Switched to megaparsec to perform all parsing as Text
• Support for legacy String removed
• Added more Traversals and INLINE'd all Lenses/Traversals

1.1.0

• Added Lenses and Traversals (no lens dependency)
