Changelog and Acknowledgements

2.2.1

• Fixed #26 where wide UTF-8 characters were not handled correctly.
• Docs fully updated for UTF-8 instead of UTF-16. (Docs were deleted from the 2.2.0 release.)

2.2.0

• Switched to UTF-8 to support text 2.0, implementing #22. text < 2 is no longer supported.
  • Changed type synonym PCRE2_UCHAR from CUShort to CUChar in the low-level bindings.
  • No API changes in the high-level bindings.
  • There is a minor regression in the ability to match \R against line separators (U+2028) and paragraph separators (U+2029). See #26.

2.1.1.1

• Updated library, tests, and docs for mtl 2.3 and microlens-platform 0.4.3.0. The mtl part of this is pursuant to #30.

2.1.1

• Added pattern serialization API, which fixes #23.
• Updated PCRE2 to 10.40 (no API changes).

2.1.0.1

• Explicitly required text < 2.
• Minor docs adjustments.

2.1.0

• Replaced Proxy :: Proxy info with type applications in splices from regex/_regex. This significantly shortens the splices, producing nicer error messages. As a very minor consequence, we now require the user to turn on {-# LANGUAGE TypeApplications #-} when using regex/_regex with patterns with parenthesized captures, even when not using capture/_capture.

2.0.5

• Enabled PCRE2's built-in Unicode support, which fixes #21.

2.0.4

• Added Show instance for Captures to ease debugging user code.

2.0.3

• Updated PCRE2 to 10.39 (no API changes). The C sources are now drawn from https://github.com/PhilipHazel/pcre2, which fixes #10.

2.0.2

• Fixed a minor issue where the caret indicating pattern location of a Pcre2CompileException was misplaced if the pattern contained a newline.

2.0.1

• Added microlens as a dependency to improve Haddock docs (Traversal' et al. are clickable) and relieve maintenance burden somewhat.
• Moderate refactoring of internals.

2.0.0

This release introduces significant breaking changes in order to make the API smaller, more consistent, and safer.

• Implemented #18:
  • Removed matchAll, matchAllOpt, capturesAll, and capturesAllOpt.
  • Upgraded match, matchOpt, captures, and capturesOpt to offer their functionality, respectively.
  • Renamed capturesA and capturesAOpt to captures and capturesOpt, replacing the latter two functions altogether. captures/-Opt were intended to be extreme convenience functions that required no special datatypes beyond the Prelude. However, this was of doubtful benefit, since that's false anyway—they required Text, not to mention {-# LANGUAGE OverloadedStrings #-}. Their names are simple and valuable, and no other Alternative-producing function has the naming convention "-A", so repurposing their names was in order.
• Moved the callout interface to a new module, Text.Regex.Pcre2.Unsafe. This includes the options UnsafeCompileRecGuard, UnsafeCallout, UnsafeSubCallout, and AutoCallout, and the types CalloutInfo, CalloutIndex, CalloutResult, SubCalloutInfo, and SubCalloutResult.
• Also moved option BadEscapeIsLiteral there.
• Removed the ineffectual options DupNames and Utf.

Other improvements with no API impact:

• Updated PCRE2 to 10.37.
• Replaced copied C files with symlinks, diminishing codebase by 1.5K lines and simplifying future PCRE2 updates.
• Reduced size of Template Haskell splices to make error messages less obnoxious.
• Moderate refactoring of internals and documentation.

1.1.5

• Fixed #17, where functions returning Alternative containers were not restricted to single results despite their documentation.
• Minor improvements to docs and examples.

1.1.4

• Fixed some incorrect foreign imports' safety.

1.1.3.1

• Fixed a very minor issue where pcreVersion still reported "10.35" even though it in fact was using 10.36.

1.1.3

• Made in-house streaming abstraction based on streaming and removed the latter as a dependency.
• Updated PCRE2 to 10.36 (no API changes).
• Docs fixes.

1.1.2

• Refactored using the streaming library. Fixed #11, where large global matches were very slow.

1.1.1

• Fixed #12, where some functions returned too many match results.

1.1.0

• Added global matching.
  • New functions matchAll, matchAllOpt, capturesAll, capturesAllOpt.
  • Changed all traversals from affine to non-affine.
• Changed capturesOptA to capturesAOpt for naming consistency.

1.0.2

• Fixed #4, where multiple named captures were not type-indexed correctly.
• Established automated builds using Github Workflows. Thanks amesgen!

1.0.1.1

• Temporarily eliminate all dependency version bounds to get it building on Hackage.

1.0.1

• Fixed #1, where building on Windows would succeed but not run. Thanks Andrew!
• Try to adjust dependency version bounds to get it building on Hackage. Thanks snoyberg!

1.0.0

• Initial release.
