0.10.0

Breaking Changes

• Add constant-checking int parsers. Translate calls to intn to get_intn (e.g., int32 becomes get_int32) when migrating to this version. (#139)

Bug Fixes

• Fix error messages in little-endian int parsers (#141)
• Fix bug in <|> operator that did not respect commit points (#146)

Improvements

• Improve documentation of bigstring operations (#145, h/t @dinosaure)
• Allow choice to specify error when all alternatives fail (#143)
• Improve performance of some character parsers (#140)
• Switch to using bigstringaf for bigstring operations (#138)
• Remove references to Oasis build process in README (#137)

v0.9.0

Bugfixes

• Check that the argument to advance is non-negative (#131, h/t @thedufer)
• Properly set the position when calling failure continuations in count_while and count_while1 (#130, h/t @thedufer)
• Fix the js_of_ocaml stubs, so that they actually work. (#133, h/t @martindemello)

API Changes

• Make the continue function returned in the Partial state take an offset and a length. In the process clean up the Input module and remove some redundant checks introduced as part of a previous bugfix. (#123, #129)

Cleanup

• Remove api.odocl, which was a remnant from the Oasis days (#125)
• Compile C code with warnings (#126)
• Add some documentation about the implementation of prompt (#128)

v0.8.1

Optimization and Code Reorganization

• Optimize allocation of char parsers (#112)
• Optimize allocation of *_while parsers (#116)
• Move submodules of Angstrom into their own files (#115)
• Eliminiate use of caml_equals in string parser (#117)
• Fix and/or cleanup benchmarks and tests (#121, #122, #124)

API Changes

• Added Unsafe.peek operation to enable non-allocating or copying lookahead. Should be used in place of peek-string when performance is critical. (#119)

v0.8.0

Bugfixes

• Fix cstubs to use correct integer cast (#107, h/t @hcarty)
• Fix OPAM constraints for async library (#106)
• Fix bug in peek_char that could be triggered by a prompt for more input that did not actually grow the input (#104, h/t @dinosaure)

API Changes

• Added the _bigstring family of functions that can be used like their string-equivalents. Also added an Unsafe module that contains functions that will not perform a copy of the underlying buffer when returning a bigstring. As the name suggests, these functions should be used with caution. (#99, h/t @hcarty).

Performance

• Undo performance caused by the regression in #103 by using bigstring intrinsics rather than caml_ba_get_1 directly (#113)

Improvements

• Make the library -safe-string-compatible (#109, #108)
• Reorganize benchmarks into separate subcommands (#111)

v0.7.0

Breaking Changes

• Remove support for using a string as an internal buffer (#97, #103)
• Remove uint32 and uint64 in favor of the equivalent int32 and int64 (#86)

Other changes

• Eliminate dependency on ocplib-endian (#98)
• Eliminate dependency on cstruct (#96)
• Update README with proper implementation of chain1l (#93)
• Fix version constraint for alcotest dependency (#89, #92)
• Switch to stdless Core and Async (#87)
• Various build fixes from the move over to jbuilder (#88, #100, #101, #102)

v0.6.0

• Remove deprecation warnings related to String.lowercase (#85)
• Fix ocamldoc comments (#84)
• Switch to jbuilder (#70, h/t @rgrinberg)

v0.5.1

• same as 0.5.1 except on the proper release branch, with the right version set

v0.5.0

• Rename rfc directory to examples so examples are to find (#76)
• Fix a validation bug in the json example parser (#77)
• Require OCaml version 4.03 or later (#81)
• Change various equality checks for efficiency and readability (#80)

v0.4.0

Breaking Changes

• Fail states now returns the character position of the parse failure. (#71)
• Done states report the position in the input as their first constructor argument. (#71)
• many_till is now not greedy, meaning it will end after the first time that the termination could have succeeded. (#74) (h/t @mattjbray)

Features

• add scan, scan_state, and scan_string combinators. (#67) (h/t @rgrinberg)
• Copyediting of the README and mli's (#64, #65) (h/t @olleolleolle)

v0.3.0

• add variance annotation to parser type (#62) (h/t @andreas)
