CHANGES.md.html

2.1.0

2023-04-26

Added

  • Add Yojson.Raw.Util module to provide combinators for extracting fields from Yojson.Raw.t values. (@tmcgilchrist, #163)

  • Add Util.path function to recurse into an object through a list of keys. (@cuihtlauac, @Leonidas-from-XIV, #157)

2.0.2

2022-08-09

Added

  • Expanded documentation of exceptions (@sim642, #148)

Removed

  • Removed undocumented and unused functions write_float_fast and write_std_float_fast from Yojson, Yojson.Basic and Yojson.Safe (@sim642, #149)

Fixed

  • Fix out-of-bounds error occurring when parsing object field names with atdgen parsers using map_ident or map_lexeme (@mjambon, #150)

2.0.1

2022-06-28

Fixed

  • Fix pretty-printing behavior for lists/objects inside lists (@c-cube #141, @mjambon #142)

2.0.0

2022-06-02

Removed

  • Removed dependency on easy-format and removed pretty_format from Yojson, Yojson.Basic, Yojson.Safe and Yojson.Raw. (@c-cube, #90)

  • Removed dependency on biniou, simplifying the chain of dependencies. This changes some APIs:

    • Bi_outbuf.t in signatures is replaced with Buffer.t

    • to_outbuf becomes to_buffer and stream_to_outbuf becomes stream_to_buffer (@Leonidas-from-XIV, #74, and @gasche, #132)

  • Removed yojson-biniou library

  • Removed deprecated json type aliasing type t which has been available since 1.6.0 (@Leonidas-from-XIV, #100).

  • Removed json_max type (@Leonidas-from-XIV, #103)

  • Removed constraint that the "root" value being rendered (via either pretty_print or to_string) must be an object or array. (@cemerick, #121)

  • Removed validate_json as it only made sense if the type was called json. (@Leonidas-from-XIV, #137)

Add

  • Add an opam package yojson-bench to deal with benchmarks dependency (@tmcgilchrist, #117)

  • Add a benchmark to judge the respective performance of providing a buffer vs letting Yojson create an internal (#134, @Leonidas-from-XIV)

  • Add an optional suf keyword argument was added to functions that write serialized JSON, thus allowing NDJSON output. Most functions default to not adding any suffix except for to_file (#124, @panglesd) and functions writing sequences of values where the default is \n (#135, @Leonidas-from-XIV)

Change

  • The stream_from_* and stream_to_* functions now use a Seq.t instead of a Stream.t, and they are renamed into seq_from_* and seq_to_* (@gasche, #131).

Fix

  • Avoid copying unnecessarily large amounts of strings when parsing (#85, #108, @Leonidas-from-XIV)

  • Fix stream_to_file (#133, @tcoopman and @gasche)

1.7.0

2019-02-14

Add

  • Add documented write_t and read_t to modules defining a JSON ast type for compatibility with atdgen

1.6.0

2019-01-30

Deprecate

  • json types are deprecated in favor of their new t aliases, ahead of their removal in the next major release (#73, @Leonidas-from-XIV)

Add

  • Add a type t and monomorphic equal, pp and show (#73, @Leonidas-from-XIV)

1.5.0

Change

  • Use dune as a build system (#67, @Leonidas-from-XIV)

  • reraise exceptions in finish_string instead of silencing them by raising a Failure _

  • raise finalizer exceptions in from_channel and from_lexbuf readers

Fix

  • Fix a race condition in builds (#57, @avsm)
