Dune Dependency





v3.2.0 (04/111/2023)

  • Fix potential GC corruption when serialising large Yaml buffers (#75 @hhugo)

  • Add missing ?len argument to yaml_of_string to specify buffer size (#74 @hhugo)

  • Remove remaining references to Rresult in tests and documentation (#62 @sim642)

v3.1.0 (27/03/2022)

  • Support MSVC with .obj and .lib extensions, and defining -DDYAML_DECLARE_EXPORT (@jonahbeckford #53)

  • Upgrade to dune 2 (@TheLortex, #54)

  • Add ocamlformat (@samoht, #55)

  • Make yaml compatible with opam-monorepo (@TheLortex, #56)

v3.0.1 (04/02/2022)

  • Remove dependency on Rresult (@maxtori #50).

v3.0.0 (04/08/2021)

  • Support Yaml 1.2, and stop advertising Yaml 1.0 support. This also updates the vendored libyaml to 0.2.5 (@favonia #37).

  • Add a Yaml.Util module with a number of useful combinators to manipulate Yaml.value types, such as retrieving keys and values, finding entries and converting to OCaml native types (@patricoferris #43)

  • Move the sexpression derivers into a separate Yaml_sexp package (the yaml-sexp opam package). This reduces dependencies on the main library. You can still use Yaml types in ppx_sexplib_conv derivers by simply replacing the Yaml.value (or other type) with Yaml_sexp.value which is an alias that also includes the Sexp conversion functions in its scope. (@alan-j-hu @avsm #46).

  • When outputting values, wrap special values like "true" or "1.0" in double quotes, so that Yaml.of_string will not interpret them as a non-string value (@avsm #47).

  • Track anchors and mappings in Yaml.yaml (but not in the Yaml.value JSON representation). This also allows non-scalar values to be used as keys. (@favonia #38)

  • Bump the internal write buffer for stream emission to 256k from 64k, as people are writing ever-larger Yaml files! In the future, this static buffer will be replaced by a dynamically growing output buffer but for now needs to be set manually.

  • The minimum supported OCaml version is now OCaml 4.05.

v2.1.0 (07/02/2020)

  • Fix a memory unsoundness issue with larger files in the bindings to libyaml, which fixes spurious errors when parsing larger YAML files (#35 marcinkoziej)

  • Expose more information about error locations while parsing a Yaml file (#34 @marcinkoziej)

  • Add test for a large Yaml file (#30 @pmonson711)

  • Bump size of internal serialisation buffer in to_string to 64KB from 16KB (@avsm).

  • Switch CI to GitHub Actions (@avsm)

  • Depend on dune-configurator in the build to be compatible with dune 2.0 and higher (@avsm)

v2.0.1 (18/08/2019)

  • Add unexpected error codes to error messages so that debugging errors from libyaml is possible (#28 @mjambon)

v2.0.0 (24/03/2019)

  • Represent quoted scalars as strings in Json encoding (#22 @rizo, fixes #20).

  • Expose more detailed scalar information in Yaml.yaml (#22 @rizo).

  • Add Yaml.equal (#22 @rizo)

  • Avoid printing the decimal point when the float number is an integer (#25 @kit-ty-kate)

v1.0.0 (17/02/2019)

  • Support parsing of canonical Yaml null, float and bool values (@avsm, fixes #15 #16).

  • Port from jbuilder to dune (#2 @rgrinberg)

  • Use dune.configurator for config probing (#18 @emillon)

  • Upgrade opam metadata to 2.0 format (@avsm)

  • Suppress some C warnings on build due to ctypes autogen until ctypes gains support for unsigned char types (@avsm)

  • Add Windows build support (@avsm #11)

  • Refresh libyaml to upstream changeset 85d1f168ef39f4 (@avsm)

  • Switch CI to Azure Pipelines and test Windows, Linux and macOS (@avsm)

  • Add Junit output to the Alcotest (@avsm)

v0.2.1 (01/06/2018)

  • Repair build on ppc64le by using Configurator to query CFLAGS. ppc64le needs an mcmodel=small due to a quick of the architecture.

  • Minor improvements to ocamldoc documentation.

  • Remove pkg/ as dune-release is used for release now.

v0.2.0 (17/05/2018)

  • Explicitly depend on sexplib in jbuild description.

  • Remove use of deprecated build variables in jbuild file.

  • Add a Yaml_unix module with functions to read and write from files directly.

  • Eliminate runtime dependency on Str (#10 from @yallop)

  • Various build fixes (#9 #8 #7 from @diml @rgrinberg).

v0.1.0 (24/12/2017)

  • Initial public release.
