package yaml

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/pkg.ml 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)
