mirage/irmin 2.2.0

on GitHub

CHANGES:

Added

• irmin:

  • Added Irmin.Type.empty to represent an uninhabited type. (#961, @craigfe)
  • Added Store.Tree.concrete_t. (#1003, @craigfe)

• ppx_irmin

  • Added support for the @nobuiltin attribute, which can be used when
    shadowing primitive types such as unit. See README_PPX for details.
    (#993, @craigfe)

  • Added support for a lib argument, which can be used to supply primitive
    type representations from modules other than Irmin.Type. (#994, @craigfe)

Changed

• irmin:

  • Require OCaml 4.07 (#961, @craigfe)

  • Add sanity checks when creating Irmin.Type records, variants and enums
    (#956 and #966, @liautaud):

    • Irmin.Type.{sealr,sealv,enum} will now raise Invalid_argument if two
      components have the same name;
    • Irmin.Type.{field,case0,case1} will now raise Invalid_argument if
      the component name is not a valid UTF-8 string.

  • Changed the JSON encoding of options and unit to avoid ambiguous cases
    (#967, @liautaud):

    • () is now encoded as {};
    • None is now encoded as null;
    • Some x is now encoded as {"some": x};
    • Fields of records which have value None are still omitted;
    • Fields of records which have value Some x are still unboxed into x.

  • Changed pretty-printing of Irmin types to more closely resemble OCaml types.
    e.g. pair int string prints as int * string. (#997, @craigfe)

  • The type Irmin.S.tree is now abstract. The previous form can be coerced
    to/from the abstract representation with the new functions
    Irmin.S.Tree.{v,destruct} respectively. (#990, @craigfe)

• irmin-mem

  • Stores created with KV now expose their unit metadata type. (#995,
    @craigfe)

Fixed

• irmin-graphql
  • Fixed an issue with keys inside get_{contents,tree} fields having
    incorrect ordering (#989, @craigfe)
