Full Changelog: v6.0.1...v6.0.2

6.0.1

This fixes a showstopper bug in 6.0.0.

Fixed

• Fix import paths to match new major version (#56)

6.0.0

This brings dhall-golang up to version 19.0.0 of the Dhall standard.

Added

• From Dhall 19.0.0: add Text/replace builtin
• Add dhall-golang json command

The new dhall-golang json command takes some Dhall and outputs it as
JSON, similar to dhall-haskell's dhall json. One key difference is
that it also supports Prelude.JSON types. For example, the following
command:

dhall-golang json <<EOF
let JSON = https://prelude.dhall-lang.org/JSON/package.dhall

in  { x = JSON.natural 4
    , y =
        JSON.array
          [ JSON.string "foo", JSON.natural 4, JSON.null, JSON.bool True ]
    }
EOF

will output:

{
  "x": 4,
  "y": [
    "foo",
    4,
    null,
    true
  ]
}

Changed

• From Dhall 19.0.0: implement with as first-class expression
• Allow unmarshalling Dhall values into interface{}; dhall-golang
  will select appropriate Go types for Dhall values when doing this.

5.0.0

This brings dhall-golang up to version 18.0.0 of the Dhall standard.

Changed

• Language changes
  • Enable with optimizations

This implements the newly-possible with optimizations such that
deeply-nested with expressions do not experience pathological
slowdown.

4.1.0

This brings dhall-golang up to version 17.1.0 of the Dhall standard.

Added

• Language changes
  • Allow trailing delmiters (such as trailing commas in lists,
    trailing pipes in unions)

Fixed

• Fix potential panic when typechecking toMap expressions (#49)

4.0.0

This brings dhall-golang up to version 17.0.0 of the Dhall standard.
Again the standard had breaking changes, so this release is a major
version bump.

Thanks to @lisael for their contributions to this release.

Breaking changes

• Language changes:
  • Remove Optional/build and Optional/fold

Added

• Language changes:
  • Allow quoted labels to be empty

Fixed

• Fix potential stack overflow in typechecker (#40)
  • When typechecking certain pathological expressions, the
    typechecker would get into an infinite loop until it exhausted
    the stack.
• Fix error messages when x === y fails to typecheck (#39)

3.0.0

This brings dhall-golang up to version 16.0.0 of the Dhall standard.
As the standard had breaking changes, this release is a major version
bump.

Breaking changes

• Language changes:
  • Adjust precedence of === and with
  • Update encoding of floating point values to RFC7049bis

New features

• Language features:
  • Allow unions with mixed kinds

Bug fixes

• We now save fully-alpha-normalized expressions to the cache (#31)
• We now check the hash of expressions fetched from the cache (#32)

2.0.0

This brings dhall-golang up to version 15.0.0 of the Dhall standard.
As the standard had breaking changes, this release is a major version
bump.

Breaking changes

• added with keyword (technically breaking since you can no longer
  use with as an identifier)

Added

• added record puns (ie { x } is now shorthand for { x = x })
• added UnmarshalFile function (#25)

Changed

• Unmarshal() and Decode() will check a Dhall function matches the
  given Go type before decoding (#23)
• imports are now evaluated at import time (#27)

Fixed

• fixed bug in evaluation of merge (3171f34)

1.0.0

No changes from 1.0.0-rc.4.

1.0.0-rc.4

Another release candidate. There was one more breaking change. I don't anticipate any more breaking changes so if there are no reported issues, this will become 1.0.

Breaking changes

• dhall.Decode() now returns an error instead of panicking (#18)

Changed

• regenerate parser from mna/pigeon master (#16)
• support for unmarshalling into pointer types (#17)
• better encoding of Optional types (#19)
