• Support new Text/replace built-in

1.7.2

• The --documents flag now wraps non-Lists in a document

1.7.1

• Format documents with leading ---
  • Now if you use the --documents flag the first document will also include a leading ---

1.7.0

• BREAKING CHANGE: Add --generated-comment flag for dhall-to-yaml{-ng}
  • You can now optionally add a comment header to the YAML output indicating that the file is generated and should not be hand-edited
  • This is a breaking change because this adds a new noEdit field to the options type
  • In practice this breakage won't affect most users
• Produce output compatible with YAML 1.1
  • Special strings like on are now quoted in order to avoid being misinterpreted as boolean values by YAML 1.1 implementations
• Show JSON/YAML path on error reporting
  • Error messages will now include the path to the error in the diagnostic output

1.6.4

• Add json-to-dhall support for inferring the schema
  • You no longer need to provide the command with an explicit schema. The command will infer a reasonably close schema from the provided JSON
• Add json-to-dhall type subcommand
  • You can use this subcommand to print the inferred schema for a JSON value, so that you can edit the schema and use it for subsequent invocations.
• Add json-to-dhall support for using toMap
  • Now if you specify a Map as the schema, the generated Dhall code will use toMap to improve the appearance

1.6.3

• yaml: Single-quote date/bool string fields

1.6.2

• Fix dhall-json for new Prelude.JSON.Type
  • Version 13.0.0 of the Prelude caused the JSON type to change, which broke dhall-json's support for that type
  • This release fixes that (and still supports the old JSON type)

1.6.1

• Fix typos in error messages

1.6.0

• BREAKING CHANGE: Move HsYAML code to a new dhall-yaml package
  • This package is now fully BSD-licensed (both for the JSON and YAML utilities)
  • The GPL-licensed YAML utilities are now provided as part of the dhall-yaml package
  • Note that this package still provides dhall-to-yaml and the dhall-yaml package provides a separate dhall-to-yaml-ng executable
  • This is a breaking change in the following respects:
    • The YAML-related modules in this package were renamed
    • This package no longer accepts a -fgpl cabal configure flag
    • This package no longer provides the yaml-to-dhall executable (which now resides within the dhall-yaml package)
• BREAKING CHANGE: Rename some options of dhall-to-{json,yaml} to more consistent ones:
  • rename --omitEmpty to --omit-empty
  • rename --preserveNull to --preserve-null
  • rename --noMaps to --no-maps
  • drop --omitNull as redundant because of --preserve-null (see below)
• BUG FIX: Handle empty maps correctly
  • dhall-to-{json,yaml} now correctly translate empty Dhall maps to empty JSON dictionaries
• Add Dhall.JSON.defaultConversion
• Don't normalize schema before type-checking
  • This improves the error messages for {json,yaml}-to-dhall
• Fix dhall-to-yaml to quote special strings
• Make some of CLI options for dhall-json more consistent

1.5.0

• BREAKING CHANGE: Enable --pretty by default for dhall-to-json
• BREAKING CHANGE: Enable --omitNull by default for dhall-to-{json,yaml}
  • To recover the old behavior use the --preserveNull flag
• Add support for building against the HsYAML package #1248 / #1417 / #1420
  • To enable the use of HsYAML, enable the -fgpl cabal configure flag, which means that anything built using that flag is GPLv3 licensed
  • By default dhall-json builds against aeson-yaml which is BSD-3 licensed
  • The yaml-to-dhall executable is only available with the -fgpl flag, meaning that it is necessarily GPLv3 licensed
• New --omissible-lists flag for {json,yaml}-to-dhall
  • This flag is sort of the inverse of the --omitEmpty flag, meaning that missing YAML/JSON lists can be translated to present (but empty) Dhall lists

1.4.1

• Enable --records-strict by default for {json-yaml}-to-dhall
• Fix --file flag for dhall-to-{json,yaml}
• Fix --version flag for {yaml,json}-to-dhall
• Nesting: Support empty alternatives as contents
• Fix yaml-to-dhall support for empty objects
• Throw error when union value is incompatible with inline nesting
• Add --output options
• Minor bug fixes for yaml-to-dhall error messages

1.4.0

• BREAKING CHANGE: Split Dhall.YAML into Dhall.YAML + Dhall.YAMLToDhall
  • See: #993
• BUG FIX: Fix dhall-to-{json,yaml}'s support for preserving alternative names
  • The Nested/Inline unions are now correctly given special treatment again
  • See: #1080
• Feature: Support weakly-typed JSON value added to Prelude
  • You can now encode/decode values of type ./Prelude/JSON/Type which can store arbitrary JSON
  • This is useful when dealing with "pass-through" or schema-free JSON values
  • See: #1007
• Feature: Eta support for dhall-json
  • See: #1013
• Feature: Add --file option to dhall-json executables
• Feature: Support unions for keys
  • You can now decode record fields as enums instead of Text so that you can pattern match on them
  • See: #1094
• Pretty-print output of {json,yaml}-to-dhall
  • See: #1150

1.3.0

• BREAKING CHANGE: Change YAML/JSON encoding for NaN/Infinity/-Infinity
  • They are now encoded as the standard "nan"/"inf"/"-inf" representations instead of null/MIN_DOUBLE//MAX_DOUBLE
  • See: #946
• BREAKING CHANGE: Isolate YAML code to one modulee
  • This is a breaking change because it moves Dhall.JSON.jsonToYaml to Dhall.YAML.jsonToYaml
  • See: #989
• New yaml-to-dhall command-line utility
  • See: #977
• Add --quoted flag to force quoting of YAML string literals
  • See: #941

1.2.8

• New json-to-dhall command-line utility

  • See: #895
  • See: #900

1.2.7

• Build against dhall-1.21.0
• Support GHC 7.10.3
  • See: #814
• Add new --omitEmpty flag for omitting nulls and empty records

1.2.6

• Add --version flag
  • See: #704
• Build against tasty-1.2
  • See: #731
• Add --compact flag to dhall-to-json
  • Eventually --pretty will become the default, so this flag provides a way for a user to preserve the old 1-line output when that happens
  • See: #743

1.2.5

• Build against dhall-1.19.0
  • See: #667
  • See: #675
  • See: #689

1.2.4

• New dhall-to-yaml --documents flag for generating split documents
  • See: dhall-lang/dhall-json#59
