dhall v1.34.0 Release Notes
Release Date: 2020-08-03 // over 3 years ago-
- 🚀 Supports version 17.1.0 of the standard
- 💥 BREAKING CHANGE to the API: Support prefix comments on record key-value pairs
- The Dhall AST (i.e.
Expr) now preserves some comments for record types
and record literals - The impact of this change is that you will need to add
Dhall.Syntax.makeRecordFieldorDhall.Syntax.recordFieldValuein a few
places wherever your Haskell assembles or disassembles record expressions - The motivation of this change is two-fold:
- To eventually enable
dhall-docssupport for rendering record
📚 comments as documentation - To eventually enable support for preserving record-related comments
when formatting Dhall code
- The Dhall AST (i.e.
- 🐛 BUG FIX: Fix
withexpressions to permit functions on their left-hand side- This was a case of the Haskell implementation not being compliant with the
standard grammar
- This was a case of the Haskell implementation not being compliant with the
- 👍 Drop support for GHC 8.2
- Add a new
dhall rewrite-with-schemascommand- You can now simplify a Dhall expression using a schema record (e.g. a
📦./schemas.dhallrecord that a package might provide) - This simplification replaces large anonymous records with an
equivalent use of a record completion when possible
- You can now simplify a Dhall expression using a schema record (e.g. a
- 👕 Add
--transitiveflag todhall {format,lint,freeze}- This flag lets you format/lint/freeze a file and all of its transitive
dependencies that are reachable via relative file imports
- This flag lets you format/lint/freeze a file and all of its transitive
- 🚚 Move
man/dhall.1todata-files- This ensures that Cabal will install
dhall'smanpages in the
correct directory
- This ensures that Cabal will install
