Release Date: 2019-12-06 // over 4 years ago-
- 🚀 Supports version 12.0.0 of the standard
- 💥 BREAKING CHANGE: Add
Integer/{clamp,negate}built-ins- This is a technically breaking change API since this adds a new
constructor to theExprtype - This is also a technically breaking change to the language. See the changelog for standard version 12.0.0 for more details
- This is a technically breaking change API since this adds a new
- 💥 BREAKING CHANGE: Remove support for fusion
- This is also a technically breaking change to the language. See the changelog for standard version 12.0.0 for more details
- 💥 BREAKING CHANGE: Parse whitespace more precisely
- The Haskell implementation now matches the official grammar much more
closely, but as a result will now reject some programs that it used to
accept - For example,
1:Naturalused to be valid and now is no longer valid as
the standard requires mandatory whitespace after the: - Consult the standard grammar if you run into a new parsing error as a result of this change
- This is also a parsing performance regression (specifically for parsing
👀 comments), but should not be noticeable in practice. See #1512 for more details
- The Haskell implementation now matches the official grammar much more
- 💥 BREAKING CHANGE: Rename
TypetoDecoderandInputTypetoEncoder#1483 / #1489 - 🐛 BUG FIX: Fix
dhall format --check- Before this change
dhall format --checkwould fail due to attempting to
read all of standard input in twice
- Before this change
- 🐛 BUG FIX: Fix
dhall freezeto always re-freeze an import- Before this fix,
dhall freezewould not attempt to refreeze an already
frozen import
- Before this fix,
- Permit spaces around completion operator
- See the changelog for standard version 12.0.0 for more details
- Make
missingreferentially transparentmissingcan now be imported transitively via a remote import- Normally resolving
missingwould still still fail, except for
missing as Location, which is now a valid transitive import - See the changelog for standard version 12.0.0 for more details
- Write cache files atomically
- This is a resilience improvement so that the cache is not left in a
corrupt state in the event of a power outage or exhausting disk/memory
- This is a resilience improvement so that the cache is not left in a
- New
Dhall.functionutility- This is provides the same functionality as the
Interpretinstance for
(->), except without the use of typeclasses
- This is provides the same functionality as the
- New
dhall haskell-syntax-treecommand- This command displays the Haskell syntax tree of an expression
(primarily for debugging purposes) - Note that this is highly-volatile and subject to change, so don't depend
on this programmatically. We may break the output of this command without
any notice.
- This command displays the Haskell syntax tree of an expression
- Add
instance Show Ann - 🚚 Move normalization code from
Dhall.CoretoDhall.Normalize- Note that this is not a breaking change. The relocated utilities are
still re-exported fromDhall.Core
- Note that this is not a breaking change. The relocated utilities are
