This adds a new `Dhall.Test.Util.discover` utility for auto-generating
a `TestTree` from a directory tree. This simplifies keeping up to date
with changes to the standard test suite.
- Dhall.Eval: new evaluator, conversion checker and normalizer.
There is no standalone alpha normalizer yet.
- There is a new option "new-normalize" for dhall executable, which uses
the new normalizer.
- Type checker is unchanged.
- new implementation: alphaNormalize, judgmentallyEqual, normalize
- normalizeWith takes a Maybe ReifiedNormalizer argument now, and switches to
the new evaluator whenever the input normalizer is Nothing
- QuickCheck test for isNormalized removed, because we don't support evaluation
of ill-typed terms, which the test would require.
* Use lts-12
* Remove cache on fail and add workaround to fix build with stack
* Add dhall-lsp-server to lts-12
* Commenting out default stack.yaml
* Bump up megaparsec version
* Initial draft of the json-to-dhall tool
* Homogenous JSON maps -> Dhall association lists. Bower example.
* Default conversion options. Ghci examples in function annotations.
* Added type signature to text color highlighting functions (error
reporing)
* Removed TypeApplications extension
* Explicit semigroups
* Disable ghc < 8.0 build
* Type specifications for 'None's (e.g. None Integer instead of just None)
* New style for unions, e.g.: < Left : Text | Right : Integer >.Right +1
This no longer tests dependencies, mainly to lower my maintenance burden. In
particular, this makes it easier for me to test bumping dependencies for
Stackage-related bounds changes.
Some things have changed in the dhall expression tree:
- `let` bindings now take a list of bindings
- `Some` and `None` were introduced
- `Text/show` was added
Additionally, dhall switched to an internal `Map` module instead of
`HashMap.Strict.InsOrd`.
Closes: https://github.com/dhall-lang/dhall-nix/issues/18
... as standardized in https://github.com/dhall-lang/dhall-lang/pull/426
This adds two new `ToTerm`/`FromTerm` classes in order to minimize
code disruption. The main disruption is due to renaming the old
`encode`/`decode` to `encodeExpression`/`decodeExpression`
... as standardized in https://github.com/dhall-lang/dhall-lang/pull/438
This also adds `dhall-json` support for empty alternatives
In particular, this translates empty alternatives to strings encoding the alternative name
```haskell
-- ./example.dhall
let Role = < Wizard | Fighter | Rogue >
in [ Role.Wizard, Role.Fighter ]
```
```
$ dhall-to-json <<< './example.dhall'
["Wizard","Fighter"]
```
... as caught by @singpolyma
`Dhall.Binary.unApply` was failing to uncurry functions due to the presence of
`Note` constructors. This caused `dhall encode` to produce different
results from `dhall hash` since the latter was normalizing the expression
(and therefore removing `Note` constructors) whereas the former was not.

This softens the language to point out that we can't guarantee
that we are secure against malicious expression but we do aim to be
and we don't settle for less.

`--omitEmpty` is the same as `--omitNull` except it also omits fields that
are empty records. To be precise, it omits fields whose transitive fields
are all `null` (and an empty record is a special case of a record whose
transitive fields are all `null` since it is vacuously true when there are
no fields).
This allows Dhall configurations that target YAML to avoid having to nest
sub-records inside of an `Optional` value. Omitting unnecessary `Optional`
layers reduces the number of default values that the configuration format
needs to thread around.
These aren't fully static executables (they still have some
`/nix/store` references), but they at least compile Haskell dependencies
statically. That means that they can be `nix-env --install`ed side-by-side
with other Haskell executables, which would otherwise conflict with an
error like this one:
```

This commit fixes an issue that made the last branch of the completer
unreachable.
The second to last branch was always `True`:
```
> split (== '.') "anything"
["anything"]
```
