Fixes https://github.com/dhall-lang/dhall-haskell/issues/1470
`dhall freeze` no longer attempts to use the cache to fetch an import since
the cache might not match the underlying import any longer. Instead,
`dhall freeze` now always attempts to fetch the underlying import to
compute the new hash.
* Resolve#1451: fix `format --check` given STDIN input.
I'm not really sure if this is the "best" approach so let me know if you
know a way to simplify this.
The issue was that `getExpressionAndHeader` was doing a second
`IO.getContents` (thus reading STDIN twice).
* Rename `Input` constructor.
If you run `dhall --explain` to explain a type error from a list with
mismatched elements, the index of the offending term was wrong. For a
minimal example, you can run:
dhall --explain <<<'[0, True]'
The problem is that `i` is an index into the tail of the list, not into
the whole list. The fix is just to add one to it to correct for the
missing head.
* Update `Dhall.Tutorial` module
This overhauls the `Dhall.Tutorial` module to reflect recent changes to
the language (and also to link to external documentation when possible).
* Fix doctests

... as suggested by @sjakobi

* Rename Interpret to FromDhall
The "Interpret" name remains in `InterpretOptions`, which are
actually used for marshalling in both directions.
* s/injectThenInterpretIsIdentity/embedThenExtractIsIdentity
* s/Inject/ToDhall
* s/shouldInjectInto*/shouldEmbedAs*
* Keep Interpret and Inject as constraint synonyms for compatibility
… as suggested by @Gabriel439.
The "builtins.fetchTarball" function is not available in some restricted
environments such as build jobs of the latest Hydra. Make it possible to
pass nixpkgs and nixpkgsStaticLinux when evaulating default.nix and
release.nix to avoid importing them internally. This does not change the
result of evaulation if no parameters are passed.
* Move prefix out of renderSrc
This reduces the complexity of renderSrc slightly without affecting
anything else much.
* Make formatting of comments idempotent
Fixes#1413. Previously the formatter would insert an additional line
break before some comments whilst preserving existing line breaks. In
order to restore idempotent behaviour, we need to strip a leading
newline character from the comment string in those cases, if present.
* Test idempotency when formatting comments
Test case taken from @AJChapman's bug report (#1413).
* Change argument order of renderSrc
Reads a bit more idiomatic, as suggested by @sjakobi.
* [#1392] Injecting Data.Map
* injecting via Generic
* Explicit instance

* Update dhall/dhall.cabal

This updates the `dhall` package to have 100% haddock coverage and
also updates CI to enforce this going forward.
This also includes a change to deprecate the `X` type synonym, which
I noticed along the way

* Add support for leading separators
... as standardized in https://github.com/dhall-lang/dhall-lang/pull/755
Note that this does not yet change the formatter to use them

Related to https://github.com/dhall-lang/dhall-haskell/issues/1356#issuecomment-536840612
* Specify utf8 encoding for tests
* Add test for hovering functionality
* Add glob to list fixture files
* Remove extra do
* Resolves#1408: Add more detail in `--explain` when `toMap` has the wrong type.
Specifically, add common reason of using `{}` for record value.
For example,
``` shell
echo 'toMap {}' | ~/.local/bin/dhall
```
Outputs
> Error: ❰toMap❱ expects a record value
>
> Explanation: You can apply ❰toMap❱ to any homogenous record, like this:
>
>
> ┌─────────────────────────────────────────────────────────────────────┐
> │ let record = { one = 1, two = 2 }
> │
> │ in toMap record : List { mapKey : Text, mapValue : Natural}
> │
> └─────────────────────────────────────────────────────────────────────┘
>
>
> ... but the argument to ❰toMap❱ must be a record and not some other
> type.
>
> Some common reasons why you might get this error:
>
> ● You accidentally provide an empty record type instead of an empty
> record when
> using ❰toMap❱:
>
>
> ┌──────────┐
> │ toMap {} │
> └──────────┘
> ⇧
> This should be ❰{=}❱ instead
>
> ────────────────────────────────────────────────────────────────────────────────

> 1│ toMap {}

* Add type annotation to `toMap` suggestion.
* #1381 Word* to Natural
* Added instance for Word
* Got rid of linting issues
* Added docsets
* Added comments
* Revert Crypto to master version
* Spread the doctests
* Improve Docstring
This includes some simplifications/optimizations for the `ToTerm DhallDouble` instance.
Most notably we let `cborg` take care of the correct encoding of NaNs:
