- Closes#2089
Now the symbols inside `using {..}` and `hiding {..}` are properly
scoped, which means that they will be properly colored and will have
goto information. If the referenced module does not contain a symbol in
the list, an error will be thrown.
This PR resolves a few bugs in the Makefile targets for formatting and
type checking Juvix files, which were preventing the capture of type
checking errors for our examples and bad formatting for all the Juvix
files in the repository. With this PR, our code should now be clean, and
we can expect every file to be properly formatted and type checked.
Changes made:
- [x] Updated `make format-juvix-files`
- [x] Updated `make check-format-juvix-files`
- [x] Formatted all Juvix files
- [x] Comment a fragment in `examples/milestone/Bank/Bank.juvix`
In the future, we will drastically simplify the Makefile once we improve
the `format` and the `type check` command for example posted here:
- #2066
- #2087
Related:
- #2063
- #2040 (due to some typechecking errors we're not capturing before)
- #2105

* Closes#1965
* Implements the `unroll` pragma to control the unrolling depth on a
per-function basis.
* Implements parsing of the `inline` pragma.

If an import statement to a missing module occurs when parsing in a
project with no dependencies the error message has the following form:
```
The module Foo does not exist.
It should be in /Users/paul/heliax/juvix-2023/tests/negative/NoDependencies/Foo.juvix
or in one of the dependencies:
```
This PR changes this error message to the `or in one of the
dependencies:` line is omitted from the error message when there are no
dependencies in the project.
This commit also adds a negative parse error test for missing module.
This PR adds a builtin integer type to the surface language that is
compiled to the backend integer type.
## Inductive definition
The `Int` type is defined in the standard library as:
```
builtin int
type Int :=
| --- ofNat n represents the integer n
ofNat : Nat -> Int
| --- negSuc n represents the integer -(n + 1)
negSuc : Nat -> Int;
```
## New builtin functions defined in the standard library
```
intToString : Int -> String;
+ : Int -> Int -> Int;
neg : Int -> Int;
* : Int -> Int -> Int;
- : Int -> Int -> Int;
div : Int -> Int -> Int;
mod : Int -> Int -> Int;
== : Int -> Int -> Bool;
<= : Int -> Int -> Bool;
< : Int -> Int -> Bool;
```
Additional builtins required in the definition of the other builtins:
```
negNat : Nat -> Int;
intSubNat : Nat -> Nat -> Int;
nonNeg : Int -> Bool;
```
## REPL types of literals
In the REPL, non-negative integer literals have the inferred type `Nat`,
negative integer literals have the inferred type `Int`.
```
Stdlib.Prelude> :t 1
Nat
Stdlib.Prelude> :t -1
Int
:t let x : Int := 1 in x
Int
```
## The standard library Prelude
The definitions of `*`, `+`, `div` and `mod` are not exported from the
standard library prelude as these would conflict with the definitions
from `Stdlib.Data.Nat`.
Stdlib.Prelude
```
open import Stdlib.Data.Int hiding {+;*;div;mod} public;
```

* Throw error when reading a file that conflicts with stdlib
The Files effect first tries to read a file from the embedded stdlib. If
this succeeds and the file also exists in the project then an error is
thrown.
This error can be thrown either at the parsing stage, if the entrypoint
file conflicts with the standard library, or at the scoping stage if an
imported file conflicts.

In the following case:
```
module WrongConstructorArity;
inductive T {
A : T;
};
f : T → T;
f (A i) ≔ i;
end;
```
The typechecker fails when checking the clause `f (A i) := i` because of
the extra constructor argument. However if typechecking continues then
the variable `i` on the rhs does not have a type so we must short-circuit.
* [ format ] AbstractToMicroJuvix
* [ CI ] fixes
* [ CI ] fixes
* [ CI ] Using GHC 9.0 for Hlint
* [ CI ] Use static-checks for Dev as well
* [test] Add positive test for typechecker
* [test] Improve positive typechecker error output
* [typecheck] Restore correct handling of TypeAny
I mistakenly removed the matchTypes function in
https://github.com/heliaxdev/minijuvix/pull/22. This caused the handling
of TypeAny to break.
Literals have type TypeAny and so should be valid when matching against
any other type. The tests have been updated to reflect this.
* [test] Add positive MicroJuvix typecheck tests
* [ ormolu ] fixes
