This PR adds some maintenance at different levels to the CI config, the
Make file, and formatting.
- Most of the actions used by the CI related to haskell, ormolu, hlint
and pre-commit have been updated because Github requires NodeJS 16. This
change removes all the old warnings related to nodeJs.
In the case of ormolu, the new version makes us format some files that
were not formatted before, similarly with hlint.
- The CI has been updated to use the latest version of the Smoke testing
framework, which introduced installation of the dependencies for Linux
(libicu66) and macOS (icu4c) in the CI. In the case of macOS, the CI
uses a binary for smoke. For Linux, we use stack to build smoke from the
source. The source here is in a fork of [the official Smoke
repo](https://github.com/SamirTalwar/smoke). Such includes some
features/changes that are not yet in the official repo.
- The Makefile runs the ormolu and hlint targets using as a path for the
binaries the environment variables ORMOLU and HLINT. Thus, export those
variables in your environment before running `make check,` `make format`
or `make hlint`. Otherwise, the Makefile will use the binaries provided
by `stack`.

We need to use the homebrew Clang/LLVM installation to build the Juvix
runtime because macOS ships with a version of Clang/LLVM that does not
support the wasi target.
The GitHub action runner agent has the homebrew packaged Clang/LLVM
installed but it is not on the shell PATH.
We were using `brew --prefix llvm@14` to point to the homebrew
Clang/LLVM installation. However this breaks when the runner image is
updated to a new version of llvm.
So we switch to using `brew --prefix llvm` which will resolve to the
latest (and in this case only) version of homebrew Clang/LLVM. This will
be stable when Clang/LLVM is updated to a new version.

The tutorial uses syntax which has not been implemented yet: it depends
on
- #1637,
- #1716,
- #1639,
- #1638.
The tutorial also assumes the following issues are done:
- #1720, and
- #1701.

This PR redefines the `html` command unifying our previous subcommands
for the HTML backend. You should use the command in the following way to
obtain the same results as before:
- `juvix html src.juvix` -> `juvix html src.juvix --only-source`
- `juvix dev doc src.juvix` -> `juvix html src.juvix`
- Other fixes here include the flag `--non-recursive`, which replaces
the previous behavior in that we now generate all the HTML recursively
by default.
- The flag `--no-print-metadata` is now called `--no-footer`
- Also, another change introduced by this PR is asset handling; for
example, with our canonical Juvix program,
the new output is organized as follows.
```
juvix html HelloWorld.juvix --only-source && tree html/
Copying assets files to test/html/assets

In addition, for the vscode-plugin, this PR adds two flags,
`--prefix-assets` and `--prefix-url`, for which one provides input to
help vscode find resource locations and Juvix files.
PS. Make sure to run `make clean` the first time you run `make install`
for the first time.
The internal to core translation was removing implicit arguments from
function definitions and applications. This is incorrect as the implicit
bindings are required when translating the following (in `csuc`, the
binding of the implicit argument is required in an application on the
rhs):
```
Num : Type;
Num := {A : Type} → (A → A) → A → A;
csuc : Num → Num;
csuc n {_} f := f ∘ n {_} f;
```
Apart from removing this filter from function and application
translation, this required the following changes:
ConstructorInfo:
The _constructorArgsNum field must include the number of type parameters
of its inductive type.
PatternConstructorApp:
The pattern arguments must include wildcards for the implicit type
parameters passed to the constructor.
BuiltinIf:
The BuiltinIf expression is passed an implicit type argument that must
be removed when translating to Core if.
LitString:
A literal string is a function with an implcit type argument. So this
must be a translated to a lambda where the type argument is ignored.
Fixes https://github.com/anoma/juvix/issues/1714
A lambda:
```
\ { v0 := b0 ; v1 := b1 ; ... ; vn := bn }
```
should be translated to:
```
λ? (λ? ... (λ? (match ?$0, ?$1, ... , ?$n with ...)))
```
i.e the de Brujin index of the values in the match always start from 0.
Fixes: https://github.com/anoma/juvix/issues/1695
This pr removes wildcard patterns from the Internal language.
Wildcards are translated to variables with generated names.
This should resolve the issue of having unbound names after inference
Adds Juvix tests for the compilation pipeline - these are converted from
the JuvixCore tests (those that make sense). Currently, only the
translation from Juvix to JuvixCore is checked for the tests that can be
type-checked. Ultimately, the entire compilation pipeline down to native
code / WebAssembly should be checked on these tests.
Closes#1689
Closes#1483
The error now points to the offending `=`, works correctly with
multi-line clauses, and explains exactly what's wrong. E.g. for
```agda
f : Nat → Nat → Nat;
f zero x = x;
```
we get
```
|
6 | f zero x = x;
| ^
expected ":=" instead of "="
```
A minor disadvantage of the proposed solution is that now it's
impossible to use `=` without parentheses as a top variable name in a
pattern, e.g.
```
f zero = := =;
```
gives an error.
However, if one really wants to name a variable `=`, it is enough just
to enclose it in parentheses:
```agda
f : Nat → Nat → Nat;
f zero (=) := =;
f (suc n) (=) := f n =;
```
I believe this slight non-uniformity is well worth the increased
usability due to a better error message. Confusing `:=` with `=` is very
common. Using `=` as a variable name in a top pattern is rare.

This PR adds smoke tests using [Smoke
tool](https://github.com/SamirTalwar/smoke) for all the shell tests we
have. One reason for adopting Smoke instead of the previous tool,
`shelltestrunner`, is that tests are declared cleanly and simply using
Smoke Yaml syntax compared to shelltestrunner's syntax.
To add a new smoke test, create a file with the suffix ".smoke.yaml" in
the `tests/smoke` folder. In such a folder, you can also find examples
of how to test the CLI.
An implementation of the translation from JuvixCore to JuvixAsm. After
merging this PR, the only remaining step to complete the basic
compilation pipeline (#1556) is the compilation of complex pattern
matching (#1531).
* Fixes several bugs in lambda-lifting.
* Fixes several bugs in the RemoveTypeArgs transformation.
* Fixes several bugs in the TopEtaExpand transformation.
* Adds the ConvertBuiltinTypes transformation which converts the builtin
bool inductive type to Core primitive bool.
* Adds the `juvix dev core strip` command.
* Adds the `juvix dev core asm` command.
* Adds the `juvix dev core compile` command.
* Adds two groups of tests:
- JuvixCore to JuvixAsm translation: translate JuvixCore tests to
JuvixAsm and run the results with the JuvixAsm interpreter,
- JuvixCore compilation: compile JuvixCore tests to native code and WASM
and execute the results.
* Closes#1520
* Closes#1549
* Fixes#1678.
* Adds the `clean-juvix-build` Makefile target, which removes all
`.juvix-build` directories in the project (necessary to do after
changing the standard library).
* Depends on PR #1688. The tests go through without merging this PR, but
it's a bug. The present PR requires the possibility to use the
`terminating` keyword with the `div` built-in, which possibility is
provided by PR #1688.
This PR implements `printString` and `printBool` builtins for the legacy
C backend. Previously IO for strings was done using compile blocks with
included C code.
