2022-09-20 r/4944 feat(tvix/eval): track other type in NotCallable error kindVincent Ambo2-6/+9
This makes for slightly nicer error messages if something isn't, well, callable. Change-Id: I821c8d7447b93aea9ccaaa52ed329de0cca4b18e Reviewed-on: https://cl.tvl.fyi/c/depot/+/6718 Tested-by: BuildkiteCI Reviewed-by: sterni <sternenseemann@systemli.org>
2022-09-20 r/4943 refactor(tvix/eval): add VM::call_value helper methodVincent Ambo5-34/+32
This makes it possible to call a callable value (builtin or closure/lambda) directly, without unwrapping it first. This is needed for pretty much all higher-order functions to work correctly. This is mostly equivalent to the previous code in coerce_to_string for calling `__toString`, except it expects the argument(s) to already be placed on the stack. Note that the span for the `NotCallable` error is not currently guaranteed to make any sense, will experiment with this.

2022-09-20 r/4941 feat(tvix/eval): implement builtins.mapVincent Ambo4-1/+43
As we already have a VM passed to the builtins, we can simply execute the provided closure/lambda in it for each value. The primary annoyance with this is that we have to clone the upvalues for each element, but we can try making this cheaper in the future (it's also a general problem in the VM itself).

2022-09-18 r/4908 refactor(tvix/eval): Don't (ab)use PartialEq for Nix equalityGriffin Smith11-118/+196
Using rust's PartialEq trait to implement Nix equality semantics is reasonably fraught with peril, both because the actual laws are different than what nix expects, and (more importantly) because certain things actually require extra context to compare for equality (for example, thunks need to be forced). This converts the manual PartialEq impl for Value (and all its descendants) to a *derived* PartialEq impl (which requires a lot of extra PartialEq derives on miscellanious other types within the codebase), and converts the previous nix-semantics equality comparison into a new `nix_eq` method. This returns an EvalResult, even though it can't currently return an error, to allow it to fail when eg forcing thunks (which it will do soon). Since the PartialEq impls for Value and NixAttrs are now quite boring, this converts the generated proptests for those into handwritten ones that cover `nix_eq` instead Change-Id: If3da7171f88c22eda5b7a60030d8b00c3b76f672 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6650 Autosubmit: grfn <grfn@gws.fyi> Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>

This disconnects ownership of the `File` reference in a compiler from the calling scope, which is required for when we implement `import`. `import` will need to carry an `Rc<RefCell<CodeMap>>` (or maybe, in the future, Arc) to give us the ability to add new detected code files at runtime. Note that the choice of `Arc` over `Rc` here is not ours - it's the codemap crate's.

2022-09-17 r/4886 test(tvix/eval): Add the start of a nix oracle test suiteGriffin Smith4-30/+165
Add the start of a test suite that compares tvix eval results against nix, using the string repr of the value as the comparison. This shells out to a nix-instantiate binary, which is configurable as an environment variable, to eval - there's some extra machinery there to setup a new nix store as a tempdir to allow running this test inside the nix build for tvix-eval itself. Currently this has a macro that'll allow writing lots and lots of hardcoded tests, but going forward I'm also going to be looking into adding proptest-based generation of expressions to compare.

2022-09-17 r/4883 feat(tvix/eval): introduce `ToSpan` trait in compiler moduleVincent Ambo2-18/+96
This trait can be used to convert most structures from rnix-parser into a codemap::Span. It uses a macro to implement the trait for the various expression types in the rnix AST, as Rust's silly semantic versioning restriction stops us from doing a blanket implementation. This will be used in the next commit to clean up the span handling in the compiler a bit.
