2022-11-08 r/5263 feat(tvix/eval): Add a proc-macro for defining builtinsGriffin Smith1-0/+1
Add a single new proc macro to a new proc-macro crate, `tvix-eval-proc-macros` for defining an inline module containing nix builtins, and automatically generating a function within that module which returns a list of those builtins as `tvix_eval::value::Builtin`.

2022-10-16 r/5143 feat(tvix/eval): add an AST pretty-printing moduleVincent Ambo1-1/+2
This implements serde::Serialize for the rnix AST through a wrapper type, and exposes a function for serialising the AST into a (pretty-printed JSON) string representation. This can be used to debug issues with the AST, and to display an AST reprsentation in tools like tvixbolt. Serialize is implemented manually because we don't own any of the structs and the way to traverse them is not easily derived automatically, and this is quite verbose. We might be able to condense it a little bit, but at the same time it's also fairly straightforward.

2022-10-15 r/5136 feat(tvix/eval): Initial impl of builtins.matchGriffin Smith1-0/+1
Implement an *initial* version of builtins.match, using the rust `regex` crate for regular expressions. The rust regex crate definitely has different semantics than nix's regular expressions - but we'd like to see how far we can get before the incompatibility starts to matter. This consciously leaves out any sort of memo for compiled regular expressions (which upstream nix also has) for the sake of expediency - in the future we should implement that so we don't have to compile the same regular expression multiple times.

Using `serde_json` for parsing JSON here, plus an `impl FromJSON for Value`. The latter is primarily to stay "dependency light" for now - likely going with an actual serde `Deserialize` impl in the future is going to be way better as it allows saving significantly on intermediary allocations.

2022-09-22 r/4958 fix(tvix/eval): support string identifiers in inheritsVincent Ambo1-2/+2
This updates rnix-parser to a version where inherits provide an iterator over `ast::Attr` instead of `ast::Ident`, which mirrors the behaviour of Nix (inherits can have (statically known) strings as their identifiers). This actually required some fairly significant code reshuffling in the compiler, as there was an implicit assumption in many places that we would have an `ast::Ident` node available when dealing with variable access (which is then explicitly only not true in this case).

Refactor the environment variable and argument parsing for the tvix repl to use Clap instead of doing things ad-hoc, and thread through options obtained from environment variables via explicit arguments rather than obtaining them from the environment as they're needed. This makes adding more flags more sustainable, and also makes the binary fully self-documenting, including supported env vars, via `--help`.

It's proptest time! Add deps on the proptest and test_strategy crates, gated behind a new (default-enabled) "arbitrary" feature flag so that they don't affect dependencies of things like tvixbolt that depend on tvix. These are going in dependencies, not dev-dependencies, so that we can impl Arbitrary for stuff outside of test modules (which will be important for integration suites which want to run proptests) Change-Id: I1613bd3ea9a835e22986ad4e59700e8736007963 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6624 Autosubmit: grfn <grfn@gws.fyi> Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>
2022-09-17 r/4886 test(tvix/eval): Add the start of a nix oracle test suiteGriffin Smith1-0/+1
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.

This will be used to track source spans when emitting bytecode. The codemap is a data structure which tracks *all* the source files visited by an evaluation, and makes it possible to represent locations across all of the files using a simple span (i.e. pair of offsets). When reporting errors, this even contains enough information to reconstruct the rnix AST to create fancier reporting in certain cases if desired.

2022-09-01 r/4567 refactor(tvix/eval): Upgrade to latest rnix-parserVincent Ambo1-1/+7
Since the latest published version of rnix-parser on crates.io, the crate has undergone major changes which are only available in the git repository at the moment. This commit updates the compiler to this newer version of rnix. Most notably, the entire AST provided by rnix is now wrapped in the AST type system. As a result of this traversal is much nicer in many places, especially for things like nested attribute selection. There are a handful of smaller features missing for full feature parity with the previous version, especially handling of path literals, but PRs for these already exist in rnix-parser.

Additionally smol_str is already in the dependency graph because rnix uses it, and using it for representations of identifiers is sensible.
