The VM previously took care of repeatedly forcing a thunk until it reached an evaluated state. This logic is now encapsulated inside of the `Thunk::force` implementation. In addition, force no longer returns a reference to the value by default, leaving it up to callers to decide whether they want to borrow the value or not (a helper is provided for this).

Tvix Evaluator
This project implements an interpreter for the Nix programming language.
The interpreter aims to be compatible with nixpkgs
, on the
foundation of Nix 2.3.
Work on this project is extremely in-progress, and the state of the project in the public repository may not necessarily reflect the state of the private codebase, as we are slowly working on publishing it.
We expect this to have caught up in a handful of weeks (as of 2022-08-12).
Please contact TVL with any questions you might have.
Nix test suite
C++ Nix implements a language test suite in the form of Nix source code files, and their expected output. The coverage of this test suite is not complete, but we intend to be compatible with it.
We have ported the test suite to Tvix, but do not run it by default as we are not yet compatible with it.
You can run the test suite by enabling the nix_tests
feature in
Cargo:
cargo test --features nix_tests
rnix-parser
Tvix is written in memory of jD91mZM2, the author of rnix-parser who sadly passed away.
Tvix makes heavy use of rnix-parser in its bytecode compiler. The parser is now maintained by Nix community members.
