The set of things that can leak out of `builtins` into the global scope is statically known (it is what Nix 2.3 leaks there, essentially). This is a mild change over the previous mechanism, where instead at the point where the `builtins` set is constructed we "lift" the globals out of there (if they exist). This way users will still eventually be able to add additional builtins, HOWEVER they will not be able to leak them into the global scope. Note that upstream Nix technically leaks _all_ builtins into the global scope using the `__*` prefix, but we are trying to avoid this in Tvix if it is not required in nixpkgs.

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.
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.
