==============

|

|
|
|
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).

## 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][rip].
|
|
|
|
|
|
|
|
|
|
Tvix makes heavy use of rnix-parser in its bytecode compiler. The
|
|
|
|
|
parser is now maintained by Nix community members.
