2022-12-21 r/5440 refactor(tvix): split binary (REPL etc.) out from evaluator libraryVincent Ambo1-106/+0
The tvix-eval project is independent from any *uses* of the evaluator, such as the tvix-repl. This functionality has been split out into a separate "tvix-cli" crate. Note that this doesn't have to mean that this CLI crate is the "final" CLI crate for tvix, the point of this is not "getting the CLI structure right" but rather "getting the evaluator structure right". This reshuffling is part of restructuring the way that functionality like store communication is injected into language evaluation. Note that at this commit the new CLI crate is not at feature-parity.

2022-10-11 r/5103 feat(tvix/eval): Allow directly evaluating an expr via mainGriffin Smith1-0/+7
This *maybe* should do something to check that we don't pass both a file and an expr, but for now this is useful enough to cut corners (plus we're probably due for a CLI revamp eventually anyway).

2022-10-10 r/5087 feat(tvix/eval): Initial resolution of `<...>` pathsGriffin Smith1-1/+1
This commit implements (lazy) resolution of `<...>` paths via either the NIX_PATH environment variable, or the -I command-line flag - both handled via EvalOptions. As a result, EvalOptions can no longer derive Copy, meaning we have to clone it at each line of the repl - this is probably not a huge deal as repl performance is not exactly an inner loop and we're not cloning very much. Internally, this works by creating a thunk which pushes a constant containing the string inside the brackets to the stack, then a new opcode to resolve that path via the `NixPath`. To get that opcode to work, we now have to pass in the NixPath when constructing the VM. This (intentionally) leaves out proper implementation of path resolution via `findFile` (cppnix just calls whatever identifier called findFile is in scope!!!) as that's widely considered a bit of a misfeature, but if we do decide to implement that down the road it likely wouldn't be more than a few extra ops within the thunk introduced here.

2022-09-18 r/4911 refactor(tvix/eval): use Clap for arg+env parsingGriffin Smith1-14/+19
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`.

We may want to warn about it, but in general this sort of non-essential feature should not cause a hard failure.

Add a new `lib.rs` to tvix/eval, which `pub use`s the `interpret` function, and all types mentioned in its return type, and then uses *this* instead of direct `mod` statements in the `main.rs` to implement the entrypoints to the interpreter. This is in preparation for calling these functions from integrated benchmarking infrastructure using Criterion, though other things (like integration tests) might want to do that as well.
