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.

2022-10-08 r/5070 feat(tvix/eval): Handle invoking binary with a directoryGriffin Smith1-9/+7
Similar to what we do for import, push on a `default.nix` to the path that the top-level is invoked with (if any) if it's a directory.

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`.

If the directory in which REPL history is stored does not exist, gently try to create it, but do not raise an error if it doesn't work. We may want to warn about it, but in general this sort of non-essential feature should not cause a hard failure.

2022-08-25 r/4488 feat(tvix/eval): Expose interpret + related types from libGriffin Smith1-12/+1
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.
