2022-10-10	r/5086 feat(tvix/eval): Add a struct implementing NIX_PATH	Griffin Smith	1	-0/+1
	Add a simple struct implementing both the string parsing and path resolution rules of Nix's `NIX_PATH` environment variable, for use in resolving `<...>`-style paths Change-Id: Ife75f39aa5c12928278d81fe428fbadc98bac5cc Reviewed-on: https://cl.tvl.fyi/c/depot/+/6917 Autosubmit: grfn <grfn@gws.fyi> Reviewed-by: tazjin <tazjin@tvl.su> Reviewed-by: Adam Joseph <adam@westernsemico.com> Tested-by: BuildkiteCI
2022-10-08	r/5057 refactor(tvix/eval): move `spans` module to crate root	Vincent Ambo	1	-0/+1
	This is also useful for error-handling related logic, outside of just the compiler module. Change-Id: I5c386e2b4c31cda0a0209b31136ca07f00e39e45 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6869 Tested-by: BuildkiteCI Reviewed-by: grfn <grfn@gws.fyi>
2022-10-05	r/5035 refactor(tvix/eval): introduce source::SourceCode type	Vincent Ambo	1	-0/+2
	This type hides away the lower-level handling of most codemap data structures, especially to library consumers (see corresponding changes in tvixbolt). This will help with implement `import` by giving us central control over how the codemap works.

2022-09-18	r/4911 refactor(tvix/eval): use Clap for arg+env parsing	Griffin Smith	1	-1/+1
	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`.

	This is pretty boring at the moment, but mostly serves as a foot in the door in the direction of writing more tests Change-Id: Id88eb4ec7e53ebb2d5b5c254c8f45ff750238811 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6637 Autosubmit: grfn <grfn@gws.fyi> Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>
2022-09-17	r/4894 test(tvix/eval): Add proptests covering trait impls for String	Griffin Smith	1	-0/+2
	Add a suite of proptests covering the laws of the handwritten stdlib trait impls (Eq, Ord, and Hash) for String, generated from a new set of macros for generating those tests which can be applied to other types.

	These are required for tvixbolt to work. This interface is definitely not stable yet, though. Change-Id: I4076498e8f42311de74ee4f33c93a3ee0c5f8d3a Reviewed-on: https://cl.tvl.fyi/c/depot/+/6450 Reviewed-by: sterni <sternenseemann@systemli.org> Tested-by: BuildkiteCI
2022-09-09	r/4775 feat(tvix/eval): implement DisassemblingObserver for compiler	Vincent Ambo	1	-3/+1
	This type implements an observer that is called whenever the compiler emits a chunk (after the toplevel, thunks, or lambdas) and prints the output of the disassembler to its internal writer. This replaces half of the uses of the `disassembler` feature, which has been removed from the Cargo configuration. Note that at this commit runtime tracing is not yet implemented as an observer.

2022-09-09	r/4774 feat(tvix/eval): implement (compilation) observer trait	Vincent Ambo	1	-0/+1
	This trait will enable library users of tvix-eval to observe internal happenings of the compilation and runtime processes. The initial methods of the observer will be called whenever the compiler emits a chunk.

2022-09-06	r/4677 refactor(tvix/eval): introduce UpvalueCarrier trait	Vincent Ambo	1	-0/+1
	This trait abstracts over the commonalities of upvalue handling between closures and thunks. It allows the VM to simplify the code used for setting up upvalues, without duplicating between the two different types. Note that this does not yet refactor the VM code to optimally make use of this.

2022-09-02	r/4588 feat(tvix/eval): introduce mechanism for defining builtins	Vincent Ambo	1	-0/+1
	Adds a new builtins module in which builtins can be constructed. The functions in this module should return a correctly structured value to be passed to the compiler's `globals`. This is wired up all the way to the compiler with an example `toString` builtin, available as a global. Note that this does not yet actually behave like the real toString, which has some differences from `Display`.

2022-08-30	r/4533 feat(tvix/eval): implement optional runtime tracing	Vincent Ambo	1	-0/+3
	This adds a `disassembler` feature to the crate configuration that traces the operations executed and the state of the stack at runtime. This can be enabled by compiling with `--feature disassembler`. This will also gain a more sensible layout of code slices eventually.

2022-08-25	r/4488 feat(tvix/eval): Expose interpret + related types from lib	Griffin Smith	1	-0/+14
	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.
