2024-04-04 r/7851 feat(tvix/eval): implement `appendContext`Ryan Lahfa1-1/+1
`appendContext s ctx` will just append a user-crafted context attrs to `s`. The most important part of this builtin is to perform all the relevant invariant validations to avoid letting the user craft invalid contexts which can never be built, e.g. invalid store paths, inexistent derivations, etc. This version is incomplete and full of TODOs, but passes all the Nix's context strings tests, so we turn them on.

2024-03-31 r/7806 feat(tvix/eval): implement `unsafeDiscardOutputDependency`Ryan Lahfa1-1/+1
This builtin only transforms any `NixContextElement::Derivation` into the trivial `NixContextElement::Plain`. This is a forgetful functor on derivation-deep context strings. The test coverage of this change is done in cl/11264.

2024-02-29 r/7625 feat(tvix/eval): implement `builtins.hashFile`Padraic-O-Mhuiris1-1/+1
The primary addition is the `builtin_hashFile` function which attempts value-path coercion and on success reads the file to a nix_string. Similar to the `builtins_hashString` implementation, the hash is then derived using the `hash_nix_string` function in the introduced hash module which has extracted hashing functionality initially specified in cl/11005.

We're getting close to the finish line, folks. I went through the list of builtins and there are only 33 that remain unimplemented. I've marked them, and indicated which are ready to be implemented vs which are waiting for other things. We can delete this column from the table once everything is implemented.

2022-09-04 r/4647 docs(tvix/eval): add a list of builtins added in Nix >= 2.4sterni1-0/+11
`builtins.getFlake` doesn't interest us, of course, but some others may be worth (or easy) to implement. They are pretty low priority, though, since nixpkgs has compatiblity wrappers for the ones it uses. The new debugging-related builtins (break and traceVerbose) are interesting to note, but may not make sense to implement at all.
