2023-12-01Put functional tests in `tests/functional`John Ericson
I think it is bad for these reasons when `tests/` contains a mix of functional and integration tests - Concepts is harder to understand, the documentation makes a good unit vs functional vs integration distinction, but when the integration tests are just two subdirs within `tests/` this is not clear. - Source filtering in the `flake.nix` is more complex. We need to filter out some of the dirs from `tests/`, rather than simply pick the dirs we want and take all of them. This is a good sign the structure of what we are trying to do is not matching the structure of the files. With this change we have a clean: ```shell-session $ git show 'HEAD:tests' tree HEAD:tests functional/ installer/ nixos/ ``` (cherry picked from commit 68c81c737571794f7246db53fb4774e94fcf4b7e)
2013-12-31Add the ExprBuiltin Expr type to the ASTShea Levy
Certain desugaring schemes may require the parser to use some builtin function to do some of the work (e.g. currently `throw` is used to lazily cause an error if a `<>`-style path is not in the search path) Unfortunately, these names are not reserved keywords, so an expression that uses such a syntactic sugar will not see the expected behavior (see tests/lang/eval-okay-redefine-builtin.nix for an example). This adds the ExprBuiltin AST type, which when evaluated uses the value from the rootmost variable scope (which of course is initialized internally and can't shadow any of the builtins).
