* doc: auto-generate asserts and attrset library docs•••If all the docs are auto-generated, it should be easier to convert them to Commonmark. Co-Authored-By: Valentin Gagarin <valentin.gagarin@tweag.io> Co-Authored-By: Silvan Mosberger <contact@infinisil.com> Ryan Mulligan2022-12-081-4/+15
* lib/asserts: use throw to display message for assertMsg•••`assert` has the annoying property that it dumps a lot of code at the user without the built in capability to display a nicer message. We have worked around this using `assertMsg` which would *additionally* display a nice message. We can do even better: By using `throw` we can make evaluation fail before assert draws its conclusions and prevent it from displaying the code making up the assert condition, so we get the nicer message of `throw` and the syntactical convenience of `assert`. Before: nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; } trace: Deterministic builds require stripping bytecode. error: assertion (((lib).assertMsg (reproducibleBuild -> stripBytecode)) "Deterministic builds require stripping bytecode.") failed at /home/lukas/src/nix/nixpkgs/pkgs/development/interpreters/python/cpython/2.7/default.nix:45:1 After: nix-repl> python.override { reproducibleBuild = true; stripBytecode = false; } error: Deterministic builds require stripping bytecode. sternenseemann2022-01-191-12/+10
* lib: move assertMsg and assertOneOf to their own library file•••Since the `assertOneOf` uses `lib.generators`, they are not really trivial anymore and should go into their own library file. Profpatsch2018-09-061-0/+44
