Useful decorators and context managers

Highlights

See the docs linked from the badge above for the full details, but here are some features that may be of interest.

• ExceptionTrap provides a general-purpose wrapper for trapping exceptions and then acting on the outcome. Includes passes and raises decorators to replace the result of a wrapped function by a boolean indicating the outcome of the exception trap. See this keyring commit for an example of it in production.

• suppress simply enables contextlib.suppress as a decorator.

• on_interrupt is a decorator used by CLI entry points to affect the handling of a KeyboardInterrupt. Inspired by Lucretiel/autocommand#18.

• pushd is similar to pytest’s monkeypatch.chdir or path’s default context, changes the current working directory for the duration of the context.

• tarball will download a tarball, extract it, change directory, yield, then clean up after. Convenient when working with web assets.

• null is there for those times when one code branch needs a context and the other doesn’t; this null context provides symmetry across those branches.
