Using watchfiles to run two commands with "&&"

[hugovk]

I'd like to use watchfiles for Advent of Code.

When run with pytest, the Python runs unit tests on the short example. And when run with the Python interpreter, runs against the full input.

For example, I run:

pytest part1.py && python3 part1.py

• When the unit tests aren't working yet, only the quick unit tests run with pytest.
• Then when the tests pass, it next runs the interpreter on the full, slow input.

I'd like to do something like:

watchfiles "pytest part1.py && python3 part1.py"

But it passes the whole thing to pytest which errors with "ERROR: file or directory not found: &&"

A workaround is to put pytest part1.py && python3 part1.py in a bash file and run:

watchfiles thing.sh

And I could create an alias, but would it be possible or sensible for watchfiles to handle it?

happy to accept a PR to support this, either special casing && or somehow running this with bash etc.
