How does one pip install with all extras? I'm aware that doing something like:

pip install -e .[docs,tests,others]

is an option. But, is it possible to do something like:

pip install -e .[all]

This question is similar to setup.py/setup.cfg install all extras. However, the answer there requires that the setup.cfg file be edited. Is it possible to do it without modifying setup.py or setup.cfg?

No until the author of the package declares all extras in setup.py. Something like

docs = […]
tests = […]
others = […]
all = docs + tests + others

setup(
    …,
    extras_require = {
        'all': all,
        'docs': docs,
        'tests': tests,
        'others': others,
    },
    …,
)

I do it this way:

import itertools

extras_require = {
   'foo': [],
   'bar': [],
}
extras_require['all'] = list(itertools.chain.from_iterable(extras_require.values()))
