I’m working on a project where I need to install all of the Poetry extras to run an automated build. What is the easiest way to get that list as a space-separated list, for use in poetry install --extras="$extras"?
Some possibilities:
- I could use the Python toml package, but that would require setting up a separate virtualenv to install it.
- A quick
sedcommand to get thetool.poetry.extrassection of pyproject.toml and pull out the names would be a hack, and only works if the TOML is nicely and consistently formatted. - Downloading and installing a third party CLI tool just for this seems overkill; I’d prefer a
sedhack over that. - Maybe there’s a commonly installed tool (as in, already installed in the official Ubuntu 20.04 Docker image) which can do this or something adjacent like converting TOML to JSON for processing with a more well-known tool like
jq, but I’m not aware of it.

Sorry, cannot add as a comment, but probably you could use now
poetry install --all-extras
with newer Poetry version https://python-poetry.org/docs/pyproject/#extras
