Issue

Hi,

I'm looking to move Colour to Poetry, so far so good except for a minor issue on Github Actions and Windows.

There is however something I might be overlooking but I did not find a good answer for. The context is that issuing pip install 'colour-science[development]' will install our development dependencies.

I obviously don't want to lose that capability and the only solution I found is rather unelegant: I need to have our development dependencies listed two times (well, three to be exact):

• In the [tool.poetry.dependencies] section where they are marked as optional, then they can be used in the [tool.poetry.extras] section to populate accordingly the setup.py file generated with the poetry build command.
• In [tool.poetry.dev-dependencies] so that poetry install installs everything we need for development.

Here is my current pyproject.toml file for reference:

[tool.poetry]

Please let me know if I missed something or if it is a current limitation.

You only have to specify them once in the tool.poetry.dependencies section as optional and add the development extra to tool.poetry.extras. No need to specify them in tool.poetry.dev-dependencies. Then you need to do poetry install --extras development

Hi Seb,

Sure, but then poetry install does not install my development dependencies:

I've just run into the same thing, except I'm looking to have a [docs] extra, which ideally is installed normally as a dev dep in the general case, but is able to be included in the extras.

Could extras pull from both dependencies and dev-dependencies. Wherein, they're not included by default during a poetry install if they're in dependencies (a-la current behavior), but are included by default when they're dev-dependencies?

[kelvin-tran]

Seems that the solution is referenced here: #3180

Eg:

[tool.poetry.dev-dependencies]

moto = { extras=["s3", "sns", "sqs", "awslambda", "xray"], version = "^2.0.1" }
