long lines in install_requires

[Gaasmann]

Hello,

I have a dependency for my package with a lot of extras (like apackage[extra1, extra2, extra3, extra4, ...]).
I'm not sure if I can split that into several lines in setup.cfg. I tried the following and some variations of it but I can't find something that works.

[options]
install_requires = 
    package1
    package2
    package3[
        extra1, extra2, extra3, extra4,
        extra5, extra6, extra7, extra8
    ]

pip tells me the following when I try to install:

pkg_resources.extern.packaging.requirements.InvalidRequirement: Parse error at "']'": Expected string_end

Is there a way to split my bunch of extras on several lines?

Thanks

Nicolas

Hi @Gaasmann , I don't think this is possible using setup.cfg. The .ini syntax is very limited...

Maybe you can try pyproject.toml and a some multiline TOML strings (I never tried myself, not sure if it works).

Hi @abravalheri, I'll try with the pyproject.toml. That said, this seems to be experimental. Do you see any risk to production applications? Issues with repackaging/installing aren't a big deal in my case.
Thanks!

The most experimental part in pyproject.toml is the [tool.setuptools] table and its subtables.
Since the [project] table is specified in PEP 621, if your project just needs this table to operate, it should be OK.

Ah ok, cool then. Thanks a lot!
