where is the install .[dev] format/syntax defined ? I was trying to find what was possible and how to make sense of it in setup.cfg tools I found one mention in the docs but no more.

It’s a pip-ism; as far as I know, it’s not defined in any PEP. It should be in their documentation, however.

  gonna dig deeper there then, thanks

you may have done pip install jupyter[notebook] this is the same thing, just for . (current directory) and dev variant.
- woodruffw 4y ago
  Yep. The key difference is that the former is specified in PEP 508, while `.` and its variants are a convenience feature that pip (and maybe some other tools) provide.

  yeah but I'm missing data on how variant interacts with various requirements defined in setup.cfg (testing dependencies for instance)

PEP-508[0] explains the grammar for "extras": > Optional components of a distribution may be specified using the extras field: identifier_end = letterOrDigit | (('-' | '_' | '.' )* letterOrDigit) identifier = letterOrDigit identifier_end* name = identifier extras_list = identifier (wsp* ',' wsp* identifier)* extras = '[' wsp* extras_list? wsp* ']' as well as explaining their behavior, albeit briefly: > Extras union in the dependencies they define with the dependencies of the distribution they are attached to. The resolution on . is explained by the pip documentation[1]: > pip looks for packages in a number of places: on PyPI (if not disabled via --no-index), in the local filesystem, and in any additional repositories specified via --find-links or --index-url. There is no ordering in the locations that are searched. Rather they are all checked, and the “best” match for the requirements (in terms of version number - see PEP 440 for details) is selected.
