How to add dependencies?

[ubaldot]

I am newbie to Python and in my project I have added dependencies "by sight" in its pyproject.toml file that now has the following entries

[project]
dependencies = [
"numpy",
"scipy",
"pandas",
"matplotlib",
"control",
"typing",
"pathlib",
"tomli"
]

# For developers
[project.optional-dependencies]

build = ["hatch"]
test = [
  "pytest",
  "flake8",
  "mypy",
  "coverage"
]
docs = [
  "sphinx",
  "furo",
  "sphinx-toolbox",
  "sphinx-autodoc-typehints"
]

Nevertheless, I feel a bit uncomfortable by having added such dependencies by hand.

To make things clean, I decided to remove the above from my pyproject.toml file, create a new environment, and then run pytest/mypy/flake8/sphinx/etc and then every time I got a missing package error I run something like hatch add <missing package> but I don't know if such hatch add command exist.

Moreover, I would like to be able to differentiate the dev packages and "ordinary" packages.

For example, I wish a command hatch add such that:

1. If I run hatch add onepackage, then a line related to onepackage is added to pyproject.toml , e.g.

[tool.hatch.dependencies]
request = [
   "some_other_package",
   "onepackage"
]

2. If I run hatch add coolpackage "foo", then a line is added in e.g. the following way in the pyproject.toml

[tool.hatch.extra-dependencies]
foo = [
   "a_great_package",
   "coolpackage"
]

These are just examples, but I guess you get the point.

Would that be possible?

NOTE:
I wish hatch add only to add a line to pyproject.toml. I DON'T want hatch to also install the package, that I will do with conda install <package_name>. Unless when I run hatch add then it will automatically install it using conda.

In addition, I would be happy with something that allows me to add the path of a requirements.txt file. Something similar to the License field. If this is not a bad practice, of course.
