py3dephell 0.2.1

Helps to control project dependencies and provides

Py3DepHell

This project presents tools to work with dependencies and provides of python3 projects.

py3req

This module detects dependencies of python3 packages. It has verbose --help option, but here is simple example how to use it:

py3prov

This module generate provides for python3 packages. As for py3req its --help is verbose enough

How to

Imagine you have simple project like this one:

src/
├── pkg1
│   ├── mod1.py
│   └── subpkg
│       └── mod3.py
└── tests
    └── test1.py

Now you want to detect its dependencies:

% python3 -m py3dephell.py3req --pip_format src
unittest
re
re

Feel free to make it more verbose:

% python3 -m py3dephell.py3req --pip_format --verbose src
py3prov: detected potential module:src
/tmp/.private/kotopesutility/src/tests/test1.py:unittest
/tmp/.private/kotopesutility/src/pkg1/mod1.py:requests os
/tmp/.private/kotopesutility/src/pkg1/subpkg/mod3.py:re

As you can see, there are some modules from standard library, so let py3req to learn it:

% python3 -m py3dephell.py3req --pip_format --add_prov_path /usr/lib64/python3.11 src
requests

That's it! But what if we want to detect its provides, to understand which dependencies it could satisfy? Let's use py3prov!

% python3 -m py3dephell.py3prov src
test1
tests.test1
src.tests.test1
mod1
pkg1.mod1
src.pkg1.mod1
mod3
subpkg.mod3
pkg1.subpkg.mod3
src.pkg1.subpkg.mod3

Yeah, let's enhance the verbosity level!

% python3 -m py3dephell.py3prov --verbose src/pkg1 src/tests
src/tests:['test1', 'tests.test1', 'src.tests.test1']
src/pkg1:['mod1', 'pkg1.mod1', 'src.pkg1.mod1', 'mod3', 'subpkg.mod3', 'pkg1.subpkg.mod3', 'src.pkg1.subpkg.mod3']
