pip-dev

An interactive tool for testing Python version specifiers.

Description

​pip-dev is an interactive tool for testing Python version specifiers as defined by PEP 440. It allows developers to input constraints like >=1.4.5 or ~=1.4.5 and see which versions match, aiding in dependency management. Built on the pypa/packaging library, it helps ensure compatibility across Python projects.

Examples

Do you know the difference between >=1.4.5, ~=1.4.5 and ==1.4.*?

• nok.github.io/pip-dev?spec=>=1.4.5&vers=1.4.5
• nok.github.io/pip-dev?spec=~=1.4.5&vers=1.4.5
• nok.github.io/pip-dev?spec===1.4.*&vers=1.4.5

Do you know the difference between ~=1.4.5 and >=1.4.5,==1.4.*?

• nok.github.io/pip-dev?spec=~=1.4.5&vers=1.4.5
• nok.github.io/pip-dev?spec=>=1.4.5,==1.4.*&vers=1.4.5

And what about ~=1.2b,<=1.3a,!=1.2?

• nok.github.io/pip-dev?spec=~=1.2b,<=1.3a,!=1.2&vers=1.2.1
