List outdated packages using poetry

Problem

I use poetry as my python package manager and I'd like to know the packages that I depend on that are currently outdated.

Solution

An easy way to get this list is to run poetry show --outdated. This will return you a list of all the packages that are outdated, their current version, the latest version, as well as a description of the package.

There are in my opinion three missing features here:

• having the command respect the semantic versioning constraint and only letting you see the latest version according to those constraints
• having a flag to switch between showing the latest version available without semantic versioning constraint vs the latest version constrained by semantic versioning
• having a flag to list only the packages that are direct dependencies (listed in the pyproject.toml file)
