Dependency was renamed, how should I allow both names

[Neyri]

Hello,

I am using poetry to manage the dependencies of my package in a pyproject.toml. Recently one of my dependencies was renamed (fuzzywuzzy became thefuzz) and I want my users to be able to use either one of them. More precisely, I would like to be able to specify the following behaviour :

• if either of these packages is already installed, use it
• otherwise, install the package with the latest version (fuzzywuzzy stops at 0.18 and thefuzz is already at 0.19)

How can I set the pyproject.toml to match this behaviour ?

I do not think python packaging metadata today allows for this behavior, ie. "install one of". You can potentially achieve this behaviour by adding both fuzzywuzzy and thfuzz as optional dependencies associated with separate extras. However, this is only really useful if both packages are going to be maintained going forward and your users get to decide what package they want to use.

However, the better approach might be update your project's dependency to the new package. So any existing installations will use the old package, but will not upgrade the dependency beyond 0.18. And any consumers of your package's new version will simply use the package.
