Implement "upgrade interactive" command

[djmattyg007]

Yarn (the Javascript package management tool) has an "upgrade interactive" command. It presets all updates available for all packages in package.lock, and for each package lets you choose whether you want to go to the very latest version (even if it's a new major version), to just the latest minor/patch version, or no change at all.

I think it would be great to see such a feature for poetry too. It would help to resolve certain version conflicts that just using up --latest can't deal with.

For example, at the time of writing, flake8-eradicate v1.4.0 has a dependency restriction of ">=3.5,<6" on flake8. Using up --latest fails when both of these packages are installed, because it's unresolvable. The latest version of flake8 is 6.x, and that's not compatible with the latest version of flake8-eradicate, so the dependency resolver doesn't know what to do and gives up.

If I could choose which updates I want for each package, I could deal with this problem directly. At the moment, the only solution I have is to manually update some dependencies and not use up --latest.

Hey @djmattyg007, thanks for reporting an issue.

I think an "upgrade interactive" command could be a great addition. However, I don't feel I have the time right now to implement this feature because I'm currently involved in other projects but feel free to contribute if you would like :)

Regarding your unresolvable issue, you can come around it by either pinning the package(s) that causes this issue or alternatively put them in a separate group and then exclude the group with up --latest --without my-group.
