[SOLVED] asdf-vm: Can I use global packages associated with the latest installed version of a runtime when working on a project that uses an older runtime?

asdf-vm: Can I use global packages associated with the latest installed version of a runtime when working on a project that uses an older runtime?

I will try to explain my question with an example. The contents of my ~./default-gems are:

gem-ctags
dip
bundler
gem-browse
pry
pry-byebug
pry-doc
pry-theme
rubocop
rubocop-performance
rubocop-rake
rubygems-update
ruby-debug-ide
ruby_parser
seeing_is_believing
solargraph
sqlint

This setup is working fine for me but I was wondering if there is a way to use the gems associated with my latest runtime (currently ruby 3.2.0-dev) when working with older runtimes and/or if it would pose compatibility issues.

If not for all global gems, at least for some of them, would it be safe to uninstall those associated with older runtimes?

Thank you

Solution

It seems that it is safe to remove global packages associated with older runtimes as long as I keep those installed with the lastest runtime. Then I can configure a project as usual, remembering to add the latest runtime at the end.

asdf local <plugin> <project version> <latest installed version> creates a .tool-versions file declaring that. For example, for a Ruby project I am testing, the .tool-versions contents are:

ruby 2.6.6 3.2.0-dev
