mise(-en-place)
I’m developing in ruby and for web, so also using node. I’ve been managing the versions of these tools with rbenv and nvm respectively, however, a better solution exists today. I kinda ignored asdf but today I can announce I’m fully a convert to mise. It will pick up on the existing .ruby-version and .nvmrc data if configured, and simply running mise install will get everything installed for your project. It is pretty fast as well (especiall nvm was sloooow).
