I used parinfer for a 1-2 months. Then I quit and switched back. Wayyyy too many silent errors that get introduced and you don't notice them until runtime. Especially if you edit code that other people wrote.
I've also seen at least 4 people in the chats/forums that had errors because of parinfer. So no, I won't recommend it to a beginner.
Ok, that's a fair point. If you open code indented somewhere else, there might be changes.
In my experience, as my IDE (Intellij Idea) highlights lines that are changes for git, these errors are trivially detected. But perhaps for a newbie, this could be confusing? In any case I still think it is a net win.
