I'm using the pry REPL for ruby, and its rails plugin (the gem pry-rails). Currently pry has a global history for all projects. Is it possible to configure it such that each rails project will have its own history file?
There are instructions for this on the Pry wiki under history, here's the relevant part for what you want:
Example: Put the history file in the current directory, for a separate history per-project:
Permanently (in a .pryrc file)
Pry.config.history.file = ".pry_history"
