niddle is a nREPL middleware that prints eval-ed forms and their corresponding results onto stdout of the nREPL server process. One use-case for this middleware is when the nREPL server is started non-interactively on the cli, but you'd like to keep track of all that has been eval-ed on the same CLI. (think Cursive REPL)

Colored pretty printing is done with puget.

I really like the idea of having single REPL view that keeps track of all eval-ed forms and values, no matter where they came from. This supports a workflow where forms maybe sent from either CLI nREPL client, an editor, or even a running process.

I've tried looking for tooling that gives this experience on vim+tmux setup, but neither vim-fireplace nor vim-iced seem to provide that. In fact since the goal is to show all eval-ed forms from any client, the intercept point must be on the server-side, hence a nREPL middleware.
