Live demo on repl.it

[arxanas]

https://repl.it lets you launch a REPL (for free). It supports Rust as a programming language and Linux as the environment.

It uses Nix somehow and has integrations to launch a Github repository in repl.it. So it should be possible to set it up so that it installs the git-branchless Nix package. After a small amount of fiddling, I was able to install git-branchless from Nix and set up a local Git repository, so that I could run git sl.

@nh2: have you ever done anything like this, and would you be able to help out? In particular:

• Is it sensible to do set up like configure the user's Git credentials or make a commit as part of the replit.nix file (documented here: https://docs.replit.com/programming-ide/getting-started-nix)? Or does that belong somewhere else?
• What are the steps to upgrade and test a new version of git-branchless in Nix? What kind of turnaround time can I expect from the maintainers of the Nix repositories?
