mu/sandbox/Readme.md

Variant of the Mu programming environment that runs just the sandbox.

Suitable for people who want to run their favorite terminal-based editor with Mu. Just run editor and sandbox inside split panes atop tmux. For example, here's Mu running alongside vim:

To set this up:

a) copy the lines in tmux.conf into $HOME/.tmux.conf.

b) copy the file mu_run somewhere in your $PATH.

Now when you start tmux, split it into two vertical panes, run ./mu sandbox on the right pane and your editor on the left. You should be able to hit F4 in either side to run the sandbox.

Known issues: you have to explicitly save inside your editor before hitting F4, unlike with ./mu edit.
