# Allows you to change code and see what the rust compiler does immediately in the opposite pane
|
|
|
|
# Instructions:
|
|
# - ./rustle.sh
|
|
# - select a rustling, see the split pane view show up
|
|
# - update until you have the solution, or you get sick of being stuck..
|
|
# - kill the tmux session (Prefix : kill-session)
|
|
# - do it all over again
|
|
|
|
# Built-in niceties:
|
|
# - checks you have everything, gives you hints where to get it
|
|
# - runs either the 'cargo run' or 'cargo test' based on if the code contains test code or not (naive)
|
|
# - override default editor with the EDITOR variable iow:
|
|
# EDITOR="emacs-or-vim -some-switches" ./rustle.sh
|
|
# - Should work on anything that has a recent bash (4.3.38 >=)
