Executing Code

In order to execute code in any language, simply hit on the run button in the top left hand corner of a pad. We also give a handy keyboard shortcut if you don’t want to take your hands off the keyboard:


command + enter OR CTRL + S


CTRL + enter OR CTRL + S

Program Output

The program output is located in the right-pane of the IDE. As soon as you click on the “Run” button, your code will be executed and showcase the program output. If there are any errors in the code that is executed, the errors will also show in the REPL.

To clear the output of the REPL at any time, simply click on the “Reset” button, located in the top right hand corner of a pad. Note, this will not reset any code in the left hand pane. It will simply clear the output within the REPL.

For some languages (Ruby, Python, Javascript) – the REPL carries over variables from the left pane, and are available in the REPL. For other languages (Clojure, Erlang, OCaml, Perl, R, MySQL, PostgreSQL) is “disconnected” from the left pane.

Any code written into the REPL isn’t saved/visible in playback.
