Using the interpreter
After successfully installing the interpreter you will have the
roo binary at your disposal. For clarity, in the following examples the
$ denotes the command line prompt.
Running a script
Running a script is easy. Just pass as an argument to the Roo interpreter the full path to the script to run:
$ roo my_program.roo
Using the REPL
It’s possible to use the interpreter as a REPL. This allows the execution of Roo commands with immediate response in real-time.
$ roo Roo interpreter (v2.5.0) >>>
Jyst type Roo commands at the prompt (
>>>) and you’ll get immediate output from the Terminal.
You can get basic help from the interpreter with the
$ roo -h Roo interpreter (v2.5.0) Usage: roo [option] roo <file> : Run a script roo -h : Display help roo -v : Display the interpreter's version number
You can see the current version of the Roo interpreter installed on your system with the
$ roo -v 2.5.0
