The following command first runs three scripts –
loading the functions defined in each script into the global namespace.
Then it enters an REPL, which can call the above functions freely.
rhai-repl init1.rhai init2.rhai init3.rhai
rhai-run to run Rhai scripts.
Filenames passed to it as command line arguments are run in sequence as Rhai scripts.
The following command runs the scripts
script3.rhai in order.
rhai-run script1.rhai script2.rhai script3.rhai
rhai-dbg to debug a Rhai script.
Filename passed to it will be loaded as a Rhai script for debugging.
The following command debugs the script
