Example Scripts

Language Feature Scripts

There are also a number of examples scripts that showcase Rhai’s features, all in the scripts directory:

Script	Description
`array.rhai`	arrays example
`assignment.rhai`	variable declarations
`comments.rhai`	just regular comments
`doc-comments.rhai`	doc-comments example
`for1.rhai`	`for` loops
`for2.rhai`	`for` loops with array iterations
`for3.rhai`	`for` loops with closures
`function_decl1.rhai`	a function without parameters
`function_decl2.rhai`	a function with two parameters
`function_decl3.rhai`	a function with many parameters
`function_decl4.rhai`	a function acting as a method
`function_decl5.rhai`	multiple functions as methods for different data types
`if1.rhai`	`if` example
`if2.rhai`	`if`-expression example
`loop.rhai`	count-down `loop` in Rhai, emulating a `do` … `while` loop
`module.rhai`	import a script file as a module
`oop.rhai`	simulate object-oriented programming (OOP) with closures
`op1.rhai`	just simple addition
`op2.rhai`	simple addition and multiplication
`op3.rhai`	change evaluation order with parenthesis
`string.rhai`	string operations, including interpolation
`strings_map.rhai`	string and object map operations
`switch.rhai`	`switch` example
`while.rhai`	`while` loop

The following scripts are for benchmarking the speed of Rhai:

Scripts	Description
`speed_test.rhai`	a simple application to measure the speed of Rhai’s interpreter (1 million iterations)
`primes.rhai`	use Sieve of Eratosthenes to find all primes smaller than a limit
`fibonacci.rhai`	calculate the n-th Fibonacci number using a really dumb algorithm
`mat_mul.rhai`	matrix multiplication test to measure the speed of multi-dimensional array access

The rhai-run utility can be used to run Rhai scripts:

cargo run --bin rhai-run scripts/any_script.rhai
