Implementations

impl Interpreter

pub fn new() -> Self

Creates a new interpreter.

pub fn interpret( self, program: Program<'_>, argc: usize, argv: Vec<String>, ) -> OYResult<u8>

Interprets the given program. This will return the exit code of the program.

pub fn execute_function( &mut self, function: FunctionStatement, args: Vec<Arg>, ) -> OYResult<ObjectExpression>

Executes the given function with the given arguments. This will return the result of the function. If the function does not return anything, it will return nil.

Note: The environment should contain a fream for the function (Will removed after the function is executed)

pub fn execute_statement( &mut self, statement: Statement, ) -> OYResult<Option<ObjectExpression>>

Executes the given statement. This will return the result of the value of return statement. if there is no return statement, it will return nil.

pub fn execute_assign(&mut self, assign: AssignmentStatement) -> OYResult<()>

Executes the given assign statement. This will execute the expr and save the varibal with the object

pub fn execute_expression( &mut self, expr: ExpressionStatement, ) -> OYResult<ObjectExpression>

Executes the given expression. This will return the result of the expression.

pub fn execute_function_call( &mut self, func_call: FunctionCallExpression, ) -> OYResult<ObjectExpression>

Executes the given function call. This will return the result of the function call.

pub fn execute_value( &mut self, value: ValueExpression, ) -> OYResult<ObjectExpression>

Executes the given value. This will return the result of the value.
