Functions ¶

func Compile ¶

func Compile(node ast.Node, options ...Option) (*object.Code, error)

Compile the given AST node and return the compiled code object. This is a shorthand for compiler.New(options).Compile(node).

func MakeInstruction ¶

func MakeInstruction(opcode op.Code, operands ...uint16) []op.Code

Types ¶

type Compiler ¶

type Compiler struct {
	// contains filtered or unexported fields
}

Compiler is used to compile Risor AST into its corresponding bytecode. This implements the ICompiler interface.

func New ¶

func New(options ...Option) (*Compiler, error)

New creates and returns a new Compiler. Any supplied options are used to configure the compilation process.

func (*Compiler) Compile ¶

func (c *Compiler) Compile(node ast.Node) (*object.Code, error)

Compile the given AST node and return the compiled code object.

func (*Compiler) CurrentInstructions ¶

func (c *Compiler) CurrentInstructions() []op.Code

CurrentInstructions returns the compiled instructions for the code that is currently being compiled. This may be the main code object, or it may be a function that is being compiled.

func (*Compiler) MainInstructions ¶

func (c *Compiler) MainInstructions() []op.Code

MainInstructions returns the compiled instructions for the main code object.

type Option ¶

type Option func(*Compiler)

Option is a configuration function for a Compiler.

func WithBuiltins ¶

func WithBuiltins(builtins map[string]object.Object) Option

WithBuiltins configures the compiler with the given built-in objects.

func WithCode ¶

func WithCode(code *object.Code) Option

WithCode configures the compiler to compile into the given code object.
