Types

type Compiler

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

Compiler is a stateful compiler that can be used to gradually build an il.Program out of multiple independent compilation of expressions.

func New

func New(finder ast.AttributeDescriptorFinder, functions map[string]ast.FunctionMetadata) *Compiler

New returns a new compiler instance.

func (*Compiler) CompileExpression

func (c *Compiler) CompileExpression(text string) (uint32, descriptor.ValueType, error)

CompileExpression creates a new parameterless IL function, using the given expression text as its body. Upon success, it returns the id of the generated function.

func (*Compiler) Program

func (c *Compiler) Program() *il.Program

Program returns the program instance that is being built by this compiler.
