Functions ¶

func Parse ¶

func Parse(builder shared.NodeBuilder, importReporter packageloader.ImportHandler, source compilercommon.InputSource, input string) (shared.AstNode, bool)

Parse performs parsing of the given input string and returns the root AST node.

func ParseExpression ¶

func ParseExpression(builder shared.NodeBuilder, source compilercommon.InputSource, startIndex int, input string) (shared.AstNode, bool)

ParseExpression parses the given string as an expression.
