Function ParseFile

parser/parser.go:165–182

ParseFile parses the source code of a single JavaScript/ECMAScript source file and returns the corresponding ast.Program node. If fileSet == nil, ParseFile parses source without a FileSet. If fileSet != nil, ParseFile first adds filename and src to fileSet. The filename argument is optional and is

(fileSet *file.FileSet, filename string, src interface{}, mode Mode, options ...Option)

//	// Parse some JavaScript, yielding a *ast.Program and/or an ErrorList
//	program, err := parser.ParseFile(nil, "", `if (abc > 1) {}`, 0)
func ParseFile(fileSet *file.FileSet, filename string, src interface{}, mode Mode, options ...Option) (*ast.Program, error) {
	str, err := ReadSource(filename, src)
	if err != nil {
		return nil, err
	}
	{
		str := string(str)

		base := 1
		if fileSet != nil {
			base = fileSet.AddFile(filename, str)
		}

		parser := _newParser(filename, str, base, options...)
		parser.mode = mode
		return parser.parse()
	}
}

// ParseFunction parses a given parameter list and body as a function and returns the
// corresponding ast.FunctionLiteral node.
