The source code may be provided as a string, []byte, or io.Reader, and the mode parameter controls the amount of source code parsed and other optional parser functionality. 2. func ParseDir(fset *token.FileSet, path string, filter func(os.FileInfo) bool, mode Mode) (map[string]*ast.Package, error) ParseDir parses the package source files in the directory identified by path and returns the corresponding ast.Package nodes. The filter function determines which files to include in the package. The mode parameter controls the amount of source code parsed and other optional parser functionality. 3. func ParseExprFrom(fset *token.FileSet, filename string, src interface{}, mode Mode) (ast.Expr, error) ParseExprFrom parses the source code and returns the corresponding ast.Expr node. The source code may be provided as a string, []byte, or io.Reader, and the mode parameter controls the amount of source code parsed and other optional parser functionality. 4. func ParseExpr(src string) (ast.Expr, error) ParseExpr is a wrapper around ParseExprFrom that parses a single expression from a string. 5. func ParseFile(fset *token.FileSet, filename string, src interface{}, mode Mode) (*ast.File, error) ParseFile parses the source code in the file identified
