fn (mut p Parser) codegen(code string)

codegen allows you to generate V code, so that it can be parsed, checked, markused, cgen-ed etc further, just like user's V code.

fn (mut p Parser) compile_template_file(template_file string, fn_name string) string

compile_file compiles the content of a file by the given path as a template

fn (mut p Parser) free()

fn (mut p Parser) parse() &ast.File
