parseTemplate function

Program parseTemplate(String source)

Parses the Jinja template source into a Program without rendering it.

Before parsing, \r\n and \r become \n and one trailing newline is removed. Positions in the result and in a thrown exception refer to that normalized text, which is also the exception's source.

Throws a LexerException if source cannot be tokenized, or a ParserException if its tokens do not form a valid template.

Implementation

Program parseTemplate(String source) {
  final lexed = Lexer(source).tokenize();
  return Parser(lexed.tokens, lexed.source).parse();
}
