I'm attempting to enhance a simple grammar to support entries longer than one line. The Eclipse project with all the code is http://tinyurl.com/yj62hqe Using ANTLR and Eclipse was easy thanks to the excellent JavaDude screencasts[0].
Quiz.java correctly identifies the question (q), correct answer (c), and incorrect answer (i) for single line entries. q : 1. hi c : *a. hi i : b. bye q : 1. bye i : a. hi c : *b. bye The quiz language is similar to grammars found in jbehave[1] and Gherkin[2][3]. In these grammars there are no explicit end keywords. I also looked at the wiki example from tpdsl[4], however that fails on the most basic wiki input such as * 1 * 2 MQuiz.g contains my failed attempt at using ideas from the Gherkin Ragel[5] grammar to support multiple lines. Does anyone know how to support multiline properly in this grammar with ANTLR? Thanks.
