| (二)简单例子 | |
| --Hello.g4 | |
| grammar Hello; | |
| main: 'Hello ' name '!'; | |
| name: ANY+; | |
| ANY: .; | |
| --Hello.kt | |
| package antlrdemo | |
| import com.huawei.antr.* | |
| import org.antlr.v4.runtime.CommonTokenStream | |
| import org.antlr.v4.runtime.CharStreams | |
| fun main(args: Array<String>) { | |
| val text = "Hello world!" | |
| val source = CharStreams.fromString(text) | |
| val lexer = HelloLexer(source) | |
| val tokenStream = CommonTokenStream(lexer) | |
| val parser = HelloParser(tokenStream) | |
| val name = parser.main().name().text | |
| println(name) | |
| } | |

重点关注如何使用ParseTreeProperty
升级到版本4.9.2，同时只生成listner模式的代码，解决了listener模式下不进入exitXXX函数的问题；
