那么，如何使用ANTLR手动为C#生成Lexer和Parser?

推荐答案

无需与Visual Studio集成.

No need for integration with visual studio.

在此处下载jar文件: http://www.antlr. org/download/antlr-runtime-4.5.1.jar

Download the jar file here: http://www.antlr.org/download/antlr-runtime-4.5.1.jar

将其保存到C:\Test

将jar添加到您的类路径中:

Add the jar to your classpath:

使用系统属性"对话框>环境变量>创建或附加到CLASSPATH变量

Using System Properties dialog > Environment variables > Create or append to CLASSPATH variable

在变量中，放入C:\Test\antlr-runtime-4.5.1.jar如果该变量的值已经存在，则在新条目之前插入;.

In the variable, put C:\Test\antlr-runtime-4.5.1.jar If values already exist for this variable, insert a ; before your new entry

将语法文件复制到C:\ Test

Copy in your grammar file to C:\Test

转到命令行，导航至C:\ Test

Go to the command line, navigate to C:\Test

创建"outputdirectory"文件夹，然后运行此文件夹(请记住要替换{outputdirectory}和{input}:

Create your 'outputdirectory' folder, and run this (remember to replace {outputdirectory} and {input}:

java org.antlr.v4.Tool -o -visitor -no-listener -Werror -o {outputdirectory} -Dlanguage=CSharp {input}.g4
