Cannot find tokens file #1351

Closed jannavarro closed 4 years ago

jannavarro commented 5 years ago

I am following this ANTLR4 tutorial for C# and in step 4 I run the ANTLR java file in the C# grammar file I downloaded in your Github (grammars-v4/csharp/). java -jar antlr4-4.7.2.jar -Dlanguage=CSharp CSharpParser.g4

The result is an error looking for tokens file: error(114): CSharpParser.g4:7:21: cannot find tokens file .\CSharpLexer.tokens

I am quite new to Antlr. Is this token file something I can get somewhere else?

Firstly you should generate tokens file by command java -jar antlr4-4.7.2.jar -Dlanguage=CSharp CSharpLexer.g4
