Can't get debugger to work

[MishaBeek]

Hi,

I know a similar issue has been posted, but that does not seem to cause of my problem.
I have set up the following launch file:

{ "version": "2.0.0", "configurations": [ { "name": "Debug ANTLR4 grammar", "type": "antlr-debug", "request": "launch", "input": "MyParser/example1.sql", "grammar": "MyParser/src/main/java/org/parser/MyParser.g4", "startRule": "statement", "printParseTree": true, "visualParseTree": true } ] }

When starting the debug with F5 I get an error message: 'typeerror cannot set property 'inputstream' of undefined'

Both the grammar file (combined) and the input file exist. The startRule also exists in the grammar. I just trying to locate the cause of this issue. I am using VsCode on Windows 10.

Any advice/guidance is appreciated.

Thanks,

Misha

Have you enabled parser generation and saved your grammar at least once?

I think I did (how can I double check). In the mean time I am separating the Lexer from the Parser, which does allow me to run the debugger. This generates a lot of other issues, but these are unrelated.

The default for parser generation is internal which saves all the generated file (and most important: the interpreter data) in the subfolder .antlr of your workspace folder. See there if you have the . interp file for your grammar. Debugging is not possible without this file. And btw, it doesn't make any difference if you use a combined or separated grammar.

Anything I can do here yet? If not I'll close the issue.
