Debugging breakpoints are ignored

brikken commented 5 years ago

I've set a breakpoint in my grammar, but debugging (F5) doesn't stop execution at the breakpoint. It simply continues right to the end and produces the parse tree.

Grammar

grammar Test;

program: id*;
id: ID;

ID: [a-zA-Z]+;
WS: [ \t\r\n]+ -> skip;

launch.json

{
    "version": "2.0.0",
    "configurations": [
        {
            "type": "antlr-debug",
            "request": "launch",
            "name": "antlr4",
            "input": "input.txt",
            "grammar": "Test.g4",
            "startRule": "program",
            "printParseTree": true,
            "visualParseTree": true
        }
    ]
}

In addition, I have to specify the "grammar" and "startRule" elements for debugging to even work, even though the grammar file is active in the editor.

Same problem to me Any solution here?

There was a problem with breakpoint resolution, which I fixed recently. Can you guys try the latest version from the vscode marketplace and let me know if that solves your issues?

I still had the test from my original post lying around, so I tried it again. Now it breaks at the breakpoint, but both stepping over (F10) and stepping in (F11) finishes the debugging session and outputs the parse tree to the debug log. If that's a real issue, I'll create a new one.

@elipersonal Please don't hijack an already closed bug. Usually such bugs (particularly when they are so old) have completely different circumstances to consider, than your current problem. Instead, open a new bug. Thanks.
