[BUG?] ANTLR4 IDE ignores -visitor, -no-listener settings

[xoxota99]

Using ANTLR4 SDK 0.3.5 w ANTLR Tool v4.4
Setting options (via Project > Properties > ANTLR4 > Tool > Options) for -listener or -visitor appears to be ignored, or at best sometimes will not generate a listener. There doesn't seem to be a way to generate a Visitor.

Hi xoxota99,

In fact I had the same problem once, I used to integrate two G4 files in the same project the first one generated Visitor but the second didn't.

Then I realized that each G4 file has its own configuration for code generation that you can change by:

• Right click on the G4 file then "Run As"
• Choose "External tool configuration"
• Change the -no-visitor to -visitor, you can do the same for listener.

Now the Visitor file is generated.

I'm trying to clean up the issues page. If there is nothing outstanding, let me know so I can close this. Otherwise I will close as invalid in two weeks.

I ran into the same issue on version 0.3.6.201611052310.
The solution provided by @atefthab works fine. Why is this not resolved already? Seems like an easy fix to accept the project Antlr options and use those instead. Thanks!

@anchakarov can you check if you have an external runtime config for the g4 file ?
