Debug output

There is not output, the error window just pops up after 5 seconds. Your launch.json may looks like:

      "showDebugOutput": true,
      "trace": true,

      "program": "${file}"
    }
  ]
}

Details

Debugger doesn't run:

I am pretty sure it is an issue with the timeout not being long enough (my bash shell takes about 5 seconds to start up):

1. If I disable my init scripts, the debugger comes up.
2. If I instrument my init scripts to produce a heartbeat into a file, I can tail -f this heartbeat. When I start the debugger, the heartbeat shows that we go through the full initialization. But before we reach the end, the error message pops up.
3. I simplified the .bashrc to a sleep command. 4 seconds and below consistently gets the debugger to work; 5 seconds and above fails, and the error dialog comes up after exactly 5 seconds.

Note: Python used to have the same problem. They resolved it by making the timeout configurable in the launch.json configuration.

[dseynhae]

For the script I'm debugging right now, I can just disable my initialization. In my .bashrc, I return immediately if the Bash shell is invoked by the VS Code debugging environment:

# Don't run initialization when running in VS Code Debugger
if env | grep -q VSCODE_HANDLES; then
        return 1
fi

I would prefer to be able to increase the "timeout" in my launch.json configuration though...
