Any way to support environment variables?

[fwcd]

The debug adapter currently does not support this. To support custom environment variables, we might have to start the debuggee process externally and connect the debug adapter to it through a socket. This is, at least, what the Java extension does: microsoft/java-debug#89

Edit: Note that you can already launch your process externally with the following JVM args:
-Xdebug -agentlib:jdwp=transport=dt_socket,address=$PORT,server=y,quiet=y,suspend=y
...then connect the debug adapter through VSCode to port $PORT (using the "request": "attach" configuration).

Thanks for the reply. I'll have a try on the "attach" mode.

"request": "attach" configuration

I tried the attach configuration, unfortunately it didn't work.

To reproduce

% cd kotlin-quick-start

./gradlew run --debug-jvm

> Task :run
Listening for transport dt_socket at address: 5005

Run the Kotlin Attach config in vscode. But got the message below:

[INFO] main      Connected to client
[INFO] async0    Waiting for configuration done response for 10 seconds...
[INFO] async0    Waiting for configuration done response for 20 seconds...
[INFO] async0    Waiting for configuration done response for 30 seconds...
[INFO] async0    Waiting for configuration done response for 40 seconds...
[INFO] async0    Waiting for configuration done response for 50 seconds...
[INFO] async0    Waiting for configuration done response for 60 seconds...
[INFO] async0    Waiting for configuration done response for 70 seconds...
...

My launch.json is:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "kotlin",
            "request": "attach",
            "name": "Kotlin Attach",
            "projectRoot": "${workspaceFolder}",
            "hostName": "localhost",
            "port": 5005,
            "timeout": 30000
        },
        {
            "type": "kotlin",
            "request": "launch",
            "name": "Kotlin Launch",
            "projectRoot": "${workspaceFolder}",
            "mainClass": "MainKt",
            "preLaunchTask": "build"
        },
        {
            "type": "java",
            "name": "Java Debug (Attach)",
            "request": "attach",
            "hostName": "localhost",
            "port": 5005
        }
    ]
}

The Java Debug(Attach) works. It correctly attached and showed call stack. (Of cause it doesn't recognize kotlin breakpoints though.)

It worked when I build the kotlin-debug-adapter locally. Maybe the one in the latest-release is out of date.
Anyway thank you for your advice!
