In Visual Studio Code, in the launch.json file that launches the app I'm writing, how do I add command line arguments?

As described in the documentation, you need to use the args attribute. E.g.
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug App",
"program": "${workspaceFolder}/main.js",
"args": ["arg1", "arg2", "arg3"]
}
]
}

@eigenfield have you tried filing a bug report with Visual Studio Code or Kotlin?
Muhammad Awais
just to clarify args array,
"args": ["key=value", "key=value"]Jonathan Benn
@AwaisNasir is that suggestion for Kotlin? Or in general? In practice, I've used simple strings and not key-value pairs.

@JonathanBenn I don't know about kotlin, thats the general solution, for me key value pair solution worked and not simple strings

If I run this as is, I get an error:
launch: property 'cwd' is missing or empty. I had to manually add this line to the launch.json to get it to work ``` "cwd": "${workspaceFolder}" ``` |
I pass arguments by this way for the python program, it may work for nodejs:
{
"type": "node",
"request": "launch",
"name": "Debug App",
"program": "${workspaceFolder}/main.js",
"args": ["--arg1", "value1", "--arg2", "value2"]
}

It worked. Thanks
In settings.json in the .vscode folder you can pass an env file.
settings.json
{
"python.testing.pytestArgs": [
"."
],
"python.testing.unittestEnabled": false,
"python.testing.pytestEnabled": true,
"python.envFile": "${workspaceFolder}/env"
}
and the env file
FLASK_ENV=test

settings.json and launch.json are different files for different purposes. And yes, launch.json exists on macOS too, it is just not created out of the blue, it is created when a run configuration is created.
%runmagic command. See stackoverflow.com/a/78102091/3057377
