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.

"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug App",
"program": "${workspaceFolder}/main.js",
"args": ["arg1", "arg2", "arg3"]
}
]
}

@AwaisNasir is that suggestion for Kotlin? Or in general? In practice, I've used simple strings and not key-value pairs. Commented Jul 2, 2021 at 12:35

1@JonathanBenn I don't know about kotlin, thats the general solution, for me key value pair solution worked and not simple strings Commented Jul 2, 2021 at 12:43

1If 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": "${workspaceFolder}" ``` Commented Sep 7, 2022 at 3:36
I pass arguments by this way for the python program, it may work for nodejs:
{
"type": "node",
"request": "launch",
"name": "Debug App",
"program": "${workspaceFolder}/main.js",
"args": ["--arg1", "value1", "--arg2", "value2"]
}

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
andlaunch.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.– axiacCommented Jan 9 at 16:16
%run
magic command. See stackoverflow.com/a/78102091/3057377
