How to find out which extension provided the command in vscode? - visual-studio-code

Question

I'm clueless what feature came out of which extension, is there a way to have its source displayed?
Also would be interesteed to know if its possible to trace the source code of the features.

Answer 1

The only thing I can think of is checking the package.json files, as even vscode.commands.getCommands() only returns plain strings. This can be done with the vscode.extensions API:
import * as vscode from 'vscode';
export function activate(context: vscode.ExtensionContext) {
setTimeout(() => {
for (const extension of vscode.extensions.all) {
let commands = extension.packageJSON.contributes?.commands;
if (!Array.isArray(commands)) {
continue;
}
for (const command of commands) {
console.log(command.title + " is from " + extension.id);
}
}
}, 2000);
}
Note that all only includes activated extensions, hence the timeout to make sure all extensions that activate on startup are done with their activation.

Answer 2

what feature came out of which extension
Yes, you can do this, taking advantage of VSC's intellisense:
I'm Assuming (1) by feature, you mean a command executable from the command pallette and
Open keybindings.json in vscode
You should see JSON like below; if not, add one like below (you're not going to keep it).
{
"key": ".",
"command": "REPLACE THIS WITH YOUR COMMAND NAME",
"when": "suggestWidgetVisible"
}
Where it says "REPLACE THIS WITH YOUR COMMAND NAME", begin typing the name of the command you're interested in
The VSC suggestion widget will open, showing roughly EXTENSION_NAME.YOUR_COMMAND. If the suggest widget doesn't open, press ctrl+space to open it.
Note the name of the extension; that's what contributed that feature/command. If the name doesn't match an extension, it's probably a core VSC feature
trace the source code of the features
Most extensions are on GitHub, as is the core code for VSC, so you can simply navigate to the relevant repository and seacrch the code for that command.

Check this link out from VS Code documentation.
Here you can see where the extensions are installed by default.
And further, you can access their source code.
Where are extensions installed?
Extensions are installed in a per user extensions folder. Depending on your platform, the location is in the following folder:
Windows %USERPROFILE%\.vscode\extensions
macOS ~/.vscode/extensions
Linux ~/.vscode/extensions
You can change the location by launching VS Code with the --extensions-dir command-line option
About which feature cames from which extension, I'm not sure if it's possible to achive that.

Answer 4

Click on an extension and in the editor that opens showing its readme, click on the Feature Contributions link and you'll see the settings and commands that extension contributes. For example:
