Reference a fixed JSON file

[VaniSachdev]

I’m following along the tree-view sample, and my goal is for the JSON file the tree view is created from to be hard coded into the extension (the path of a specific JSON file) such that regardless of which file is open the tree view is the same. Currently the code is dependent on the active editor being a JSON file, and I assumed it would be an easy proof of concept if I could hardcode the active editor to reference a specific path somewhere in the constructor but I haven't been able to figure it out. I'm fairly new to developing VS Code extensions (& typescript!), so any help would be great!

I suppose you are looking for customizing the parseTree function, which in that sample, is responsible to load the JSON file from the active editor, as you can see:

	private parseTree(): void {
		this.text = '';
		this.tree = null;
		this.editor = vscode.window.activeTextEditor;
		if (this.editor && this.editor.document) {
			this.text = this.editor.document.getText();  <<-- HERE
			this.tree = json.parseTree(this.text);
		}
	}

In your case, line 86 it the one responsible for that. Replace it with your custom JSON file and you are good to go.

Hope this helps
