Extract to constant in enclosing scope should optionally also replace later usage

Given this code:

	public setParts(lineNumber: number, parts: GhostTextPart[]): void {
		const foreground = this.themeService.getColorTheme().getColor(ghostTextForeground);
		let opacity: string | undefined = undefined;
		let color: string | undefined = undefined;
		if (foreground) {


			opacity = String(foreground.rgba.a);
			color = Color.Format.CSS.format(opaque(foreground))!;
		}

		const borderColor = this.themeService.getColorTheme().getColor(ghostTextBorder);
		let border: string | undefined = undefined;
		if (borderColor) {
			border = `2px dashed ${borderColor}`;
		}

I would like to factor our this.themeService.getColorTheme() and extract it into its own constant. This should include all later usages.
Since there could be side effects in between, I suggest to do it only if later occurences are also selected.

This is my current workflow and I don't feel smart doing it like that. Multicursors don't really help here.

Also, it would be nice if the name of the new local is heuristically derived from the expression ((...).getFooBar(...) -> fooBar`).

I'm willing to do a PR if I get some pointers.

Let's make the editing experience in VS Code even more amazing 😉

Commencez par localiser l’implémentation de la refactorisation extract-to-constant et ses tests dans le dépôt TypeScript. Reproduisez ensuite l’exemple TypeScript présenté, puis suivez la manière dont les limites de la sélection et les occurrences ultérieures sont gérées. Le travail est terminé lorsqu’une extraction facultative de la portée englobante peut inclure les utilisations ultérieures uniquement lorsqu’elles sont sélectionnées, le nommage heuristique étant considéré séparément.
