这个也是main函数开始的，下面就是最后一行代码，表示export出rSo 函数作为它的名字公开为main, 和dll export表有点像了。

	export {rSo as main}; 

其中rSO是

function rSo(i) {return new nSo(i).open()
}

nSO是一个类，应该是就是workbenchMain了。

var nSo = class extends V {constructor(i) {super(), this.a = i, this.b()}b() {this.c(), fle(!!this.a.fullscreen, _t)}c() {const i = YCn(this.a.workspace);(oN(i) || mC(i)) && (this.a.workspace = i);const e = this.a.filesToWait,t = e ? .paths;for (const s of [t, this.a.filesToOpenOrCreate, this.a.filesToDiff, this.a.filesToMerge])if (Array.isArray(s))for (const n of s) n.fileUri && (n.fileUri = W.revive(n.fileUri));e && (e.waitMarkerFileUri = W.revive(e.waitMarkerFileUri))}async open() {const [i] = await Promise.all([this.j(), H0n(_t)]);this.f(i.configurationService);const e = new T0o(_t.document.body, {extraClasses: this.g()}, i.serviceCollection, i.logService);this.h(e, i.storageService);const t = e.startup();this.D(t.createInstance(dCt))}f(i) {let e;if (this.a.isCustomZoomLevel && typeof this.a.zoomLevel == "number") e = this.a.zoomLevel;else {const t = i.getValue();e = typeof t.window ? .zoomLevel == "number" ? t.window.zoomLevel : 0}rxe(e, _t)}g() {return Bt && LRi(this.a.os.release) ?
