trace_viewer depends on py-chrome-app which is busted with latest chromes

I've tried to use this app by following the "QuickStart" instructions, but I get the following error when running it:
Exception: Could not find trace_event_viewer/third_party/trace-viewer/src/timeline_view.js

I copied timeline_view.js the trace-viewer project (trace_viewer/tracing/timeline_view.js) into third_party/trace-viewer/src, but I then get an error like:
timeline_view.js:680: Uncaught ReferenceError: tvcm is not defined

I tried on both Ubuntu and Mac. Totally willing to help fix this if you can give me a hint for what might be going wrong.

Hmmm I tried doing some of the fixes for this (update the third_party/trace-viewer to trace-viewer ToT and then update all the module names to the latest folder layout of trace viewer. build has moved to trace_viewer/build, amongst other things). That gets rid of the error your were seeing --- I'll push a change for that.

But, the actual viewer isn't actually working yet. :( This project relies on chrome apps apis to launch the UI. These keep breaking to the point that I rather gave up on them. A step to making this work again would be to go into third_party py-chrome-app/ and see if you can get the unit tests passing there...

For what its worth, the futility of chrome apps apis working right on desktop is what led me to write trace-viewer/trace2html which just takes a trace file and turns it into an html file that you can then open in any old browser. It doesn't give you the illusion that its an "app" like this project is trying to do, but it works for day to day stuff...
