Is there an ETA for a fix here? It's not clear how to manually trigger the checks, and debugging Closure Compiler complaints via the trybots is a slow and painful process.

thanks!

Sorry for taking a while - will have a fix soon. Meanwhile, you can run Closure compiler on devtools manually by going to: ~/chromium/src/third_party/WebKit/Source/devtools/scripts and running "python compile_frontend.py".

Thanks.

elawrence@ - I landed a patch that fixes the presubmit hooks for Windows using cmd. There's still some issues left with cygwin so I'll leave this ticket open, but let me know if you still run into any issues.

I left this open because of some cygwin issues, but it seems like there's few Chromium developers using cygwin so I'm closing this.
