Subject Re: Code inspection
Date Mon, 22 Apr 2019 21:25:05 GMT
Maxim, I merged your changes to master.

Also, I've created a new build plan "Check Code Style" on TC [1] and
included in RunAll build.
The report of check-style attaches in artifacts once build is finished.

Please check that it works as expected once again and announce new
requirements in a separate thread to avoid confusion of community.

cc Petr, Pavel (JFYI)
