Thank you for directing me to the Brave git repository. Please bear with me a bit if you can stand it. I have worked with git a little and also with other forms of version control systems, but not enough.
I am posting a few observations and hoping you can provide a very quick sanity check, and also hopefully, my understanding is sane.
The nightly build version of Brave Browser appears to be produced exclusively from the brave-core repository. Also appears the nightly version is released usually once per day, often twice per day, but Christmas day was skipped.
Looks like I should be able to build my own copy of the Brave browser nightly release, that would be an exact match with official releases. In doing so, I could (or would have to) have a copy of all the source code on my computer. That is unbelievably awesome to me.
Ummmm, I thought of something I might be missing. I run macOS. C++ is Micro$oft.net technology. Either Bill Gates/Microsoft have reinvented themselves since I last spent time inside Windows-based systems, or working with C++ on macOS is going to be forcing a pig to fly. Based on the similarity between Bill Gates proselytizing Windows 1995-2000 and Bill Gates proselytizing vaccines 2010-present, and cross-checked with the world of Windows Subsytem for Linux, I foresee agony building Brave Browser on macOS.
