Yes, it’s closed source. So are iTunes, Adobe Photoshop, and Maya. You want open source build it yourself. I’ve personally used it for over 3 years now and felt I needed to express how completely I love it. As a computer architect I work on Windows, Linux, and Mac. Sublime follows me on any of them. It is customizable to any extent I’d require, and has all the features I need and more besides that make using it a joy (built-in code repl and sort-F9, etc.)
I’ve personally used it to load 100Mb + text files, with no ill effects, including performance degradation to my system.
Lastly I’m a paranoid C99 hacker at heart, and love the fact that Sublime runs without any VM, support software or internet connectivity.
My sincere thanks to the developer for 3 years of coding joy, and high hopes for many more.
