My user.lua custom settings file.
Font definition and size (8pt) (need RobotoMono installed), multiple style.defines (copied from my TwoDark theme), and various editor settings (usetabs = true, tabwidth = 4 (really, there's no other acceptable tab setting... :), backspaceunindent = true, foldcompact = false, edge = true, wrapstartindent = 4)
TwoDark - A theme based on the OneDark syntax theme from the Atom editor. This theme is built around Roboto Mono, a tasty monospaced font from Google Google Fonts.
