Acme9k is my personalized fork of the plan9port editor/IDE Acme. It is a fork which combines the customizability of a project like dwm with various graphical and behavioral improvements that have not yet made it upstream and a modest selection of scripts and structural regular expressions that streamline acme's UX as an IDE.

Additionaly, there is a fork of the libframe library in the distribution which enables the active frame to show a differently-clored cursor; if using click-to-focus via the -b flag, there is in vanilla acme no visible indication of the active frame until you start typing, and this solves that problem.
