Graphical tools and packages in Go.
editor provides a graphical, editable text area widget.
cmd/edit is an almost-pure-Go text editor which uses the editor package, and is intended to resemble acme without the window management — for now, at least. The non-pure-Go part is the shiny driver, though in theory a pure-Go shiny driver could be developed (e.g. using Plan 9's /dev/draw, or Linux's frame buffer device).
