$ echo 'local cairo = require("lgi").cairo local surface =

$ feh /tmp/foo.png
[Displays some random character from my terminal]
Same code with some more line breaks:
local cairo = require("lgi").cairo
local surface = cairo.ImageSurface(cairo.Format.RGB24, 20, 20)
local cr = cairo.Context(surface)
cr:set_source_surface(require("gears.surface")(client.focus.content), 0, 0)
cr:paint()
surface:write_to_png("/tmp/foo.png")'
Cheers,
Uli
