This package provides a simple wrapper for the
or rather the function
enabling you to write
gloss applications as signal functions.
An example “gears” program, which you can run as
cabal run rhine-gloss-gears
stack build && stack exec rhine-gloss-gears,
now becomes as simple as:
import FRP.Rhine.Gloss -- | Calculate a gear wheel rotated by a certain angle. gears :: Float -> Picture gears angle = color green $ pictures $ circleSolid 60 : map (rotate angle) [ rotate (45 * n) $ rectangleSolid 20 150 | n <- [0..3] ] -- | Rotate the gear with a constant angular velocity. mainClSF :: GlossClSF a mainClSF = timeInfoOf sinceInit >>> arr (* 50) >>> arr gears main :: IO () main = flowGloss (InWindow "rhine-gloss-gears" (400, 400) (10, 10)) (greyN 0.3) 30 $ buildGlossRhine Just mainClSF

you will need to install the same dependencies as for that.
Typically, this are the
When building with
stack, it is assumed that you have
which will automatically get these dependencies for you.
