Cinder

Trace Example

Note: This example misbehaves under Chromium for understood reasons, which I believe constitute a bug in Chromium. A workaround is known. but would be very complex for this piece and render it unfit as an example. Please view in Firefox for correct behaviour

This is the only example that doesn't start with an empty SVG file. I made it in Inkscape, converting the text to paths. The animation code is here:

nifty = root >>= byTag "path" >>= mapM (tracePath 0.5 1)
        >>= stagger "begin" 0 0.5 >> return ()

After retrieving the document's root Node, it asks for a list of path Nodes and calls tracePath for each of them, with a duration of a half-second. tracePath is impure, because it has to query the node for its length. The nodes are then scheduled to start a half second apart, and that's it.

Note mapM is not part of the (Fay) Prelude but is one of several functions from Control.Monad for which Cinder provides monomorphic equivalents in Control.Fay.
