Fay Canvas

Canvas bindings for Fay. This project is experimental and not suitable for production purposes.

The intent of this library is to be a 1-to-1 mapping of existing Canvas API calls in order to build more idiomatic library for Fay.

Usage

To use this with fay, cabal install the package which will put the source files in fay ~/.cabal/share/fay-jquery-0.0.1.0/src. You can then compile with fay using

in fay >= 0.12:

fay --package fay-canvas MyFile.hs

in fay < 0.12:

fay --include=~/.cabal/share/fay-canvas-0.0.1.0/src MyFile.hs
