An API client for Instructure's Canvas API.

go get github.com/harrybrwn/go-canvas

1. Get a token from your canvas account, this should help.
2. Give the token to the library
   • Set $CANVAS_TOKEN environment variable
   • Call canvas.SetToken or canvas.New
3. For more advance usage, viewing the canvas API docs and using the canvas.Option interface will be usful for more fine-tuned api use.

Error handling for functions that return a channel and no error is done with a callback. This callback is called ConcurrentErrorHandler and in some cases, a struct may have a SetErrorHandler function.

canvas.ConcurrentErrorHandler = func(e error) error {
    if canvas.IsRateLimit(e) {
        fmt.Println("rate limit reached")
        return nil
    }
    return e
}
for f := range canvas.Files() {
    fmt.Println(f.Filename, f.ID)
}
