Implement io.Writer for File #129

Open mattes opened 5 years ago

mattes commented 5 years ago

It would be nice if type File would implement io.Writer. That way I could update some static files on the fly when served via http.FileServer(box.HTTPBox()).

So, writing to the file would completely overwrite? Or would it append? I'm not sure if this is something rice should do itself; or if it would be something for a layer in between http.FileServer and box.HTTPBox().

It would probably be cleaner to implement a separate package that provides a http.FileSystem by wrapping an existing http.FileSystem (e.g. box.HTTPBox()), but allows for modifications/overwrites. It first checks its local changeset, if there's no matching file, then forwards the Open(..) call to the wrapped http.FileSystem.

Probably interesting to look at for this: https://github.com/spf13/afero
