Atom.Object.defineProperty.get is deprecated.

[efposadac]

atom.workspaceView is no longer available.
In most cases you will not need the view. See the Workspace docs for
alternatives: https://atom.io/docs/api/latest/Workspace.
If you do need the view, please use atom.views.getView(atom.workspace),
which returns an HTMLElement.

Atom.Object.defineProperty.get (/Applications/Atom.app/Contents/Resources/app/src/atom.js:55:11)
Object.activate (/home/fernando/.atom/packages/rst-preview/lib/rst-preview.coffee:16:9)
