# Deprecated: Represents the entire visual pane in Atom.
#
# The TextEditorView manages the {TextEditor}, which manages the file buffers.
# `TextEditorView` is intentionally sparse. Most of the things you'll want
# to do are on {TextEditor}.
#
# ## Examples
#
# Requiring in packages
#
# ```coffee
# {TextEditorView} = require 'atom'
#
# miniEditorView = new TextEditorView(mini: true)
# ```
#
# Iterating over the open editor views
#
# ```coffee
# for editorView in atom.workspaceView.getEditorViews()
# console.log(editorView.getModel().getPath())
# ```
#
# Subscribing to every current and future editor
#
# ```coffee
# atom.workspace.eachEditorView (editorView) ->
# console.log(editorView.getModel().getPath())
# ```
