My Atom configs

init.coffee

# Your init script
#
# Atom will evaluate this file each time a new window is opened. It is run
# after packages are loaded/activated and after the previous editor state
# has been restored.
#
# An example hack to make opened Markdown files always be soft wrapped:
#
# path = require 'path'
#
# atom.workspaceView.eachEditorView (editorView) ->
#   editor = editorView.getEditor()
#   if path.extname(editor.getPath()) is '.md'
#     editor.setSoftWrap(true)

atom.commands.add 'atom-text-editor:not(.mini)',
  "editor:tab": (event) ->
    event.stopPropagation()
    editor = @getModel()
    editor.transact editor.getUndoGroupingInterval(), ->
      editor.insertText('\t')
