Configure code folding in Atom to mimic PatentStorm

Question

In PatentStorm, I used Ctrl+W — Ctrl+Shift+W to fold / unfold code.

I migrated to Atom — is this possible to mimic?

Answer 1

Custom Keymap

Add this to your keymaps:

'atom-text-editor':
  'ctrl-w': 'editor:fold-current-row'
  'ctrl-shift-w': 'editor:unfold-current-row'

Atom Defaults (Windows)

You can fold blocks of code by clicking the arrows that appear when you hover your mouse cursor over the gutter. You can also fold and unfold from the keyboard with the Alt+Ctrl+[ and Alt+Ctrl+] keybindings.

Single Key Fold-Toggling

If you'd like to use a key binding to fold-toggle, create a custom command:

atom.commands.add 'atom-text-editor',
  'editor:toggle-current-row-folding': (event) ->
    editor = @getModel()
    bufferRow = editor.bufferPositionForScreenPosition(editor.getCursorScreenPosition()).row
    if editor.isFoldedAtBufferRow(bufferRow)
      editor.unfoldBufferRow(bufferRow)
    else
      editor.foldBufferRow(bufferRow)

Here you would use 'editor:toggle-current-row-folding' as your command.
