How to re-map subword movement?

[eyaleizenberg]

I want to remap space-w, space-e, space-b, space-d, space-D for example to do the appropriate subword actions (move to next subword, end of next subword, back subword, delete subword, delete subword back).

However, I can't get the mappings to work for me? Can you please post examples of the correct key mappings for this?

Thanks a lot! This package is a life saviour!

Check list

• Atom version info(atom --version)
• vim-mode-plus version.
• Your OS(e.g. macOS Sierra 10.12.3)
• You disabled vim-mode? You cannot use both vim-mode and vim-mode-plus simultaneously.
• Tried to latest stable atom version with latest vim-mode-plus.
• Keybinding issue? Read this.
• If you follow Ideal issue reporting, it's great!

Here is answer and how you can do by yourself next time.

HowTO and Answer

1. Find where similar command are defined in default keymap.

In this case, find w here. https://github.com/t9md/atom-vim-mode-plus/blob/master/keymaps/vim-mode-plus.cson#L66

2. define keymap in your keymap.cson with same keymap scope.

You can open your keymap by invoking Open Your Keymap command from command-palette.

'atom-text-editor.vim-mode-plus:not(.insert-mode)':
  'space w': 'vim-mode-plus:move-to-next-word'
  'space b': 'vim-mode-plus:move-to-previous-subword'
  'space e': 'vim-mode-plus:move-to-end-of-subword'

For space d to delete subword mapping, you cannot do it unless you define your own custom operator or hack keymap system.

But you can map d ANYKEY to delete subword.

With following example, you can d x to delete subword TextObject.

'atom-text-editor.vim-mode-plus.operator-pending-mode.delete-pending':
  'd x': 'vim-mode-plus:inner-subword'

Btw, vim-mode-plus have following default keymap.

• i d(inner-subword)
• a d(a-subword)

So you can do d i d to delete subword without any custom keymap.

@t9md Thanks a lot! The d i d is really useful. Thanks!

Btw, vmp have shorthand keystroke(= one-keystroke text-object shorthand).

https://github.com/t9md/atom-vim-mode-plus/blob/0aac87e6ec6683f23b8a0fa539f19811021c8795/keymaps/vim-mode-plus.cson#L490-L496

So you can type

• y p, instead of y i p.
• y , instead of y i ,(argument TextObject)
• y d instead of y i d(subword)

You can swap y(yank) operator with any other operator like c p, c ,, c d.

But d d doesn't work as delete subword. since y y, d d, c c have have special meaning, so one-key shorthand keymap is disabled in conflicting case like this.

These keymaps are available only in operator-pending mode(in other words, it's not available in visual-mode).

If you want use c c to change word too. You can enable it via configuration keymapCCToChangeInnerSmartWord.
