Was advanced Vim user

vim-chef, vim-xmpfilter, textmanip, choosewin, quickhl, smalls...

Am Atom with vim-mode-plus user

vim-mode-plus, cursor-history, open-this, quick-highlight, project-folder...

What makes me editor addict is difficulties and limitless enhanceability of Emacs.

What is the vim-mode-plus?

Started by forking vim-mode maintained by GitHub

Forked at 2015.08
Public release at 2015.09.28
Now 104 releases(!!) from initial release at 2016.11.04(about 1 release/4 days)
Now de facto vim keybinding in Atom?

vim-mode's README was updated yesterday(2016.11.04)

Current Status - DEPRECATED in favor of vim-mode-plus

It's honor to be used by really talented programmers(jordwalke, chenglou, rtfeldman).
Happy to be mentioned in JavaScriptAir 034

What I did from when I forked

Refactoring
- Rewrote every lines of codes. Greatly reduced complexity.
Add lot's of new features:
- incremental-search
- visual-block-mode
- surround
- any-pair text-object
- occurrence operator-modifier
- persistent-selection
Off course, thanks to great vim-mode
- Sincerely, I feel I couldn't do anything without original vim-mode.

Editing in the vim-world

The editing is transforming state of text by mutation.
initial-text -> mutate -> final-text
Mutating text with operator and target by telling vim to "do what on which target".

Subjects, Verbs and Objects basic operation unit

Subject is You.
Verb: is Operator
- Specify what to do. The verb requires an object(=target).
- Do mutation(Delete , Yank , CamelCase )
Objects: is Target(Motion or TextObject)
- Specify where, which to apply an operators on.
- i w(inner-word text-object), j(from-here-to-next-line)

How operation-stack of vim-mode-plus is working.

Motion is complete?

Operator is complete?

class DeleteToLastCharacterOfLine extends Delete
  @extend()
  target: 'MoveToLastCharacterOfLine'
  execute: ->
    if @isMode('visual', 'blockwise')
      swrap.setReversedState(@editor, false)
    super

Operation life in operation-stack

execute operation when it's complete!

OperationStack code

    top = @peekTop()
    if top.isComplete()
      @execute(@stack.pop())
    else
      if @mode is 'normal' and top.isOperator()
        @modeManager.activate('operator-pending')

      # Temporary set while command is running
      if commandName = top.constructor.getCommandNameWithoutPrefix?()
        @addToClassList(commandName + "-pending")

vim-mode-plus original features

YouDontKnowVimModePlus

Maximize current pane
Incremental search
flashOnOperate and flashOnUndoRedo
StayOn family(stayOnTransformString, stayOnYank, stayOnDelete)
Motions: MoveDownToEdge, MoveToNextNumber, MoveToNextString
TextObject: AnyPair, Indentation, Entire(All), Fold, Function, Comment
Operator: Lots of string transformer(Sort, CamelCase, SnakeCase, Surround, ToggleLineComments, ReplaceWithRegister etc..)
Operator: Meta string transformer (TransformStringBySelectList).
Narrowed selection. cmd-d(select-occurrence), ctrl-cmd-c(change-occurrence).
Super granular keymap scopes(e.g. mapping only effective when toggle-line-comments-pending)
Persistent-selection: works as like normal visual-selection but you can make selection persist.

Keep cursor position by operator.

Side-effect-less operator by stayOnYank, stayOnDelete and stayOnTransformString
In pure-Vim, y i p move cursor to start of yanked area.
I want cursor move only when I said so. Don't move unless I said so .

But cursor movement convinces user the success of an operator.
Just dont-move-cursor is not enough, flashOnOperate compliment user's confidence.

Occurrence modifier, preset-occurrence, persistence-selection

As like you can force-wise of operator by d v j, o modifies operator's behavior to works on occurrences within target.
A preset-occurrence allows you to set occurrence preliminarily.
ctrl-o in incremntal-search allows you to set preset-occurrence by regex pattern
- e.g. / ^ # * $ ctrl-o g U i e uppercases all lines starts with #.
Also a persistent-selection allows you to pre-specify a target of operator.

Sometimes, replacing single-char in bulk is faster than repeating operator.

Repeat(`.`) delete-surround

delete-surround with multiple cursor

preset-occurrence for single quote `'` then apply delete operator.

So what am I doing in vim-mode-plus?

vim-mode-plus is not trying to be complete-Vim
- Impossible and no motivation for that.
- Atom is NOT Vim.
vim-mode-plus is aggressively evaluating how effective-editing-would-be.
- How is it like when xxx is yyy.
- Is zzz feature is really practically(not conceptually) useful?
Thinking about Vim deeply further than I was pure-Vim user.
- And always found pure-Vim's really careful and maniac decision for developer's intuitiveness/productivities.
