I'm t9md

1. Was normal Vim user
2. Was advanced Emacs user.
3. Was advanced Vim user
   • vim-chef, vim-xmpfilter, textmanip, choosewin, quickhl, smalls...
4. 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?

classDeleteToLastCharacterOfLineextendsDelete@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()iftop.isComplete()@execute(@stack.pop())elseif@modeis'normal'andtop.isOperator()@modeManager.activate('operator-pending')# Temporary set while command is runningifcommandName = 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.

Thanks!!

Vim!! You are great!

Atom! You are great!

Vim-mode! Without you, I don't think I could create vim-mode-plus from scratch.

Japanese Vim community! Love friendly atmosphere and lots of super aggressive/good plugin authors and contributers to core.
