Notational Conventions

This section describes the conventions used here to describe type signatures.

A [T] is an array-like value (only ever used read-only in this API), i.e., one with an integer length and whose indexed properties from 0 to length - 1 are of type T.

A type T? should be read as T | undefined -- that is, an optional value that may be undefined.

Answer by Jim Dennis on Stack Overflow question http://stackoverflow.com/questions/1218390/what-is-your-most-productive-shortcut-with-vim/1220118#1220118

Your problem with Vim is that you don't grok vi.

You mention cutting with yy and complain that you almost never want to cut whole lines. In fact programmers, editing source code, very often want to work on whole lines, ranges of lines and blocks of code. However, yy is only one of many way to yank text into the anonymous copy buffer (or "register" as it's called in vi).

The "Zen" of vi is that you're speaking a language. The initial y is a verb. The statement yy is a simple statement which is, essentially, an abbreviation for 0 y$:

0 go to the beginning of this line. y yank from here (up to where?)

1. Introduction

Since the birth of the software development discipline, programmers have dedicated time and effort into creating digital tools that optimize the process of going from an initial idea to a fully fledged product. This task is a hard one. How do you model a tool to support the non-linear, unstructured process of thinking? How do you create a tool that allows you to turn your thoughts into a digital document? A tool where you can build upon this document, iterate away on tangents when you get inspired, and quickly revert to a former state if this proved unsuccessful? More important, how do you create a tool that allows a group of people to collaborate on the same project, when that project doesn't have a structured form yet?

One answer to this question is the concept of a version control system, that today plays a central role in any serious software development project. It allows individuals to iterate code-based projects in a flexible environment, and to share these improvements with collabora
