Ⅳ. 文档说明

# vmath.vim

Damian Conway's vmath plugin for vim as demonstrated at his OSCON 2013
"More Instantly Better Vim" presentation. Calculates the sum, average,
min, and max for a visual region containing numbers.

Installation

Copy vmath.vim to ~/.vim/plugin:

cp ./plugin/vmath.vim ~/.vim/plugin/

or use tpope's pathogen:

cd ~/.vim/bundle
git clone git://github.com/nixon/vim-vmath.git

Usage

Add the following key maps to ~/.vimrc:

vmap <expr>  ++  VMATH_YankAndAnalyse()
nmap         ++  vip++

Start vim, use visual mode to highlight a set of numbers, and use ++.
The result will be output like:

sum: 21   avg: 3.5   min: 1   max: 6   count: 6

The results are also stored in the following registers:

  • s : sum
  • a : average
  • n : min
  • x : max
  • c : number of items
  • r : range

which can then be pasted with "sp, etc. The sum is also available in
the default yank buffer so it can be easily pasted with p.
