Ⅳ. 文档说明

# LessSpace.vim

This simple plugin will strip the trailing whitespace from the file you are editing.
However, it does this only on the lines you edit or visit in Insert mode; it leaves all the others untouched.

I wrote this plugin because I work with people whose editors don't clean up whitespace.
My editor (Vim) did strip all whitespace, and saving my edits caused a lot of extraneous whitespace changes that showed up in version control logs.
This plugin gives the best of both worlds: it cleans up whitespace on edited lines only, keeping version control diffs clean.

Installation

If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:

cd ~/.vim/bundle
git clone git://github.com/thirtythreeforty/lessspace.vim

Usage

For basic usage, just install it and forget it.
LessSpace works automatically.

LessSpace provides a couple commands that allow you to turn it on or off, either globally or per-buffer.
The global commands are:

• LessSpace: Turn on whitespace stripping
• LessSpace!: Turn off whitespace stripping

The per-buffer commands are very similar:

• LessSpaceBuf: Turn on whitespace stripping
• LessSpaceBuf!: Turn off whitespace stripping

Configuration

LessSpace doesn't offer many configuration options, because everything happens automatically when you enter and leave Insert mode.

You can disable LessSpace on startup by setting the g:lessspace_enabled variable:

let g:lessspace_enabled = 0

(The same effect can be achieved after startup by just running :LessSpace!.)

By default, LessSpace strips whitespace after normal mode operations (such as when you paste something from a register).
If you don't want this, you can have LessSpace only work in insert mode by setting g:lessspace_normal:

let g:lessspace_normal = 0

You can also specify the filetypes that it operates on by specifying a filetype whitelist or blacklist.
(Perhaps, for example, you're writing Whitespace.)
You can change this by setting either of the g:lessspace_whitelist or g:lessspace_blacklist variables, preferably in your vimrc file.
These variables should be lists of the desired filetypes.
For example, to only operate on Vim and Ruby files, you could use:

let g:lessspace_whitelist = ['ruby', 'vim']

And to operate on everything but diff files (this is the default):

let g:lessspace_blacklist = ['diff']

(Previously, the whitelist had to be specified as a regex string.
This has been deprecated and removed; you should update to the list-based method.)

Integrating

If LessSpace bothers your plugin, you can call these functions to temporarily disable it while your plugin runs:

call lessspace#TemporaryDisableBegin()
call lessspace#TemporaryDisableEnd()

In such cases, please file an issue on GitHub to see if we can make the integration better!
