[20200424]vim visSum.vim合计插件.txt


--//别人问的问题,下载新的插件visSum.vim,问以前脚本如何做到直接在文件插入合计,作者的版本仅仅在提示行显示结果。

--//对方应该使用链接上的插件:http://blog.itpub.net/267265/viewspace-2140889/

--//我重新下载这个插件测试看看,修改如下:

" File:         visSum.vim (global plugin)
" Last Changed: 2015-08-18
" Maintainer:   Erik Falor <ewfalor@gmail.com>
" Version:      1.2
" License:      Vim License
"
" This version (1.2) contains a fix for a bug reported by Fabio Inguaggiato.
" Thanks, Fabio!
"
" Version (1.1) contains a fix for a bug reported by Markus Weimar.
" Thank you, Markus!
"
" A great big thanks to Christian Mauderer for providing a patch for
" floating-point support!

" This plugin will work whether or not your Vim is compiled with support for
" floating-point numbers.  If your Vim doesn't has('float'), we'll just
" ignore whatever comes after the decimal point.
"
" Due to the way Vim parses floating-point numbers, the only valid separtator
" between the whole and fractional parts of the number is a period.  Vim
" won't accept a comma, even if that's your locale's preference.  This
" plugin follows that convention.

--//仔细看看一下下划线的内容。
--//另外简单说明
--//这个插件选择范围必须从左到右或者从上到下选择范围,并且最后一列最好最长,不然丢失精度,而且vim仅仅支持小数点6位。
--//另外从官方下载的vim缺省是支持float功能的,理论讲是不会调用SumNumbers_Int函数,所以SumNumbers_Int我没有修改。

--//例子:
red   1.1
black 2.100001
blue  3.1
white 4.12
sum = 10.42
--//丢失精度,修改如下:

red   1.1
black 2.100001
blue  3.1
white 4.120000
sum = 10.420001

--//修改如下:
red   1.1
black 2.100001
blue  3.1
white 4.12000012
sum = 10.420001
--//精度只能到小数点6位。我自己也很少使用这个插件。
