[20131125]使用vim做合計計算.txt

工作需要,需要使用vim做合計計算,把一列的資料累加,輸出結果,到網站檢索,發現:

http:///scripts/script.php?script_id=1932

visSum.vim外掛比較合適.結果測試發現一些問題,結果自己花了一個下午晚上的時間測試修改,有點浪費時間.
主要原因:
1.不熟悉vim裡面的函式,以及命令格式.
2.vim scripts 不知道如何除錯,我最後只能單步跟蹤執行.
3.作者使用摺疊功能,自己還花一點時間學習這方面的知識.

最後指令碼修改如下:

VimSum.vim指令碼如下,點選(此處)摺疊或開啟

\" 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.
\" ==========================================================================
\" Exit quickly if the script has already been loaded
let s:this_version = \'1.0\'
if exists(\'g:loaded_visSum\') && g:loaded_visSum == s:this_version
finish
endif
let g:loaded_visSum = s:this_version
\"Mappings {{{
\" clean up existing key mappings upon re-loading of script
if hasmapto(\'SumNum\')
nunmap \\su
vunmap \\su
nunmap SumNum
vunmap SumNum
endif
\" Key mappings
nmap su SumNum
vmap su SumNum
if has(\'float\')
\" Call the floating-point version of the function
