some vim

something is fun from learning the vi editor 6/e:

    dwelp change two words
    xp change two alphabets

colordiff and vim

Here mention a perl script package on Debian, colordiff. For highlighting output of diff just only pipe the output of diff to colordiff. For example, $ diff -rq /etc /var | colordiff | less -R or other similar commands as $svk diff | colordiff | less -R to get the highlighted. Otherwise we can use vim to got the same effect if syntax on has set in .vimrc. For example, $diff -rq /etc /var | vim -. Just only some difference between them. :p

vim tab 功能

今天逛 Cornelius 時偶然發現 Vim tab 的功能，是 7.0 開始加入的新功能，使用感覺相當方便，基本用法如下：
:tabe filename 在新標籤頁打開一個檔案
:tabc 關閉標籤頁
:tabo 關閉其他標籤頁
:tabn 下一個標籤頁 或是 gt, C-PageDown
:tabp 上一個標籤頁 或是 gT, C-PageUp
:tabr 第一個標籤頁
:tabl 最後一個標籤頁
:tabs 顯示所有標籤頁
:tabm [N] 移動到第N順位
還可以 :set tabline 來定義 tab 顯示方式
