Vim and Emacs


After watching the Bloomerg video of Mr Torvalds, I found that he is using Emacs-like editor, which is uemacs, I immediately compiled my Vim and Emacs cheatsheet.

A programmer can write program without IDE, but cannot write without a good text editor. There are a lot of modern text editors. But I feel that learning using a text user interface (console-based) text is very much important. Imagine that you have to use SSH to write some scripts on the remote computer.

I personally inclined to Vim. This is because of Vi editor, which is a very common text editor in every Unix-like OS. Therefore, I learnt Vim.

Unlike Vim, Emacs does not have the visual mode or insert mode. Therefore, Emacs is easier to highlight/select the text.

The following is the comparison table (my personal cheatsheet),
