什么是快速的方式来评论/取消注释行在Vim？ [英] What's a quick way to comment/uncomment lines in Vim?

问题描述

我有一个在vi中打开的Ruby代码文件，有＃注释掉的行：

I have a Ruby code file open in vi, there are lines commented out with #:

class Search < ActiveRecord::Migration
  def self.up
    # create_table :searches do |t|
    #   t.integer :user_id
    #   t.string :name
    #   t.string :all_of
    #   t.string :any_of
    #   t.string :none_of
    #   t.string :exact_phrase
    # 
    #   t.timestamps
    # end
  end

  def self.down
    # drop_table :searches
  end
end

假设我要取消注释所有第 def ... end 节中的行。在Vim中这是一个有效的方法是什么？

Say I want to uncomment all the lines in the first def ... end section. What's an efficient way to do that in Vim?

一般来说，我在寻找一个简单而流畅的方式来评论和取消注释行。这里我处理Ruby代码，但它可以是JavaScript（ // ）或Haml（ - ＃） 。

In general, I'm looking for an easy and fluid way to comment and uncomment lines. Here I'm dealing with Ruby code, but it could be JavaScript (//) or Haml (-#).

推荐答案

对于这些任务，我大部分时间使用块选择。

For those tasks I use most of the time block selection.

将光标置于第一个＃字符，请按 Ctrl V （或 Ctrl Q for gVim）最后一条注释行，然后按 x ，将垂直删除所有＃字符。

Put your cursor on the first # character, press CtrlV (or CtrlQ for gVim), and go down until the last commented line and press x, that will delete all the # characters vertically.

对注释一个文本块几乎是一样的：首先，转到要注释的第一行，按 Ctrl V ，然后选择直到最后一行。其次，按 Shift I ＃ Esc （然后再给它一个） c $ c>＃字符。对于默认情况下附带debian / ubuntu的vim的精简版本，请改为在第二步中键入：s / ^ /＃。

For commenting a block of text is almost the same: First, go to the first line you want to comment, press CtrlV, and select until the last line. Second, press ShiftI#Esc (then give it a second), and it will insert a # character on all selected lines. For the stripped-down version of vim shipped with debian/ubuntu by default, type : s/^/# in the second step instead.
