如何在Ruby的IRB中启用自动完成

When I use Merb's built in console, I get tab auto-completion similar to a standard bash prompt. I find this useful and would like to enable it in non-merb IRB sessions. How do I get auto-completion in IRB?

当我使用Merb的内置控制台时，我将获得类似于标准bash提示符的tab自动完成。我发现这很有用，并希望在非merb IRB会话中启用它。如何在IRB中自动完成?

3 个解决方案

#1

Just drop require 'irb/completion' in your irbrc.

在你的irbrc中只需要“irb/完成”。

If that doesn't work try bond, http://tagaholic.me/bond/:

如果这行不通，可以试试bond, http://tagaholic.me/bond/:

   require 'bond'; require 'bond/completion'

Bond not only improves irb's completion, http://tagaholic.me/2009/07/22/better-irb-completion-with-bond.html, but also offers an easy dsl for making custom autocompletions.

邦德不仅提高了irb的完成度，http://tagaholic.me/2009/07/22/better irb- completionwith- Bond。它还提供了一个简单的dsl，用于定制自动完成。

This is just repeating the information on Cody Caughlan's comment above so it is easier to find:

这只是重复Cody Caughlan的评论，这样更容易找到:

either require 'irb/completion' or add the following to ~/.irbrc

要么要求“irb/completion”，要么向irbrc添加以下内容

IRB.conf[:AUTO_INDENT] = true
IRB.conf[:USE_READLINE] = true
IRB.conf[:LOAD_MODULES] = [] unless IRB.conf.key?(:LOAD_MODULES)
unless IRB.conf[:LOAD_MODULES].include?('irb/completion')
  IRB.conf[:LOAD_MODULES] << 'irb/completion'
end

This is what worked for me on Mac OS 10.11.5. using rvm. Do the following :

这就是我在Mac OS 10.11.5中的表现。使用区。执行以下操作:

sudo gem install bond
sudo gem安装债券
Create the file .irbrc in your home directory. vi ~/.irbrc
在主目录中创建文件。irbrc。六世~ / .irbrc
Add the following lines in the .irbrc file require 'bond' Bond.start

在.irbrc文件中添加以下行需要'bond' .start
Save and close the file

保存并关闭文件
Open irb and use tab key to autocomplete
打开irb并使用tab键自动完成
