如何强制Sublime Text每个标签缩进两个空格？

本文翻译自：How do I force Sublime Text to indent two spaces per tab?

Is there a way to force Sublime Text 2 to always indent two spaces per tab when working with Ruby files? 有没有办法强制Sublime Text 2在使用Ruby文件时始终每个标签缩进两个空格？

I know that indentation can be set under the view -> indentation menu option, but it does not stick. 我知道缩进可以在view -> indentation菜单选项下设置，但它不会粘。 Every time I open a new file and hit tab, it reverts back to four spaces. 每次我打开一个新文件并点击标签时，它都会恢复为四个空格。

If you want to force your chosen tab setting, ignoring what's likely already going on in the file, then you should include detect_indentation in your configuration (your User settings or your Syntax Specific settings, depending on if you want it global or per-filetype): 如果您想强制选择的选项卡设置，忽略文件中可能已经发生的事情，那么您应该在配置中包含detect_indentation （您的用户设置或语法特定设置，具体取决于您是希望全局还是每个文件类型） ：

{
    "tab_size": 2,
    "translate_tabs_to_spaces": true,
    "detect_indentation": false
}

You can also do this with the text link in the bottom bar of Sublime Text 2 ( On the right side ) that says "Tab Size 4" by default, click that and a window comes up with options to set the tab size from 1 space all the way up to 8 spaces and includes options to convert tabs to spaces and spaces to tabs. 您也可以使用Sublime Text 2（右侧）底栏中默认显示“Tab Size 4”的文本链接，单击该文本链接，然后在窗口中显示从1个空格设置选项卡大小的选项一直到8个空格，包括将标签转换为空格和空格到标签的选项。

Looks like this: 看起来像这样：

Can I suggest EditorConfig ? 我可以推荐EditorConfig吗？ There is an extension to autoload and apply the .editorconfig file. 自动加载有一个扩展并应用.editorconfig文件。 Then just create one in the root of your project. 然后只需在项目的根目录中创建一个。

.editorconfig

[*.rb]
indent_style = tab
indent_size = 2

This way, your settings are project-specific and file-specific if you use different styles for each project or language. 这样，如果为每个项目或语言使用不同的样式，则您的设置是特定于项目和特定于文件的。

Here is what my own .editorconfig looks like. 这是我自己的.editorconfig看起来像。

# editorconfig.org
root = true

[*]
indent_style = space
indent_size = 2
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

I followed the previous answers, including adding the detect_indentation line, and my tabs were still five spaces. 我按照之前的答案，包括添加detect_indentation行，我的标签仍然是五个空格。 Then I realized that selecting Preferences -> Settings -> More -> Syntax Specific -> User from a ruby file was opening up Ruby on Rails.sublime-settings for me, not Ruby.sublime-settings . 然后我意识到从ruby文件中选择Preferences -> Settings -> More -> Syntax Specific -> User为我打开了Ruby on Rails.sublime-settings ，而不是Ruby.sublime-settings 。

I renamed my Ruby on Rails.sublime-settings file to Ruby.sublime-settings . 我将Ruby on Rails.sublime-settings文件重命名为Ruby.sublime-settings 。 Finally two-space tabs worked! 最后两个空格标签工作！ I went ahead and put the same settings in Ruby on Rails.sublime-settings as well, just to be sure. 我继续在Ruby on Rails.sublime-settings相同的设置，只是为了确定。

I use Stupid Indent package. 我使用Stupid Indent包。

Install Package -> Stupid Indent Install Package - > Stupid Indent

Preferences -> Package Settings -> Stupid Indent -> Setting-Users Preferences - > Package Settings - > Stupid Indent - > Setting-Users

Copy settings (of Ruby part) into. 将设置（ Ruby部分）复制到。

{
    "configuration":
    [
        {
            "patterns": ["*.rb"],
            "tab_size": 2,
            "translate_tabs_to_spaces": true
        }
    ]
}
