Automatically convert indentation from 2 to 4 spaces in Sublime Text 3

问题

There are a few topics about auto-conversion of the indentation in Sublime Text, but I didn't find the way to do it automatically.

Many files I download have indentation of 2, which I hate, so I want to convert them to 4. What I do is:

Select Tab size: 2
Convert indentation to Tabs
Select Tab size: 4
Convert indentation to Spaces

I don't think I need to mention that it's too much work for every single file. Some people suggest Reindent option, but for my experience, it almost never works correctly.

Is there some build-it way, or perhaps a package to convert indentation in one step?

回答1:

Converting indentation to a personal preference can be a tedious task in Sublime Text which, as you observe, gets mentioned on StackOverflow quite regularly. In fact 4 years ago I answered a question which lists almost exactly the steps you've listed in your question.

I too have found the 3 Command Pallette reindent commands to be a little temperamental, sometimes working as I think they ought to and sometimes doing (what appears to be) nothing at all. But no matter...

There is of course a way to perform the actions you've listed in one step; use a macro.

Copy and paste the macro code below and save it in your User folder as IndentationTo4Spaces.sublime-macro.

[
    { "command": "set_setting", "args": {"setting": "tab_size", "value": 2} },
    { "command": "unexpand_tabs", "args": {"set_translate_tabs": true} },
    { "command": "set_setting", "args": {"setting": "tab_size", "value": 4} },
    { "command": "expand_tabs", "args": {"set_translate_tabs": true} }
]

You could run the macro from the menu Tools --> Macros --> User --> IndentationTo4Spaces, set up a key binding, or add an entry to the Command Pallette.

// Add keys to: Packages/User/Default (Linux/OSX/Windows).sublime-keymap
{ "keys": ["ctrl+shift+y"], "command": "run_macro_file",
  "args": {"file": "res://Packages/User/IndentationTo4Spaces.sublime-macro"} },

// Add command to: Packages/User/Default.sublime-commands
{ "caption": "Convert Indentation To 4 Spaces", "command": "run_macro_file",
  "args": {"file": "res://Packages/User/IndentationTo4Spaces.sublime-macro"} },
