使用VIM查看同一文件时，Emacs缩进不起作用

Question

I'm having a problem with indentation in Emacs.

Whenever I'm indenting code in Emacs it looks fine, but when I look at the same code in VIM/Github/Eclipse, there's parts of code that isn't indented.

Examples:

This is what I see in Emacs:

public class Test {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

This is what I see in the other editors:

public class Test {
    public static void main(String[] args) {
    System.out.println("Hello, World!");
    }
}

The languages I'm seeing this in is: - C - Java - JavaScript

I haven't tried to simulate the behaviour in other languages atm...

I'm also seeing these symptoms in some of the code I receive from some of my teachers that I know use Emacs to generate pre-code that I'll be looking at in Eclipse/VIM/Github.

One extra thing: using 'cat' on linux displays indentation, made by Emacs, correct! It's the only thing besides Emacs that can do that....

Is there any way to prevent this? It isn't a big problem, but VERY irritating atm and I haven't been able to come up with a solution.

This is very likely a tabs vs. spaces issue. Emacs is probably displaying the tabs as eight spaces as this is the standard that cat would use.

Run :set list in vim to see what characters are making up the whitespace. If you want the indentation show up the same you either need to configure all the editors to use the same indentation (preferable) or configure them to at least show tabs as the same number of spaces.

Relevant vim settings: expandtab , tabstop .
Relevant emacs settings: tab-width , indent-tabs-mode .
