Tab character width setting

In source editor, tab character width is 8 characters long. Since WebKit supports tab-size CSS property (https://bugs.webkit.org/show_bug.cgi?id=52994), it would be nice to make tab character width configurable.

@Nikita, do you have a patch for this?

No, but I can make one if think it’s a valuable feature.

I think it would be useful.

I’m not sure about TextIndent class I introduced.

Indentation size and tab size can have different values. Indentation size is a "model" property, it affects the file being saved on disk. Tab size is "view" property, it only affects visual representation. I'd suggest that you add a selector for the tab size and use it in the TextEditor.js only. The model part of the code should stay the same.

I don't think you need this, but if you did, you would need to format it as:

/**
 * @constructor
 */
WebInspector.TextEditorModel.Indent = function()
{
}

Why would someone want a tab size different from an indentation size? I’ve attached a screenshot of indentation settings in Sublime Text 2; it doesn’t distinguish indentation size and tab size.

Well, all the other editors I know distinguish between the two and it makes sense to me. As I explained above, one is about model and another is about view. Imagine the code guidelines where indentation is done using 4 spaces, while tab character is still allowed and should be 8 characters long. Or indentation is two tabs.

I see IDEs such as Xcode and IntelliJ IDEA do distinguish the two. Many lightweight code editors such as Chocolat.app and Textmate don’t.

Personally, I just want to make a tab character 4 spaces width. It’s a default tab width in all the editors I’ve mentioned above.

I suggest to make this small change for now. If someone actually want to configure the Tab size, we’ll see the bug filled.
