How to visually select based on indentation?

Question

If someone is editing the following javascript file:

let foo = true
if (foo) {
  let bar = 42
  // moooooore code...
}

You can use vi{ anywhere on the line with let bar to select let bar = 42 and all other lines inside {...}.

However, how can I select based on indentation?

Let's take Ruby as an example:

def some_method
  if @foo
    @bar = 42
    # moooooore code...
  end
end

What command would I use to select @bar = 42 and all other code ?

Answer 1

I've used vim-indent-object for a while with some success.

It provides text objects like ii, ai, iI, and aI, each with slightly different semantics.

For your sample code

def some_method
  if @foo
    @bar = 42
    # moooooore code...
  end
end

If the cursor is anywhere inside the if block, you could use vii to select the the bar and more lines. Or, use =ii, cii, dii, !ii, yii &c., depending on what you want to do.
