Delete everything between two brackets in Vim, including newlines

问题

Say I have the following python array literal:

def f():
    arr = [
        1,          
        2,
        3   
    ]  

I want to delete everything in the brackets so that it becomes this:

def f():
    arr = [] 

How can I do that with minimal commands in vim?

---

These are some of my attempts:

• Using di] will delete the text, but not the empty newlines, leaving a lot of whitespace I'd have to delete:

  def f():
      arr = [         
      ]
  

• Using da] will delete the newlines, but also the brackets:

  def f():
      arr =
  

回答1:

You can simply do:

ca[[]<Esc>

or:

ca][]<Esc>

See :help text-objects.

回答2:

With your cursor on the first opening bracket ([), press V, followed by %. This will select the block which you then can join J, followed by di[.

回答3:

Select the lines in visual mode (v) and use J to remove newlines. Then use di[.

Or if there are many lines, di[ first, after which you move the cursor to top line and then J. This will potentially leave a space between the brackets which has to be removed with x.

I find using a code formatter shortcut saves a lot of time

If you install vim prettier, you could do di[ <leader>p

Using the formatter in JS for example means I don't have to remove extra spacing, jump to end of line to insert ;, or fix indenting etc
