Sublime text: Swap line and indent

Question

I recently gave atom a try. Despite being too slow, there was one thing I liked: the way auto indent worked, basically everywhere.

I found here how to make Paste + Indent the default in sublime text.

But I'd also like that the:

{ "keys": ["ctrl+shift+up"], "command": "swap_line_up" },
{ "keys": ["ctrl+shift+down"], "command": "swap_line_down" },

become swap_line_up_and_indent so that if I have:

console.log('hello');
function() {

}

and I ctrl+shift+down, I get:

function() {
  console.log('hello'); // indented yai!!
}

Any chance?

So, the easiest way to do this (aside from writing a rather extensive plugin) is by macro. Here is swap_line_down_and_indent.sublime-macro:

[
    {
        "command": "swap_line_down"
    },
    {
        "command": "indent"
    }
]

and swap_line_up_and_indent.sublime-macro:

[
    {
        "command": "swap_line_up"
    },
    {
        "command": "move",
        "args":
        {
            "by": "lines",
            "forward": true
        }
    },
    {
        "command": "indent"
    }
]

Save the files in Packages/User where Packages is the folder opened when selecting Preferences → Browse Packages…. Next, edit your custom keymap with the following:

{ 
    "keys": ["ctrl+shift+up"], 
    "command": "run_macro_file", 
    "args": 
    {
        "file": "res://Packages/User/swap_line_up_and_indent.sublime-macro"
    } 
},
{ 
    "keys": ["ctrl+shift+down"], 
    "command": "run_macro_file", 
    "args": 
    {
        "file": "res://Packages/User/swap_line_down_and_indent.sublime-macro"
    } 
}

and you should be all set. There are a couple caveats, though. These macros will only indent one level, so you may need to use Ctrl] to indent the line further. Also, it is assumed that the line to be indented is the lower line after the swap_line_[up|down] command is run.

You can do this as well by using the 'Chain of Command' package. Install the package and just add the following to the user key bindings file:

{
   "keys": ["ctrl+super+up"], 
   "command": "chain", 
   "args": {
     "commands": [
       ["swap_line_up"],
       ["reindent", {"single_line": false}]
     ],
   },
 },
{
  "keys": ["ctrl+super+down"], 
  "command": "chain", 
  "args": {
    "commands": [
      ["swap_line_down"],
      ["reindent", {"single_line": false}]
    ],
  },
}
