This is a mirror of

Github project:

The plugin defines two commands, ":SidewaysLeft" and ":SidewaysRight", which move the item under the cursor left or right, where an "item" is defined by a delimiter. As an example:

    def function(one, two, three):

Placing the cursor on "two" and executing `:SidewaysLeft`, the "one" and "two" arguments will switch their places, resulting in this:

    def function(two, one, three):

In this case, the delimiter is a comma. The plugin currently works with various other cases and it's intended to make the process configurable. While this particular example is in python, this should work for arguments in many different languages that use round braces to denote function calls.

For ruby and eruby, it detects method calls without braces as well:

    link_to user_registration_path, 'Something'
    # changes to:
    link_to 'Something', user_registration_path

Apart from functions, it works for square-bracket lists in dynamic languages:

    list = [one, [two, four, five], three]

Notice that, if you experiment with this example, you'll find that you can move the entire second list around. The plugin takes into consideration nested structures.

Apart from functions, it works for lists in CSS declarations:

    border-radius: 20px 0 0 20px;

And, it also works for cucumber tables (see docs for better table formatting):

      | input_1 | input_2 | button | output |
      | 20      | 30      | add    | 50     |
      | 2       | 5       | add    | 7      |
      | 0       | 40      | add    | 40     |

It's highly suggested to map the two commands to convenient keys. For example, mapping them to <c-h> and <c-l> would look like this:

    nnoremap <c-h> :SidewaysLeft<cr>
    nnoremap <c-l> :SidewaysRight<cr>

The plugin is intended to be customizable, though at this point you'd need to look at the source to do this.
