sideways.vim : Move function arguments (and other delimited-by-something items) left and right

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.

It also works for multiline lists. Try experimenting with this example:

    <div class="example"
         style="color: red;"

Apart from functions, it works for a lot of other things, but it's recommended to look at the github project or the help files for additional details. The plugin also provides:

- A text object to change/delete/yank items in lists
- A mapping to add new items forwards or backwards in the list
install details
The easiest way to install the plugin is with a plugin manager:

- vim-plug: https://github.com/junegunn/vim-plug
- Vundle:   https://github.com/VundleVim/Vundle.vim

If you use one, just follow the instructions in its documentation.

You can install the plugin yourself using Vim's |packages| functionality by cloning the project (or adding it as a submodule) under `~/.vim/pack/<any-name>/start/`. For example:

    git clone https://github.com/AndrewRadev/sideways.vim ~/.vim/pack/_/start/sideways

This should automatically load the plugin for you on Vim start. Alternatively, you can add it to `~/.vim/pack/<any-name>/opt/` instead and load it in your .vimrc manually with:

    packadd sideways

If you'd rather not use git, you can download the files from this page and unzip them in the relevant directory.
