ARGWRAP                                                                                                  *argwrap-argwrap*

ArgWrap is an industrial strength argument wrapping and unwrapping extension for the Vim text editor. It can be used for
collapsing and expanding everything from function calls to array and dictionary definitions.  All operations are easily
reversible and correctly preserve the indentation of the surrounding code.

INSTALLATION                                                                                        *argwrap-installation*

1.  Clone or otherwise download ArgWrap extension. Users of pathogen.vim (https://github.com/tpope/vim-pathogen) can
    clone the repository directly to their bundle directory:
>
        $ git clone https://github.com/FooSoft/vim-argwrap ~/.vim/bundle/vim-argwrap
<
2.  Create a keyboard binding for the `ArgWrap` command inside your `~/.vimrc` file.
    For example, to declare a normal mode mapping, add the following command:
>
        nmap <silent> <leader>a <Plug>(ArgWrapToggle)
<

CONFIGURATION                                                                                      *argwrap-configuration*

You can customize the behavior of this extension by setting values for any of the following optional buffer and
global configuration variables in your `.vimrc` file. Buffer variables (prefixed with `b:`) take precedence over
global variables (prefixed with `g:`), making them ideal for configuring the behavior of this extension on a file by
file basis using `ftplugin` or `autocmd`. For example, the `argwrap_tail_comma` variable has two variants declared as
`b:argwrap_tail_comma` and `g:argwrap_tail_comma`, for buffer and global scopes respectively.

HOOKS                                                                                                      *argwrap-hooks*

It is possible to hook before or after a  wrap/unwrap operation using
autoloaded functions, the hooks are named:
    - `pre_wrap`
    - `pre_unwrap`
    - `post_wrap`
    - `post_unwrap`

For example to do something after any wrap create a function: >
    argwrap#hooks#my_hook#post_wrap(range, container, arguments)
<
It is also possible to create a hook for a specific filetype: >
    argwrap#hooks#filetype#vim#my_hook#post_wrap(range, container, arguments)
<

Global hooks are loaded on the first time a wrap/unwrap operation is done.
Filetype hooks however are only loaded for the current filetype.
You can see the list of loaded hooks with: >
    echo g:argwrap_global_hooks
    echo g:argwrap_filetype_hooks
    echo b:argwrap_hooks
<
The hooks are loaded from any directory specified in the |runtimepath|.
Global hooks will be executed before filetype ones.
Global and filetype hooks are sorted by the |globpath()| function. Meaning you
can control the execution order of the hooks by prefixing them with a
priority.


An important things to know when writing a new hook is that calling an
|autoload| function which does not exist will source the file that should
contain the function every time.
So even if you do not need one of the hook, always define them all. This is a
template you can use to get started: >
    function! argwrap#hooks#my_hook#pre_wrap(range, container, arguments) abort " {{{
      " Do nothing but prevent the file to be loaded more than once
      " When calling an autoload function that is not define the script that
      " should contain it is sourced every time the function is called
    endfunction  " }}}

    function! argwrap#hooks#my_hook#pre_unwrap(range, container, arguments) abort " {{{
      " Do nothing but prevent the file to be loaded more than once
      " When calling an autoload function that is not define the script that
      " should contain it is sourced every time the function is called
    endfunction  " }}}

    function! argwrap#hooks#my_hook#post_wrap(range, container, arguments) abort " {{{
      " Do nothing but prevent the file to be loaded more than once
      " When calling an autoload function that is not define the script that
      " should contain it is sourced every time the function is called
    endfunction  " }}}

    function! argwrap#hooks#my_hook#post_unwrap(range, container, arguments) abort " {{{
      " Do nothing but prevent the file to be loaded more than once
      " When calling an autoload function that is not define the script that
      " should contain it is sourced every time the function is called
    endfunction  " }}}

USAGE                                                                                                      *argwrap-usage*

1.  Position the cursor inside of the scope of the parenthesis, brackets or curly braces you wish to wrap/unwrap (not
    on top, before or after them).
2.  Execute the keyboard binding you defined above to toggle the wrapping and unwrapping of arguments.
