ABOUT *argwrap-about*
|
|
|
|
argwrap.vim 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. The online resources
|
|
listed below can be accessed to download new versions of this extension and to
|
|
access other information.

================================================================================
|
|
INSTALLATION *argwrap-installation*
|
|
|
|
1. Clone or otherwise download the latest version of the argwrap.vim extension
|
|
from its GitHub page (the script is also available for download through
|
|
vim.org. If you are using pathogen.vim for plugin management (you should)
|
|
you can clone the repository directly to your 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:
|
|
|
|
nnoremap <silent> <leader>a :ArgWrap<CR>
|
|
|
|
3. You can customize the wrapping/unwrapping behavior of this extension by
|
|
setting values for any of the following optional buffer and global
|
|
variables in your .vimrc file:
|
|
|
|
* g:argwrap_wrap_closing_brace or b:argwrap_wrap_closing_brace
|
|
|
|
Specifies if the closing brace should be wrapped to a new line. This
|
|
setting is helpful when working with languages such as Google's Go,
|
|
which enforce coding style during compliation.
|
|
|
|
Brace wrapping enabled (default)
|
|
|
|
```
|
|
Foo(
|
|
wibble,
|
|
wobble,
|
|
wubble
|
|
)
|
|
```
|
|
|
|
Brace wrapping disabled (let g:argwrap_wrap_closing_brace = 0)
|
|
|
|
```
|
|
Foo(
|
|
wibble,
|
|
wobble,
|
|
wubble)
|
|
```
|
|
|
|
* g:argwrap_padded_braces or b:argwrap_padded_braces
|
|
|
|
Specifies which brace types should be padded on the inside with spaces:
|
|
|
|
'': do not add padding for any braces (empty string):
|
|
|
|
[1, 2, 3]
|
|
{1, 2, 3}
|
|
|
|
'[': padding for square braces only (curly braces are not padded):
|
|
|
|
[ 1, 2, 3 ]
|
|
{1, 2, 3}
|
|
|
|
Padding can be specified for multiple brace types as follows:
|
|
|
|
let g:argwrap_padded_braces = '[{'
|
|

|
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.
|
|
|

|
EXAMPLES *argwrap-examples*
|
|
|
|
Below are some examples of common use cases demonstrating the capabilities of
|
|
argwrap.vim. Note that the extension functions identically regardless if it is
|
|
being applied to a function call, list or dictionary definition.
|
|
|
|
Let's begin with a simple function invocation. When there are many arguments
|
|
being passed to the function, we often wish to wrap them to improve code
|
|
readability. If you position your cursor anywhere between the parenthesis and
|
|
execute the ArgWrap command, the argument list will be wrapped to one per line.
|
|
|
|
Foo(wibble, wobble, wubble)
|
|
|
|
Becomes this:
|
|
|
|
Foo(
|
|
wibble,
|
|
wobble,
|
|
wubble
|
|
)
|
|
|
|
List definitions work in a similar fashion:
|
|
|
|
foo = [bar, baz, qux, quux, corge]
|
|
|
|
Becomes this:
|
|
|
|
foo = [
|
|
bar,
|
|
baz,
|
|
qux,
|
|
quux,
|
|
corge
|
|
]
|
|
|
|
Dictionaries also work the way you expected them to:
|
|
|
|
foo = {bar: 1, baz: 3, qux: 3, quux: 7}
|
|
|
|
Becomes this:
|
|
|
|
foo = {
|
|
bar: 1,
|
|
baz: 3,
|
|
qux: 3,
|
|
quux: 7
|
|
}
|
|
|
|
Finally, nested combinations of all the above are also supported:
|
|
|
|
Foo([wibble, wobble, wubble], spam, {bar: baz, qux: [1, 3, 3, 7]})
|
|
|
|
Becomes this:
|
|
|
|
Foo(
|
|
[wibble, wobble, wubble],
|
|
spam,
|
|
{bar: baz, qux: [1, 3, 3, 7]}
|
|
)
|
|
|
|
You can continue argument expansion to:
|
|
|
|
Foo(
|
|
[
|
|
wibble,
|
|
wobble,
|
|
wubble
|
|
],
|
|
spam,
|
|
{
|
|
bar: baz,
|
|
qux: [
|
|
1,
|
|
3,
|
|
3,
|
|
7
|
|
]
|
|
}
|
|
)
|
|
|
|
The argument wrapping and unwrapping operations demonstrated above are easily
|
|
reversible and correctly preserve the indentation of the surrounding code. This
|
|
extension has been tested to work in scenarios of various complexity, but if you
|
|
discover a problem don't hesitate to report it.
