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#toggle()` command, the argument list will be wrapped to one per line. ``` -Foo('wibble', 'wobble', 'wubble') +Foo(wibble, wobble, wubble) ``` @@ -39,9 +66,9 @@ Becomes this: ``` Foo( - 'wibble', - 'wobble', - 'wubble' + wibble, + wobble, + wubble ) ``` @@ -49,42 +76,42 @@ Foo( List definitions work in a similar fashion: ``` -foo = ['bar', 'baz', 'qux', 'quux', 'corge'] +foo = [bar, baz, qux, quux, corge] ``` Becomes this: ``` foo = [ - 'bar', - 'baz', - 'qux', - 'quux', - 'corge' + bar, + baz, + qux, + quux, + corge ] ``` -Dictionaries work just fine too: +Dictionaries also work the way you expected them to: ``` -foo = {'bar': 1, 'baz': 3, 'qux': 3, 'quux': 7} +foo = {bar: 1, baz: 3, qux: 3, quux: 7} ``` Becomes this: ``` foo = { - 'bar': 1, - 'baz': 3, - 'qux': 3, - 'quux': 7 + 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]}) +Foo([wibble, wobble, wubble], spam, {bar: baz, qux: [1, 3, 3, 7]}) ``` Becomes this: @@ -92,28 +119,28 @@ Becomes this: ``` Foo( - ['wibble', 'wobble', 'wubble'], - 'spam', - {'bar': 'baz', 'qux': [1, 3, 3, 7]} + [wibble, wobble, wubble], + spam, + {bar: baz, qux: [1, 3, 3, 7]} ) ``` -You can continue expanding to: +You can continue argument expansion to: ``` Foo( [ - 'wibble', - 'wobble', - 'wubble' + wibble, + wobble, + wubble ], - 'spam', + spam, { - 'bar': 'baz', - 'qux': [ + bar: baz, + qux: [ 1, 3, 3,
