Swapping of text in Vim

A plugin which makes swapping of text in Vim easier

1. Visual mode

1.1 \x

First select some text ([] represents the highlighted area). Then press \x

[a ==   123] [  a == 123 ] [a==123]
      |            |           |
      V            V           V
123 ==   a     123 == a    123==a

Note: Your selection can be loose and include white spaces at both ends.

1.2 \cx

By default the plugin acts on comparison operators
You are however allowed to specify any pivot for the swapping.

First select some text. Then press \cx
You will be asked to give a pattern (% used here)

Just testing  %  a percentage as a pivot
                  |
                  V
a percentage as a pivot  %  Just testing

1.3 Multiple lines

You can also use V, v or ^v to select several lines (v used), then press \x

a == [123
user !~ unknown
0]!=#1
   |
   V
123 == a
unknown !~ user
1!=#0

2. Normal mode

Swap with WORD on the right \x

# indicates the cursor position in the examples below.

      #
zero one      a_longer_word three
         |
         V
zero a_longer_word      one three

Swap with WORD on the left \X

zero one two     three
let's have some more fun
  #      |
         V
zero one two     let's
three have some more fun

2.1 Repeat

This plugin integrates with Tim Pope's repeat plugin. It means that you can
use . (dot) to repeat any normal mode (for now) swap mapping you just used!

3. Supported operators

Comparison operators

===    !==     <>    ==#    !=#     >#
>=#     <#    <=#    =~#    !~#    ==?
!=?     >?    >=?     <?    <=?    =~?
!~?     ==     !=     >=     =~     <=
!~      ~=

Logical operators
&& ||

Assignment operators

+=     -=     *=     /=     %=     &=
|=     ^=    <<=    >>=

Scope operators
::

Pointer operators
->* -> .*

Bitwise operators
<< >>

Misc operators

>      <       =      +      -      *
/      %       &      |      ^      .
?      :       ,     '=     '<     '>
!<     !>

3.1 Custom operators

You can define your own operators by putting a similar line in your vimrc:

let g:swap_custom_ops = ['first_operator', 'second_operator', ...]

4. Custom mappings

You have the possibility to define your own custom mappings in your vimrc:

vmap <leader>x         <plug>SwapSwapOperands
vmap <leader><leader>x <plug>SwapSwapPivotOperands
nmap <leader>x         <plug>SwapSwapWithR_WORD
nmap <leader>X         <plug>SwapSwapWithL_WORD

Note: You can replace \x, \cx, \X with whatever you like.
