swapit.vim is a vim plugin designed to make repetitive changes easier.

On a current word that is a member of a swap list use the
incrementor/decrementor keys (:he ctrl-a,ctrl-x). The script
will cycle through a list of related options.

The idea is to compile a list of common property swaps for various languages/frameworks

NOTE: This has been done before in a simpler vimscript#1676 script. This script differs in it’s ability to handle phrase swapping eg ‘int’ to ‘unsigned int’

eg. 1. Boolean

foo=true

in normal mode, pressing ctrl-a on the t will make it

foo=false

eg. 2. Multi Word Swaps.

Hello World! is a test multi word swap.

on ‘Hello World!’ go select in visual (vi’) to get

‘GoodBye Cruel World!’

eg 3. Defining custom swaps

A custom list is defined as follows.

:SwapList datatypes bool char int float double

The first argument is the list name and following args
are members of the list.

if there is no match then the regular incrementor decrementor
function will work on numbers

At the bottom of the script I’ve added some generic stuff but

You can create a custom swap file for file types at

~/.vim/after/ftplugins/swapit.vim
with custom execs eg.
exec "SwapList functionscope private protected public"

For this alpha version multi word swap list is a bit trickier
to to define. You can add to the swap list directly using
vimscript within a after/ftplugin/_swap.vim file

call extend(g:swap_lists, [{’name’:‘Multi Word Example’,
\‘options’: [‘swap with spaces’,
\‘swap with #$# chars in it’ ,
\‘running out of ideas here…’]}])

Future versions will make this cleaner with a :Command

Also if you have a spur of the moment Idea type
:SwapIdea
To get to the current filetypes swapit file

Note: This alpha version doesnt create the directory structure

To integrate with other incrementor scripts (such as
speeddating.vim vimscript #2120 or monday.vim vimscript #1046),
:nmap SwapItFallbackIncrement and SwapItFallbackDecrement
to the keys that should be invoked when swapit doesn’t have a
proper option. For example for speeddating.vim:

nmap SwapItFallbackIncrement SpeedDatingUp
nmap SwapItFallbackDecrement SpeedDatingDown

install details
place swapit.vim in plugins directory

(for extending to filetypes)
mkdir ~/.vim/after/ftplugin/
