                            end
--------------------------------------

and same as module, class, while and so on.

In vim filetype, function, if, while ... rules are available. And also you can use in sh (zsh) such as if, case.

CUSTOMIZATION

lexima.vim provides highly customizable interface. You can define your own rule by using lexima#add_rule().

" Please add below in your vimrc
call lexima#add_rule({'char': '$', 'input_after': '$', 'filetype': 'latex'})
call lexima#add_rule({'char': '$', 'at': '\%#\$', 'leave': 1, 'filetype': 'latex'})
call lexima#add_rule({'char': '<BS>', 'at': '\$\%#\$', 'delete': 1, 'filetype': 'latex'})

You will get

Before  Input   After
---------------------
|       $       $|$
---------------------
$|$     $       $$|
---------------------
$|$     <BS>    |
---------------------

These rules are enabled at only latex filetype. For more information, please see :help lexima-customization

DOT REPEATABLE

If you type foo("bar, you get

foo("bar")

and once you type 0., you finally get

foo("bar")foo("bar")
