vim-extract-variable
Extract an expression to a variable.
Installation
Use one of the hundred of methods that exist to install a vim plugin. I recommend vim-plug:
Plug 'fvictorio/vim-extract-variable'
Usage
A normal and visual mapping is set: <leader>ev. If you use it in visual mode, it extracts the selected text to a variable. The name of the variable will be prompted to you. If you use it in normal mode, the text between parentheses is used.
The declaration is created in the previous line, using O, so it should preserve the indentation if you have autoindent on.
