FunctionTextObj (IdeaVim extension)

An extension for IdeaVim that adds text objects for manipulating functions/methods in your code. Similar to how iw operates on words or i" operates on quoted strings, this plugin provides if and af to operate on functions.

Features

• if - "inner function" - selects the function body (excluding braces)
• af - "around function" - selects the entire function (including braces and signature)

These text objects work with all Vim operators and in visual mode:

dif  - delete the function body
caf  - change the entire function
vif  - visually select the function body
yaf  - yank (copy) the entire function
