Configuring IdeaVim to be awesome

Why do I feel this is important?

Do you really know how good you can make IntelliJ using vim bindings and the IdeaVim plugin? It took me quite a long time before I understood what it actually was capable of.

I really enjoy NeoVim, but being mainly a Java developer it still cannot beat IntelliJ in my opinion. Although I do miss the fact that the terminal is a buffer in NeoVim.

At first, I was using IdeaVim only for vim motions, which is great by itself, but then I started to understand how to configure it to be even better.

Adding actions to `.ideavimrc`

You might already know that IdeaVim reads its configurations from ~/.ideavimrc.

Adding IDE actions here can be done as follows:

" Variant 1
nmap <Leader>rn <action>(RenameElement)

" Variant 2
nmap <leader>rn :action RenameElement<CR>

To reload the configuration, you can run the following vim command:

:source ~/.ideavimrc

Finding actions

The basic way to search for actions is done from the IDE itself.

" List all found actions
:actionlist

" Filter the action list
:actionlist git

Alternatively you can browse for actions. Here's a link to a collection of IntelliJ actions.

Also, adding plugins to your IDE adds new actions, that you can then map in you .ideavimrc. They can then be found with the :actionlist command.

My own `.ideavimrc`

There are some pain points, but for the most part I can do everything that I need for my daily development without touching the mouse.

I hope this is either enlightening or inspiring.
