Learning Vim

3 minute read

In an attempt to familiarize myself with the unfamiliar, I decided to build a fun side-project in Ruby and Vim. Effectively learning a new language, framework, and editor.

Coming from Nano, Quanta, Eclipse PDT, TextMate, Netbeans; I found (Mac/g)Vim is big a step, and first two weeks you should not expect to be productive.

But after some persistence, I'm now faster in Vim than I was in my previous editors. Except for NetBeans still. Maybe that changes as I get better, but having an editor that understands your code is also a powerful thing. Scope-aware refactoring and jumping to declarations make that I keep both NetBeans and Vim around. Cause Vim on the other hand let's you navigate and hack on text like no other.

Investing in a tool like this pays off. For life.

Cause as so long as computers can't read our minds, we're better of maximizing the efficiency of our typing. If your brain has to wait for your hands to transfer the message, you're just throwing away time & creativity flow.

Here are the resources that helped me get started with Vim.
