Vim

Vim is a text editor based into keyboard shortcuts and modes. It has a stepper learning curve but, once you learn it enables very fast shortcuts for most common uses. It took me a couple hours to get used with most of the basics commands. It does provide a very fast way to perform all the common typing operations. You can customize as much you want with plugins and vim programming language. If you start to use, be certain: you will never stop to learn new features. This post is just a collection of some of cool features thay I learned. If want learn more check Vim Wikia.

First things first - How to close

Yeah! The first major obstacle is the two most basic things edit and quit.

• Force Quit: Press ESC then type :q!
• Save File and Quit: Press ESC then type :x!

Insert Text from file at Cursor position

It very stratfoward just type

:r secretSauce.txt

Open Several Files from terminal

$ vim -p *.md

Search and Replace - AKA Vim Regex

Probably the thing that I use most is its search powered by Regex. The sintax is very similar to sed witch is also a Regex based editor.

:%s/badWord/goodWord/g

Grouping

Group are one the coolest features from regex. It enables using part of maching search expression as argument for replacement. In other worlds, you can change any expression for a fix format, ensure a default format, add things between worlds.

Changing Case

Ensure only First Letter with Upper Case for each world.

:%s/\([a-z]\)\([a-zA-Z]*\)/\U\1\L/gc

Change from dash separated words (aaa_bbb) to cammelCase (aaaBbb)

:%s/([a-za-z]*\)_/\([a-z]\)\([a-z]*_\)\L\1\U\2\L3/gc
