VIM TIP
if you are an avid Vim user and use it extensively, here is a small tip. You can’t use the following two settings at the same time:
• expandtab (replaces tabs with spaces - needed for easier YAML editing)
• paste (pastes text without trying to modify it / interpret it. You almost always want this when you copy text into Vim)
so if you are editing YAML files, make sure to:
:set nopaste
before editing it you have paste set in your ~/.vimrc
this is actually a common mistake and I found that even the lab environment for this course does this (they have both expandtab + paste set so if you use <TAB>s, it does not convert them to spaces)
