Note to self
I use nano to do quick edits or test out ideas in a dirty and quick script. If you use python, it's a good idea to have proper indentaion. Nano has a default tab size of 8.
set tabsize 4 set tabstospaces
If you have a file and want to conver tabs to spaces, quick one liner:
expand -4 tabbed.py > spaced.py
Now, if you want to work with a different tab size- lets say you want to edit a two space JS file, but don't want to change the default:
nano -T 2 Gruntfile.js
