I really don’t know why Apple doesn’t do the similar things like other Linux distribution makers. The default vim is very simple–many setups are not switched on. For example: “syntax color”, and “ruler”.
For mac users, just edit .vimrc at HOME, add two lines:
set syntax enable
Your vim will show syntax color when you are working on some program codes and the right bottom corner will show the current position. Then, I don’t need to run “set nu” to see what’s the number of the current line I am..
Better mode, syntax is colored and the ruler is shown!
