Current Status 80% iOS app, 20% Ruby/Rails
Scenario
I'm looking for a text editor..
1. launch quickly 2. easy to navigate between files 3. and pretty syntax highlight
Vim
Vim = Vi iMproved
Free and Charity
What's Vim?
it may look a little old-fashioned
but it can also be modern : )
So, Why Vim?
Keyboard-driven
Keyboard is King!
and, Why not Vim?
seems very hard to learn..
you won’t use other editors after learning Vim..
Today, we have 2 Goals..
no Mouse
no Arrow keys
muscle memory
Tips
in terminal: 1. ctrl + z to stash vim, and type fg to bring it back. 2. ctrl + w to delete a word, ctrl + u to delete a whole line, both work in terminal and vim edit mode. 3. ctrl + r to find history commands fuzzily.
