Vim tutorial and useful installations

Productivity

Why use vim

  • Comes preinstalled on many many Unix-like machines
  • Support for a large and fanatic community
  • Concepts are portable to many full featured IDEs Jet-Brains, VS-Code
  • Vim shortcuts are often avaialble in other unix programs
  • You never stop learning vim

Getting started

Resources to get started:

Interactive tutorial for basic movement

  • vimtutor
  • openvim
  • Type :help in your vim

The mode modal

There are 3 main modes for vim:

  1. Normal mode: Where you move around and do most of the things
  2. Insert mode: Where you insert text in short bursts
  3. Visual mode: For text selection, copy paste, etc

Basic motions

Chaning modes

  • esc: exit back to normal mode

  • i enter insert mode

  • v enter visual mode
    You should always be in visual mode, unless you are inserting text. The power of vim is treating text as repeatable actions.

  • /: Search mode, jump back and forth with n and N

Navigation

  • hjkl for moving around

  • Ctrl+o Jump to the last palce you have viewed

  • Ctrl+i/Tab Jump forward

  • w,b to skip words forward and back

  • Ctrl+d page down

  • Ctrl+u page up

Editing commands

  • c change
  • d delete
  • r replace
  • y yank
  • p paste
  • u undo
  • Ctrl+r redo
  • . repeat the last editing action

You can combine operator + number + motion
Examples:

  • Delete 7 lines down
  • Change word
  • Change between parenthesis

Saving and exiting

  • :w write
  • :q quit
  • :wa write all
  • :wq write and quit TIP: Remap the following to save frustration:
command! Q q
command! W w
command! Wq wq
command! WQ wq
command! WA wa
command! Wa wa
command! Qa qa
command! QA qa

More useful keys

  • > indent selected line or text right
  • < indent selected or text left
  • = Align indentation
  • * Search word under cursor forward
  • # Search word under cursor back
