[Vim](http://www.vim.org)
|
|
(Vi IMproved) is a clone of the popular vi editor for Unix. It is a text
|
|
editor designed for speed and increased productivity, and is ubiquitous in most
|
|
unix-based systems. It has numerous keybindings for speedy navigation to
|
|
specific points in the file, and for fast editing.
|
|
|
|
## Basics of navigating Vim
|
|
|
|
```
|
|
vim <filename> # Open <filename> in vim
|
|
:help <topic> # Open up built-in help docs about <topic> if any exists
|
|
:q # Quit vim
|
|
:w # Save current file
|
|
:wq # Save file and quit vim
|
|
ZZ # Save file and quit vim
|
|
:q! # Quit vim without saving file
|
|
# ! *forces* :q to execute, hence quiting vim without saving
|
|
:x # Save file and quit vim, shorter version of :wq
|
|
|
|
u # Undo
|
|
CTRL+R # Redo
|
|
|
|
h # Move left one character
|
|
j # Move down one line
|
|
k # Move up one line
|
|
l # Move right one character
|
|
|
|
Ctrl+B # Move back one full screen
|
|
Ctrl+F # Move forward one full screen

:%s/foo/bar/g # Change 'foo' to 'bar' on every line in the file
|
|
:s/foo/bar/g # Change 'foo' to 'bar' on the current line
|
|
:%s/\n/\r/g # Replace new line characters with new line characters
|
|
|
|
# Jumping to characters
|
|
|
|
f<character> # Jump forward and land on <character>
|
|
t<character> # Jump forward and land right before <character>
|
|
|
|
# For example,
|
|
f< # Jump forward and land on <
|
|
t< # Jump forward and land right before <
|
|
|
|
# Moving by word
|
|
|
|
w # Move forward by one word
|

|
|
|
|
# Other characters for moving around
|
|
|
|

|
|
G # Go to the bottom of the file
|
|
:NUM # Go to line number NUM (NUM is any number)
|
|
H # Move to the top of the screen

|
|
```
|
|
|
|
## Help docs:
|
|
|
|
Vim has built in help documentation that can accessed with `:help <topic>`.
|
|
For example `:help navigation` will pull up documentation about how to navigate
|
|
your workspace!
|
|
|
|
`:help` can also be used without an option. This will bring up a default help dialog
|
|
that aims to make getting started with vim more approachable!
|
|
|
|
## Modes:
|
|
|
|
Vim is based on the concept on **modes**.
|
|
|
|
Command Mode - vim starts up in this mode, used to navigate and write commands
|
|
Insert Mode - used to make changes in your file
|
|
Visual Mode - used to highlight text and do operations to them
|
|
Ex Mode - used to drop down to the bottom with the ':' prompt to enter commands
|
|
|
|
```
|
|
i # Puts vim into insert mode, before the cursor position
|
|
a # Puts vim into insert mode, after the cursor position
|
|
v # Puts vim into visual mode
|
|
: # Puts vim into ex mode
|
|
<esc> # 'Escapes' from whichever mode you're in, into Command mode
|
|
|
|
# Copying and pasting text
|
|
|
|
y # Yank whatever is selected
|
|
yy # Yank the current line
|
|
d # Delete whatever is selected
|
|
dd # Delete the current line
|
|
p # Paste the copied text after the current cursor position
|
|
P # Paste the copied text before the current cursor position
|
|
x # Deleting character under current cursor position
|
|
```
|
|
|
|
## The 'Grammar' of vim
|
|
|
|
Vim can be thought of as a set of commands in a
|
|
'Verb-Modifier-Noun' format, where:
|
|
|
|
Verb - your action
|
|
Modifier - how you're doing your action
|
|
Noun - the object on which your action acts on
|
|
|
|
A few important examples of 'Verbs', 'Modifiers', and 'Nouns':
|
|
|
|
```
|
|
# 'Verbs'
|
|
|
|
d # Delete
|
|
c # Change
|
|
y # Yank (copy)
|
|
v # Visually select
|
|
|
|
# 'Modifiers'
|
|
|
|
i # Inside
|
|
a # Around
|
|
NUM # Number (NUM is any number)
|
|
f # Searches for something and lands on it
|
|
t # Searches for something and stops before it
|
|
/ # Finds a string from cursor onwards
|
|
? # Finds a string before cursor
|
|
|
|
# 'Nouns'
|
|
|
|
w # Word
|
|
s # Sentence
|
|
p # Paragraph
|
|
b # Block
|
|
|
|
# Sample 'sentences' or commands
|
|
|
|
d2w # Delete 2 words
|
|
cis # Change inside sentence
|
|
yip # Yank inside paragraph (copy the para you're in)
|
|
ct< # Change to open bracket
|
|
# Change the text from where you are to the next open bracket
|
|
d$ # Delete till end of line
|
|
```
|
|
|
|
## Some shortcuts and tricks
|
|
|
|
<!--TODO: Add more!-->
|
|
```
|
|
> # Indent selection by one block
|
|
< # Dedent selection by one block
|
|
:earlier 15m # Reverts the document back to how it was 15 minutes ago
|
|
:later 15m # Reverse above command
|
|
ddp # Swap position of consecutive lines, dd then p
|
|
. # Repeat previous action
|
|
:w !sudo tee % # Save the current file as root
|
|
:set syntax=c # Set syntax highlighting to 'c'
|
|
:sort # Sort all lines
|
|
:sort! # Sort all lines in reverse
|
|
:sort u # Sort all lines and remove duplicates
|
|
~ # Toggle letter case of selected text
|
|
u # Selected text to lower case
|
|
U # Selected text to upper case
|
|
|
|
# Fold text
|
|
zf # Create fold from selected text
|
|
zo # Open current fold
|
|
zc # Close current fold
|
|
zR # Open all folds
|
|
zM # Close all folds
|
|
```
|
|
|
|
## Macros
|
|
|
|
Macros are basically recordable actions.
|
|
When you start recording a macro, it records **every** action and command
|
|
you use, until you stop recording. On invoking a macro, it applies the exact
|
|
same sequence of actions and commands again on the text selection.
|
|
|
|
```
|
|
qa # Start recording a macro named 'a'
|
|
q # Stop recording
|
|
@a # Play back the macro
|
|
```
|
|
|
|
### Configuring ~/.vimrc
|
|
|
|
The .vimrc file can be used to configure Vim on startup.
|
|
|
|
Here's a sample ~/.vimrc file:
|
|
|
|
```
|
|
" Example ~/.vimrc
|
|
" 2015.10
|
|
|
|
" Required for vim to be iMproved
|
|
set nocompatible
|
|
|
|
" Determines filetype from name to allow intelligent auto-indenting, etc.
|
|
filetype indent plugin on
|
|
|
|
" Enable syntax highlighting
|
|
syntax on
|
|
|
|
" Better command-line completion
|
|
set wildmenu
|
|
|
|
" Use case insensitive search except when using capital letters
|
|
set ignorecase
|
|
set smartcase
|
|
|
|
" When opening a new line and no file-specific indenting is enabled,
|
|
" keep same indent as the line you're currently on
|
|
set autoindent
|
|
|
|
" Display line numbers on the left
|
|
set number
|
|
|
|
" Indentation options, change according to personal preference
|
|
|
|
" Number of visual spaces per TAB
|
|
set tabstop=4
|
|
|
|
" Number of spaces in TAB when editing
|
|
set softtabstop=4
|
|
|
|
" Number of spaces indented when reindent operations (>> and <<) are used
|
|
set shiftwidth=4
|
|
|
|
" Convert TABs to spaces
|
|
set expandtab
|
|
|
|
" Enable intelligent tabbing and spacing for indentation and alignment
|
|
set smarttab
|
|
```
|
