Personal Vim cheatsheet

Mon, 07 Oct 2019 17:52:00 -0400

This is my personal cheatsheet as intermediate Vim user so I skipped the ones that I consider basic. All the commands listed are used in command mode for fast editing.

Command execution

In command mode, use colon to start ex command. Here are some examples of ex commands:

e: edit file
g: global command
q: quit
w: write
s: substitute

The commands (g)lobal and (s)ubstitute are heavily used in string manipulation. The rest are summarized here:

:e!	reload current file discarding all unsaved changes
:e newfile.txt	open file newfile.txt for editing
:e .	load current directory
:w!	force write (if permission allows)
shift + zz	equivalent to :wq!
shift + zq	equivalent to :q!

Operator

.	repeat last operation
fx	find next character x on the same line

Text Editing

y for yank(copy), i for inside, a for around, d for delete, w for word, p for paragraph or paste. Examples:

yyp	copy current line and insert after
diw	delete the entire word where the cursor sits in (dw deletes from cursor to end of word; db deletes from cursor to beginning of word)
shift + V	select entire line in visual mode (v selects character in visual mode)
2>	visual mode: indent twice on all selected lines edit mode: indent once for 2 lines
3<	visual mode: outdent three times on all selected lines edit mode: outdent once for 3 lines
di”	delete everything between the double quotes surrounding the cursor (exclusive); use c instead of d to finish the same effect with insert mode
di>	delete everything between < and > surrounding the cursor (exclusive); use (c)hange instead of (d)elete to finish the same effect with insert mode
dit	delete everything between tags. e.g. <xml>contenttodelete</xml>
dip	delete the entire paragraph
da’	delete everything between the single quote surrounding the cursor (inclusive); use c instead of d to finish the same effect with insert mode
da}	delete everything between { and } surrounding the cursor (inclusive); use c instead of d to finish the same effect with insert mode
dt.	delete all characters until the next .
i	insert at cursor location
shift + I	move cursor to first non-blank character of line and start in insert mode
a	insert at the location next to cursor
shift + A	move cursor to last non-blank character of line and start in insert mode
0	move to beginning of line. ^ moves to first non-blank character in the line. $ moves to the end of line

Note: wherever d is used in this table, c can be used instead for the same effect but switch to editing mode at the end.

String Manipulation

The general patterns are:

[range]g/pattern/cmd
[range]s/match/replacement/option

If range is not specified, it applies to current line only! To specify the whole file, use % range. You may also specify line range such as “10,20”. Here are some examples:

:%s/bacon/lettuce	For every line of the file, replace the first occurrence of bacon in each line to lettuce
:%s/bacon/lettuce/g	For every line of the file, replace all occurrences of bacon to lettuce
:s/bacon/lettuce	For current line, replace the first occurrence of bacon to lettuce
:s/bacon/lettuce/gi	For current line, replace all occurrences of bacon to lettuce, case insensitive
:g/bacon/d	delete all lines that contain pattern ‘bacon’
:g!/lettuce/d	delete all lines that do not contain pattern ‘lettice’; or use :v/lettuce/d instead
:g/^\s*$/d	delete all blank lines. \s* represents zero or more white spaces

Bookmarking

ma	mark cursor line as bookmark a
`a	jump to cursor position at line a
‘a	jump to beginning of line a
`.	jump to last line where change occurred
“	jump back

Insert Mode

Ctrl + N

Auto complete

Edit and run

While tmux and screen can help split screen in Bash, we sometimes need to split a bash screen to run a quick command when we’re already in vim. This can be done with some simple commands.

:term	Open up a terminal above vim. You can also spell :ter or :terminal
Ctrl+W; Ctrl+W	Press Ctrl+W twice can help you toggle between the terminal and vim buffer
Ctrl+D	Close the terminal

This can be very helpful when you are debugging code and need it run repeatedly. You don’t need to exit vim just to run a command and come back. Note that while you’re in terminal, you can’t use Ctrl+W as a shortcut key to backspace a word. Use Alt + Delete instead.
