History of Vim
"In the beginning, there was ed. And ed begat ex; and ex begat vi; and vi begat vim."
What is Vim?
● Vim is a highly customizable, highly efficient text editor
● Vim has several modes○ Normal ○ Insert○ Visual○ Ex mode
Normal Mode
Normal Mode is the default mode in Vim.
You should spend most of your time in normal mode.
Text Objects
a = a/ani = inside
aw -> a wordaW -> a WORD
as -> a sentence
ap -> a paragraph
More Text Objects
a( -> a pair of parenthesis
a{ -> a pair of {braces}
a[ -> a pair of [brackets]
a< -> a pair of <angle brackets>
at -> a pair of XML tags
More Text Objects
a" -> a pair of "quotes"a' -> a pair of 'quotes'
Examples:da" -> delete a pair of quotesci" -> change everything between the quotesyap -> yank a paragraph
Motions
words vs WORDSdef foo(a,b)
word: [def][foo][(][a][,][b][)]WORD: [def][foo(a,b)]
w -> next word e -> end of wordW -> next WORD E -> end of WORD
b-> beginning of current wordB -> beginning of current WORD
More Motions
f -> find a character F -> find a character (reverse)
t -> go to just before a characterT -> go to just after a character (reverse)
; -> next match (for f/F/t/T), -> previous match (for f/F/t/T)
More Motions
/ -> search forward? -> search backwardsn -> next match (current direction)N -> previous match (current direction)
* -> search for word under the cursor# -> search backwards for word under the cursor
Operator
y -> yankd -> deletec -> change
p -> paste (after)P -> paste (before)
Operator + motion = actiondw -> delete to the next word
Line-wise operations
dd -> delete a linecc -> change a lineyy -> yank a line (copy)
>> -> shift right<< -> shift left== -> auto indent
Counts
Most motions take a count3w -> move ahead 3 words5s -> move ahead 3 sentences
These can be combined with actions3dw -> delete a word 3 times (or d3w)5dd -> delete 5 lines2yy -> yank 2 lines
Undo/Redo
Act, Repeat, Reverse
. -> repeat a changeu -> undo a change
- Chunk your Undos- Compose repeatable changes- Don't count if you can repeat
Insert Mode
Entering Insert Modei -> insert to the left of the cursora -> insert to the right of the cursor (append)c -> change (usually combined with a motion)
I -> Insert at the beginning of the current lineA -> Append to the end of the current linecc -> change the current line
Visual Mode
v -> character-wise Visual modeV -> line-wise Visual mode<C-v> -> block-wise Visual modegv -> re-selects last visual selection
You can switch between these without going into normal mode
Ex mode
: -> enter Ex commandQ -> enter Ex mode (:visual to get out)
:[range]d[elete] -> deletes specified lines:[range]y[ank] -> yanks specified lines:[line]put -> puts the yanked lines under the current line
Ex Mode Examples
:5 -> go to line 5:5p -> print line 5:$ -> go to last line:2,5p -> print lines 2-5:% -> the whole document:. -> the current line
Registers
Use registers with yanks and deletesIncrease your clipboard size to 27!
"[register][count]action text object
example:"ayiw => Yank current word into register a"ap => Paste from register a
Macros
Record a sequence of changes and then play them back
q{register} -> record a macro into a registerqa -> start recording a macro into register a
Press q again to stop the recording@{register} -> playback the macro in {register}
Linewise Motions
0 -> go to beginning of a line^ -> first non-whitespace character of a line
$ -> end of line
Macro Tips
Macros can be done in series
Macros can also be done in parallel
Macros are useful with counts (Dot command doesn't accept counts)
