0. Basics of VIM

• normal mode [Esc]
• insert mode [i]
• replace mode

Selection mode - visual - visual line - visual block

• command line model

Notations for control + V

^V
Ctrl-V
<C-V>

the interface itself is a programming language

1. How to insert a string at the beginning of a line

• ctrl-v
• drop down with "down arrow" up to the desired line
• shift + i
• type what ever you want to insert in the first line
• type scape
• then go down with the down arrow, it automatically will appear what you want

2. How to cut and paste (ctrl-v or ctrl-V)

1. take place where your want to start to copy or cut
2. Type ctrl-v if you want to select a character or type cltr-V if you want to select a full line.
3. if you type ctrl-v move the cursor where you want to cut/copy. Or move down if you want to copy/cut several lines.
4. if you want to cut, type Esc then d (delete), if you want to copy, Press Esc then y (yank)
5. then you move where you want to paste, then press Esq then type p (paste)

3. How to find a string

1. Press Esc
2. type: /
3. type what you want to find.
4. Once you find it, press n, to the next ocurrence.

4. how to replace with an / across the string to replace

1. Press Esc
2. Type :%s/stringTolookFor/stringToReplace/

if the string contains an character like /, then type / to scape it.

example:

• before: ()

• after: (https://github.com/c4arl0s/NavigationAndWorkflows#navigationandworkflows)

• type

:%s/()/(https:\/\/github.com\/c4arl0s\/NavigationAndWorkflows#navigationandworkflows)/

• Then type enter.

5. Repeats the last action

1. Press ESC
2. press .

6. Insert a # character at the beginning of the line

1. Press Esc
2. :1,40s/^/# /

7. Find an precise string an replace with something

1. Press ESC
2. :
3. Type

:%s/\<direccionMemoria\>/memoryDirection/

8. Insert a character or string at the end of a selected line

1. Select the line or lines. Type ESC, then ctrl-V.
2. then type: s/$/anyString/

it will looks like this:

:'<,'>s/$/anyString/

9. Insert a consecutive number at the beginning of a selected line

let i=1 | '<,'>g/^/ s//\=printf("%d ",i) / | let i+=1

10. Delete all lines that contains a specific pattern

1. Press Esc
2. type:

:g/.com/d

g - find it globally .com - pattern .com d - delete

• another example: Delete all lines that start with // and it is the end of the line

1. press Esc
2. type:

:%g/^\/\/$/d

// hola
// 
// como estas
//

output:

// hola
// como estas

11. Make lowercase

• Select word, line or several words, then:

:gu

• Select word, line or several words, then:

:gU

13. Find any String inside parenthesis Ex. (http://...) with empty content ()

:%s/(.*)/()/

14. Find a particular character in a line using f

In normal mode

type:

fa - finds the first a ahead of the cursor Fa - fins the first a before of the cursor.

15. Delete only a character

type in normal mode:

x

16. Change inside brackets

in normal mode:

26. Enter insert mode, replacing characters rather than inserting

R

then start typing

27. redo

Type Esc, then

u

tyoe Esc, then

ctrl-r

Type . to repeat the last command

28. insert mode

• i - insert before the cursor
• I - insert at the beginning of the line

• A - insert at the end of the line (append)
• o - insert a new line below the current line
• O - insert a new line above the current line
• ea - insert at the end of the word -

29. remove ... from this line: 1.1 Should Software Engineers Worry About Hardware ......... 23

1.1 Should Software Engineers Worry About Hardware .........

remove all dots after the title, including the number

:%s/\..*$//

%s substitude all lines .. scaped dot twice, because 1.1 could be taken. .* all $ up to the end of the line // replace with nothing.

then the output is

1.1 Should Software Engineers Worry About Hardware

30. Find any line starting by any number

/^[0-9]

31. Delete the last character the end of the line

s/$//

32. Delete the last character at the end of the line if it is a number

s/.[1-9]$//

35. Delete empty lines

:%g/^\s*$/d

36. Delete 1 or more of the preceding spaces at the end of the line

%s/\s\+$//

37. find any header or implementation name file (class.h class.m)

/\<\w*\.h\w*\>/

/\<\w*\.m\w*\>/

38. Find a file's name string like class.swift

/<\w*\.swift\w*>/

39. Find a swift or objective-c method like nameMethod(parameter:)

/\w*(.*:)/

40. Using your last course, find any number of digits at the end of a sentence in any line

/ [0-9]\+$//

Example:

1. [this is a test](blablablabla)  Page 1234

It finds the space character and 1234, remember the space, to find this kind of pattern.

41. Enumerate selected lines

:let i=1 | '<,'>g/^/s//\=i.'. '/ | let i=i+1
