# Welcome to the Neovim Tutorial
|
|
|
|
Neovim is a very powerful editor that has many commands, too many to explain in
|
|
a tutorial such as this. This tutorial is designed to describe enough of the
|
|
commands that you will be able to easily use Neovim as an all-purpose editor.
|
|
It is IMPORTANT to remember that this tutorial is set up to teach by use. That
|
|
means that you need to do the exercises to learn them properly. If you only
|
|
read the text, you will soon forget what is most important!
|
|
|
|
For now, make sure that your Caps-Lock is off and press the `j`{normal} key enough
|
|
times to move the cursor so that Lesson 0 completely fills the screen.
|
|
|
|
# Lesson 0
|
|
|
|
NOTE: The commands in the lessons will modify the text, but those changes
|
|
won't be saved. Don't worry about messing things up; just remember that
|
|
pressing [<Esc>](<Esc>) and then [u](u) will undo the latest change.
|
|
|
|
This tutorial is interactive, and there are a few things you should know.
|
|
- Type [<Enter>](<Enter>) on links [like this](holy-grail ) to open the linked help section.
|
|
- Or simply type [K](K) on any word to find its documentation!
|
|
- You can close this help window with `:q`{vim}
|
|
- Sometimes you will be required to modify text like
|
|
|
|
this here
|
|
|
|
Once you have done the changes correctly, the ✗ sign at the left will change
|
|
to ✓. I imagine you can already see how neat Neovim can be.
|
|
Other times, you'll be prompted to run a command (I'll explain this later):
|
|
~~~ cmd
|
|
:help <Enter>
|
|
~~~
|
|
or press a sequence of keys
|
|
~~~ normal
|
|
<Esc>0f<Space>d3wP$P
|
|
~~~
|
|
Text within <'s and >'s (like `<Enter>`{normal}) describes a key to press
|
|
instead of text to type.
|
|
|
|
Now, move to the next lesson (use the `j`{normal} key to scroll down).
|
|
|
|
## Lesson 1.1: MOVING THE CURSOR
|
|
|
|
** To move the cursor, press the `h`, `j`, `k`, `l` keys as indicated. **
|
|
|
|
↑
|
|
k Hint: The `h`{normal} key is at the left and moves left.
|
|
← h l → The `l`{normal} key is at the right and moves right.
|
|
j The `j`{normal} key looks like a down arrow.
|
|
↓
|
|
|
|
1. Move the cursor around the screen until you are comfortable.
|
|
|
|
2. Hold down the down key (`j`{normal}) until it repeats.
|
|
Now you know how to move to the next lesson.
|
|
|
|
3. Using the down key, move to Lesson 1.2.
|
|
|
|
NOTE: If you are ever unsure about something you typed, press <Esc> to place
|
|
you in Normal mode. Then retype the command you wanted.
|
|
|
|
NOTE: The cursor keys should also work. But using hjkl you will be able to
|
|
move around much faster, once you get used to it.
|
|
|
|
# Lesson 1.2: EXITING NEOVIM

|
|
|
|
5. Move on to Lesson 2.3 to understand what is happening.
|
|
|
|
# Lesson 2.3: ON OPERATORS AND MOTIONS
|
|
|
|
Many commands that change text are made from an [operator](operator) and a [motion](navigation).
|
|
The format for a delete command with the [d](d) delete operator is as follows:
|
|
|
|
d motion
|
|
|
|
Where:
|
|
d - is the delete operator.
|
|
motion - is what the operator will operate on (listed below).
|
|
|
|
A short list of motions:
|
|
[w](w) - until the start of the next word, EXCLUDING its first character.
|
|
[e](e) - to the end of the current word, INCLUDING the last character.
|
|
[$]($) - to the end of the line, INCLUDING the last character.
|
|
|
|
Thus typing `de`{normal} will delete from the cursor to the end of the word.
|
|
|
|
NOTE: Pressing just the motion while in Normal mode without an operator
|
|
will move the cursor as specified.
|
|
|
|
# Lesson 2.4: USING A COUNT FOR A MOTION
|
|
|
|
** Typing a number before a motion repeats it that many times. **
|
|
|
|
1. Move the cursor to the start of the line marked ✓ below.
|
|
|
|
2. Type `2w`{normal} to move the cursor two words forward.
|
|
|
|
3. Type `3e`{normal} to move the cursor to the end of the third word forward.
|
|
|
|
4. Type `0`{normal} ([zero](0)) to move to the start of the line.
|
|
|
|
5. Repeat steps 2 and 3 with different numbers.
|
|
|
|
This is just a line with words you can move around in.
|
|
|
|
6. Move on to Lesson 2.5.
|
|
|
|
# Lesson 2.5: USING A COUNT TO DELETE MORE
|
|
|
|
** Typing a number with an operator repeats it that many times. **
|
|
|
|
In the combination of the delete operator and a motion mentioned above you
|
|
insert a count before the motion to delete more:
|
|
d number motion
|
|
|
|
1. Move the cursor to the first UPPER CASE word in the line marked ✗.
|
|
|
|
2. Type `d2w`{normal} to delete the two UPPER CASE words
|
|
|
|
3. Repeat steps 1 and 2 with a different count to delete the consecutive
|
|
UPPER CASE words with one command
|
|
|
|
This ABC DE line FGHI JK LMN OP of words is Q RS TUV cleaned up.
|
|
|
|
# Lesson 2.6: OPERATING ON LINES
|
|
|
|
** Type `dd`{normal} to delete a whole line. **
|
|
|
|
Due to the frequency of whole line deletion, the designers of Vi decided
|
|
it would be easier to simply type two d's to delete a line.
|
|
|
|
1. Move the cursor to the second line in the phrase below.
|
|
|
|
2. Type [dd](dd) to delete the line.
|
|
|
|
3. Now move to the fourth line.
|
|
|
|
4. Type `2dd`{normal} to delete two lines.
|
|
|
|
1) Roses are red,
|
|
2) Mud is fun,
|
|
3) Violets are blue,
|
|
4) I have a car,
|
|
5) Clocks tell time,
|
|
6) Sugar is sweet
|
|
7) And so are you.
|
|
|
|
# Lesson 2.7: THE UNDO COMMAND
|
|
|
|
** Press `u`{normal} to undo the last commands, `U`{normal} to fix a whole line. **
|
|
|
|
1. Move the cursor to the line below marked ✗ and place it on the first error.
|
|
|
|
2. Type `x`{normal} to delete the first unwanted character.
|
|
|
|
3. Now type `u`{normal} to undo the last command executed.
|
|
|
|
4. This time fix all the errors on the line using the `x`{normal} command.
|
|
|
|
5. Now type a capital `U`{normal} to return the line to its original state.
|
|
|
|
6. Now type `u`{normal} a few times to undo the `U`{normal} and preceding commands.
|
|
|
|
7. Now type `<C-r>`{normal} (Control + R) a few times to redo the commands.
|
|
|
|
Fiix the errors oon thhis line and reeplace them witth undo.

|
|
the motion takes you. Type `ce`{normal} to change from the cursor to the
|
|
end of the word, `c$`{normal} to change to the end of a line, etc.
|
|
|
|
4. The format for change is:
|
|
|
|
c [number] motion
|
|
|
|
Now go on to the next lesson.
|
|
|
|
# Lesson 4.1: CURSOR LOCATION AND FILE STATUS
|
|
|
|
** Type `<C-g>`{normal} to show your location in a file and the file status.
|
|
Type `G`{normal} to move to a line in the file. **
|
|
|
|
NOTE: Read the entire lesson before executing any of these steps!!
|
|
|
|
1. Hold down the `<Ctrl>`{normal} key and press `g`{normal}. We call this `<C-g>`{normal}.
|
|
A message will appear at the bottom of the page with the filename and
|
|
the position in the file. Remember the line number for Step 3.
|
|
|
|
NOTE: You may see the cursor position in the lower right corner of the
|
|
screen. This happens when the ['ruler']('ruler') option is set.
|
|
|
|
2. Press [G](G) to move you to the bottom of the file.
|
|
Type [gg](gg) to move you to the start of the file.
|
|
|
|
3. Type the number of the line you were on and then `G`{normal}. This will
|
|
return you to the line you were on when you first pressed `<C-g>`{normal}.
|
|
|
|
4. If you feel confident to do this, execute steps 1 through 3.
|
|
|
|
# Lesson 4.2: THE SEARCH COMMAND
|
|
|
|
** Type `/`{normal} followed by a phrase to search for the phrase. **
|
|
|
|
1. In Normal mode type the `/`{normal} character. Notice that it and the
|
|
cursor appear at the bottom of the screen as with the `:`{normal} command.
|
|
|
|
2. Now type 'errroor' `<Enter>`{normal}. This is the word you want to search for.
|
|
|
|
3. To search for the same phrase again, simply type [n](n).
|
|
To search for the same phrase in the opposite direction, type [N](N).
|
|
|
|
4. To search for a phrase in the backward direction, use [?](?) instead of `/`{normal}.
|
|
|
|
5. To go back to where you came from press `<C-o>`{normal}.
|
|
(keep `<Ctrl>`{normal} pressed down while pressing the letter `o`{normal}).
|
|
Repeat to go back further. `<C-i>`{normal} goes forward.
|
|
|
|
"errroor" is not the way to spell error; errroor is an error.
|
|
|
|
NOTE: When the search reaches the end of the file it will continue at the
|
|
start, unless the ['wrapscan']('wrapscan') option has been reset.

# Lesson 4.3: MATCHING PARENTHESES SEARCH
|
|
|
|
** Type `%`{normal} to find a matching ),], or }. **
|
|
|
|
1. Place the cursor on any (, [, or { in the line below marked ✓.

|
|
|
|
3. The cursor will move to the matching parenthesis or bracket.
|
|
|
|
4. Type `%`{normal} to move the cursor to the other matching bracket.
|
|
|
|
5. Move the cursor to another (,),[,],{ or } and see what `%`{normal} does.
|
|
|
|
This ( is a test line with ('s, ['s ] and {'s } in it. ))
|
|
|
|
NOTE: This is very useful in debugging a program with unmatched parentheses!
|
|
|
|
# Lesson 4.4: THE SUBSTITUTE COMMAND
|
|
|
|
** Type `:s/old/new/g` to substitute "new" for "old". **

|
3. Now type
|
|
~~~ cmd
|
|
:s/thee/the/g
|
|
~~~
|
|
Adding the g [flag](:s_flags) means to substitute globally in the line,

|
:#,#s/old/new/g
|
|
~~~
|
|
where # are the line numbers of the range of lines where the
|
|
substitution is to be done (i.e., `1,3` means from line 1 to line 3, inclusive).
|
|
|
|
Type
|
|
~~~ cmd
|
|
:%s/old/new/g
|
|
~~~
|
|
to change every occurrence in the whole file.
|
|
|
|
Type

|
|
|
|
2. Typing `/`{normal} followed by a phrase searches FORWARD for the phrase.
|
|
Typing `?`{normal} followed by a phrase searches BACKWARD for the phrase.
|
|
After a search type `n`{normal} to find the next occurrence in the same
|
|
direction or `N`{normal} to search in the opposite direction.
|
|
`<C-o>`{normal} takes you back to older positions, `<C-i>`{normal} to
|

# Lesson 5.1: HOW TO EXECUTE AN EXTERNAL COMMAND
|
|
|
|
** Type `:!`{vim} followed by an external command to execute that command. **
|
|
|
|
1. Type the familiar command `:`{normal} to set the cursor at the bottom of
|
|
the screen. This allows you to enter a command-line command.
|
|
|
|
2. Now type the [!](!cmd) (exclamation point) character. This allows you to
|
|
execute any external shell command.
|
|
|
|
3. As an example type "ls" following the "!" and then hit `<Enter>`{normal}.
|
|
This will show you a listing of your directory, just as if you were
|
|
at the shell prompt.
|
|
|
|
NOTE: It is possible to execute any external command this way, and you
|
|
can include arguments.
|
|
|
|
NOTE: All `:`{vim} commands are executed when you press `<Enter>`{normal}.
|
|
|
|
# Lesson 5.2: MORE ON WRITING FILES
|
|
|
|
** To save the changes made to the text, type `:w`{vim} FILENAME. **
|
|
|
|
1. Type `:!ls`{vim} to get a listing of your directory.
|
|
You already know you must hit `<Enter>`{normal} after this.
|
|
|
|
2. Choose a filename that does not exist yet, such as TEST.
|
|
|
|
3. Now type:
|
|
~~~ cmd
|
|
:w TEST
|
|
~~~
|
|
(where TEST is the filename you chose.)
|
|
|
|
4. This saves the current file under the name TEST.
|
|
To verify this, type `:!ls`{vim} again to see your directory.
|
|
|
|
NOTE: If you were to exit Neovim and start it again with `nvim TEST`, the file
|
|
would be an exact copy of the tutorial when you saved it.
|
|
|
|
5. Now remove the file by typing:
|
|
~~~ cmd
|
|
:!rm TEST
|
|
~~~
|
|
# Lesson 5.3: SELECTING TEXT TO WRITE
|
|
|
|
** To save part of the file, type `v`{normal} motion `:w FILENAME`{vim}. **
|
|
|
|
1. Move the cursor to this line.
|
|
|
|
2. Press [v](v) and move the cursor to the fifth item below. Notice that the
|
|
text is highlighted.
|
|
|
|
3. Press the `:`{normal} character. At the bottom of the screen
|
|
|
|
`:'<,'>`{vim}
|
|
|
|
will appear.
|
|
|
|
4. Type
|
|
|
|
`:w TEST`{vim}
|
|
|
|
where TEST is a filename that does not exist yet. Verify that you see
|
|
|
|
`:'<,'>w TEST`{vim}
|
|
|
|
before you press `<Enter>`{normal}.
|
|
|
|
5. Neovim will write the selected lines to the file TEST. Use `:!ls`{vim} to see it.
|
|
Do not remove it yet! We will use it in the next lesson.
|
|
|
|
NOTE: Pressing [v](v) starts [Visual selection](visual-mode). You can move the cursor around to
|
|
make the selection bigger or smaller. Then you can use an operator to
|
|
do something with the text. For example, `d`{normal} deletes the text.
|
|
|
|
# Lesson 5.4: RETRIEVING AND MERGING FILES
|
|
|
|
** To retrieve the contents of a file, type `:r FILENAME`{vim}. **
|
|
|
|
1. Place the cursor just above this line.
|
|
|
|
NOTE: After executing Step 2 you will see text from Lesson 5.3. Then move
|
|
DOWN to see this lesson again.
|
|
|
|
2. Now retrieve your TEST file using the command
|
|
|
|
`:r TEST`{vim}
|
|
|
|
where TEST is the name of the file you used.
|
|
The file you retrieve is placed below the cursor line.
|
|
|
|
3. To verify that a file was retrieved, cursor back and notice that there
|
|
are now two copies of Lesson 5.3, the original and the retrieved version.
|
|
|
|
NOTE: You can also read the output of an external command. For example,
|
|
|
|
`:r !ls`{vim}
|
|
|
|
reads the output of the `ls` command and puts it below the cursor.
|
|
|
|
# Lesson 5 SUMMARY
|
|
|
|
1. [:!command](:!cmd) executes an external command.
|
|
|
|
Some useful examples are:
|
|
`:!ls`{vim} - shows a directory listing
|
|
`:!rm FILENAME`{vim} - removes file FILENAME
|
|
|
|
2. [:w](:w) FILENAME writes the current Neovim file to disk with
|
|
name FILENAME.
|
|
|
|
3. [v](v) motion :w FILENAME saves the Visually selected lines in file
|
|
FILENAME.
|
|
|
|
4. [:r](:r) FILENAME retrieves disk file FILENAME and puts it
|
|
below the cursor position.
|
|
|
|
5. [:r !dir](:r!) reads the output of the dir command and
|
|
puts it below the cursor position.
|
|
|
|
# Lesson 6.1: THE OPEN COMMAND
|
|
|
|
** Type `o`{normal} to open a line below the cursor and place you in Insert mode. **
|
|
|
|
1. Move the cursor to the line below marked ✓.
|
|
|
|
2. Type the lowercase letter `o`{normal} to [open](o) up a line BELOW the
|
|
cursor and place you in Insert mode.
|
|
|
|
3. Now type some text and press `<Esc>`{normal} to exit Insert mode.
|
|
|
|
After typing `o`{normal} the cursor is placed on the open line in Insert mode.
|
|
|
|
4. To open up a line ABOVE the cursor, simply type a [capital O](O), rather
|
|
than a lowercase `o`{normal}. Try this on the line below.
|
|
|
|
Open up a line above this by typing O while the cursor is on this line.
|
|
|
|
# Lesson 6.2: THE APPEND COMMAND
|
|
|
|
** Type `a`{normal} to insert text AFTER the cursor. **
|
|
|
|
1. Move the cursor to the start of the line below marked ✗.
|
|
|
|
2. Press `e`{normal} until the cursor is on the end of "li".
|
|
|
|
3. Type the lowercase letter `a`{normal} to [append](a) text AFTER the cursor.
|
|
|
|
4. Complete the word like the line below it. Press `<Esc>`{normal} to exit Insert mode.
|
|
|
|
5. Use `e`{normal} to move to the next incomplete word and repeat steps 3 and 4.
|
|
|
|
This li will allow you to pract appendi text to a line.
|
|
This line will allow you to practice appending text to a line.
|
|
|
|
NOTE: [a](a), [i](i) and [A](A) all go to the same Insert mode, the only
|
|
difference is where the characters are inserted.
|
|
|
|
# Lesson 6.3: ANOTHER WAY TO REPLACE
|
|
|
|
** Type a capital `R`{normal} to replace more than one character. **
|
|
|
|
1. Move the cursor to the first line below marked ✗. Move the cursor to
|
|
the beginning of the first "xxx".
|
|
|
|
2. Now press `R`{normal} ([capital R](R)) and type the number below it in the
|
|
second line, so that it replaces the "xxx".
|
|
|
|
3. Press `<Esc>`{normal} to leave [Replace mode](mode-replace). Notice that
|
|
the rest of the line remains unmodified.
|
|
|
|
4. Repeat the steps to replace the remaining "xxx".
|
|
|
|
Adding 123 to xxx gives you xxx.
|
|
Adding 123 to 456 gives you 579.
|
|
|
|
NOTE: Replace mode is like Insert mode, but every typed character
|
|
replaces an existing character.
|
|
|
|
# Lesson 6.4: COPY AND PASTE TEXT
|
|
|
|
** Use the `y`{normal} operator to copy text and `p`{normal} to put it. **
|

|
|
"first".
|
|
|
|
3. Type `y`{normal} to [yank](yank) (copy) the highlighted text.
|
|
|
|
4. Move the cursor to the end of the next line: `j$`{normal}
|
|
|
|
5. Type `p`{normal} to [put](put) (paste) the text.
|
|
|
|
6. Press `a`{normal} and then type "second". Press `<Esc>`{normal} to leave

|
|
|
|
a) This is the first item.
|
|
b)
|
|
|
|
NOTE: you can use `y`{normal} as an operator: `yw`{normal} yanks one word.
|
|
|
|
NOTE: you can use `P`{normal} to put before the cursor, rather than after.
|
|
|
|
# Lesson 6.5: SET OPTION
|
|
|
|
** Set an option so search and substitute commands ignore case. **
|
|

|
Type `<C-w><C-w>`{normal} to jump from one window to another.
|
|
Type `:q`{vim} to close the help window.
|
|
|
|
You can find help on just about any subject, by giving an argument to the
|
|
":help" command. Try these (don't forget to press <Enter>):
|
|
~~~ cmd
|
|
:help w
|
|
:help c_CTRL-D

~~~
|
|
# Lesson 7.2: CREATE A STARTUP SCRIPT
|
|
|
|
** Enable Neovim features. **
|
|
|
|
Neovim is a very configurable editor. You can customise it any way you like.
|
|
To start using more features create an "init.vim" file.
|
|
|
|
1. Start editing the "init.vim" file.
|
|
|
|
`:call mkdir(stdpath('config'),'p')`{vim}
|
|
`:exe 'edit' stdpath('config').'/init.vim'`{vim}
|
|
|
|
2. Write the file with:
|
|
|
|
`:w`{vim}
|
|
|
|
You can add all your preferred settings to this "init.vim" file.
|
|
For more information type `:help init.vim`{vim}.
|
|
|
|
# Lesson 7.3: COMPLETION
|
|
|
|
** Command line completion with `<C-d>`{normal} and `<Tab>`{normal}. **
|
|
|
|
1. List the contents of the current directory: `:!ls`{vim}
|
|
|
|
2. Type the start of a command: `:e`{vim}
|
|
|

3. Press `<C-d>`{normal} and Neovim will show a list of commands beginning with "e".
|
|
|
|
4. Press `<Tab>`{normal} and Neovim will complete the command name to ":edit".
|
|
|
|
5. Now add a space and the start of an existing file name: `:edit FIL`{vim}
|
|
|
|
6. Press `<Tab>`{normal}. Neovim will complete the name ("FIL" -> "FILE", if it is unique).
|
|
|
|
NOTE: Completion works for many commands. It is especially useful for `:help`{vim}.
|
|
|
|
# Lesson 7 SUMMARY

# CONCLUSION
|
|
|
|
This was intended to give a brief overview of the Neovim editor, just enough to
|
|
allow you to use it fairly easily. It is far from complete as Neovim has
|
|
many many more commands. Consult the help often.
|
|
There are also countless great tutorials and videos to be found online.
