# Welcome to the Neovim Tutorial
# Chapter 1
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.

# CONCLUSION
This concludes Chapter 1 of the Vim Tutor. Consider continuing with
[Chapter 2](@tutor:tutor:vim-02-beginner).
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.

# Welcome to the Neovim Tutorial
# Chapter 2
Hic Sunt Dracones: if this is your first exposure to vim and you
intended to avail yourself of the introductory chapter, kindly type
on the command line of the Vim editor
~~~ cmd
:Tutor vim-01-beginner
~~~
Or just open the [first chapter](@tutor:vim-01-beginner) of the tutor at the link.
The approximate time required to complete this chapter is 8-10 minutes,
depending upon how much time is spent with experimentation.
# Lesson 2.1.1: THE NAMED REGISTERS
** Store two yanked words concurrently and then paste them **
1. Move the cursor to the line below marked ✓
2. Navigate to any point on the word 'Edward' and type `"ayiw`{normal}
**MNEMONIC**: *into register(") named (a) (y)ank (i)nner (w)ord*
3. Navigate forward to the word 'cookie' (`fk`{normal} or `2fc`{normal}
or `$2b`{normal} or `/co`{normal} `<ENTER>`{normal}) and type `"byiw`{normal}
4. Navigate to any point on the word 'Vince' and type `ciw<CTRL-r>a<ESC>`{normal}
**MNEMONIC**: *(c)hange (i)nner (w)ord with <contents of (r)egister> named (a)*
5. Navigate to any point on the word 'cake' and type `ciw<CTRL-r>b<ESC>`{normal}
a) Edward will henceforth be in charge of the cookie rations
b) In this capacity, Vince will have sole cake discretionary powers
NOTE: Delete also works into registers, i.e. `"sdiw`{normal} will delete
the word under the cursor into register s.
REFERENCE: [Registers](registers)
[Named Registers](quotea)
[Motion](text-objects)
[CTRL-R](i_CTRL-R)
# Lesson 2.1.2: THE EXPRESSION REGISTER
** Insert the results of calculations on the fly **
1. Move the cursor to the line below marked ✗
2. Navigate to any point on the supplied number
3. Type `ciw<CTRL-r>=`{normal}60\*60\*24 `<ENTER>`{normal}
4. On the next line, enter insert mode and add today's date with
`<CTRL-r>=`{normal}`system('date')`{vim} `<ENTER>`{normal}
NOTE: All calls to system are OS dependent, e.g. on Windows use
`system('date /t')`{vim} or `:r!date /t`{vim}
I have forgotten the exact number of seconds in a day, is it 84600?
Today's date is:
NOTE: the same can be achieved with `:pu=`{normal}`system('date')`{vim}
or, with fewer keystrokes `:r!date`{vim}
REFERENCE: [Expression Register](quote=)
# Lesson 2.1.3: THE NUMBERED REGISTERS
** Press `yy`{normal} and `dd`{normal} to witness their effect on the registers **
1. Move the cursor to the line below marked ✓
2. yank the zeroth line, then inspect registers with `:reg`{vim} `<ENTER>`{normal}
3. delete line 0. with `"cdd`{normal}, then inspect registers
(Where do you expect line 0 to be?)
4. continue deleting each successive line, inspecting `:reg`{vim} as you go
NOTE: You should notice that old full-line deletions move down the list
as new full-line deletions are added
5. Now (p)aste the following registers in order; c, 7, 4, 8, 2. i.e. `"7p`{normal}
0. This
9. wobble
8. secret
7. is
6. on
5. axis
4. a
3. war
2. message
1. tribute
NOTE: Whole line deletions (`dd`{normal}) are much longer lived in the
numbered registers than whole line yanks, or deletions involving
smaller movements
REFERENCE: [Numbered Registers](quote0)
# Lesson 2.1.4: THE BEAUTY OF MARKS
** Code monkey arithmetic avoidance **
NOTE: a common conundrum when coding is moving around large chunks of code.
The following technique helps avoid number line calculations associated
with operations like `"a147d`{normal} or `:945,1091d a`{vim} or even worse
using `i<CTRL-r>=`{normal}1091-945 `<ENTER>`{normal} first
1. Move the cursor to the line below marked ✓
2. Go to the first line of the function and mark it with `ma`{normal}
NOTE: exact position on line is NOT important!
3. Navigate to the end of the line and then the end of the code block
with `$%`{normal}
4. Delete the block into register a with `"ad'a`{normal}
**MNEMONIC**: *into register(") named (a) put the (d)eletion from the cursor to
the LINE containing mark(') (a)*
5. Paste the block between BBB and CCC `"ap`{normal}
NOTE: practice this operation multiple times to become fluent `ma$%"ad'a`{normal}
~~~ cmd
AAA
function itGotRealBigRealFast() {
if ( somethingIsTrue ) {
doIt()
}
// the taxonomy of our function has changed and it
// no longer makes alphabetical sense in its current position
// imagine hundreds of lines of code
// naively you could navigate to the start and end and record or
// remember each line number
}
BBB
CCC
~~~
NOTE: marks and registers do not share a namespace, therefore register a is
completely independent of mark a. This is not true of registers and
macros.
REFERENCE: [Marks](marks)
[Mark Motions](mark-motions) (difference between ' and \`)
# Lesson 2.1 SUMMARY
1. To store (yank, delete) text into, and retrieve (paste) from, a total of
26 registers (a-z)
2. Yank a whole word from anywhere within a word: `yiw`{normal}
3. Change a whole word from anywhere within a word: `ciw`{normal}
4. Insert text directly from registers in insert mode: `<CTRL-r>a`{normal}
5. Insert the results of simple arithmetic operations:
`<CTRL-r>=`{normal}60\*60 `<ENTER>`{normal} in insert mode
6. Insert the results of system calls:
`<CTRL-r>=`{normal}`system('ls -1')`{vim} in insert mode
7. Inspect registers with `:reg`{vim}
8. Learn the final destination of whole line deletions: `dd`{normal} in
the numbered registers, i.e. descending from register 1 - 9. Appreciate
that whole line deletions are preserved in the numbered registers longer
than any other operation
9. Learn the final destination of all yanks in the numbered registers and
how ephemeral they are
10. Place marks from command mode `m[a-zA-Z0-9]`{normal}
11. Move line-wise to a mark with `'`{normal}
# CONCLUSION
This concludes chapter two of the Vim Tutor. It is a work in progress.
This chapter was written by Paul D. Parker.
