Registers(related with recording)

This section will introduce related concept/function of recording function. Which help us to understand how this works, and what we should pay attention to it.

register of vim: register is a superset of macro, it contains more function. In this part we should know, register can store some string or operations to help subsequent use.

Status:
Using :registers or :reg to check those we have registered, or add the registers’s name behind to show those u’re interested in.

:reg a b c 
--- Registers ---
"a register a content
"b register b content
"c register c content

Lifecycle
The information in registers will not disappear with the window closed. But maybe with the system-level’s open-close. we should test this!!! So we can store some snippet,pwd,etc.

Pick
There are many registers like 0~9,a~z,unnamed,etc. 0~9 are the default registers for many operations like del,copy,command,etc.
So for recording, we better using a~z. And It should be noted that the upper version A~Z means add operations to an existing command.’a~z’ is to overwrite it.

Modified
Besides the A~Z works like append in python. There are several way to modify the registers;
Like:

# using 'w' as an example of reg.
:let @w='<what command u want>'

# general version is: (ignore the [])
:let @[reg u want to modify]='[what command u want]'

TODO: we should write a indipendent chapter for the registers in vim.

Usage

This section shows the Usage of Recording. And we will continue to collect some good examples. Then put it below.

• Change to Normal mode and pressed “q”
• Chose reg u want (a~z normally) to start record a macro
• { operations u want to be recorde }
• ->in non-insert mode<- pressed “q” to end recording
• Using “@+reg” to repeat this operations/macro
• 10@+reg to repeat this macro 10times
