my own vim memo
This post just tries to summarize some frequently used vim commands that I can not remember (which is unforuante):
Copy matched search result to a different buffer
qaq " what this does is to clear the content of the register 'a'
:g/pattern/y A " what this does is to copy the search result to register 'a'
:tabnew "create a new tab
"ap "paste the content of register 'a' to the current buffer

Append characters at the end of lines
# assume you just want to append a ',' at the end of each line
:%s /$/,/
Surround each line with double quotes
:%s /.*/"&"/
Swap matched gruops
e.g. you have a string like a -> b, and want to swap it to b -> a
What you need to do is:
:%s /\(\w*\) -> \(\w*\)/\2 -> \1/g
Note: what’s tricky here is that you have to escape ‘(,)’ using ‘'

termguicolors doesn’t work on MacOS’s built-in terminal.app
I ran into this when I tried to use the built-in Terminal.app from MacOS. And I noticed no colors are rendered in it when I open any files in it. And after remove the termguicolors option from vimrc/init.vim, the synthax highlight comes back.
And a related discussion can be found here: https://stackoverflow.com/questions/58674310/nvim-in-macos-terminal-breaks-on-displaying-termguicolors
MacVim settings
There are some special(weird) settings about MacVim, which has made me so confused. e.g. to set the font size or colorscheme, the settings you have in .vimrc don’t work as you expect. The reality is that you have to configure those in .gvimrc instead of .vimrc. Take a look at this .gvimrc for what the settings look like.
