How to install Control-P for vim?

https://ctrlpvim.github.io/ctrlp.vim/

Clone the plugin into a separate directory:

$ cd ~/.vim
$ git clone https://github.com/ctrlpvim/ctrlp.vim.git bundle/ctrlp.vim

Add to your ~/.vimrc:

set runtimepath^=~/.vim/bundle/ctrlp.vim

Run at Vim's command line:
```
:helptags ~/.vim/bundle/ctrlp.vim/doc
```
Restart Vim and check :help ctrlp.txt (or simply :help ctrlp) for usage instructions and configuration details.
When CtrlP helps find the file you want to open, if you simple press Enter, it will fill the current full window. Maybe that is not what you want.
If you want to split the current window vertically and open it, press Ctrl-V;
If you want to split the current window horizontally,, and open it, press Ctrl-S.
If you want to open the file on a new tab, press Ctrl-T.

How to install vim plugin from github?

e.g.1 install ctrlp from github

https://howchoo.com/vim/how-to-install-ctrlp-fuzzy-finder-for-vim

Clone the plugin from the git repository

To clone from github:

git clone https://github.com/kien/ctrlp.vim.git ~/.vim/bundle/ctrlp.vim

Update your vimrc

Add the following to your vimrc file:

set runtimepath^=~/.vim/bundle/ctrlp.vim

To edit vimrc, type:

vim ~/.vimrc

Restart vim

============================

e.g. 2 install airline from github

https://superuser.com/questions/634570/vim-how-to-install-airline

git clone https://github.com/bling/vim-airline ~/.vim/bundle/vim-airline

Put the following line into ~/.vimrc

set funtimepath^=~/.vim/bundle/vim-airline

I got :help airline to work with this command:

:helptags ~/.vim/bundle/vim-airline/doc

Like you, now the help-page displays when I type :help airline.

To add airline and the buffer list, install airline, and then just add this to your .vimrc:

" Enable the list of buffers

let g:airline#extensions#tabline#enabled = 1

" Show just the filename

let g:airline#extensions#tabline#fnamemod = ':t'

Next I needed to replace the tab shortcuts that I’d no longer be using. I did this by adding these to my .vimrc as well:

" This allows buffers to be hidden if you've modified a buffer.

" This is almost a must if you wish to use buffers in this way.

set hidden

" To open a new empty buffer

" This replaces :tabnew which I used to bind to this mapping

nmap <leader>T :enew<cr>

" Move to the next buffer

nmap <leader>l :bnext<CR>

" Move to the previous buffer

nmap <leader>h :bprevious<CR>

" Close the current buffer and move to the previous one

" This replicates the idea of closing a tab

nmap <leader>bq :bp <BAR> bd #<CR>

" Show all open buffers and their status

nmap <leader>bl :ls<CR>

These settings gave me a hybrid approach to how I expected tabs to work in Vim yet it still gave me the same power that comes from understanding and using buffers.
