Powerline

Need to install powerline with pip

Config:

" Allow Powerline style
set rtp+=.local/lib/python3.7/site-packages/powerline/bindings/vim/
" These lines setup the environment to show graphics and colors correctly.
set laststatus=2
set t_Co=256

YAML

Maybe use this config:

" Allow YAML tab styling
autocmd FileType yaml setlocal ts=2 sts=2 sw=2 expandtab
let g:indentLine_char_list = ['|', '¦', '?', '?']    

Wired backspace?

in vim [backspace] or backwards delete leaves a wired symbol ^? and does not delete anything? Add this to your ~/.vimrc:

" Allow backspace
noremap! <C-?> <C-h>

The source of this error relates to stty and maybe VNC. on stackoverflow

or maybe

# in .bashrc
# fix for vim backspace
stty erase '^?'

VIM Diff

Visually compare two files, highlighting the differences. You can easily switch between files (CTRL+w) and move parts from one file to another (do do obtain or dp do put).
