vim

I'll never get used to it. Let's get started and learn..

save with sudo

I need it every day, I just can't remember it. needs to be on the top. when you get this (opening and editing a file as a regular user but the file is owned by someone else): 'readonly' option is set (add ! to override), do this:

:w !sudo tee %

indent multiple lines by n spaces

n is 2 in this example

set shiftwidth=2

select multiple lines with v (visual mode) and do > or < to go the other way

another way:

1. select the lines you want with V, hit : and do le4 where 4 is the number of spaces

Vjj:le4

(V for visual mode, jj for selecting two lines (you can also use your arrow keys), :le4 to indent by 4 spaces)

prepend text / multiple cursors

1. press control + v to go into visual block mode
2. select your lines, either with the arrow keys or j / k
3. press shift + i start whatever you want to prepend, like # to comment something out
4. press ESC

convert tabs to spaces

that's correct.

:set tabstop=4 shiftwidth=4 expandtab

create new file

vim file.md

create new file while vim is open:

:e other-filename.md

paste from external clipboard

Ctrl + Shift + V

thank you.

vertical highlighting

ctrl + v

thank you.

search

search and replace within the whole document:

%s/search-term/replace-term/g

search and replace interactively term by term:

%s/search-term/replace-term/gc

useful plugins

nerdtree

• cool vim tree explorer plugin

switch to nerdtree window

ctrl + ww

toggle nerdtree window

open, close, open, close. bed up, bed down, bed up, bed down

that's the default:

:NERDTreeToggle

add something like this to your `~/.vimrc`` file

nnoremap <Leader>f :NERDTreeToggle<Enter>

with this line you can toggle nerdtree with \f given that \ is your leader key.

reload tree

r

or reload the whole folder structure:

R
