set completeopt=preview

" set cindent
|

```
|
||||
These standard vim settings will make the tab key insert 4 spaces instead of using a tab character, and
|
||||
use preview mode instead of auto-completing when using completion plugins.
|
||||
```vim
|
||||
set encoding=utf-8
|
||||
set nu
|

set hidden
|

set noshowmode

||||
" Disabling backups and swap files (cause problem in servers, messy dirs etc.)
|
||||
" You might want to comment this if you are on an unstable system
|
||||
```
|
||||
We set the encondig to UTF-8 and show the number line. Setting hidden allows you to quit a buffer without saving it. \
|
||||
We don't need showmode since we will be using vim-airline for status.
|
||||
```vim
|
||||
set nobackup
|
||||
set nowritebackup
|
||||
set noswapfile
|
||||
```
|
||||
Backups, swapfiles and others are disabled. If your system is unstable, you might want to delete those lines, however it can cause problems with servers and cause messy folders.

" Using Plug for plugins
|
||||
- `CTRL+Q` -> Close buffer
|
||||
- `CTRL+N` -> Open NERDTree
|
||||
- `\ln` -> Disable highlighting
|
||||
- `'` -> Search by matching inside files (using fzf + ripgrep)
|
||||
- `;` -> Search by matching name of files (using fzf + fd)
|
||||
## Plugin settings

### Vim-airline settings
|
||||
```vim
|
||||
let g:airline_powerline_fonts = 1
|
||||
let g:airline#extensions#tabline#enabled = 1
|
||||
let g:airline_theme='term'
|

let g:airline#extensions#whitespace#enabled = 0
|
||||
```
|
||||
Enable powerline fonts
|
||||
### Fzf settings/tips
|
||||
In order to use fd (fast rust alternative to find) with Fzf, install `fd` and add this to your `.bashrc`:
|
||||
```
|
||||
export FZF_DEFAULT_COMMAND='fd --type f --hidden --exclude .git --exclude .vim'
|
||||
```
|
||||
To use ripgrep, simply install it and use `:Rg` (or the shortcut `'`)
|
||||
### CoC (ConquerOfCompletion) settings/tips
|
||||
In order to install a particular langauge completion, use `:CocInstall` \
|
||||
Here is a small list:
|
||||
- `coc-go` Golang completion
|
||||
- `coc-rls` Rust completion
|
||||
- `coc-pyright` Python completion and static analyzer
|
||||
- `coc-sh` Bash completion
