Vim

Vim è un editor di testo molto potente, che può essere ampliato ulteriormente tramite plugin vari.

Prima, però, ecco una configurazione base che aggiunge varie funzionalità:

" IMPOSTAZIONI ----------------------------------------------------------- {{{

colorscheme catppuccin_mocha
set spell spelllang=it,en
syntax on 			  			      " Enable type file detection. Vim will be able to try to detect the type of file in use.

filetype plugin on 				      " Load an indent file for the detected file type.
filetype indent on
set foldenable

set hlsearch                          " Automatically highlights search results, to hide them run :noh
set incsearch                         " Searches incrementally as you type.
set ruler                             " Shows the rulers

set encoding=UTF-8
set nobackup                          " Neoclide
set nowritebackup
set updatetime=300
set signcolumn=yes
" }}}

Plugin Manager

Per poter installare dei plugin è necessario installare prima un plugin-manager.

Vundle

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

Dopo aver clonato Vundle sulla propria macchina, inserire le seguenti righe di testo nel file .vimrc

" PLUGINS ---------------------------------------------------------------- {{{

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
"
" All of your Plugins must be added before the following line
" 

call vundle#end()            " required

" }}}

Installazione plugin

Installare un plugin è molto semplice, basta aggiungerlo nel file .vimrc, come da codice sottostante:

" PLUGINS ---------------------------------------------------------------- {{{

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
"
" All of your Plugins must be added before the following line
" 
Plugin 'neoclide/coc.nvim', {'branch': 'release'}
Plugin 'itchyny/vim-cursorword'
Plugin 'preservim/nerdtree'
Plugin 'iamcco/markdown-preview.nvim'
Plugin 'alvan/vim-closetag'
Plugin 'mattn/emmet-vim'
Plugin 'jiangmiao/auto-pairs'
Plugin 'ryanoasis/vim-devicons'
Plugin 'frazrepo/vim-rainbow'
Plugin 'mg979/vim-visual-multi', {'branch': 'master'}
Plugin 'itchyny/lightline.vim'
Plugin 'voldikss/vim-floaterm'
Bundle 'https://github.com/prashanthellina/follow-markdown-links'
Plugin 'mracos/mermaid.vim'
Plugin 'mzlogin/vim-markdown-toc'
Plugin 'bbrtj/vim-vorg-md'
Plugin 'sheerun/vim-polyglot'

call vundle#end()            " required

Una volta salvato il file, digitare :PluginInstall.

Quando l'installazione è completata, è buona norma cancellare la cache del buffer digitando il comando :bdelete.

È possibile ricercare plugin nel Web oppure tramite il comando :PluginSearch. Per aggiornare l'elenco locale dei plugin dal sito vimscripts digitare: :PluginSearch!
