neovim-config/README.md

The config is complete but still work in progress as I am new to lua and slowly learning vim stuffs. I'll keep adding new features like snippets etc and clean the config , make neovim (cli version) as functional as an IDE while being eyecandy. Pull requests are welcome.

# Very Useful lua plugins used in my config -

#### lspkind-nvim

This tiny plugin adds vscode-like pictograms to neovim built-in lsp completion items :

#### nvim-tree.lua

fast file tree :

<kbd><img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/nvimtree.png"></kbd><hr>

### telescope-nvim -

A fuzzy file finder, picker, sorter, previewer and much more:

<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/telmedia.png"></kbd><hr>

### indent-blankline.nvim -

adds indentline :
<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/blanklineNvim.png"></kbd>

using indenLine plugin on left and blanklineNvim on right

### galaxyline -

fastest statusline plugin I've used so far:
<kbd><img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/statusline.png"></kbd><hr>

### gitsigns.nvim -

Shows git signs of a repo on the signcolumn to indicate diffs/changes etc (needs plenary.nvim)

<hr>

### nvim-bufferline.lua -

As a top bufferline like thing which lets me handle tabs like switching, closing tabs.
<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/bufferline.png"></kbd>

<hr>
 
### nvim-web-devicons -
Lua fork of vim devicons which lets me change icons of filetypes
<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/image.png"></kbd><hr>
 
### nvim-treesitter 
Better syntax highlighting for programming languages ( my config just has html,css,js support for now ).

without Treesitter :
<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/woTree.png"></kbd>

with Treesitter :
<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/wiTree.png"></kbd><hr>

### nvim-base16 -

contains a collection of all base16 themes for vim , plugin written in lua (comparison of base16-vim and nvim-base16):

nvim-base16 doesnt even take time to load unlike base16-vim which was eating half of the loadup time! ( the below screenshot was taken and tested on my old pentium laptop , so results might differ)
<kbd> <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/nvim-base16.png"></kbd><hr>

(neovim loads pretty fast on ssds)

# Config structure

```
     nvim
      ├──init.lua
      └──lua
          └──foo
              └──lua.lua
```

- The init.lua is used instead of init.vim.

- The lua folder contains modules ( config files ) , in the example above "foo" folder could be considered as a module and it contains a lua.lua.
- The lua.lua file is supposed to have any nvim config written in lua , its like splitting the overall config into small bits and make it more organized.
- To load or source that "foo" module  (like making it load with init.lua )  , you need to load it in init.lua like this : require('foo.lua').

# Features

- File navigation with Nvimtree
- mouse works
- managing tabs with bufferline
- autosave
- icons on nvimtree , telescope , bufferline/statusline and almost everywhere! with nvim-web-devicons
- minimal status line ( galaxyline)
- gitsigns (colored bars in my config)
- using nvim-lsp
- nvim-lspconfig for nvim-lps configuration
- nvim-compe for autocompletion
- lspkind to show pictograms on autocompletion items
- telescope for file finding , picking , previewing (files and even images)
- nvim-treesitter for syntax highlighting
- nvim-autopairs , for autolosing braces and stuffs
- neoformat for prettifying / formatting code
- packer.nvim as package manager
- indent-blankline.Nvim for indentlines
- smooth scrolling

# Guides to migrate your nvim configs to init.lua -

# Clone my setup -

- Install neovim-nightly , also use a nerdfont on your terminal.
- run the install.sh (this might work only on nix systems) and open neovim , do :PackerInstall
- Install ripgrep , fd , ueberzug for telescope media extension to work. 

- Manual installation , incase the install.sh doesnt work for you :

- Install packer.nvim

```shell
git clone https://github.com/wbthomason/packer.nvim\
 ~/.local/share/nvim/site/pack/packer/start/packer.nvim
```

- copy lua folder and init.lua into ~/.config/nvim
- Open neovim and install all plugins , :PackerInstall (let treesitter install all its extensionsm
- Install language servers and prettier ( for autocompletion etc and code formatting , nodejs should be installed too!) , this usually depends on the language support you want to add in your neovim config.

```
sudo npm install -g vscode-html-languageserver-bin typescript typescript-language-server  vscode-css-languageserver-bin prettier
```

To setup any language server , follow this guide https://github.com/neovim/nvim-lspconfig/blob/master/CONFIG.md and search up the needed LSP. For example if I needed clangd's lsp server :

 <kbd>
 <img src = "https://raw.githubusercontent.com/siduck76/dotfiles/master/rice%20flex/clang.png">
  </kbd>

I'd install it first and add its setup line :
`` -- in /lua/nvim-lspconfig/lua.lua file

       require'lspconfig'.clangd.setup{}  ``

# Default Mappings to make stuffs easier!

<kbd> space </kbd> is the leader key

- <kbd> Ctrl </kbd> <kbd> l </kbd> Open terminal vertically over right
- <kbd> Ctrl </kbd> <kbd> x </kbd> Open terminal horizontally below the current window
- <kbd> Ctrl </kbd> <kbd> n </kbd> toggle neovim tree
- <kbd> Shift </kbd> <kbd> n </kbd> toggle line number
- <kbd> Ctrl </kbd> <kbd> a </kbd> copies everything in the current file
- select any text + <kbd> y </kbd> copies the selected text
- leader + <kbd> f </kbd> <kbd> b </kbd> open all buffers , with telescope
- leader + <kbd> f </kbd> <kbd> p </kbd> search and preview images with telescope
- leader + <kbd> f </kbd> <kbd> f </kbd> find files in the current DIR , with telescope
- leader + <kbd> f </kbd> <kbd> o </kbd> open recently edited files , with telescope
- leader + <kbd> f </kbd> <kbd> f </kbd> find files in the current DIR , with telescope
- leader + <kbd> f </kbd> <kbd> h </kbd> opens up a manpage like thing but for all vim related things , with telescope
- leader + <kbd> f </kbd> <kbd> m </kbd> formats or beautifies the code in current window via neoformat
  (currently only html ,css , js can be formatted . To be able to use this keybind you need to install the formatter locally for your language , in my case prettier was required only so I installed it. check this <a> https://github.com/sbdchd/neoformat</a>).
