my-nvim-lua/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 :

### 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>

### 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 :

# Config structure

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

- The init.lua is used instead of init.vim.
- The lua folder contains modules , in the example above "foo" could be considered as a module and it contains a lua.lua file in which you could write your config in lua , its like splitting the overall config into small bit . To load/source that "foo" module , you need to specify 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 script as root or copy the configs manually :
- Install packer.nvim

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

- copy all config files in from this repo except ( plugin folder as it has config related to my system's username! )
- Open neovim and install all plugins , :PackerInstall and :TSUpdate
- Install language servers and prettier ( for autocompletion etc and code formatting , nodejs should be installed too!)

```
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> 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>).
- `<C-u>`, `<C-d>`, `<C-b>`, `<C-f>`, `<C-y>` and `<C-e>` : Smooth scrolling for window movement commands.

# TODO

- add snippets support
- show statusline in inactive windows

# Troubleshooting -

if you get any errors with packer.nvim , then remove the ~/.config/nvim/plugin/packer_nvim.vim file since it just has file paths for my system
and re-install packer.nvim
