# Overview
### Features 
The main goal of this config is being robust and as lightweight as possible. Nothing fancy, just minimum setup for ide-like(ish) experience.

### Installation

Run checkhealth before cloning my setup

:checkhealth

Then clone this repo to your .config folder, open neovim and wait till installation is over.

git clone https://codeberg.org/philw/nvim ~/.config

After the installation it may require a restart so it can load colorscheme properly

### Further development

After many years, this is the only text editor on my system, so I'll be adding updates as long as I find something better(not gonna happen soon).

### Documentation

## Global Settings

- laststatus = 0: Hide the status line.
- signcolumn = "number": Display line numbers in the sign column.
- autoindent = true: Enable automatic indentation.
- clipboard = "unnamedplus": Use the system clipboard for copy-pasting.
- termguicolors = true: Enable 24-bit RGB color support in the terminal.
- fillchars = "eob: ": Customize end-of-buffer character.
- lazyredraw = false: Disable lazy redrawing for smoother experience.

- netrw_banner = 0: Disable Netrw banner.
- netrw_liststyle = 3: Use a tree-style layout for Netrw.
- netrw_altv = 0: Disable vertical splits for Netrw.
- netrw_winsize = 25: Set Netrw window size.
- netrw_browse_split = 4: Open Netrw in a horizontal split.
- rustfmt_autosave = 1: Enable automatic formatting for Rust files using rustfmt.

- tex_conceal = "abdmg": Enable automatic concealment of LaTeX formatting.
- tex_flavor = "latex": Set the flavor of TeX to LaTeX.
- gitgutter_set_sign_backgrounds = 1: Enable background color for GitGutter signs.

## Auto Commands and custom functions (api.nvim_create_autocmd)

### Format on Save
- Formats the buffer using vim.lsp.buf.format before saving any file.

### Run Prettier and Compile LaTeX on Save
- For JavaScript, TypeScript, CSS, HTML, YAML, Markdown, and JSON files, Prettier is run automatically after saving. Yes, I could use lsp features here but in my case this is the bulletproof setup.
- For LaTeX files (*.tex), VimtexCompile is triggered upon saving to compile the document.(bugged af)

You can add anything you want. Just make sure it's on your system.

### Auto-delete Netrw Hidden Buffers
- Automatically deletes hidden buffers when opening a Netrw window. This is quite helpful for the ToggleVExplorer function.

### ToggleVExplorer
- Toggles the VExplorer window in Neovim.
- If the window is already open, it will be closed; if it is closed, it will be opened in the first window.

## Plugin Management (require("lazy").setup)

The configuration uses Lazy.nvim for plugin management. I've tried them all. This works the best for me.

- airblade/vim-gitgutter: Displays Git changes in the gutter (added, modified, deleted lines).
- lervag/vimtex: Provides LaTeX support, including features like auto-compiling and PDF viewing.
- norcalli/nvim-colorizer.lua: Highlights color codes in files.
- nvim-treesitter/nvim-treesitter: Provides better syntax highlighting and tree-sitter integration.
- neovim/nvim-lspconfig: Set up language servers for autocompletion and LSP features.
- ms-jpq/coq_nvim: Provides autocompletion with COQ (a Neovim completion plugin).
- nvim-telescope/telescope.nvim: A fuzzy finder plugin for file searching and navigation.
- windwp/nvim-autopairs: Automatically closes pairs of parentheses, brackets, etc.

## LSP (Language Server Protocol) Configuration

### Rust Configuration (rust_analyzer)
- Configures rust_analyzer with specific settings:
  - imports.granularity.group = "module": Organizes imports by module.
  - cargo.buildScripts.enable = true: Enable build script support for Cargo.
  - procMacro.enable = true: Enable procedural macro support.

Each language server is set up using lspconfig, and the configuration is ensured with coq autocompletion.

### Mason Setup
- mason.nvim: Automatically installs LSP servers(currently just rust_analyzer) and other tools.

## Key Mappings (keymap.set)

- <leader>e: Toggle the VExplorer window.
- <leader>z: Search and replace the word under the cursor in the entire buffer.
- <leader>a: Select the entire buffer.
- <leader>y: Replace the current line with cc (change the line).
- <C-c>: Yank the current line to the clipboard.
- <C-v>: Paste from the clipboard.
- <C-z>: Undo the last change.
- J and K: Speed up moving the selected text block down or up in visual mode.
- <leader>f: Open Telescope's file finder.
- <leader>g: Open Telescope's live grep search.
- <leader>d: Go to definition (LSP feature).
- <leader>k: Show hover information (LSP feature).
