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).

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)

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