Installation

Follow these steps to set up Neovim with this configuration:

1. Backup Your Existing Configuration

   Before proceeding, it's a good idea to back up your current Neovim configuration. Run the following command in your terminal:

   mv ~/.config/nvim ~/.config/nvim.bak

2. Clone the Configuration Repository:

   Clone the repository containing your Neovim configuration to ~/.config/nvim:

   git clone https://github.com/hadihammurabi/nvim-config.git ~/.config/nvim

LSP Configuration

This setup integrates several language servers and tools to enhance development experience:

• LSP Servers:

  • Go: gopls - Provides IDE features for Go development.
  • Rust: rust-analyzer - Offers Rust-specific features and commands.
  • TypeScript: tsserver - Supports TypeScript development.
  • SQL: sqlls - Adds SQL language support.
  • Lua: lua_ls - Adds Lua language support.
  • Vue: volar - Provides language features for Vue files.
  • Dart: dartls - Adds Dart language support for Flutter and other Dart projects.
  • Kotlin: kotlin_language_server - Adds Kotlin language support.

• LSP Features:

  • Signature Help: Shows function signatures and documentation.
  • Hover Documentation: Displays documentation for code under the cursor.
  • Go to Definition: Navigates to the definition of the symbol under the cursor.
  • Go to Implementation: Jumps to the implementation of a function or method.
  • Show References: Lists all references to the symbol under the cursor.
  • Diagnostics: Displays error and warning diagnostics in the buffer.

• Dependencies:

  • lsp_signature.nvim: Adds signature help to the LSP setup.
  • mason.nvim: Manages LSP servers and other tools.
