Description

Summary

This PR adds comprehensive support for Solidity development in Neovim using LazyVim. The following updates were made to streamline Solidity development:

Changes

  1. Solidity File Type Detection
    • Configured LazyVim to recognize Solidity projects by detecting foundry.toml, hardhat.config.js, and hardhat.config.ts files.
  2. Treesitter Support for Solidity
    • Added solidity to the list of languages ensured by nvim-treesitter, providing syntax highlighting and better code structure understanding.
  3. Language Server Protocol (LSP) Setup
    • Configured nvim-lspconfig to support solidity_ls as the LSP for Solidity files.
    • Set up root_dir detection based on project files or a .git directory to enable proper LSP functioning in Solidity projects.
  4. Solidity Formatter
    • Integrated forge_fmt as a formatter for Solidity files using conform.nvim, which utilizes forge fmt to format code.

Why use forge fmt instead of Prettier?

  • Prettier's Solidity support requires extra plugins: Prettier does not have native Solidity support and depends on prettier-plugin-solidity. Even with vim.g.lazyvim_prettier_needs_config = false, formatting won't work unless a .prettierrc file is configured, creating unnecessary complexity.
  • forge fmt is the native tool for Solidity development: Forge is a widely used tool within the Solidity ecosystem, especially when working with Foundry. It provides built-in formatting with no extra dependencies, making it simpler and more efficient to integrate.
  • Hardhat uses prettier-plugin-solidity: For users of Hardhat, prettier-plugin-solidity is required for code formatting. However, the integration with Prettier might add complexity, while forge fmt simplifies the process.
  • Future customization: We may allow users to choose between prettier-plugin-solidity and forge fmt for formatting in the future, depending on their preferred tools.

Testing

  • Confirmed that Solidity files are detected and syntax-highlighted by Treesitter.
  • Verified LSP functionality for Solidity, including code navigation and error detection.
  • Tested forge_fmt for automatic code formatting on Solidity files.

Motivation

These changes provide a smoother and more robust Solidity development experience in Lazyvim, including syntax highlighting, code navigation, and automatic formatting.

 ## Description

- Add Solidity language support to `nvim-treesitter` for syntax highlighting and enhanced code understanding.
- Configure `nvim-lspconfig` for Solidity LSP support, setting up `solidity_ls` with a root pattern detection for Solidity projects.
- Integrate `forge_fmt` as the formatter for Solidity files using `conform.nvim`, with command options for `forge fmt`.

There's also a neotest adapter for solidity/hardhat

also a neotest adapter for solidity/hardhat

I noticed that these adapters are not maintained frequently and have few users, so I didn't include them.
