neovim setup for solidity

It has been over 2.5 months now since the solidity-analyzer introduction post and the development has been slow after the burst of development after start. Next things to do for me on solidity-analyzer is to add code navigation and I have been thinking of using tree-sitter for it.

I recently started using nvim again since I wanted to test the LSP with something other than VSCode too. I figured out how to hook solidity-analyzer into nvim past week and have added the same to the project readme as well and is likely to be more up-to-date than this post.

Here’s how:

local configs = require 'lspconfig.configs'
local lspconfig = require 'lspconfig'

-- Check if the config is already defined (useful when reloading this file)
if not configs.solidity_analyer_lsp then
  configs.solidity_analyzer_lsp = {
    default_config = {
      cmd = {vim.fn.expand('$HOME/.cargo/bin/solidity-analyzer-ls')},
      filetypes = {'solidity'},
      root_dir = lspconfig.util.root_pattern('foundry.toml') or function(fname)
        return lspconfig.util.find_git_ancestor(fname)
      end,
      settings = {},
    },
  }
end

lspconfig.solidity_analyzer_lsp.setup{}

This is what I have along with the kickstart.nvim starter config which adds a bunch of lsp utilities and most importantly the on_attach handler for LSP.

Another thing I have is nvim-treesitter-context configured for solidity. The config for which is quite simple and is more documented in their readme.

Here’s my excerpt:

require "treesitter-context".setup {
  mode = "topline",
}
