local configs = require 'lspconfig.configs'

configs.solidity = {
  default_config = {
    cmd = {'nomicfoundation-solidity-language-server', '--stdio'},
    filetypes = { 'solidity' },
    root_dir = lspconfig.util.find_git_ancestor,
    single_file_support = true,
  },
}

lspconfig.solidity.setup {}
