NeoVim中Omnisharp LSP跳转定义功能报错求助

问题说明 #

配置NeoVim中Omnisharp LSP的跳转定义功能，已按文档要求安装omnisharp_extended，但触发跳转时出现报错。其他LSP的跳转定义功能正常，仅Omnisharp存在问题。已确认LSP已附加到缓冲区、omnisharp_extended已正确安装，点击报错提示的回车后会跳转到空白界面。

配置代码 #

require('mason-lspconfig').setup {
  handlers = {
    omnisharp = function()
      local config = {
        ['textDocument/definition'] = require('omnisharp_extended').definition_handler,
        ['textDocument/typeDefinition'] = require('omnisharp_extended').type_definition_handler,
        ['textDocument/references'] = require('omnisharp_extended').references_handler,
        ['textDocument/implementation'] = require('omnisharp_extended').implementation_handler,
      }
      require('lspconfig').omnisharp.setup(config)
    end,
    function(server_name)
      local server = servers[server_name] or {}
      -- This handles overriding only values explicitly passed
      -- by the server configuration above. Useful when disabling
      -- certain features of an LSP (for example, turning off formatting for ts_ls)
      server.capabilities = vim.tbl_deep_extend('force', {}, capabilities, server.capabilities or {})
      require('lspconfig')[server_name].setup(server)
    end,
  },
}

Error executing vim.schedule lua callback: ...ar/neovim/0.10.2/share/nvim/runtime/lua/vim/lsp/util.lua:1142: Cursor position outside buffer

解决思路建议 #

• 升级omnisharp_extended到最新版本：旧版本可能与NeoVim 0.10.2存在兼容性问题，导致返回的位置信息格式异常
• 调整配置结构：将omnisharp_extended的handler配置放到handlers子字段中，并确保传递基础的capabilities，示例调整后的配置：

  require('mason-lspconfig').setup {
    handlers = {
      omnisharp = function()
        -- 初始化基础capabilities，可根据需求添加cmp等扩展
        local capabilities = vim.lsp.protocol.make_client_capabilities()
        local config = {
          capabilities = capabilities,
          handlers = {
            ['textDocument/definition'] = require('omnisharp_extended').definition_handler,
            ['textDocument/typeDefinition'] = require('omnisharp_extended').type_definition_handler,
            ['textDocument/references'] = require('omnisharp_extended').references_handler,
            ['textDocument/implementation'] = require('omnisharp_extended').implementation_handler,
          }
        }
        require('lspconfig').omnisharp.setup(config)
      end,
      function(server_name)
        local server = servers[server_name] or {}
        server.capabilities = vim.tbl_deep_extend('force', {}, capabilities, server.capabilities or {})
        require('lspconfig')[server_name].setup(server)
      end,
    },
  }
  

• 更新Omnisharp服务器：通过Mason将Omnisharp更新到最新稳定版，旧服务器返回的位置数据可能无法被omnisharp_extended正确解析
• 测试原生LSP跳转：暂时禁用Telescope，直接执行:lua vim.lsp.buf.definition()测试跳转，排查是否是Telescope与omnisharp_extended的兼容性问题
• 检查目标文件路径：确认跳转目标文件存在，且路径无特殊字符或编码问题，Omnisharp对特殊路径的解析可能出现异常
