‘dumb-jump-go’ is an obsolete command (as of 2020-06-26) dumb jump 不能用了吗?我现在用js 有什么可用的跳转插件吗?

‘dumb-jump-go’ is an obsolete command (as of 2020-06-26); ‘dumb-jump-go’ has been obsoleted by the xref interface.

(add-hook 'xref-backend-functions #'dumb-jump-xref-activate)

我以前用也是和 xref 一起用的

(defun my-find-definition ()
  (interactive)
  (condition-case err
      (call-interactively #'xref-find-definitions)
    (user-error
     (cond
      ((and (featurep 'counsel)
            (counsel-etags-locate-tags-file))
       (call-interactively #'counsel-etags-find-tag-at-point))
      ((commandp 'dumb-jump-go) (call-interactively #'dumb-jump-go))))))

意思是你现在只要把按键绑定到xref-find-definitions,而不再需要绑定到dumb jump的函数,dumb jump现在通过设定xref的backend的方式工作,这样的好处是:

  • 抽象说,更好地利用built-in的基础设施,并提供统一的api
  • 具体来说,如果有dumb jump不支持的major mode,但是major mode自己提供了find definition的功能,那你只要和别的dumb jump支持的mode一样按下xref-find-definition就可以了,不需要考虑dumb jump是否支持/是否用dumb-jump-go。如果有一天不想用dumb jump了,你只要不再require它,而绑定xref-find-definition的部分不需要动,major-mode / 其它插件会继续设置合适的backend来让你愉快地跳转。

不过我现在js是用 js2的内置跳转 + xref-js2 了。优先跳到当前buffer的定义,不行再在项目里搜:

(use-package xref-js2
  :custom (xref-js2-search-program 'rg)
  :init
  (add-hook 'js2-mode-hook
            (lambda () (add-hook 'xref-backend-functions #'xref-js2-xref-backend nil t)))
  (defun jester/js2-jump-or-xref-definition ()
    "`js2-jump-to-definition' if we can, `xref-find-definitions' if can't or already at import statement."
    (interactive)
    (if (save-excursion
          (beginning-of-line)
          (let ((case-fold-search nil)) (search-forward "import " nil t)))
        (xref-find-definitions (xref-backend-identifier-at-point (xref-find-backend)))
      (condition-case err
          (js2-jump-to-definition)
        (xref-find-definitions (xref-backend-identifier-at-point (xref-find-backend))))))
  (general-define-key
   :states '(normal motion)
   :keymaps '(js2-mode-map)
   "g d" 'jester/js2-jump-or-xref-definition
   "g r" 'jester/xref-find-references-at-point))

(defun jester/xref-find-references-at-point ()
  "Find references for symbol at point."
  (interactive)
  (xref-find-references (xref-backend-identifier-at-point (xref-find-backend))))

搜到了xref-js2包,以前完全不知道有这玩意,感谢大佬的代码,好用~
