如何将RVM信息显示到emacs模式行？

Question

嘿伙计们，我需要在emacs模式行中看到我的ruby版本和gemset名称。你知道怎么做吗？

Answer 1

看看rvm.el。我提供了许多功能，使得使用Emacs的RVM更加愉快。

Answer 2

我试过但我不能自定义mode-line字符串，所以我自定义了所有字符串。

;; modeline
(defun branch-name ()
  (when vc-mode
    (concat "\ue0a0 " (substring vc-mode 5))
    ))

(defun current-ruby ()
  (when vc-mode
    (replace-regexp-in-string "\n$" "" (shell-command-to-string "~/.rvm/bin/rvm-prompt"))
))

(setq-default mode-line-format
      (list
       "[" mode-line-modified "]"
       "  "
       "%b"
       "  |  "
       'mode-name
       "  |  "
       '(:eval (projectile-project-name))
       " "
       '(:eval (branch-name))
       "  |  "
       '(:eval (current-ruby))
       "  |  "
       "%p (%l,%c)"
       ))
