Emacs + Cider(Clojure)+自动完成:如何获取文档字符串？

Question

我正在尝试正确配置emacs来编写我的Clojure代码.我将这些Emacs配置基于这篇好文章.

但是,我确实更改了一些设置,比如他正在使用的主题等.我一直在检查自动完成(Eldoc？我不确定)在Clojure中显示函数的文档字符串,以及我自己的代码.

我想看一下截图中的文档:

但是,我无法显示"黄色"文档框.我不确定这是否是由于我的.emacs文件配置错误,或者是否是我必须使用的命令或...

这是我的.emacs档案:

(add-to-list 'custom-theme-load-path "~/.emacs.d/lib/noctilux-theme")

(require 'package):
  (add-to-list 'package-archives
    '("marmalade" . "http://marmalade-repo.org/packages/")
    '("melpa" . "http://melpa.milkbox.net/packages/"))

(setq mouse-wheel-progressive-speed nil) ;; don't accelerate scrolling

(setq mouse-wheel-follow-mouse 't) ;; scroll window under mouse

(setq scroll-step 1) ;; keyboard scroll one line at a time

根据@ syohex的评论更新

这是我在CLJ缓冲区中看到的内容:

在NREPL中,我确实看到了"v"而不是"d"(顺便说一下,这些字母是什么意思？).正如我在评论中所说,在NREPL中,我确实看到黄色框出现,然后当弹出窗口出现时,然后文档黄色框消失.在CLJ代码缓冲区中,黄色框永远不会打开.

最后更新

经过一些更多的测试,一切都按预期工作.当弹出窗口首次显示时,黄色框消失.但是,当我开始选择不同的选择时,它会重新出现在正确的位置.

此外,它开始在CLJ缓冲区工作,我看到字母"v"而不是"d",如上面的sreenshot中所示.也许我忘了启动NREPL,必须重新测试.

无论如何,一切都按预期工作.

nrepl-mode-hook、nrepl-interaction-mode-hook、nrepl-mode已废弃。您应该分别使用cider-mode-hook、cider-repl-mode-hook、cider-mode来代替它们。

并且您应该将ac-quick-help-delay值设置为大于0（例如0.5）。补丁如下。
