请问emacs显示变量函数的是用imenulist吗？怎么加上icon呢？

taigacute · 2019 年8 月 5 日 03:21

感觉很低效啊，还是没看doc和详细的README来的快。。有点不适应。

cireu · 2019 年8 月 5 日 03:33

那就看README，一般都有readme，不过包管理倒不会自动拉取readme

seagle0128 · 2019 年8 月 5 日 05:54

imenu-list本身没有提供配置功能，你可以给作者提需求。

看了下代码，其实很简单，自己修改下imenu-list--insert-entry应该就行了。默认entry 是写死加上+的。

如果是使用 lsp，默认就有lsp-ui-imenu，会漂亮很多。

taigacute · 2019 年8 月 5 日 05:56

我用了lsp-ui-imenu 也很丑啊。。也没有icon

seagle0128 · 2019 年8 月 5 日 05:58

不是只有 icon 才是美的，你让用 terminal 的怎么活？如果一定要，自己加上就行了啊。Centaur 大部分都是自定义的，后来才进入上游并且有配置的。

taigacute · 2019 年8 月 5 日 08:21

terminal也可以的 nerdfonts 我vim都可以啊

seagle0128 · 2019 年8 月 5 日 15:13

emacs也可以加上 icon，terminal 也可以用。问题是远程 ssh 的服务器就没辙了，大多数工作场景都如此，除非用 tramp。

cireu · 2019 年8 月 5 日 16:30

nerdfonts 缺字，效果没all-the-icons用的那几个字体效果好

seagle0128 · 2019 年8 月 6 日 14:27

对，nerd fonts 缺少很多 icon。我也创建了一个icons-in-terminal.el，可以在 GUI 和 Terminal 下使用，跟 all-the-icons 方法一模一样。

finalpatch · 2019 年10 月 30 日 13:52

All the icons 用了几天删了，主要是因为图标宽度不一，导致后续文字不能对齐。我有强迫症，不对齐无法忍

cireu · 2019 年10 月 31 日 23:41

突然发现有人和我纠结这个看源码的问题……行吧，我想我得仔细解释下。原来Elisp的打包标准是每个包要有一个;;; Commentary的长说明注释，但为了方便，又规定当有README文件的时候，可以不用写;;; Commentary（README用markdown，org写也行，本质没变），另一方面README可以被Github显示，所以大家都写README。然而melpa拉取包的默认pattern并没有包含README文件。结果导致只有代码被拉到本地，包的详细说明只能自己上仓库看。

不过MELPA的初审是要求所有函数都要有docstring，所以大部分情况看包入口函数的docstring就能满足需求了（除非那个人偷懒写得特别语焉不详，然而MELPA审核会拒绝接受）

可以对齐的，你没找到方法而已。

seagle0128 · 2019 年11 月 5 日 13:30

现在treeamcs和lsp-treemacs都支持imenu icon 了

zhouchongzxc · 2019 年11 月 5 日 13:39

喊你去看源码

manateelazycat · 2020 年1 月 18 日 16:07

对齐的方法是啥？求分享

seagle0128 · 2020 年1 月 19 日 03:05

简单说就是用TAB,并设置width为1

manateelazycat · 2020 年1 月 19 日 03:54

有啥代码可以抄的吗？最近比较流行抄作业。

谢谢，我自己在 snails 代码里面按照你的方法试验，感觉没有对齐啊，只是增加了 tab 字符

(defun snails-wrap-buffer-icon (buf)
  "Wrap display name with buffer icon, use for buffer search backend."
  (if (featurep 'all-the-icons)
      (progn
        (setq-local tab-width 1)
        (format "%s\t '%s'"
                (with-current-buffer buf
                  (all-the-icons-icon-for-buffer))
                (string-trim-left (buffer-name buf))))
    (buffer-name buf)))

(defun snails-wrap-file-icon (file)
  "Wrap display name with file icon, use for file search backend."
  (if (featurep 'all-the-icons)
      (progn
        (setq-local tab-width 1)
        (format "%s\t %s"
                (all-the-icons-icon-for-file file :height 1)
                (string-trim-left file)))
    file))

(defun snails-wrap-file-icon-with-candidate (file candidate &optional no-trim)
  "Wrap display name with file icon, use for file search backend."
  (if (featurep 'all-the-icons)
      (progn

我没有使用snails，如果还不行用overlay肯定可以解决
