安装后启动失败。以下是debug-init打开后的输出。系统：ubuntu22.04@wsl2

另外，之前曾经成功使用过。但是dictionary-lookup-definition一直不能用，说没有definition.不知如何解决？

dictionary-lookup-definition 是 Emacs 内置的的一个词典，我也不太确定这是个什么问题。推荐使用其他的自用词典。

似乎不是dictionary-overlay的问题，是系统自带的dictionary-lookup-definition没配置好？你直接把光标放在一个词上，调用命令dictionary-lookup-definition可以用么？

@ginqi7 不知道是不是和你第一次使用时的情况是一样的？ On Dec 9, 2022, 01:00 -0500, xianbang2021 @.***>, wrote:

@xianbang2021 我记得dictionary-lookup-definition是需要配置的，我只使用过一次，已经忘了怎么调试了。现在用的懒猫的popweb-dict-**.el 系列。我以前写这几行代码的时候，测试的是youdao-dictionary, 截图里的几个你都可以试试。各种第三方词典写的能够获取光标下word的功能都能使用，一般命令名字都是 **-at-point。

dictionary-lookup-definition 是 Emacs 内置的的一个词典，我也不太确定这是个什么问题。推荐使用其他的自用词典。

您好，我去源代码那边把dictionary-overlay-lookup-with 相关的全部注释掉了。可以启动和正常使用。 （比较奇怪的是：dictiionary-lookup-definition我手工调用是可以正常查询的，我使用的是dictd)

想请教一下：

1. dictionay-overlay-lookup-with 欲调用的函数，和那个translator（local，sdcv等）是什么关系？
2. local指的是什么查询程序？我在wsl2里边安装了sdcv，词典是简明edict。dictionary-overlay实际使用中，overlay上体现的查询结果和我sdcv手工查询的结果似乎不太一致。所以有点疑惑。

[ginqi7]

dictionay-overlay-lookup-with 欲调用的函数，和那个translator（local，sdcv等）是什么关系？

dictionay-overlay-lookup-with 是作为查询单词详情的词典用的（如果你没有自己日常用的词典可以用它兜底，推荐你使用日常的Emacs词典查询详情）。其他的 translator 是用来展示括号里的解释。

local指的是什么查询程序？

local 是只本地缓存，会有一个 dictionary.json 的用户文件，会保存你查询过的单词的含义，下次直接展示它。

查询结果和我sdcv手工查询的结果似乎不太一致

这里的 sdcv 并不是调用你本机安装的sdcv。而是dictionary-overlay 自己内置了一个 sdcv 支持的词典，使用该词典查询的。
