Shell ZSH挂起打开的应用程序选项卡自动完成

我经常使用命令

open-a

在Mac上打开应用程序。最近我还一直在使用制表符自动完成来完成我的命令。例如，我在写了

open-a

或

open-a Safa

之后尝试这样做，但当我点击tab时，zsh挂起，我无法在窗口中键入任何其他内容。这也没有提供应有的自动完成选项。我在Terminal和iTerm2中都试过了，但问题仍然存在

我使用的是zsh 5.7.1。我的电脑上也安装了Oh My Zsh

为了以防万一，这是我的

.zshrc

文件：

# export PATH=$HOME/bin:/usr/local/bin:$PATH

ZSH_THEME="spaceship"
#"robbyrussell"

# Set list of themes to pick from when loading at random

如何修复此问题并启用自动完成功能，以便使用zsh打开应用程序，就像在zsh的其他地方一样？

这实际上是一个macOS错误！问题在于苹果自己的

open

compdef完成脚本

在过去，

open-a

完成速度很快，因为autocomplete脚本使用Spotlight索引进行超快速的应用程序获取。您可以在此处找到相关脚本：

/usr/share/zsh/5.7.1/functions/\u retrieve\u mac\u apps

（参考同一目录中的

\u open

脚本）

但是，要检查Spotlight搜索索引是否存在，它将查看文件

/.Spotlight-V100

是否存在。在某些macOS更新中，用户文件的聚光灯索引移动到此处：

/System/Volumes/Data/.Spotlight-V100

，但自动完成脚本未更新！当它认为不存在聚光灯索引时，它会退回到一个非常缓慢的手动应用程序列表

具体而言，错误在于此检查：

...
      if [[ -d /.Spotlight-V100 ]]; then
        # / is indexed to use Spotlight
         retrieve=_mac_apps_spotlight_retrieve
       else
         # Fall back to the old way
         retrieve=_mac_apps_old_retrieve
       fi
       zstyle ":completion:*:*:${service}:commands" search-method $retrieve

然后，缓慢的实现完成了这个神秘的shell fu。当我进行实验时，它似乎永远挂在我身上

 _mac_apps_old_retrieve () {
   # Get directories which may contain applications
   typeset -aU app_dir
   if [[ -z "$app_dir" ]] && \
     ! zstyle -a ":completion:${curcontext}:commands" application-dir app_dir
   then
     typeset -a app_dir_stop_pattern
     app_dir_stop_pattern=( "*.app" "contents#" "*data" "*plugins#" "*plug?ins#" "fonts#" "document[[:alpha:]]#" "*help" "resources#" "images#" "*configurations#" )
     typeset app_dir_pattern
     app_dir_pattern="(^(#i)(${(j/|/)app_dir_stop_pattern}))"
     app_dir=( ${^app_dir_root}/(${~app_dir_pattern}/)#(N) )
   fi
...

可悲的是，由于这个bug是macOS本身的一部分，所以该文件受系统完整性保护，因此修复起来非常烦人。您可以复制它，修复错误，并用您的固定版本替换open的compdef。希望苹果最终能在大苏尔解决这个问题

当我点击tab时，zsh挂起

-您等了多长时间？你试过ctrl+c吗？@KamilCuk它会无限期地运行而不需要干预（在关闭终端并重试之前，我最多离开它15分钟）。Control+c显示消息“Killed by signal in_mac_apps_old_retrieve after 2s”，然后继续单击enter，它只表示找不到具有缩短名称的应用程序（这不是全名，因为我正在寻找自动完成的应用程序）@NoahWilder：我想这只是在

open

的上下文中，也就是说，当你做一个简单的

cat

时，你看不到这种效果？@1934428这只发生在

open-a

的上下文中。

open

和

cat

都能按预期执行。这并不能回答您明确的问题，但应该解决您的使用案例——VSCode附带了命令行工具，您可以从命令对话框安装，该对话框将

code

添加为您可以从命令行使用的命令。要达到上述目的，只需键入

code.

即可在VSC中打开当前目录！
