调研方向

从 rustup completions fish 的实现入手,检查它如何生成 fish 补全输出;issue 还建议添加 complete -c rustup -f。检查现有的 fish 补全输出测试或 fixture。完成的标准是:在 rustup 后按 Tab 会提示子命令,且不会列出文件或目录。

Problem

In fish shell, when you use an autocomple using tab you're getting directories and files alongside rustup subcommands.

As i know, rustup doesn't use any directories or files as arguments, so i recognize it as a bug

Steps
  1. Setup fish autocomplete. If you are on linux you can run rustup completions fish rustup > ~/.config/fish/completions/rustup.fish
  2. In fish write 'rustup '(leave one space char) and press tab. It should display subcommands and files and dirs
Possible Solution(s)

You can add 'complete -c rustup -f' in the beginning of fish autocomplete output. It will prevent display of files and directories.
I also tried to fix this in source code. I haven't find better solution than this:

I tried to find out how to make it a bit more beautiful with clap but no result.
