Rye+Fish: Add Shims to Path

[hhstore]

Add Fish Env:

• https://rye-up.com/guide/installation/
• The rye documentation does not provide environment variable settings for fish shell, I read the env file, supplementing the following available setting methods.
• If you are using fish, you can set the environment variables as follows.
• Alternatively, it can be updated to rye's documentation.

fix for fish shell:

• add to ~/.config/fish/conf.d/env.fish:

# python + rye: $HOME/.rye/shims
set -gx PATH "$PATH:$HOME/.rye/shims"

Do you know if there is a way for fish to source posix shell files? (eg .rye/env)

[hhstore]

• @mitsuhiko I looked it up and fish shouldn't support source posix shell files by default, but found a plugin foreign-env. Using this plugin, it can be solved.
• In addition, I found that rustup encountered the same problem, and the solution given by the community was the same as my first approach. There is reason to believe that the community did not find a better way.

another solution:

• install a fish plugin: foreign-env with oh-my-fish

omf install foreign-env

• edit ~/.config/fish/config.fish

# fenv + rye: source "$HOME/.rye/env"
if status --is-interactive
  fenv source "$HOME/.rye/env"
end
# rye end

• I've tested it and it works fine.

• PATH support doesn't work for fish shell rust-lang/rustup#478 (comment)
  • rustup set env for fish shell.

Sounds like the best thing would be to add this to the docs:

set -Ua fish_user_paths $HOME/.rye/shims

Maybe print that out as an alternative if fish is detected in the installer.
