Non-interactive `chruby-exec` fails with `zsh:1: command not found: chruby`

[amomchilov]

Description

chruby.sh is typically sourced from ~/.zshrc, which is only run in interactive shells. For non-interactive shells, chruby-exec calls zsh without the -i:

https://github.com/postmodern/chruby/blob/67192019ccf885b23ffc25c7f40ed64be8d2832e/bin/chruby-exec#L41

This causes the ~/.zshrc to never be sourced, and thus, for chruby to be unavailable.

Steps To Reproduce

Steps to reproduce the bug:

1. Install the latest release (0.39.0 right now) with brew install chruby

2. Run chruby-exec with a non-terminal STDIN. E.g. with:

   echo "abc" | chruby-exec "ruby-3.3.0" -- ruby --version
   

Expected Behavior

Run the command successfully, (in this example, ruby --version). It works correctly if you drop the echo "abc" |:

$ chruby-exec "ruby-3.3.0" -- ruby --version
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [arm64-darwin23]

This works fine because it hits this other branch, which include -i and runs ~/.zshrc:

https://github.com/postmodern/chruby/blob/67192019ccf885b23ffc25c7f40ed64be8d2832e/bin/chruby-exec#L40

This also works on the latest master branch, so it looks like it's a packaging/release issue:

$ brew uninstall chruby && brew install chruby --head
$ echo "abc" | chruby-exec "ruby-3.3.0" -- ruby --version
ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [arm64-darwin23]

Actual Behavior

$ echo "abc" | chruby-exec "ruby-3.3.0" -- ruby --version
zsh:1: command not found: chruby

Notes

https://github.com/postmodern/chruby/releases/tag/v0.3.9 was release in April 19, 2023, but for some reason, it doesn't include this change to chruby-exec from 2014. I confirmed this in 2 ways:

1. Inspecting bin/chruby-exec of the chruby-0.3.9.tar.gz downloaded right from the release page
2. Inspecting /opt/homebrew/bin/chruby-exec installed by homebrew.

It looks to me like the release process just didn't package up this file correctly.
