Tests are failing. Might get a colleague that has a Mac to look into why if I can - but test failure needs resolving before PR can be merged. |
All we care about is that GNU grep is available, which could've been installed in a number of ways, not just via Homebrew.

Hey @Zordrak, I think I've fixed the issue, see the commit message for the details. |

When we find a brew-installed grep, we create an alias from ggrep to grep, but an alias can't be defined and used in the same parsing unit, so we exit early instead. See: https://www.shellcheck.net/wiki/SC2262

I'm working on a project that uses nix as a package manager through a flake file. I can add tfenv through a custom derivation, which can include the required gnugrep dependency in the definition.
But the project assumes that the GNU version would be installed with Homebrew, which might not be installed at all.
Since all we care about is that GNU grep is available, we should use
grep --versioninstead.
