❯ brew info go@1.24
==> go@1.24 ✔: stable 1.24.13 (bottled) [keg-only]
Open source programming language to build simple/reliable/efficient software

Deprecated because it is not supported upstream! It will be disabled on 2027-02-11.

License: BSD-3-Clause
==> Caveats
go@1.24 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.

If you need to have go@1.24 first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/go@1.24/bin:$PATH"' >> ~/.zshrc

The following go@1.24 executables are shadowed by other linked Homebrew commands:
  go (shadowed by /opt/homebrew/bin/go from go)
  gofmt (shadowed by /opt/homebrew/bin/gofmt from go)
Running these by name will not invoke the version provided by Homebrew.
Run `brew link go@1.24` to switch the active version to this keg.

/opt/homebrew/Cellar/go@1.24/1.24.13_1 (14,126 files, 256.2MB)

and

go@1.24 (1.24.13_1) *

both output the same information.

I think if we want to highlight other versions it should avoid duplication.

Also as a general note @HaraldNordgren: I'm getting concerned that we may make brew info less useful if we just keep adding information without removing any. Thoughts?

HaraldNordgren · 2026-05-12T09:54:00Z

/opt/homebrew/Cellar/go@1.24/1.24.13_1 (14,126 files, 256.2MB)

and

go@1.24 (1.24.13_1) *

both output the same information.

I don't quite follow this? Do you mean the star for a linked formula, it's quite hidden imo, not sure how many users look here. It's there for a formula without any siblings as well. So for me I would consider dropping it:

Could be true! Even if I'm spraying PR's at the moment, these are things I have had in the back of my head for the 10 or so years I've been using Homebrew and teaching my team to use brew, so not just randomly adding stuff 🤗

HaraldNordgren · 2026-05-12T09:57:20Z

Or do you mean the location of the keg itself? Yes, that also seems quite specific and not necessarily useful unless the user wants --verbose.

/opt/homebrew/Cellar/go@1.24/1.24.13_1 (14,126 files, 256.2MB)

It doesn't tell me if it's linked or not.

I mean that this section will output multiple kegs for e.g. go so, if we want to output e.g. some go@another.version kegs: it might make sense to have them "nearby" and in a similar format.

Ok good to know 👍🏻

@MikeMcQuaid Ah, so you mean collapse the new ==> Installed versions section and instead adding all the version paths up here?

/opt/homebrew/Cellar/go@1.24/1.24.13_1 (14,126 files, 256.2MB)

Maybe, but not necessarily clearer for me as a user. If so, we should add some explanatory text as well!

MikeMcQuaid · 2026-05-12T11:21:18Z

the new ==> Installed versions section and instead adding all the version paths up here?

Yeh. Or we make that part of the installed versions section and display similar information. I'd like to avoid repetition between sections that are relatively far apart from one another.

@MikeMcQuaid Moving it down to the installed versions section would look nicer I think, the upper section is quite crowded. However, one complication is that I was not going to show that section when there are no siblings. We need to have a solution that works for any formula.

Yeh. I think the "installed versions" language makes sense even for the current output? what do you think?

HaraldNordgren · 2026-05-12T12:30:20Z

@MikeMcQuaid Updated, looks much nicer! I renamed the section to "Installed" so it wouldn't look weird for formulae without siblings:

@MikeMcQuaid Here is an output that I like.

Got rid of "Not installed" line, the header already tells us this
