homebrew and fish shell

[thistlillo]

I have curiosity about the fish shell and homebrew. I asked this on the homebrew discussions but did not receive a definite answer.

I downloaded the Mac OS from the website and it is ~30MB in size.

Then I installed the (fish) shell using homebrew: it downloaded plenty of libraries and other support software. For example, openjdk (that was not installed). Openjdk is more than 300MB in size. However, if I look at the dependencies here https://github.com/fish-shell/fish-shell, it seems to rely upon a very limited set of libraries.

So question: who is packaging the cask "fish-shell"? How many MBs does this shell occupy?

If I had a normal-size HD I would not probably care, but with a 256GB MacBook Air, hundreds of MBs for the fish shell is quite a luxury I cannot afford.

fish-shell does not depend on OpenJDK. What command did you run exactly?

The fish-shell Homebrew recipe is here. You'll see it depends on cmake, ncurses, and pcre2; but not OpenJDK.

No no, I installed fish: brew install fish

May be it is related to this: Homebrew/discussions#57 and new dependencies were added to packages that got upgraded.

I use homebrew often, but I have never "studied" its working. It is the first time brew downloaded all that stuff when installing a simple package.

Check the actual fish formula, it does not have an openjdk dependency.

If openjdk got added onto your system, it's not because of that.

It is possible that another package you use gained an openjdk dependency. Fish doesn't have one, the main fish formula that you would typically get with brew install fish doesn't have one and I can't find a separate fish formula/cask/tap/... that has one, and it wouldn't make any sense because nothing about fish is written in java.

From your discussion, it seems you can run brew deps fish to see what the fish you installed depends on, and brew uses openjdk to see what depends on openjdk.

I will check it as soon as I get home tonight, where my Mac is, I cannot do it now.

When you run brew install foo it will sometimes run brew update --auto-update which can install a bunch of other stuff unrelated to foo. That's my guess as to what happened.

I checked the dependencies: as expected.

base ❯ brew deps fish 
ncurses
pcre2

both without further dependencies.

So may be it ran a --auto-update.

Thanks for your support.
