If that’s too long for you, Homebrew is smart enough that abbreviating --formula in a non-ambiguous way like brew ls --fo | grep will also work

Step 1

Check you have already Install the Xcode. Run the below command in your terminal

/usr/bin/xcodebuild -version

It will print the below sample output
Xcode 12.3
Build version 12C33

Step 2

Now Open Xcode
Select preferences
Select location tab
Now in command Line Tool select your Xcode version from dropdown menu

Step 3

In terminal run below command

/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”

Note : if you have M1 Chip Mac run the below command, close terminal and open the terminal again

echo “export PATH=/opt/homebrew/bin:$PATH” >> ~/.zshrc

Here’s my output

It seems that there are still issues. After that, brew update still complaints about the shallow clone, and the unshallow command outputs the same as before.

brew update
Error:
  homebrew-cask is a shallow clone.
To `brew update`, first run:
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow
This command may take a few minutes to run due to the large size of the repository.
This restriction has been made on GitHub's request because updating shallow
clones is an extremely expensive operation due to the tree layout and traffic of
Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you
automatically to avoid repeatedly performing an expensive unshallow operation in
CI systems (which should instead be fixed to not use shallow clones). Sorry for
the inconvenience!

After that unshallow gives this:

git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow

There’s a hash referred there “a09435a3aedccba853a45c8af850c5777a389ce9”, I found it in the commit below, not sure if that helps resolving this.

Any pointers?

Thanks!

Of course, that’s neither here nor there. I got the same message on my multiple Macs that you did, and did what it said to do. Easy peezy.

Danrancan:

To be clear, The Cask auto-updates? or the Application it self autoupdates with the “autoupdate” selection turned on in the app?

The software auto updates, not the cask. Indeed

Is there a version of google chrome in homebrew that is built from source?

No, we don’t ship a source build of chrome. You can maintain one in a tap though.

How can I force homebrew to only download apps that were built from source, or at the very least, warn me when they are not built from source?

Don’t use casks, those are never build from source.

SMillerDev:

GitHub - Homebrew/homebrew-bundle: 📦 Bundler for non-Ruby dependencies from Homebrew, Homebrew Cask and the Mac App Store.

I will look into this as soon as I convert to zsh on mac (very soon).
Thanks for the answer!

SMillerDev:

The cask doesn’t define a checksum, most likely because it auto updates and therefore the checksum would be constantly out of date (since the download doesn’t specify a version)

I have no idea what it does, or its purpose is, and would like to figure out what homebrew application installed it, what its purpose is, and how to uninstall it and all related applications. Any help is much appreciated here!

Thanks in advance!

xareelee:

How can I parse the version number in the DSL-formula ruby file without using brew CLI commands? Does it parse version number from url ?

Yes. Also note that brew info has a --json option that should greatly help with parsing formula details.

Try looking in version.rb.

Because for casks, the version is used to determine the download URL:

cask "thunderbird" do
  version "78.6.0"
  url "https://ftp.mozilla.org/pub/thunderbird/releases/#{version}/mac/#{language}/Thunderbird%20#{version}.dmg",...

whereas the reverse is true for formulae. A Cask maintainer would be able to speak definitively on this, but I suspect this disparity is due to the general nature of the download URLs in each case:

A significant number of casks have versionless URLs like https://dl.google.com/chrome/mac/universal/stable/GGRO/googlechrome.dmg, that come from literally anywhere and can change at any time independent of each other, so writing URL-parsing code for this is probably a lost cause.

In contrast, most formulae download source tarballs from a limited number of well-known sites (e.g. GitHub) with well-known URL formats that include version info, so the URL-parsing logic is both straightforward and generally stable.

In short, version overrides are needed fairly rarely with formulae, but fairly often with casks, so I can understand why the decision was made to make version mandatory for casks.

class Hello < Formula
    version "1.2.3"
    ...
end

I read the source code of file info.rb, named_args.rb, Formulary.rb, and software_spec.rb, and did not find a clue.

How can I parse the version number in the DSL-formula ruby file without using brew CLI commands? Does it parse version number from url?

Furthermore, why brew formulae DSL don’t have this tag for version number, but cask do?

Try a big tech team that push a lot of code every day, which then runs in a CI workflow.
Each of those require brew update, which can take anything between 2-6 minutes extra.

Those add up to many hours of extra cpu-usage every month, which costs a lot of money

I’m wondering why it couldn’t work like npm or rubygems. They install the latest available version available, without taking minutes to pre-update.

Danrancan:

This seems to imply that homebrew isn’t able to verify my google chrome download with a checksum, and my download could potentially be modified by a mitm attack.

The cask doesn’t define a checksum, most likely because it auto updates and therefore the checksum would be constantly out of date (since the download doesn’t specify a version)
https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/google-chrome.rb

Only download software that is build from source and/or don’t download anything that auto updates.

Thanks!

This seems to imply that homebrew isn’t able to verify my google chrome download with a checksum, and my download could potentially be modified by a mitm attack.

Why is this happening, and how do I ensure that homebrew checksums and verifies all downloads so that my downloads are verified and secure?

oguzhanvarsak:

Big Sur, 11.1

git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

my terminal just hangs.

When you hit <Ctrl-C>, do you get the shell prompt back? If so, it didn’t hang; unshallowing requires downloading the entire repo, which is fairly large.

You can set the GIT_TRACE_CURL environment variable to get a trace of what’s being downloaded (it’s VERY verbose, but at least you’l know something’s happening):

GIT_TRACE_CURL=1 git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

If you didn’t get a “Error: homebrew-cask is a shallow clone”, why are you running this command?

git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

or

git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask" fetch --unshallow

did not fix the problem. When I use the first one, my terminal just hangs.

Using the second one throws this error :

fatal: --unshallow on a complete repository does not make sense

To brew update , first run:
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow

[target.x86_64-unknown-linux-gnu]

and it compiled. You can have a try.

Could someone explain whats going on here and how to fix it, with a possible explantation of how it may have happened? Last thing I remember doing was screwing around with git, but im not sure what i did, and/or if its related.

Any help is apprecited.

brew create https://gitlab.cern.ch/gaudi/Gaudi/-/archive/v35r0/Gaudi-v35r0.tar.gz  --set-name gaudi

I tried to install it right after and it worked. After some modification to the formula, I obtain the following message when I tried to install it using brew install gaudi

==> Searching for similarly named formulae...
This similarly named formula was found:
gaudi
To install it, run:
  brew install gaudi
Error: No available formula or cask with the name "gaudi".
==> Searching taps on GitHub...
Error: No formulae found in taps.

Any idea why this is happening ?
