I recently needed to install an older version of hugo via brew but ran into some issues:
$ brew install hugo@0.57.1
...
Error: No available formula with the name "hugo@0.57.1"
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
git -C "$(brew --repo homebrew/core)" fetch --unshallow
...
Now the brew repository is rather large, so getting the complete history when all I need is a single package just seemed unreasonable.
The solution was surprisingly easy:
Browse to the brew formula for the package, in my case it was https://github.com/Homebrew/homebrew-core/commits/master/Formula/hugo.rb
Click on the <> link to browse the repository at this point in history. Next is to browse once again to the formula and copy the URL for passing directly to brew:
brew install https://github.com/Homebrew/homebrew-core/blob/b3375784ad033442c182caac5240fbe4d0a3d581/Formula/hugo.rb
Done! 👍🏻
