Installing previous versions of formulae
The supported method of installing specific versions ofsome formulae is to see if there is a versioned formula (e.g. gcc@7) available. If the version you’re looking for isn’t available, consider using brew extract.
$ brew install emacs-mac. If you using cask. Brew install -cask emacs-mac or brew install -cask emacs-mac-spacemacs-icon. To disable this tap, please. $ EMACS=$(which emacs) brew install `mu` -with-emacs -HEAD The only problem is which emacs finds the emacs in /usr/bin which is too old. So, I moved the old Emacs to /usr/bin/emacs-backup and symlinked in the newer Emacs that is actually the newer version. 🍻🐧 Core formulae for the Homebrew package manager on Linux - Homebrew/linuxbrew-core.
Quickly remove something from /usr/local
This can be useful if a package can’t build against the version of something you have linked into /usr/local.
And of course, you can simply brew link <formula> again afterwards!

Pre-downloading a file for a formula
Sometimes it’s faster to download a file via means other than thosestrategies that are available as part of Homebrew. For example,Erlang provides a torrent that’ll let you download at 4–5× the normalHTTP method.
Download the file and drop it in ~/Library/Caches/Homebrew, butwatch the file name. Homebrew downloads files as <formula>-<version>.In the case of Erlang, this requires renaming the file from otp_src_R13B03 toerlang-R13B03.
brew --cache -s erlang will print the correct name of the cacheddownload. This means instead of manually renaming a formula, you canrun mv the_tarball $(brew --cache -s <formula>).
You can also pre-cache the download by using the command brew fetch <formula> which also displays the SHA-256 hash. This can be useful for updating formulae to new versions.
Installing stuff without the Xcode CLT
This imports the brew environment into your existing shell; gem will pick up the environment variables and be able to build. As a bonus brew’s automatically determined optimization flags are set.
Install only a formula’s dependencies (not the formula)

Hiding the beer mug emoji when finishing a build
This sets the HOMEBREW_NO_EMOJI environment variable, causing Homebrewto hide all emoji.
The beer emoji can also be replaced with other character(s):
