After upgrading existing kegs, we now search and upgrade their dependents as well. If any are detected that have broken linkage, they are reinstalled from source. If there are any formulae in the dependents tree that are pinned, they are only reinstalled if they're not outdated; in all cases, a suitable message is printed detailing the kegs that will be acted upon.
Library
This directory contains all the code run by the official brew
and brew cask
commands in Homebrew
and all formulae (package descriptions) in taps (repositories containing formulae) in Taps
subdirectories.
