# @file Homebrew / Xcode Tools Installation
|
|
# @brief Ensures Xcode tools are installed on macOS and ensures Homebrew is installed on either Linux or macOS
|
|
# @description
|
|
# This script ensures macOS has tools like `git` by installing the Xcode command-line developer tools if they are
|
|
# not already installed. Then, on both Linux and macOS, it ensures Homebrew is installed.
|
|
#
|
|
# It also tries to perform a system update and there may be some manual work required since it is not possible
|
|
# to completely automate the system update process for macOS.
|
|
#
|
|
# ## Environment Variables
|
|
#
|
|
# * `NO_RESTART` - Set this variable to skip restarts triggered by system updates on macOS
|
|
#
|
|
# ## Homebrew Requirement
|
|
#
|
|
# Install Doctor relies on Homebrew for many tools that are currently only available via Homebrew. Removing the dependency
|
|
# would be a nice-to-have but there are currently no plans for supporting systems without Homebrew installed.
