# brew-bundle.rb # brew-bundle.rb
#
# Usage: brew bundle [path] def usage
# puts <<-EOS.undent
# Looks for a Brewfile and runs each line as a brew command. Usage: brew bundle [path]
#
# brew bundle # Looks for "./Brewfile" Looks for a Brewfile and runs each line as a brew command.
# brew bundle path/to/dir # Looks for "path/to/dir/Brewfile"
# brew bundle path/to/file # Looks for "path/to/file" brew bundle # Looks for "./Brewfile"
# brew bundle path/to/dir # Looks for "path/to/dir/Brewfile"
# For example, given a Brewfile with the following contents: brew bundle path/to/file # Looks for "path/to/file"
# tap foo/bar
# install spark For example, given a Brewfile with the following content:
# install formula
# Running `brew bundle` will run the commands `brew tap foo/bar`
# and `brew install spark`. Running `brew bundle` will run the command `brew install formula`.
NOTE: Not all brew commands will work consistently in a Brewfile.
Some commands will raise errors which will stop execution of the Brewfile.
Example that outputs an error:
tap my/tap # fails when my/tap has already been tapped
In this case use the full formula path in the Brewfile instead:
install my/tap/formula # succeeds even when my/tap has already been tapped
EOS
exit
end
usage if ARGV.include?('--help') || ARGV.include?('-h')
path = 'Brewfile' path = 'Brewfile'
error = ' in current directory' error = ' in current directory'
