Should we handle different types of formulae? Is there an existing pattern for how you'd like this handled?

I think it's fine to just support brew for now and people can extend it later if desired. As long as it's documented it can raise UsageError which will print the help text.


# read the relevant Brewfile
parsed_entries = Bundle::Dsl.new(Brewfile.read(global: global, file: file)).entries

# check each of the entries in the specified Brewfile
parsed_entries.each do |entry|
# raise an error if the entry already exists in the Brewfile
# this could also be a noop, or print a friendly message
raise RuntimeError if entry.name == name

Yup, friendly message would be nice.

end

# need some help / pointers here
# is it possible to use Bundle::Dsl to create an in memory representation
#of the brewfile that we read, add an entry and then dump that back to the file?

This is where I could use the most help

This is the existing dumper code for this:

homebrew-bundle/lib/bundle/brew_dumper.rb

Lines 18 to 39 in 034459d

def formulae
@formulae ||= begin
@formulae = formulae_info
sort!
end
end
def dump(describe: false, no_restart: false)
requested_formula = formulae.select do |f|
f[:installed_on_request?] || !f[:installed_as_dependency?]
end
requested_formula.map do |f|
brewline = ""
brewline += desc_comment(f[:desc]) if describe && f[:desc]
brewline += "brew \"#{f[:full_name]}\""
args = f[:args].map { |arg| "\"#{arg}\"" }.sort.join(", ")
brewline += ", args: [#{args}]" unless f[:args].empty?
brewline += ", restart_service: true" if !no_restart && BrewServices.started?(f[:full_name])
brewline += ", link: #{f[:link?]}" unless f[:link?].nil?
brewline
end.join("\n")
end

It's probably possible to do that but you may have more luck trying to inject your desired formulae state into the existing logic (overriding @formulae somehow).
