Running resque without Rakefile - ruby

Question

I have built my own job server, which is essentially a private gem, built as a wrapper around resque.
(I am not running this in a Rails environment)
Everywhere I look, it seems like the documented/recommended way to start the workers, is with something like this:
$ QUEUE=* rake resque:work
Which means that it must be executed in a folder where the Rakefile exists.
I am looking for a way to start it without a Rakefile.
What I have learned so far:
I have looked through the issues, maybe someone asked a similar question.
I have looked through the wiki, and specifically the FAQ.
I know I can probably create my own "bin" to run it without rake, by analyzing the tasks file.
I saw that resque installs a resque binary, but it only seems to provide limited functionality, like removing and listing a worker, but not starting.
My current workaround is that my gem's binary is doing chdir to the gem's folder before running (and this folder has a Rakefile), like the code below.
def start_worker
ENV['QUEUE'] = '*'
Dir.chdir gemdir do
exec "rake resque:work"
end
end
def gemdir
File.expand_path "../../", __dir__
end
Appreciate any nudge in the right direction.

Answer 1

The current solution I have worked up for this:
def start_worker
interval = 5
queue = '*'
ENV['QUEUE'] = queue
worker = Resque::Worker.new
Resque.logger = Logger.new STDOUT
Resque.logger.level = Logger::INFO
## this is not yet implemented in 1.26.0, keeping here as a reminder
# worker.prepare
worker.log "Starting worker"
worker.work interval
end
Which is an adaptation of the code from the rake task
For reference, I also opened a github issue, in the off chance that someone else also needs such functionality.

Answer 2

I having created a script to create demon worker processes using following worker starting API.
def start_worker(id)
ENV['QUEUE'] = #queues || "*"
ENV['PIDFILE'] = pid_file(id)
ENV['JOBS_PER_FORK'] = #jobs_per_fork || "1000"
ENV['BACKGROUND'] = 'true'
ENV['TERM_CHILD'] = 'true'
#debug ? ENV['VVERBOSE'] = 'true' : ENV['VERBOSE'] = 'true'
begin
worker = Resque::Worker.new
rescue Resque::NoQueueError
Resque.logger.error "No queue is set for worker_id = #{id}"
end
worker.prepare
worker.log "Starting worker #{self}"
worker.work(5) # interval, will block
end
