A Little Pow Helper

If you are a Ruby developer on MacOS X, you probably love Pow as much as I do. While skimming the fine manual today, I noticed section 3.2, “Reading the Current Configuration”, which explains that you can query Pow’s config and status via simple HTTP requests:

Query Pow’s statusPow manual
1

curl -H host:pow localhost/status.json

Since I know I’d probably forget that sooner than later, I immediately wrapped it up in a small script, which I called pow-show and put in ~/bin:

~/bin/pow-show
1

10

#!/usr/bin/env ruby

require 'json'

unless %w(status config).include?(ARGV[0])
  puts "Usage: #{File.basename($0)} status|config"
  exit 1
end

jj JSON.parse(`curl -s -H host:pow localhost/#{ARGV[0]}.json`)

Here’s some example output:

pow-show status

  "pid": 802,
  "version": "0.3.2",
  "requestCount": 134
}

Maybe that’s useful for someone else too.
