Ruby: calling method within another method's conditional statement - json

Question

I'm trying to call the method print_json within a conditional statement that is contained in another method named list_trends. I did this becauese my code was starting to look too nested. However I get an error when I run that says:
syntax error, unexpected tSTRING_BEG, expecting keyword_do or '{' or '('
...i_key]) ? print_trends : puts "Invalid API Key, operation ab...
Here is my code:
#!/usr/bin/ruby
require 'thor'
require 'json'
class ListTrends < Thor
desc "list trends", "list out trends from JSON file"
option :api_key, :aliases => "--api-key", :type => :string, :required => true
def print_json
json = File.read('trends_available.json')
trends_hash = JSON.parse(json)
trends_hash.each do |key|
key.each do |k,v|
puts "Trend #{k}: #{v}"
end
puts ""
end
end
def list_trends
re = /^(?=.*[a-zA-Z])(?=.*[0-9]).{8,}$/
if options[:api_key]
if re.match(options[:api_key]) ? print_json : puts "Invalid API Key, operation abort..."
end
end
end
ListTrends.start(ARGV)

Answer 1

This
if options[:api_key]
if re.match(options[:api_key]) ? print_json : puts "Invalid API Key, operation abort..."
end
Should just be
if options[:api_key]
re.match(options[:api_key]) ? print_json : puts "Invalid API Key, operation abort..."
end
Though I would prefer:
if options[:api_key]
if re.match(options[:api_key])
print_json
else
puts "Invalid API Key, operation abort..."
end
end
Or if you must put it on one line:
if options[:api_key]
if re.match(options[:api_key]) then print_json else puts "Invalid API Key, operation abort..." end
end
