Ruby 2.0 + rails 4.0
I want to show weather-feed on the public site, is there any gem which will show the weather according to the city name ?
without any registrations and charges.
Any suggestion ?
Why? write your using nokogiri and yahoo weather api!
it is quite a way try to do something myself and know more than using someone else's
For example:
require "nokogiri"
require "open-uri"
link = "http://weather.yahooapis.com/forecastrss?w=2123260&u=c" #2123260 this code of my city
data = Nokogiri::XML(open(link))
data.xpath("//item//yweather:condition")[0].to_s
#=> "<yweather:condition text=\"Cloudy\" code=\"26\" temp=\"-6\" date=\"Tue, 10 Dec 2013 3:30 pm MSK\"/>"
And more pictures available weather schedule for the week and so on. Just take it!
That's all

I'm writing a ruby script whose purpose is generating contracts. It is very simple to implement. I just load up a bunch of variables and input those into a big string all at once like so:
outputstring = <<-eos
#{Time.now.to_date.to_s}
...
eos
It has a bunch of other fancy words after the date, but I want the date to be something like: "January 1st, 2015". I could manually implement all of this noise, but I'm thinking there has got to be a gem that will quickly handle this task for me. I see gems like number_in_words and have to wonder..
Thanks
Does it have to be a gem?
What about this:
2.0.0-p247 :001 > Time.now.strftime("%B %-d, %Y")
=> "August 7, 2014"
and/or
2.0.0-p247 :002 > Time.parse("2015-01-01").to_date.strftime("%B %-d, %Y")
=> "January 1, 2015"
(you might have to require 'time' for the second example

Is there a Sublime Text plugin for Ruby that, after I type class/def something + Enter, will automatically insert end and place the curser in the class/method?
For example, typing def initialize(args) + Enter would result in:
def initialize(args)
#cursor here
end
In Textmate if you type def + Tab, it sets things up for you like that. I believe Sublime does the same.
I haven't used sublime, but here is what i found.
you could create snippets using Ruby on Rails Snippet package
You could use the solution given in 'How to automatically add "end" to code blocks?'.

I am running an automated test script written in Ruby in which I get a result page, I would like to capture some of the text on the page and print them in a file. Can anyone assist with this effort?
Like the comments say, use Nokogiri.
Install it with gem install nokogiri.
To print the first top-level heading from example.com:
require 'nokogiri'
require 'open-uri'
doc = Nokogiri::HTML(open("http://www.example.com/"))
puts doc.css("h1").first
For more information on finding the text you want, try this guide

Does anyone know of a good online API that can translate EAN/GTIN barcodes to the product name (and if possible anything extra such as category?)
I have been unable to find one that has a good success rate, below are some barcodes from items just scanned around my house (nothing rare or obscure)
Example barcodes:
5010186014550
20411336
21048753
5449000000996
5051413363249
try this: http://openean.kaufkauf.net/
here is the API link for it: http://openean.kaufkauf.net/api.php
or this: http://www.codecheck.info/
Both are in german but the language doesn't matter, EAN is EAN :).
try your barcodes there, maybe the database contains your EAN's.
This database seems even larger:
ean-search.org
They also have a REST API.
Here is a comprehensive one from Norway:

I need to find the city and state from a zip code. Does anyone know a good plugin/API that I can use to do this?
gem install geokit
In IRB:
require 'geokit'
geo = GeoKit::Geocoders::MultiGeocoder.multi_geocoder('90210')
if geo.success
geo.state # => CA
geo.city # => Beverly Hills
end
A more lightweight option is the Area gem.
require 'area'
'11211'.to_region #=> "Brooklyn, NY"
See Jason's answer. It works nicely.
The problem is that the USPS doesn't allow bulk downloads of their zip-code lists unless you pay for it. Google's API, which is used in the gem mentioned by Splashlin, no longer seems to support the city and state, instead it now returns the area code:
require 'open-uri'
require 'json'
json = JSON::parse(open('http://maps.google.com/maps/geo?q=852581').read)
puts json
# >> {"name"=>"852581", "Status"=>{"code"=>602, "request"=>"geocode"}}
This page shows some ways you could roll your own. The sources of the data might not be current though:
