This request is to convert the DetectLanguage Exception handling class to StandardError. Ruby exception handling in classes (IMUnderstanding) should be based on StandardError and not ::Exception.

Almost all rescue blocks around Gem calls are coded "rescue => e" which defaults to StandardError. Exceptions from DetectLanguage are not rescued in this case and the programmer must then figure out that "rescue DetectLanguage::Exception => e" does indeed catch errors.

RubyGems.org doesn't report a license for your gem. This is because it is not specified in the gemspec of your last release.

via e.g.

  spec.license = 'MIT'
  # or
  spec.licenses = ['MIT', 'GPL-2']

Including a license in your gemspec is an easy way for rubygems.org and other tools to check how your gem is licensed. As you can imagine, scanning your repository for a LICENSE file or parsing the README, and then attempting to identify the license or licenses is much more difficult and more error prone. So, even for projects that already specify a license, including a license in your gemspec is a good practice. See, for example, how rubygems.org uses the gemspec to display the rails gem license.

There is even a License Finder gem to help companies/individuals ensure all gems they use meet their licensing needs. This tool depends on license information being available in the gemspec. This is an important enough issue that even Bundler now generates gems with a default 'MIT' license.

I hope you'll consider specifying a license in your gemspec. If not, please just close the issue with a nice message. In either case, I'll follow up. Thanks for your time!

Appendix:

If you need help choosing a license (sorry, I haven't checked your readme or looked for a license file), GitHub has created a license picker tool. Code without a license specified defaults to 'All rights reserved'-- denying others all rights to use of the code.
Here's a list of the license names I've found and their frequencies

p.s. In case you're wondering how I found you and why I made this issue, it's because I'm collecting stats on gems (I was originally looking for download data) and decided to collect license metadata,too, and make issues for gemspecs not specifying a license as a public service :). See the previous link or my blog post about this project for more information.

I'm pretty sure this famous phrase from H. P. Lovecraft's The Call of Cthulhu is NOT Irish.

irb(main):006:0> DetectLanguage.detect("Ph'nglui mglw'nafh Cthulhu R'lyeh wgah-nagl fhtagn")
=> [{"language"=>"ga", "isReliable"=>true, "confidence"=>5.01}]

Hi! I'm trying to use your service to validate that the input written by the user is in English. Since this particual input is used for users to describe their background and specialty, the term "UI Designer" is very frequently used... But I'm not able to validate it correctly with your service since it defaults to consider it Portuguese. Any chance this could be corrected?

hi,

Please help me, I found this error recently.

info = DetectLanguage.detect(content)

Hi, thank you for your work! :)

My app raised this error sometimes when I use DetectLanguage.detect method.
I think it's the API that return unexpected format like empty array or empty body.
I will make a Pull request with this correction for this particular error, it might fix the error and return nil if the data is not well formated.

I can't see what string I send to the gem, The API seems to return at least {"data":{"detections":[]}} but maybe there is a special case.

def detect(data)
  key = data.is_a?(Array) ? 'q[]' : 'q'
  result = client.post(:detect, key => data)
  result.fetch('data', {}).fetch('detections', nil)
end

let me know if you have another idea or if this seems not good for you :)

(Sorry if my english is not correct)
