RubyLearning caught up with Andrey “A.I.” Sitnik developer of R18n, a tool to internationalize and localize your Merb/Sinatra/desktop Ruby application, and asked him some quick questions in this interview.
Satish Talim>> Andrey, could you tell us something about yourself – your background, where you are based?
Andrey>> I live in Saint Petersburg, Russia and study in Saint Petersburg State Polytechnical University.
I believe in the ubiquity of genetic algorithms and that diversity (of culture, languages, etc) is necessary for progress.
Satish>> What is “R18n” ?
Andrey>> This is the only normal name that isnâ€™t taken by any other Rails plugins
Satish>> What was the idea behind “R18n” ?
Andrey>> I18n logic is the same for any application and doesnâ€™t depend on a framework. So, I think, that i18n library must be agnostic with core gem and gems for “out of box” work with additional frameworks.
Satish>> How does your tool help to internationalize and localize a Merb / Sinatra app?
Andrey>> R18n helps to translate interface and print dates and numbers in user traditions (for example, “27.04.2009” in Russian and “04/27/2009″ in USA). To translate your data (e.g. in database) you need to write you own logic, because itâ€™s very business specific.
Satish>> For a Ruby beginner, can you illustrate the usage of your tool with an example ?
Andrey>> Add R18n to your Sinatra application:\
Now your app has i18n support and you need to add translations file in
i18n/ dir. For example ./i18n/en.yml:\
post:<br /> friends: Post only for friends<br /> tags: Post tags: %1
comments: !!pl<br /> 0: No comments<br /> 1: One comment<br /> n: %1 comments
And use these translated messages in a view:\
i18n.post.friends<br /> i18n.post.tags(@post.tags.join(', '))<br /> i18n.comments(@post.comments.size)
Also it would be good if a user reads numbers and dates in his culture
i18n.l @post.created_at, :date<br /> i18n.l 10000
Satish>> Are you working on any other Ruby based project?
Andrey>> I am working on my science project related to machine learning via genetics algorithms using Ruby and plan to start a genetic algorithms Ruby library.
Satish>> What will be there in the next version of “R18n” ?
Andrey>> I plan a performance optimization (compile translation files?) and a Rails plugin with compatibility with Rails I18n API.
Thank you Andrey. In case you have any queries and/or questions, kindly post your questions here (as comments to this blog post) and Andrey would be glad to answer.
