Conditionally require gems in Gemfile based on Rails or Sinatra framework? -


I am writing a gem which can be used with both sinatra and rail, however, gem dependency is different The framework on which the developer is using the gem.

If this is a rail app, then we need 'saas-rail' and 'coffee-rail'. If it is a seam app, then we need 'asus' and' coffee-scripts. '

Ideally the bundler will install only the necessary gems on which this gem is being loaded, but I do not seem to understand how to specify conditional reliance.

Suggestions will be highly appreciated.

I would suggest you not do this. This hack will be unbelievable.

What you can do though is division and win! Make a generic version of your gem, which is an agnostic and handles only logic, let's call it yourgem-core , you can make two other gems on the basis of that first, Which is yourgem-rail and yourgems-sinatra .

It is much better, only logic and logic test in yourgem-core , only rail integration testing yourgem-rails , yourgem-sinatra Only Sinatra integration test in

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...
