Ruby Licensing

Hi ,
I have some questions regarding the licensing of Ruby & Ruby On
Rails . How does the licensing work in the following situations

A) I write a website using Ruby and Rails where i want to charge
customers for the service
B) I want to sell software written using Ruby and Rails to a client
C) I want to modify core Ruby code and/or extensions from what i
downloaded

In the above cases do i need to give away the software i wrote for
free (or) am i obligated to publish the
software i wrote also as open source (or) do i need to pay at any
stage ?

Thanks for your help!

Hi Peter, please be aware that changes to Ruby Core may cause issues within current and future releases of Rails. Thus, you’ll be reponsible for any changes that you make within both Rails and Ruby that have not been integrated back into their respective cores.

Good luck,

Investigate Rails plugins for modifying Rails or Ruby core. It’s easy, portable, and non-destructive.
