Built using the open web standards you know and love, Opera Dragonfly’s source is available to view. Not only that, but it is released on a open source BSD license, meaning it is free as in freedom as well as in beer.
Opera is normally one of the few browsers that isn’t open source, but they are certainly doing more with open source itself. David Storey has announced how Opera Dragonfly has joined the open source ranks.
There is Dragonfly itself, but also the Scope protocol:
Starting today, Opera Dragonfly is a fully open source project, hosted on BitBucket. Since the previous version of Opera Dragonfly, a lot of work has gone on behind the scenes replacing the existing architecture with a modern version of the Scope Protocol – STP-1. Opera Dragonfly has been rewritten to use this faster and more efficient version of Scope. Now that we believe that the underlying protocol is stable and performant, and a public desktop build has been released with this included, it is time to put Opera Dragonfly on a public Mercurial repository.
If you have a Mercurial client you can visit the Opera Dragonfly STP-1 repository and check out the source code. We have provided initial documentation in the Wiki to get you started. This is Opera’s first full open source project, so there will be a learning curve. We ask you to bear with us while we get everything up and running and policies in place. Coming from a closed source background there are some hurdles to overcome, such as the current bug tracking system being on a closed server. We hope to migrate to an open bug tracking system as the project gets on its feet.
As well as the current and previous versions of the Opera Dragonfly source code, we have released a couple of tools to help with Opera Dragonfly development. The first is Dragonkeeper. This is a standalone proxy, which translates STP (Scope Transport Protocol) to HTTP. This can also be useful for remote debugging. The second tool is Hob. Hob is a utility to create code from Protocol Buffer descriptions. Protocol Buffers are one of the formats Scope STP-1 supports along with JSON and XML.
Nice. The question is…. will others implement on STP so we can get cross browser support.
