Orion is a web-based IDE being developed by IBM to allow developers to work on code directly within a browser. It uses modern web technologies like REST, JSON, and OAuth to provide features like editing, navigating files, source control integration, and searching across large projects without installing any desktop software. The presentation demonstrated Orion's code editor, navigator, source control status and compare tools, and discussed how its modular design allows integration with other web services and tools.

Agenda
•What is Orion?
•A glance at web technologies
•More about Orion
•Demo
•Discussion and Q&A

3. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved.
Goals of Orion
•Build developer tooling that works in a browser ,
•at web scale,
•integrating well with existing tools that exist on the web,
•based on well ‐ proven web architectures - REST, HTTP,
JSON, OAuth, OpenID, and others.

Use Strengths of the Web
• zero install on the client
• simple connectivity – links
• trivial update mechanism
• powerful rendering engine
• look and feel easy to adapt
• large, activecommunity
• innovation by everyone
• no central “IDE”
• artifacts all over the web
• highly distributed content
• refresh the page
• scalable computing power

Why work on this now?
•There are other online IDEs already, extremely high rate of
innovation in online tools for web development
•We need to start now, learn, fail, try again, in order to
become a player in this space
•We (IBM) would like to see a community to form around
this forms at Eclipse, and are contributing a seed

A Glance at Web Architectures - REST
• An important concept in RESTis the existence of resources (sources of specific
information),each ofwhich is referenced with a global identifier (e.g., a URI in HTTP). In
order to manipulate these resources, componentsofthe network (user agentsand origin
servers) communicate via a standardized interface (e.g., HTTP) and exchange
representationsofthese resources (the actual documentsconveying the information).

A Glance at Web Architectures
•HTTP - a networking protocol for distributed,
collaborative, hypermedia information systems. HTTP is
the foundation of data communication for the WWW
•Ajax - a group of interrelated web developmentt methods
used on the client-side to create interactive web
applications. With Ajax, web applications can retrieve data
from the server asynchronously in the background

A Glance at Web Architectures
•JSON - a lightweight text-based open standard designed
for human-readable data interchange
• JSON vs XML picture

10. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved.
•OpenID – a standard that describes how users can
authenticated in a decentralized manner

11. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved.
•OAuth – an open standard for authorization, which allows
users to share their private resources stored on one site
with another site without having to hand out their
credentials

Orion Assumptions
•Software development in a browser
 editing
 navigating folders
 searching
 working with SCM
•Set of linked web pages, NOT an IDE running in a browser
 easy to integrate other functionality even if hosted on different
servers

Context: Already in a Browser
•Bug tracking (Bugzilla, JIRA, Trac, Lighthouse, Rational
RTC)
•Builds (Hudson/Jenkins)
•Code review (Bugzilla, Gerrit, GitHub)
•Documentation, code snippets (pastebin, Gist)
•Browsing code repositories (GitHub, ViewCVS, Rational
RTC)
•Debugger (Firebug, WebKit Inspector, Developer Tools)

18. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved.
What’s Missing? Not Much
•Code editor
•Navigator
•Work with SCM(commit, compare, merge, etc)
•Indexing - full text search
•Unit tests
•Initial focus on web developers working on client-side
JavaScript, HTML,CSS

19. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved.
Orion Design Principles
•Regular hyperlinks, back button, bookmarking,link sharing
•Functionality on separate pages.
Page = Task + Resource
•Performant and Lightweight. Speed trumps power.
•Components should have value on their own.
•Low barrier of entry for adopters. Don’t require technology
buy‐in.

Demo
• Log in/log out
• openId
• Navigator + editor
• Git status & log
• Compare
• Sites
• Firebug integration
• Search

Integration Possibilities
•Client-side “plug-ins” : adding commands to existing UI
 Integrate withSCMs:
 Git is used to speed up self-hosting
 There is ongoing effort on enabling RTCin Orion
 W3C validator, JSLint, ...
•Hyperlink integration
 Bugzilla, Gerrit, SCM stats
•Integrate with browser debuggers:
 Firebug, WebKit Inspector
•Host additional UI components, e.g. OpenSocial Gadgets
•Server-side
 OSLC: Consume and produce server APIs

Integration Possibilities (cntd.)
•Web-Based integration
 initializr.com - equivalent of “New Project” wizard
 smush.it - lossless “compression” of images
 CSS Sprite Generator
 jsbeautifier.org - JavaScript code formatter

23. Orion - Introduction | Copyright © IBM Corp., 2011. All rights reserved.
Integration Possibilities (Demo)
• Create project
initializr.com
• Import zip
• Disable jslint
• Go to page
