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


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, active community•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 REST is the existence of resources (sources of

specific information), each of which is referenced with a global identifier (e.g., a URI in HTTP). In order to manipulate these resources, components of the network (user agents and origin servers) communicate via a standardized interface (e.g., HTTP) and exchange representations of these resources (the actual documents conveying the information).


Web Architectures - REST• http://en.wikipedia.org/wiki/Representational_State_Transfer• http://prescod.net/rest/mistakes/


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


•OpenID – a standard that describes how users can authenticated in a decentralized manner


•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


Why Not an IDE in a Browser?


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)


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


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 with SCMs: Git is used to speed up self-hosting There is ongoing effort on enabling RTC in 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


Integration Possibilities (Demo)

•Create project initializr.com

•Import zip•Disable jslint•Go to page

(comment in log)


Getting Started• Homepage / OrionHub: http://eclipse.org/orion•Installing on localhosthttp://wiki.eclipse.org/Orion/How_Tos/Install_Orion_on_Localhost

• Clonning git://git.eclipse.org/gitroot/e4/org.eclipse.orion.client.git git://git.eclipse.org/gitroot/e4/org.eclipse.orion.server.git https://github.com/eclipse
