=Description=
This project aims to turn the [http://142.204.133.123/dxr DXR] into an extension that can be installed in Firefox or distributed as a XUL/[http://labs.mozilla.com/2007/10/prism/ Prism] application. This will allow developers with limited or no internet connection to access it the Mozilla source code and documentation in an offlineenvironment. The extension will also provide a low-bandwidth solution for pushing applying updates on a timed interval or at the user's command. The [http://142.204.133.123/dxr DXR] is a compilation of Mozilla developer documentation. The plan is for this material to be distributed on a Fedora Live DVD that will allow the user to access these materials offline or, alternatively, install them for use on a Windows machine. Currently the endLocal MXR and MDRK exist as web applications that run only on Fedora and require the installation of MySQL, Perl and apache. These projects have to be setup manually and are not installable.Our part in this project would be to convert these projects so that they can be installed cross-userplatform as a Mozilla Firefox extension.

* [[Mozilla_Developer_Resource_Kit|Mozilla Developer Resource Kit]]: This is the over-arching project of which the PDXR is but one piece.
* [[Creating_an_MDRK_spin|Creating an MDRK spin]]: This is how this project will eventually be distributed.
* [[Create_Local_MXR|Create a local mxr]]: It is hoped that by solving the more difficult problem of packaging the dxr, the problem of packaging other materials such as an mxr or developer documentation will also be solved.
==Technical Overview==
===Business Rules===
* Commit to lowest file size bandwidth
===About The SourceCode===
* Backend: Perl
* Database: SQLite
* Interface: XUL
===Perl Interpreter===
Perl will be needed to create pages from database queries. It needs to be able to run from within the extension on Windows, Linux, and Mac. [http://perldoc.perl.org/perlembed.html Perlembed] allows us to use Perl from C, which means that we could compile our program with headers that will be able to alternate between Windows, Linux, and Mac.
===Web Server===

====Application====
======Web Browser======
The application front-end holder. It provides a way for the application to be accessed.
It is not limited to Firefox web browser only, it can also be run as a Prism application.
======Extention======The front-end Portable DXR (our browsable source code documentation) is an applicationthat lives inside our extension. It's The CGI tools exist as part of an embeddable web server. When you remove the DXR part, what you are responsible for communicating left with is the platform on which it runs. It's also worth pointing out that the core application SQLite support is available in two ways. Local storage capabilities using SQLite are build into Mozilla applications and fetching can be accessed by an extension using C++, JavaScript, Python. However, SQLite database files can be accessed by any software that understands the data to format, so SQLite support will also be available through the applicationcgi tools. The DXR application then parses will probably use the CGI tools to access SQLite files if our presentation layer is traditional XHTML. But if we decide to use XUL, we can use the browser's built in functionality directly from JavaScript. In either case, I suspect we will end up leveraging the data and populates built in sqlite support for the UI as neccessaryupdates. But we need to do some research on that.
======DXR======The core application has presentation. The front-end is mostly implemented by [http://vocamus.net/dave/ David Humphrey] on his [http://zenit.senecac.on.ca/wiki/dxr/ DXR]. We need to modify the UI to implement the following functionalities:* Navigation
* Database querying
* Update services
* Data transaction
