This page is all about Google Summer of Code 2010 for Go-OO.

Check the timeline, and propose your own ideas :-)

How to submit your project

This year we are requiring the applying students to do some little exercise. This will help you to get started in the ooo-build code and will help finding out the best of two almost identical project submissions.

Feel free to discuss your submission with the contact person or the community.

The exercise

1. checkout & build ooo-build latest dev milestone
2. run it
3. run it inside gdb (preferably - you're free to use any other debugger on your platform of choice; asking us questions about your choice will get you a few points withdrawn, succeeding on your own gets you a bonus)
4. find the code that handles the keyboard shortcuts, and swap the behaviour of Ctrl-S and Ctrl-N - note that we want a c++ code change, no change in the xml configuration files
5. mail, or attach to your application, the patch for that "fix"

Hints

• Start with the main ooo-build wiki page, it will lead you through
  • Getting the sources
  • Build them
  • Will help you to start hacking
  • Informs you about debugging tricks
  • And will tell you how to contribute

• OpenGrok to search in the sources Some hints already given to students:

• In order to identify the shortcut's code, consider adding some good breakpoints and have a look at the backtrace.

Methodology and advices

What follows, is thought for students applying for Google SoC, but not only ;)

What we need is to use a better methodology, and below, some advices :

Time

• no hurry : the timeline for SoC is well defined, so take the time to do things properly. Sometimes, nothing works. That's life. Just notice everything you did, and retry later
• be sure you completed a task before to start another one
• keep traces : keep every log, even obvious information : later, this might be problematic to retrieve some values
• work regularly : note everything you do, every day

Communication

• english is the common language, but do not forget that a lot of us are not native speakers;
• please do not use private mails, but use the ooo-build list, and only this one for any technical question, and answer GSoC relevant from the students and the mentors point of view ;
• be often online, on IRC #go-oo as mentionned by Fridrich and Cedric
• * when something goes wrong : tell us, *asap. Of course, everyone can do errors, and we won't eat you, because you did not understand something (maybe us too ...), and explain is sane and safe for everybody.
• someone reading your notes, MUST understand what you did. If this is not the case, please improve the document.
• screenshots, blog : use english preferently

Organization

• organize your work as well identified tasks, (include parallel tasks is a good idea): a timeline, Gantt diagram, containing the timeline you proposed is a very good starting point -> on the wiki
• when you start a task, think to avoid redo the same thing twice.
• explain what you do, add references in the code. On the wiki, describe with right sentences, containing one subject, one verb and everything to avoid misunderstanding ;
• my experience told me, that to notice everything important, a tool like a simple text file, with an ACCURATE name (what it does + date), put in an accurate directory for backup, is far enough : simple and robust

Tools

• describe how you did a full build, including details (evil in the details)
• describe all operations you did starting from build with debug enabled until where you put the fat lib, including how :
• before to start debugging : define what you want to do, and what you'd like to observe, how ...
• when you debug :* keep the history*, and the results, what you did. A text file is perfect

Coding

• separate the "what" and the "why" in your analysis
• 80% of the time : think. 20% code (not the opposite)
• do peer reviews as much as often
• be open to suggestions, and do not fear to redo everything
• warnings are errors
• think twice the naming of your class, methods, and verify it does match with the current code
• make it work, simplify, and improve.
• for every method, write an unit test, to check whether the methods does its role, and ony its role
• deliver clean diffs. See the rules on ooo-build wiki to create correct diffs (please add your remarks, and so on ... )

Preparing a good application

In order to have the best application ever produced you should work hard on the following points.

• Complete the exercise. This helps us to check if you are willing to get it working and it helps you to get started with the ooo-build development.
• Expose what you plan to do on the task. Details on the UI, feature, implementation are really important as they help us to see if you have at least studied a bit the feasibility of the task. We will always prefer someone bringing some ideas of implementation even though some might not be 100% exact. You can contact the community if you have some question about the existing code to help you come up with those details: we are always pleased to guide someone through the code ;)
• Propose some temporary schedule for your summer. This helps us to check your progress later and to determine if your schedule sounds possible.
• Explain why should we choose you. Don't forget that their might be several other students working on your topic: we want to choose the best one, then you need to explain why you would be the ideal candidate.

Proposals

Feel free to add your own ideas and proposals; in case there's currently no mentor assigned to an idea, just mail the poor gsoc admins (fstrba at novell dot com or cbosdonnat at novell dot com) and they'll get you one.

Applications (Calc, Impress, Writer)

Attach Impress animations to styles

Currently, Impress styles control most of the visual shape appearance, but not the slideshow animation effect. Which is a pity, as the styles concept is pretty powerful inside OOo, and provides a nice way to change animation settings and type for a great number of objects simultaneously. For a slightly different view onto the same problem, see this bug report.

Impress slide layout extendibility

Make Impress layout templates easily extendible. Currently, the slide layouts in Impress (e.g. "Title page", "Outline page") are a hard-coded set; it would be really cool to have them extendible or even user-editable. This task has been almost completed in the 2009 GSoC term, see 2009 wrapup for the details - there's though still enough work left to make this more useful, e.g. having user-editable layouts.

Implement additional 3D slideshow transitions

Building on top of a successful GSoC project from two years ago, the goal is to add more 3D transitions to the Impress application. A transition is an animation where one page is visible in the beginning and another in the end. It is used during presentation slideshow to switch pages.

The already existing OpenGL transition engine gets the previous and next page as a prerendered image, and then gets the stage (i.e. the screen) exclusively, for the duration of the transition.

Natural sorting in listboxes

A lot of places in OOo list stuff like styles, references etc. sorted like a computer does, i.e. "1, 10, 2, ...". Which is ok though not nice for 5 items, but a PITA for a hundred. This is either some amount of work to find and fix all the places, or a task for a smart cookie to find the silver bullet that fixes this with a central 100 lines patch.

Make autocompletion word lists persistent

People are lazy, and OOo's word autocompletion is a nice feature to save on typing - only that it doesn't offer a way to store your favorite word list persistently.

The task at hand would be to extend OOo's core to load and save those lists, independent of actual documents, in a way similar to what the autocorrection feature offers. This also includes adapting the UI.

Address map SmartTag

We often see addresses in documents and we sometimes want to see where it is on a map. Writer provides a way to extend the contextual menu for the selection: the SmartTags. The goal of this project is to implement an OOo extension providing a Smart``Tag detecting some addresses in Writer documents and allowing the user to see it on a map.

Detecting an address in a chunk of text is a hard task as this depends on the locale of the user and its habits to write addresses. A nice algorithm to detect addresses is more than welcomed, but if not possible any efficient possibility requiring some input from the user is acceptable.

As this task is pretty easy, additional propositions for the project are welcomed: e.g. extending OOEclipse to help creating Smart``Tag extensions, or some other related task.

Translation with memory

This project aims at providing a translation feature in the different OOo applications (not only Writer). Professional translators are usually using a translation memory (TM) tool to avoid translating the same sentences several times. The developed feature will then have to store and query the translations in a TM, either a local one or a remote one. As there are a lot of TM tools (open source and proprietary), the code will have to be extensible by OOo extension to provide the access to the Translation Memory. The core of the feature will be part of the OOo core and a simple connector to a TM will have to be written.

Various TM tools or libraries:

* Benten Eclipse plugins: http://en.sourceforge.jp/projects/benten/

* Java classes to read TMX files: http://www.tecnick.com/public/code/cp_dpage.php?aiocp_dp=article_tmx

Filters

Create a Visio import filter for Draw

OOo currently lacks support for a Visio import filter. This proposal is about writing one, using the ODF format as the transport format to be loaded by the OOo application. Although a full blown filter seems to be unrealistic to be written within the short timeframe, large parts of Visio documents should be able to be filtered correctly.

Improve RTF Import (RTF Tokenizer)

For the ooxml Word import filter, a new filter framework is developed that has better import quality as the old separate filters, and also shares quite some code. Having the RTF import use that framework would be hugely useful; both binary doc and rtf are very similar in structure, and could have tokenizers plugged into the filter framework (and thus being handled by the same high-level filter code). The doc tokenizer is already worked on, so a RTF tokenizer would be a an awesome feature.

Integration/porting

Maxima Integration

Integrate the Maxima symbolic computer algebra system into OOo, to solve calc problems in Writer.

The idea : create a Maxima session inside an OOo Writer document, in an embeded frame, or equivalent.

IMPORTANT :

* Weekly IRC meetings.

* Wiki use mandatory.

* Specifications and documentation MUST be written in parallel, in same time the code is written.

* Every diff of code will be documented on the wiki.

* the code must be written in C++ (prefered).

Iterations

Step 1

1. Discover and learn UNO API

1. be able to create a Writer document (and play with it)

1. be able to launch an external application using UNO

In parallel : learn how a Writer document is structured and how to use it programmaticaly (structure, foundations)

Step 2

1. Learn Maxima session requirements
2. implement a way to launch a Maxima session from OOo
3. implement a way to exchange datas with the open Maxima session
4. propose a follow up for the devs who will continue the implementation Estimated Timeline

* 3 weeks of work = step 1

* 5 weeks of work = step 2 Required skills/knowledge

Patch Open Office to use native GTK for menus and implement a Global Menu client inside it.

It has been long known that OpenOffice doesn't use native GTK, and therefore can not benefit from the Global Menu's GTK Plugin. However no fully usable office suite that utilizes native GTK is available. The result is direct: on a desktop with Global Menu enabled, the default office suite, which is accessed by the user almost everyday becomes an exception that behaves differently from all other applications. Too bad. This proposed SOC project aims to provide a patch for the Open Office & Global Menu users. With the work planned in KDE to implement a GlobalMenu and XFCE already working, this will provide one of the last parts in an integration on the main Linux desktop environments.

Improve Mono integration with OOO-Build

Currently ( see. http://go-oo.org/discover/ ) ooo-build supports some Mono integration, but.. unfortunately currently the integration is more or less 'mono'-directional ( if you pardon the pun ) The existing integration only allows a mono client to 'drive' OpenOffice. To exploit 'mono' more effectively it would be cool to allow 'mono' functionality to be called from OpenOffice to do that we need to be embed mono in OpenOffice. There would be 2 ways then to allow OpenOffice to 'trigger' mono code

1. via the scripting framework which would allow mono code to be called for various 'events' triggered by user actions ( clicking a button, or selecting an item on a custom menu ) or from application/document ( open, close etc. )
2. enabling mono code to define an uno service, in other words allow an uno service written in mono to be registered with OpenOffice ( just like services written in c++ and java ), a new loader would need to be written that would allow the mono service to be instantiated. Although (1) above could be considered a task in it's own right (2) is a far more powerful and interesting prospect as it allows the mono code ( defined as an uno service ) to be run by any OpenOffice/uno aware code ( e.g. basic, c++, java, python ). To use those uno mono services from events as described above it would be just a simple matter of using some Open``Office basic glue code ( about 3 lines ). Creating some scripting framework services (1) could be done if time permits to allow direct binding of mono functionality to the various classes of events that support the scripting framework, those scripting framework services of course could be written in mono themselves

What needs to be done ? As a mono bridge already exists a new loader (see http://api.openoffice.org/docs/common/ref/com/sun/star/loader/XImplementationLoader.html) would need to be implemented. Some static symbols in the mono implementing assembly would probably need to be agreed in order to facilitate discovery and instantiation of the mono service(s) Additionally we could even think about tweaking the package management so that extensions written in mono could be supported.

IDE integration for new container controls

Currently in ooo-build ( and on the way upstream via cws container_controls ) we have introduced some new controls

• Frame
• TabControl (MultiPage) These controls are currently only useable via the api, its not possible to use the Dialog designer to interact with them. The task would be to modify the IDE Dialog designer to allow a user to interact with those controls.

Note: The existing dialog designer code doesn't at all support the concept of a control being 'inserted' into an existing control. Additionally when that control is something like a Tab/Multipage control things get more complicated as it needs to be possible to select the actual page of the multipage ( that is in design mode ) to insert a new control into. Also it must be possible to add/delete pages to/from the Tab/Multipage control.
