Trevor Parscal and Neil Kandalgaonkar have done exploratory work on the visual editor project. Neil worked with developers of HackPad (a custom version of Etherpad, a real-time collaborative editing software) on a proof of concept of integration between Etherpad and MediaWiki (read more). They're now working on turning it into a MediaWiki extension. Work on the visual editor is also intersecting with the groundwork done on the new parser.

Trevor Parscal and Neil Kandalgaonkar have done exploratory work on the visual editor project. Neil worked with developers of HackPad (a custom version of real-time collaborative editing software Etherpad) on a proof of concept to integrate Etherpad and MediaWiki (read more). They're now working on turning it into a MediaWiki extension. Trevor continues to work on WikiDom, a storage structure and functionality acting as an intermediate layer between the parser and a visual editor. This work also intersects with the groundwork done on the new parser.

Trevor Parscal continued to work on the front-end of the visual editor, and specifications for accessing the editing surface via the API. A hybrid rendering approach appears to be the best strategy for the visual editor. Neil Kandalgaonkar continued to work on the middleware, DOM and transactions. Neil also continued to work on a demo to integrate MediaWiki and Etherpad. With Alolita Sharma, they planned their upcoming sprints. Neil and Trevor are posting about their work to the wikitext-l list.

Trevor Parscal continued to work on the front-end of the visual editor and rich text rendering; he was joined by Inez Korczynski, a developer from Wikia, who are also interested in the visual editor. Neil Kandalgaonkar worked on real-time collaboration, concurrent editing and dived into the inner workings of Etherpad. (Read summary on wikitext-l.)

Trevor Parscal and Inez Korczynski worked on a transaction-based model for the visual editor, where the document is built as a series of events (instead of saving it entirely at every change), which makes it easier to undo actions. Neil Kandalgaonkar continued to work on real-time collaboration and is close to presenting a demo of Etherpad working inside a MediaWiki edit window. Ian Baker investigated and started to work on a chat system to be integrated to the concurrent editing interface, for collaboration and live help. More details on the wikitext-l mailing list.

Trevor Parscal expanded the software design documentation. He also refactored some of the data structures to follow a model/view controller pattern and support document-level transactions. He wrote tests for the new structure, and got it to render paragraphs and lists; he's now working on rendering tables.

Trevor Parscal worked on a new model tree (and the conversion from the linear model) and updated the software design documentation. Inez Korczynski worked on front-end functionality: dialogs, selecting text, mouse actions, scrolling, keyboard shortcuts, etc. Roan Kattouw focused on algorithms that insert ranges of data into a document, and Neil Kandalgaonkar on the removal of data. On the parser side, a basic parser using PEG is in place, which produces an intermediate JSON object tree; Brion Vibber is still working on markup support (mixed HTML and Wikitext). Gabriel Wicke joined the team and started to work on the PEG parser (read more).

Trevor Parscal fixed issues blocking the synchronization of structural edits to the user interface, refactored and cleaned up the code, and mapped out tasks and features to be supported. He also finished the document transaction functionality and made progress on an undo/redo system. Roan Kattouw added tests, rewrote some code to make the tests pass, and fixed a number of bugs and issues, notably in Internet Explorer. Inez Korczynski continued to work on content insertion, deletion and selection and fixed numerous bugs. Gabriel Wicke extended the PEG parser for robust larger-scale parsing. He converted the PEG parser into a combined wiki and HTML tokenizer that feeds to a HTML5 DOM tree builder. He implemented several wikitext features (lists, italics, bold) as token stream transformations. 139 of about 660 parser tests are now passing.

<section begin=2011-12-13/>The first public developer prototype of the visual editor sandbox was deployed to MediaWiki.org for public feedback and testing. It can be accessed via the visual editor sandbox special page. Full announcement in the Wikimedia blog.<section end=2011-12-13/>

2011-12-31
<section begin=2011-12-31/>The team deployed a developer prototype of the visual editor sandbox to mediawiki.org for public feedback and testing. Trevor Parscal fixed bugs and refactored code. Inez Korczynski worked on the toolbar (text styles), the undo/redo stack, and lists (creating, deleting, and changing indentation). Gabriel Wicke worked on the parser test runner and the parser pipeline, including [//lists.wikimedia.org/pipermail/wikitext-l/2011-December/000494.html the tokenizer and its grammar] and template expansions. Neil Kandalgaonkar worked on the undo/redo feature and did a lot of refactoring.<section end=2011-12-31/>

2012-01-31
<section begin=2012-01-31/>January was a bit slower on the visual editor front, as parts of the team took some well-deserved vacation after the successful prototype launch in December. During the SF Hackathon, a lot of issues were fleshed out. Plans for the second phase of the editor project were formulated. Inez Korczynski investigated a possible use of  to help with input methods and text selections on mobile devices. Gabriel Wicke extended the parser with the ability to fetch and expand templates in a parallel and asynchronous fashion. The parser now supports most parts of the English Wikipedia Main Page.<section end=2012-01-31/>

2012-02-29
<section begin=2012-02-29/>Trevor Parscal did research on cursor interaction and selection rendering for RTL (right-to-left) and support for line breaks in PRE elements. Gabriel Wicke improved template expansion and parser function support, investigated Microdata and RDFa for WikiText-in-HTML-DOM embedding and added rough support for images and other files. Rob Moen committed a working Editable Surface IME prototype (bidirectional text not fully supported). Audrey Tang joined the team and worked on the sanitizer and the testing process.<section end=2012-02-29/>

2012-03-05
<section begin=2012-03-05/> Exploration of using ContentEditiable (CE) in place of EditSurface (ES) for the display layer was successful, and the team is integrating the new display layer system into the rest of the codebase. Inez and Christian are continuing their work on CE while Rob is focusing on getting the UserInterface (UI) module working with CE. Rob will be refactoring UI and adding an API layer for toolbar and inspector extensions. Trevor and Roan are focusing on DataModel (DM) changes that need to be done to improve tree sync and integration with the parser (Parsoid). Gabriel and Audrey are continuing their work on Parsoid.<section end=2012-03-05/>

2012-03-06
<section begin=2012-03-06/>Last week made big decisions. The big one was to move forward with contentEditable (CE) that Inez and Christian are doing in place of Editable Surface (ES). Looks like editing on mobile will be awesome! Trevor and Roan will be focusing on the data model (DM. DOM -> Linear Parser) as the basic objectives have been hashed out, the (parser -> DM is unaffected). Certain structure changes (i.e. turning paragraphs to lists) aren't currently possible so the DM will change to support that. Linking with the parser (DOM-> LM converter) will be deferred for a week.

In terms of the UI, Rob worked on some RTL in ES, but switched given the CE advances. This week will focus on getting the UI working in CE (assess what UI we have from ES and where it needs to be). Plan on getting to the point we can user test the JS API for the toolbar.

In terms of the parser, Gabriel has to decide on RDFa vs. microdata eventually (difference are minimal, most of the DOM stuff won't change and can be tested with vanilla HTML anyway). Created a dump grepper with syntax highlighting and used that to analyze existing wikilink/image syntax use. Refactored tokenization and expansion of wikilink/images so now image options can come from templates (257 tests passing now). Plan on tackling interacting with action=parse and wiki in general. Also some more parser function tweaking, etc. and the RDFa/microdata decision.<section end=2012-03-06/>

2012-03-20
<section begin=2012-03-20/>Team updated (sans key people who are out of commission): FY2012-2013 goals section. Further updates/corrections by Trevor and Gabriel expected when they return.<section end=2012-03-20/>

2012-03-31
<section begin=2012-03-31/>A big decision in March was to move forward with contentEditable (CE), implemented by Wikia developers Inez Korczynski and Christian Williams, instead of Editable Surface (ES). Trevor Parscal and Roan Kattouw focused on the data model. Rob Moen worked on the user interface, first on right-to-left support in ES, then on getting the UI working in CE. Gabriel Wicke and Audrey Tang continued their work on Parsoid and need to decide on RDFa vs. microdata. They created a dump grepper with syntax highlighting, and used it to analyze existing wikilink/image syntax use.<section end=2012-03-31/>

2012-04-monthly
<section begin=2012-04-monthly/>Roan Kattouw and Trevor Parscal are rewriting the underlying data model (ve.dm) to achieve feature compatibility with the parser and correct a variety of problems that have been previously deferred. Inez Korczynski and Christian Williams have been continuing their work to stabilize and integrate the content editable layer (ve.ce) and have been working with Rob Moen, who has focused on getting the user interface elements working with the content editable layer (ve.ui). Gabriel Wicke has been working on improving the parser's ability to parse pages more quickly as well as increasing compatibility with existing features such as thumbnails. A big template-heavy page like Barack Obama can now be expanded in similar time as the production parser (80 seconds on a puny laptop) and 340MB of memory. It previously ran out of memory after consuming 1.6G and running for ~30 minutes.<section end=2012-04-monthly/>
