Reading/Web/PDF Functionality/fr

Update September 2017
Our current PDF rendering service, the offline content generator (OCG), is no longer maintainable. Simply put, it's breaking down. The Reading team at the Wikimedia Foundation has been working towards replacing it for months. Originally created by a third party, OCG has been running on outdated code which may introduce security vulnerabilities and other major issues in the future. Over the last three months, we’ve had banners on the PDF creation page asking for feedback on the prototype for our new renderer. The new renderer will have improved capabilities from OCG – it will be able to print tables and infoboxes and will contain styling focused on better readability. We've gathered a lot of good feedback on the prototype and are working on making the required updates to our new PDFs.

Unfortunately, major issues with our old renderer (OCG) will require us to remove it as a rendering option prior to completing the necessary updates for the books feature. This is earlier than we wanted. By the time we remove OCG, the work for rendering of single articles will be completed. However, the rendering of books will be missing certain functionality, in particular styling and table of contents. We will be working to build out this functionality over the following months and hope to release the full experience in November–December, 2017.

Timeline:
 * Release of full-featured renderer for single articles (print to pdf) – Oct 1, 2017
 * Release of OCG replacement for books – Oct 1, 2017
 * Sunsetting of OCG renderer – Oct 1, 2017
 * Release of full-featured books renderer – Nov–Dec, 2017

Functionality:

For a full list of current and upcoming functionality, see below.

In addition to this page being updated, this will be communicated in a banner on PDF creation page, in Tech News and on some Wikimedia mailing lists.

Introduction
Our current PDF rendering service, the offline content generator, is no-longer maintainable. Simply put, it's breaking down. Originally created by a third party, it currently runs on outdated code which may introduce security vulnerabilities and other major issues in the future. If we're to have the PDF functionality, we unfortunately have to replace it, or we might suddenly find ourselves in a situation where we'd have to take it down without having planned to do so.

Additionally, it does not support a number of rendering requests from the community, the main one being the ability to render tables. We have selected a new service, the electron rendering service, as a suitable replacement. Our next step is to duplicate the functionality provided by OCG using the electron rendering service. Below, we will describe the main portions of the functionality we have identified as necessary. We would like to invite conversation around what is missing or what is superfluous in the provided list. We would also like to highlight over our future plans for PDF rendering to gather initial feedback.

Historique

 * Le rendu des articles en PDF et des livres provenant des pages de Wikipedia est géré par un service appelé OCG. Lorsque vous créez des "livres" à travers le créateur de livre, il utilise OCG intégré dans l'extension Collection. OCG a plusieurs problèmes, en particulier avec des tableaux.
 * Multiple issues with OCG are identified, including complaints from the community around OCG's inability to render tables.
 * Rendering of tables ranks as number 9 on the German-speaking Community Technical Wishlist.
 * Wikimedia Deutschland begins on working on a solution for rendering tables in PDF's, and introduces Electron. They do this planning to run it alongside OCG, not to replace it.
 * At the same time as Wikimedia Deutschland is working on the Electron service, the responsible maintainers of the OCG service at the Wikimedia Foundation come to the conclusion that OCG has to be replaced.
 * The WMF Reading Team takes over the responsibility for the long term maintenance of PDF rendering begins plans on implementing table rendering across all projects.
 * The Reading team launches a community consultation for gathering feedback on Electron.
 * The Reading Infrastructure and Web teams begin scoping the working necessary to port OCG functionality over to the Electron service.

Update After Consultation
We launched a consultation on the current implementation of the PDF renderer in early June, 2017. After reviewing the consultation responses, we have made the following observations:
 * A larger number of users preferred the single-column format over the double column format
 * Users which prefered the double-column format highlighted that their preference was based in the styling and look and feel of double columns. Some users also expressed concerns with font size and wasting paper when printing PDF's in the single-column option
 * The following feature requests were made:
 * Functional hyperlinks
 * Date and url, 'this page downloaded [date] from [URL]'
 * Customizable css for layout, title, TOC
 * Option for 2 column format
 * Include/exclude images versions
 * Modifiable margins
 * print by section - allows you to remove references, paragraphs you don’t want, index, etc
 * allowing configurable text size

Based on the feedback, we have incorporated the following into our new print styles:
 * hyperlinks
 * article information
 * smaller font and book-like styling

The remainder of the requests above will be postponed until the second iteration of the PDF renderer, in which we plan to build a settings mode that will allow for customization of the available options.

Proposition
Voici une proposition pour la portée des fonctionnalités nécessaires au rendu PDF :
 * Individual articles will be rendered to PDF using the "Download as PDF" link in the sidebar
 * Multiple articles will be rendered to PDF using the Book Creator tool
 * All articles will contain attribution for text and images
 * All PDF's rendered will be able to print tables
 * Users will be able to customize the layout of their PDF (optional)

Design
The new PDF styles will be designed for increased readability. Based on community feedback and qualitative or quantitative testing, support for a 2-column layout may be built for the book creator and/or for individual PDFs.
