Mobile Site Rewrite
Mobile Site Rewrite Patrick Reilly — Senior Developer Mobile Wikimedia Foundation Current implementation ● Ruby based mobile gateway utilizing Merb Process: ● A request comes in from a mobile browser ● The request generates a Device object in merb/extensions/request_extension.rb ● The Device object picks a format in Device#format_name ● Any method_missing that Device receives is looked up in the format specification ● The formats are specified in config/formats.yml ● An Article is fetched for that device ● First, the article figures out what kind of parser needed to be run on the page It then generates a key with that parser type. ● It then checks to see if that has been cached ● If it is not cached, it grabs scrapes the Wikipedia page and processes it with some /app/models/parsers/* class ● If it is cached, it returns that cached object ● The layout is generated with the returned Article#html ● The device format is used heavily here (aka, "= current_device.stylesheet_name") ● An "app/views/layouts/search#{format}.html.haml" file is rendered in the search area ● Changes in the search box and CSS fields are the biggest difference between formats Mobile site rewritten in PHP ● Having the site in Ruby causes a number of headaches (for code review, code deployment, and server maintenance) given Wikimedia's mostly PHP-based infrastructure. Rewrite rationale ● Puts the code in our code repo rather than on github ● Easier to review code in a language that most Wikimedia/MediaWiki developers are already using (PHP, instead of Ruby) ● Easier on -

TOMÁŠ VOJNAR, Ph.D. VEDOUCÍ PRÁCE BRNO 2016 Abstract The aim of this thesis is to research the differences between the CSS preprocessor languages, namely Less and Sass, and find applicable transformation methods to implement a converter between their dynamic stylesheet formats. A general introduction to the concept of CSS preprocessors is provided first, which is followed by a thorough description of the Lessand Sass language features. In addition to this, all the discovered differences are stated and illustrative examples of the invented conversion methods are provided in this work. This is followed by the description of the design and implementation of the proposed converter. As a part of the contribution of this thesis, a CSS comparison tool based on abstract syntax tree transformation has also been developed. Its design is described along the testing procedure used to verify the invented conversion methods. The last part of the work summerizes the achieved results and the future directions of the converter. Abstrakt Cílem této bakalářské práce je výzkum rozdílů mezi CSS preprocesorovými jazyky, jmen- ovitě Less a Sass, a nalezení použitelných transormačních metod k implementaci překladače mezi jejich formáty. Nejprve je předložen koncept CSS preprocesorů a následuje detailní popis vlastností jazyků Less a Sass. V této práci jsou uvedené všechny zjištěné rozdíly, a pak jsou představeny nové konverzní metody s demonstrativními příklady. -
