Jiří Vraný, Ph.D. V Liberci 15. 5. 2013 Prohlášení Byl(a) jsem seznámen(a) s tím, že na mou bakalářskou práci se plně vztahuje zákon č. 121/2000 Sb., o právu autorském, zejména § 60 – školní dílo. Beru na vědomí, že Technická univerzita v Liberci (TUL) nezasahuje do mých autorských práv užitím mé bakalářské práce pro vnitřní potřebu TUL. Užiji-li bakalářskou práci nebo poskytnu-li licenci k jejímu využití, jsem si vědom povinnosti informovat o této skutečnosti TUL; v tomto případě má TUL právo ode mne požadovat úhradu nákladů, které vynaložila na vytvoření díla, až do jejich skutečné výše. Bakalářskou práci jsem vypracoval(a) samostatně s použitím uvedené literatury a na základě konzultací s vedoucím bakalářské práce a konzultantem. Datum Podpis 3 Abstrakt Česká verze: Tato bakalářská práce se zabývá srovnávacím testem webových aplikací psaných v programovacím skriptovacím jazyce PHP, které využívají různé knihovny pro komunikaci s databází. Hlavní důraz při hodnocení výsledků byl kladen na rychlost odezvy při zasílání jednotlivých požadavků. V rámci řešení byly zjišťovány dostupné metodiky určené na porovnávání těchto projektů. Byl také proveden průzkum zjišťující, které frameworky jsou nejvíce používané. Klíčová slova: Testování, PHP, webové aplikace, framework, knihovny English version: This bachelor’s thesis is focused on benchmarking of the PHP frameworks and their database libraries used for creating web applications. -

What Is Dart?
1 Dart in Action By Chris Buckett As a language on its own, Dart might be just another language, but when you take into account the whole Dart ecosystem, Dart represents an exciting prospect in the world of web development. In this green paper based on Dart in Action, author Chris Buckett explains how Dart, with its ability to either run natively or be converted to JavaScript and coupled with HTML5 is an ideal solution for building web applications that do not need external plugins to provide all the features. You may also be interested in… What is Dart? The quick answer to the question of what Dart is that it is an open-source structured programming language for creating complex browser based web applications. You can run applications created in Dart by either using a browser that directly supports Dart code, or by converting your Dart code to JavaScript (which happens seamlessly). It is class based, optionally typed, and single threaded (but supports multiple threads through a mechanism called isolates) and has a familiar syntax. In addition to running in browsers, you can also run Dart code on the server, hosted in the Dart virtual machine. The language itself is very similar to Java, C#, and JavaScript. One of the primary goals of the Dart developers is that the language seems familiar. This is a tiny dart script: main() { #A var d = “Dart”; #B String w = “World”; #C print(“Hello ${d} ${w}”); #D } #A Single entry point function main() executes when the script is fully loaded #B Optional typing (no type specified) #C Static typing (String type specified) #D Outputs “Hello Dart World” to the browser console or stdout This script can be embedded within <script type=“application/dart”> tags and run in the Dartium experimental browser, converted to JavaScript using the Frog tool and run in all modern browsers, or saved to a .dart file and run directly on the server using the dart virtual machine executable. -

In order to implement a Java macro you will need to write 2 classes: • One that representing the allowed parameters, including mandatory parameters, default values, parameter descriptions. An instance of this class will be automatically populated when the user calls the macro in wiki syntax. • Another one that is the macro itself and implements the Macro interface. The XWiki Rendering Architecture can be summarized by the image below: The Parser parses a text input like "xwiki/2.0" syntax or HTML and generates an XDOM object. This object is an Abstract Syntax Tree which represents the input into structured blocks. The Renderer takes an XDOM as input and generates an output like "xwiki/2.0" syntax, XHTML or PDF. The Transformation takes an XDOM as input and generates a modified one. -

Typically, these applications are built using heterogeneous technologies and consist of code that runs on the client (e.g., Javascript) and code that runs on the server (e.g., Java servlets). Even simple web applications today may accept and process hundreds of different HTTP parameters to be able to provide users with rich, inter- active services.
