Functional languages compiled to JavaScript in practice
Mladý, Lukáš ; Bruckner, Tomáš (advisor) ; Kosek, Jiří (referee)
The thesis focuses on functional principles applied in front-end application development. The main goal is to analyze applicability of functional language Elm in practice, in comparison to contemporary JavaScript that builds on React and Redux libraries. The goal was attained through analysis and comparison of JavaScript and Elm in regards to their architecture and support of real-life front-end application development. Main contribution of this thesis lies in comprehensive analysis and overview of front-end development using JavaScript and Elm. It offers strong argument for using Elm in practice today. It also fills a gap in BroadcastChannel API support in Elm using a dedicated package. The text of this thesis begins with a functional principles support analysis in JavaScript. Next, it describes the most used functional languages compiled to JavaScript, including their applicability by JavaScript developers. Then it compares front-end architecture of both JavaScript and Elm followed by a real-life development experience analysis. The thesis concludes with a practical implementation of a package that fills in for missing BroadcastChannel API support in Elm.

CSS and options of print output
Dařílková, Jana ; Kosek, Jiří (advisor) ; Hradil, Jiří (referee)
The bachelor thesis deals with the possibility of using CSS (Cascading Style Sheets) for printing XML documents. The first part of the thesis describes the basics of XML language, DocBook scheme, the issue of stylistic languages including illustrative explanations of how the languages work, it also includes the presentation of possible ways how CSS can be used for printing. Then it defines features of paged media and focuses on using Cascading Style Sheets for printing paged media with the CSS Paged Media module. Last but not least, the thesis discusses CSS preprocessors and their potential contribution to this work and it devotes a careful focus on the selection of tools for the practical realization of the objective of the thesis. The second part of the thesis deals with the practical use of the CSS Paged Media module for printing and it aims to create an easily editable CSS style sheet for formatting different documents written in DocBook. For meeting these requirements it also uses the CSS preprocessor LESS. The whole practical part is also presented and accomplished on the creation of this bachelor thesis. The third and final part of the thesis identifies the areas where CSS or other used tools struggle with providing sufficient support for creating quality printed output.

Automatization of the digitization workflow of the National Library of Technology
Řihák, Jakub ; Kosek, Jiří (advisor) ; Římanová, Radka (referee)
This diploma thesis is focused on the automatization of digitization workflow in the National Library of Technology, Prague, Czech Republic. This thesis examines possibilities of digitization processes automatization by means of scripts written in Perl programming language and Apache Ant build tool. The advantages and disadvantages of both solutions are analyzed as well as their suitability for automatization of digitization workflow. Based on the comparison of both solutions, the scripts in Perl programming language are selected as the most suitable solution for automatization of digitization workflow. The question whether Ant build tool could be used for the purpose of automatization of digitization workflow is also answered in this thesis. The Ant build tool could be used for the above-mentioned purpose. However, once the activities in the given process divert from the general scope of tasks provided by the Ant build tool, the complexity of the whole solution increases rapidly. This complexity is given by the necessity to use predefined tasks -- sets of functions which have to be combined to create a functional automatization script. Even though Ant is an extendable tool, it is necessary to understand the Java programming language in order to create a new Ant task successfully. On the other hand, the Perl programming language allows easier customization of the script for the purposes of automatization of digitization workflow. Also, the modularity of the Perl programming language makes it easier to create those scripts and modify, correct or develop them even further.
