Možnosti generování a využití AST v  programovacím jazyce PHP

The thesis provides theoretical base for development of the DoXRef. DoXRef is a tool for generating the "x-ref" documentation from PHP source codes. As part of the thesis the tool has been developed and shows the conclusions from this work in practice. There is described the reason of choosing this topic and the arguments for the development of the DoXRef in the introduction. Theoretical part describes structures for analysis and modification of the source code. Thesis extends the abstract syntax tree structure by removing some of its drawbacks. In the chapters about parsing, the Pratt's algorithm is noted, which itself is simple to understand but still very effective. This algorithm is used in the project's parser as well. The practical part describes structure and features of the DoXRef tool and includes screenshots from the generated documentation as well. The source code and usage examples are provided as a part of this thesis. The contribution from this thesis is primarily the DoXRef tool. The tool can be extended into usable form and its parts can be reused in other applications. The source code is published under open-source license.
