Objective: This document is not an introduction to parser generators. Readers should rather have a good understanding of them, especially of LALR parser generators. This document merely describes the main aspects of the implementation of a LALR parser generator named wisent. It is divided into a concise description of the programming interface and an overview over the data structures and specifics of the implementation of the wisent parser generator.

The Master thesis is focused on creation of an editor of CodAL language for the development toolkit of the project Lissom which is based on Eclipse framework. The goal of this thesis is to analyze the problem of editor creation and the features in existing editors which add some value to their usability. The outline of parser creation and subsequent code analysis of the source codes written into the editor is described in the theoretical part. It also explains the syntax and semantic aspects of the CodAL language. In the practical part the new CodAL language editor is designed and developed. The new CodAL language editor integrated into the development toolkit of the project Lissom is the final outcome of this thesis.
