The GNU Bison tool, which uses the LALR(1) method and Generalized LR method, and the ANTLR tool, which uses the more modern ALL(*) method, are examined in detail. To compare the effectiveness of these tools, a parser for a fictional programming language is implemented using them to demonstrate the strengths and weaknesses of each approach. As the results, GNU Bison is much more powerful, but the ANTLR outweighs it in terms of implementation friendliness and functionality. The results of this thesis can help deciding which approach or tool to choose when implementing...
