	[[Category:~~GSOC2009~~]]		== Project description ==

			Goal of this project is to create a prototype implementation of possible new ASCEND
			compiler. Current compiler is highly effective, coded using Flex/Bison, but has a huge and
			difficult code, that is hard to understand and extend. Being a critical part, compiler code
			needs to be high quality with no (or least possible amount of) errors and bugs. That is still
			harder to achieve in current vast situation. Using more modern language description and
			parser generation tool like ANTLR, the listed issues can be resolved. ANTLR, having very
			good GUI-based development environment, active community and various output languages
			can result in a modular, maintainable and fast compiler. Additionally, some of the
			objectives of next-generation ASCEND syntax can be incorporated in the solution and tried
			out.

			== Tasks ==

			Create ANTLR parser of ascend4 language - rewrite Flex/Bison rules to more readable
			ANTLR'sExtended Backus-Naur Form. By doing this, obtain an AST (Abstract Syntax Tree
			). This will also result in getting rid of much of the code behind Bison rules. Pass the AST
			to ANTLR-created semantic analysis filters. Additionally, extend the existing parser with
			next-generation parser ideas - at least some syntax ideas like respelling the pedantic
			keyword style, moving the language to look more like modern programming languages, etc.
			Create tree walker converting ascend4 tree to the extended grammar trees. Test the solution
			on a reasonable amount of test input. If there is time left, start incorporating the solution
			into the existing C-based system.

			== Milestones ==

			Finish the ascend4 parser including semantic analysis filters by mid-term. By the end, test
			the parser thoroughly and work on the new ideas. Complete as many as possible, resulting
			in a solid and compact prototype for a new compiler implementation.
