This project is an interpreter for a minimal form of Eiffel. This minimal form of Eiffel has only 1 data type, integer, and the only identifiers are single letters (i.e. 26 possible identifiers since Eiffel is not case sensitive).
The interpreter parses the Eiffel program and builds intermediate data structures. These data structures will are then interpreted and execute the program. The tokens in this language are separated by white space. The parsing algorithm detects syntactical and semantic errors. The first such error discovered causes an appropriate error message and prints the error while terminating the program. Run-time errors are also detected and the appropriate error message is printed and terminates the program as well.
To execute the parsing application, use the run-rast shell script accordingly: sh run-fast <file_name>
