We can do a depth first traversal of the produced abstract syntax tree +to parse in the correct order. This is in the file `Translation.java`. + +You produce a lexer and parser by running the sablecc .jar file you can download [here](http://downloads.sourceforge.net/sablecc/sablecc-3.7.zip). Then run it with the first argument as the grammar file: + +`java -jar sablecc-3.7/lib/sablecc.jar sableCCCalculator.grammar` + +(changing the paths as appropriate). The produced java files are not included in git since they're unnessicary. We compile the compiler, program stack and translator: + +`javac sableCCCalculator/*.java` + +I setup a makefil that can be used. First make sure that sablecc is extracted in the directory below `EsotericProject` and just run `make`. + +Then we can run the program. For now it only works by reading files. There are some example maths questions in the examples folder: + +`java sableCCCalculator.Compiler examples/maths.txt` + + + |
