Web Application for Relational Calculus Queries

Welcome to RC-Evaluator: A User-Friendly Tool for Evaluating Relational Calculus Queries.

RC-Evaluator depends on MonPoly which can be found here: https://bitbucket.org/monpoly/monpoly/src/master/ and on React found here: https://react.dev/

If you just want to run RC-Evaluator locally and have node.js installed just

1. Clone the git repository
2. Go to the vis directory
3. Run

   npm install
   npm start
   

If you want to build and make changes to RC-Evaluator you will need an OCaml compiler. If you don't already have one installed we recommend using OPAM: https://opam.ocaml.org/doc/Install.html to install.

You will also need the MonPoly library: https://bitbucket.org/jshs/monpoly/src/master/

To build RC-Evaluator on your local machine follow these steps:

1. Clone the monpoly directory
2. Git clone RC-Evaluator
3. Copy the rcEval.ml file from RC-Eval/bin into monpoly/js.
4. From monpoly run:

   eval $(opam env)
   dune build
   

5. Copy the rcEval.bc.js file located at monpoly/_build/default/js/rcEval.bc.js into RC-Eval/vis/public
6. From RC-Eval/vis run:

   npm install
   npm start
   

Every time you make a change to the monpoly library you will have to repeat step 4-6 (you only have to run npm install once)
