MERLAN: Multimodal Environment Requirements Language

Generate the ANTLR code

In order to generate the ANTLR code (parser, lexer, visitor...), run the following script (we already provide the generated files, so this step is not necessary):

./scripts/generate_antlr.sh

This script will generate the following files into the generated folder:

• MERLAN.interp
• MERLAN.tokens
• MERLANLexer.interp
• MERLANLexer.py
• MERLANLexer.tokens
• MERLANListener.py (not used, we use a custom visitor instead, in BESSERGenerator.py)
• MERLANParser.py
• MERLANVisitor.py (not used, we use a custom visitor instead, in BESSERGenerator.py)

The parser is in charge of verifying the provided .merlan code is syntactically correct and conforms to the DSL grammar (MERLAN.g4)

We use a custom visitor, BESSERGenerator to generate executable Pyton code from the .merlan code.

Generate BESSER (Python) code

Run the following script to evaluate a .merlan file and generate BESSER code:

./scripts/merlan_to_besser.sh

(You can modify the input and output file paths)

This script will run the main.py file, with the provided arguments.
