It's very simple to use, all the required and example boilerplate is already done with scripts to automate the process.

• NodeJS
• JDK 8 or 11
• Yarn or NPM

On the root directory

yarn
# or
npm install

An script is already done, so running one command line is enough to run everything at once

yarn start [input_file.txt]

e.g

yarn start entries.txt

The script consists of three main steps

Consists of using the grammar file (src/grammars/Exp.g4) to generate the lexer and parser scripts, which will be stored in the src/antlr folder.

yarn ant

With the lexer and parser scripts created, we can then build our jvm assembly, for this we execute the compilation script, passing as argument our program.

yarn start entries.txt

Having the assembly in hand we can then assemble our program using jasmin.

yarn jasmin
