RustyForth

Forth written in rust inspired from tsoding's porth.

Keywords Implemented:

• not an operator but a number (Push)

• + (Plus)

• - (Minus)

• = (Equal)

• . (Dump)

• dup (Duplicate)

• > (GreaterThan)

• if

• end

• else

• while

• do

• Others might also be added but for now the scope is limited to this

• For examples of language look into examples folder.

Running RustyForth

Same as porth, Forth has two mode. A simulation mode and a compilation mode. Simulation mode simulates program and shows its output. It is used to easily implement new feature and once it becomes a solid feature, then make the same for compilation mode.

Note: extension of input file must be .rf

• Method I

  • Simulation Mode

    cargo run sim {{ {repo_root}/examples/arithematic.rf }}
    

  • Compilation Mode

    cargo run com {{ {repo_root}/examples/arithematic.rf }}
    
    ./arithematic
    

• Method II

  • Build a release binary of compiler:

    cargo build --release
    

    the binary will be generated in "RustyForth/target/release/rustyforth"
    where RustyForth is repo's root directory.

  • Simulation Mode

    rustyforth sim {{ input_file.rf }}
    

  • Compilation Mode

    rustyforth com {{ input_file.rf }}
    
    ./input_file
    

The main aim for project was to learn rust and its mysterious ways. The assembly from tsoding's porth is taken as it is because it was not the goal of project to learn assembly. Though I did learn some.
