This is a simple assembler for the Hack assembly language, written in Rust. The assembler can be used as a cli tool or as a library in your Rust project. Rhasm requires the input file to be a valid Hack assembly file, and it will output a Hack machine code file. The assembler supports all Hack assembly instructions, including A-instructions, C-instructions, and L-instructions. An example of a valid Hack assembly file is included as sample.asm
.
To install the cli tool make sure cargo is installed (you can install cargo from here), then run the following command:
cargo install rhasm
To use the library in your project, add the following to your Cargo.toml
:
[dependencies]
rhasm = "0.1.0"
Or you can use cargo to add the dependency:
cargo add rhasm
Then import the library in your project:
use rhasm;
let asm = rhasm::Assembler::build(&in_file, &out_file);
// Then you can use the asm object to assemble the file
Rhasm exposes two ways to assemble Hack assembly code, the first is through a binary cli tool and the second is through a library.
To use rhasm as a cli tool, you can run the following command:
rhasm <input_file> [-o | --output <output_file>] [-d | --disassemble [--with_symbols <symbol_file>]]
