This provides a collections of types and methods for emulating the Machester Baby the first program stored computer; this was the first machine to have RAM and thus the first to execute software, providing a familiar (abeit, primitive) programming environment to anyone familiar with modern assembly programming, this library can be included in a variety of software and platforms allowing emulation functionality of this historic machine.
The core of this library is core::BabyModel, this struct has
fields representing all of the Baby's internal registers and
32 word memory, you can initialise this struct with an array of
i32 (the Baby performed 2's compliment arithmetic) and a size
of 32, this array can contain the program instructions starting
at position 0 (see core::instructions::BabyInstruction for
documentation on operands).
```rust use babyemulator::core::BabyModel; use babyemulator::errors::{BabyError, BabyErrors};
fn main() { let model = BabyModel::newexampleprogram(); let mut lastmodel = BabyModel::new(); let mut result = model.execute(); while let Ok(newmodel) = result { lastmodel = newmodel.clone(); result = newmodel.execute(); } match result { Err(BabyErrors::Stop()) => println!("{}", last_model.accumulator), _ => println!("Something went wrong. ") } } ```
