# Brainfly

A Brainf**k JIT and AOT compiler built on top of C# type system.

Leveraged .NET generic type system and abstract static interface methods to achieve great performance.

See [Introduction](Intro.md) for details.

## Build

```bash
dotnet build -c Release
```

## Usage

```bash
dotnet run -c Release -- build <memory_size> <file>
dotnet run -c Release -- run <memory_size> <file>
dotnet run -c Release -- bench <memory_size> <file>
```

For example,

```bash
dotnet run -c Release -- build 1024 a.bf # produce a self-contained a.cs so that you can run it directly with .NET or build it with .NET NativeAOT
dotnet run -c Release -- run 1024 a.bf # running directly from source file a.bf
dotnet run -c Release -- bench 1024 a.bf # benchmark directly from source file a.bf
```
