B0

B0 is a small compiler toolchain with a deliberate two-stage pipeline:

C-like source (.c)
        |
        v
     B0 compiler
        |
        v
   binary text (.b0)
        |
        v
 B0 native backend
        |
        v
Windows x64 PE (.exe)

Install from npm

After publishing this package under the package name you choose:

npm install -g b0-language

The package exposes the b0 executable through npm's bin field, so a global install adds the command to npm's global executable path. On Windows, npm normally wires this into the PATH used by the shell after installation.

Check:

b0 version

Commands

Compile C-like source to a .b0 program:

b0 input.c output.b0

Compile C-like source directly to an executable. B0 checks for GCC first; when GCC is available it is used to build the .exe. If GCC is not installed, the built-in Windows PE backend is used instead:

b0 input.c output.exe

Compile .b0 to a native Windows x64 executable:

b0 output.b0 output.exe

Run .b0 directly with the built-in VM:

b0 run output.b0

Example

examples/hello.c:

int x = 10;
int y = 20;
print("Hello from B0!\n");
print(x + y);
print("\n");

Then:

b0 examples/hello.c hello.b0
b0 hello.b0 hello.exe
hello.exe

The generated .b0 file is intentionally plain text containing only 0 and 1 plus a final newline.

B0 v0.1 language

Supported source constructs:

• int variable declarations
• variable assignment
• print(...)
• integer arithmetic: + - * /
• parentheses
• quoted strings with common escapes
• // comments

This first release is intentionally small. The native backend turns the program's VM-visible output into a self-contained Windows x64 PE console program. More advanced B0 instructions, control flow, functions, and a real native code generator are planned for later versions.

Development

Requirements:

• Node.js 18+
• npm
• TypeScript compiler

Build:

npm install
npm run build

Test:

npm test

Check the npm package contents:

npm pack --dry-run

Publish after logging into npm and choosing a package name that is available:

npm login
npm publish --access public
