tsoding/b: Compiler for the B Programming Language implemented in Crust

Compiler for the B Programming Language implemented in Crust

• Rust – the compiler is written in it;
• fasm – used as the compiler backend;

$ make
$ ./build/b -run ./examples/hello_world.b

Also check out more examples at ./examples/.

The project comes with btest utility which tests the B compiler. It is built automatically along with the B compiler when you do make.

When you run it, it just builds and runs all the tests from the ./tests/ folder on all the supported targets and generates a matrix report. Give it a try to see it for yourself:

It doesn’t crash when it encounters errors, it just collects the statuses of the tests on all the platforms to give an overview of the current state of the compiler.

If you want to test only on a specific platform you can supply the flag -t

$ ./build/btest -t fasm-x86_64-linux

You can supply several platforms

$ ./build/btest -t fasm-x86_64-linux -t uxn

If you want to run a specific test case you can supply flag -c

You can do several tests

$ ./build/btest -c upper -c vector

And of course you can combine both -c and -t flags to slice the Test Matrix however you want

$ ./build/btest -c upper -c vector -t fasm-x86_64-linux -t uxn
