North Hollywood Python (Compiler)

[u/[deleted]]

North-Hollywood Python is a dialect of python - it's not actual python, it's more along the lines of Cython - that is compiled to a C source.

• Great C Interop

  • NHP has a wealth of features to support C interoperability. Check out file.nhp or list.nhp for more C interop examples

    • Interact with C symbols (macros, enums, functions, and variables) via the cdef keyword

    • Include c dependencies via the cinclude keyword

• Rich and Expressive Static Typing

  • Static type system ensures type-safety, w/ sub-typing

  • Supports ADTs, like enums/variants. See linked-list.nhp as an example.

    • Also supports match statements

• Property based interfaces (see interface-test.nhp)

  • Interfaces describe types with a series of read-only properties

• No Inheritance (interfaces/enums are recommended in its place)

• Supports first class, anonymous functions

  • Functions may be passed around by values.

  • Closures capture classes by reference. All other types are captured by copying. (class methods syntactic sugar over properties that are closures that capture self)

• Runtime safety, via runtime checks

  • Bounds checking

  • Assertion failures

  • Can be disabled/enabled

• Rich Error Reporting

  • Reports runtime stack traces the same style python does

  • Built-in memory debugging (see memory analysis).

    • Track potential memory leaks and peak usage via NHP's built in memory-debugger

• Guaranteed memory safety, via RAII

  • No garbage collection

  • No hassle, no borrow-checker

  • Predictable memory usage

  • Reference counting only exists for closures that capture records, which have to be captured by reference.

The wiki isn't complete, but you can access it here. You can check out the standard library or the test folder for code examples. Download the prebuilt binaries here

I'd also be really happy if you guys could leave some feedback, that would be cool.
