North Hollywood Python

Welcome to the North-Hollywood Python, a strongly-typed, memory-safe, compiled Python dialect that transpiles to human-readable C.

The benefits and features of NHP are the following:

• Guarantees memory safety by enforcing RAII, and executing limited reference counting for closure-captured classes
  • Unlike rust, NoHoPython reference counting - which is only used for capturing classes for closures - guarantees no memory leaks.
• Guarantees type safety via a strong yet flexible static type-checker
  • No null. Enums/Variants are used instead.
  • Enum/Variant match statements must be exhaustive.
• Supports first-class, anonymous functions
  • Functions can be passed around as values
  • Supports closures, which are functions that can capture variables outside of its lexical scope
  • No globals. Functions only can mutate arguments, and captured classes in addition to its locally defined variables.
• Code organized via a powerful module system
  • No C++-esque using namespace (prevents pollution of the global namespace)
• Runtime Saftey
  • Array access' are all bounds checked.
• Easy C interop
  • Effortless FFI interop with C, via the cdef keyword.
  • Include C headers with the cinclude keyword
• Information-Rich Error-Reporting
  • Clean, precise error messages during compile time
  • Runtime errors, such as assertion failures or index-out-of-bounds errors, are reported with their locations in the source code.
  • Reports informative, pythonic stack traces (not only for user-defined, NHP functions but also for calls to foreign C functions)
  • Built-in memory debugging that can report memory leaks
