The North-Hollywood Python Compiler

A strongly-typed, memory-safe, compiled dialect of Python, that transpiles to human-readable C.

• Guarentees memory saftey 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 - guarentees no memory leaks.
• Guarentees type saftey 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 it's lexical scope
  • No globals. Functions only can mutate arguments, and captured classes in addition to it's locally defined varaibles.
• Code organized via a powerful module system
  • No C++-esque using namespace's(prevents pollution of the global namespace)
• Runtime Saftey
  • Array access' are all bounds checked.
  • No Undefined Behavior, despite targeting C
    • Sequence of evaluation is guarenteed
• 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 faliures 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
