nullc Build Status Build status codecov.io

nullc is a C-like scripting language with advanced features such as function overloading, operator overloading, class member functions and properties, automatic garbage collection, closures, coroutines, local functions, type inference, runtime type information, modules, list comprehension, generic functions and classes, enum and namespaces.

Language is type-safe and there is no pointer arithmetic.

Library can execute code on VM or translate it to x86 code for fast execution. SuperCalc is language IDE with code colorizing and simple debug compatibilities.

Changes in 2015

Core:

  • Improved type inference in short inline functions

Misc:

  • Fixed bugs, crashes and hangs in the compiler found by extensive fuzz-testing
  • Fixed compilation with gcc and clang on x86/x64

Changes in 2013

Core:

  • 'explicit' function argument types to opt-out from implicit conversions in overload resolution
  • function overload resolution based on function return type

Misc:

  • std.string module for string operations
  • std.event module for C#-style event handlers
  • Android support (armeabi, armeabi-v7a and x86 targets)

Interface:

  • nullcGetGlobalType to get nullc type id by name

Changes in 2012

Changes from 0.9 tag

Core:

  • Type inheritance
  • Generic function specialization
  • Generic functions with explicit type specification
  • Generic type specializations for a different number of template parameters
  • Static 'if' in class body
  • Named function arguments
  • Extended typeof expression improvements
  • Allocation of any type using 'new' expression
  • Nested comments
  • Numerous bug fixes

Misc:

  • Run-time type introspection improvements
  • Wrapper for binding class member functions and class members from C++.

November 19, 2010

Changes from 0.8b to 0.9

Core:

Misc:

SuperCalc:

  • Redo support
  • Persistent undo

Translation to C doesn't work in this version, use 0.8

September 18, 2010

Changes from 0.7 to 0.8b

Core:

  • List comprehension
  • Coroutine can be used as a generator in for each expression.
  • JiT executor supports dynamic code linking and evaluation

Misc:

  • Automatic function binding under gcc and msvs.

Interface:

  • Added nullcIsStackPointer and nullcIsManagedPointer.
  • Added nullcGetFunction and nullcSetFunction.

June 18, 2010

Changes from 0.6b to 0.7:

Core:

  • Coroutines
  • Compile-time function evaluation
  • Better structure compatibility with C
  • Type constructor can be called in new expression.
  • added auto[``] type - an array with implicit size and element type. Helps GC when pointer contains objects of unspecified type.
  • nullptr can be assigned to type[``]
  • Various GC fixes and performance improvements
  • VM speedup

Misc:

  • Linux x86/x64 support
  • PS3 support
  • Documentation update

Interface:

  • Debug break actions: step over, step into, step out.
  • Global memory limit can be set
  • Further translation to C improvements

SuperCalc:

  • Added watch
  • Debug improvements: step over, step into, step out, module source code load

May 14, 2010

Changes from 0.5 to 0.6b:

Core:

  • Stack overflow exception handling in JiT
  • x86 asm optimization
  • Function override
  • eval() (VM-only)
  • Translation of NULLC code into C++ code
  • Support for unary operator +, -, ! and ~ overloading.
  • NULLC function call when executor is running
  • NULLC function call by pointer
  • NULLC function call with parameters
  • Functions with variable argument count
  • Function call of auto ref type redirection to target type
  • Ability to define arrays of non-stack types char, short and float
  • Default function argument values are exported and imported
  • Operators can be defined and overloaded in functions and classes

Misc:

  • x64 support
  • Digitalmars C++ compiler support
  • NULLC can compile code containing characters with codes over 0x7f

Interface:

  • Debugging features (call stack, stack frame contents, breakpoints (VM-only))
  • Functions for fast execution result retrieval as numeric values
  • nullcSetGlobal and nullcGetGlobal functions.
  • JiT executor parameter stack placement can be specified
  • NULLC_NO_EXECUTOR define that compiles NULLC without executors

SuperCalc:

  • Remote debugging
