Hi, all!
This is LWDR (Light Weight D Runtime) It is a ground-up
implementation of a D runtime targeting the ARM Cortex-M
microcontrollers and other microcontroller platforms with
RTOSes (Real Time Operating Systems).
It doesn't, and possibly may not, support all D features in
order to make it viable for the constrained environments. For
example, all memory allocation is manually done via `new` and
`delete` - no GC.
It works by providing a series of barebones API hooks (alloc,
dealloc, assert, etc) (defined in `rtoslink.d`), which you must
implement and/or point to your RTOS implementation.
It can be compiled with either GDC or LDC and it is DUB
compatible.
It has so far been successfully run on a real STM32F407.
LWDR currently supports the following language features:
- Class allocations and deallocations (via new and delete)
- Struct heap allocations and deallocations (via new and delete)
- Invariants
- Asserts
- Contract programming
- Basic RTTI (via TypeInfo stubs)
- Interfaces
- Static Arrays
- Virtual functions and overrides
- Abstract classes
- Static classes
- Allocation and deallocation of dynamic arrays
- Concatenate an item to a dynamic array
- Concatenate two dynamic arrays together
- Dynamic array resizing
The following features are experimental:
- Exceptions and Throwables (so far are working on GDC only)
Not supported:
- Module constructors and destructors
- ModuleInfo
- There is no GC implementation
- TLS (thread local static) variables
- Delegates/closures
- Associative arrays
- Shared/synchronized
- Object hashing
- Other stuff I have forgotten :(
It is beta, so expect bugs.
Great work!
