dst
dst is a functional programming language and vm. The language is a lisp that replaces the list with other data structures that have better realworld characteristics and performance. The language can also easily bridge to native code, and native useful datatypes. The bytecode vm is a register based vm loosely inspired by the LuaJIT bytecode format.
There is a repl for trying out the language, as well as the ability to run script files. This client program is separate from the core runtime, so dst could be embedded into other programs.

- Mutable and immutable strings (buffer/string)
- Lisp Macros
- Byte code interpreter with an assembly interface, as well as bytecode verification
- Proper tail calls.
- Direct interop with C via abstract types and C functions
- Dynamically load C libraries
- REPL
Compiling and Running
Dst is built using CMake. There used to be a hand-written Makefile, but in the interest of easier Windows support I have switched to CMake.
On a posix system using make, compiling and running is as follows (this is the same as most CMake based projects).
Build
cd somewhere/my/projects/dst
mkdir -p build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
make test
The repl can also be run with the CMake run target.
make run
