[![Build Status](https://travis-ci.org/bakpakin/dst.svg?branch=master)](https://travis-ci.org/bakpakin/dst)
dst is a functional programming language and vm. It is a variant of
Lisp with several native useful datatypes. Some of the more interesting and
useful features are first class functions and closures, immutable and mutable
hashtables, arrays, and bytebuffers, macros, tail-call optimization,
and continuations. The runtime and
compiler are written in C99.
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

## Compiling and Running
To build the runtime and run test, run
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
```sh
cd somewhere/my/projects/dst
mkdir -p build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make
make test
