Technical Information

Sink development started in March of 2016.

Language design:

Imperative/procedural
Dynamically typed
Garbage collected
Lexical scoping
Static binding with robust namespacing
A mixture between shell scripts, Lua, and a bit of Lisp

Both implementations:

Virtual machine with a big switch statement
Register based VM with 256 registers per stack frame
Lexer, parser, code generator, and VM are stackless and can be paused at any moment
Tail call optimization supported
REPL supported
All I/O is governed by the host
Designed for asynchronous use, with ability to pause execution at any time
Almost identical embedding API between implementations

C99 implementation:

Values are stored via NaN-boxing
Simple stop-the-world mark sweep garbage collector
Easy to build, just two files: sink.h and sink.c
Asynchronous commands via simplified Promise-like objects sink_wait

TypeScript implementation:

Values are stored as JavaScript values null, numbers, strings, and arrays
Relies on the native JavaScript garbage collector
Asynchronous commands and I/O via JavaScript Promises
