Pocketlang _v0.1.0

Pocketlang is a lightweight & fast object oriented programming language designed for embedding and scripting. Including the compiler, bytecode VM and runtime it's a standalone executable which is less than 300KB and the language itself can be compiled in less than 4s without any external dependencies.

Simplicity is the zen of pocketlang. The syntax is more of an executable pseudocode. Compiling the language itself takes just a single gcc/msvc command. No configuration is required to embed it in another application. pocket VM along with its compiler and standard runtime are a single executable that's less than 300KB. It's not just small but much faster with memory efficient dynamic type system, self adjusting heap for garbage collection, tail call optimization, single pass compilation etc, that makes it compete with main stream langages like python, ruby, wren and lua. And more things that makes pocketlang a swiss knife of programmers.

What it looks like

# A recursive fibonacci function.
def fib(n)
  if n < 2 then return n end
  return fib(n-1) + fib(n-2)
end

# Prints all fibonacci from 0 to 10 exclusive.
for i in 0..10
  print("fib($i) = ${fib(i)}")
end

Getting Started

Note that at the moment there isn't any releases and it's actively being developed. To get your hands dirty clone the source and build it. Compiling the language itself takes just a single gcc/msvc command. See README for more detail.
