xemmai is a dynamic programming language. Its syntax is based on the off-side rule. Closing parentheses, brackets, and braces can be omitted where they are not necessary in conjunction with indentation.
Here is how it looks like:
system = Module("system"
print = system.out.write_line
hanoi = @(towers, move)
step = @(height, from, via, to)
height > 1 && step(height - 1, from, to, via
move(from, to
height > 1 && step(height - 1, via, from, to
step(towers[0].size(), towers[0], towers[1], towers[2]
towers = '(
[1, 2, 3
[
[
print(towers
hanoi(towers, @(from, to)
to.unshift(from.shift(
print(towers
Which shows:
'([1, 2, 3], [], [])
'([2, 3], [], [1])
'([3], [2], [1])
'([3], [1, 2], [])
'([], [1, 2], [3])
'([1], [2], [3])
'([1], [], [2, 3])
'([], [], [1, 2, 3])
It has lambda closures, classes, exceptions, modules, threads, and fibers.
It is implemented in C++ and has C++ friendly API to implement extension modules. It aims to be a general purpose glue language.
It runs on linux, windows, and hopefully other unix systems.
Internally, codes are executed on a bytecode interpreter. It also has a concurrent garbage collector to utilize multiple processors.
