xasm
A cross platform, compiled and dynamically typed programming / intermediate language
Xasm is meant to be an intermediate representation for compiled and dynamically typed programming languages. However, xasm is still itself suitable for scripting.
Features
- Dynamic typing
- Lua-like speeds
- An easy to use Rust foreign function interface
- First class support for Functional and Object Oriented programming
- Simple syntax
Documentation
You can find the virtual machine's documentation here, and the compiler backend documentation here. Both of these components are called xmachine
and xassembler
respectively, and you can find them on my GitHub account.
$ xasm

Compiler for the xasm programming language
USAGE:
xasm [SUBCOMMAND]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
SUBCOMMANDS:
compile Compile a xasm file
help Prints this message or the help of the given subcommand(s)
run Run a xasm file
Examples
Here's how you implement basic control flow structures in xasm.
value = 1
if value {
println("`value` is not 0")
} else {
println("`value` is 0")
}
while 1 {
println("Still looping!")
}
Keep in mind that xasm is intended to be an intermediate representation!
Object Oriented Programming
To write object oriented code in xasm, first you write a class.
class Point {
fn new(self, x, y) {
self.goto(x, y)
self
}
self.goto(self, x, y) {
self.x = x
self.y = y
}
}
The new
method is typically used to instantiate an object, but you can write other constructors if you'd like. The reason we use the new
method is because the new
function will call our class's new
function to construct our object.
Here's how we would construct our Point
.
p = new(Point, 2, 3)
Functional Programming
Because xasm supports closures, you can easily implement church encodings.
fn True(a) {
fn(b) { a }
}
fn False(a) {
fn(b) { b }
}
fn If(c) {
fn(a) {
fn(b) {
(c(a))(b)
}
}
}
In addition, you can use more practical functional programming techniques.
multiply = fn(n) {
fn(m) {
mul(n, m)
}
}
double = multiply(2)
triple = multiply(3)
println(double(3))
println(triple(3))
