So I decided that I was tired of not working on the VM side of things, and rigged up a simple test harness for LLVM.
Basically, this creates the following situation:
Basically, this creates the following situation:
- getstuff() is a function defined in the native .EXE which returns a simple integer
- answer() is a function defined in LLVM bitcode at run…

At long last, the Epoch syntax for defining and initializing variables has gotten some love.
Here's how R12 Epoch looks:
Here's how R12 Epoch looks:
add : integer a, integer b -> integer c = a + b
entrypoint :
{
integer forty = 40
integer two = 2
integer the_answer = add(forty, two)
debugwritestring(cast(string…

Instead of working on changing variable initialization syntax (which is hard) I decided to make structures work again in the R12 compiler, which turned out to be more or less just as hard.
The results are pleasing, though:

structure outer :
integer foo,
inner bar

I give you Epoch, now with a much better function definition syntax:
//
// FUNCTIONS.EPOCH
//
// Compiler test for higher-order functions
//
entrypoint :
{
apply("test", debugwritestring)
debugwritestring(apply("test", mutate))
}
apply : string param, (thefunction : string)
{
thefunction(param)
}
apply : st…

I'll just leave this here:
entrypoint :
{
integer total = sum(1, 10)
printinteger(total)
}
sum : integer begin, integer end -> integer ret = 0
{
while(begin < end)
{
ret += begin
++begin
}
}
foo :
{
complex i = 0, 1
assert(i * i == -1)
}
fib : 0 -> 1
fib : 1 -> 1
fib : integer n -> …

It's been a productive weekend for Epoch! Today I got postfix entities working correctly, implemented a bunch of overload resolution logic, and made a few other miscellaneous fixes and tweaks.
As of now, at least four of the compiler test programs are passing. I still need to work through a lot of s…

Plugged away at Epoch tonight for a few hours; I'm pretty happy with the results.
The Release 12 compiler is officially generating workable bytecode now - to the point where I can run a (very small) subset of the compiler tests in the VM.
One of these tests is the old "pi" program, which simply compu…

Part 3: Prototyping
The first part of creating any major project is prototyping, or at least, that's how it should be. When first embarking on an undertaking like building a major piece of software, it is essential to scope out the size an…

So after the little existential whine-fest about Epoch a few days ago, I've found myself miraculously rejuvenated.
I credit this to two things. First, I started writing about the development process, which got me thinking about what's left to do and how much I really want the language. Second, I att…
