Much to my chagrin, I realized earlier this evening that tuple members are being stored backwards in memory.
This is because of some laziness on my part in the grammar. Function parameters are passed in reverse order (i.e. the first parameter gets pushed onto the stack first, and the last parameter …

Tuples are most of the way implemented in Epoch now. I'm continually (and pleasantly) surprised by how much easier it is to do things than I would have guessed. Thus far most of the language features have taken far less time to implement than I would have predicted.
So either I'm making a monumental…

I had a quick ponder earlier today about what all would be necessary in order to write a full Win32 app in Epoch.
Structures are obviously very widely used, so I've been planning on doing them for one of the next releases for quite a while. However, something I overlooked was function callbacks. I'l…

Had a few spare minutes today, so I hacked up serialization and got it finished. Turns out it was a lot quicker of a job than I expected.
I also decided not to serialize directly to a binary format. Instead, the serialization process outputs an assembly language file that targets the Fugue virtual m…

Alright, ladies and gents, it's time to clip the big red ribbon and unveil Epoch Release 3.
Included in today's festivities are a fully stack-based virtual machine, numerous tweaks and improvements to built-in functions, and a couple of back-stage odds and ends that you probably won't notice unless …

Had a quick hack on Fugue again this afternoon, and finally got everything working the way it should be with regards to the stack. One case I had missed was recursion; because of the way the bytecode is stored, it was possible for a recursive function to obliterate its parent call's stack informati…

I think I'll be posting Epoch Release 3 soon; I'd like to do some documentation work, and a bit of assorted cleanup, but once that's done, R3 will be ready to go. The big changes are of course related to making the VM stack-based rather than the old mutant thing it used to be [grin]

We're back on the air, baby!
As of some unholy hour this morning, I've gotten all the relevant stack-based changes made, so that the guessing game works once again. The pi computation program should be mere hours behind, but there's been a complication.
A lot of core-level guts have changed in the Fu…

I decided to take a few spare minutes and get back into working on Epoch, particularly on making things purely stack-based.
So far, so good; almost all of the arithmetic operations and other built-ins have been removed, awaiting reimplementation in stack-aware forms; but other than that, everything …

English is such a weird language. We can burn something up, burn something down, burn it in, or even burn it out. The semantics of the burning are modified entirely by the preposition. Some prepositions invoke literal flame, others give us a more metaphorical image.
