Virgil Dupras bc1496a7e3 zasm emul: bring back kernel/user distinction 
It was a bad idea to remove it. Now that I'm introducing the concept of
a per-app glue file, it becomes much easier to build emulated zasm as a
userspace app.

Virgil Dupras 7fad3b0c90 Move /parts/z80 to /kernel 
Let go of that "meta os" thing. it's not as meta as I made it sound
like. It's a kernel.

 2019-05-19 09:14:40 -04:00
Virgil Dupras 98695f9912 zasm: de-index symRegister 
Make symRegister's logic pointer-based so we can break through the 0x100
limit.
 2019-05-19 09:06:24 -04:00
Virgil Dupras bccf933ea9 zasm: try for regular number or symbol before parsing expr 
Previously, we would mess up literals like '-'.

Virgil Dupras 28d5ebdc8a Make apps folder into a namespace 
To straighten out includes and to pave the way into zasm being part of
the same "include CFS" as parts, we make zasm includes namespaced.
 2019-05-17 20:22:32 -04:00
Virgil Dupras 93e40aeb09 Strip comments out of code before packing CFS 
This shrinks the CFS size to 21k from nearly 64K. This will allow me to
kick the can down the road a bit with regards to supporting storage
seek/tell greater than 64K.

I'll get to it, but first, I want to assemble zasm with zasm!

Virgil Dupras 556be3f0ce zasm: allow for whitespace inside string literals 
Also, increase scratchpad size. It wasn't big enough for some
expressions in shell unit.

Virgil Dupras 7083116379 zasm: remove JUMP_ prefixes 
They serve no purpose and make the code less flexible.
 2019-05-17 09:50:11 -04:00
Virgil Dupras 013a3b74c8 Add the concept of unit tests 
Will be much much easier to tests new core routines without having to
re-create their context first.

Also, extract parse.asm from core.asm
