Virgil Dupras f0cbda1f2e tests: add Forth tests 
Modest first step
 2020-03-19 15:43:48 -04:00
Virgil Dupras b335e538b4 Move "forth" folder to project's root folder 
It's not really an App.

Virgil Dupras 1df9c4fc1b forth: split forth source into multiple files 2020-03-17 21:44:32 -04:00
Virgil Dupras 549cf74e9d forth: inline code from "apps/lib" 
Forth-ification of Collapse OS goes forward. What will happen is that assembly
code in apps/ will become Forth code. The concept of an assembler code library
will become obsolete.

However, Forth's core use some of that code. To facilitate the transition, I'm
inlining that code directly in Forth's code.

Virgil Dupras c3838714d5 forth: improve execution model 
My approach with RS was slightly wrong: RS' TOP was always containing current
IP. It worked, but it was problematic when came the time to introduce
RS-modifying words: it's impossible to modify RS in a word without immediately
messing your flow.

Therefore, what used to be RS' TOS has to be a variable that isn't changed
midway by RS-modifying words. I guess that's why RS is called *return* stack...

Virgil Dupras a8e573c84a forth: add bin dict compilation stage! 
Big one.

This allows us to write higher order words directly in Forth, which is much
more convenient than writing post-immediate (see "NOT" structure in diff if
you want to see what I mean) structures in ASM.

These structures can then be written to ROM (rather than loaded in RAM for
definitions loaded at run-time).

That's quite a bit of tooling that was added, 2 compilations stages, but I
think it's well worth it.

Virgil Dupras 6224ea2fe9 zasm: use printcrlf instead of hardcoded CRLF 2020-02-23 18:52:25 -05:00
Virgil Dupras 0f2b3aca24 zasm: allow zasm to omit its 3rd argument 
A bug in rdWS made zasm error out when omiting its 3rd argument.

fixes #90
 2020-02-18 15:46:55 -05:00
Virgil Dupras e1e0676191 emul/hw/sms: add A/B ports and a Genesis pad 
This makes the emulator suitable to run the base SMS recipe.
 2020-01-10 21:20:44 -05:00
Virgil Dupras b60252e330 emul/hw/(ti|sms): detect window being closed 
Previously, it would never get out of the event loop.
 2020-01-10 16:59:48 -05:00
Virgil Dupras 66744c0026 emul/hw/(ti|sms): fix compilation with gcc 
It seems to be picky about where it accepts its link flags.
 2020-01-09 08:36:29 -05:00
Virgil Dupras 6acd22492c emul/hw/sms: WIP 
VDP kinda works. Can see the Collapse OS prompt with SMS base recipe
if `STDIO_GETC` gets replaced with infinite loop (no input emul yet).

Virgil Dupras c7ef8bf915 recipes: add "make emul" targets where appropriate 2020-01-02 16:59:38 -05:00
Virgil Dupras 9216057db8 emul/hw: add TI-84+ emulator 
I implement the screen using XCB which is much more friendly
than z80e's SDL+CMake for development machines that want to install
minimal dependencies (for example, a port-less OpenBSD rig).

Virgil Dupras 25fc0a3c72 Add RC2014 classic emulation 2019-12-31 22:03:48 -05:00
Virgil Dupras 097c677641 emul/zasm: use libcfs 
This allows us to get rid of the zasm.sh wrapper.

Virgil Dupras 4cde58fd83 cfspack: make into a library 
Use it in shell instead of using popen()
