Ah gotcha, now i need to go about trying to figure out how to write a clipped line routine...

You can try this.  They even have pseudo code :)

Could there be a 2nd line routine for those who absolutely want clipped ones? Or maybe someone could write an Axiom.
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

This might have been asked before, but it would be nice to be able to put code inline. That way, if you're only executing the routines once, you can save the 15 byte call.

Could buffer operations be extended to support buffer arguments? I don't think I urgently need it, but I'm sure others would like it. And since all the commands already exist, it would be best not to have to make whole new copies of all the commands with Axioms. Most of the current routines would handle it with no problem. I guess the question is how hard/time-consuming it would be for you to implement it? Variable buffers would play nice with all of the following commands.

  • ClrDraw
  • DispGraphClrDraw
  • StoreGDB
  • StorePic (the destination buffer would have to come first and in hl, so an ex de,hl would need to be added)
  • RecallPic
  • DrawInv
  • All of the screen shifting commands
  • All of the pixel commands
  • Line()
  • Rect()
  • RectI()



EDIT: Completely unrelated, but how did you come up with 1900 and 4700 cycles as arguments to pause for approximately one second? I calculated more like 1800 and 4500 for 6.0MHz and 15.0MHz, or about 1850 and 4600 for 6.15MHz and 15.4MHz (which is about how fast my TI-84+SE runs I believe).

What do you mean? Axe 0.4.5 and above support stuff like GetCalc("prgmNAME").

Is this why my screen is extremely glitchy?

First of all, the most you can save by making a call inline is 4 bytes.  3 For the call, and 1 for the ret.  But many of the routines are better optimized with conditional returns and so you would often save even less than that if you were able to save anything at all.  It's a little too small of a savings to justify the complexity of another pass I think.

Runer, I have no idea how I got those numbers.  My calculator says 1800 as well.  I think I might have been compensating for interrupts, but compensated the wrong way.  I'll change it.

Would variable buffer support be slower?

I'd like to request de-referencing routines, so I could dereference a label, or (even better) dereference something like DispGraph.

This is available for Axioms.  You would have to use inline assembly to call them anyway if it was in pure Axe so this system makes it more convenient as a whole.

Seconded (no pun intended)

new "EndIf" and "End!If" instructions

This would be awesome :D

@Runner, I was thinking of having "While 1" and "Repeat 0" to auto optimize to no code at all so that would take care of the Do part.  The end condition might work if I add new "EndIf" and "End!If" instructions (which only work on while/repeat loops).  It would be pretty cool too because it would mean you can have pre-check and post-check for the same loop!  Something I haven't seen yet in other languages...

That would be pretty nice. What about having just While and Repeat be the same as While 1 and Repeat 0?

Quigibo, would you go for grayscale routines that are 5 bytes and about 33 cycles larger, but work with interrupts? I may be wrong, but I believe this could be done by changing the start and end of the routines like so:

Code: (Current routine) [Select]
Start:
ld a,i
push af
di

End:
pop af
ret po
ei
ret
   
Code: (Interrupt-friendly routine) [Select]
Start:
ex af,af'
push af
ld a,i
push af
di

End:
pop af
ex af,af'
pop af
ex af,af'
ret po
ei
ret
