I'm very happy to say that parsing a mathematical expression is almost done!

It now 'chains' operators, i.e. A*B+3, instead of the seperate routines for A*B and A+3 for example. Out of the 14 booleans/operators (+ - * / or xor and -> => <= > < = !=) I've finished 10. I only need >= <= > < to do, and after that, I'm ready with parsing such string (yet without functions). I haven't implemented auto-opt yet, but I will definitely do. Here is an example of what it can do:
String = A+4*B/(1-C)+3
Output =

Code: Select all: ld a, ($D05301) ; B add a, a add a, a push af ld a, 1 ld hl, $D05302 ; C sub a, (hl) pop hl ld l, 1 mlt hl call _DivHLByA ld a, l ld hl, $D05300 ; A add a, (hl) add a, 3 ret

The only good optimization I see is replacing the "push af" with "ld h, a" and remove the "pop hl".

good job, I'm waiting for your first release...

I DID IT!!!!!!!!!

I'm so happy now

I succesfully compiled a normal program, without any errors

Ofc, I've finally a gif for you guys!

The program is still far from perfect, but I'm more than happy with this now

Congratulation, is there a link somewhere to download the program? I would like to know how does it work, or if you don't want to share the code, just try it

Good job!

Good job!

I haven't uploaded it yet, because v1.0 is not ready. You want to know how this works? Well, ofc I can explain it! It reads the program line by line. For example, if it reads a "ClrHome", it adds the corresponding code to the program data, and continues with the next line (if there is one). Or it reads the If-token. Now it first expresses the remains of the line (after the If-token), adds that to the program data, pushes some values here and there, and reads the next line. If that is a "Then", it pushes an End (kind of), and otherwise, that line will be parsed, and the values will be popped, because the If-statement is over. That is basically how it works. Hope that that is enough
