I just finished getting through all the bugs I was having with my emacs mode. The mode will highlight all the z80 instructions in either all caps or all lowercase, highlights all the registers (unless I missed some, which would be easy to fix), colors numbers a special way ($FF, 0FFh, %11111111, 11111111b, and 255), colors the special $ that refers to the current position, colors the ./# preprocessor directives, colors labels, and it will auto-tab out your code. The last part means that if you start at the beginning and press tab on each line, it should (in most cases) tab it to the correct place. It will push out on pushes and in on pops. If you put a space on the line you are tabbing, it will let you go to whatever indentation level you want, and all the other code that follows will start at that indention. The way I've found to be useful for this is to just go to the beginning of your instruction ("ld" for instance), but a space before it, and tab to the correct indentation, and the press backspace to delete the space.

To use it, you copy the code below into a file (I called it z80-mode.el), and put it wherever you want (I put mine in ~/.emacs.d/), then you (load) the file in your .emacs file. For instance, the relevent line in my .emacs file looks like:
Code:
The mode will automatically pick out .z80 files and work with them. To make a .asm file use this mode, you would do: M-x z80-mode RET. You could also change the line that looks like:
Code:
to
Code:
And it will pick out .asm files to work with, also.

That should be everything, so here is the code:
Code:

Looks great, Tanner.

Wow, you did an extremely complete job on that! Did you submit it to ticalc.org, where I think it would be a good addition for those of us who still code with terminal text editors? If only I used emacs, I would totally use this, but I'm afraid my sanity insists on vim (in large part because that's what I learned as a fledgling Linux nublet). I hope this most of all helps you, though, so we can see more cool ASM programs from you soon!

I'm hoping it helps with my programming! If I get a chance, I'll upload this screenshot I took of your source code with highlighting and tabbing and such (If it is fine with you, at least). And I actually hadn't thought of uploading it to TICalc.org, so I think I'll do that a little later today. I'll have some time later today to just program without the Internet, so I might actually get something done \o/

Vim is better.

Sorry for necroposting but I want to use this mode and continue to update it if possible:

This line:
Code:

Should be
Code:

Otherwise you'll have a darn annoying time writing capital r (R)..

This is probably just a first update, more to come possibly.
Another thing I've noticed is that if you tab anywhere on a line, the thing that gets indented is the whole line instead of where you indent from, will try and change that too.

Regarding that last point, I'd prefer tabbing to indent the entire line if you're still typing the opcode and operand(s), but to insert a tab if you've finished writing the opcode and operand(s) and are tabbing over to add a comment. I don't know how feasible that is, though.

Yes, but if you want to align comments for example, that would be really annoying. And that's when you need it because with the mode, you indent correctly automatically.
Oh, yeah, another thing:
Macros/Variables shouldn't be indented, which they will be with this mode.

EDIT: I guess that last thing was unnecessary to comment on, I just commented (ugh, bad pun) the line with the ret (that I changed previously) out.
Now it won't do that anymore!
(Unenthusiastic) yay..
So now to figure out how to fix the "indent from start of the line" problem, then I'm calling it done..
I tried just commenting the line with (beginning-of-line) but that didn't really change much..

EDIT 2:
Ah, I went mad (insane) at a point so I deleted the indentation function from the z80-mode function, lo-and-behold.... it worked.
What the flippy-floppy..
So here's the final result if you don't want to have the mwim package, just comment out the two keymaps that uses is and the require for it, otherwise installit this way M-x Package-Install RET mwim RET

Code:
