An Emacs major mode for writing 6502 assembly code specifically for the ca65 assembler.

• Extremely strict indentation. Labels and any line that starts with a period (e.g. .proc, .scope) are on column 0. Everything else is indented to the column specified in the custom variable ca65-mode-indent-width. Why so strict? I don't know enough about writing major modes to ease the restriction and this is the indentation I currently prefer. Help me make it better!

• Syntax highlighting. I'm new to this to, but I have been able to get pleasing enough syntax highlighting for my tastes. I'm not sure if I'm doing it right, but it works!

I don't know how much it will do in the future, but it doesn't do any sort of syntax checking or provide any special functions or commands to run that may be helpful while writing 6502 assembly. Perhaps in the future.

I am very open to suggestions, ideas, and contributions, so pitch in!

I found these articles and pages very helpful while researching how to even create a major mode in the first place. If you want to write your own major mode, hopefully these will help you, too. In no particular order:
