vim-ca65

Syntax highlighting for the ca65 macro assembler with MatchIt support.

Installation

Install via your plugin manager of choice. For example, with vim-plug:

call plug#begin()
Plug 'stove-panini/vim-ca65'
call plug#end()

Then, call :PlugInstall

Instruction sets

This plugin supports instruction sets for all of ca65's supported CPUs:

• 6502
• 6502X (6502 w/ illegal instructions)
• 65C02
• 65CS02
• 65816
• HuC6280
• 4510
• sweet16

Filetypes

The base "ca65" filetype highlights the original 6502 instructions. For the variants, append its name after a dot when setting the filetype. For example, set ft=ca65.65C02, set ft=ca65.HuC6280, etc.

This plugin does not contain an ftdetect script nor does it enforce any particular indentation scheme. That's all a bit too personal! It's easy to set your own, however.

Setting your own filetype detection & options

In your vim config as an autocommand:

augroup ca65
  au!
  au BufNewFile,BufRead ~/Projects/nes/*/*.asm setlocal ft=ca65
  au BufNewFile,BufRead ~/Projects/pce/*/*.asm setlocal ft=ca65.HuC6280
  au FileType ca65* setlocal noexpandtab ts=4 sw=4
augroup END

Or as a modeline at the top or bottom of each file: ; vim: ft=ca65.sweet16 ts=8 sw=8

Thanks

At the time of this writing, there are two other existing vim plugins for ca65, maxbane/vim-asm_ca65 and MatthiasQuintern/vim-ca65. Big thanks to them for inspiring some of the design decisions. I also referenced Vim's syntax plugin for xa65 quite a bit as well.
