I recently made vim-dyon which is a syntax highlighter and indenter for the dyon programming language. There are probably some issues with being absolutely correct (since I am not too familiar with dyon), but it seems to do a good job in terms of how it works and looks. I am new to VimScript and I am looking for mostly a critique of my VimScript.

ftdetect/dyon.vim

autocmd BufNewFile,BufRead *.dyon setfiletype dyon

ftplugin/dyon.vim

if exists("b:did_ftplugin")
 finish
endif

let b:did_ftplugin = 1

setlocal tabstop=4
setlocal softtabstop=4
setlocal shiftwidth=4

indent/dyon.vim

if exists("b:did_indent")
 finish
endif
let b:did_indent = 1

if exists("*DyonIndent")
 finish
endif

" Dyon works similar to C, but without ;.
setlocal smartindent

syntax/dyon.vim

if exists("b:current_syntax")
 finish
endif
