" Vim syntax file
" Language:    Arduino
" Maintainer:  Johannes Hoff <johannes@johanneshoff.com>
" Last Change: 21 October 2021
" License:     VIM license (:help license, replace vim by arduino.vim)

" Syntax highlighting like in the Arduino IDE
" Automatically generated by the script available at
"    https://github.com/johshoff/arduino-vim-syntax
" Using keywords from <arduino>/build/shared/lib/keywords.txt
" From version: 1.8.16

" Thanks to Rik, Erik Nomitch, Adam Obeng, Graeme Cross and Niall Parker
" for helpful feedback!

" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
  syntax clear
elseif exists("b:current_syntax")
  finish
endif

" Read the C syntax to start with
if version < 600
  so <sfile>:p:h/cpp.vim
else
  runtime! syntax/cpp.vim
endif
