单片机a51汇编 Vim语法脚本

这个脚本以前就写好了，一直没有时间放上来，由于没有学过 Vim 的脚本语法，可能写得有点 ws，大牛们不要鄙视啊...

不过这个脚本依然存在 bug，就是跳转指令后面的标号不能高亮，这个应该是正则表达式的问题，由于没学过，自己看了资料还是没办法接解决，希望大牛们能给点意见啊.

脚本如下：

" Vim syntax file
" Language:	MCS-51 Assembler (A51)
" Maintainer:	Killua

if version < 600
syntax clear
elseif exists("b:current_syntax")
finish
endif

添加方法：

将脚本复制到 Vim 目录下的 syntax 文件夹里面

添加到列表里面

修改 synmenu.vim

" The following menu items are generated by makemenu.vim.
" The Start Of The Syntax Menu

an 50.20.100 &Syntax.C :cal SetSyn("c")<CR>
an 50.20.110 &Syntax.C++ :cal SetSyn("cpp")<CR>
an 50.20.120 &Syntax.A51 :cal SetSyn("a51")<CR>

" The End Of The Syntax Menu

列表里面的语法脚本应该茫茫多，只要加在他们后面就可以了，至于 50.20.120，自己把握放到适当位置.
