不能在Parser部分对Rule使用~操作符号

对于Parser Rule,只能使用+, *, ?
但是可以对Lexer Rule使用~操作符号
antlr的缺点之一
Submitted by gougou on Sat, 2005-09-24 15:14出于性能的考虑,Antlr没有实现完全的LL(K)解析,而是用了线性的LL(K),但是线性LLK会产生很多的不确定性。经常导致你需要将自然的Parser Rule改写为不自然的形式。
不过据说Antlr 3将提供完全的LL(K)实现,不过从目前的进度来看,感觉要到2007年能推出就不错了:(

vxworks 和 vmware
Submitted by gougou on Tue, 2005-09-13 23:50因为VxSim模拟器支持的VxWorks功能有限,因此想装一个真正的VxWorks的运行环境,最开始想到的是在vmware上装一个,这样可以比较省事,但是花了一下午的时间,在MS—DOS虚机上装出来的VxWorks一启动就崩溃了,总是不行,后来在Google上查了一下,才发现Vmware不支持VxWorks,据说Wind River开发组的人内部是用修改过的Vmware和特殊的BSP以及驱动进行的开发,可惜我拿不到那样的版本,郁闷。看来只能老老实实的找台破电脑。

Antlr的贪婪模式语法
Submitted by gougou on Mon, 2005-08-29 09:43.-noscript-blocked { border: 1px solid red !important; background: white url("chrome://noscript/skin/icon32.png") no-repeat left top !important; opacity: 0.6 !important; }
下面的规则是非贪婪模式的语法,它会匹配{之后的任意字符而不会匹配}符号,
CURLY_BLOCK_SCARF
: '{' (.)* '}'
;
要想让Antlr能够匹配},我们需要将规则改为
