Hi, can any guru give some suggestion on how to develop a smart parser/
compiler
given a set of syntax definition?
By "smart" I mean the parser can skip some errors and continue, like gcc
does in some situation. I hope to learn some general principles on this
issue.
Thanks!

户口怎么会注销呢？赶快找国内的亲人帮你查查，如果你找到熟人，很容易办。你写个
委托书扫描过去，发个照片（邮寄或者扫描让国内给你去冲洗），自己写个中英文草稿
，国内那边的公安局有专门办理这个的。有关系和熟人的话，不会那么多麻烦。

For LR parsers, when a set of tokens couldn't be reduced, there is a
error. At this point, you can decided on a case by case basis to
manipulate the parsing stack or directly generate an error.
For LL parsers, if your look ahead token isn't what you expect (such
as missing ';'), you can insert this pretty easily. Usually LL parsers
is a bit easier for this kind of stuff.
I'd say don't waste your time on itt. It's really not that importat.

bison supports "error" token, you can do whatever you want.

The idea is simple: Add additional rules to track potential errors.
Like switch case statements:
switch (status)
case 0 : // do status 0
...
case 1 : // do status 1
...
case 2 : // wrong, status 2 is caused by some certain mistake
generateErrorReportOnStatus2 ();
... ...
"case 2" is an example of the additional rules.
