From what I heard, you can manufacture your own firearm which does not
subject to some restrictions, but you still can't make NFA firearm (select-

不是看枪管是滑膛还是线膛。
前装的滑膛枪是smooth bore, 但它不是专门用来打10 gauge 12 gauge
shotshell的， 所以不算shotgun;
一些.45口径手枪可以chamber .410 shot shell, 但因为主要打的是.45LC/ACP, 所以
法律上不算shotgun, 不然就成了NFA武器了。

I assume Java use the same regex engine as Perl, say NFA
then using backreferences is ok.
the perl cmd line I am using here is as following(under WinXP):

(1) Both Perl and PHP are using NFA, check J. Friedl's book MRE.
(2) You might be right in theorem, while in the real life, different
regex flavors have embedded different functionalities into their
engines, no need to following the dogma in the book.
(3) Regex flavors like Perl and PHP support dynamic regrx constructs,
which makes them more powerful than many other languages in handling
texts.
Good luck. |

发帖数: 1879 | 45 regex is NOT going to be any easier. It will be a lot slower because
it has to construct NFA as run time.
scanf actually supports a very limited form of regex which can be
efficiently used to match input. Its regex is slightly different
from POSIX, but for most uses, about the same.
If you can master scanf, string functions (strchr, strstr, strcmp etc),
there will be rarely a need to use anything else. More complicated
stuff usually flex.

It should do the job.
You can read at least one character matching wild-card is repeated.
I can not figure out what the regular grammar would be for repetition. In
fact grep is an NFA, probably a push-down automaton.
If you can not write grammar rules, the language is not well defined,
possibly incomplete and leaving bug in programs.
