Subject: [regex-coach] Need a Regex to return multi result if matching more
	than one times
Message-ID: <BANLkTi=BJATnnA9A=MhP7h+ZtGhJFBgtCg@mail.gmail.com>

Hi all,

I want a  regex used in Perl which is

@ret = $query =~ /(googl.?)|(.?oogle)/;

if the $query is "google",  then will be matched, and the @ret = (google,
undef), $1 = "google", $2 is undef

but I want result like @ret = (google, google), because the
pattern  "(.?oogle)" is matched too,

And my regex is very long (the regex above is just an example), maybe
thouands of "|", so if separate the regex  to /(googl.?)/ and /(.?oogle)/
will be inefficient.



Does anybody can help me?  Thanks!

Subject: [regex-coach] Regex Coach \K option fails?
Message-ID: <4DF65A0E.7050009@illsoft.com>

 From the PCRE docs:

The escape sequence \K causes any previously matched characters not to 
be included in the final matched sequence. For example, the pattern:

          foo\Kbar

matches "foobar", but reports that it has matched "bar".

http://www.pcre.org/pcre.txt


This fails in The Regex Coach. Why?

Thanks

Hi,

Regex Coach is not based on the C library PCRE.  It's based on
CL-PPCRE which is a Lisp library I wrote myself.  You can find a link
to it and its documentation on the website.

Cheers,
Edi.

I see, thanks. I checked that page but I don't see any mention of
the \K option. Am I to assume that its not supported in your library?
Is there a similar switch?

Thanks,
Mike

Right.  Actually, until now I had never heard of the \K switch (or I
forgot about it).  CL-PPCRE is largely modeled on Perl (at a
particular point in time) and when I wrote CL-PPCRE, Perl didn't have
\K.

>From a quick look at the PCRE docs I'd say that some of the \K
behavior can probably be emulated using look-behind assertions.

Ah-HA! Now it all falls into place. You were tired of Lisping when you typed, and so needed something to quickly find-and-replace those anomalous distortions.

The universe is starting to make more and more sense.
