pcregrep question

[bruce]

Hi.

I'm embarrassed to say I can't resolve this. So, my mind has gone blank!

I've got a test file, with the following lines. Basically, I want a
grep/regex to traverse the multiple lines to return the lines.

ll_=urllib.quote_plus(simplejson.dumps(b2))+"\n"
pathchildcount_filep.write(ll_)

I've tried a number of attempts.. I thought something similar to the
following should work. (but no luck)

pcregrep  -Mi ".+urllib.quote_plus(simplejson.dumps(b2))(.+\n).+path" foo.py

The test file actually has the "\n" chars as text but the regex/grep can
ignore it, to focus on getting the two lines..

In the case of the example, both lines start at the beginning of the line.

Thanks

(no laffing!!)

Had you thought about sed? Untested:

sed -n '/^ll_=urllib.quote_plus(simplejson.dumps/,/^pathchildcount_filep.write/p' foo.py

(One line, in case your mail read folds it.)

I've simplified the regexps, but I'm sure you get the idea.

Cheers,

oh.. my bad.. sorry..

here's what I developed to solve my issue in case others need it

pcregrep  -M 'urllib.quote_plus(simplejson.dumps(b2)).*\n.*path
*Parse_cloud_test.py

this allows for searching for content across multiple lines (across a \n
newline)
