Subject RE: replaceregex
Date Sat, 16 Jun 2007 13:59:28 GMT
I finally got it to work using <filetokenizer>. It converted everything in
such a way that I could recognize "\n" with the regex "[\n\r]+";
consequently, now I can perform multiline search/replaces. I tried the
flags="s", before posting to this mailing list, but I couldn't get it work
either. I don't think ant regex likes the newline character that editors
produce. Although I spent of time figuring it out, it is working fine now.
The plus side is that I read a lot of help pages on regular expressions
hoping to find the answer, which I didn't, but I learned a lot about regular
expressions and "ant" itself! The negative side is that I decided that what
I was doing was unnecessary because it was complicating the build process so
I dropped the whole idea; embedding examples inside of resource files would
only confuse people. I simply created a "Readme.txt" file to explain how to
setup resources instead. I allow comments because resource files can be
documented.

Well, i'm glad that tribulation is over!

Thanks,

You normally need the "s" flag to get the
pattern to match "\n": from the manual:
"""
s : Singleline. Treat the string as a single line of input, using "."
to match any character, including a newline, which normally, it would
not match.
"""
