Advanced Regexp Question
Hello,
I am able to do some very simple regexp replacement with the replaceregexp
ant task but now need to do something a little more advanced.
Say I have a string in a file like this:
require(["a","foo/b","foo/c"], function(){...})
What I want to do is replace all the "foo" with "bar" so the final product
looks like this:
require(["a","bar/b","bar/c"], function(){...})
With replaceregexp the best I've been able to get was below using regexp
like "require\(\s*\[(.*)foo/([^\]]*)\]"
require(["a","foo/b","bar/c"], function(){...})
(I can't just do a global replace on "foo" because I only want to do the
replacement in this "require" context.)
Any ideas?
Thanks for any advice,
Greg

I could be wrong, but my guess is he wants this first pass (I suppose
because that's what I'd want)...
The only problem with twice is...it doesn't address what happens if there
is a third, fourth and fifth (and so on) references...

Run your regexp over the file twice? Second pass will catch the foo that
was left over the first time.

Greg,
I've been looking at this for about an hour or so...
I'm stumped too ;)
