in previous versions if we replace something in regex mode with a sentence like (foo) parentheses is also included in result, but with the version 6, now parentheses in replace with string must be escaped with \ character. For repeat this try:
-open a new document
-write 1 in it
-replace 1 with (foo) in regex mode
-now document only includes foo (in old versions documents contains (foo) )
Yes, it's a side effect of the new regular expression support. You answered your own question though - you can escape the parentheses with \.
What it means, is that you can do advanced replaces:
With the text
hello test 153
hello test word
something test 63822
something test wibble
?1 says "if grouped expression 1 was matched, then replace with the following, otherwise replace with what comes after the ':'.
For a full list of everything you can do, see http://www.boost.org/doc/libs/1_48_0/libs/regex/doc/html/boost_regex/format/boost_format_syntax.html
So yes, you need to escape your parentheses for the replacement string, but you get a whole load of functionality in return.
Thank you Dave,
i am not aware of this new functionalities. Generally i do simple replacements with regex and i will miss unescaped replace with string, but new features are also cool.
I can confirm that this bug still exists in 6.1.4
If you read the rest of this thread, you'll see it isn't a bug.
