I have implemented the following replacement patterns in a stand-alone function
It supports numbered groups, named groups, $$, and $&. My next step is $` $'
$+ and $_
Here is how its used in my code base (from my unit tests)
auto pattern = R"(\p{Sc}*\s?(\d+[.,]?\d*)\p{Sc}*)";
auto replacement = "$1";
auto input = R"($16.32 12.19 £16.29 €18.29 €18,29)";
auto result = NSABUtils::NStringUtils::regExReplace( input, pattern,
replacement );
auto pattern = R"(\p{Sc}*\s?(?<amount>\d+[.,]?\d*)\p{Sc}*)";
auto replacement = "${amount}";
auto input = R"($16.32 12.19 £16.29 €18.29 €18,29)";
auto result = NSABUtils::NStringUtils::regExReplace( input, pattern,
replacement );
auto pattern = R"(\p{Sc}*\s?(?<amount>\d+[.,]?\d*)\p{Sc}*)";
auto replacement = "$ $${amount}";
auto input = R"($16.32 12.19 £16.29 €18.29 €18,29)";
auto result = NSABUtils::NStringUtils::regExReplace( input, pattern,
replacement );
auto pattern = QString( R"(\b(\d+)(%1(\d+))?)" ).arg( cSeparator );
auto replacement = "$ " + QString( "$1$2" );
EXPECT_EQ( "$ 16.35", NSABUtils::NStringUtils::regExReplace( "16.35",
pattern, replacement ) );
I would prefer if it was something like
Result = regex.replace( replacePattern )
Here is the notes for C#'s regular expression replacement.

Yes, it can be done, but I think it should be built into QRegularExpression

Subject: Re: [Interest] QRegularExpression for replace
Maybe I'm dumb, but I'm still not sure what is being asked for.
If it's regular expression replacement with back-references in the replacement
string, I think that's possible with QString::replace like I showed.
