Visual Studio Regex Find and Replace function

Question

I'm trying to find all var.AppendLine("..."); and replace them with Append("...\n");

Been fooling around with regex's but don't seem to get anywhere. Anyone has a suggestion on what regular expression to use here?

var can be a variable name and I need to select the ... for replace with Append("$1\n");

Well i googled a bit, but don't seem to have found anything that has results... Flying blind. — ferdyh

Sounds a bit dangerous... how confident are you there are no "); WITHIN the text anywhere in the code? — freefaller

I assume you actually don't want to get rid of var:

Search: <{[a-zA-Z0-9]+}.AppendLine$"{[^"]+}"$

Replace with: \1.Append("\2\\n")

Thanks Chris, almost there... I've used this now: (VS 2012): ([a-zA-Z0-9]+).AppendLine$"([^"]+)"$ however, it selects sb.AppendLine.. and then b.AppendLine.. again...

@Ferdy: Fixed, need to match on word start

Adding the < breaks the regex for me. Has something to do with the tabs / spaces infront of it?

@Ferdy: Works fine for me in VS2010

Using VS 2012, got it working, however... It adds \\n at the end of the Append. When i use \n it adds a new line. Any way of adding \n litterally?

I think you meand the regex in the "search& replace window of VS ? Then something like

<{[a-zA_Z]+\.}{AppendLine\("}{[^"]+}{"\)}

to replace with

\1Append("\3\\n")

(remove the \1 if you want to remove the "var." part, not clear in your question)

TIL that VS Replace uses curly braces, not brackets, for capture groups :-/

That looks like MSVS 2010 RE syntax, but the question is about MSVS 2012, which uses .NET RE syntax.
