Use ReNamer only for a part of the filename

Dear experts, I have a question.
I have filenames like
"Left PART-Right PART of THE first fileNAME 001"
I want to leave the left part (before the hyphen) unchanged.
Is there a possibility to set the rules in ReNamer that it only changes the right part, after the hyphen?
I want to remove the spaces and "captitalize and preserve" the right part of the filenames (after the hyphen).
=>
"Left PART-RightPARTOfTHEFirstFileNAME001"

Best regards
Torsten

Re: Use ReNamer only for a part of the filename

Currently, there is no easy way to apply rules only to a part of the filename.

However, your task can be accomplished with the Pascal Script rule, using a script below:

var
  HyphenPos: Integer;
  BaseName, PartLeft, PartRight: WideString;
begin
  HyphenPos := WidePos('-', FileName);
  if HyphenPos > 0 then
  begin
    BaseName := WideStripExtension(FileName);
    PartLeft := WideCopy(BaseName, 1, HyphenPos);
    PartRight := WideCopy(BaseName, HyphenPos+1, WideLength(BaseName));
    PartRight := ReplaceRegEx(PartRight, '\b(\w)', '\u$1', False, True);
    PartRight := WideReplaceStr(PartRight, ' ', '');
    FileName := PartLeft + PartRight + WideExtractFileExt(FileName);
  end;
end.

Thank you very much for the Pascal Script. It's exactly doing what I want

By the way, you can learn more about the scripting features at our Pascal Script wiki article.

Re: Use ReNamer only for a part of the filename

Thank you for this hint. I am not really able to write scripts in Pascal but I understand the script you have created except the following line: "PartRight := ReplaceRegEx(PartRight, '\b(\w)', '\u$1', False, True);"
Could you explain to me what "'\b(\w)', '\u$1', False, True" is doing?

Re: Use ReNamer only for a part of the filename

ReplaceRegEx() >>> https://www.den4b.com/wiki/ReNamer:Pasc … xpressions

ReplaceRegEx(Input, Find     , Replace, CaseSensitive, UseSubstitution);
ReplaceRegEx(Input, '\b(\w)', '\u$1'   , CaseSensitive, UseSubstitution);

\b + \w + \u >>> https://www.den4b.com/wiki/ReNamer:Regular_Expressions
For "(...) and $1" >>> see there at "Substitution of text using backreference"
Means: find one sign of "an alphanumeric character" at a "word boundary" and capture the match in (...) parentheses
for reuse later by $1, which has the option \u to "Convert all characters to upper case".
So match the first sign of an word and change the case to upper, if need or not.
