Code-golfing is incredibly fun to do, trying to solve the given problem is one thing but the real challenge is getting your code as short as possible.
Some languages are perfect for golfing because of their short commands, sadly Delphi isn't one of them.
I'm looking for tips that are useful for golfing in Delphi.
Tips like "Use 1 letter variables" don't really count in my opinion since that is pretty obvious.
Tips I learned working with Delphi or found in other peoples answers so far are:
- Semicolon isn't always required (Example 1)
int16as datatype rather than integer (saves 3 or 2 characters)
- Combine string manipulations(Example 2)
Procedure Example1(i:int16); var x:int16; begin for x:=0to 99do if i=1then inc(i)//Semicolon not allowed because of "else" else i:=i+3//No semicolon required end;//Semicolon required
function WrongExample2(myString:string):string; const f:string='The result of your manipulation is: %s'; begin myString:= StringReplace(s,'x', '_', [RfReplaceAll]); Result := Format(f,[myString]) end; function CorrectExample2(myString:string):string; const f:string='The result of your manipulation is: %s'; begin Result := Format(f,[StringReplace(s,'x', '_', [RfReplaceAll])]) end;
i:=i+3is shorter then
constcan automatically resolve types, in your case
:stringis not required. \$\endgroup\$
