Question

I use C# basically. There I can do:

string trimmed = str.Trim('\t');

to trim tabulation from the string str and return the result to trimmed.

In delphi7 I found only Trim, that trims spaces.

How can I achieve the same functionality?

Answer 1

This is a kind of procedure sometimes easier to create than to find where it lives 🙂

function TrimChar(const Str: string; Ch: Char): string;
var
  S, E: integer;
begin
  S:=1;
  while (S <= Length(Str)) and (Str[S]=Ch) do Inc(S);
  E:=Length(Str);
  while (E >= 1) and (Str[E]=Ch) do Dec(E);
  SetString(Result, PChar(@Str[S]), E - S + 1);
end;
