In Inno Setup tool (Windows OS)
InstallDir: string;
I have a string InstallDir which contains C:\-=[]\.,';
I want to set a regular expression pattern as below
^([a-zA-Z]:)\\([0-9a-zA-Z_\\\s\.\-\(\)]*)$
Ex: It should be c:\< A to Z / a to z > or number or _ and so on (means a valid path).
I could not find any function in Inno Setup, which tells it supports regular expression for string operations.
Can any body help me out to resolve this?
No, Inno Setup does not support regular expressions.
You may be able to invoke PowerShell for that, but that's an overkill.
You do not need a regular expression for your check:
function IsPathValid(Path: string): Boolean;
var
I: Integer;
begin
Path := Uppercase(Path);
Result :=
(Length(Path) >= 3) and
(Path[1] >= 'A') and (Path[1] <= 'Z') and
(Path[2] = ':') and
(Path[3] = '\');
if Result then
begin
for I := 3 to Length(Path) do
begin
case Path[I] of
'0'..'9', 'A'..'Z', '\', ' ', '.', '-', '(', ')':
else
begin
Result := False;
Break;
end;
end;
end;
end;
end;
(The code requires Unicode version of Inno Setup, what you should use anyway and it is the only version as of current Inno Setup 6).
