Delphi and C++ Builder VCL community is so big that you can find a various set of libraries, functions and non-visual classes which can be instantly reused by developers.
One of the popular libraries is the JEDI Code Library (JCL) – The library is built upon code donated from the JEDI community. It is fully documented and fully tested. The library is grouped into several categories such as Strings, Files, Security, Math, IO, and many more.
JEDI Code Library is available on the GetIt package manager. And it is easy to download and install to your RAD Studio.

Does it fully support Unicode strings..?
It supports Unicode, but JEDI is huge, so to say it “fully supports Unicode” may be a difficult claim to make.
Hi dear,
I installed JCL (2022.02) and JVCL (2022.02) through the GetIt Package manager.
Restarted the RAD as Asked.
But if I try to use one of the jcl library like in the example in the use section, like JclFileUtils, JclStrings, JclSysUtils, … I received this kind of error [dcc32 Fatal Error] Unit1.pas(7): F2613 Unit ‘JclFileUtils’ not found. Am I doing something wrong ?
unit Unit1;
interface
uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, JclFileUtils, JclStrings, JclSysUtils;
type
TForm1 = class(TForm)
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
end.
Thanks for helping.
Cédric
It looks like your library path doesn’t include the JCL DCU folder.
As of June 2025 JCL and JVCL can’t be installed through GetIt Package manager. Even the Installation & Uninstallation process doesn’t work even on Trial Version. Errors are just over looked and if I deleted the Package Folder it would still show that the Package is Installed.
Hi there. Thanks for letting us know. I’ll get in touch with the Jedi maintainers and see if we can collectively sort out the problem.
hello Ian!
any updates on the matter?
Delphi 13 getit package manager doesn’t even show jcl/jvcl
I have been in touch with the Jedi team, and they do support RAD Studio 13 Florence but currently that is via their GitHub installation process. We’re working to make Jedi JCL and JVCL available via GetIt but it’s not quite ready yet – there are some stumbling blocks to overcome first.
