MMX for Delphi 10.3 Rio

After apparently no critical show-stoppers were found during the beta phase, the new release of MMX version 14 is now officially available.  MMX Setup

A list of changes can be found in the Change Log.

Besides the support for Delphi 10.3 Rio perhaps the biggest change is dropping support for oder Delphi versions. Since version 14 MMX will only support Delphi 10 Seattle and higher. For older versions you can still use version 13, which can be found at the MMX download page when clicking on Previous versions.

Dropping support for those older versions was inevitable to assure further development of MMX. It turned out that making things work for those Delphi versions would burn too much valuable time, which I can now dedicate to new features and the extension of existing ones.

MMX gets a new setup

While we are at about 5300 downloads today (hooray!), some users complained about the installation process requiring admin rights and lacking proper support for multi-user environments. It turned out to be quite challenging to get MMX working properly when the actual Delphi user doesn’t belong to the admin group. To the rescue Jeroen W. Pluimers wrote an article about that, also giving a solution to fix such a broken installation.

As I am responsible for MMX now, I also feel responsible for the problems users have because of this somewhat suboptimal installation process. The setup of a product can be seen like the front door of a building. If it is hard to enter, that will produce a negative feeling, sometimes just unconscious. People may even be discouraged to enter at all.

Looking through the reports I came up with the following goals that a new setup should target.

  • Admin rights should not be a requirement to install. Also a normal user should be able to install MMX into his Delphi version.
  • It should be possible to have an administrative installation, where normal users will only have to register MMX into their Delphi. At best, the last step happens silently.

Both installation scenarios have different consequences. The per user installation, will have a separate copy of MMX for each user. This may lead to different users working with different MMX versions. As an advantage, each user can make an update on his own. The disadvantage is, that each user has to make an update on his own.

On the other hand, the admin installation guarantees all users will use the same MMX version. Updates are effective for all users at once, but have to be done by an admin.

The new setup shows this behavior:

  • When the current user has administrator rights the setup will install into <ProgramFiles> as before. If this user also happens to have a valid Delphi installation, MMX will be registered there directly. This mimics the previous behavior.
  • If a normal user executes the setup and such an administrative installation is found, the setup will only register MMX in the current users Delphi. With the exception of Delphi 7 this step is optional. All other versions do an auto-registration of MMX on the next Delphi start.
  • If a normal user executes the setup and no administrative installation is found, the setup will install in the users <AppData> folder.

In other words: When you are an admin you get an administrative installation. Each normal user has just to start Delphi then to get MMX working (except for Delphi 7). If you there is no admin available or wanted, the current user will get a personal MMX installation.

Have a look at the welcome screen when starting the setup. It will tell you what is going to happen.

BTW, the FAQ about verifying an installation still has to be updated to address these changes.


A New Home for ModelMaker Code Explorer™

I am very pleased to announce that as of today I am going to take over the award winning ModelMaker Code Explorer™ from ModeMaker Tools BV.

For over two decades ModelMaker Code Explorer™ is still an indispensable add-on to the Delphi IDE for numerous developers. Speaking for myself, a Delphi installation is simply incomplete without MMX. The benefit in using it always outweighed the price of this tool in magnitudes.

With ModelMaker Tools BV concentrating on its Mind Mapping tool SimpleMind, further development and distribution of MMX is now completely in my hands. To emphasize the movement away from ModelMaker Tools BV there will be a slight change in the name: ModelMaker Code Explorer™ will become MMX Code Explorer from now on, still shortened as MMX.

As a first and probably widely welcomed benefit MMX will be available for free with immediate effect. This allows even all hobbyist developers with a tight budget to make use of this tool. MMX will nevertheless stay closed source, though.

The first free release 13.0 is more or less the same as the current commercial release 12.3 in regard to functionality with all the licensing removed and (hopefully) all references to ModelMaker Tools BV changed to new targets.

Alas, the Delphi 5 and 6 versions didn’t make it into this transition, as they would have required too much special treatment. The current release thus supports Delphi 7, Delphi 2007 – 2010, Delphi XE – XE8, Delphi 10 Seattle, Delphi 10.1 Berlin and Delphi 10.2 Tokyo.

My plans for the coming releases are mostly:

  • cleaning up the code base (f.i. remove all C# related code)
  • restructuring the code while removing dependencies where possible
    (we all have our own ideas when it comes to architecture, don’t we?)
  • updating the documentation and examples (videos)
  • supporting new Delphi releases (goal is from day one on if not even beta)
  • better support of newer language features
  • implementing some ideas I collected over the last years

I am not going to conceal that this will most likely lead to drop support for older Delphi versions in favor of making maintenance easier. The latest MMX supporting those retired versions will nevertheless be available for download even after that.

Finally I want to say a big THANK YOU to Gerrit Beuze from ModelMaker Tools BV for his generosity and invaluable support in the past and during this transition.

Will MMX live long and prosper!
