• Website get a Diem website built by the Diem team
• Support get plugins built specifically for your needs
• Training become more efficient working with symfony and Diem
• Web-design get a nice looking theme for your Diem website

I'm personally involved in this expert team, and eager to work on your project. Except the web-design part, of course. Believe me, it's a good thing.

At the same time development of 5.1 continues, powered by the community, and 5.2 is on its way. We're also experimenting with Symfony2, to prepare the next generation of CMS.

Stay tuned, and get in touch with Diem experts now!

It works by changing the "robots" meta value. This is usefull for keeping control of your SEO, especially when your website content is not fully ready for indexation.

However, until today, the "Site indexable" setting was set to false by default. This means that all your pages had robots meta "noindex,nofollow". In light of this you are strongly encouraged to check this setting and change it to true in order to make your website appear on search engines like Google.

Be aware that this setting is culture dependent. If your website is multilingual, you need to change the setting value for each culture.

Next versions of Diem (5.0.6, 5.1.2, 5.2) will have this setting set to true by default.

I'm pleased to anounce the immediate availability of Diem 5.1 stable!

This new version brings popular features like mailing, enhanced symfony filters, "Forgot password" widget, unlimited Areas per page and layout... and many others new features.
It is NOT compatible with Diem 5.0, but upgrade is easy.
I'd like to thank the community for the huge work completed on this release. 11 authors contributed to Diem 5.1, with 374 commits.

Diem documentation is quite complete:
22 Reference Book pages
+7 Diem Ipsum pages
+7 Howto pages
*2 versions (5.0 and 5.1)
= 72 pages

Untill today, only diem-project.org webmasters were able to write and fix Diem documentation. That was a hard time.

So I took some time to move all documentation to GitHub: Diem Documentation GitHub repo. Now you can create documentation issues, and even better, fork and improve it!

Git branches are used to separate 5.0 and 5.1 documentation: 5.0, 5.1.

The best thing is that diem-project.org pages are synchronized with the documentation repository. Each time we push to GitHub, the website is automatically updated, thanks to a post-receive hook.

Synchronize a Git repo with a database

In case you need, as I did, to update a database each time a Git repository receives data, this section may help you.

Install a local repo on the production server

As diem-project.org is itself a Git repo, I added the documentation as a submodule:

git submodule add git://github.com/diem-project/diem-docs.git data/diem-docs  

Configure the GitHub repo

Add a post-receive hook url to the GitHub repo. The url must execute a symfony action on the website.

The symfony action

So this action gets called each time Diem GitHub repo receives data.
We need to fetch the files using Git, then read them to upgrade the database.

// handle GitHub post-receive hook  
  public function executeUpdateFromGit(dmWebRequest $request)  
  {  
    $this->forward404Unless($request->isMethod('post'));  
 
    $repoDir = sfConfig::get('sf_root_dir').'/data/diem-docs';  
 
    // include phpGitRepo  
    require_once(sfConfig::get('sf_root_dir').'/lib/vendor/php-git-repo/lib/phpGitRepo.php');  
 
    // create a git repo instance  
    $repo = new phpGitRepo($repoDir);  
 
    // run the synchronizer passing it the repo instance  
    $synchronizer = new gitDocumentationSynchronizer($repo);  
    $synchronizer->execute();  
 
    return $this->renderText('done');  
  }  

See the action code on diem-project.org GitHub repo

To get new files from the GitHub repo I used php-git-repo, a lightweight PHP abstraction layer to Git.
I create a phpGitRepo instance and pass it to my database-specific synchronizer.

The synchronizer

For each Diem branch (currently 5.0 and 5.1), the synchronizer will checkout the appropriate Git branch and update it from the server using php-git-repo.
Then it compares files to the database content, and updates the database if needed.

class gitDocumentationSynchronizer extends dmConfigurable
{  
  protected $repo;  
 
  public function __construct(phpGitRepo $repo)  
  {  
    $this->repo = $repo;  
  }  
 
  public function execute()  
  {  
    $this->repo->git('fetch origin');  
 
    foreach($this->getBranches() as $branch)  
    {  
      $this->checkoutBranch($branch);  
 
      $this->updateBranch($branch);  
 
      $this->updateDatabase($branch);  
    }  
  }  

See the synchronizer code on diem-project.org GitHub repo

If you find a typo on Diem documentation, or wanna see something documented better, feel free to create an issue. Or even better, fork the repository and pull your contribution request.

Happy Dieming and stay tuned, Diem 5.1 is coming along very, very nicely!

The world will remember March 11 2010 as the day Diem 5.0 stable was released! Champagne!

Diem development has been frenetic and many Alpha, Beta and Release Candidate versions have been released. Finally, the time for the long-awaited stable version has arrived!
The 5.0 branch will be supported for a long time and is suited for production websites.

By the way, Diem 5.0 is already being used by many websites. It also has a vibrant community, aided by the excellent symfony developers from all around the world. When I write these lines 16 Diem plugins are available. The documentation is solid, with a reference book, a complete tutorial and some usefull howtos.

I'd like to thank the amazing community that made this possible. Thank you guys!

The front editing tools have been enhanced according to community feedback, and more resizing/cropping options are available in the media widget dialog.
Each authenticated user that accesses to the admin app now has a dedicated page to modify his/hers email and password.

French & Italian translations have also been updated.

Bugs fixed

A possible issue with Google Analytics, some minor problems with JavaScript and an error when using onDelete: RESTRICT on a Media relation have been fixed.

Documentation

A new documentation page is available: Learn how to use Diem Doctrine behaviors. The Security and users doc has been completed to explain how to allow visitors to modify their information.

Diem 5 Release candidate is here! This is the first Git release, full of great stuff, so go get it now!

• Download
• Release notes
• Fork it on Github

This release is the result of an incredible amount of work from the community. It brings all requested features, and even more!

Admin goodies

Media Library

The media management interface has been refactored and completed to give you full control of files and folders. Furthermore, uploading an existing file no more replaces the existing one, but saves a new one with a unique suffix.
Try it on the demo site! (username: admin, password: admin)

Code editor

The admin interface now features an ajax editor. It allows you to browse the entire project, open, modify and save files.
Try it on the demo site! (username: admin, password: admin)

Page management

Now you can sort and move pages around easily with a nice JavaScript tree.
Try it on the demo site! (username: admin, password: admin)

Manual SEO

Admin now features a great way to review and modify all pages metas and url's.
Try it on the demo site! (username: admin, password: admin)

Usability

As content writers will be spending hours working with your site's admin, we revised it:
Usability has been enhanced a lot with icons for translatable and required fields, helpful tooltips, JavaScript search for big checkbox lists, better record and diagram generation, ajax pagination of big related record lists, and more...

Front goodies

Edit records

In Diem 5.0.0 BETA5, you could modify everything directly on the front, except... the records (Product, Article, ...).
Things have changed! Users who have the "record_edit_front" permission now see a big edit icon on these pages. It opens a box and lets them modify a record using the admin interface, and the page content are refreshed with Ajax upon saving. Damn easy and secure, it offers the best interaction with your site for your customers.
Try it on the demo site! (username: admin, password: admin)

Tool Bar enhancements

All adding features (including adding pages) have been moved to the "Add" menu. This menu features a JavaScript search to help you find Widgets faster.
Try it on the demo site! (username: admin, password: admin)

Developer goodies

Upgrades

Diem always provides cutting edge software. Symfony has been upgraded to 1.4.2, jQuery version is 1.4.2 as well (hey, it's not even released on jQuery site when I write this post!) and the jQuery UI version bundled is 1.8RC2.

Social websites

It's now very easy to allow your visitors to signin and/or register themselves from the front. Learn how to use the new user/signin and user/register widgets.

Plugin conventions

To allow plugins to provide both admin and front modules, a new convention has been introduced. See the upgrade for 5.0.0-RC1 documentation.

Better automatic cache invalidation

The cache is now cleared selectively when you manipulate records or media or when you modify files from the front or admin code editor.

New plugins

Plugins continue to come quickly. You should try dmTagPlugin, that allows to add tags to your records with a nice JavaScript autocompleter, and create one page per tag on the front. Also, dmGithubPlugin allows you to interface your site with GitHub repository. It's as easy as a Drag&Drop!

Bugfixes and tests

As always, I'd like to thank the community for testing Diem in depth. Bugs are fixed quickly and Diem has now more than 3800 tests to prevent any regression.
Please continue to report any issues you find, and suggest improvements, with the very user friendly GitHub issues interface!

Oh, and two new translations have been added: Slovene (thanks Mitja Debeljak) and Romanian (thanks Manea Liviu).

Enjoy!

As explained some time ago in symfony blog, Git is a a distributed revision control system that eases contribution. It's already used by jQuery and Symfony 2.

Core

Diem official repository is now http://github.com/diem-project/diem.
To fetch it the first time, clone it, then update its submodules:

git clone git://github.com/diem-project/diem.git    
cd diem    
git submodule init    
git submodule update    

Then, later, to update it:

cd diem  
git pull  
git submodule update  

Be aware that the Diem SVN repository is no more updated.

Plugins

All plugins have been moved to GitHub. You can access plugins repos on the plugin pages.

Tickets

We now use the excellent and very user friendly GitHub issues system. It's way more easy and fast to report bugs and request features than with the good old symfony trac.

Contribute

Git makes contributing damn easy. Just hack your local Diem repo, then send a pull request on Diem GitHub page.

Having Diem on GitHub is a very good thing.
Come on, we're waiting for your issues and contributions!

Menus

The dmMenu class now allows you to create dynamic recursive menus very easily, thanks to dmMenu->addRecursiveChildren($depth) method.
Additionally, Diem now provides a new Menu Widget. It allows you to create and manage menus directly on the front, without any technical knowledge. Just drag, drop, and click.

Admin enhancements

Real time resource locks

Diem is designed to be used in a team. If many writers work on the same content at the same time, some work could be lost. To avoid that, resource locks have been implemented, using Ajax ping requests. Users modifying a resource are displayed in real time, so you can wait they leave to start modifying it yourself.

Markdown editors

The markdown editor now provides a Full Screen mode, that resizes the textarea and the preview zone to the window height in one click. Also the preview scroller is now synchronized with the textarea scroller.

Media library

Entirely refactored and 100% tested, the new media library now allows you to move and rename files and folders. The media synchronizer has also been rewritten. When you add files and folders in your upload dir with your OS, then open the admin media library, everything is automatically synchronized.

Front enhancements

Copy and paste widgets

You can now cut, copy and paste your widgets from one page to another. Open the widget dialog, click on Cut or Paste. The widget appears in the "Add" menu, on the CLIPBOARD section. You can now drag&drop it normally onto the page.

Plugins

New plugins are available:

• dmGoogleMapPlugin displays google maps on your site without writing a line of code
• dmContactPlugin allows visitors to send you contact requests
• dmCommentPlugin adds commentable capabilities to any of your models.

Other plugins have been improved and are 100% backwards compatible.

And more

Updated libraries

• jQuery 1.4.1
• jQuery UI 1.8rc1
• Zend Framework 1.10

Performance

Front widget cache is now faster, more assets are loaded asynchronously and the editor javascript code has been profiled and improved.

Compatibility

• stylesheets have been optimized for WebKit-based browsers like Google Chrome
• you can now decide to include a JavaScript library in the head section to make some symfony plugins work
• template helpers do not use the "£" symbol anymore

Stability

Many bugs have been diagnosed and fixed. The continuous integration server now runs more than 3300 tests on each commit, to ensure the stability of the trunk.

• Download Diem 5.0.0-BETA5
• See version notes and upgrade instructions

We're really happy to bring you this fourth BETA release.
It makes Diem faster and more stable than ever.

Now translated in seven languages

This week, two complete translations were added by the community!
Big thanks go out to Vasiliy Ivanov for the Russian and to Bojan Jankuloski for the Macedonian translation.

Faster front editing

A new asynchronous asset loading system has been developed.
Front editing uses lots of cool JavaScript to make page editing fast and fun. Now they get loaded only when necessary, making page loading faster than ever.
Page, widget, zone and code editor dialogs already use this new feature.
Also, jQuery UI was upgraded to 1.8b1, which proves to be very stable.

Google Chrome support

Diem editing features can now be used with Firefox or Google Chrome.
Next step: make it available for Safari.

Plugins

The dmWidgetTwitterPlugin has been released. It allows to display tweets from a user or from a search query in your site. All you have to do is drag&drop, as usual.

The dmWidgetFeedReaderPlugin has been released. It displays feed items from a url, and works the same way.

These plugins are well documented and fully extensible.

Additionally, all widget based plugins have been updated to use the new asynchronous asset loading system, and you should consider to upgrade them.

Internal changes

Log services

On the admin homepage you can see logs updated in real-time.
They show the users browsing your site, and report notable events like page creation.
Behind them are the request_log and event_log services. For this release they were rewritten to be faster and more stable. Also, the log format has been changed to make log files lighter.

Transliteration

Transliteration is the practice of converting a text from one writing system into another in a systematic way.
Now Diem transliteration is culture aware and can handle different alphabets.

Bug fixes

Thanks to the rich community feedback, lots of bugs has been fixed.

Code cleaning

An intense internal refactoring and cleaning was performed to keep the Diem codebase as light and clean as possible. Some unused classes and methods were removed. The law of demeter was applied whenever possible in Diem's internal services.

As this release is compatible with Diem 5.0 BETA3, upgrading is highly recommended to get the best Diem has to offer!

Let's try it

front http://demo.diem-project.org/

admin http://demo.diem-project.org/admin

Username: admin
Password: admin

What to try

Admin

Content

Open the content menu and browse the site contents.
Try the Diem admin interface and verify that it will fit your customers needs.
Have a look at the versioning interface, the sorting interface, batch actions, search engine, foreign column sorting and markdown editors.

Tools

Open the tool menu and try some features Diem packages natively.
Have a look at the customizable configuration panel, the nice generated charts and the log view.
Also, give the media library a try.

SEO

Open the Seo menu and run the sitemap generator and the automatic page meta builder.

System

Have a look at the generated database and dependecy injection diagrams, check the server configuration and browse the error log.
Unfortunatly, for obvious security reasons, you won't have access to the AJAX terminal nor the code editor ;)

Front

Open the left PAGES panel and navigate with the page tree, or the right MEDIA panel and browse the media library.

Try the buttons on the lower toolbar. You are allowed to create pages, and modify urls and metas.

By clicking on the magnifier, you toggle ON the page edition. It allows you to drag&drop widgets around the page, and transform it to a joyfull mess.

Click the Add button and drag&drop nice things all around.

See the code

As you probably noticed, the demo is a full copy of this website.
Play with it is fun, but do you wanna see what's inside?

This is possible as this website is open source. You can download it, and get the exact same demo running on your computer.

Download and install diem-project.

What's new?

Javascript speedup

jQuery 1.4 is just released and Diem 5.0 BETA3 already packages it. It brings amazing performance improvements to admin and front edition interfaces.
Diem now uses jQuery UI 1.8 ALPHA2 instead of 1.7, bringing user interface to its best.

More tests, less bugs

The test frenzy is not over: 900 unit and functional tests were added since BETA2.
Many bugs were detected and fixed, and each of them got some regression tests.
Hudson works day and night to ensure each SVN commit is safe.

Improved services

Thanks to the service architecture and dependency injection container, Diem components are decoupled and can evolve separately. For BETA3, the following services got some love:

• xml_sitemap_generator now generate one file per culture, plus an index as recommended by http://sitemaps.org/
• front_pager_view has been refactored and propose nice options like "ajax"... see the widget list pager documentation
• menu has been improved and is declined in sitemap_menu
• browser_detection has been extracted from browser and is more accurate and even faster than before

Documentation

Documentation has been improved with List widgets, Exclude files from JS minification and Customize the breadcrumb.

Plugins

The long-waited dmCkEditorPlugin is available.
dmWidgetGalleryPlugin and dmFlowPlayerPlugin have been updated to benefits from the enhancements brought to widget Ajax edition. If you use them, please grab the latest version from SVN.

Happy Dieming, and please continue to ask questions and report bugs!

Diem is already heavily tested, and many tests are added day after day. Now with more than 2200 tests, it became tedious to run them manually.

So I searched for a continuous integration server for Diem 5.0.

Sismo, the sensiolabs CI, is not available yet.

There is an excellent blog post about using Hudson to test symfony applications. I tried it, and saw it was good.

Hudson is now running on http://ci.diem-project.org/. Each day, it builds a new project from latest Diem 5.0 SVN repository, and runs all unit and functional tests.

The results are available online, and we can also follow the build results on twitter and subscribe to the builds RSS feed.
Informations about Diem 5.0 health are also displayed on the Community & Development page.

Say hello to Hudson, our new BETA tester!

Here is the second BETA release for Diem 5.0.

Tests

The main words here are tests and stability. Diem is now controlled by a continuous integration server which run all 1800 tests each day. Its little name is Hudson, I'll present him to you soon.
Run these tests from your project:

php ../diem/prove  

Menu

As requested by the community, the excellent sfSympalMenu was ported to Diem.
Check out what the new Diem Menu service can do for you, and build a complete sitemap menu in two lines of code.

Improvements and bug fixes

I'd like to thank the community. You reported (and sometimes even fixed) tons of bugs, making this release more stable than ever.
The Diem plugin system was improved, making even easier to you to create your Diem plugins.
As planed, the loremizer service has been refactored and packaged as services.
And much more: Windows support improved, admin interface enhancements, ORM performance boost, better support of APC...

Keep up the good work and together we are going to bring to professional symfony users a powerfull and stable open source CMS!

Download Diem 5.0 BETA2
View the complete changelog

I spent some time working on something unusual, useless and fun. I developed the very first "Online Chess Game Without Registration Or Proprietary Technology" in this world!

Here is the Diem Chess demo!

It features an ajax interface which indicates valid moves and a serverside artificial intelligence.

You can choose to play alone or invite a friend by just giving him or her a url.

And the best of it is that Diem Chess is available as a Diem plugin!

Feel free to study it, use it on your site, tweak it, improve it.

Who said CMSs just do websites?

What's this about, anyway?

You are probably wondering what delicious new things made it into this release so I will give you the birds-eye view. Firstly, this release is about implementing features that the community requested and also about fixing bugs, bugs that were also reported by the community!

Features, features, features

Secondly, this release marks a point in Diem's development, so as long as the community requests features that are worth the effort of implementing for the final version or reports bugs, we will keep iterating in new BETA releases. Keep these feature requests and bug reports coming! You can reach us through the usual channels (Google group, symfony trac, Google Wave, IRC).

What's in it for me?

Usability and accessibility

Also important to us were usability and accessibility. We added the new Diem Core plugin dmAlternativeHelperPlugin which provides Diem template helpers for people without the pound sign on their keyboards. In the Markdown editor you can now select some text and add a link to it by dragging and dropping a page from the pages panel onto it, whereas previously this drag and drop operation resulted in the link being added to the end of the text. This is a big improvement and a real time-saver (we do know from personal experience)! Also of note here is that the Markdown syntax was extended to allow for the addition of css classes and ids to links and media. Of course, in case of images, image dimensions can also be added. You can find the documentation for this right here.
We also took some time to make this version the first to be able to run on Windows©-based servers, thanks to the community providing insight, bug reports, and patches!

Database goodies

The database part also got some love, with Diem now running smoothly on PostgreSQL and SQLite. Furthermore, database versioning is now fully supported with a generated admin interface to manage record revisions (see record versioning documentation) but this needs to be enabled explicitly and does not work on tables that use internationalization.

Simplified installation

That's a nice one as it really makes the installation smoother, which means you can start playing with it even faster! Here's the new way:

  mkdir myproject  
  cd myproject  
  php ../diem/install  

See? Smooth.

And a few other...

A few other things also made it into this release. A complete Italian translation has been added thanks to Marco Barberis and the French, Spanish and German ones were updated by their respective authors. The media system is now more flexible to allow for plugins providing media players. Lastly, the unit test suite saw a significant boost in coverage due to the community's work! We now have over 1000 unit tests and will continue towards a full coverage but that will take more time, so keep the tests coming!

Start playing with it now!

To start playing with it, you can either take a look at the installation page or you can do a Subversion checkout:

  svn co http://svn.symfony-project.com/plugins/diemPlugin/tags/RELEASE_5_0_0_BETA1 diem  

As always, report any bugs you find!

The Diem Core team thanks all people that made this release possible and as awesome as it turned out, thank you community!
