Announcing Sapphire 9.1 and 8.3 Releases

Sapphire 9.1 and 8.3 releases are now available. These releases introduce TextSelectionService that allows the framework users to observe and manipulate the selection in a text property editor. Additionally, a number of fixes have been made to the localization system. Sapphire 8.3 is intended for adopters who are not yet able to require Java 8.

Announcing Sapphire 9.0.5 and 8.2.5 Releases

Sapphire 9.0.5 and 8.2.5 releases are now available. Both include a fix for the validation messages appearing out of order in some cases and a fix for the diagram editor context menu not displaying if the editor has been scrolled. Sapphire 8.2.5 is intended for adopters who are not yet able to require Java 8. Sapphire 9.0.5 will be part of the upcoming Neon release of Eclipse.

Announcing Sapphire 9.0.1 Release

On behalf of all who contributed, I am very proud to announce the availability of the Sapphire 9.0.1 release. This release includes a number of fixes in the areas of installation experience, performance and usability. It includes all of the fixes from the 8.2.1 release and is part of the Mars.1 release.

Announcing Sapphire 8.2.1 Release

On behalf of all who contributed, I am very proud to announce the availability of the Sapphire 8.2.1 release. This release includes a number of fixes in the areas of installation experience, performance and usability. It is intended for adopters who are not yet able to require Java 8.

Announcing Sapphire 9 Release

On behalf of all who contributed, I am very proud to announce the availability of the Sapphire 9 release. This release includes various API improvements, including integration with Java 7 and 8 language features (AutoCloseable and repeatable annotations). Additionally, reference properties now support transparent reference setting, meaning the target of the reference can be assigned to the property, but the model will still store just the id. This release is part of Mars.

Announcing Sapphire 8.2 Release

On behalf of all who contributed, I am very proud to announce the availability of the Sapphire 8.2 release. This release includes a new length constraint for value properties, text field capacity feedback, ability to expand outline nodes with a double-click and various bug fixes.

Announcing Sapphire 8.1.2 Release

On behalf of all who contributed, I am very proud to announce the availability of the Sapphire 8.1.2 release. This release includes a number of fixes, mostly in the area of accessibility.

Announcing Sapphire 8.1.1 Release

On behalf of all who contributed, I am very proud to announce the availability of the Sapphire 8.1.1 release. This releases includes a fix for an issue preventing the scale property editor presentation from being used along with a fix for a NullPointerException that occurs under certain circumstances when creating Java types from an action in a table cell editor.

Raising Sapphire minimum Java version

I am considering raising Sapphire's minimum supported Java version for the release 9 that will be contributed to Mars in the Summer of 2015.

The current minimum supported Java version is 6, last raised for the 0.7 release.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=409330

Java 6 (2006)

Dropping support for Java 6 would allow us to integrate Sapphire models with the try-with-resources feature by making Sapphire Element extend AutoCloseable.

try( Example element = Example.TYPE.instantiate() )
{
    ...
}

vs currently

final Example element = Example.TYPE.instantiate();

try
{
    ...
}
finally
{
    try
    {
        element.dispose();
    }
    catch( final Exception e ) {}
}

Java 7 (2011)

Dropping support for Java 7 would allow us to take advantage of multiple annotations per site improvement in Java 8 and allow us to remove the grouping annotations (@Service and @Services, @Validation and @Validations, etc.).

@Validation( rule = "${ Max >= Min }", message = "Must not be smaller than min" )
@Validation( rule = "${ Max <= 100 }", message = "Must be less than or equal to 100" )
    
ValueProperty PROP_MAX = new ValueProperty( TYPE, "Max" );

vs currently

@Validations
(
    {
        @Validation( rule = "${ Max >= Min }", message = "Must not be smaller than min" ),
        @Validation( rule = "${ Max <= 100 }", message = "Must be less than or equal to 100" )
    }
)
    
ValueProperty PROP_MAX = new ValueProperty( TYPE, "Max" );

Please respond to this post with your thoughts on what minimum Java version support you anticipate needing for Sapphire 9 in Summer of 2015.

Resolution: Based on the feedback received, the minimum Java version for Sapphire 9 and beyond has been changed to Java 8. As a consequence of this change, support for Indigo, Juno and Kepler was dropped (Eclipse added Java 8 support in Luna). Sapphire 8.x will continue to support Java 6 and all Eclipse releases going back to Indigo.

Say no to naked p2 repositories!

The standard p2 repository generation tools do not create a landing page for the repository. This creates confusion for novice users who try to visit the published repository in a web browser and get the 404 (not found) error. Beyond novice users, developers and integrators are hampered by inability to easily browse repository content in a web browser.

To save the world from this travesty, I have created a toolkit that can generate a landing page with installation instructions and the content listing pages. These tools are accessible through Ant or directly on the command line.

The landing page contains instructions on how to use Eclipse install software wizard along with a link to browse the repository content.

The repository content pages show all files and folders along with size information. The listing pages have some interesting features that are worth highlighting.

1. Size information is listed for folders, not just files
2. Relative sizes are presented with a sparkline on the right
3. A summary at the bottom shows the number of folders, the number of files, the total size and the last modified date

I have put this to use on all Sapphire releases and builds today. I am also making it available for other projects and companies to use, under EPL terms, of course.

Download (Source)

The toolkit includes two utilities of interest to those wishing to dress up a p2 repository.

GenFolderListing - generates the content listing pages for the specified folder and all child folders

GenRepositoryLanding - generates a repository landing page with installation instructions and the content listing pages

Note that you don’t need to run both tools as GenRepositoryLanding leverages GenFolderListing internally.

Ant Usage

First, import the toolkit...

<import file="sapphire-releng-tools.xml"/>

Alternatively, the jar can be used by itself without the library xml file, but the matching targets will not be available. This may be sufficient if the only requirement is to integrate the tools into the flow of another target.

<taskdef resource="org/eclipse/sapphire/releng/antlib.xml">
  <classpath>
    <pathelement location="sapphire-releng-tools.jar"/>
  </classpath>
</taskdef>

Once the toolkit is imported, use the tools as part of your own target...

<gen-folder-listing folder="${folder}"/>

<gen-repository-landing repository="${repository}" name="${name}"/>

or by calling the provided targets directly...

ant gen-folder-listing -Dfolder=[folder]

ant gen-repository-landing -Drepository=[repository] -Dname=[name]

Command Line Usage

java -cp sapphire-releng-tools.jar org.eclipse.sapphire.releng.listing.GenFolderListingOp [folder]

java -cp sapphire-releng-tools.jar org.eclipse.sapphire.releng.landing.GenRepositoryLandingOp [repository] [name]

Sapphire 8 : Outline Decorations

Multiple text decorations can now be added to the nodes in the master-details editor page outline in order to show additional information in a way that is set apart from the main node label.

A definition of a text decoration is composed of text and an optional color. Both of these properties support Sapphire EL. When text is null, the decoration is not shown. Multiple decorations can be specified for one node.

<node-factory>
    <property>Categories</property>
    <case>
        <label>${ Name == null ? "Uncategorized" : Name }</label>
        <text-decoration>
            <text>${ ( Items.Size == 0 ? null : Concat( "(", Items.Size, ")" ) ) }</text>
        </text-decoration>
    </case>
</node-factory>

The framework API has changed accordingly.

@Label( standard = "text decoration" )
@XmlBinding( path = "text-decoration" )

public interface TextDecorationDef extends Element
{
    ElementType TYPE = new ElementType( TextDecorationDef.class );
    
    // *** Text ***
    
    @Type( base = Function.class )
    @Label( standard = "text" )
    @Required
    @XmlBinding( path = "text" )
    
    ValueProperty PROP_TEXT = new ValueProperty( TYPE, "Text" );
    
    Value<Function> getText();
    void setText( String value );
    void setText( Function value );
    
    // *** Color ***
    
    @Type( base = Function.class )
    @Label( standard = "color" )
    @DefaultValue( text = "#957D47")
    @XmlBinding( path = "color" )
    
    ValueProperty PROP_COLOR = new ValueProperty( TYPE, "Color" );
    
    Value<Function> getColor();
    void setColor( String value );
    void setColor( Function value );
}

public interface MasterDetailsContentNodeDef
{
    // *** Decorations ***
    
    @Type( base = TextDecorationDef.class )
    @Label( standard = "decorations" )
    @XmlListBinding( path = "" )
    
    ListProperty PROP_DECORATIONS = new ListProperty( TYPE, "Decorations" );
    
    ElementList<TextDecorationDef> getDecorations();
}

public final class TextDecoration
{
    public String text()
    public Color color()
}

public final class MasterDetailsContentNodePart
{
    public List<TextDecoration> decorations()
}

Sapphire 8 : Check Box Group

Sapphire already includes a slush bucket and a check box list presentation alternatives for a possible values list.

However, in some cases where the set of possible values is known to always be small, a more compact presentation is desired. The new check box group presentation fills this need.

The check boxes can be arranged either horizontally or vertically.

The presentation will utilize ValueImageService and ValueLabelService, if present on the list entry's value property. The services must be attached to the value property's global service context.

Applicability

1. The property is a list property
2. The list property has a PossibleValuesService
3. There is exactly one possible member type
4. The member type has exactly one property and that property is a value property
5. The value property has @Unique annotation

Automatic Activation

This presentation does not activate automatically.

Manual Activation

The following style codes will activate this presentation as long as the applicability conditions are met.

• Sapphire.PropertyEditor.CheckBoxGroup - produces horizontal presentation
• Sapphire.PropertyEditor.CheckBoxGroup.Horizontal
• Sapphire.PropertyEditor.CheckBoxGroup.Vertical

<property-editor>
    <property>Colors</property>
    <style>Sapphire.PropertyEditor.CheckBoxGroup.Vertical</style>
</property-editor>

Sapphire 8 : Event Suspension

Model events can now be suspended while performing a multi-step operation. This can be helpful in avoiding distracting flashing of the UI as the model goes through the intermediate states.

Element
{
    /**
     * Suspends all events related to this element and everything beneath it in the model tree. The suspended
     * events will be delivered when the suspension is released.
     * 
     * @return a handle that must be used to release the event suspension
     */
    
    Disposable suspend()
}

Property
{
    /**
     * Suspends all events related to this property and everything beneath it in the model tree. The suspended
     * events will be delivered when the suspension is released.
     * 
     * @return a handle that must be used to release the event suspension
     */
    
    Disposable suspend()
}

final ElementList<PurchaseOrderEntry> entries = po.getEntries();
final Disposable suspension = entries.suspend();

try
{
    final PurchaseOrderEntry entry = entries.insert();
    entry.setItem( "USB Cable" );
    entry.setQuantity( 2 );
    entry.setUnitPrice( "2.5" );
}
finally
{
    suspension.dispose();
}
