Can I induce a default choice or contribute attribute rules? [message #1802547]

I'm playing now with a Project Catalog and Project setups.

I noted that while setting a git clone I can add the following annotation to the org.eclipse.oomph.setup.git.GitCloneTask :

<?xml version="1.0" encoding="UTF-8"?>
<base:Annotation
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:base="http://www.eclipse.org/oomph/base/1.0"
    source="http://www.eclipse.org/oomph/setup/InducedChoices">
  <detail key="inherit">
    <value>github.remoteURIs</value>
  </detail>
  <detail key="label">
    <value>${scope.project.label} Github repository</value>
  </detail>
  <detail key="target">
    <value>remoteURI</value>
  </detail>
</base:Annotation>

That annotation makes install ui tol present a "Git clone location rule" combobox with some choices.

I also noted that after I have installed my ide once those items were created in my user.setup file:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0">
  <setup:AttributeRule
      attributeURI="http://www.eclipse.org/oomph/setup/1.0#//InstallationTask/location"
      value="${install.root/}${installation.id}"/>
  <setup:AttributeRule
      attributeURI="http://www.eclipse.org/oomph/setup/1.0#//WorkspaceTask/location"
      value="${workspace.container.root/}${workspace.id}"/>
  <setup:AttributeRule
      attributeURI="http://www.eclipse.org/oomph/setup/git/1.0#//GitCloneTask/location"
      value="${git.container.root/}${@id.remoteURI|gitRepository}-${@id.checkoutBranch}"/>
</xmi:XMI>

Seems that those values are the latest selected by me in the Variables UI.

So, can I induce the UI to present a specific item in the combobox ?
can I contribute attribute rules / items to those combobox ?

thanks

The "inherit" key of the "InducedChoices" annotation can point to multiple whitespace-separated variables. In your example it points to the "github.remoteURIs" variable, which is defined in the Github project catalog (com.github.projects.setup) as follows:

<?xml version="1.0" encoding="UTF-8"?>
<setup:VariableTask
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0"
    name="github.remoteURIs"
    label="Github repository">
  <choice value="git@github.com:@{remoteURI}.git"
      label="Git (read-write)"/>
  <choice value="https://${github.user.id|username}@github.com/@{remoteURI}.git"
      label="HTTPS (read-write)">
    <annotation
        source="http://www.eclipse.org/oomph/setup/MatchChoice"/>
  </choice>
  <choice value="https://github.com/@{remoteURI}.git"
      label="HTTPS (read-only, anonymous)"/>
  <description>Choose from the available Github URIs</description>
</setup:VariableTask>

You can change the annotation to inherit the choices of a different or an additional variable.

Hi Eike, thanks !

One doubt about inherit:
I noted that the com.github.projects.setup is always being loaded in both Project or Project Catalog models.
This means that if I'm about to create my own Project Catalog I do not need to duplicated the variables created there, right ?

But if I want to modify the "github.remoteURIs", it is allowed to "override" it in my own Project Catalog using the same name or do I need to create other variable using another name ?

If I create one variable in my Project Catalog I will need to load its model in all Projects that I will create, right?

A new choice variable in your own project catalog is fine. You don't need to inherit from the ones we provide. The tasks in your project catalog will always be available in the contained projects.

OK Eike, I got it. thanks.

And about the git clone location... I'm seeing a Unresolved Variables for it in the project's Outline view, but I was not able to find nothing related to it in the parent models... it is created programmatically ?

would be possible to add variable choices to it too ?

It's okay that the git clone location variable appears unresolved at authoring time. At install time the user can pick one of the shipped attribute rules or enter a custom attribute rule (IIRC). The shipped attribute rules are defined in https://git.eclipse.org/c/oomph/org.eclipse.oomph.git/tree/plugins/org.eclipse.oomph.setup.git/model/Git.ecore#n27 :

    <eStructuralFeatures xsi:type="ecore:EAttribute" name="location" lowerBound="1"
        eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString" defaultValueLiteral="">
      <eAnnotations source="http://www.eclipse.org/oomph/setup/Variable">
        <eAnnotations source="Choice">
          <details key="value" value="${installation.location/git/}${@id.remoteURI|gitRepository}"/>
          <details key="label" value="Located in a folder named 'git/&lt;repo>' within the installation folder"/>
        </eAnnotations>
        <eAnnotations source="Choice">
          <details key="value" value="${workspace.location/.git/}${@id.remoteURI|gitRepository}"/>
          <details key="label" value="Located in a folder named '.git/&lt;repo>' within the workspace folder"/>
        </eAnnotations>
        <eAnnotations source="Choice">
          <details key="value" value="${git.container.root/}${@id.remoteURI|gitRepository}-${@id.checkoutBranch}"/>
          <details key="label" value="Located in a folder named '&lt;repo>-&lt;branch>' within the root Git-container folder "/>
        </eAnnotations>

      </eAnnotations>

        <details key="type" value="FOLDER"/>

        <details key="defaultValue" value="${user.home}"/>
        <details key="description" value="The root Git-container folder where all the Git clones are located"/>
        <details key="storageURI" value="scope://"/>
      </eAnnotations>
    </eStructuralFeatures>

I don't think you can offer custom attribute rule choices for the git clone location. The attribute rule that the user selects/enters is stored in user.setup.
