Dynamic String Substitution Variables

Identifier:
org.eclipse.core.variables.dynamicVariables

Since:
3.0

Description:
This extension point provides a mechanism for defining dynamic variables used in string substitution. The value of a dynamic variable is resolved at the time a string substitution is performed, with an optional argument.

Configuration Markup:

<!ELEMENT extension ( variable*)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED

>

  • point - a fully qualified identifier of the target extension point
  • id - an optional identifier of the extension instance
  • name - an optional name of the extension instance

<!ELEMENT variable EMPTY>

<!ATTLIST variable

name             CDATA #REQUIRED

resolver         CDATA #REQUIRED

description      CDATA #REQUIRED

supportsArgument (true | false)

>

  • name - specifies a unique name for this variable.
  • resolver - specifies a Java class which implements org.eclipse.core.variables.IDynamicVariableResolver, which is used to determine the value of the variable
  • description - specifies a human-readable description of this variable
  • supportsArgument - Whether this variable supports an argument. When unspecified, the implied value is true.

Examples:
The following is a definition of a dynamic variable that resolves to the name of the selected resource:

 <extension point=
"org.eclipse.core.variables.dynamicVariables"
>
   <variable 
      name=
"resource_name"

      expanderClass=
"com.example.ResourceNameExpander"

      description=
"The name of the selected resource"
>
   </variable>
 </extension>
