Added​

  • Added comment format for .yml files.

Changed​

  • Changed ArtifactPathBuilder to use scoped caching instead of a globally contested cache.

8.9.1 (2026-07-16)​

Fixed​

8.9.0 (2026-06-30)​

Fixed​

  • Fixed elementType filtering on ExpandersExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact. and ExpansionSteps to take 'component' into account.

8.7.0 (2026-02-19)​

Added​

  • Added full program context to the provided ElementTagResolver by using the factory.

  • Use the provided ElementTagResolver for NativeType resolution.

8.6.0 (2026-01-19)​

Added​

  • Added dependencies mapping var to retrieve program and module dependencies.

8.5.0 (2025-11-18)​

Added​

  • Added List<T> accessor distinct to get a new list with all unique values in mappings.
  • Added List<T> accessor first to get the first value of a list if it exists (otherwise an exception).
  • Added List<T> accessor firstOrNull to get the first value of a list if it exists (otherwise a null value).
  • Added List<T> accessor last to get the last value of a list if it exists (otherwise an exception).
  • Added List<T> accessor lastOrNull to get the last value of a list if it exists (otherwise a null value).
  • Added List<T> accessor reverse to create a new list in reverse order.

8.4.0 (2025-11-05)​

Added​

  • Added option module.harvest.allowImported to be able to harvest imported modules.

Changed​

  • Option harvest.skip now works for module types.

8.3.0 (2025-10-24)​

Changed​

  • Updated dependencies:
    • org.apache.commons:commons-lang3: 3.17.0 > 3.18.0 (CVE-2025-48924)

8.2.4 (2025-06-05)​

Fixed​

  • [mapping] Fixed expansionResource variable binding not pointing to the correct resource for Features due to expanderExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact. variables incorrectly taking precedence over feature variables.

8.2.3 (2025-05-27)​

Fixed​

  • Fixed remaining issue by using ExpansionConfigurationContext instead of ModelLoadingContext.

8.2.2 (2025-05-26)​

Fixed​

  • Fixed expandersExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact. no longer recognising elements with superType under the abstract type name.

8.2.1 (2025-05-20)​

Fixed​

  • [mapping/debug] Fixed matchLineNumber causing a NPE when evaluating IndexProperty.

8.2.0 (2025-05-14)​

Added​

  • [mapping] Added direction attribute to <sorted> which can be ascending or descending. Default is ascending

Changed​

  • Changed sorting behaviour when using <item> or <items> to be more intuitive. Sorting will now occur within <items> instead of on the entire list. If a list mapping contains multiple items mappings, the items will appear in order of appearance in the mapping.

8.1.4 (2025-05-05)​

Fixed​

  • Fixed issue in tests using classic expanderExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact. test api causing error with ExpansionSource variable.
  • [mapping] Changed name attribute in foreach to required.
  • Fixed PropertyMappingException not showing cause error message as intended.

Changed​

8.1.3 (2025-04-29)​

8.1.2 (2025-04-28)​

  • [mapping] Fixed DebugMappingContext not correctly provided in list scope.

8.1.1 (2025-04-25)​

Fixed​

  • [mapping] Fixed order of items in a list mapping when no sorting is defined.
  • [mapping] Fixed order of items when using multiple <item> or <items>.

8.1.0 (2025-04-24)​

Added​

  • Added support for providing Variable bindings. Variables can be provided by implementing net.democritus.expander.variables.ExpanderVariable and registering it as a Service. Add VariableScope annotation to define where the variable is applicable.
  • [mapping] Added new syntax for list
    • foreach adds a new iteration. List mappings can now include multiple iterations.
    • item adds a single item.
    • items adds a number of items based on its internal mapping.
  • [mapping] Added strict attribute to mapping header. If set to true, the mapping will fail when encountering references to unbound variables.
  • [mapping] Added format() function. Can be used to build strings in a compact way. (e.g. format('${component.name}/${dataElement.name.firstToLower}'))

Removed​

  • Removed artifactName variable binding in mapping files.

Fixed​

  • Fix ElementChildRetriever not using interface method for abstract parents. (ported over from expanders-core:7.8.3).

Changed​

  • Improved legibility of ExpanderExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact. stack-traces.
  • Refactored existing variable bindings to ExpanderVariables, including descriptions to make stack-traces more informative.
  • [mapping] Name attributes are now optional in <filter, <distinct>, <foreach>, <sorted>, <item> and <items>.

8.0.0 (2024-11-25)​

Changed​

  • Moved expandersExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact.-core and expandersExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact.-test-utils to expandersExpanderA unit of generation that combines a data tree instance (functional M1 model) with a template to generate an artifact.-core repository.
  • expander-core is no longer a fat jar. Transitive dependencies will now have to be included separately.
