## SAS Packages Framework, version 20221121

---

### New feature of "Cherry picking" added to the SAS Packages Framework.
Sometimes a package offers so many features that the number may be "overwhelming".
In such case only some of them may be selected for loading. Such process
is called a "cherry picking". The feature is provided by the `%loadPackage()` macro 
which uses a `cherryPick=` parameter (see description below).

For example, execution of the following code:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
 %loadPackage(BasePlus, cherryPick=rainCloudPlot getVars)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
results with loading only the `rainCloudPlot` and the `getVars` elements.
If several object types (e.g., a macro and a format) share the same name 
all will be loaded.


What is the trade-off?
- Since the cherry picking selects only a part of the package the `SYSloadedPackages` 
macrovariable is not updated with the package name.
- Dependencies i.e., packages from the `ReqPackages` list, are not loaded automatically, 
so they have to be loaded manually.
- The `%unloadPackage()` macro executed on such partially loaded package may issue 
some (irrelevant) warnings.

---

### Changes in `%loadPackage()` macro:
- New `cherryPick=` parameter added to the macro.
  As a value a *space separated* list of selected elements 
  of the package to be loaded into the SAS session is expected.
  Default value of an asterisk (`*`) means: "load all elements of the package".
  Empty list is equivalent to default.
- Documentation updated.

### Changes in `%generatePackage()` macro:
- Code adjustment for the cherry picking feature.
- Minor additional code refactoring.
- The `%ICEloadPackage()` macro does not support cherry picking.

---

- DFA [0.5.2]
- dynMacroArray [0.2.2]
