SAS Packages Framework, version 20250710
Changes:
- Framework's code cleanup: all uses of the autocall `%lowcase()` macro were removed or replaced by `%sysfunc(lowcase(...))` call.
- Formatting of the default MIT license text in the `%generatePackage()` macro was changed.
- The `sourcePath=` parameter in the `%installPackage()` macro now allows both quoted and un-quoted address.
- Documentation updated.

%put # Macro to unload SAS packages, version `20250710` #;
|
|
%put # #;
|
|
%put # A SAS package is a zip file containing a group #;
|
|
%put # of SAS codes (macros, functions, data steps generating #;
|
|
%put # data, etc.) wrapped up together and provided with #;
|
|
%put # a single `unload.sas` file (also embedded inside the zip). #;
|
|
%put # #;
|
|
%put # The `%nrstr(%%unloadPackage())` macro clears the package content #;
|
|
%put # from the SAS session. #;
|
|
%put # #;
|
|
%put #-------------------------------------------------------------------------------#;
|
|
%put # #;
|
|
%put #### Parameters: #;
|
|
%put # #;
|
|
%put # 1. `packageName` *Required.* Name of a package, e.g. myPackage, #;
|
|
%put # Required and not null, default use case: #;
|
|
%put # `%nrstr(%%unloadPackage(myPackage)).` #;
|
|
%put # If empty displays this help information. #;
|
|
%put # #;
|
|
%put # - `path=` *Optional.* Location of a package. By default it #;
|
|
%put # looks for location of the **packages** fileref, i.e. #;
|
|
%put # `%nrstr(%%sysfunc(pathname(packages)))` #;
|
|
%put # #;
|
|
%put # - `options=` *Optional.* Possible options for ZIP filename, #;
|
|
%put # default value: `LOWCASE_MEMNAME` #;
|
|
%put # #;
|
|
%put # - `source2=` *Optional.* Option to print out details about #;
|
|
%put # what is loaded, null by default. #;
|
|
%put # #;
|
|
%put # - `zip=` Standard package is zip (lowcase), #;
|
|
%put # e.g. `%nrstr(%%unloadPackage(PiPackage))`. #;
|
|
%put # If the zip is not available use a folder. #;
|
|
%put # Unpack data to "pipackage.disk" folder #;
|
|
%put # and use unloadPackage in the following form: #;
|
|
%put # `%nrstr(%%unloadPackage(PiPackage, zip=disk, options=))` #;
