**SAS Packages Framework**, version `20221002` - Modifications in the `%installPackage()` macro it is allowed to call installation of packages with version number (if used with `mirror=0`), for example: `%installPackage(baseplus(1.17) macroarray(1.0) dfa(0.5) GSM)`, - For the `%installPackage()` and in the `%loadPackageS()` macros the list of packages standardised before execution to the form `package1(ver1) package2(ver2) package3(ver3)`, - Fix for directories "with spaces" for `%installPackage()`. - Documentation updated.

%put # #;
|
|
%put # Macro to *load* SAS packages, version `20221002` #;
|
|
%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 included by #;
|
|
%put # a single `load.sas` file (also embedded inside the zip). #;
|
|
%put # #;
|
|
%put # The `%nrstr(%%loadPackage())` macro loads package content, i.e. macros, #;
|
|
%put # functions, formats, etc., from the zip into the SAS session. #;
|
|
%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(%%loadPackage(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 # - `requiredVersion=` *Optional.* Option to test if the loaded #;
|
|
%put # package is provided in required version, #;
|
|
%put # default value: `.` #;
|
|
%put # #;
|
|
%put # - `lazyData=` *Optional.* A list of names of lazy datasets to be #;
|
|
%put # loaded. If not null datasets from the list are loaded #;
|
|
%put # instead of the package. #;
|
|
%put # An asterisk (*) means *load all lazy datasets*. #;
|
|
%put # #;
|
|
%put # - `zip=` Standard package is zip (lowcase), #;
|
|
%put # e.g. `%nrstr(%%loadPackage(PiPackage))`. #;
|
|
%put # If the zip is not available use a folder. #;
|
|
%put # Unpack data to "pipackage.disk" folder #;
|
|
%put # and use loadPackage in the following form: #;
|
|
%put # `%nrstr(%%loadPackage(PiPackage, zip=disk, options=))` #;
