A SAS package is an automatically generated, single, stand alone zip file containing organised and ordered code structures, created by the developer and extended with additional automatically generated "driving" files (i.e. description, metadata, load, unload, and help files).

The purpose of a package is to be a simple, and easy to access, code sharing medium, which will allow: on the one hand, to separate the code complex dependencies created by the developer from the user experience with the final product and, on the other hand, reduce developer's and user's unnecessary frustration related to a remote deployment process.

In this repository we are presenting the SAS Packages Framework which allows to develop and use SAS packages. The latest version of SPF is 20210204.

To get started with SAS Packages try this Getting Started with SAS Packages presentation (see the ./SPF/Documentation directory).

The documentation and more advance reading would be the SAS(r) packages - the way to share (a how to)- Paper 4725-2020 - extended.pdf article (see the ./SPF/Documentation directory).

Short description of the SAS Packages Framework macros can be found here

The User:

To use a package:

Create a folder for your packages, under Windows OS family, e.g. C:/SAS_PACKAGES or under Linux/UNIX OS family, e.g. /home/<username>/SAS_PACKAGES.

and then either:

Download the SPFinit.sas file (the SAS Packages Framework) into the local packages folder.
[Optional] Manually download the <packageName>.zip file into the local packages folder.
and Execute:

filename packages "<directory/containing/packages/>"; /* setup directory for packages */
%include packages(SPFinit.sas); /* enable the framework */

/* %installPackage(packageName) */ /* install the package, unless you downloaded it manually */

%helpPackage(packageName)    /* get help about the package */
%loadPackage(packageName)    /* load the package content into the SAS session */

or if you need it just for "one time" only Execute:

filename packages "%sysfunc(pathname(work))"; /* setup temporary directory for packages in the WORK */
filename SPFinit url "https://raw.githubusercontent.com/yabwon/SAS_PACKAGES/main/SPF/SPFinit.sas";
%include SPFinit; /* enable the framework */

%installPackage(packageName) /* install the package */
%helpPackage(packageName)    /* get help about the package */
%loadPackage(packageName)    /* load the package content into the SAS session */

The Developer:

To create your own package:

Read the SAS(r) packages - the way to share (a how to)- Paper 4725-2020 - extended.pdf to learn more details.
Download and use the SPFinit.sas file (the SAS Packages Framework), the part of the framework required for testing is there too.

Update[October 15th, 2020]: %previewPackage() macro is available.

Update[September 11th, 2020]: %loadPackageS() and %verifyPackage() macros are available.

Update[July 30th, 2020]: All components of SAS Packages Framework are now in one file SPFinit.sas (located in the ./SPF directory). Documentation moved to ./SPF/Documentation directory. Packages zip files moved to ./packages directory.

Update[June 10th, 2020]: To see help info about framework macros and their parameters just run: %generatePackage(), %installPackage(), %helpPackage(), %loadPackage(), and %unloadPackage() with empty parameter list.

Update[June 3rd, 2020]: %installPackage() macro is available. The %installPackage() macro is embedded in the loadpackage.sas part of the framework.

Available packages:

Currently the following packages are available (see the ./packages directory):

SQLinDS[2.2], based on Mike Rhoads' article Use the Full Power of SAS in Your Function-Style Macros. The package allows to write SQL queries in the data step, e.g.

  data class;
    set %SQL(select * from sashelp.class order by age);
  run;

Documentation for MacroCore

DFA (Dynamic Function Arrays)[0.5], contains set of macros and FCMP functions which implement: a dynamically allocated array, a stack, a fifo queue, an ordered stack, and a priority queue, run %helpPackage(DFA,createDFArray) to find examples.

Documentation for DFA

macroArray[0.8], implementation of an array concept in a macrolanguage, e.g.

  %array(ABC[17] (111:127), macarray=Y); 
  
  %macro test();
    %do i = 1 %to 17; 
      %put &i.) %ABC(&i.); 
    %end;
  %mend;
  %test() 
  
  %let %ABC(13,i) = 99999; /* i = insert */

  %do_over(ABC, phrase=%nrstr( 
      %put &_i_.%) %ABC(&_i_.); 
      ),
      which = 1:H:2
  );

Documentation for macroArray

BasePlus[0.991] adds a bunch of functionalities I am missing in BASE SAS, such as:

call arrMissToRight(myArray); 
call arrFillMiss(17, myArray); 
call arrFill(42, myArray); 

rc = delDataset("DataSetToDrop"); 

string = catXFn("date9.", "#", myArray);

format x bool.;

%put %getVars(sashelp.class, pattern = ght$, sep = +, varRange = _numeric_);
