SAS_PACKAGES - a SAS Packages Framework and Repository

---

Intro:

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 20210528.

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 Packages - The Way to Share (a How-To) - Paper 4725-2020 - extended version article to learn more details.
• Read the My First SAS Package: A How-To - Paper 1079-2021 article available at communities.sas.com here or locally here
• 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;

SHA256 digest for SQLinDS: 1853CD6262CF66582A33C373AA612CA714B61CB88A1C51745E7A57D5A03C39B4

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[0.992] 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_);

• GSM (Generate Secure Macros)[0.14], package allows to create secured macros stored in SAS Proc FCMP functions. The dataset with functions can be shared between different operating systems and allows to generate macros on site without showing their code.
