 # 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.

+
+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 **`20220420`**.  
+
+**To get started with SAS Packages** try this [**`Getting Started with SAS Packages`**](https://github.com/yabwon/SAS_PACKAGES/blob/main/SPF/Documentation/Getting_Started_with_SAS_Packages.pdf "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`**](https://github.com/yabwon/SAS_PACKAGES/blob/main/SPF/Documentation/SAS(r)%20packages%20-%20the%20way%20to%20share%20(a%20how%20to)-%20Paper%204725-2020%20-%20extended.pdf "SAS packages - the way to share") article (see the `./SPF/Documentation` directory).
+
+
+*Note:* Filenames references `packages` and `package` are reserved keywords.
+The first one should be used to point local folder with packages and the framework.
+The second is used internally by macros.
+After assigning the directory do not change them when using the SPF since it may affect stability of the framework.

+ A SAS package is a zip file containing a group
+ of SAS codes (macros, functions, data steps generating
+ data, etc.) wrapped up together and provided with
+ a single `preview.sas` file (also embedded inside the zip).
+
+ The `%previewPackage()` macro prints, in the SAS log, content
+ of a SAS package. Code of a package is printed out.
+
+-------------------------------------------------------------------------------
+
+### Parameters:
+
+ 1. `packageName`      *Required.* Name of a package, e.g. myPackage,
+                       Required and not null, default use case:

+                       If empty displays this help information.
+
+ 2. `helpKeyword`      *Optional.*  A phrase to search in preview,
+                       - when empty prints description,
+                       - "*" means: print all preview,
+                       - "license" prints the license.
+
+ - `path=`             *Optional.* Location of a package. By default it
+                       looks for location of the **packages** fileref, i.e.
+                        `%sysfunc(pathname(packages))`
+
+ - `options=`          *Optional.* Possible options for ZIP filename,
+                       default value: `LOWCASE_MEMNAME`
+
+ - `source2=`          *Optional.* Option to print out details about
+                       what is loaded, null by default.
+
+ - `zip=`              Standard package is zip (lowcase),
+                        e.g. `%previewPackage(PiPackage)`.
+                       If the zip is not available use a folder.
+                       Unpack data to "pipackage.disk" folder
+                       and use previewPackage in the following form:

+# The GSM package [ver. 0.20] <a name="gsm-package"></a> ###############################################
+
+The **GSM** (a.k.a. *Generate Secure Macros*) package allows
+to create secured macros stored in SAS Proc FCMP functions.
+The dataset with functions can be shared and allows to generate 
+macros without showing their code.
+
+The GSM package is basically an automated version of the following:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+proc fcmp outlib = work.gsm.secure ENCRYPT;
+  function generateMacro() $;
+    rc = RESOLVE('
+      %macro secretMacro(x) / SECURE;
+        data test;
+         a = "&x.";
+        run;
+      %mend;
+    ');
+    return (rc);
+  endsub;
+run;
+
+/* share work.gsm dataset */
+options cmplib = work.gsm;
+data _null_;
+  rc = generateMacro();
+  put rc=;
+run;
+
+/* enjoy */
+%secretMacro(42)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+See examples for more details.
+
+Recording of presentation with "how it works" description, in Polish, is avaliable [here](https://www.youtube.com/watch?v=LtaWPe2sgRY&t=1s).
+
+*How to use it:* 
+ - Copy all files with your secured macros code into a directory. 
+   Best approach is to have one file for one macro.
+ - Copy a path to the directory.
+ - Run the following code:
+   ```
+   %GSM(<the path to directory>, cmplib=<name of the dataset>)
+   ```
+ - Share generated `ZIP` file (unzip and run the code).
+ 
+**Limitations:** 
+ - Single macro file cannot be longer than 32760 bytes.
+ 
+ - Multiline text variable. Consider the following code text file:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+%macro~test()/SECURE;~#@
+data~test;~#@
+a~=~"abc~#@
+~#@
+def";~#@
+put~a~hex20.;~#@
+run;~#@
+%mend~test;~#@
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+where `~` symbols the space character, 
+`#` symbols the carriage return (`0D`), 
+and `@` symbols the line feed (`0A`).
+The code file is scanned and inserted into 
+the `resolve()` function argument in a "byte by byte"
+fashion hence also the "end of line" characters are included.
+As the result value of variable `a` will be: 
+
+`a = "abc~#@~#@def"`. 
+
+If you want to use the `GSM` package avoid 
+such "style" of coding in your macros.
+

+
+ 
+## >>> `%GSM()` macro: <<< <a name="gsm-macro"></a> #######################
+
+The `%GSM()` macro is the main macro of 
+the **GSM** (a.k.a. *Generate Secure Macros*) package. 
+
+It converts a list of macros provided by the user into
+a data set of the Proc FCMP functions. The macros are stored
+in functions are encrypted which allow to share them without 
+showing their code. *Important* thing is that macros provided 
+by the user *has* to be "secure", i.e. the `secure` option has to 
+be added to the macro definition. See the example:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%macro secretMacro(x) / SECURE; /* <- the secure option */
+  <... some code ...>
+%mend secretMacro;
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+As a result a zip file, containing dataset with functions and 
+code to be executed on site, is generated.
+
+Since encrypted code is stored in a SAS dataset it has
+no limitation in sharing between operating systems (like catalogs have).
+
+*Limitation:* Due to the `Resolve()` function limitations 
+ a single macro file cannot be longer than 32760 bytes.
+
+*Notes:* 
+- All macros have to have the `secure` option added, i.e. `%macro aMacroname(...) / SECURE ;`.
+- During the execution a test macro, named `%GSMpck_dummyMacroForTests()`, is generated.
+- The `%GSM()` macro calls the `%GSMpck_makeFCMPcode(...)` macro internally.

+### SYNTAX: ###################################################################
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%GSM( 
+   path
+ <,trim=0>
+ <,cmplib=work.generateMacros>
+ <,source2=>
+ <,outpath=>
+ <,encodingRestricted=>
+ <,secret=>
+ <,lineEnd=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `path`               - *Required*, indicates a directory which contains files with macros.
+                          Only files with `sas` extension are used.
+
+* `cmplib=`             - *Optional*, the default value is `work.generateMacros`. 
+                          Names the dataset which will contain generated functions. 
+
+* `source2=`            - *Optional*, the default value is null. 
+                          Indicate if `%includ`-ed files are printed out.
+                          Any value other than null enables printing.
+
+* `outpath=`            - *Optional*, the default value is set the same as the `path`.
+                          Points a directory in which a result (a zip file) is generated.
+
+* `encodingRestricted=` - *Optional*, the default value is `0`.
+                          If set to 1 then if User session encoding is different from 
+                          encoding of the session which generates the dataset then 
+                          the generateMacros() function will not execute macro code.
+
+* `secret=`             - *Optional*, the default value is null, in such case the 
+                          secret is generated from the `sha256(datetime(), hex32.)` function 
+                          and is printed in the log. When not null then should be
+                          alphanumerical constant. Non-alphanumerical characters are removed.
+                          Required to execute the `resolve()` function. 
+                          User who do not know the value will not be able
+                          to run the `_maxro_XX_()` function.
+
+* `lineEnd=`            - *Optional*, the default value is `0D0A`, indicates which of:
+                          line feed, carriage return, or both, or a space be inserted 
+                          at the end of line in the intermediate code file that is generated.
+                          Value has to be hexadecimal code (_NOT_ null),
+                          since the value is resolved as `"&lineEnd."x`, so use e.g.
+                          `0A` for line feed, `0D` for carriage return, 
+                          `0D0A` for both, and `20` for space.
+
+* `trim=`               - *Deprecated*, the default value is `0`.
+                          *Kept for backward compatibility.*
