 # 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.

+
+ Macro to get previwe of a SAS packages, version `20211111`
+
+ 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:
+                        `%previewPackage(myPackage).`
+                       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:
+                        `%previewPackage(PiPackage, , zip=disk, options=)`

+
+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.
+
+
+*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.

+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

+
+*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.

+## >>> `%mcHashTable()` macro: <<< <a name="mchashtable-macro"></a> #######################
+
+The `%mcHashTable()` macro provided in the package 
+is designed to facilitate the idea of a "macro hash table" 
+concept, i.e. *a list of macrovariables with common prefix 
+and suffixes generated as a hash digest* which allows 
+to use values other than integers as indexes.
+
+The `%mcHashTable()` macro allows to generate other macros 
+which behaves like hash tables or dictionaries. See examples below.
+
+The `%mcHashTable()` macro executes like a pure macro code.

+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~sas
+%mcHashTable(
+   H
+  <,METHOD>
+  <,HASH=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `H`      - *Required*, a hash table macro name and a declaration/definition, 
+              e.g. `mcHashTable(HT)`. It names a macro which is generated by
+              the `%mcHashTable()` macro. Provided name cannot be empty 
+              or an underscore (`_`). No longer than *16* characters.
+
+2. `METHOD` - *Optional*, if empty (or DECLARE or DCL) then the code of 
+              a macro hash table is compiled.
+              If `DELETE` then the macro hash table named by `H` and all 
+              macrovariables named like "`&H._`" are deleted.
+
+* `HASH=`   - *Optional*, indicates which hashing algorithms should be used,
+              available values are `CRC32` or `MD5`, the `CRC32` is the default.  
+
+---
+
+### THE CREATED MACRO `%&H.()`: ####################################################
+
+The created macro imitates behaviour of a hash table or a dictionary. 
+It is *not* dedicated for "long-ish" lists (above 1000 elements) since 
+the performance may be poor.
+
+The basic syntax is the following, the `<...>` means optional parameters:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~sas
+%&H.(
+  METHOD
+  <,KEY=> 
+  <,DATA=>
+)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Arguments description**:
+
+1. `METHOD` - *Required*, indicate what behaviour should be executed. 
+              Allowed values are:
+                - `ADD`, adds key and data portion to the macro hash table,
+                   *multiple data portions* are available for one key.
+                - `FIND`, tests if given key exists in the macro hash table
+                   and, if yes, returns data value associated with the key.
+                   For multiple data portions see the `data=` parameter.
+                - `DP` (data portion) or `CHECK`, returns the number of data
+                   portions for a given key.
+                - `CLEAR` removes all data and keys values.
+                - `KEYIDX`, allows to get data by the key index rather than value.
+                - `KEYVAL`, returns key value for a given key index.
+                - `CHECKIDX`, returns the number of data portions for 
+                   a given key index. 
+
+* `KEY=`    - *Optional*, provides key value for `ADD`, `FIND`,`DP`, `CHECK`
+              `CHECKIDX`, `KEYIDX`, and `KEYVAL` methods. Leading and trimming 
+              spaces are removed from the value.
+              The `hashing(CRC32,...)` function or the `MD5(...)` function is 
+              used to generate the hash.
+
+* `DATA=`   - *Optional*, provides data value for the `ADD` method and 
+              for the`FIND` method provides data portion number to be 
+              extracted. Default value is `1` (used by the `FIND` method).
+
+
+When macro is executed and when data are added the following types of 
+*global* macrovariables are created:
+- `&H._########`,
+- `&H._########_Xk`,
+- `&H._########_Xi`,
+- `&H._########_Xi_j`,
+- `&H._KEYNUM`,
+- and `&H._KEY_i`.
+
+The `#` represents value generated by the `hashing(CRC32,...)` function 
+or the `MD5(...)` function for the given key.
+
+The first type keeps information about possible collision for the key.
+
+The second type keeps information about value of a given key, 
+the `X` keeps the track of other colliding keys.
+
+The third type keeps information about number of data portions 
+for given key, the `X` keeps the track of other colliding keys.
+
+The fourth type keeps the data portion, the `j` indicates data portion number.
+
+The fifth type keeps the number of unique values of the key.
+
+The sixth type keeps the list of unique values of the key, 
+the `i` indicates key number.
+
+See examples below to see use cases.

+## >>> `%QzipArrays()` macro: <<< <a name="qziparrays-macro"></a> #######################  
+
+The zipArrays() and QzipArrays() macros
+allow to use a function on elements of pair of 
+macro arrays. 
+
+For two macroarrays the corresponding 
+elements are taken and the macro applies a function, provided by user, 
+to calculate result of the function on taken elements. 
+
+When one of the arrays is shorter then elements are, by default, 
+"reused" starting from the beginning. But this behaviour can be altered. 
+See examples for the details.
+
+By default newly created macroarray name is concatenation 
+of first 13 characters of names of arrays used to create the new one, 
+e.g. if arrays names are `abc` and `def` then the result name is `abcdef`,
+if arrays names are `abcd1234567890` and `efgh1234567890` then the result 
+name is `abcd123456789efgh123456789` 
+
+The `zipArrays()` returns unquoted value [by `%unquote()`].
+The `QzipArrays()` returns quoted value [by `%superq()`].
+
+See examples below for the details.
+
+The `%QzipArrays()` macro executes like a pure macro code.

+## >>> `%zipArrays()` macro: <<< <a name="ziparrays-macro"></a> #######################  
+
+The zipArrays() and QzipArrays() macros
+allow to use a function on elements of pair of 
+macro arrays. 
+
+For two macroarrays the corresponding 
+elements are taken and the macro applies a function, provided by user, 
+to calculate result of the function on taken elements. 
+
+When one of the arrays is shorter then elements are, by default, 
+"reused" starting from the beginning. But this behaviour can be altered. 
+See examples for the details.
+
+By default newly created macroarray name is concatenation 
+of first 13 characters of names of arrays used to create the new one, 
+e.g. if arrays names are `abc` and `def` then the result name is `abcdef`,
+if arrays names are `abcd1234567890` and `efgh1234567890` then the result 
+name is `abcd123456789efgh123456789` 
+
+The `zipArrays()` returns unquoted value [by `%unquote()`].
+The `QzipArrays()` returns quoted value [by `%superq()`].
+
+See examples below for the details.
+
+The `%zipArrays()` macro executes like a pure macro code.
