  @brief abort gracefully according to context
  @details Do not use directly!  See bottom of explanation for details.

   Configures an abort mechanism according to site specific policies or the
    particulars of an environment.  For instance, can stream custom
    results back to the client in an STP Web App context, or completely stop
    in the case of a batch run.

  For the sharp eyed readers - this is no longer a macro function!! It became
  a macro procedure during a project and now it's kinda stuck that way until
  that project is updated (if it's ever updated).  In the meantime we created
  `mp_abort` which is just a wrapper for this one, and so we recomend you use
  that for forwards compatibility reasons.

  @param mac= to contain the name of the calling macro
  @param type= deprecated.  Not used.
  @param msg= message to be returned
  @param iftrue= supply a condition under which the macro should be executed.

  not all properties can / will be populated.

  @brief Extract DDL in various formats, by table or library
  @details Data Definition Language relates to a set of SQL instructions used
    to create tables in SAS or a database.  The macro can be used at table or
    library level.  The default behaviour is to create DDL in SAS format.

  Usage:

      data test(index=(pk=(x y)/unique /nomiss));
        x=1;
        y='blah';
        label x='blah';
      run;
      proc sql; describe table &syslast;

      %mp_getddl(work,test,flavour=tsql,showlog=YES)

  @param lib libref of the library to create DDL for.  Should be assigned.
  @param ds dataset to create ddl for
  @param fref= the fileref to which to write the DDL.  If not preassigned, will
    be assigned to TEMP.
  @param flavour= The type of DDL to create (default=SAS). Supported=TSQL
  @param showlog= Set to YES to show the DDL in the log
  @param schema= Choose a preferred schema name (default is to use actual schema
    ,else libref)
  @param applydttm= for non SAS DDL, choose if columns are created with native
   datetime2 format or regular decimal type

  @brief Scans a dataset to find the max length of the variable values
  @details
  This macro will scan a base dataset and produce an output dataset with two
  columns:

  - COL    Name of the base dataset column
  - MAXLEN Maximum length of the data contained therein.

  Character fields may be allocated very large widths (eg 32000) of which the maximum
    value is likely to be much narrower.  This macro was designed to enable a HTML
    table to be appropriately sized however this could be used as part of a data
    audit to ensure we aren't over-sizing our tables in relation to the data therein.

  Numeric fields are converted using the relevant format to determine the width.
  Usage:

      %mp_getmaxvarlengths(sashelp.class,outds=work.myds);

  @param libds Two part dataset (or view) reference.
  @param outds= The output dataset to create

  @file mp_jsonout.sas
  @brief Writes JSON in SASjs format to a fileref
  @details PROC JSON is faster but will produce errs like the ones below if
  special chars are encountered.

     >An object or array close is not valid at this point in the JSON text.
     >Date value out of range

  If this happens, try running with ENGINE=DATASTEP.

  Usage:

        filename tmp temp;
        data class; set sashelp.class;run;
        
        %mp_jsonout(OBJ,class,jref=tmp)

  If you are building web apps with SAS then you are strongly encouraged to use
  the mX_createwebservice macros in combination with [sasjs](https://github.com/macropeople/sasjs).
  For more information see https://sasjs.io

  @param action Valid values:
    * OPEN - opens the JSON
    * OBJ - sends a table with each row as an object
    * ARR - sends a table with each row in an array
    * CLOSE - closes the JSON

  @param ds the dataset to send.  Must be a work table.
  @param jref= the fileref to which to send the JSON
  @param dslabel= the name to give the table in the exported JSON
  @param fmt= Whether to keep or strip formats from the table
  @param engine= Which engine to use to send the JSON, options are:
  * PROCJSON (default)
  * DATASTEP 

  @param dbg= Typically used with an _debug (numeric) option

  @brief An opinionated way to execute DDL files in SAS.
  @details When delivering projects there should be seperation between the DDL
    used to generate the tables and the sample data used to populate them.

  This macro expects certain folder structure - eg:

    rootlib
    |-- LIBREF1
    |  |__ mytable.ddl
    |  |__ someothertable.ddl
    |-- LIBREF2
    |  |__ table1.ddl
    |  |__ table2.ddl
    |-- LIBREF3
       |__ table3.ddl
       |__ table4.ddl

  Only files with the .ddl suffix are executed.  The parent folder name is used
  as the libref.
  Files should NOT contain the `proc sql` statement - this is to prevent
  statements being executed if there is an err condition.

  Usage:

    %mp_runddl(/some/rootlib)  * execute all libs ;

    %mp_runddl(/some/rootlib, inc=LIBREF1 LIBREF2) * include only these libs;

    %mp_runddl(/some/rootlib, exc=LIBREF3) * same as above ;

  @brief Create a SAS Library
  @details Currently only supports BASE engine

    This macro is idempotent - if you run it twice (for the same libref or
    libname), it will only create one library.  There is a dependency on other
    macros in this library - they should be installed as a suite (see README).

  Usage:

    %mm_createlibrary(
       libname=My New Library
      ,libref=mynewlib
      ,libdesc=Super & <fine>
      ,engine=BASE
      ,tree=/User Folders/sasdemo
      ,servercontext=SASApp
      ,directory=/tmp/tests
      ,mDebug=1)

  <h4> Dependencies </h4>
  @li mf_verifymacvars.sas
  @li mm_createfolder.sas


  @param libname= Library name (as displayed to user, 256 chars). Duplicates
    are not created (case sensitive).
  @param libref= Library libref (8 chars).  Duplicate librefs are not created,
    HOWEVER- the check is not case sensitive - if *libref* exists, *LIBREF*
    will still be created.   Librefs created will always be uppercased.
  @param engine= Library engine (currently only BASE supported)
  @param tree= The metadata folder uri, or the metadata path, in which to
    create the library.
  @param servercontext= The SAS server against which the library is registered.
  @param IsPreassigned= set to 1 if the library should be pre-assigned.

  @param libdesc= Library description (optional)
  @param directory= Required for the BASE engine. The metadata directory objects
    are searched to find an existing one with a matching physical path.
    If more than one uri found with that path, then the first one will be used.
    If no URI is found, a new directory object will be created.  The physical
    path will also be created, if it doesn't exist.


  @param mDebug= set to 1 to show debug messages in the log
  @param frefin= fileref to use (enables change if there is a conflict).  The
    filerefs are left open, to enable inspection after running the
    macro (or importing into an xmlmap if needed).

  @brief Create a type 1 Stored Process (9.2 compatible)
  @details This macro creates a Type 1 stored process, and also the necessary
    PromptGroup / File / TextStore objects.  It requires the location (or uri)
    for the App Server / Directory / Folder (Tree) objects.
    To upgrade this macro to work with type 2 (which can embed SAS code
    and is compabitible with SAS from 9.3 onwards) then the UsageVersion should
    change to 2000000 and the TextStore object updated.  The ComputeServer
    reference will also be to ServerContext rather than LogicalServer.

    This macro is idempotent - if you run it twice, it will only create an STP
    once.

  usage (type 1 STP):

      %mm_createstp(stpname=MyNewSTP
        ,filename=mySpecialProgram.sas
        ,directory=SASEnvironment/SASCode/STPs
        ,tree=/User Folders/sasdemo
        ,outds=work.uris)

  If you wish to remove the new STP you can do so by running:

      data _null_;
        set work.uris;
        rc1 = METADATA_DELOBJ(texturi);
        rc2 = METADATA_DELOBJ(prompturi);
        rc3 = METADATA_DELOBJ(fileuri);
        rc4 = METADATA_DELOBJ(stpuri);
        putlog (_all_)(=);
      run;

  usage (type 2 STP):
      %mm_createstp(stpname=MyNewType2STP
        ,filename=mySpecialProgram.sas
        ,directory=SASEnvironment/SASCode/STPs

    create the STP.
  @param server= The server which will run the STP.  Server name or uri is fine.
  @param outds= The two level name of the output dataset.  Will contain all the
    meta uris. Defaults to work.mm_createstp.
  @param mDebug= set to 1 to show debug messages in the log
  @param stptype= Default is 1 (STP code saved on filesystem).  Set to 2 if
    source code is to be saved in metadata (9.3 and above feature).
  @param minify= set to YES to strip comments / blank lines etc
  @param frefin= fileref to use (enables change if there is a conflict).  The
    filerefs are left open, to enable inspection after running the
    macro (or importing into an xmlmap if needed).
  @param frefout= fileref to use (enables change if there is a conflict)
  @param repo= ServerContext is tied to a repo, if you are not using the
    foundation repo then select a different one here

  @returns outds  dataset containing the following columns:
   - stpuri
   - prompturi
   - fileuri
   - texturi

  @brief Create a Web Ready Stored Process
  @details This macro creates a Type 2 Stored Process with the macropeople
            mm_webout macro included as pre-code.
Usage:

    %* compile macros ;
    filename mc url "https://raw.githubusercontent.com/macropeople/macrocore/master/mc_all.sas";
    %inc mc;

    %* parmcards lets us write to a text file from open code ;
    filename ft15f001 temp;
    parmcards4;
        %* do some sas, any inputs are now already WORK tables;
        data example1 example2;
          set sashelp.class;
        run;
        %* send data back;
        %webout(OPEN)
        %webout(ARR,example1) * Array format, fast, suitable for large tables ;
        %webout(OBJ,example2) * Object format, easier to work with ;
        %webout(CLOSE)
    ;;;;

  <h4> Dependencies </h4>
  @li mm_createstp.sas
  @li mf_getuser.sas
  @li mm_createfolder.sas
  @li mm_deletestp.sas

  @param path= The full path (in SAS Metadata) where the service will be created
  @param name= Stored Process name.  Avoid spaces - testing has shown that
    the check to avoid creating multiple STPs in the same folder with the same
    name does not work when the name contains spaces.
  @param desc= The description of the service (optional)
  @param precode= Space separated list of filerefs, pointing to the code that
    needs to be attached to the beginning of the service (optional)
  @param code= Space seperated fileref(s) of the actual code to be added
  @param server= The server which will run the STP.  Server name or uri is fine.
  @param mDebug= set to 1 to show debug messages in the log
  @param replace= select YES to replace any existing service in that location
  @param adapter= the macro uses the sasjs adapter by default.  To use another
    adapter, add a (different) fileref here.

  @file mm_spkexport.sas
  @brief Creates an batch spk export command
  @details Creates a script that will export everything in a metadata folder to 
    a specified location.
    If you have XCMD enabled, then you can use mmx_spkexport (which performs
    the actual export)

    Note - the batch tools require a username and password.  For security,
    these are expected to have been provided in a protected directory.

  Usage:

      %* import the macros (or make them available some other way);
      filename mc url "https://raw.githubusercontent.com/macropeople/macrocore/master/mc_all.sas";
      %inc mc;

      %* create sample text file as input to the macro;
      filename tmp temp;
      data _null_;
        file tmp;
        put '%let mmxuser="sasdemo";';
        put '%let mmxpass="Mars321";';
      run;

      filename myref "%sysfunc(pathname(work))/mmxexport.sh";
      %mm_spkexport(metaloc=%str(/my/meta/loc)
          ,outref=myref
          ,secureref=tmp
          ,cmdoutloc=%str(/tmp)
      )

  Alternatively, call without inputs to create a function style output

      filename myref "/tmp/mmscript.sh";
      %mm_spkexport(metaloc=%str(/my/meta/loc)
           outref=myref
          ,cmdoutloc=%str(/tmp)
          ,cmdoutname=mmx
      )

  You can then navigate and execute as follows:

      cd /tmp
      ./mmscript.sh "myuser" "mypass"

  @file
  @brief Add or update an extension to an application component
  @details A SAS Application (SoftwareComponent) is a great place to store app
    specific parameters.  There are two main places those params can be stored:
    1) Configuration, and 2) Extensions.  The second location will enable end

    plugin in SMC.  This macro can be used after creating an application with
    the mm_createapplication.sas macro.  If a parameter with the same name
    exists, it is updated.  If it does not, it is created.

  @brief Send data to/from SAS Stored Processes
  @details This macro should be added to the start of each Stored Process,
  **immediately** followed by a call to:

        %mm_webout(FETCH)

    This will read all the input data and create same-named SAS datasets in the
    WORK library.  You can then insert your code, and send data back using the
    following syntax:

        data some datasets; * make some data ;
        retain some columns;
        run;

        %mm_webout(OPEN)
        %mm_webout(ARR,some)  * Array format, fast, suitable for large tables ;
        %mm_webout(OBJ,datasets) * Object format, easier to work with ;

    Finally, wrap everything up send some helpful system variables too

        %mm_webout(CLOSE)


  @param action Either FETCH, OPEN, ARR, OBJ or CLOSE
  @param ds The dataset to send back to the frontend
  @param dslabel= value to use instead of the real name for sending to JSON

  @file mv_tokenauth.sas
  @brief Get initial Refresh and Access Tokens
  @details Before a Refresh Token can be obtained, the client must be
    registered by an administrator.  This can be done using the
    `mv_registerclient` macro, after which the user must visit a URL to get an
    additional code (if using oauth).

    That code (or username / password) is used here to get the Refresh Token
    (and an initial Access Token).  THIS MACRO CAN ONLY BE USED ONCE - further
    access tokens can be obtained using the `mv_gettokenrefresh` macro.

    Access tokens expire frequently (every 10 hours or so) whilst refresh tokens
    expire periodically (every month or so).  This is all configurable.

  Usage:

      filename mc url "https://raw.githubusercontent.com/macropeople/macrocore/master/mc_all.sas";
      %inc mc;


      %mv_registerclient(outds=clientinfo)

  @brief Send data to/from the SAS Viya Job Execution Service
  @details This macro should be added to the start of each Job Execution
  Service, **immediately** followed by a call to:

        %mv_webout(FETCH)

    This will read all the input data and create same-named SAS datasets in the
    WORK library.  You can then insert your code, and send data back using the
    following syntax:

        data some datasets; * make some data ;
        retain some columns;
        run;

        %mv_webout(OPEN)
        %mv_webout(ARR,some)  * Array format, fast, suitable for large tables ;
        %mv_webout(OBJ,datasets) * Object format, easier to work with ;
        %mv_webout(CLOSE)


  @param action Either OPEN, ARR, OBJ or CLOSE
  @param ds The dataset to send back to the frontend
  @param _webout= fileref for returning the json
  @param fref= temp fref
  @param dslabel= value to use instead of the real name for sending to JSON
  @param fmt= change to N to strip formats from output
