/**
  @file
  @brief abort gracefully according to context
  @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 STP sessions

  The method used varies according to the context.  Important points:

  @li should not use endsas or abort cancel in 9.4m3 environments as this can
    cause hung multibridge sessions and result in a frozen STP server
  @li should not use endsas in viya 3.5 as this destroys the session and cannot
    fetch results (although both mv_getjoblog.sas and the @sasjs/adapter will
    recognise this and fetch the log of the parent session instead)
  @li STP environments must finish cleanly to avoid the log being sent to
    _webout.  To assist with this, we also run stpsrvset('program error', 0)
    and set SYSCC=0.  For 9.4m3 we take a unique approach - we open a macro
    but don't close it!  This provides a graceful abort, EXCEPT when called
    called within a %include within a macro (and that macro contains additional
    logic).  See mp_abort.test.nofix.sas for the example case.
    If you know of another way to gracefully abort a 9.4m3 STP session, we'd
    love to hear about it!

  to process using SAS defaults.
  This macro converts any csv to follow the convention of a windows excel file,
  applying CRLF line endings and converting embedded cr and crlf to lf.

  @file
  @brief Checks an input filter table for validity
  @details Performs checks on the input table to ensure it arrives in the
  correct format.  This is necessary to prevent code injection.  Will update
  SYSCC to 1008 if bad records are found, and call mp_abort.sas for a
  graceful service exit (configurable).

  Used for dynamic filtering in [Data Controller for SAS&reg;](https://datacontroller.io).

  Usage:

      %mp_filtercheck(work.filter,targetds=sashelp.class,outds=work.badrecords)

  The input table should have the following format:

  |GROUP_LOGIC:$3|SUBGROUP_LOGIC:$3|SUBGROUP_ID:8.|VARIABLE_NM:$32|OPERATOR_NM:$10|RAW_VALUE:$4000|
  |---|---|---|---|---|---|
  |AND|AND|1|AGE|=|12|
  |AND|AND|1|SEX|<=|'M'|
  |AND|OR|2|Name|NOT IN|('Jane','Alfred')|
  |AND|OR|2|Weight|>=|7|

  Rules applied:

  @li GROUP_LOGIC - only AND/OR
  @li SUBGROUP_LOGIC - only AND/OR
  @li SUBGROUP_ID - only integers
  @li VARIABLE_NM - must be in the target table
  @li OPERATOR_NM - only =/>/</<=/>=/BETWEEN/IN/NOT IN/NE/CONTAINS
  @li RAW_VALUE - no unquoted values except integers, commas and spaces.

  @returns The &outds table containing any bad rows, plus a REASON_CD column.

  @param [in] inds The table to be checked, with the format above
  @param [in] targetds= The target dataset against which to verify VARIABLE_NM.
    This must be available (ie, the library must be assigned).
  @param [out] abort= (YES) If YES will call mp_abort.sas on any exceptions
  @param [out] outds= The output table, which is a copy of the &inds. table
    plus a REASON_CD column, containing only bad records.  If bad records found,
    the SYSCC value will be set to 1008 (general data problem).  Downstream
    processes should check this table (and return code) before continuing.

  @file
  @brief Generates a filter clause from an input table, to a fileref
  @details Uses the input table to generate an output filter clause.
  This feature is used to create dynamic dropdowns in [Data Controller for SAS&reg](
  https://datacontroller.io). The input table should be in the format below:

  |GROUP_LOGIC:$3|SUBGROUP_LOGIC:$3|SUBGROUP_ID:8.|VARIABLE_NM:$32|OPERATOR_NM:$10|RAW_VALUE:$4000|
  |---|---|---|---|---|---|
  |AND|AND|1|AGE|=|12|
  |AND|AND|1|SEX|<=|'M'|
  |AND|OR|2|Name|NOT IN|('Jane','Alfred')|
  |AND|OR|2|Weight|>=|7|

  Note - if the above table is received from an external client, the values
  should first be validated using the mp_filtercheck.sas macro to avoid risk
  of SQL injection.

  To generate the filter, run the following code:

      data work.filtertable;
        infile datalines4 dsd;
        input GROUP_LOGIC:$3. SUBGROUP_LOGIC:$3. SUBGROUP_ID:8. VARIABLE_NM:$32.
          OPERATOR_NM:$10. RAW_VALUE:$4000.;
      datalines4;
      AND,AND,1,AGE,=,12
      AND,AND,1,SEX,<=,"'M'"
      AND,OR,2,Name,NOT IN,"('Jane','Alfred')"
      AND,OR,2,Weight,>=,7
      ;;;;
      run;

      %mp_filtergenerate(work.filtertable,outref=myfilter)

      data _null_;
        infile myfilter;
        input;
        put _infile_;
      run;

  Will write the following query to the log:

  > (
  >     AGE = 12
  >   AND
  >     SEX <= 'M'
  > ) AND (
  >     Name NOT IN ('Jane','Alfred')
  >   OR
  >     Weight >= 7
  > )

  @param [in] inds The input table with query values
  @param [out] outref= The output fileref to contain the filter clause.  Will
    be created (or replaced).

  @details Runs a generated filter in proc sql with the validate option.
  Used in mp_filtercheck.sas in an fcmp container.

  Built to support dynamic filtering in
  [Data Controller for SAS&reg;](https://datacontroller.io).

  Usage:

      data work.filtertable;
        infile datalines4 dsd;
        input GROUP_LOGIC:$3. SUBGROUP_LOGIC:$3. SUBGROUP_ID:8. VARIABLE_NM:$32.
          OPERATOR_NM:$10. RAW_VALUE:$4000.;
      datalines4;
      AND,AND,1,AGE,=,12
      AND,AND,1,SEX,<=,"'M'"
      AND,OR,2,Name,NOT IN,"('Jane','Alfred')"
      AND,OR,2,Weight,>=,7
      ;;;;
      run;

      %mp_filtergenerate(work.filtertable,outref=myfilter)

      %mp_filtervalidate(myfilter,sashelp.class)


  @returns The SYSCC value will be 1008 if there are validation issues.

  @param [in] inref The input fileref to validate (generated by
    mp_filtergenerate.sas)
  @param [in] targetds The target dataset against which to verify the query
  @param [out] abort= (YES) If YES will call mp_abort.sas on any exceptions
  @param [out] outds= (work.mp_filtervalidate) Output dataset containing the
  error / warning message, if one exists.  If this table contains any rows,
  there are problems!

  @brief Extract DBML from SAS Libraries
  @details DBML is an open source markup format to represent databases.
  More details: https://www.dbml.org/home/

  Usage:


      %mp_getdbml(liblist=SASHELP WORK,outref=mydbml,showlog=YES)

  Take the log output and paste it into the renderer at https://dbdiagram.io
  to view your data model diagram.  The code takes a "best guess" at
  the one to one and one to many relationships (based on constraints
  and indexes, and assuming that the column names would match).

  You may need to adjust the rendered DBML to suit your needs.

  @file mp_getmaxvarlengths.sas
  @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:

  - NAME    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_guesspk.sas
  @brief Guess the primary key of a table
  @details Tries to guess the primary key of a table based on the following logic:

      * Columns with nulls are ignored
      * Return only column combinations that provide unique results
      * Start from one column, then move out to include composite keys of 2 to 6 columns

  The library of the target should be assigned before using this macro.

  Usage:

      filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;
      %mp_guesspk(sashelp.class,outds=classpks)

  @param baseds The dataset to analyse
  @param outds= The output dataset to contain the possible PKs
  @param max_guesses= The total number of possible primary keys to generate.  A
    table is likely to have multiple unlikely PKs, so no need to list them all. Default=3.
  @param min_rows= The minimum number of rows a table should have in order to try
    and guess the PK.  Default=5.

  > ERROR: Some code points did not transcode.

  > 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;

        %mp_jsonout(OPEN,jref=tmp)
        %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 the
  [sasjs adapter](https://github.com/sasjs/adapter).
  For more information see https://sasjs.io

  @param action Valid values:
    @li OPEN - opens the JSON
    @li OBJ - sends a table with each row as an object
    @li ARR - sends a table with each row in an array
    @li 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, valid options are:
    @li PROCJSON (default)
    @li DATASTEP (more reliable when data has non standard characters)

  @param dbg= DEPRECATED - was used to conditionally add PRETTY to
    proc json but this can cause line truncation in large files.

  This structure is also used by the Macro Core library for documenting input/

  We take the standard definition one step further by embedding the informat

      |---|---|---|
      |some text|42|01JAN1960|

  @file mp_runddl.sas
  @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 ;


  @param path location of the DDL folder structure
  @param inc= list of librefs to include
  @param exc= list of librefs to exclude (takes precedence over inc=)

  @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>

        ,tree=/User Folders/sasdemo

        ,directory=/tmp/tests
        ,mDebug=1)

  <h4> SAS Macros </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

  @file
  @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
        ,tree=/User Folders/sasdemo
        ,Server=SASApp
        ,stptype=2)

  @li mf_verifymacvars.sas
  @li mm_getdirectories.sas
  @li mm_updatestpsourcecode.sas
  @li mp_dropmembers.sas
  @li mm_getservercontexts.sas

  @param stpname= 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 stpdesc= Stored Process description (optional)
  @param filename= the name of the .sas program to run
  @param directory= The directory uri, or the actual path to the sas program
    (no trailing slash).  If more than uri is found with that path, then the
    first one will be used.
  @param tree= The metadata folder uri, or the metadata path, in which to
    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

  @file
  @brief Compares the metadata of a library with the physical tables
  @details Creates a series of output tables that show the differences between
  metadata and physical tables.
  Each output can be created with an optional prefix.

  Credit - Paul Homes
  https://platformadmin.com/blogs/paul/2012/11/sas-proc-metalib-ods-output

  Usage:

      %* create (and assign) a library for testing purposes ;
      %mm_createlibrary(
        libname=My Temp Library,
        libref=XXTEMPXX,
        tree=/User Folders/&sysuserid,
        directory=%sysfunc(pathname(work))
      )

      %* create some tables;
      data work.table1 table2 table3;
        a=1;b='two';c=3;
      run;

      %* register the tables;
      proc metalib;
        omr=(library="My Temp Library");
        report(type=detail);
        update_rule (delete);
      run;

      %* modify the tables;
      proc sql;
      drop table table3;
      alter table table2 drop c;
      alter table table2 add d num;

      %* run the macro;
      %mm_getlibmetadiffs(libname=My Temp Library)

      %* delete the library ;
      %mm_deletelibrary(name=My Temp Library)

  The program will create four output tables, with the following structure (and
  example data):

  #### &prefix.added
  |name:$32.|metaID:$17.|SAStabName:$32.|
  |---|---|---|
  | | |DATA1|

  #### &prefix.deleted
  |name:$32.|metaID:$17.|SAStabName:$32.|
  |---|---|---|
  |TABLE3|A5XLSNXI.BK0001HO|TABLE3|

  #### &prefix.updated
  |tabName:$32.|tabMetaID:$17.|SAStabName:$32.|metaName:$32.|metaID:$17.|sasname:$32.|metaType:$16.|change:$64.|
  |---|---|---|---|---|---|---|---|
  |TABLE2|A5XLSNXI.BK0001HN|TABLE2|c|A5XLSNXI.BM000MA9|c|Column|Deleted|
  | | | |d| |d|Column|Added|

  #### &prefix.meta
  |Label1:$28.|cValue1:$1.|nValue1:D12.3|
  |---|---|---|
  |Total tables analyzed|4|4|
  |Tables to be Updated|1|1|
  |Tables to be Deleted|1|1|
  |Tables to be Added|1|1|
  |Tables matching data source|1|1|
  |Tables not processed|0|0|

  If you are interested in more functionality like this (checking the health of
  SAS metadata and your SAS 9 environment) then do contact [Allan Bowe](
  https://www.linkedin.com/in/allanbowe) for details of our SAS 9 Health Check
  service.

  Our system scan will perform hundreds of checks to identify common issues,
  such as dangling metadata, embedded passwords, security issues and more.

  @param [in] libname= the metadata name of the library to be compared
  @param [out] outlib=(work) The library in which to store the output tables.
  @param [out] prefix=(metadiff) The prefix for the four tables created.

  @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/sasjs/core/main/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
  @param fmt=(Y) Set to N to send back unformatted values
  @param fref=(_webout) The fileref to which to write the JSON

/**
  @file
  @brief Extract the log from a completed SAS Viya Job
  @details Extracts log from a Viya job and writes it out to a fileref.

  To query the job, you need the URI.  Sample code for achieving this
  is provided below.

  ## Example

      %* First, compile the macros;
      filename mc url
        "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

      %* Next, create a job (in this case, a web service);
      filename ft15f001 temp;
      parmcards4;
        data ;
          rand=ranuni(0)*1000;
          do x=1 to rand;
            y=rand*4;
            output;
          end;
        run;
        proc sort data=&syslast
          by descending y;
        run;
      ;;;;
      %mv_createwebservice(path=/Public/temp,name=demo)

      %* Execute it;
      %mv_jobexecute(path=/Public/temp
        ,name=demo
        ,outds=work.info
      )

      %* Wait for it to finish;
      data work.info;
        set work.info;
        where method='GET' and rel='state';
      run;
      %mv_jobwaitfor(ALL,inds=work.info,outds=work.jobstates)

      %* and grab the uri;
      data _null_;
        set work.jobstates;
        call symputx('uri',uri);
      run;

      %* Finally, fetch the log;
      %mv_getjoblog(uri=&uri,outref=mylog)

  This macro is used by the mv_jobwaitfor.sas macro, which is generally a more
  convenient way to wait for the job to finish before fetching the log.

  If the remote session calls `endsas` then it is not possible to get the log
  from the provided uri, and so the log from the parent session is fetched
  instead.  This happens for a 400 response, eg below:

      ErrorResponse[version=2,status=400,err=5113,id=,message=The session
      requested is currently in a failed or stopped state.,detail=[path:
      /compute/sessions/LONGURI-ses0006/jobs/LONGURI/log/content, traceId: 63
      51aa617d01fd2b],remediation=Correct the errors in the session request,
      and create a new session.,targetUri=<null>,errors=[],links=[]]

  @param [in] access_token_var= The global macro variable to contain the access
    token
  @param [in] mdebug= set to 1 to enable DEBUG messages
  @param [in] grant_type= valid values:
    @li password
    @li authorization_code
    @li detect - will check if access_token exists, if not will use sas_services
      if a SASStudioV session else authorization_code.  Default option.
    @li sas_services - will use oauth_bearer=sas_services.
  @param [in] uri= The uri of the running job for which to fetch the status,
    in the format `/jobExecution/jobs/$UUID` (unquoted).
  @param [out] outref= The output fileref to which to APPEND the log (is always
  appended).

/**
  @file
  @brief Extract the result from a completed SAS Viya Job
  @details Extracts result from a Viya job and writes it out to a fileref
  and/or a JSON-engine library.

  To query the job, you need the URI.  Sample code for achieving this
  is provided below.

  ## Example

  First, compile the macros:

      filename mc url
        "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

  Next, create a job (in this case, a web service):

      filename ft15f001 temp;
      parmcards4;
        data test;
          rand=ranuni(0)*1000;
          do x=1 to rand;
            y=rand*4;
            output;
          end;
        run;
        proc sort data=&syslast
          by descending y;
        run;
        %webout(OPEN)
        %webout(OBJ, test)
        %webout(CLOSE)
      ;;;;
      %mv_createwebservice(path=/Public/temp,name=demo)

  Execute it:

      %mv_jobexecute(path=/Public/temp
        ,name=demo
        ,outds=work.info
      )

  Wait for it to finish, and grab the uri:

      data _null_;
        set work.info;
        if method='GET' and rel='self';
        call symputx('uri',uri);
      run;

  Finally, fetch the result (In this case, WEBOUT):

      %mv_getjobresult(uri=&uri,result=WEBOUT_JSON,outref=myweb,outlib=myweblib)


  @param [in] access_token_var= The global macro variable containing the access
    token
  @param [in] mdebug= set to 1 to enable DEBUG messages
  @param [in] grant_type= valid values:
    @li password
    @li authorization_code
    @li detect - will check if access_token exists, if not will use sas_services
        if a SASStudioV session else authorization_code.  Default option.
    @li sas_services - will use oauth_bearer=sas_services.
  @param [in] uri= The uri of the running job for which to fetch the status,
    in the format `/jobExecution/jobs/$UUID` (unquoted).

  @param [out] result= (WEBOUT_JSON) The result type to capture.  Resolves
  to "_[column name]" from the results table when parsed with the JSON libname
  engine.  Example values:
    @li WEBOUT_JSON
    @li WEBOUT_TXT

  @param [out] outref= (0) The output fileref to which to write the results
  @param [out] outlib= (0) The output library to which to assign the results
    (assumes the data is in JSON format)

/**
  @file
  @brief Extract the status from a running SAS Viya job
  @details Extracts the status from a running job and appends it to an output
  dataset with the following structure:

      | uri                                                           | state   | timestamp          |
      |---------------------------------------------------------------|---------|--------------------|
      | /jobExecution/jobs/5cebd840-2063-42c1-be0c-421ec3e1c175/state | running | 15JAN2021:12:35:08 |

  To query the running job, you need the URI.  Sample code for achieving this
  is provided below.

  ## Example

  First, compile the macros:

      filename mc url "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

  Next, create a long running job (in this case, a web service):

      filename ft15f001 temp;
      parmcards4;
        data ;
          rand=ranuni(0)*1000;
          do x=1 to rand;
            y=rand*4;
            output;
          end;
        run;
        data _null_;
          call sleep(5,1);
        run;
      ;;;;
      %mv_createwebservice(path=/Public/temp,name=demo)

  Execute it, grab the uri, and finally, check the job status:

      %mv_jobexecute(path=/Public/temp
        ,name=demo
        ,outds=work.info
      )

      data _null_;
        set work.info;
        if method='GET' and rel='state';
        call symputx('uri',uri);
      run;

      %mv_getjobstate(uri=&uri,outds=results)

  You can run this macro as part of a loop to await the final 'completed' status.
  The full list of status values is:

  @li idle
  @li pending
  @li running
  @li canceled
  @li completed
  @li failed

  If you have one or more jobs that you'd like to wait for completion you can
  also use the [mv_jobwaitfor](/mv__jobwaitfor_8sas.html) macro.

  @param [in] access_token_var= The global macro variable to contain the access token
  @param [in] grant_type= valid values:
    @li password
    @li authorization_code
    @li detect - will check if access_token exists, if not will use sas_services if
        a SASStudioV session else authorization_code.  Default option.
    @li sas_services - will use oauth_bearer=sas_services.
  @param [in] uri= The uri of the running job for which to fetch the status,
    in the format `/jobExecution/jobs/$UUID/state` (unquoted).
  @param [out] outds= The output dataset in which to APPEND the status. Three
    fields are appended:  `CHECK_TM`, `URI` and `STATE`. If the dataset does not
    exist, it is created.

  @brief Executes a SAS Viya Job
  @details Triggers a SAS Viya Job, with optional URL parameters, using
  the JES web app.

  First, compile the macros:

      filename mc url
      "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

  Then, execute the job!

      %mv_jobexecute(path=/Public/folder
        ,name=somejob
      )

  Example with parameters:

      %mv_jobexecute(path=/Public/folder
        ,name=somejob
        ,paramstring=%str("macvarname":"macvarvalue","answer":42)
      )

  @param [in] access_token_var= The global macro variable to contain the access
    token
  @param [in] grant_type= valid values:
    @li password
    @li authorization_code
    @li detect - will check if access_token exists, if not will use sas_services
      if a SASStudioV session else authorization_code.  Default option.
    @li sas_services - will use oauth_bearer=sas_services

  @param [in] path= The SAS Drive path to the job being executed
  @param [in] name= The name of the job to execute
  @param [in] paramstring= A JSON fragment with name:value pairs, eg:
    `"name":"value"` or "name":"value","name2":42`.  This will need to be
    wrapped in `%str()`.

  @param [in] contextName= Context name with which to run the job.
    Default = `SAS Job Execution compute context`
  @param [in] mdebug= set to 1 to enable DEBUG messages
  @param [out] outds= (work.mv_jobexecute) The output dataset containing links

  @file
  @brief Execute a series of job flows
  @details Very (very) simple flow manager.  Jobs execute in sequential waves,
  all previous waves must finish successfully.

  The input table is formed as per below.  Each observation represents one job.
  Each variable is converted into a macro variable with the same name.

  ## Input table (minimum variables needed)

  @li _PROGRAM - Provides the path to the job itself
  @li FLOW_ID - Numeric value, provides sequential ordering capability. Is
    optional, will default to 0 if not provided.
  @li _CONTEXTNAME - Dictates which context should be used to run the job. If
    blank, or not provided, will default to `SAS Job Execution compute context`.

  Any additional variables provided in this table are converted into macro
  variables and passed into the relevant job.

  |_PROGRAM| FLOW_ID (optional)| _CONTEXTNAME (optional) |
  |---|---|---|
  |/Public/jobs/somejob1|0|SAS Job Execution compute context|
  |/Public/jobs/somejob2|0|SAS Job Execution compute context|

  ## Output table (minimum variables produced)

  @li _PROGRAM - the SAS Drive path of the job
  @li URI - the URI of the executed job
  @li STATE - the completed state of the job
  @li TIMESTAMP - the datetime that the job completed
  @li JOBPARAMS - the parameters that were passed to the job
  @li FLOW_ID - the id of the flow in which the job was executed

  ![https://i.imgur.com/nZE9PvT.png](https://i.imgur.com/nZE9PvT.png)

  To avoid hammering the box with many hits in rapid succession, a one
  second pause is made between every request.


  ## Example

  First, compile the macros:

      filename mc url
      "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

  Next, create some jobs (in this case, as web services):

      filename ft15f001 temp;
      parmcards4;
        %put this is job: &_program;
        %put this was run in flow &flow_id;
        data ;
          rand=ranuni(0)*&macrovar1;
          do x=1 to rand;
            y=rand*&macrovar2;
            if y=100 then abort;
            output;
          end;
        run;
      ;;;;
      %mv_createwebservice(path=/Public/temp,name=demo1)
      %mv_createwebservice(path=/Public/temp,name=demo2)

  Prepare an input table with 60 executions:

      data work.inputjobs;
        _contextName='SAS Job Execution compute context';
        do flow_id=1 to 3;
          do i=1 to 20;
            _program='/Public/temp/demo1';
            macrovar1=10*i;
            macrovar2=4*i;
            output;
            i+1;
            _program='/Public/temp/demo2';
            macrovar1=40*i;
            macrovar2=44*i;
            output;
          end;
        end;
      run;

  Trigger the flow

      %mv_jobflow(inds=work.inputjobs
        ,maxconcurrency=4
        ,outds=work.results
        ,outref=myjoblog
      )

      data _null_;
        infile myjoblog;
        input; put _infile_;
      run;


  @param [in] access_token_var= The global macro variable to contain the
              access token
  @param [in] grant_type= valid values:
      @li password
      @li authorization_code
      @li detect - will check if access_token exists, if not will use
        sas_services if a SASStudioV session else authorization_code.  Default
        option.
      @li sas_services - will use oauth_bearer=sas_services
  @param [in] inds= The input dataset containing a list of jobs and parameters
  @param [in] maxconcurrency= The max number of parallel jobs to run. Default=8.
  @param [in] raise_err=0 Set to 1 to raise SYSCC when a job does not complete
            succcessfully
  @param [in] mdebug= set to 1 to enable DEBUG messages
  @param [out] outds= The output dataset containing the results
  @param [out] outref= The output fileref to which to append the log file(s).

  ## Example

  First, compile the macros:

      filename mc url
      "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

  Next, create a job (in this case, as a web service):

      filename ft15f001 temp;
      parmcards4;
        data ;
          rand=ranuni(0)*1000000;
          do x=1 to rand;
            y=rand*x;
            output;
          end;
        run;
      ;;;;
      %mv_createwebservice(path=/Public/temp,name=demo)

  Then, execute the job,multiple times, and wait for them all to finish:

      %mv_jobexecute(path=/Public/temp,name=demo,outds=work.ds1)
      %mv_jobexecute(path=/Public/temp,name=demo,outds=work.ds2)
      %mv_jobexecute(path=/Public/temp,name=demo,outds=work.ds3)
      %mv_jobexecute(path=/Public/temp,name=demo,outds=work.ds4)

      data work.jobs;
        set work.ds1 work.ds2 work.ds3 work.ds4;
        where method='GET' and rel='state';
      run;

      %mv_jobwaitfor(ALL,inds=work.jobs,outds=work.jobstates)

  Delete the job:

      %mv_deletejes(path=/Public/temp,name=demo)

  @file mv_registerclient.sas
  @brief Register Client and Secret (admin task)
  @details When building apps on SAS Viya, an client id and secret are sometimes
  required.  In order to generate them, filesystem access to the Consul Token
  is needed (it is not enough to be in the SASAdministrator group in SAS
  Environment Manager).

  If you are registering a lot of clients / secrets, you may find it more
  convenient to use the [Viya Token Generator]
  (https://sasjs.io/apps/#viya-client-token-generator) (a SASjs Web App to
  automate the generation of clients & secrets with various settings).

  For further information on clients / secrets, see;
  @li https://developer.sas.com/reference/auth/#register
  @li https://proc-x.com/2019/01/authentication-to-sas-viya-a-couple-of-approaches
  @li https://cli.sasjs.io/faq/#how-can-i-obtain-a-viya-client-and-secret

  The default viyaroot location is: `/opt/sas/viya/config`

  Usage:

      %* compile macros;
      filename mc url
        "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

      %* specific client with just openid scope;
      %mv_registerclient(client_id=YourClient
        ,client_secret=YourSecret
        ,scopes=openid
      )

      %* generate random client details with all scopes;
      %mv_registerclient(scopes=openid *)

      %* generate random client with 90/180 second access/refresh token expiry;
      %mv_registerclient(scopes=openid *
        ,access_token_validity=90
        ,refresh_token_validity=180
      )

  @param client_id= The client name.  Auto generated if blank.
  @param client_secret= Client secret.  Auto generated if client is blank.
  @param scopes=(openid) List of space-seperated unquoted scopes
  @param grant_type=(authorization_code|refresh_token) Valid values are
    "password" or "authorization_code" (unquoted)
  @param outds=(mv_registerclient) The dataset to contain the registered client
    id and secret
  @param access_token_validity=(DEFAULT) The duration of validity of the access
    token in seconds.  A value of DEFAULT will omit the entry (and use system
    default)
  @param refresh_token_validity=(DEFAULT)  The duration of validity of the
    refresh token in seconds.  A value of DEFAULT will omit the entry (and use
    system default)
  @param name= An optional, human readable name for the client
  @param required_user_groups= A list of group names. If a user does not belong
    to all the required groups, the user will not be authenticated and no tokens
    are issued to this client for that user. If this field is not specified,
    authentication and token issuance proceeds normally.
  @param autoapprove= During the auth step the user can choose which scope to
    apply.  Setting this to true will autoapprove all the client scopes.
  @param use_session= If true, access tokens issued to this client will be
    associated with an HTTP session and revoked upon logout or time-out.
  @param outjson= (_null_) A dataset containing the lines of JSON submitted.
    Useful for debugging.

  @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/sasjs/core/main/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=(_mvwtemp) Temp fileref to which to write the output
  @param dslabel= value to use instead of the real name for sending to JSON
  @param fmt=(Y) change to N to strip formats from output
  @param stream=(Y) Change to N if not streaming to _webout
