  @brief Returns the appLoc from the _program variable
  @details When working with SASjs apps, web services / tests / jobs are always
  deployed to a root (app) location in the SAS logical folder tree.

  When building apps for use in other environments, you do not necessarily know
  where the backend services will be deployed.  Therefore a function like this
  is handy in order to dynamically figure out the appLoc, and enable other
  services to be connected by a relative reference.

  SASjs apps always have the same immediate substructure (one or more of the
  following):

  @li /data
  @li /jobs
  @li /services
  @li /tests/jobs
  @li /tests/services
  @li /tests/macros

  This function works by testing for the existence of any of the above in the
  automatic _program variable, and returning the part to the left of it.

  @file
  @brief Assigns and returns an unused fileref
  @details  Using the native approach for assigning filerefs fails as some
  procedures (such as proc http) do not recognise the temporary names (starting
  with a hash), returning a message such as:

  > ERROR 22-322: Expecting a name.

  This macro works by attempting a random fileref (with a prefix), seeing if it
  is already assigned, and if not - returning the fileref.

  If your process can accept filerefs with the hash (#) prefix, then set
  `prefix=0` to revert to the native approach - which is significantly faster
  when there are a lot of filerefs in a session.

  Use as follows:

      %let fileref1=%mf_getuniquefileref();
      %let fileref2=%mf_getuniquefileref(prefix=0);
      %put &fileref1 &fileref2;

  which returns filerefs similar to:

> _7432233 #LN00070

  @param [in] prefix= (_) first part of fileref. Remember that filerefs can only
    be 8 characters, so a 7 letter prefix would mean `maxtries` should be 10.
    if using zero (0) as the prefix, a native assignment is used.
  @param [in] maxtries= (1000) the last part of the libref. Must be an integer.

/**
  @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.  We take a unique "soft abort" approach - we open a macro
    but don't close it!  This works everywhere EXCEPT inside a \%include inside
    a macro.  For that, we recommend you use mp_include.sas to perform the
    include, and then call \%mp_abort(mode=INCLUDE) from the source program (ie,
    OUTSIDE of the top-parent macro).


  @param mac= to contain the name of the calling macro
  @param msg= message to be returned
  @param iftrue= supply a condition under which the macro should be executed.
  @param errds= (work.mp_abort_errds) There is no clean way to end a process
    within a %include called within a macro.  Furthermore, there is no way to
    test if a macro is called within a %include.  To handle this particular
    scenario, the %include should be switched for the mp_include.sas macro.
    This provides an indicator that we are running a macro within a \%include
    (`_SYSINCLUDEFILEDEVICE`) and allows us to provide a dataset with the abort
    values (msg, mac).
    We can then run an abort cancel FILE to stop the include running, and pass
    the dataset back to the calling program to run a regular \%mp_abort().
    The dataset will contain the following fields:
    @li iftrue (1=1)
    @li msg (the message)
    @li mac (the mac param)

  @param mode= (REGULAR) If mode=INCLUDE then the &errds dataset is checked for
    an abort status.
    Valid values:
    @li REGULAR (default)
    @li INCLUDE

  @details Used to import relevant columns from a large CSV using
  a dataset to provide the types and lengths.  Assumes that a header
  row is provided, and datarows start on line 2.  Extra columns in
  both the CSV and base dataset are ignored.

  Usage:

      filename mycsv temp;
      data _null_;
        file mycsv;
        put 'name,age,nickname';
        put 'John,48,Jonny';
        put 'Jennifer,23,Jen';
      run;

      %mp_csv2ds(inref=mycsv,outds=myds,baseds=sashelp.class)


  @param inref= fileref to the CSV
  @param outds= output ds (lib.ds format)
  @param view= Set to YES or NO to determine whether the output should be
    a view or not.  Default is NO (not a view).
  @param baseds= Template dataset on which to create the input statement.
    Is used to determine types, lengths, and any informats.

  @file

  If getattrs=YES then the doptname / foptname functions are used to scan all
  properties - any characters that are not valid in a SAS name (v7) are simply
  stripped, and the table is transposed so theat each property is a column
  and there is one file per row.  An attempt is made to get all properties
  whether a file or folder, but some files/folders cannot be accessed, and so
  not all properties can / will be populated.

  Credit for the rename approach:

  @warning In a Unix environment, the existence of a named pipe will cause this
  macro to hang.  Therefore this tool should be used with caution in a SAS 9 web
  application, as it can use up all available multibridge sessions if requests
  are resubmitted.
  If anyone finds a way to positively identify a named pipe using SAS (without
  X CMD) do please raise an issue!

  @param fref= Provide a DISK engine fileref as an alternative to PATH
  @param outds= the output dataset to create
  @param getattrs= YES/NO (default=NO).  Uses doptname and foptname to return

  @returns outds contains the following variables:

    - file_or_folder (file / folder)
    - filepath (path/to/file.name)
    - filename (just the file name)

    alternative encoding.  If the input dataset is empty, the cards file will
    still be created.

    Additional support to generate a random sample and max rows.

  Usage:

    - constraints / indexes etc

                  that is converted to a cards file.
  @param [in] tgt_ds= Table that the generated cards file would create.
    Optional - if omitted, will be same as BASE_DS.
  @param [out] cards_file= ("%sysfunc(pathname(work))/cardgen.sas") Location in
    which to write the (.sas) cards file
  @param [in] maxobs= (max) To limit output to the first <code>maxobs</code>
    observations, enter an integer here.
  @param [in] random_sample= (NO) Set to YES to generate a random sample of
    data.  Can be quite slow.
  @param [in] showlog= (YES) Whether to show generated cards file in the SAS
    log.  Valid values:
    @li YES
    @li NO
  @param [in] outencoding= Provide encoding value for file statement (eg utf-8)
  @param [in] append= (NO) If NO then will rebuild the cards file if it already

  @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.

  @brief Generates a filter clause from an input table, to a fileref

  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.

      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).

  Take the log output and paste it into the renderer at https://dbdiagram.io

  the one to one and one to many relationships (based on constraints

  @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
  @brief Performs a text substitution on a file
  @details Makes use of the GSUB function in LUA to perform a text substitution
  in a file - either in-place, or writing to a new location.  The benefit of
  using LUA is that the entire file can be loaded into a single variable,
  thereby side stepping the 32767 character limit in a data step.

  Usage:

      %let file=%sysfunc(pathname(work))/file.txt;
      %let str=replace/me;
      %let rep=with/this;
      data _null_;

      data _null_;
        infile "&file";
        input;
        list;
      run;

  @param file= (0) The file to perform the substitution on
  @param patternvar= A macro variable containing the Lua
    [pattern](https://www.lua.org/pil/20.2.html) to search for.  Due to the use
    of special (magic) characters in Lua patterns, it is safer to pass the NAME
    of the macro variable containing the string, rather than the value itself.
  @param replacevar= The name of the macro variable containing the replacement
    _string_.
  @param outfile= (0) The file to write the output to. If zero, then the file
    is overwritten in-place.

  @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.

  @file
  @brief Performs a wrapped \%include
  @details This macro wrapper is necessary if you need your included code to
  know that it is being \%included.

  If you are using %include in a regular program, you could make use of the
  following macro variables:

  @li SYSINCLUDEFILEDEVICE
  @li SYSINCLUDEFILEDIR
  @li SYSINCLUDEFILEFILEREF
  @li SYSINCLUDEFILENAME

  However these variables are NOT available inside a macro, as documented here:
https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/mcrolref/n1j5tcc0n2xczyn1kg1o0606gsv9.htm

  This macro can be used in place of the %include statement, and will insert
  the following (equivalent) global variables:

  @li _SYSINCLUDEFILEDEVICE
  @li _SYSINCLUDEFILEDIR
  @li _SYSINCLUDEFILEFILEREF
  @li _SYSINCLUDEFILENAME

  These can be used whenever testing _within a macro_.  Outside of the macro,
  the regular automatic variables will still be available (thanks to a
  concatenated file list in the include statement).

  Example usage:

      filename example temp;
      data _null_;
        file example;
        put '%macro test();';
        put '%put &=_SYSINCLUDEFILEFILEREF;';
        put '%put &=SYSINCLUDEFILEFILEREF;';
        put '%mend; %test()';
        put '%put &=SYSINCLUDEFILEFILEREF;';
      run;
      %mp_include(example)

  @param [in] fileref The fileref of the file to be included. Must be provided.
  @param [in] prefix= (_) The prefix to apply to the global variables.
  @param [in] opts= (SOURCE2) The options to apply to the %inc statement
  @param [in] errds= (work.mp_abort_errds) There is no clean way to end a
    process within a %include called within a macro.  Furthermore, there is no
    way to test if a macro is called within a %include.  To handle this
    particular scenario, the %mp_abort() macro will test for the existence of
    the `_SYSINCLUDEFILEDEVICE` variable and return the outputs (msg,mac) inside
    this dataset.
    It will then run an abort cancel FILE to stop the include running, and pass
    the dataset back.
    NOTE - it is NOT possible to read this dataset as part of _this_ macro -
    when running abort cancel FILE, ALL macros are closed, so instead it is
    necessary to invoke "%mp_abort(mode=INCLUDE)" OUTSIDE of any macro wrappers.

  > (ERR)OR: Some code points did not transcode.

  > An object or array close is not valid at this point in the JSON text.

  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.

  @brief Create a Markdown Table from a dataset
  @details A markdown table is a simple table representation for use in
  documents written in markdown format.

  An online generator is available here:
  https://www.tablesgenerator.com/markdown_tables

  This structure is also used by the Macro Core library for documenting input/
  output datasets, as well as the sasjs/cli tool for documenting inputs/outputs
  for web services.

  We take the standard definition one step further by embedding the informat
  in the table header row, like so:

      |var1:$32|var2:best.|var3:date9.|
      |---|---|---|
      |some text|42|01JAN1960|
      |blah|1|31DEC1999|

  @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 ;

  @file
  @brief Fix the `_WEBIN` variables provided to SAS web services
  @details When uploading files to SAS Stored Processes or Viya Jobs a number
  of global macro variables are automatically created - however there are some
  differences in behaviour both between SAS 9 and Viya, and also between a
  single file upload and a multi-file upload.

  This macro "straightens" up the global macro variables to make it easier /
  simpler to write code that works in both environments and with a variable
  number of file inputs.

  After running this macro, the following global variables will *always* exist:
  @li `_WEBIN_FILE_COUNT`
  @li `_WEBIN_FILENAME1`
  @li `_WEBIN_FILEREF1`
  @li `_WEBIN_NAME1`

  Usage:

    %mp_webin()

  This was created as a macro procedure (over a macro function) as it will also
  use the filename statement in Viya environments (where `_webin_fileuri` is
  provided).

  @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> 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
    macro (or importing into an xmlmap if needed).
  @param frefout= fileref to use (enables change if there is a conflict)

  @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

  @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

Usage:

    %* compile macros ;

    %inc mc;

    %* parmcards lets us write to a text file from open code ;

        run;
        %* send data back;
        %webout(OPEN)
        %webout(ARR,example1) * Array format, fast, suitable for large tables ;

  <h4> SAS Macros </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=(ft15f001) Space seperated fileref(s) of the actual code to be
    added
  @param server=(SASApp) The server which will run the STP.  Server name or uri
    is fine.
  @param mDebug=(0) set to 1 to show debug messages in the log
  @param replace=(YES) select NO to avoid replacing an existing service in that
    location
  @param adapter=(sasjs) the macro uses the sasjs adapter by default.  To use
    another adapter, add a (different) fileref here.

  @file
  @brief Compares the metadata of a library with the physical tables

  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;

      %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|

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

  @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
    users to modify parameters even if they don't have the Configuration Manager
    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.

  Usage:

    %mm_updateappextension(app=/my/metadata/path/myappname
      ,paramname=My Param
      ,paramvalue=My value
      ,paramdesc=some description)


  @param app= the BIP Tree folder path plus Application Name
  @param paramname= Parameter name
  @param paramvalue= Parameter value
  @param paramdesc= Parameter description

  @param frefin= change default inref if it clashes with an existing one
  @param frefout= change default outref if it clashes with an existing one
  @param mDebug= set to 1 to show debug messages in the log

  @param [in] path= The full path (on SAS Drive) where the service will be
    created
  @param [in] name= The name of the service
  @param [in] desc= The description of the service
  @param [in] precode= Space separated list of filerefs, pointing to the code
    that needs to be attached to the beginning of the service
  @param [in] code= Fileref(s) of the actual code to be added
  @param [in] access_token_var= The global macro variable to contain the access
    token
  @param [in] grant_type= valid values are "password" or "authorization_code"
    (unquoted). The default is authorization_code.
  @param [in] replace=(YES) Select NO to avoid replacing any existing service in
    that location
  @param [in] adapter= the macro uses the sasjs adapter by default.  To use
    another adapter, add a (different) fileref here.
  @param [in] contextname= Choose a specific context on which to run the Job.  Leave
    blank to use the default context.  From Viya 3.5 it is possible to configure
    a shared context - see
https://go.documentation.sas.com/?docsetId=calcontexts&docsetTarget=n1hjn8eobk5pyhn1wg3ja0drdl6h.htm&docsetVersion=3.5&locale=en
  @param [in] mdebug=(0) set to 1 to enable DEBUG messages

/**
  @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= (0) 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

        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,

/**
  @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 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

  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).

  _state_, as per the following table:

  | state     | Wait? | Notes|

  ## 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)

  @param [in] access_token_var= The global macro variable to contain the access
    token
  @param [in] grant_type= valid values:

      - password
      - authorization_code
      - detect - will check if access_token exists, if not will use sas_services
        if a SASStudioV session else authorization_code.  Default option.
      - sas_services - will use oauth_bearer=sas_services

  @param [in] action=Either ALL (to wait for every job) or ANY (if one job
    completes, processing will continue).  Default=ALL.
  @param [in] inds= The input dataset containing the list of job uris, in the
    following format:  `/jobExecution/jobs/&JOBID./state` and the corresponding
    job name.  The uri should be in a `uri` variable, and the job path/name
    should be in a `_program` variable.
  @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 list of states by job
    (default=work.mv_jobexecute)
  @param [out] outref= A fileref to which the spawned job logs should be
    appended.

  @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)

      %mv_tokenauth(inds=clientinfo,code=LD39EpalOf)

/**
  @file
  @brief Provides a replacement for the stpsrv_header function
  @details The stpsrv_header is normally a built-in function, used to set the
  headers for SAS 9 Stored Processes as documented here:
  https://go.documentation.sas.com/doc/en/itechcdc/9.4/stpug/srvhead.htm

  The purpose of this custom function is to provide a replacement when running
  similar code as a web service against
  [sasjs/server](https://github.com/sasjs/server).  It operates by creating a
  text file with the headers.  The location of this text file is determined by
  a macro variable (`sasjs_stpsrv_header_loc`) which needs to be injected into
  each service by the calling process, eg:

      %let sasjs_stpsrv_header_loc = C:/temp/some_uuid/stpsrv_header.txt;

  Note - the function works by appending headers to the file.  If multiple same-
  named headers are provided, they will all be appended - the calling process
  needs to pick up the last one.  This will mean removing the attribute if the
  final record has an empty value.

  The function takes the following (positional) parameters:

  | PARAMETER | DESCRIPTION |
  |------------|-------------|
  | name $  | name of the header attribute to create|
  | value  $  | value of the header attribute|

  It returns 0 if successful, or -1 if an error occured.

  Usage:

      %let sasjs_stpsrv_header_loc=%sysfunc(pathname(work))/stpsrv_header.txt;

      %mcf_stpsrv_header(wrap=YES, insert_cmplib=YES)

      data _null_;
        rc=stpsrv_header('Content-type','application/text');
        rc=stpsrv_header('Content-disposition',"attachment; filename=file.txt");
      run;

      data _null_;
        infile "&sasjs_stpsrv_header_loc";
        input;
        putlog _infile_;
      run;


  @param [out] wrap= (NO) Choose YES to add the proc fcmp wrapper.
  @param [out] insert_cmplib= (NO) Choose YES to insert the package into the
