Re: iSeries based JSON "Pretty" formatter?

In regard to easy-to-read output format, I ended up producing a columnar
report for end users as opposed to just making the JSON "pretty".

Since JSON is oft-times hierarchical, I decided to show the "path" to each
node in a traditional directory format, along with the "node type",
"nesting level", and "value".

http://rd.radile.com/rdweb/info3/iui20/main.html

The report is generated by an RPG utility, which generates the report is as
follows:

docNode = jsnParseBuf(%addr(json_buffer):%len(json_buffer));

dow jsnForEach('/');
if jsnNodeInfo();
exsr output_report;
endif;
enddo;

jsnParseBuf() generates a node if you pass the address and length of a JSON
buffer.

jsnForEach() scans through each node in the tree.

jsnNodeInfo() transforms the JSON node into an RPG data structure.

output_report is an RPG subroutine that moves data structure subfields to
the "screen"

Output like JSONFormatter.org. Linking to a web site is a non-starter so
I'm searching for something iSeries based.

I have Scott's YAJL software installed and am using it with Data-Into.
However, I don't see an example in his thorough documentation to take any
JSON and pretty up the formatting for human viewing. There's a CLE pgm in
his YAJLLIB72 called JSON_Refmt but I can't figure it out.

Most RPGLE JSON open source I see is designed to create or disassemble
JSON - not display it.

Any suggestions?

TIA
