Re: iSeries based JSON "Pretty" formatter?

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

Hello,

Typically, if a user is going to display JSON in a pretty format, you 
can send it to them in any format, and they'll use a tool that displays 
it nicely for them.   So, no special processing is needed on your end.

If your requirements are different and its important to do this in 
program code...  this is unusual, but should be possible with YAJL.   
Open an existing JSON document into a tree using yajl_stmf_load_tree() 
(or one of the other yajl tools that loads a tree) and then use YAJL's 
generator to create output.   There's a routine called YAJL_genFromNode 
that you can call, pass a node (such as the document node returned by 
yajl_stmf_load_tree) and it will add that entire tree to the generated 
JSON.   If you've configured the JSON generate to generate in "pretty" 
format, the yajl_genFromNode will essentially copy the structure, but 
the output will be "pretty".

Good Luck
