I've updated the JSON utilities first described here. Changes:
So, what else could I do to make these useful? One option would be to allow a wider range of XPath selectors - currently only the child axis is supported - but I'm not sure how to do that and preserve the structure of the input, which is essential for the kind of thing I use
jdoutputs JSON, as it should really have done all along. It's now an even thinner wrapper around Makamaka Hannyaharamitu's excellent JSON module :-)jfnow has a-poption that pretty-prints its output directly.jfcan now handle several field specifiers at once, and preserves enough of the structure of the input to contain them all. Here's an example:$ curl -s -upozorvlak:<my password here> http://api.twitter.com/1/statuses/mentions.json \ | jf -p user/name user/screen_name text [ { "text" : "@pozorvlak I have to admit that if you have polymorphism then things like +. are particularly pointless.", "user" : { "name" : "Christopher Yocum", "screen_name" : "cyocum" } }, { "text" : "@pozorvlak Huh, I still like the safety that static typing gives you.", "user" : { "name" : "Christopher Yocum", "screen_name" : "cyocum" } } ... etc ... ]The XPathy syntax is due to Leon Timmermans.

jf for. I could certainly document the programs better. For now, though, I think I'll email Makamaka and ask if he'd be interested in including jf in the JSON.pm distribution.Tags:
