From: Jeff Hostetler <jeffhost@xxxxxxxxxxxxx> This patch series adds a set of utility routines to compose data in JSON format into a "struct strbuf". The resulting string can then be output by commands wanting to support a JSON output format. This is a stand alone patch. Nothing currently uses these routines. I'm currently working on a series to log "telemetry" data (as we discussed briefly during Ævar's "Performance Misc" session [1] in Barcelona last week). And I want emit the data in JSON rather than a fixed column/field format. The JSON routines here are independent of that, so it made sense to submit the JSON part by itself. Back when we added porcelain=v2 format to status, we talked about adding a JSON format. I think the routines in this patch would let us easily do that, if someone were interested. (Extending status is not on my radar right now, however.) Documentation for the new API is given in json-writer.h at the bottom of the first patch. I wasn't sure how to unit test the API from a shell script, so I added a helper command that does most of the work in the second patch.
