jqr_core function

JQ Streaming API

Low level JQ API. First create a program using a query and flags and then feed pieces of data.

jqr_new(query, flags = jq_flags())

jqr_feed(jqr_program, json, unlist = TRUE, finalize = FALSE)

Arguments

• query: string with a valid jq program
• flags: See jq_flags
• jqr_program: object returned by [jqr_new]
• json: character vector with json data. If the JSON object is incomplete, you must set finalize to FALSE otherwise you get an error.
• unlist: if TRUE returns a single character vector with all output for each each string in json input
• finalize: completes the parsing and verifies that the JSON string is valid. Set this to TRUE when feeding the final piece of data.

Examples

program <- jqr_new(".[]")
jqr_feed(program, c("[123, 456]", "[77, 88, 99]"))
jqr_feed(program, c("[41, 234]"))
jqr_feed(program, "", finalize = TRUE)
