However, being a command-line tool like sed, the +feedback for writing queries and seeing their results is a discrete +process and not live. + +When working with Emacs, we are used to good auto-completion and live +feedback. Formerly, this was mostly done with static input, but with +modern completion frameworks like Ivy and Counsel, this can be done +with dynamic inputs, as well. + +counsel-jq is a package with which you can quickly test queries and +traverse a complex JSON structure whilst having live feedback. Just +call `M-x counsel-jq` in a buffer containing JSON, then start writing +your `jq` query string and see the output appear live in the message +area. Whenever you're happy, hit `RET` and the results will be +displayed to you in the buffer `*jq-json*`. + +In this lightning talk, I'll give a quick overview on how to use +counsel-jq and how to build similar completion functionality. + |
