Jless, a command-line JSON viewer▲344
Hey, Hacker News! Today I'm proud to release jless, a command-line JSON viewer. jless provides a JSON viewing experience similar to what you see in a browser's network tab in the developer console, but from the comfort of your terminal, with a whole suite of vim-inspired key bindings to easily manipulate your view of the data and full-text regex search. I'm sure many of you have some piped together some combination of cat, jq and less before; hopefully jless can replace that usage (hence the name).

JSON Query▲154
I'm working on a tool that will probably involve querying JSON documents and I'm asking myself how to expose that functionality to my users.
