Since forever I have some variations of this:

function lq
    command jq . "$argv" -C | less -r
end

jless - A Command-Line JSON Viewer is this, but much better. Intuitive CLI viewer for json data, works seamlessly for large JSONs (which sometimes breaks my lq command, especially for large lines)

Now:

function lq
	echo "not again, Serhii!!! Use jless/jl"
    command jless -r -m line "$argv"
    # command jq . "$argv" -C | less -r
end

Jless

• m toggles the mode between line-mode (jq-like) and the (default) data mode
• -r does relative numbers! -N disables any line numbers
• h opens the help, the usual vim things do what I expect
  • H focuses the parent
• Yank/copy (all below can be pX to just print the value)
  • yy !!! copy the value, including "
  • yk copy the KEY under cursor
  • yp copy the path from root to current object

It does yaml as well!
