Pretty-printing JSON Lassi Kortela 22 Jan 2020 00:21 UTC

I also use "jq ." all the time, but keep wishing the original JSON was indented so I didn't have to do that :) Almost none of the JSON dumps are big enough that pretty-printing would cause a performance problem. > This would have to be an option to write-json, to prettyprint or not. I > hate options. :-) Several Schemes have a `pretty-print` or `pp` procedure for S-expressions. There could be a JSON equivalent `json-pretty-print`, for example. As Alan Perlis, Rich Hickey and many others have noted, having more procedures does not make the system more complex. It's only procedures that have to interact with each other that add complexity. The pretty printer can be separate from the writer (naturally the implementations would share many internals). But if `json-write` writes a condensed format like Scheme `write`, is it much different from a `json-write-line` that would write a JSON Lines compatible value? Would there in fact be any difference other than a final newline?
