jq is a nice tool. oj is similar in many ways but different in others. jq has it's own proprietary query language while oj uses JSON path. The output options are also different with some overlap. Maybe jq will get a pretty output option after reading the article. :-)

In my experience jq already does pretty the output. Maybe I'm missing something in your comment.

"pretty output" meaning the one called "Human Style" in the article, where multiple array elements or key-value pairs are compacted onto 1 line, IF they fit into the specified line length.

jq output is "pretty" by default, just without the ability to customize the prettification (as far as I know). If you want non-"pretty" output you need to add the `-c/--compact` option

jq output is also colorized on a tty output. This can be forced when piping to a pager e.g. `<json-producing command> | jq -S -C . | less -R`

I found JSON path to be so, so weak and limiting. Missing powerful axis traversals like xpath has, and also has very confusing semantics (the filter condition also changes the output???).

I hoped to find jq as a gem/module/library but I was disappointed. After days of searching and trying different things, I honestly could not find any powerful library or API for traversing and searching JSON.

JMESPath (https://jmespath.org/) is closer to XPath, with the support for the axis traversal, filtering expressions and embeddable libraries in most mainstream programming languages. It also comes with jq-styled processing pipelines; the syntax is the same that AWS use to query AWS resources.

What does "proprietary query language" mean in this context? jq is open source, right?
