Description

jless currently returns 0 (success) as an exit code, even if the command failed (e.g. if the input wasn't valid JSON). To reproduce:

jless - <<<"This is no JSON"; echo $?

will result the following output:

Unable to parse input: "Parse error"
0

Impact / use-case

Having a non-zero exit code increases interoperability and allows for fallbacks in scripts, e.g. jless "$@" || less "$@"
