JSON::Tight
A JSON pretty-printer with a width budget. Each collection is rendered on a single line when it fits, in aligned columns when its elements are all individually short, or expanded one element per line when nothing tighter fits. Numbers are right-aligned within their column.
JSON::Tight.generate(JSON.parse(%([1,2,3]))) # => "[ 1, 2, 3 ]\n"
JSON::Tight.generate({"a" => 1, "b" => [2, 3]})
JSON::Tight.generate(json: %({"a":1}), width: 40)The width budget applies to content only; leading indentation is not counted.
