...I chose the name because I had moved to Montreal so I remembered Philly fondly. Also, there isn't a better way to describe objects encoded in JSON than "things". Finally, we get a catchy slogan. Jawn was designed to parse JSON into an AST as quickly as possible. Currently, Jawn is competitive with the fastest Java JSON libraries (GSON and Jackson) and in the author's benchmarks, it often wins. It seems to be faster than any other Scala parser that exists (as of July 2014).

query-json is a faster, simpler, and more portable implementation of the jq language in Reason distributed as a dependency-free binary thanks to the OCaml compiler, and distributed to the web with js_of_ocaml. query-json allows you to write small programs to operate on top of json files with a concise syntax.

A final implementation of JSONPath for Python that aims to be standard compliant, including arithmetic and binary comparison operators, as defined in the original JSONPath proposal. This package merges both jsonpath-rw and jsonpath-rw-ext and provides several AST API enhancements, such as the ability to update or remove nodes in the tree. This library provides a robust and significantly extended implementation of JSONPath for Python. It is tested with CPython 3.7 and higher. This library differs from other JSONPath implementations in that it is a full language implementation, meaning the JSONPath expressions are first-class objects, easy to analyze, transform, parse, print, and extend.

...As a consequence, the compiler will automatically check for null references in compile time, helping prevent the dreadful billion-dollar mistake. Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection, to types inspection and running arbitrary external programs. Crystal uses green threads, called fibers, to achieve concurrency. Fibers communicate with each other using channels, as in Go or Clojure.

...You can use rehype for many different things. unified is the core project that transforms content with ASTs. rehype adds support for HTML to unified. hast is the HTML AST that rehype uses. Depending on the input you have and output you want, you can use different parts of rehype. If the input is HTML, you can use rehype-parse with unified. If the output is HTML, you can use rehype-stringify with unified If both the input and output are HTML, you can use rehype on its own.
