libxjr

XMLish JSONish Ragel powered parser

LibXJR is a parsing library that can parse a mixture of XML-like and JSON-like notation. It does not adhere to either standard directly, and so it cannot be strictly called either XML or JSON. The XML notation notably does not have any of the standard complexities of XML. It is XML-like in appearance only and intentionally so.

It is implemented using a Ragel state machine definition with C code at state transitions. It creates a connected tree of C structured nodes that can be navigated in a DOM like fashion.

The notation/syntax of XJR was created to make a concise easy to use syntax for defining HTML-like layout. It's purpose is to create a layout language with many more standard interactive widgets than HTML contains, so that a full interface definition can be created that does not need any custom JS code created.

This new layout language using XJR syntax is called Lumith Layout Language. It is the layout language meant to be used with the Lumith ECM system. XJR syntax is turned into a recursive JSON structure capable of being parsed by current browsers using LibJSA. JSA syntax is then passed into a modified DomCascade library for rendering into usable widgets.

Portions of the XML-Bare C library have been utilized for the base tree used in the library.

A precompiled WebAssembly version of the library has been included in the wasm directory for convenience, along with the shellscript/command used to generate it. The WebAssembly generated JS has been included in a prettified format as well as a compressed form generated via uglifyjs.
