Simple implementation of html/xhtml document walker that outputs node tree representation in form of Godot Dictionary object.
- SCons
- CMake (for sigil-gumbo)
- C/C++ Compiler toolchain (for now only GCC/MinGW and Clang/Clang++ are supported out of the box)
Currently readymade solution is only available under MinGW package be it MSYS2 or Winlibs or else.
Example of command:
scons platform=windows bits=64 use_mingw=on target=release
This will automatically build sigil-gumbo, godot-cpp and gd-gumbo sources at the same time. You're required to pass either use_mingw=on or use_llvm=on for build system to know compilers you're using. Look into SConstruct.py to get all the options available.
After building you should have bin folder that has dynamically loadable objects for platforms you compiled. You can copy it straight in the root of your project and use res:https://bin/gd-gumbo.gdns script for instancing parser class.
Example:
extends Node
const example := """
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<h1 class="my-style">My First Heading</h1>
<p attrib="something" another-one="hello world!">My first paragraph.</p>
</body>
</html>
"""
