A minimal-footprint terminal for OpenGL 3.3.

• Easy setup (see docs)
• Extensible interfaces that allow for user-defined shell and terminal implementations.
• Tested with Visual Studio 2019 and g++ (GCC) 9.3.0 (as of version 2.0.0)
• Terminal frontend
  • Polymorphic
    • There's only one implementation
  • Polymorphic fonts
    • Bitmap font support
    • Vector font support (uses Freetype)
  • Colored text (full RGB support!)
  • UTF-8 support
  • Scrolling
  • Dynamic initialization of OpenGL resources
  • User input
  • Input area control (clear/set)
  • Caller OpenGL state preserved when rendering
  • No-throw policy; Font and BmpFont are the only classes that throw exceptions, and only <stdexcept> members from their contructors (this is not the case for shell-related classes).
• Shell backend
  • Polymophic
    • Shell with advanced type-based argument parser
    • Basic shell that simply breaks up arguments into a vector

Hosted here, but you can also generate it during the build process yourself. Also, as of 2.0.0, docs are included in every release.

Welcome, as always. See CONTRIBUTING.
