The 0.3.0 Clickity Update brings a clickable math editor! Also, this release cleans up various bugs and unexpected behavior from the previous release, namely 0.2.0 Editor Update.

Clickable math editors are enabled with:

var view = new SkiaSharp.Views.Forms.SKCanvasView { HeightRequest = 225 };
var keyboard = new CSharpMath.Rendering.MathKeyboard();
keyboard.BindDisplay(view, new CSharpMath.SkiaSharp.MathPainter {
  TextColor = SKColors.Black
}, new SkiaSharp.SKColor(0, 0, 0, 153)); // BindDisplay automatically enables touch!

keyboard.KeyPress(CSharpMath.Editor.MathKeyboardInput.X); // Wire input like this

Breaking changes

• All packages are now based on .NET Standard 2.0 instead of 1.1/1.3. (Ported into net standard 2.0 #66)
• CSharpMath.Forms.MathKeyboard has been removed and now lives in CSharpMath.Forms.Example. Its appearance is not ideal and users should create their own interfaces to suit their own needs.

Leftovers from 0.2.0

The following items are still on the roadmap but they are expected to be delayed until I or someone else has the time to work on them:

• .Net LaTeX projects #4 Merge with wpf-math
  • F# instead of C# (just as interoperable but much more maintainable)
  • Refactor TextAtoms and MathAtoms to have common atoms
  • Refactor MathAtoms to get rid of MathAtomType and AtomCloner
  • Unit tests (and picture comparisons)
  • Tavis CI integration
  • An intuitive README for getting started
  • Documentation on both NuGet and GitHub wiki
  • Document release procedure
  • Promote awareness!!
  • Native platform support for the popular ones
• Implement \middle
• Optimize loading times of the Android example project

Items to add to the roadmap

#58 will probably be higher on the roadmap as it can provide an easy-to-use interface and even attract new contributors.

Last but not least, wish you a merry Christmas 🎄 and a happy new year 🎆!

Supercedes #29.
