termdash v0.14.0 Release Notes

  • 💥 Breaking API changes

    • The widgetapi.Widget.Keyboard and widgetapi.Widget.Mouse methods now accepts a second argument which provides widgets with additional metadata. All widgets implemented outside of the termdash repository will need to be updated similarly to the Barchart example below. Change the original method signatures: ```go func (*BarChart) Keyboard(k *terminalapi.Keyboard) error { ... }

    func (*BarChart) Mouse(m *terminalapi.Mouse) error { ... }

    
  By adding the new `*widgetapi.EventMeta` argument as follows:
  ```go
  func (*BarChart) Keyboard(k *terminalapi.Keyboard, meta *widgetapi.EventMeta) error { ... }

  func (*BarChart) Mouse(m *terminalapi.Mouse, meta *widgetapi.EventMeta) error { ... }
