v0.21.0

Viewport improvements

Finally, viewport finally has horizontal scrolling ✨![^v1] To enable it, use SetHorizontalStep (default in v2 will be 6).

You can also scroll manually with ScrollLeft and ScrollRight, and use SetXOffset to scroll to a specific position (or 0 to reset):

vp := viewport.New()
vp.SetHorizontalStep(10) // how many columns to scroll on each key press
vp.ScrollRight(30)       // pan 30 columns to the right!
vp.ScrollLeft(10)        // pan 10 columns to the left!
vp.SetXOffset(0)         // back to the left edge

To make the API more consistent, vertical scroll functions were also renamed, and the old ones were deprecated (and will be removed in v2):

// Scroll n lines up/down:
func (m Model) LineUp(int)     // deprecated
func (m Model) ScrollUp(int)   // new!
func (m Model) LineDown(int)   // deprecated
func (m Model) ScrollDown(int) // new!
// Scroll half page up/down:
func (m Model) HalfViewUp() []string   // deprecated
func (m Model) HalfPageUp() []string   // new!
func (m Model) HalfViewDown() []string // deprecated
func (m Model) HalfPageDown() []string // new!
// Scroll a full page up/down:
func (m Model) ViewUp(int) []string   // deprecated
func (m Model) PageUp(int) []string   // new!
func (m Model) ViewDown(int) []string // deprecated
func (m Model) PageDown(int) []string // new!

[!NOTE] In v2, these functions will not return lines []string anymore, as it is no longer needed due to HighPerformanceRendering being deprecated as well.

Other improvements

The list bubble got a couple of new functions: SetFilterText, SetFilterState, and GlobalIndex - which you can use to get the index of the item in the unfiltered, original item list.
