Overview ¶
Package input provides the multi-line text entry component used at the bottom of the chat UI. It wraps the bubbles/textarea widget and adds the following behaviours:
- Pressing Ctrl+J with non-empty text emits a SubmitMsg and clears the field, leaving the widget focused for the next message. Whitespace-only input is silently discarded.
- Plain Enter inserts a newline (multi-line composition).
- The textarea grows automatically up to maxHeight rows as content is added, and shrinks back to 1 row on submit/reset.

Types ¶
type Model ¶
type Model struct {
// contains filtered or unexported fields
}
Model wraps a bubbles/textarea.Model. It is a value type in keeping with Bubble Tea conventions; Focus and Blur take pointer receivers because they mutate the internal widget state that must persist across Update calls.
func New ¶
func New() Model
New returns a blurred input widget. The parent model must explicitly call Focus when transitioning to InsertMode.
func (*Model) Focus ¶
Focus gives the textarea keyboard focus. Returns a blink command.
func (Model) Focused ¶
Focused returns true when the underlying textarea has keyboard focus.
func (Model) Height ¶
Height returns the current textarea height in lines.
func (Model) Init ¶
Init satisfies tea.Model; returns the cursor-blink command.
func (*Model) SetMaxHeight ¶
SetMaxHeight sets the maximum number of rows the textarea may grow to.
func (*Model) SetValue ¶
SetValue sets the textarea content and recalculates the height.
func (*Model) SetWidth ¶
SetWidth constrains the visible typing area. Subtract 2 so the parent-allocated width includes the "> " prompt the textarea owns.
func (Model) Update ¶
Update handles incoming messages. Ctrl+J submits; all other keys are forwarded to the underlying textarea.
