Copilot / Inline Suggestion

SweetEditor provides a Compose-side inline suggestion layer built around phantom text.

Main Types

• InlineSuggestion
• InlineSuggestionController
• InlineSuggestionListener

Show A Suggestion

controller.inlineSuggestions().show(
    InlineSuggestion(
        line = 12,
        column = 8,
        text = "println(value)",
    )
)

Built-in Interaction

When a suggestion is visible:

• Tab accepts it
• Escape dismisses it
• the action bar can also accept or dismiss it

Listen For Accept / Dismiss

controller.inlineSuggestions().setListener(
    object : InlineSuggestionListener {
        override fun onSuggestionAccepted(suggestion: InlineSuggestion) {
            println("accepted: ${suggestion.text}")
        }

        override fun onSuggestionDismissed(suggestion: InlineSuggestion) {
            println("dismissed: ${suggestion.text}")
        }
    }
)

Notes

• Inline suggestion is currently implemented in the Compose/Kotlin layer
• It does not require C++ core changes
• Rendering is driven through phantom text decoration updates
