Can "inline.completion" support deleting or replacing certain characters?

IntelliJ Platform

Hi IntelliJ Community,

I’m working on implementing inline code completion using the com.intellij.codeInsight.inline.completion API. While the InlineCompletionElement interface provides skip and insert components for basic operations, I’m encountering scenarios where I need to: Delete existing characters or Replace specific ranges of text.

example:

// original
addThreeNumbers(x, y, z)

// user input
addTwoNumbers(x, y, z)

// we want to suggest
// delete ', z'
addTwoNumbers(x, y)

Questions:

  1. Is there a dedicated API or component for text deletion/replacement within inline completion?
    2.If not, do you have any suggestions?
