Function: shiftRunsForEdit()

function shiftRunsForEdit(
   runs,
   oldText,
   newText): object[];

Defined in: packages/timeline/src/rich-text.ts:133

Remap runs across a text edit, given the before/after strings. The edit region is recovered by common prefix/suffix; offsets after it shift, offsets inside clamp to its bounds. Typing INSIDE a styled run grows the run (the new characters inherit its style), which is what every rich editor does.

Parameters

runs

readonly object[]

oldText

string

newText

string

Returns

object[]
