## Summary Closes #64273 Running a case conversion (or any other `manipulate_text` command) with several cursors inside the same word inserted the converted word once per cursor: | Before | Upper case result | |---|---| | `some_ˇvariˇable_naˇme` | `SOME_VARIABLE_NAMESOME_VARIABLE_NAMESOME_VARIABLE_NAME` | ### Cause `manipulate_text` expands each empty selection to its surrounding word, so several cursors in one word produce identical ranges, and a cursor's word can also overlap other selections. The buffer coalesces overlapping edits by concatenating their texts, so the converted text was inserted once per selection. ### Fix After expanding, the ranges are sorted by start and overlapping ones are merged, then each merged range is transformed once. Sorting matters because expanding a cursor can move its range's start before earlier selections (e.g. `«a»b«cd»e|f`, where the cursor's word starts at `a`). Selections that only touch are kept separate, so non-overlapping selections behave exactly as before. This applies to every command that goes through `manipulate_text`: all case conversions, ROT13/ROT47, and Base64 encode/decode. ## Testing Added `test_multicursor_manipulate_text`, which reports every failing case at once. It covers: - multiple cursors in one word, and in two different words - a cursor's word partially overlapping a selection - a cursor's word starting before earlier selections - a conversion that changes nothing, which keeps the cursors unchanged ## Self-review - [x] I've reviewed my diff for quality, security, reliability, and performance. - [x] Tests cover the new or changed behavior. Release Notes: - Fixed case conversion and other text transformation commands duplicating the word when multiple cursors are inside it. |
