Right after the set-text-properties call, there is a call to the variable ivy-set-prompt-text-properties-function, which is allowed to modify the prompt in-place.
Can you please describe in more detail what use-case you are considering, that can't already be addressed via ivy-set-prompt-text-properties-function?
In general, I would prefer to avoid relying on object-intervals, or needing to copy each interval over manually. At least, not by default, and not if we can think of another solution.
For example, set-text-properties could be replaced with add-text-properties. Or, std-props could be turned into a variable that can be bound around relevant calls to Ivy. But I would like to better understand the motivation before making such changes.

the
enhancement
ivy--insert-prompt seems to emulate some of read-from-minibuffer's text property logic, but hasn't been doing so correctly w.r.t minibuffer-prompt-properties and in particular the face property. This change allows users to affect the entire prompt via m-p-p, or just the prompt text itself by passing, e.g., a propertized string to ivy-read. It should support multiple faces too. * ivy.el (ivy--insert-prompt): Break text property logic out... (ivy--propertize-prompt): ...to this new function. Use add-text-properties and add-face-text-property in place of set-text-properties (#3077). Heed minibuffer-prompt-properties.

In commit 4b1df7c I generalised the current code to use This doesn't preserve all text properties, but it does preserve the same text properties as Does that address your use-case, or is a new mechanism still needed? Thanks. |

This continues from the previous commit of 2025-11-22 "Don't completely replace prompt text properties". * ivy.el (ivy-set-prompt-text-properties-default): Retain existing faces by using add-face-text-property (#3077).

I tested new version and it works. So this PR could be closed. (read-buffer (format-prompt "select buffer (\\`C-t' to toggle filtering)" nil))To suggest a non standard key binding to user. |
Great, thank you for confirming, and once again for your patience. |
