copied_text function maintained in copy_text() until deletion

[rustbasic]

My opinion is that it would be better to keep the current copied_text without deprecating it, rather than creating a new function to identify or modify the content on the clipboard.

at least until copied_text is removed, the copy_text() function should continue to use copied_text in the same way it currently does.

Note that it might take a couple seconds for the update to show up after the preview_build workflow has completed.

This should be longer.

why?

[rustbasic]

why?

copied_text is needed in the following cases:

1. When checking characters copied to the clipboard.
2. When changing characters such as ' ', '\t', '\r', '\n'.
3. When filtering characters copied to the clipboard (deleting, prohibiting, changing).
4. When encrypting and restoring the clipboard for security purposes."

But why not iterate over PlatformOutput::commands and do the same logic there?

But why not iterate over PlatformOutput::commands and do the same logic there?

In typical scenarios, we use PlatformOutput::commands. However, there are cases where we need to immediately know or modify the content copied from TextEdit. Also, the current PlatformOutput::commands functionality doesn't seem to have a feature to retrieve the content. Even if a feature to retrieve the content existed, it wouldn't address situations where immediate modification is required.
