@ConradIrwin Currently there is no confirmation dialog when writing to a file that already exists. Any ideas on how to fix this?

@CharlesChen0823 can you elaborate on what you mean by using prompt?

sorry，you can forget what i say，i remember the wrong API name save_item which not exist in editor

Apr 24 '25 23:04 CharlesChen0823

might you can reference the implementation here, do something similar?

@ConradIrwin I added a confirmation dialog to ask the user if they want to replace the file with the same name. Should we implement auto-completion for file names in this PR or a future PR?

Thanks! Let's leave autocomplete for a follow-up. I pushed up a change to fix w! and add a test; I think this should be good to go.
