No such sub-menu of Tools exists, but that's fine because I've mapped Ctrl+Shift+A to bring up the menu. I installed the Kotlin plugin and tried again. There was a missing import. After fixing the missing import:
[732 ms]=> null
> 4. Select a folder containing the classes in the Project window
> 5. Press Ctrl+Shift+A to open action menu
> 6. Search for Bulk refactor and select it
Opening the menu with Ctrl+Shift+A doesn't show the bulk refactor script, but that could be because I remapped Ctrl+Shift+A and am using the NetBeans keyboard mappings, rather than the IntelliJ map.
Oops :)
When pressing Ctrl+Enter, did you see the green "Loaded!" notification in the bottom right? If so, then I guess installing the Kotlin plugin worked.
> Opening the menu with Ctrl+Shift+A doesn't show the bulk refactor script
The Ctrl+Shift+A menu from the default keymap that I'm talking about is the "Actions" dialog. You can also get there via "Navigate -> Search Everywhere" and then selecting the "Actions" tab (or just searching in All).
Also you only have to select a single folder/package and it will be processed recursively. I did not test what happens when you select multiple folders. Might be fine, might explode.
edit: Just realized the script I pasted here does not emit the "Loaded!" log message on load. So disregard those comments. If you want to verify it loads correctly, add this as the last line:
log("Loaded!")https://i.ibb.co/MP2JNRM/classes-renamed.png
Thank you!
Then run the script like this:
1. In IDEA: Tools -> IDE Scripting Console -> Kotlin
2. Paste in the script
3. Ctrl+A, Ctrl+Enter to load the script. This should show a green "Loaded!" notification
4. Select a folder containing the classes in the Project window
5. Press Ctrl+Shift+A to open action menu
6. Search for Bulk refactor and select it
Also please note the first version of the script had a bug that would open confirmation dialogues for some refactorings, so see the edited script.
