Batch rename of methods using IntelliJ IDEA

Question

I have a class with many (approximately 40) methods with names in SCREAMING_CASE_LIKE_THIS.

Is there a quick way, perhaps via the code analysis/inspections, to rename all of these to more idiomatic names in camelCaseLikeThis?

I'm not very sure about this so I'm not going to post it as an answer. But, there is a feature called structural search and replace in Intellij. It might be able to do what you're talking about. But, I could never figure out how to use it. – Malkamalkah

@DanielKaplan, thanks for the suggestion. It doesn't look like SSR will do what I want in this case. I've been a bigger user of ReSharper for C# than IDEA over the last few years and there they have a way of specifying and enforcing naming conventions. I'm hoping to use the same for Java as well. – Latvina

Maybe this can be helpful: blogs.jetbrains.com/idea/2007/01/… I don't know if there's a way to change the names in bulk though. – Malkamalkah

@DanielKaplan, with that enabled you can, from the popup, select Fix all *** problems which takes you through each one in turn with a dialog. You can select a conformant name from the drop down. Definitely easier, but not as easy as it could be. – Latvina

Hi Drew, did you use SSR for renaming your method? I'd like to rename my fieldnames but I'm having trouble. Can you provide an example? – Karlene

@Goot, sorry, this was a while back and I don't recall. – Latvina

Answer 1

It's not quite a batch, but if you position the cursor above the first of the methods, start a macro recording then do: control-alt-down shift-f6 down-arrow down-arrow carriage-return

then stop the macro, you now have a macro that goes to the next method and renames it as you desired (camel case, without underscores). You can then assign that macro to a shortcut and repeat the appropriate number of times. I tried adding the last step to the macro as being a key combination which was not bound, then assigning that combination to the macro itself (so it was self calling) but I could not get that to work. Also tried creating another macro which invoked the first x times, but that would also not work for some reason.
