How to append action after rename file

You should use com.intellij.refactoring.rename.naming.AutomaticRenamerFactory instead which will automatically provide those renaming targets
during the actual rename operation.

I'm aimed to refactory ruby test file after rename ruby lib file, This is my example:


# lib/ex.rb
# spec/lib/ex_spec.rb

I hope when i rename lib/ex.rb to lib/ex2.rb, the spec/lib/ex_spec.rb will auto become spec/lib/ex2_spec.rb

So this is my thinking:

If I can get the value what I type in rename dialog, I can handle this value in code
and then I find public RenameElementAction#getHandler, I hope find a way to custom the handler.

my question is:


How to get rename dialog value?
How to customize getHandler in sub class of RenameElementAction
I can undo refactoring with hitting ctrl+z, If I implement above, how to undo it?

And sorry, I'm not so understand How to use AutomaticRenamerFactory to implement them, can you explain it detail according my example.

Please try to understand existing code, e.g. com.intellij.lang.properties.refactoring.rename.ResourceBundleRenamerFactory
is a very basic sample on how to use it.

"undo" support will be available automatically, as well as "preview changes"

I still has question, following is my code, if i rename ex.rb, it will change ex_test.rb, but when i hit ctrl+z to undo refactoring, ex_test.rb doesn't recovery and is changed forever. My question is how to recovery ex_test.rb

// Renamer.groovy

package ro.tryApi.spec

import com.intellij.refactoring.rename.naming.AutomaticRenamer
import com.intellij.usageView.UsageInfo

class Renamer extends AutomaticRenamer {
    Renamer() {
        new File("/home/roroco/Dropbox/try/plugin/rb/spec/lib/ex_test.rb").write(new Date().toString())
    }

    @Override
    String getDialogTitle() {
        return 'try dialog title'
    }

    @Override
    String getDialogDescription() {
        return "try dialog desc"
    }

    @Override
    String entityName() {
        return 'try entity name'
    }
}

// RenamerFactory

package ro.tryApi.spec

import com.intellij.psi.PsiElement
import com.intellij.refactoring.rename.naming.AutomaticRenamer
import com.intellij.refactoring.rename.naming.AutomaticRenamerFactory
import com.intellij.usageView.UsageInfo

class RenamerFactory implements AutomaticRenamerFactory {

    @Override
    boolean isApplicable(PsiElement psiElement) {
        return true
    }

    @Override
    String getOptionName() {
        return "try opt"
    }

    @Override
    boolean isEnabled() {
        return true
    }

    @Override
    void setEnabled(boolean b) {

    }

    AutomaticRenamer createRenamer(PsiElement e, String s, Collection<UsageInfo> c) {
        return new Renamer()
    }
}

What is this:  new File("/home/roroco/Dropbox/try/plugin/rb/spec/lib/ex_test.rb").write(new Date().toString())

IDE cannot know about such modifications and undo them. You must simply override #suggestNameForElement to provide new "automatic" filename and return false from allowChangeSuggestedName() to disallow manual editing.

Finally, I implement all feature what I need, but i find it will jump a new dialog, can you tell me how to use RenamePsiElementProcessor instead of AutomaticRenamerFactory

Finally, I find following code can fix my question:

// plugin.xml

<idea-plugin version="2">
    ...
    <extensions defaultExtensionNs="com.intellij">
        <renamePsiElementProcessor implementation="ro.tryApi.spec.RenameProcessor"></renamePsiElementProcessor>
    </extensions>
</idea-plugin>

// /home/roroco/Dropbox/try/idea-plugin/try/src/main/groovy/ro/tryApi/spec/RenameProcessor.groovy
// It's just a try code

package ro.tryApi.spec

import com.intellij.openapi.vfs.LocalFileSystem
import com.intellij.openapi.vfs.newvfs.impl.VirtualFileImpl
import com.intellij.psi.PsiElement
import com.intellij.psi.PsiFile
import com.intellij.psi.search.SearchScope
import com.intellij.refactoring.rename.RenamePsiElementProcessor
import org.jetbrains.annotations.NotNull

/**
 * Created by roroco on 5/28/15.
 */
class RenameProcessor extends RenamePsiElementProcessor {
    @Override
    boolean canProcessElement(@NotNull PsiElement psiElement) {
        psiElement.class.name.matches(/.*RFileImpl$/)
    }

    @Override
    void prepareRenaming(PsiElement e, String s, Map<PsiElement, String> map, SearchScope searchScope) {
        VirtualFileImpl vf = LocalFileSystem.instance.findFileByPath("/home/roroco/Dropbox/try/plugin/rb/spec/lib/ex2_spec.rb")
        PsiFile f = e.manager.findFile(vf)
        map[f] = new Date().toString()
        super.prepareRenaming(f, s, map, searchScope)
    }
}
