Using IDE scripting console in Intellij IDEA

Some time ago, Intellij added option to write simple scripts to automate it's functions, extract information and write simple plugins. It is located under Tools / IDE scripting console. It is very basic now, just scripting file that runs inside of Intellij JVM and has access to Intellij API.

 There is simple Groovy example that automatically adds non-suspending breakpoint with log expression:

import com.intellij.openapi.vfs.LocalFileSystem
import com.intellij.openapi.fileEditor.FileDocumentManager
import com.intellij.openapi.project.ProjectManager
import com.intellij.xdebugger.breakpoints.SuspendPolicy

def file = LocalFileSystem.getInstance().findFileByPath("/users/test/project/src/")
def doc = FileDocumentManager.getInstance().getDocument(file)
def bp = ProjectManager.getInstance().getOpenProjects()[0].getComponent("DebuggerManager").getBreakpointManager().addLineBreakpoint(doc, 11)

Of course, this basic task can be done through XML configuration, but IDE scripting has access to much more and can do trickier tasks. There is very cool demo. Generally, from what I have seen, API is pretty impressive, it is intuitive, powerful and easy to start with.

My biggest complains are that it is pretty verbose (as Java itself), it would be great if in future versions it would be solved at least at tooling levels - with auto imports for packages, autocompletion, and more convenience functions, like attaching to actions, getting projects or files quickly. Second problem is total lack of documentation. Basically, what I have found is only GitHub repo of Intellij community edition. It has multiple modules with API scattered across them, most generic classes are under Core API.


  1. Hi,

    Apologies for promoting my own plugin, but in case you didn't come across it

    It has similar features and imho is a bit more practical than IDE console (at least at the moment, no idea what plans jetbrains have for it).
