By the end of this week or so I'll release a new version of the plugin that will fix that issue.

If meanwhile you want to play with a BETA snapshot of the new plugin, do the following:

Clearing out the old plugin
-Start IDEA
-Open Project Structure (Configure->Project Defaults->Project Structure)
-Go to SDKs on the left
-Delete Default Gosu SDK if it exists
-Close the Project Structure dialog
-Go to Plugins (Configure->Plugins)
-Right-click on the Gosu plugin, if it exists, and Uninstall
-Right-click on the Gosu Debugger plugin, if it exists, and Uninstall
-Close the Settings dialog. Restart IDEA when prompted.

Installing the new plugin
-Download this
-Start IntelliJ IDEA
-Ensure you are using IntelliJ IDEA version 12.1 or later
-Ensure IntelliJ IDEA uses 1.7
-Go to Plugins (Configure->Plugins)
-Click Install plugin from disk...
-Select the zip you downloaded
-Close the Settings dialog. Restart IDEA when prompted

Thank you Luca for quick reply!  After implementing the changes you suggested, I am now receiving a "No Gosu SDK found" error message when trying to create a project.  Screenshot of error is attached.

Select the default gosu sdk and press finish

LOL!  I'm embarrassed!  Just a usability enhancement suggestion.  The little blue circle with a "c" inside on the left side of the "Default Gosu SDK..." looks like a selected radio button, so I thought that row was selected by default.  

Thank you again for amazingly fast reply.

[Luca Boasso]

That's an Intellij issue, not our fault :)

No problem.

Feel free to give me some feedback so that I can fix potential issues before the official release

When I try to run the hello world example, the run toolbar icon is grayed out.  There are two "Run" menu items in the "Run" menu.  The first one is grayed out.  When I click the 2nd one, I see a dialog asking me if I want to "Edit Configurations".  Any ideas why it isn't just running?

[shawn...@gmail.com]

In the IDE, it also says "Groovy SDK is not configured for module..."  Not sure if that is related.

Uhm..quick check.
Do you see a big G at the root of your source project (like in the picture on the left)?

Are you using intellij 12?

Does your project structure have the Default Gosu Sdk as project sdk?

Have you created a gosu program like in my example (Hello.gsp)?

Have you tried to right click on Hello.gsp and press the run menu?

Yes

Yes. 12.1.4

Yes

Yes

Have you tried to right click on Hello.gsp and press the run menu?

No.  There is no "run" item in the right click menu.  Also the screenshot shows that the run toolbar button is grayed out.

I think you might have selected by mistake Groovy module when creating a new project.

Try to disable the groovy plugin and restart.

Try also to open this project.

Groovy? Like from the toilet?

You want Gosu, the Scripting Mutilator...

<HelloWorld.zip>

[Brian Chang]

It's got what IJ craves...

Thank you again!  It worked this time.  The only change I know of is that I disabled Groovy; however, I did create the project from scratch, so maybe I accidentally selected a Groovy module the first time.  But If I did select a Groovy module the first time, would it still have the big G at the root of the source project?

[Brian Chang]

You would have seen a G logo in a green circle like in this image (though in a different context):

It works for me with the Groovy plugin enabled so I think you selected by mistake the Groovy module at the beginning.

Let me know otherwise, I'll try to fix that

[shawn...@gmail.com]

I think you must be right.  

Thank you again!
