There is now a syntax-highlighter for the Eclipse IDE.
The source can be found here: http://sourceforge.net/projects/eclipse-lol
The Beta release of the plugin is out. For news see the project homepage (http://eclipse-lol.sourceforge.net/). You can find official releases at: http://eclipse-lol.sourceforge.net/update/release You can download beta releases using the following update site: http://eclipse-lol.sourceforge.net/update/beta/
I'm working on some major renovations, and hopefully going to incorporate support for all the extraneous LOLcode implementations that don't have IDEs.
To use the LOLCode functionality, create a new project. Right-click on the project, and click the “Add LOLCode Nature” action.
Right click on the project and select new. There should be an LOLCode section with “new LOLCode script”. This will create a standard “hai wurld!” applicaiton.
If you go to the run menu, you can create a new run configuration to execute this script. I'll post more info on this, as I'm still debugging this feature. I also plan to use 3rd-party implementations for this.
After the script is executed, the live interpreter should be left running if you want to try out any more code in the run window.
Enjoy, feel free to contribute. If you have an implementation of the LOLCode runtime that you would like me to incorporate, send me an Email and I'll let you know what info I need to do so
