[ease-dev] Code example to comment out a line in an editor

["Paul D. Fernhout" <pdfernhout@xxxxxxxxxxxxxxxxxx>]

Here is a proof-of-concept code example to comment out a line in an active editor. It does not check for error conditions. It relies on yesterday's changes by Christian to install itself and to get the active editor.

Notice that I evaluate the code on the UI thread to avoid a wrong thread exception. Probably only the last couple lines required running on the UI thread though. This works, but is there a better general way to run code on the UI thread so that it does not need to be passed in as a string (which makes it hard to maintain in a js file is JSHint won't check it and it won't be highlighted correctly)? I guess I could use the file commands to load the code from another file, but maybe there is some other approach?

executeUI("" +
"var editor = getActiveEditor();\n" + 
"var dp = editor.getDocumentProvider();\n" + 
"var doc = dp.getDocument(editor.getEditorInput());\n" + 
"var textSel = editor.getSelectionProvider().getSelection();\n" + 
"var newText = '/*' + textSel.getText() + '*/';\n" + 
"doc.replace(textSel.getOffset(), textSel.getLength(), newText);\n" + 
"");
// End of code example
