In reply to mb. This is indeed a very good example of the risks in using internal Matlab components - their API can change dramatically from one release to another, without prior notice. Here is the alternative in the latest Matlab release (12a):

% Get the reference to the editor application
jEditorApp = com.mathworks.mde.editor.MatlabEditorApplication.getInstance;
jEditorApp = com.mathworks.mlservices.MLEditorServices.getEditorApplication;  % an alternative

% Save the current file
jEditorApp.getActiveEditor.save();
jEditorApp.getActiveEditor.saveAs(filename);

Other useful methods of the jEditorApp.getActiveEditor reference are:

addEventListener(com.mathworks.matlab.api.editor.EditorEventListener)
addPropertyChangeListener(java.beans.PropertyChangeListener)
addPropertyChangeListener(java.lang.String, java.beans.PropertyChangeListener)
appendText(java.lang.String)
bringToFront()
close()
closeNoPrompt()
dispose()

Hi,
In Matlab 2011 com.mathworks.mlservices.MLEditorServices has no such method as saveDocument.
Instead of it one can use matlab editor api to save the document:

filehandle = matlab.desktop.editor.getActive 
filehandle.save() ;

More about it can be found here http://blogs.mathworks.com/desktop/2011/05/09/r2011a-matlab-editor-api/ .
I hope it will save someone’s time.

Regards,
mb

In reply to jo. @Jo - Here's a snippet of a sample macro (callback) function:

function myCallback(jDocument, jEventData, varargin)
   filename = jDocument.getFilename;
   % do some user-defined stuff

   % Now save the file:
   com.mathworks.mlservices.MLEditorServices.saveDocument(filename);
end  % myCallback

Also look at Perttu's KeyBindings utility for other usage examples of MLEditorServices. Yair

Thanks!
EditorMacro has been added to the startup.m file! 🙂
So far I’ve created few macros that remarkably speed up my work.
One of them is a macro that executes code between tags embedded in a comment of an m-file – excellent alternative for Edit Run Configuration… + F5 combination during debugging an m-file, but… I cannot solve one problem: automatic saving file before run (eg. to activate fresh breakpoints).
Your post about internal commands gave me new hope. I’ve made some trials to save m-file programmatically but without effect.

Do you know if such an action is possible from inside the macro?
