I like to extend the matlab editor with a simple function.

If i press "(" the a function is called which automatically inserts ")" and move the cursor one to the left.

I tried to figure it out like it's done with the command window here: http://www.mathworks.com/matlabcentral/newsreader/view_thread/257842View thread

Matlab Version 8

EDIT{ it's nearly that what i want. it works with the code below (at least on Matlab 8)

i used some functios of Yair Altmans editor macro to get the hEditorPane: http://UndocumentedMatlab.com/blog/EditorMacro/

Done:

apply on all opened Editor (getAll Active Editors)
run at startup -> solution startup doc
apply on newly opened edtiors

I'll Test this function and extend it. if it's stable I'll post it in the file exchange. For now feel free to copy 'n' paste it

following code allows to override the edit function. I have it in the startup file

 if overloadEDIT
      Matlab_extendEditorFunctionality(true)
      addpath(matlabroot);
      fid = fopen(fullfile(matlabroot,'edit.m'),'w');
      fprintf(fid,['function edit(str)',char(13), 'if nargin < 1 || isempty(str)',char(13),...
          'str='''';',char(13),'end',char(13), 'rmpath(matlabroot);',char(13),...
          'edit(str);',char(13), 'addpath(matlabroot);',char(13),'Matlab_extendEditorFunctionality(true);']);
      fclose(fid);
  else
      warning('off')
      rmpath(matlabroot);
      delete(fullfile(matlabroot,'edit.m'))
      warning('on')
  end

it's nearly that what i want. it works with this code below (at least on Matlab 8)

i used some functios of Yair Altmans editor macro to get the hEditorPane: http://UndocumentedMatlab.com/blog/EditorMacro/

ToDo:

apply on all opened Editor
run at startup -> solution startup doc
apply on newly opened edtiors -> solution? edit edit function
EDIT: { on active editor (file) }

function  hEditorPane = getEditor
  jEditor = com.mathworks.mde.desk.MLDesktop.getInstance.getGroupContainer('Editor');
  jMainPane = [];
  for childIdx = 1 : jEditor.getComponentCount
      componentClassName = regexprep(jEditor.getComponent(childIdx-1).class,'.*\.','');
      if any(strcmp(componentClassName,{'DTMaximizedPane','DTFloatingPane','DTTiledPane'}))
          jMainPane = jEditor.getComponent(childIdx-1);
          break;
      end
  end
  if isa(jMainPane,'com.mathworks.mwswing.desk.DTFloatingPane')
      jMainPane = jMainPane.getComponent(0);  % a com.mathworks.mwswing.desk.DTFloatingPane$2 object
  end
  hEditorPane = [];
    jSyntaxTextPaneView = getDescendent(jMainPane.getComponent(0),[0,0,1,0,0,0,0]);
    if isa(jSyntaxTextPaneView,'com.mathworks.widgets.SyntaxTextPaneMultiView$1')
        hEditorPane(1) = handle(getDescendent(jSyntaxTextPaneView.getComponent(1),[1,0,0]),'CallbackProperties');
        hEditorPane(2) = handle(getDescendent(jSyntaxTextPaneView.getComponent(2),[1,0,0]),'CallbackProperties');
    else
        jEditorPane = getDescendent(jSyntaxTextPaneView,[1,0,0]);
        hEditorPane = handle(jEditorPane,'CallbackProperties');
    end
    function child = getDescendent(child,listOfChildrenIdx)
    if ~isempty(listOfChildrenIdx)
        child = getDescendent(child.getComponent(listOfChildrenIdx(1)),listOfChildrenIdx(2:end));
    end

set(hEditorPane ,'KeyTypedCallback',@(src,evnt)doSth_FUNCTION(src,evnt))
