Usage

Add to your openFrameworks project and initialize an editor variable passing in the number of text buffers you require (defaults to 1). For example:

class testApp : public ofBaseApp{

  ofxEmacsEditor editor;
  bool editorVisible;

public:
  testApp() : editor(9) {}

  // Editor command callbacks are static methods
  static void toggleEditor(void *);

  // ... rest of your oF app ...

};

You can define custom commands in your setup function, for example:

void testApp::setup(){
  editor.addCommand('a', this, &testApp::toggleEditor);
}

void testApp::toggleEditor(void * _o) {
  ((testApp *)_o)->editorVisible = !((testApp *)_o)->editorVisible;
}

To get the current text in the editor you need to reference the getText() method of the current buffer.

editor.buf[editor.currentBuffer]->getText();

For the editor to be visible you need to draw it in your main oF app draw loop:

if (editorVisible) {
  editor.draw();
}
