![]() ![]() getParent Ĭatch error ( 'Cannot find Matlab editor handle: possibly no open documents' ) Īnother complication arose due to the different layout used for floating/maximized/tiled document layout in the editor. getGroupContainer ( 'Editor' ) Ĭatch % Matlab 6 try %desktop = .MLDesktop.getMLDesktop % no use: can't get to the editor from the desktop handle in Matlab 6. Note that the desktop handle is only useful to get the editor handle in Matlab 6 – we need a totally different way in Matlab 6: #Layouteditor macro functions how to#Please feel free to look at EditorMacro‘s source code for the clearly-marked Matlab 6 segments.įor the record, here is a snippet showing how to get the editor object in Matlab 6 and 7. Luckily, once I found out how to get a handle to the Matlab 6 editor object (this took some hours of trial-and-error), listing its display hierarchy was simple and the modifications were generally straight-forward, although non-trivial (different quirks due to missing default type-castings, missing eventData in invoked callbacks etc…). This was no easy feat: Matlab 7 made some significant changes to the editor layout. I have taken great pains to make EditorMacro compatible with all Matlab versions since 6.0 (R12). Keybindings are normalized using Java’s built-in () method, to enable the user a very wide range of keystroke naming formats (e.g., ‘Alt-Control-T’ or ‘ctrl alt t’). Here’s a typical usage example: start by defining a simple function that returns a dynamic header comment: This enables EditorMacro to be used for quickly inserting code templates (header comments, try-catch blocks etc.) or for automating Matlab unit testing. Depending on the macro type, some text can be inserted at the current editor caret position, or replacing the selected editor text, or a non-text Matlab function/command can be invoked. If a match is found, then the associated macro is invoked. The list itself is persisted in the editor object’s hidden ApplicationData property (accessible via the getappdata/ setappdata built-in functions). This internal function then checks each keystroke against a list of registered keybindings. In a nutshell, EditorMacro sets the KeyPressedCallback property ( explained in a previous post) for each of the editor’s document panes, to an internal function. In this post I will detail some of its inner workings, which rely on undocumented Matlab features. #Layouteditor macro functions download#All this prompted me to finally post a solution to this need: My EditorMacro utility is now available for download on the Mathworks File Exchange. The latest user comment on this issue was posted on the official Matlab Desktop blog yesterday. Coincidentally, some weeks ago I was approached by a reader (Grant Roch) to help with assigning some textual editor macros, and with joint work we were able to figure out a basic working mechanism. Some posters have even noted this lack as their main reason to use an external editor. Over the past years there have been quite a few requests to enable keyboard macros and keybinding modifications in the Matlab editor. ![]()
