Onetastic 4 is Available with User Defined Functions

March 01, 2019

Onetastic 4 is available with support for user defined functions. You can now add new functions with parameters in your macro and call them to re-use code and simplify your macro. This allows writing macros that do much more with less code than before especially in problems with recursive nature (e.g. macros dealing with section group hierarchy or nested tables).

Adding User Defined Functions to Macros

Macro Editor is updated for adding and editing your own functions. You can see how this works in the short recording below:

Debugging Macros with User Defined Functions

The debugger can now step into and out of user defined functions. A callstack is displayed in the debugger and you can see return values of both user defined and built-in functions in Object Browser during debugging to help investigate and identify problems:

Menus and Toolbar

Macro Editor's user interface is fully updated with menus and toolbars. You can now open macros or create new ones directly from inside the editor. A full list of menu items and their explanations can be found in the documentation.


Editing and debugging macros with user defined functions requires an active Onetastic Dev license. Licenses purchased for Onetastic 3.X.X releases will continue to work on Onetastic 4.

The OneNote android client often fails to clip an entire webpage, and instead defaults to saving only a title and a url link.

Is it possible to use a Onetastic macro to : (1) search and find pages limited to just a link; (2) then find and Insert the full webpage below the link; or (3) alternatively trigger the OneNote clipper to build a New Page with the full web content?

Sorry to post this here, but I have been unable to get the support email to work, it keeps bouncing back. I am trying to log into my account, but it wants me to verify my email address. It never sends the verification email, so I am unable to log in. Any help would be appreciated.  jack at jhecker dot net.

Omar - I'm having a problem with macros I have downloaded, copied and modified for my own purposes.  I haven't shared them because I'm fairly certain my purposes are specific to me and not something others would use.  But when I update my downloaded macros, my "personalized" macros all disappear.  Am I doing something wrong?  Thanks for any suggestions.
