Experimental GUI

To test run with:

ipython --gui=tk -i -m oberon.IDE -- -n

Let’s break that down. We’re using ipython. The --gui=tk CLI option tells it to use the Tkinter-compatible event loop, -i tells it to drop into interactive mode after the script ends rather than exiting, -m oberon.IDE tells it to use the oberon.IDE.__main__ module as the script to run, and -- tells it to pass the rest of the CLI options to the script itself. The -n CLI option is detected by the main script and prevents it from starting the Tkinter mainloop on its own.

The combination of using IPython’s Tkinter-compatible event loop and not calling the Tkinter mainloop in the main script lets you use IPython shell while the GUI runs and updates. This is really flexible and powerful, as you have all of Python available to work with, but you have to read the source and know something about Python and Tkinter GUI code to take advantage of it.

For example, the main script creates the app and puts it in a variable w, and you can change the font properties like this:

In [1]: w.font['family'] = 'Iosevka Term'

In [2]: w.font['size'] = 12
class oberon.IDE.widgets.Breakpoints(root, font)[source]
