the cost of computing freedom is eternal vigilance
### tk.py
*originally posted:* may 2025
this is a project to recreate and zero-clause bsd license the gui code that she was built on top of, using pydocs (the gui, the text widget) and tutorials (the menu) without the gui code from she. lines i figured out and added to she (which ultimately constitutes most of the code, but not the original gui used) will be included, such as the line to change the background colour.
this will make it possible for me to re-license the bulk of the code, which i am the author of, and create an updated version of she with a permissive license. im not against the gpl, i have tried adding it to some of my larger projects, but it has failed to do more good for my own purposes than a bsd/mit/isc style license.
by the original authors admission, creating a gui using tkinter is a relatively trivial task. im not fond of the oop syntax typical of most guis (including curses) and i prefer the way this was done in the older versions of she, but based on the following code you can see that getting from a form with two buttons to a text editor with a menu does not take a very significant amount of code.

notes = """
the purpose of this program is to initialise / use a text widget
without the code originally used to create the she editor.
code added by the author to she will be used, while gpl code from other
authors will be avoided.
she was built by a single author, after adapting an existing
gpl-licensed editor.
the goal is to recreate that editor using pydocs and tutorials, so the
remaining code from she can be added and then re-licensed by the author.
