Thank you for explanation of the background problem. Updating documentation as
you mention is a good next step.
Thanks as well for the proposed solution of splitting the input string, but as
long as it is just a display issue, this is not needed for test strings.
On the other side, given tkinter limitations of displaying lines longer than
2728 characters, I propose following solution for IDLE:
If line to display is longer than 2728 characters (or whatever limit you set,
let’s call it X), by default replace it with a line of X-3 initial characters
followed by ”...” (internally, just for displaying purposes ;-)). As long as
the current cursor position is not beyond X-3 column (99.99% of time working
with the script), display the truncated line.
This will avoid confusion, as users will not see “empty”/”strange” lines
browsing through the code and if someone really wants to manually edit
character after the X-3 column, the display will be adapted accordingly.
Let me know what you think about it.
