[issue16123] IDLE - deprecate running without a subprocess

Terry J. Reedy added the comment: Deprecation has been done and a message is printed under the splash screen. With 5 more years of maintenance experience under deprecation, I have not experienced -n mode as a maintenance burden. So I have no inclination at present to remove it (or even imp

Terry J. Reedy added the comment: I have some different ideas for this issue that would not necessarily involve removing -n. While -n is can be an inferior experience for users (user code blocks the GUI, other interference, especially tkinter), the reason given for deprecation is to simplify

Terry J. Reedy added the comment: Torgil, thank you for the interesting feedback. I will respond to your four paragraphs slightly out of order. 1. Starting Idle with '-n', I verified that running 'print(a)' from the editor works after entering 'a=1' in the shell. The intended purpose of the ed

Torgil Svensson added the comment: I frequently use IDLE as an interactive shell to Python with the Editor attached. It's very nice for this purpose as it's lightweight and embedded in Python delivery. This is only possible with -n flag as without it each press on F5 will restart the interpret

[issue16123] IDLE - deprecate running without a subprocess

New submission from Roger Serwy: Removing the option of running IDLE without a subprocess would simplify the maintenance of IDLE. This should be deprecated for 3.4 and then fully removed in 3.5. Here's a link to a brief discussion on IDLE-dev: http://mail.python.org/pipermail/idle-dev/2012-Ju
