Patch by Florian Dahlitz. What's New in IDLE 3.8.3 Released on 2020-05-13 ====================================== bpo-38689: IDLE will no longer freeze when inspect.signature fails when fetching a calltip. bpo-27115: For 'Go to Line', use a Query entry box subclass with IDLE standard behavior and improved error checking. bpo-39885: When a context menu is invoked by right-clicking outside of a selection, clear the selection and move the cursor. Cut and Copy require that the click be within the selection. bpo-39852: Edit "Go to line" now clears any selection, preventing accidental deletion.

Patch by Johnny Najera. bpo-38862: 'Strip Trailing Whitespace' on the Format menu removes extra newlines at the end of non-shell files. bpo-38636: Fix IDLE Format menu tab toggle and file indent width. These functions (default shortcuts Alt-T and Alt-U) were mistakenly disabled in 3.7.5 and 3.8.0. bpo-4630: Add an option to toggle IDLE's cursor blink for shell, editor, and output windows. See Settings, General, Window Preferences, Cursor Blink. Patch by Zackery Spytz. bpo-26353: Stop adding newline when saving an IDLE shell window. bpo-38598: Do not try to compile IDLE shell or output windows. What's New in IDLE 3.8.0 (since 3.7.0) Released on 2019-10-14 ====================================== bpo-36698: IDLE no longer fails when writing non-encodable characters to stderr. It now escapes them with a backslash, like the regular Python interpreter. Add an errors field to the standard streams. bpo-13153: Improve tkinter's handing of non-BMP (astral) unicode characters, such as 'rocket \U0001f680'. Whether a proper glyph or replacement char is displayed depends on the OS and font. For IDLE, astral chars in code interfere with editing. bpo-35379: When exiting IDLE, catch any AttributeError. One happens when EditorWindow.close is called twice. Printing a traceback, when IDLE is run from a terminal, is useless and annoying. bpo-38183: To avoid test issues, test_idle ignores the user config directory. It no longer tries to create or access .idlerc or any files within. Users must run IDLE to discover problems with saving settings. bpo-38077: IDLE no longer adds 'argv' to the user namespace when initializing it. This bug only affected 3.7.4 and 3.8.0b2 to 3.8.0b4. bpo-38401: Shell restart lines now fill the window width, always start with '=', and avoid wrapping unnecessarily. The line will still wrap if the included file name is long relative to the width. bpo-37092: Add mousewheel scrolling for IDLE module, path, and stack browsers. Patch by George Zhang. bpo-35771: To avoid occasional spurious test_idle failures on slower machines, increase the ``hover_delay`` in test_tooltip. bpo-37824: Properly handle user input warnings in IDLE shell. Cease turning SyntaxWarnings into SyntaxErrors. bpo-37929: IDLE Settings dialog now closes properly when there is no shell window. bpo-37849: Fix completions list appearing too high or low when shown above the current line. bpo-36419: Refactor autocompete and improve testing. bpo-37748: Reorder the Run menu. Put the most common choice, Run Module, at the top. bpo-37692: Improve highlight config sample with example shell interaction and better labels for shell elements. bpo-37628: Settings dialog no longer expands with font size. The font and highlight sample boxes gain scrollbars instead. bpo-17535: Add optional line numbers for IDLE editor windows. bpo-37627: Initialize the Customize Run dialog with the command line arguments most recently entered before. The user can optionally edit before submitting them. bpo-33610: Code context always shows the correct context when toggled on. bpo-36390: Gather Format menu functions into format.py. Combine paragraph.py, rstrip.py, and format methods from editor.py. bpo-37530: Optimize code context to reduce unneeded background activity. Font and highlight changes now occur along with text changes instead of after a random delay. bpo-27452: Cleanup config.py by inlining RemoveFile and simplifying the handling of __file__ in CreateConfigHandlers/ bpo-26806: To compensate for stack frames added by IDLE and avoid possible problems with low recursion limits, add 30 to limits in the user code execution process. Subtract 30 when rep
