M PyShell.py M idle M idle.py M idle.pyw M setup.py Switch back to installing IDLE as a package. The IDLE GUI and the subprocess will both attempt to start up via the package mechanism, but if IDLE is not yet installed it is possible to run by calling python idle.py in the IDLE source directory, or to add the source directory to sys.path. One advantage of doing it this way is IDLE stays off sys.path. Developed in collaboration with Tony Lownds. 2002-12-24 06:36:19 +00:00			`try:`
Issue #24225: Within idlelib files, update idlelib module names. This follows the previous patch that changed idlelib file names. Class names that matched old module names are not changed. Change idlelib imports in turtledemo.__main__. Exception: config-extensions.def. Previously, extension section names, file names, and class names had to match. Changing section names would create cross-version conflicts in config-extensions.cfg (user customizations). Instead map old names to new file names at point of import in editor.EditorWindow.load_extension. Patch extensively tested with test_idle, idle_test.htest.py, a custom import-all test, running IDLE in a console to catch messages, and testing each menu item. Based on a patch by Al Sweigart. 2016-05-28 13:22:31 -04:00			`import idlelib.pyshell`
