"""Provides access to stored IDLE configuration information.
|
|
|
|
Refer to the comments at the beginning of config-main.def for a description of
|
|
the available configuration files and the design implemented to update user
|
|
configuration information. In particular, user configuration choices which
|
|
duplicate the defaults will be removed from the user's configuration files,
|
|
and if a file becomes empty, it will be deleted.
|
|
|
|
The contents of the user files may be altered using the Options/Configure IDLE
|
|
menu to access the configuration GUI (configDialog.py), or manually.
|
|
|
|
Throughout this module there is an emphasis on returning useable defaults
|
|
when a problem occurs in returning a requested configuration value back to
|
|
idle. This is to allow IDLE to continue to function in spite of errors in
|
|
the retrieval of config information. When a default is returned instead of
|
|
a requested config value, a message is printed to stderr to aid in
|
|
configuration problem notification and resolution.
