/Lib/idlelib/configHandler.py

  1"""Provides access to stored IDLE configuration information.
  2
  3Refer to the comments at the beginning of config-main.def for a description of
  4the available configuration files and the design implemented to update user
  5configuration information.  In particular, user configuration choices which
  6duplicate the defaults will be removed from the user's configuration files,
  7and if a file becomes empty, it will be deleted.
  8
  9The contents of the user files may be altered using the Options/Configure IDLE
 10menu to access the configuration GUI (configDialog.py), or manually.
 11
 12Throughout this module there is an emphasis on returning useable defaults
 13when a problem occurs in returning a requested configuration value back to
 14idle. This is to allow IDLE to continue to function in spite of errors in
 15the retrieval of config information. When a default is returned instead of
 16a requested config value, a message is printed to stderr to aid in
 17configuration problem notification and resolution.
