"""idlelib.config -- Manage IDLE configuration information.
|
|
|
|
The comments at the beginning of config-main.def describe the
|
|
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 user file becomes empty, it will be
|
|
deleted.
|
|
|
|
The configuration database maps options to values. Conceptually, the
|
|
database keys are tuples (config-type, section, item). As implemented,
|
|
there are separate dicts for default and user values. Each has
|
|
config-type keys 'main', 'extensions', 'highlight', and 'keys'. The
|
|
value for each key is a ConfigParser instance that maps section and item
|
|
to values. For 'main' and 'extensions', user values override
|
|
default values. For 'highlight' and 'keys', user sections augment the
|
|
default sections (and must, therefore, have distinct names).
|
|
|
|
Throughout this module there is an emphasis on returning usable 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.
