Customize font faces, sizes, and colorization attributes. Set indentation
defaults. Customize keybindings. Colorization and keybindings can be
saved as user defined sets. Select startup options including shell/editor
and default window size. Define additional help sources.
Note that tab width in IDLE is currently fixed at eight due to Tk issues.
Refer to comments in EditorWindow autoindent code for details.

This code is generic - it works for any and all IDLE extensions.
IDLE extensions save their configuration options using idleConf.
This code reads the current configuration using idleConf, supplies a
GUI interface to change the configuration values, and saves the
changes using idleConf.
Not all changes take effect immediately - some may require restarting IDLE.
This depends on each extension's implementation.
All values are treated as text, and it is up to the user to supply
reasonable values. The only exception to this are the 'enable*' options,
which are boolean, and can be toggled with a True/False button.
Methods:
load_extensions:
extension_selected: Handle selection from list.
create_extension_frame: Hold widgets for one extension.
set_extension_value: Set in userCfg['extensions'].
save_all_changed_extensions: Call extension page Save().

Fonts: Enable users to provisionally change font face, size, or
boldness and to see the consequence of proposed choices. Each
action set 3 options in changes structuree and changes the
corresponding aspect of the font sample on this page and
highlight sample on highlight page.
Function load_font_cfg initializes font vars and widgets from
idleConf entries and tk.
Fontlist: mouse button 1 click or up or down key invoke
on_fontlist_select(), which sets var font_name.
Sizelist: clicking the menubutton opens the dropdown menu. A
mouse button 1 click or return key sets var font_size.
Bold_toggle: clicking the box toggles var font_bold.
Changing any of the font vars invokes var_changed_font, which
adds all 3 font options to changes and calls set_samples.
Set_samples applies a new font constructed from the font vars to
font_sample and to highlight_sample on the highlight page.
Tabs: Enable users to change spaces entered for indent tabs.
Changing indent_scale value with the mouse sets Var space_num,
which invokes the default callback to add an entry to
changes. Load_tab_cfg initializes space_num to default.

Enable users to provisionally change foreground and background
colors applied to textual tags. Color mappings are stored in
complete listings called themes. Built-in themes in
idlelib/config-highlight.def are fixed as far as the dialog is
concerned. Any theme can be used as the base for a new custom
theme, stored in .idlerc/config-highlight.cfg.
Function load_theme_cfg() initializes tk variables and theme
lists and calls paint_theme_sample() and set_highlight_target()
for the current theme. Radiobuttons builtin_theme_on and
custom_theme_on toggle var theme_source, which controls if the
current set of colors are from a builtin or custom theme.
DynOptionMenus builtinlist and customlist contain lists of the
builtin and custom themes, respectively, and the current item
from each list is stored in vars builtin_name and custom_name.
Function paint_theme_sample() applies the colors from the theme
to the tags in text widget highlight_sample and then invokes
set_color_sample(). Function set_highlight_target() sets the state
of the radiobuttons fg_on and bg_on based on the tag and it also
invokes set_color_sample().
Function set_color_sample() sets the background color for the frame
holding the color selector. This provides a larger visual of the
color for the current tag and plane (foreground/background).
Note: set_color_sample() is called from many places and is often
called more than once when a change is made. It is invoked when
foreground or background is selected (radiobuttons), from
paint_theme_sample() (theme is changed or load_cfg is called), and
from set_highlight_target() (target tag is changed or load_cfg called).
Button delete_custom invokes delete_custom() to delete
a custom theme from idleConf.userCfg['highlight'] and changes.
Button save_custom invokes save_as_new_theme() which calls
get_new_theme_name() and create_new() to save a custom theme
and its colors to idleConf.userCfg['highlight'].
Radiobuttons fg_on and bg_on toggle var fg_bg_toggle to control
if the current selected color for a tag is for the foreground or
background.
DynOptionMenu targetlist contains a readable description of the
tags applied to Python source within IDLE. Selecting one of the
tags from this list populates highlight_target, which has a callback
function set_highlight_target().
Text widget highlight_sample displays a block of text (which is
mock Python code) in which is embedded the defined tags and reflects
the color attributes of the current theme and changes for those tags.
Mouse button 1 allows for selection of a tag and updates
highlight_target with that tag value.
Note: The font in highlight_sample is set through the config in
the fonts tab.
In other words, a tag can be selected either from targetlist or
by clicking on the sample text within highlight_sample. The
plane (foreground/background) is selected via the radiobutton.
Together, these two (tag and plane) control what color is
shown in set_color_sample() for the current theme. Button set_color
invokes get_color() which displays a ColorChooser to change the
color for the selected tag/plane. If a new color is picked,
it will be saved to changes and the highlight_sample and
frame background will be updated.
Tk Variables:
color: Color of selected target.
builtin_name: Menu variable for built-in theme.
custom_name: Menu variable for custom theme.
fg_bg_toggle: Toggle for foreground/background color.
Note: this has no callback.
theme_source: Selector for built-in or custom theme.
highlight_target: Menu variable for the highlight tag target.
Instance Data Attributes:
theme_elements: Dictionary of tags for text highlighting.
The key is the display name and the value is a tuple of
(tag name, display sort order).

Enable users to provisionally change both individual and sets of
keybindings (shortcut keys). Except for features implemented as
extensions, keybindings are stored in complete sets called
keysets. Built-in keysets in idlelib/config-keys.def are fixed
as far as the dialog is concerned. Any keyset can be used as the
base for a new custom keyset, stored in .idlerc/config-keys.cfg.
Function load_key_cfg() initializes tk variables and keyset
lists and calls load_keys_list for the current keyset.
Radiobuttons builtin_keyset_on and custom_keyset_on toggle var
keyset_source, which controls if the current set of keybindings
are from a builtin or custom keyset. DynOptionMenus builtinlist
and customlist contain lists of the builtin and custom keysets,
respectively, and the current item from each list is stored in
vars builtin_name and custom_name.
Button delete_custom_keys invokes delete_custom_keys() to delete
a custom keyset from idleConf.userCfg['keys'] and changes. Button
save_custom_keys invokes save_as_new_key_set() which calls
get_new_keys_name() and create_new_key_set() to save a custom keyset
and its keybindings to idleConf.userCfg['keys'].
Listbox bindingslist contains all of the keybindings for the
selected keyset. The keybindings are loaded in load_keys_list()
and are pairs of (event, [keys]) where keys can be a list
of one or more key combinations to bind to the same event.
Mouse button 1 click invokes on_bindingslist_select(), which
allows button_new_keys to be clicked.
So, an item is selected in listbindings, which activates
button_new_keys, and clicking button_new_keys calls function
get_new_keys(). Function get_new_keys() gets the key mappings from the
current keyset for the binding event item that was selected. The
function then displays another dialog, GetKeysDialog, with the
selected binding event and current keys and allows new key sequences
to be entered for that binding event. If the keys aren't
changed, nothing happens. If the keys are changed and the keyset
is a builtin, function get_new_keys_name() will be called
for input of a custom keyset name. If no name is given, then the
change to the keybinding will abort and no updates will be made. If
a custom name is entered in the prompt or if the current keyset was
already custom (and thus didn't require a prompt), then
idleConf.userCfg['keys'] is updated in function create_new_key_set()
with the change to the event binding. The item listing in bindingslist
is updated with the new keys. Var keybinding is also set which invokes
the callback function, var_changed_keybinding, to add the change to
the 'keys' or 'extensions' changes tracker based on the binding type.
Tk Variables:
keybinding: Action/key bindings.
Methods:
load_keys_list: Reload active set.
create_new_key_set: Combine active keyset and changes.
set_keys_type: Command for keyset_source.
save_new_key_set: Save to idleConf.userCfg['keys'] (is function).

Return frame of widgets for General tab.
Enable users to provisionally change general options. Function
load_general_cfg initializes tk variables and helplist using
idleConf. Radiobuttons startup_shell_on and startup_editor_on
set var startup_edit. Radiobuttons save_ask_on and save_auto_on
set var autosave. Entry boxes win_width_int and win_height_int
set var win_width and win_height. Setting var_name invokes the
default callback that adds option to changes.
Helplist: load_general_cfg loads list user_helplist with
name, position pairs and copies names to listbox helplist.
Clicking a name invokes help_source selected. Clicking
button_helplist_name invokes helplist_item_name, which also
changes user_helplist. These functions all call
set_add_delete_state. All but load call update_help_changes to
rewrite changes['main']['HelpFiles'].

r a7 When you click either the Apply or Ok buttons, settings in this
dialog that are different from IDLE's default are saved in
a .idlerc directory in your home directory. Except as noted,
these changes apply to all versions of IDLE installed on this
machine. [Cancel] only cancels changes made since the last save.

Font sample: This shows what a selection of Basic Multilingual Plane
unicode characters look like for the current font selection. If the
selected font does not define a character, Tk attempts to find another
font that does. Substitute glyphs depend on what is available on a
particular system and will not necessarily have the same size as the
font selected. Line contains 20 characters up to Devanagari, 14 for
Tamil, and 10 for East Asia.
Hebrew and Arabic letters should display right to left, starting with
alef, א and ا. Arabic digits display left to right. The
Devanagari and Tamil lines start with digits. The East Asian lines
are Chinese digits, Chinese Hanzi, Korean Hangul, and Japanese
Hiragana and Katakana.
You can edit the font sample. Changes remain until IDLE is closed.

Highlighting:
The IDLE Dark color theme is new in October 2015. It can only
be used with older IDLE releases if it is saved as a custom
theme, with a different name.
z�
Keys:
The IDLE Modern Unix key set is new in June 2016. It can only
be used with older IDLE releases if it is saved as a custom
key set, with a different name.

General:
AutoComplete: Popupwait is milliseconds to wait after key char, without
cursor movement, before popping up completion box. Key char is '.' after
identifier or a '/' (or '\' on Windows) within a string.
FormatParagraph: Max-width is max chars in lines after re-formatting.
Use with paragraphs in both strings and comment blocks.
ParenMatch: Style indicates what is highlighted when closer is entered:
'opener' - opener '({[' corresponding to closer; 'parens' - both chars;
'expression' (default) - also everything in between. Flash-delay is how
long to highlight if cursor is not moved (0 means forever).
CodeContext: Maxlines is the maximum number of code context lines to
display when Code Context is turned on for an editor window.
Shell Preferences: Auto-Squeeze Min. Lines is the minimum number of lines
of output to automatically "squeeze".
a�
ZzDummy: This extension is provided as an example for how to create and
use an extension. Enable indicates whether the extension is active or
not; likewise enable_editor and enable_shell indicate which windows it
will be active on. For this extension, z-text is the text that will be
inserted at or removed from the beginning of the lines of selected text,
or the current line if no selection.
