Fix for issue3559: No preferences menu in IDLE on OSX
1) Add a comment to the help file to that points to the
preferences menu.
2) An earlier checkin tried to detect Tk >= 8.10.14,
but did this in the wrong way. The end result of this
was that the IDLE->Preferences... menu got surpressed
when using the system version of Tcl/Tk

** TIPS **
|
|
==========
|
|
|
|
Additional Help Sources:
|
|
|
|
Windows users can Google on zopeshelf.chm to access Zope help files in
|
|
the Windows help format. The Additional Help Sources feature of the
|
|
configuration GUI supports .chm, along with any other filetypes
|
|
supported by your browser. Supply a Menu Item title, and enter the
|
|
location in the Help File Path slot of the New Help Source dialog. Use
|
|
http:// and/or www. to identify external URLs, or download the file and
|
|
browse for its path on your machine using the Browse button.
|
|
|
|
All users can access the extensive sources of help, including
|
|
tutorials, available at www.python.org/doc. Selected URLs can be added
|
|
or removed from the Help menu at any time using Configure IDLE.
|
|
|
|
Basic editing and navigation:
|
|
|
|
Backspace deletes char to the left; DEL deletes char to the right.
|
|
Control-backspace deletes word left, Control-DEL deletes word right.
|
|
Arrow keys and Page Up/Down move around.
|
|
Control-left/right Arrow moves by words in a strange but useful way.
|
|
Home/End go to begin/end of line.
|
|
Control-Home/End go to begin/end of file.
|
|
Some useful Emacs bindings are inherited from Tcl/Tk:
|
|
Control-a beginning of line
|
|
Control-e end of line
|
|
Control-k kill line (but doesn't put it in clipboard)
|
|
Control-l center window around the insertion point
|
|
Standard Windows bindings may work on that platform.
|
|
Keybindings are selected in the Settings Dialog, look there.
|
|
|
|
Automatic indentation:
|
|
|
|
After a block-opening statement, the next line is indented by 4 spaces
|
|
(in the Python Shell window by one tab). After certain keywords
|
|
(break, return etc.) the next line is dedented. In leading
|
|
indentation, Backspace deletes up to 4 spaces if they are there. Tab
|
|
inserts spaces (in the Python Shell window one tab), number depends on
|
|
Indent Width. (N.B. Currently tabs are restricted to four spaces due
|
|
to Tcl/Tk issues.)
|
|
|
|
See also the indent/dedent region commands in the edit menu.
|
|
|
|
Completions:
|
|
|
|
Completions are supplied for functions, classes, and attributes of
|
|
classes, both built-in and user-defined. Completions are also provided
|
|
for filenames.
|
|
|
|
The AutoCompleteWindow (ACW) will open after a predefined delay
|
|
(default is two seconds) after a '.' or (in a string) an os.sep is
|
|
typed. If after one of those characters (plus zero or more other
|
|
characters) you type a Tab the ACW will open immediately if a possible
|
|
continuation is found.
|
|
|
|
If there is only one possible completion for the characters entered, a
|
|
Tab will supply that completion without opening the ACW.
|
|
|
|
'Show Completions' will force open a completions window. In an empty
|
|
string, this will contain the files in the current directory. On a
|
|
blank line, it will contain the built-in and user-defined functions and
|
|
classes in the current name spaces, plus any modules imported. If some
|
|
characters have been entered, the ACW will attempt to be more specific.
|
|
|
|
If string of characters is typed, the ACW selection will jump to the
|
|
entry most closely matching those characters. Entering a Tab will cause
|
|
the longest non-ambiguous match to be entered in the Edit window or
|
|
Shell. Two Tabs in a row will supply the current ACW selection, as
|
|
will Return or a double click. Cursor keys, Page Up/Down, mouse
|
|
selection, and the scrollwheel all operate on the ACW.
|
|
|
|
'Hidden' attributes can be accessed by typing the beginning of hidden
|
|
name after a '.'. e.g. '_'. This allows access to modules with
|
|
'__all__' set, or to class-private attributes.
|
|
|
|
Completions and the 'Expand Word' facility can save a lot of typing!
|
|
|
|
Completions are currently limited to those in the namespaces. Names in
|
|
an Edit window which are not via __main__ or sys.modules will not be
|
|
found. Run the module once with your imports to correct this
|
|
situation. Note that IDLE itself places quite a few modules in
|
|
sys.modules, so much can be found by default, e.g. the re module.
|
|
|
|
If you don't like the ACW popping up unbidden, simply make the delay
|
|
longer or disable the extension. OTOH, you could make the delay zero.
|
|
|
|
You could also switch off the CallTips extension. (We will be adding
|
|
a delay to the call tip window.)
|
|
|
|
Python Shell window:
|
|
|
|
Control-c interrupts executing command.
|
|
Control-d sends end-of-file; closes window if typed at >>> prompt
|
|
(this is Control-z on Windows).
|
|
|
|
Command history:
|
|
|
|
Alt-p retrieves previous command matching what you have typed.
|
|
Alt-n retrieves next.
|
|
(These are Control-p, Control-n on the Mac)
|
|
Return while cursor is on a previous command retrieves that command.
|
|
Expand word is also useful to reduce typing.
|
|
|
|
Syntax colors:
|
|
|
|
The coloring is applied in a background "thread", so you may
|
|
occasionally see uncolorized text. To change the color
|
|
scheme, use the Configure IDLE / Highlighting dialog.
|
|
|
|
Python default syntax colors:
|
|
|
|
Keywords orange
|
|
Builtins royal purple
|
|
Strings green
|
|
Comments red
|
|
Definitions blue
|
|
|
|
Shell default colors:
|
|
|
|
Console output brown
|
|
stdout blue
|
|
stderr red
|
|
stdin black
|
|
|
|
Other preferences:
|
|
|
|
The font preferences, keybinding, and startup preferences can
|
|
be changed using the Settings dialog.
|
|
|
|
Command line usage:
|
|
|
|
Enter idle -h at the command prompt to get a usage message.
|
|
|
|
Running without a subprocess:
|
|
|
|
If IDLE is started with the -n command line switch it will run in a
|
|
single process and will not create the subprocess which runs the RPC
|
|
Python execution server. This can be useful if Python cannot create
|
|
the subprocess or the RPC socket interface on your platform. However,
|
|
in this mode user code is not isolated from IDLE itself. Also, the
|
|
environment is not restarted when Run/Run Module (F5) is selected. If
|
|
your code has been modified, you must reload() the affected modules and
|
|
re-import any specific items (e.g. from foo import baz) if the changes
|
|
are to take effect. For these reasons, it is preferable to run IDLE
|
|
with the default subprocess if at all possible.
|
|
|
|
Extensions:
|
|
|
|
IDLE contains an extension facility. See the beginning of
|
|
config-extensions.def in the idlelib directory for further information.
|
|
The default extensions are currently:
|
|
|
|
FormatParagraph
|
|
AutoExpand
|
|
ZoomHeight
|
|
ScriptBinding
|
|
CallTips
|
|
ParenMatch
