Guido van Rossum, as well as being the creator of the Python language, is the
original creator of IDLE.  Other contributors prior to Version 0.8 include
Mark Hammond, Jeremy Hylton, Tim Peters, and Moshe Zadka.

IDLE's recent development was carried out in the SF IDLEfork project. The
objective was to develop a version of IDLE which had an execution environment
which could be initialized prior to each run of user code.

The IDLEfork project was initiated by David Scherer, with some help from Peter
Schneider-Kamp and Nicholas Riley.  David wrote the first version of the RPC
code and designed a fast turn-around environment for VPython.  Guido developed
the RPC code and Remote Debugger currently integrated in IDLE.  Bruce Sherwood
contributed considerable time testing and suggesting improvements.

Besides David and Guido, the main developers who were active on IDLEfork
are Stephen M. Gava, who implemented the configuration GUI, the new
configuration system, and the About dialog, and Kurt B. Kaiser, who completed
the integration of the RPC and remote debugger, implemented the threaded
subprocess, and made a number of usability enhancements.

Other contributors include Raymond Hettinger, Tony Lownds (Mac integration),
Neal Norwitz (code check and clean-up), Ronald Oussoren (Mac integration),
Noam Raphael (Code Context, Call Tips, many other patches), and Chui Tey (RPC
integration, debugger integration and persistent breakpoints).

Scott David Daniels, Tal Einat, Hernan Foffani, Christos Georgiou,
Jim Jewett, Martin v. L�wis, Jason Orendorff, Guilherme Polo, Josh Robb,
Nigel Rowe, Bruce Sherwood, Jeff Shute, and Weeble have submitted useful
patches.  Thanks, guys!

Writing an IDLE extension
=========================

An IDLE extension can define new key bindings and menu entries for IDLE
edit windows.  There is a simple mechanism to load extensions when IDLE
starts up and to attach them to each edit window. (It is also possible
to make other changes to IDLE, but this must be done by editing the IDLE
source code.)

The list of extensions loaded at startup time is configured by editing
the file config-extensions.def.  See below for details.

An IDLE extension is defined by a class.  Methods of the class define
actions that are invoked by event bindings or menu entries. Class (or
instance) variables define the bindings and menu additions; these are
automatically applied by IDLE when the extension is linked to an edit
window.

An IDLE extension class is instantiated with a single argument,
`editwin', an EditorWindow instance. The extension cannot assume much
about this argument, but it is guaranteed to have the following instance
variables:

    text	a Text instance (a widget)
    io		an IOBinding instance (more about this later)
    flist	the FileList instance (shared by all edit windows)

(There are a few more, but they are rarely useful.)

The extension class must not directly bind Window Manager (e.g. X) events.
Rather, it must define one or more virtual events, e.g. <<zoom-height>>, and
corresponding methods, e.g. zoom_height_event().  The virtual events will be
bound to the corresponding methods, and Window Manager events can then be bound
to the virtual events. (This indirection is done so that the key bindings can
easily be changed, and so that other sources of virtual events can exist, such
as menu entries.)

An extension can define menu entries.  This is done with a class or instance
variable named menudefs; it should be a list of pairs, where each pair is a
menu name (lowercase) and a list of menu entries. Each menu entry is either
None (to insert a separator entry) or a pair of strings (menu_label,
virtual_event).  Here, menu_label is the label of the menu entry, and
virtual_event is the virtual event to be generated when the entry is selected.
An underscore in the menu label is removed; the character following the
underscore is displayed underlined, to indicate the shortcut character (for
Windows).

At the moment, extensions cannot define whole new menus; they must define
entries in existing menus.  Some menus are not present on some windows; such
entry definitions are then ignored, but key bindings are still applied.  (This
should probably be refined in the future.)

Extensions are not required to define menu entries for all the events they
implement.  (They are also not required to create keybindings, but in that
case there must be empty bindings in cofig-extensions.def)

Here is a complete example:

class ZoomHeight:

    menudefs = [
        ('edit', [
            None, # Separator
            ('_Zoom Height', '<<zoom-height>>'),
         ])
    ]

    def __init__(self, editwin):
        self.editwin = editwin

    def zoom_height_event(self, event):
        "...Do what you want here..."

The final piece of the puzzle is the file "config-extensions.def", which is
used to configure the loading of extensions and to establish key (or, more
generally, event) bindings to the virtual events defined in the extensions.

See the comments at the top of config-extensions.def for information.  It's
currently necessary to manually modify that file to change IDLE's extension
loading or extension key bindings.

For further information on binding refer to the Tkinter Resources web page at
python.org and to the Tk Command "bind" man page.
This file, idlelib/help.txt is out-of-date and no longer used by Idle.
It is deprecated and will be removed in the future, possibly in 3.6

[See the end of this file for ** TIPS ** on using IDLE !!]

IDLE is the Python IDE built with the tkinter GUI toolkit.

IDLE has the following features:
-coded in 100% pure Python, using the tkinter GUI toolkit
-cross-platform: works on Windows, Unix, and OS X
-multi-window text editor with multiple undo, Python colorizing, smart indent,
call tips, and many other features
-Python shell window (a.k.a interactive interpreter)
-debugger (not complete, but you can set breakpoints, view and step)

Menus:

IDLE has two window types the Shell window and the Editor window. It is
possible to have multiple editor windows simultaneously. IDLE's
menus dynamically change based on which window is currently selected. Each menu
documented below indicates which window type it is associated with. 

File Menu (Shell and Editor):

        New File         -- Create a new file editing window
        Open...          -- Open an existing file
        Open Module...   -- Open an existing module (searches sys.path)
        Recent Files...  -- Open a list of recent files
        Class Browser    -- Show classes and methods in current file
        Path Browser     -- Show sys.path directories, modules, classes,
                            and methods
        ---
        Save             -- Save current window to the associated file (unsaved
                            windows have a * before and after the window title)

        Save As...       -- Save current window to new file, which becomes
                            the associated file
        Save Copy As...  -- Save current window to different file
                            without changing the associated file
        ---
        Print Window     -- Print the current window
        ---
        Close            -- Close current window (asks to save if unsaved)
        Exit             -- Close all windows, quit (asks to save if unsaved)

Edit Menu (Shell and Editor):

        Undo             -- Undo last change to current window
                            (a maximum of 1000 changes may be undone)
        Redo             -- Redo last undone change to current window
        ---
        Cut              -- Copy a selection into system-wide clipboard,
                            then delete the selection
        Copy             -- Copy selection into system-wide clipboard
        Paste            -- Insert system-wide clipboard into window
        Select All       -- Select the entire contents of the edit buffer
        ---
        Find...          -- Open a search dialog box with many options
        Find Again       -- Repeat last search
        Find Selection   -- Search for the string in the selection
        Find in Files... -- Open a search dialog box for searching files
        Replace...       -- Open a search-and-replace dialog box
        Go to Line       -- Ask for a line number and show that line
        Expand Word      -- Expand the word you have typed to match another
                            word in the same buffer; repeat to get a
                            different expansion
        Show Calltip     -- After an unclosed parenthesis for a function, open
                            a small window with function parameter hints
        Show Parens      -- Highlight the surrounding parenthesis
        Show Completions -- Open a scroll window allowing selection keywords
                            and attributes. (see '*TIPS*', below)

Format Menu (Editor window only):

        Indent Region       -- Shift selected lines right by the indent width
                               (default 4 spaces)

        Comment Out Region  -- Insert ## in front of selected lines
        Uncomment Region    -- Remove leading # or ## from selected lines
        Tabify Region       -- Turns *leading* stretches of spaces into tabs.
                (Note: We recommend using 4 space blocks to indent Python code.)
        Untabify Region     -- Turn *all* tabs into the corrent number of spaces
        Toggle tabs         -- Open a dialog to switch between indenting with
                               spaces and tabs.
        New Indent Width... -- Open a dialog to change indent width.  The
                               accepted default by the Python community is 4
                               spaces.
        Format Paragraph    -- Reformat the current blank-line-separated
                               paragraph. All lines in the paragraph will be
                               formatted to less than 80 columns.
        ---
        Strip trailing whitespace -- Removed any space characters after the end
                                     of the last non-space character

Run Menu (Editor window only):

        Python Shell -- Open or wake up the Python shell window
        ---
        Check Module -- Check the syntax of the module currently open in the
                        Editor window.  If the module has not been saved IDLE
                        will prompt the user to save the code.
        Run Module   -- Restart the shell to clean the environment, then
                        execute the currently open module. If the module has
                        not been saved IDLE will prompt the user to save the
                        code.

Shell Menu (Shell window only):

        View Last Restart -- Scroll the shell window to the last Shell restart
        Restart Shell     -- Restart the shell to clean the environment

Debug Menu (Shell window only):

        Go to File/Line   -- Look around the insert point for a filename
                             and line number, open the file, and show the line.
                             Useful to view the source lines referenced in an

** 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 docs.python.org.  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 keybindings (like Control-c to copy and Control-v to
        paste) may work.  Keybindings are selected in the Configure IDLE
        dialog.

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. Currently tabs are restricted to four spaces due
        to Tcl/Tk limitations.

        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) a tab is typed 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, by default the
        Control-space keys will 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 scroll wheel 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 Editor 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.  Or another option is the delay could
        be set to zero. Another alternative to preventing ACW popups is to
        disable the call tips extension.

Python Shell window:

        Control-c interrupts executing command.
        Control-d sends end-of-file; closes window if typed at >>> prompt.
        Alt-/ expand word is also useful to reduce typing.

    Command history:

        Alt-p retrieves previous command matching what you have typed. On OS X
        use Control-p.
        Alt-n retrieves next. On OS X use Control-n.
        Return while cursor is on a previous command retrieves that command.

    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, highlighting, keys, and general preferences can
        be changed via the Configure IDLE menu option.  Be sure to note that
        keys can be user defined, IDLE ships with four built in key sets. In
        addition a user can create a custom key set in the Configure IDLE
        dialog under the keys tab.

Command line usage:

        Enter idle -h at the command prompt to get a usage message.

        idle.py [-c command] [-d] [-e] [-s] [-t title] [arg] ...

        -c command  run this command
        -d          enable debugger
        -e          edit mode; arguments are files to be edited
        -s          run $IDLESTARTUP or $PYTHONSTARTUP first
        -t title    set title of shell window

        If there are arguments:
        1. If -e is used, arguments are files opened for editing and sys.argv
           reflects the arguments passed to IDLE itself.
        2. Otherwise, if -c is used, all arguments are placed in
           sys.argv[1:...], with sys.argv[0] set to -c.
        3. Otherwise, if neither -e nor -c is used, the first argument is a
           script which is executed with the remaining arguments in
           sys.argv[1:...]  and sys.argv[0] set to the script name.  If the
           script name is -, no script is executed but an interactive Python
           session is started; the arguments are still available in sys.argv.

Running without a subprocess: (DEPRECATED in Python 3.4 see Issue 16123)

        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
                AutoComplete
                CodeContext
IDLE History
============

This file contains the release messages for previous IDLE releases.
As you read on you go back to the dark ages of IDLE's history.


What's New in IDLEfork 0.8.1?
=============================

*Release date: 22-Jul-2001*

- New tarball released as a result of the 'revitalisation' of the IDLEfork
  project.

- This release requires python 2.1 or better. Compatibility with earlier
  versions of python (especially ancient ones like 1.5x) is no longer a
  priority in IDLEfork development.

- This release is based on a merging of the earlier IDLE fork work with current
  cvs IDLE (post IDLE version 0.8), with some minor additional coding by Kurt
  B. Kaiser and Stephen M. Gava.

- This release is basically functional but also contains some known breakages,
  particularly with running things from the shell window. Also the debugger is
  not working, but I believe this was the case with the previous IDLE fork
  release (0.7.1) as well.

- This release is being made now to mark the point at which IDLEfork is
  launching into a new stage of development.

- IDLEfork CVS will now be branched to enable further development and
  exploration of the two "execution in a remote process" patches submitted by
  David Scherer (David's is currently in IDLEfork) and GvR, while stabilisation
  and development of less heavyweight improvements (like user customisation)
  can continue on the trunk.


What's New in IDLEfork 0.7.1?
==============================

*Release date: 15-Aug-2000*

- First project tarball released.

- This was the first release of IDLE fork, which at this stage was a
  combination of IDLE 0.5 and the VPython idle fork, with additional changes
  coded by David Scherer, Peter Schneider-Kamp and Nicholas Riley.



IDLEfork 0.7.1 - 29 May 2000
-----------------------------

   David Scherer  <dscherer@cmu.edu>

- This is a modification of the CVS version of IDLE 0.5, updated as of
  2000-03-09.  It is alpha software and might be unstable.  If it breaks, you
  get to keep both pieces.

- If you have problems or suggestions, you should either contact me or post to
  the list at http://www.python.org/mailman/listinfo/idle-dev (making it clear
  that you are using this modified version of IDLE).

- Changes:

  - The ExecBinding module, a replacement for ScriptBinding, executes programs
    in a separate process, piping standard I/O through an RPC mechanism to an
    OnDemandOutputWindow in IDLE.  It supports executing unnamed programs
    (through a temporary file).  It does not yet support debugging.

  - When running programs with ExecBinding, tracebacks will be clipped to
    exclude system modules.  If, however, a system module calls back into the
    user program, that part of the traceback will be shown.

  - The OnDemandOutputWindow class has been improved.  In particular, it now
    supports a readline() function used to implement user input, and a
    scroll_clear() operation which is used to hide the output of a previous run
    by scrolling it out of the window.

  - Startup behavior has been changed.  By default IDLE starts up with just a
    blank editor window, rather than an interactive window.  Opening a file in
    such a blank window replaces the (nonexistent) contents of that window
    instead of creating another window.  Because of the need to have a
    well-known port for the ExecBinding protocol, only one copy of IDLE can be
    running.  Additional invocations use the RPC mechanism to report their
    command line arguments to the copy already running.

  - The menus have been reorganized.  In particular, the excessively large
    'edit' menu has been split up into 'edit', 'format', and 'run'.

  - 'Python Documentation' now works on Windows, if the win32api module is
    present.

  - A few key bindings have been changed: F1 now loads Python Documentation
    instead of the IDLE help; shift-TAB is now a synonym for unindent.

- New modules:

  ExecBinding.py         Executes program through loader
  loader.py              Bootstraps user program
  protocol.py            RPC protocol
  Remote.py              User-process interpreter
  spawn.py               OS-specific code to start programs

- Files modified:

  autoindent.py          ( bindings tweaked )
  bindings.py            ( menus reorganized )
  config.txt             ( execbinding enabled )
  editorwindow.py        ( new menus, fixed 'Python Documentation' )
  filelist.py            ( hook for "open in same window" )
  formatparagraph.py     ( bindings tweaked )
  idle.bat               ( removed absolute pathname )
  idle.pyw               ( weird bug due to import with same name? )
  iobinding.py           ( open in same window, EOL convention )
  keydefs.py             ( bindings tweaked )
  outputwindow.py        ( readline, scroll_clear, etc )
  pyshell.py             ( changed startup behavior )
  readme.txt             ( <Recursion on file with id=1234567> )



IDLE 0.5 - February 2000 - Release Notes
----------------------------------------

This is an early release of IDLE, my own attempt at a Tkinter-based
IDE for Python.

(For a more detailed change log, see the file ChangeLog.)

FEATURES

IDLE has the following features:

- coded in 100% pure Python, using the Tkinter GUI toolkit (i.e. Tcl/Tk)

- cross-platform: works on Windows and Unix (on the Mac, there are
currently problems with Tcl/Tk)

- multi-window text editor with multiple undo, Python colorizing
and many other features, e.g. smart indent and call tips

- Python shell window (a.k.a. interactive interpreter)

- debugger (not complete, but you can set breakpoints, view  and step)

USAGE

The main program is in the file "idle.py"; on Unix, you should be able
to run it by typing "./idle.py" to your shell.  On Windows, you can
run it by double-clicking it; you can use idle.pyw to avoid popping up
a DOS console.  If you want to pass command line arguments on Windows,
use the batch file idle.bat.

Command line arguments: files passed on the command line are executed,
not opened for editing, unless you give the -e command line option.
Try "./idle.py -h" to see other command line options.

IDLE requires Python 1.5.2, so it is currently only usable with a
Python 1.5.2 distribution.  (An older version of IDLE is distributed
with Python 1.5.2; you can drop this version on top of it.)

COPYRIGHT

IDLE is covered by the standard Python copyright notice
(http://www.python.org/doc/Copyright.html).


New in IDLE 0.5 (2/15/2000)
---------------------------

Tons of stuff, much of it contributed by Tim Peters and Mark Hammond:

- Status bar, displaying current line/column (Moshe Zadka).

- Better stack viewer, using tree widget.  (XXX Only used by Stack
Viewer menu, not by the debugger.)

- Format paragraph now recognizes Python block comments and reformats
them correctly (MH)

- New version of pyclbr.py parses top-level functions and understands
much more of Python's syntax; this is reflected in the class and path
browsers (TP)

- Much better auto-indent; knows how to indent the insides of
multi-line statements (TP)

- Call tip window pops up when you type the name of a known function
followed by an open parenthesis.  Hit ESC or click elsewhere in the
window to close the tip window (MH)

- Comment out region now inserts ## to make it stand out more (TP)

- New path and class browsers based on a tree widget that looks
familiar to Windows users

- Reworked script running commands to be more intuitive: I/O now
always goes to the *Python Shell* window, and raw_input() works
correctly.  You use F5 to import/reload a module: this adds the module
name to the __main__ namespace.  You use Control-F5 to run a script:
this runs the script *in* the __main__ namespace.  The latter also
sets sys.argv[] to the script name


New in IDLE 0.4 (4/7/99)
------------------------

Most important change: a new menu entry "File -> Path browser", shows
a 4-column hierarchical browser which lets you browse sys.path,
directories, modules, and classes.  Yes, it's a superset of the Class
browser menu entry.  There's also a new internal module,
MultiScrolledLists.py, which provides the framework for this dialog.


New in IDLE 0.3 (2/17/99)
-------------------------

Most important changes:

- Enabled support for running a module, with or without the debugger.
Output goes to a new window.  Pressing F5 in a module is effectively a
reload of that module; Control-F5 loads it under the debugger.

- Re-enable tearing off the Windows menu, and make a torn-off Windows
menu update itself whenever a window is opened or closed.

- Menu items can now be have a checkbox (when the menu label starts
with "!"); use this for the Debugger and "Auto-open stack viewer"
(was: JIT stack viewer) menu items.

- Added a Quit button to the Debugger API.

- The current directory is explicitly inserted into sys.path.

- Fix the debugger (when using Python 1.5.2b2) to use canonical
filenames for breakpoints, so these actually work.  (There's still a
lot of work to be done to the management of breakpoints in the
debugger though.)

- Closing a window that is still colorizing now actually works.

- Allow dragging of the separator between the two list boxes in the
class browser.

- Bind ESC to "close window" of the debugger, stack viewer and class
browser.  It removes the selection highlighting in regular text
windows.  (These are standard Windows conventions.)


New in IDLE 0.2 (1/8/99)
------------------------

Lots of changes; here are the highlights:

General:

- You can now write and configure your own IDLE extension modules; see
extend.txt.


File menu:

The command to open the Python shell window is now in the File menu.


Edit menu:

New Find dialog with more options; replace dialog; find in files dialog.

Commands to tabify or untabify a region.

Command to format a paragraph.


Debug menu:

JIT (Just-In-Time) stack viewer toggle -- if set, the stack viewer
automaticall pops up when you get a traceback.

Windows menu:

Zoom height -- make the window full height.


Help menu:

The help text now show up in a regular window so you can search and
even edit it if you like.



IDLE 0.1 was distributed with the Python 1.5.2b1 release on 12/22/98.

======================================================================
README FOR IDLE TESTS IN IDLELIB.IDLE_TEST

0. Quick Start

Automated unit tests were added in 2.7 for Python 2.x and 3.3 for Python 3.x.
To run the tests from a command line:

python -m test.test_idle

Human-mediated tests were added later in 2.7 and in 3.4.

python -m idlelib.idle_test.htest


1. Test Files

The idle directory, idlelib, has over 60 xyz.py files. The idle_test
subdirectory should contain a test_xyz.py for each, where 'xyz' is lowercased
even if xyz.py is not. Here is a possible template, with the blanks after after
'.' and 'as', and before and after '_' to be filled in.

import unittest
from test.support import requires
import idlelib. as

class _Test(unittest.TestCase):

    def test_(self):

if __name__ == '__main__':
    unittest.main(verbosity=2)

Add the following at the end of xyy.py, with the appropriate name added after
'test_'. Some files already have something like this for htest.  If so, insert
the import and unittest.main lines before the htest lines.

if __name__ == "__main__":
    import unittest
    unittest.main('idlelib.idle_test.test_', verbosity=2, exit=False)



2. GUI Tests

When run as part of the Python test suite, Idle gui tests need to run
test.support.requires('gui') (test.test_support in 2.7).  A test is a gui test
if it creates a Tk root or master object either directly or indirectly by
instantiating a tkinter or idle class.  For the benefit of test processes that
either have no graphical environment available or are not allowed to use it, gui
tests must be 'guarded' by "requires('gui')" in a setUp function or method.
This will typically be setUpClass.

To avoid interfering with other gui tests, all gui objects must be destroyed and
deleted by the end of the test.  Widgets, such as a Tk root, created in a setUpX
function, should be destroyed in the corresponding tearDownX.  Module and class
widget attributes should also be deleted..

    @classmethod
    def setUpClass(cls):
        requires('gui')
        cls.root = tk.Tk()

    @classmethod
    def tearDownClass(cls):
        cls.root.destroy()
        del cls.root


Requires('gui') causes the test(s) it guards to be skipped if any of
a few conditions are met:
    
 - The tests are being run by regrtest.py, and it was started without enabling
   the "gui" resource with the "-u" command line option.
   
 - The tests are being run on Windows by a service that is not allowed to
   interact with the graphical environment.
   
 - The tests are being run on Mac OSX in a process that cannot make a window
   manager connection.
   
 - tkinter.Tk cannot be successfully instantiated for some reason.
 
 - test.support.use_resources has been set by something other than
   regrtest.py and does not contain "gui".
   
Tests of non-gui operations should avoid creating tk widgets. Incidental uses of
tk variables and messageboxes can be replaced by the mock classes in
idle_test/mock_tk.py. The mock text handles some uses of the tk Text widget.


3. Running Unit Tests

Assume that xyz.py and test_xyz.py both end with a unittest.main() call.
Running either from an Idle editor runs all tests in the test_xyz file with the
version of Python running Idle.  Test output appears in the Shell window.  The
'verbosity=2' option lists all test methods in the file, which is appropriate
when developing tests. The 'exit=False' option is needed in xyx.py files when an
htest follows.

The following command lines also run all test methods, including
gui tests, in test_xyz.py. (Both '-m idlelib' and '-m idlelib.idle' start
Idle and so cannot run tests.)

python -m idlelib.xyz
python -m idlelib.idle_test.test_xyz

The following runs all idle_test/test_*.py tests interactively.

>>> import unittest
>>> unittest.main('idlelib.idle_test', verbosity=2)

The following run all Idle tests at a command line.  Option '-v' is the same as
'verbosity=2'.  (For 2.7, replace 'test' in the second line with
'test.regrtest'.)

python -m unittest -v idlelib.idle_test
python -m test -v -ugui test_idle
python -m test.test_idle

The idle tests are 'discovered' by idlelib.idle_test.__init__.load_tests,
which is also imported into test.test_idle. Normally, neither file should be
changed when working on individual test modules. The third command runs
unittest indirectly through regrtest. The same happens when the entire test
suite is run with 'python -m test'. So that command must work for buildbots
to stay green. Idle tests must not disturb the environment in a way that
makes other tests fail (issue 18081).

To run an individual Testcase or test method, extend the dotted name given to
unittest on the command line.

python -m unittest -v idlelib.idle_test.test_xyz.Test_case.test_meth


4. Human-mediated Tests

Human-mediated tests are widget tests that cannot be automated but need human
verification. They are contained in idlelib/idle_test/htest.py, which has
instructions.  (Some modules need an auxiliary function, identified with # htest
# on the header line.)  The set is about complete, though some tests need
improvement. To run all htests, run the htest file from an editor or from the
command line with:

python -m idlelib.idle_test.htest
What's New in IDLE 3.5.1?
=========================
*Release date: 2015-12-06*

- Issue 15348: Stop the debugger engine (normally in a user process)
  before closing the debugger window (running in the IDLE process).
  This prevents the RuntimeErrors that were being caught and ignored.

- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
  debugger is active (15347); b) closing the debugger with the [X] button
  (15348); and c) activating the debugger when already active (24455).
  The patch by Mark Roseman does this by making two changes.
  1. Suspend and resume the gui.interaction method with the tcl vwait
  mechanism intended for this purpose (instead of root.mainloop & .quit).
  2. In gui.run, allow any existing interaction to terminate first.

- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
  to make it clearer that the program referred to is the currently running
  user program, not IDLE itself.

- Issue #24750: Improve the appearance of the IDLE editor window status bar.
  Patch by Mark Roseman.

- Issue #25313: Change the handling of new built-in text color themes to better
  address the compatibility problem introduced by the addition of IDLE Dark.
  Consistently use the revised idleConf.CurrentTheme everywhere in idlelib.

- Issue #24782: Extension configuration is now a tab in the IDLE Preferences
  dialog rather than a separate dialog.   The former tabs are now a sorted
  list.  Patch by Mark Roseman.

- Issue #22726: Re-activate the config dialog help button with some content
  about the other buttons and the new IDLE Dark theme.

- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
  It is more or less IDLE Classic inverted, with a cobalt blue background.
  Strings, comments, keywords, ... are still green, red, orange, ... .
  To use it with IDLEs released before November 2015, hit the
  'Save as New Custom Theme' button and enter a new name,
  such as 'Custom Dark'.  The custom theme will work with any IDLE
  release, and can be modified.

- Issue #25224: README.txt is now an idlelib index for IDLE developers and
  curious users.  The previous user content is now in the IDLE doc chapter.
  'IDLE' now means 'Integrated Development and Learning Environment'.

- Issue #24820: Users can now set breakpoint colors in
  Settings -> Custom Highlighting.  Original patch by Mark Roseman.

- Issue #24972: Inactive selection background now matches active selection
  background, as configured by users, on all systems.  Found items are now
  always highlighted on Windows.  Initial patch by Mark Roseman.

- Issue #24570: Idle: make calltip and completion boxes appear on Macs
  affected by a tk regression.  Initial patch by Mark Roseman.

- Issue #24988: Idle ScrolledList context menus (used in debugger)
  now work on Mac Aqua.  Patch by Mark Roseman.

- Issue #24801: Make right-click for context menu work on Mac Aqua.
  Patch by Mark Roseman.

- Issue #25173: Associate tkinter messageboxes with a specific widget.
  For Mac OSX, make them a 'sheet'.  Patch by Mark Roseman.

- Issue #25198: Enhance the initial html viewer now used for Idle Help.
  * Properly indent fixed-pitch text (patch by Mark Roseman).
  * Give code snippet a very Sphinx-like light blueish-gray background.
  * Re-use initial width and height set by users for shell and editor.
  * When the Table of Contents (TOC) menu is used, put the section header
  at the top of the screen.

- Issue #25225: Condense and rewrite Idle doc section on text colors.

- Issue #21995: Explain some differences between IDLE and console Python.

- Issue #22820: Explain need for *print* when running file from Idle editor.

- Issue #25224: Doc: augment Idle feature list and no-subprocess section.

- Issue #25219: Update doc for Idle command line options.
  Some were missing and notes were not correct.

- Issue #24861: Most of idlelib is private and subject to change.
  Use idleib.idle.* to start Idle. See idlelib.__init__.__doc__.

- Issue #25199: Idle: add synchronization comments for future maintainers.

- Issue #16893: Replace help.txt with help.html for Idle doc display.
  The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.
  It looks better than help.txt and will better document Idle as released.
  The tkinter html viewer that works for this file was written by Mark Roseman.
  The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.

- Issue #24199: Deprecate unused idlelib.idlever with possible removal in 3.6.

- Issue #24790: Remove extraneous code (which also create 2 & 3 conflicts).


What's New in IDLE 3.5.0?
=========================
*Release date: 2015-09-13*

- Issue #23672: Allow Idle to edit and run files with astral chars in name.
  Patch by Mohd Sanad Zaki Rizvi.

- Issue 24745: Idle editor default font. Switch from Courier to
  platform-sensitive TkFixedFont.  This should not affect current customized
  font selections.  If there is a problem, edit $HOME/.idlerc/config-main.cfg
  and remove 'fontxxx' entries from [Editor Window].  Patch by Mark Roseman.

- Issue #21192: Idle editor. When a file is run, put its name in the restart bar.
  Do not print false prompts. Original patch by Adnan Umer.

- Issue #13884: Idle menus. Remove tearoff lines. Patch by Roger Serwy.

- Issue #23184: remove unused names and imports in idlelib.
  Initial patch by Al Sweigart.

  extension has been moved from the General tab of the Idle preferences dialog
  to the FormatParagraph tab of the Config Extensions dialog.
  Patch by Tal Einat.

- Issue #16893: Update Idle doc chapter to match current Idle and add new
  information.

- Issue #3068: Add Idle extension configuration dialog to Options menu.
  Changes are written to HOME/.idlerc/config-extensions.cfg.
  Original patch by Tal Einat.

- Issue #16233: A module browser (File : Class Browser, Alt+C) requires a
  editor window with a filename.  When Class Browser is requested otherwise,
  from a shell, output window, or 'Untitled' editor, Idle no longer displays
  an error box.  It now pops up an  Open Module box (Alt+M). If a valid name
  is entered and a module is opened, a corresponding browser is also opened.

- Issue #4832: Save As to type Python files automatically adds .py to the
  name you enter (even if your system does not display it).  Some systems
  automatically add .txt when type is Text files.

- Issue #21986: Code objects are not normally pickled by the pickle module.
  To match this, they are no longer pickled when running under Idle.

- Issue #21695: Closing a Find-in-files output window while the search is
  still in progress no longer closes Idle.

- Issue #18910: Add unittest for textView. Patch by Phil Webster.

- Issue #18292: Add unittest for AutoExpand. Patch by Saihadhav Heblikar.

- Issue #18409: Add unittest for AutoComplete. Patch by Phil Webster.

  Patches by Saimadhav Heblikar

- Issue #18104: Add idlelib/idle_test/htest.py with a few sample tests to begin
  consolidating and improving human-validated tests of Idle. Change other files
  as needed to work with htest.  Running the module as __main__ runs all tests.

- Issue #21139: Change default paragraph width to 72, the PEP 8 recommendation.

- Issue #21284: Paragraph reformat test passes after user changes reformat width.

- Issue #17654: Ensure IDLE menus are customized properly on OS X for

- Issue #3573: IDLE hangs when passing invalid command line args
  (directory(ies) instead of file(s)).

- Issue #14018: Update checks for unstable system Tcl/Tk versions on OS X

  behavior. Issue 4676.  Improve selection extension behaviour.

- <Home> toggle non-functional when NumLock set on Windows.  Issue 3851.

What's New in IDLE 2.6
======================
*Release date: 01-Oct-2008*, merged into 3.0 releases detailed above (3.0rc2)

- Issue #2665: On Windows, an IDLE installation upgraded from an old version
  would not start if a custom theme was defined.

- Home / Control-A toggles between left margin and end of leading white
  space.  issue1196903, patch by Jeff Shute.

- Improved AutoCompleteWindow logic.  issue2062, patch by Tal Einat.

- Autocompletion of filenames now support alternate separators, e.g. the
  '/' char on Windows.  issue2061 Patch by Tal Einat.

- Configured selection highlighting colors were ignored; updating highlighting
  in the config dialog would cause non-Python files to be colored as if they
  were Python source; improve use of ColorDelagator.  Patch 1334. Tal Einat.

- ScriptBinding event handlers weren't returning 'break'. Patch 2050, Tal Einat

- There was an error on exit if no sys.exitfunc was defined. Issue 1647.

  option in config-extensions w/o a value. Patch #1672481, Tal Einat

- Corrected some bugs in AutoComplete.  Also, Page Up/Down in ACW implemented;
  mouse and cursor selection in ACWindow implemented; double Tab inserts
  current selection and closes ACW (similar to double-click and Return); scroll
  wheel now works in ACW.  Added AutoComplete instructions to IDLE Help.

- AutoCompleteWindow moved below input line, will move above if there
  isn't enough space.  Patch 1621265 Tal Einat

- Calltips now 'handle' tuples in the argument list (display '<tuple>' :)
  Suggested solution by Christos Georgiou, Bug 791968.

- Add 'raw' support to configHandler. Patch 1650174 Tal Einat.

- Avoid hang when encountering a duplicate in a completion list. Bug 1571112.

- Patch #1362975: Rework CodeContext indentation algorithm to
  avoid hard-coding pixel widths.

- Bug #813342: Start the IDLE subprocess with -Qnew if the parent
  is started with that option.

- Honor the "Cancel" action in the save dialog (Debian bug #299092)

- Some syntax errors were being caught by tokenize during the tabnanny
  check, resulting in obscure error messages.  Do the syntax check
  first.  Bug 1562716, 1562719

- IDLE's version number takes a big jump to match the version number of
  the Python release of which it's a part.


What's New in IDLE 1.2?
=======================
*Release date: 19-SEP-2006*

- File menu hotkeys: there were three 'p' assignments.  Reassign the
  'Save Copy As' and 'Print' hotkeys to 'y' and 't'.  Change the
  Shell hotkey from 's' to 'l'.

- IDLE honors new quit() and exit() commands from site.py Quitter() object.
  Patch 1540892, Jim Jewett

- The 'with' statement is now a Code Context block opener.
  Patch 1540851, Jim Jewett

- Retrieval of previous shell command was not always preserving indentation
  (since 1.2a1) Patch 1528468 Tal Einat.

- Changing tokenize (39046) to detect dedent broke tabnanny check (since 1.2a1)

- ToggleTab dialog was setting indent to 8 even if cancelled (since 1.2a1).

- When used w/o subprocess, all exceptions were preceded by an error
  message claiming they were IDLE internal errors (since 1.2a1).

- Bug #1525817: Don't truncate short lines in IDLE's tool tips.

- Bug #1517990: IDLE keybindings on MacOS X now work correctly

- Bug #1517996: IDLE now longer shows the default Tk menu when a
  path browser, class browser or debugger is the frontmost window on MacOS X

- EditorWindow.test() was failing.  Bug 1417598

- EditorWindow failed when used stand-alone if sys.ps1 not set.
  Bug 1010370 Dave Florek

- Tooltips failed on new-syle class __init__ args.  Bug 1027566 Loren Guthrie

- Avoid occasional failure to detect closing paren properly.
  Patch 1407280 Tal Einat

- Rebinding Tab key was inserting 'tab' instead of 'Tab'.  Bug 1179168.

- Colorizer now handles #<builtin> correctly, also unicode strings and
  'as' keyword in comment directly following import command. Closes 1325071.
  Patch 1479219 Tal Einat

- Patch #1162825: Support non-ASCII characters in IDLE window titles.

- Source file f.flush() after writing; trying to avoid lossage if user
  kills GUI.

- Options / Keys / Advanced dialog made functional.  Also, allow binding
  of 'movement' keys.

- 'syntax' patch adds improved calltips and a new class attribute listbox.
  MultiCall module allows binding multiple actions to an event.
  Patch 906702 Noam Raphael

- Better indentation after first line of string continuation.
  IDLEfork Patch 681992, Noam Raphael

- Fixed CodeContext alignment problem, following suggestion from Tal Einat.

- Increased performance in CodeContext extension  Patch 936169 Noam Raphael

- Mac line endings were incorrect when pasting code from some browsers
  when using X11 and the Fink distribution.  Python Bug 1263656.

- <Enter> when cursor is on a previous command retrieves that command.  Instead
  of replacing the input line, the previous command is now appended to the
  input line. Indentation is preserved, and undo is enabled.
  Patch 1196917  Jeff Shute

- Clarify "tab/space" Error Dialog and "Tab Width" Dialog associated with
  the Untabify command.

- Corrected "tab/space" Error Dialog to show correct menu for Untabify.
  Patch 1196980 Jeff Shute

- New files are colorized by default, and colorizing is removed when
  saving as non-Python files. Patch 1196895 Jeff Shute
  Closes Python Bugs 775012 and 800432, partial fix IDLEfork 763524

- Improve subprocess link error notification.

- run.py: use Queue's blocking feature instead of sleeping in the main
  loop.  Patch # 1190163 Michiel de Hoon

- Add config-main option to make the 'history' feature non-cyclic.
  Default remains cyclic.  Python Patch 914546 Noam Raphael.

- Removed ability to configure tabs indent from Options dialog.  This 'feature'
  has never worked and no one has complained.  It is still possible to set a
  default tabs (v. spaces) indent 'manually' via config-main.def (or to turn on
  tabs for the current EditorWindow via the Format menu) but IDLE will
  encourage indentation via spaces.

- Enable setting the indentation width using the Options dialog.
  Bug # 783877

- Add keybindings for del-word-left and del-word-right.

- Discourage using an indent width other than 8 when using tabs to indent
  Python code.

- Restore use of EditorWindow.set_indentation_params(), was dead code since
  Autoindent was merged into EditorWindow.  This allows IDLE to conform to the
  indentation width of a loaded file.  (But it still will not switch to tabs
  even if the file uses tabs.)  Any change in indent width is local to that
  window.

- Add Tabnanny check before Run/F5, not just when Checking module.

- If an extension can't be loaded, print warning and skip it instead of
  erroring out.

- Improve error handling when .idlerc can't be created (warn and exit).

- The GUI was hanging if the shell window was closed while a raw_input()
  was pending.  Restored the quit() of the readline() mainloop().
  http://mail.python.org/pipermail/idle-dev/2004-December/002307.html

- The remote procedure call module rpc.py can now access data attributes of
  remote registered objects.  Changes to these attributes are local, however.


What's New in IDLE 1.1?
=======================
*Release date: 30-NOV-2004*

- On OpenBSD, terminating IDLE with ctrl-c from the command line caused a
  stuck subprocess MainThread because only the SocketThread was exiting.

- Saving a Keyset w/o making changes (by using the "Save as New Custom Key Set"
  button) caused IDLE to fail on restart (no new keyset was created in
  config-keys.cfg).  Also true for Theme/highlights.  Python Bug 1064535.

- A change to the linecache.py API caused IDLE to exit when an exception was
  raised while running without the subprocess (-n switch).  Python Bug 1063840.

- When paragraph reformat width was made configurable, a bug was
  introduced that caused reformatting of comment blocks to ignore how
  far the block was indented, effectively adding the indentation width
  to the reformat width.  This has been repaired, and the reformat
  width is again a bound on the total width of reformatted lines.

- Improve keyboard focus binding, especially in Windows menu.  Improve
  window raising, especially in the Windows menu and in the debugger.
  IDLEfork 763524.

- If user passes a non-existent filename on the commandline, just
  open a new file, don't raise a dialog.  IDLEfork 854928.

- EditorWindow.py was not finding the .chm help file on Windows.  Typo
  at Rev 1.54.  Python Bug 990954

- checking sys.platform for substring 'win' was breaking IDLE docs on Mac
  (darwin).  Also, Mac Safari browser requires full file:// URIs.  SF 900580.

- Redirect the warning stream to the shell during the ScriptBinding check of
  user code and format the warning similarly to an exception for both that
  check and for runtime warnings raised in the subprocess.

- CodeContext hint pane visibility state is now persistent across sessions.
  The pane no longer appears in the shell window.  Added capability to limit
  extensions to shell window or editor windows.  Noam Raphael addition
  to Patch 936169.

- Paragraph reformat width is now a configurable parameter in the
  Options GUI.

- New Extension: CodeContext.  Provides block structuring hints for code
  which has scrolled above an edit window. Patch 936169 Noam Raphael.

- If nulls somehow got into the strings in recent-files.lst
  EditorWindow.update_recent_files_list() was failing.  Python Bug 931336.

- If the normal background is changed via Configure/Highlighting, it will
  update immediately, thanks to the previously mentioned patch by Nigel Rowe.

- Add a highlight theme for builtin keywords.  Python Patch 805830 Nigel Rowe
  This also fixed IDLEfork bug [ 693418 ] Normal text background color not
  refreshed and Python bug [897872 ] Unknown color name on HP-UX

- rpc.py:SocketIO - Large modules were generating large pickles when downloaded
  to the execution server.  The return of the OK response from the subprocess
  initialization was interfering and causing the sending socket to be not
  ready.  Add an IO ready test to fix this.  Moved the polling IO ready test
  into pollpacket().

- Fix typo in rpc.py, s/b "pickle.PicklingError" not "pickle.UnpicklingError".

- Added a Tk error dialog to run.py inform the user if the subprocess can't
  connect to the user GUI process.  Added a timeout to the GUI's listening
  socket.  Added Tk error dialogs to PyShell.py to announce a failure to bind
  the port or connect to the subprocess.  Clean up error handling during
  connection initiation phase.  This is an update of Python Patch 778323.

- Print correct exception even if source file changed since shell was
  restarted.  IDLEfork Patch 869012 Noam Raphael

- Keybindings with the Shift modifier now work correctly.  So do bindings which
  use the Space key.  Limit unmodified user keybindings to the function keys.
  Python Bug 775353, IDLEfork Bugs 755647, 761557

- After an exception, run.py was not setting the exception vector. Noam
  Raphael suggested correcting this so pdb's postmortem pm() would work.
  IDLEfork Patch 844675

- IDLE now does not fail to save the file anymore if the Tk buffer is not a
  Unicode string, yet eol_convention is.  Python Bugs 774680, 788378

- IDLE didn't start correctly when Python was installed in "Program Files" on
  W2K and XP.  Python Bugs 780451, 784183

- config-main.def documentation incorrectly referred to idle- instead of
  config-  filenames.  SF 782759  Also added note about .idlerc location.


What's New in IDLE 1.0?
=======================
*Release date: 29-Jul-2003*

- Added a banner to the shell discussing warnings possibly raised by personal
  firewall software.  Added same comment to README.txt.

- Calltip error when docstring was None  Python Bug 775541

- Updated extend.txt, help.txt, and config-extensions.def to correctly
  reflect the current status of the configuration system.  Python Bug 768469

- Fixed: Call Tip Trimming May Loop Forever. Python Patch 769142 (Daniels)

- Replaced apply(f, args, kwds) with f(*args, **kwargs) to improve performance
  Python Patch 768187

- Break or continue statements outside a loop were causing IDLE crash
  Python Bug 767794

- Convert Unicode strings from readline to IOBinding.encoding.  Also set
  sys.std{in|out|err}.encoding, for both the local and the subprocess case.
  SF IDLEfork patch 682347.

- Extend AboutDialog.ViewFile() to support file encodings.  Make the CREDITS
  file Latin-1.

- Updated the About dialog to reflect re-integration into Python.  Provide
  buttons to display Python's NEWS, License, and Credits, plus additional
  buttons for IDLE's README and NEWS.

- TextViewer() now has a third parameter which allows inserting text into the
  viewer instead of reading from a file.

- (Created the .../Lib/idlelib directory in the Python CVS, which is a clone of
  IDLEfork modified to install in the Python environment.  The code in the
  interrupt module has been moved to thread.interrupt_main(). )

- Printing the Shell window was failing if it was not saved first SF 748975

- When using the Search in Files dialog, if the user had a selection
  highlighted in his Editor window, insert it into the dialog search field.

- The Python Shell entry was disappearing from the Windows menu.

- Update the Windows file list when a file name change occurs

- Change to File / Open Module: always pop up the dialog, using the current
  selection as the default value.  This is easier to use habitually.

- Avoided a problem with starting the subprocess when 'localhost' doesn't
  resolve to the user's loopback interface.  SF 747772

- Fixed an issue with highlighted errors never de-colorizing.  SF 747677.  Also
  improved notification of Tabnanny Token Error.

- File / New will by default save in the directory of the Edit window from
  which it was initiated.  SF 748973 Guido van Rossum patch.


What's New in IDLEfork 0.9b1?
=============================
*Release date: 02-Jun-2003*

- The current working directory of the execution environment (and shell
  following completion of execution) is now that of the module being run.

- Added the delete-exitfunc option to config-main.def.  (This option is not
  included in the Options dialog.)  Setting this to True (the default) will
  cause IDLE to not run sys.exitfunc/atexit when the subprocess exits.

- IDLE now preserves the line ending codes when editing a file produced on
  a different platform. SF 661759,  SF 538584

- Reduced default editor font size to 10 point and increased window height
  to provide a better initial impression on Windows.

- Options / Fonts/Tabs / Set Base Editor Font: List box was not highlighting
  the default font when first installed on Windows.  SF 661676

- Added Autosave feature: when user runs code from edit window, if the file
  has been modified IDLE will silently save it if Autosave is enabled.  The
  option is set in the Options dialog, and the default is to prompt the
  user to save the file.   SF 661318 Bruce Sherwood patch.

- Improved the RESTART annotation in the shell window when the user restarts
  the shell while it is generating output.  Also improved annotation when user
  repeatedly hammers the Ctrl-F6 restart.

- Allow IDLE to run when not installed and cwd is not the IDLE directory
  SF Patch 686254 "Run IDLEfork from any directory without set-up" - Raphael

- When a module is run from an EditorWindow: if its directory is not in
  sys.path, prepend it.  This allows the module to import other modules in
  the same directory.  Do the same for a script run from the command line.

- Correctly restart the subprocess if it is running user code and the user
  attempts to run some other module or restarts the shell.  Do the same if
  the link is broken and it is possible to restart the subprocess and re-
  connect to the GUI.   SF RFE 661321.

- Improved exception reporting when running commands or scripts from the
  command line.

- Added a -n command line switch to start IDLE without the subprocess.
  Removed the Shell menu when running in that mode.  Updated help messages.

- Added a comment to the shell startup header to indicate when IDLE is not
  using the subprocess.

- Restore the ability to run without the subprocess.  This can be important for
  some platforms or configurations.  (Running without the subprocess allows the
  debugger to trace through parts of IDLE itself, which may or may not be
  desirable, depending on your point of view.  In addition, the traditional
  reload/import tricks must be use if user source code is changed.)  This is
  helpful for developing IDLE using IDLE, because one instance can be used to
  edit the code and a separate instance run to test changes.  (Multiple
  concurrent IDLE instances with subprocesses is a future feature)

- Improve the error message a user gets when saving a file with non-ASCII
  characters and no source encoding is specified.  Done by adding a dialog
  'EncodingMessage', which contains the line to add in a fixed-font entry
  widget, and which has a button to add that line to the file automatically.
  Also, add a configuration option 'EditorWindow/encoding', which has three
  possible values: none, utf-8, and locale. None is the default: IDLE will show
  this dialog when non-ASCII characters are encountered. utf-8 means that files
  with non-ASCII characters are saved as utf-8-with-bom. locale means that
  files are saved in the locale's encoding; the dialog is only displayed if the
  source contains characters outside the locale's charset.  SF 710733 - Loewis

- Improved I/O response by tweaking the wait parameter in various
  calls to signal.signal().

- Implemented a threaded subprocess which allows interrupting a pass
  loop in user code using the 'interrupt' extension.  User code runs
  in MainThread, while the RPCServer is handled by SockThread.  This is
  necessary because Windows doesn't support signals.

- Implemented the 'interrupt' extension module, which allows a subthread
  to raise a KeyboardInterrupt in the main thread.

- Attempting to save the shell raised an error related to saving
  breakpoints, which are not implemented in the shell

- Provide a correct message when 'exit' or 'quit' are entered at the
  IDLE command prompt  SF 695861

- Eliminate extra blank line in shell output caused by not flushing
  stdout when user code ends with an unterminated print. SF 695861

- Moved responsibility for exception formatting (i.e. pruning IDLE internal
  calls) out of rpc.py into the client and server.

- Exit IDLE cleanly even when doing subprocess I/O

- Handle subprocess interrupt with an RPC message.

- Restart the subprocess if it terminates itself. (VPython programs do that)

- Support subclassing of exceptions, including in the shell, by moving the
  exception formatting to the subprocess.


What's New in IDLEfork 0.9 Alpha 2?
===================================
*Release date: 27-Jan-2003*

- Updated INSTALL.txt to claify use of the python2 rpm.

- Improved formatting in IDLE Help.

- Run menu: Replace "Run Script" with "Run Module".

- Code encountering an unhandled exception under the debugger now shows
  the correct traceback, with IDLE internal levels pruned out.

- If an exception occurs entirely in IDLE, don't prune the IDLE internal
  modules from the traceback displayed.

- Class Browser and Path Browser now use Alt-Key-2 for vertical zoom.

- IDLE icons will now install correctly even when setup.py is run from the
  build directory

- Class Browser now compatible with Python2.3 version of pyclbr.py

- Left cursor move in presence of selected text now moves from left end
  of the selection.

- Add Meta keybindings to "IDLE Classic Windows" to handle reversed
  Alt/Meta on some Linux distros.

- Change default: IDLE now starts with Python Shell.

- Removed the File Path from the Additional Help Sources scrolled list.

- Add capability to access Additional Help Sources on the web if the
  Help File Path begins with //http or www.  (Otherwise local path is
  validated, as before.)

- Additional Help Sources were not being posted on the Help menu in the
  order entered.  Implement sorting the list by [HelpFiles] 'option'
  number.

- Add Browse button to New Help Source dialog.  Arrange to start in
  Python/Doc if platform is Windows, otherwise start in current directory.

- Put the Additional Help Sources directly on the Help menu instead of in
  an Extra Help cascade menu.  Rearrange the Help menu so the Additional
  Help Sources come last.  Update help.txt appropriately.

- Fix Tk root pop-ups in configSectionNameDialog.py  and configDialog.py

- Uniform capitalization in General tab of ConfigDialog, update the doc string.

- Fix bug in ConfigDialog where SaveAllChangedConfig() was unexpectedly
  deleting Additional Help Sources from the user's config file.

- Make configHelpSourceEdit OK button the default and bind <Return>

- Fix Tk root pop-ups in configHelpSourceEdit: error dialogs not attached
  to parents.

- Use os.startfile() to open both Additional Help and Python Help on the
  Windows platform.  The application associated with the file type will act as
  the viewer.  Windows help files (.chm) are now supported via the
  Settings/General/Additional Help facility.

- If Python Help files are installed locally on Linux, use them instead of
  accessing python.org.

- Make the methods for finding the Python help docs more robust, and make
  them work in the installed configuration, also.

- On the Save Before Run dialog, make the OK button the default.  One
  less mouse action!

- Add a method: EditorWindow.get_geometry() for future use in implementing
  window location persistence.

- Removed the "Help/Advice" menu entry.  Thanks, David!  We'll remember!

- Change the "Classic Windows" theme's paste key to be <ctrl-v>.

- Rearrange the Shell menu to put Stack Viewer entries adjacent.

- Add the ability to restart the subprocess interpreter from the shell window;
  add an associated menu entry "Shell/Restart" with binding Control-F6.  Update
  IDLE help.

- Upon a restart, annotate the shell window with a "restart boundary".  Add a
  shell window menu "Shell/View Restart" with binding F6 to jump to the most
  recent restart boundary.

- Add Shell menu to Python Shell; change "Settings" to "Options".

- Remove incorrect comment in setup.py: IDLEfork is now installed as a package.

- Add INSTALL.txt, HISTORY.txt, NEWS.txt to installed configuration.

- In installer text, fix reference to Visual Python, should be VPython.
  Properly credit David Scherer.

- Modified idle, idle.py, idle.pyw to improve exception handling.


What's New in IDLEfork 0.9 Alpha 1?
===================================
*Release date: 31-Dec-2002*

- First release of major new functionality.  For further details refer to
  Idle-dev and/or the Sourceforge CVS.

- Adapted to the Mac platform.

- Overhauled the IDLE startup options and revised the idle -h help message,
  which provides details of command line usage.

- Multiple bug fixes and usability enhancements.

- Introduced the new RPC implementation, which includes a debugger.  The output
  of user code is to the shell, and the shell may be used to inspect the
  environment after the run has finished.  (In version 0.8.1 the shell
  environment was separate from the environment of the user code.)

- Introduced the configuration GUI and a new About dialog.

- Removed David Scherer's Remote Procedure Call code and replaced with Guido
  van Rossum's.  GvR code has support for the IDLE debugger and uses the shell
  to inspect the environment of code Run from an Edit window.  Files removed:
  ExecBinding.py, loader.py, protocol.py, Remote.py, spawn.py

IDLE MENUS
Top level items and most submenu items are defined in Bindings.
Extenstions add submenu items when active.  The names given are
found, quoted, in one of these modules, paired with a '<<pseudoevent>>'.
Each pseudoevent is bound to an event handler.  Some event handlers
call another function that does the actual work.  The annotations below
are intended to at least give the module where the actual work is done.

Original IDLE todo, much of it now outdated:
============================================
TO DO:

- improve debugger:
    - manage breakpoints globally, allow bp deletion, tbreak, cbreak etc.
    - real object browser
    - help on how to use it (a simple help button will do wonders)
    - performance?  (updates of large sets of locals are slow)
    - better integration of "debug module"
    - debugger should be global resource (attached to flist, not to shell)
    - fix the stupid bug where you need to step twice
    - display class name in stack viewer entries for methods
    - suppress tracing through IDLE internals (e.g. print) DONE
    - add a button to suppress through a specific module or class or method
    - more object inspection to stack viewer, e.g. to view all array items
- insert the initial current directory into sys.path DONE
- default directory attribute for each window instead of only for windows
  that have an associated filename
- command expansion from keywords, module contents, other buffers, etc.
- "Recent documents" menu item DONE
- Filter region command
- Optional horizontal scroll bar
- more Emacsisms:
    - ^K should cut to buffer
    - M-[, M-] to move by paragraphs
    - incremental search?
- search should indicate wrap-around in some way
- restructure state sensitive code to avoid testing flags all the time
- persistent user state (e.g. window and cursor positions, bindings)
- make backups when saving
- check file mtimes at various points
- Pluggable interface with RCS/CVS/Perforce/Clearcase
- better help?
- don't open second class browser on same module (nor second path browser)
- unify class and path browsers
- Need to define a standard way whereby one can determine one is running
  inside IDLE (needed for Tk mainloop, also handy for $PYTHONSTARTUP)
- Add more utility methods for use by extensions (a la get_selection)
- Way to run command in totally separate interpreter (fork+os.system?) DONE
- Way to find definition of fully-qualified name:
  In other words, select "UserDict.UserDict", hit some magic key and
  it loads up UserDict.py and finds the first def or class for UserDict.
- need a way to force colorization on/off
- need a way to force auto-indent on/off

Details:

- ^O (on Unix -- open-line) should honor autoindent
- after paste, show end of pasted text
- on Windows, should turn short filename to long filename (not only in argv!)
  (shouldn't this be done -- or undone -- by ntpath.normpath?)
- new autoindent after colon even indents when the colon is in a comment!
- sometimes forward slashes in pathname remain
- sometimes star in window name remains in Windows menu
- With unix bindings, ESC by itself is ignored
- Sometimes for no apparent reason a selection from the cursor to the
  end of the command buffer appears, which is hard to get rid of
  because it stays when you are typing!
- The Line/Col in the status bar can be wrong initially in PyShell DONE

Structural problems:

- too much knowledge in FileList about EditorWindow (for example)
- should add some primitives for accessing the selection etc.
  to repeat cumbersome code over and over

======================================================================

Jeff Bauer suggests:

- Open Module doesn't appear to handle hierarchical packages.
- Class browser should also allow hierarchical packages.
- Open and Open Module could benefit from a history, DONE
  either command line style, or Microsoft recent-file
  style.
- Add a Smalltalk-style inspector  (i.e. Tkinspect)

The last suggestion is already a reality, but not yet
integrated into IDLE.  I use a module called inspector.py,
that used to be available from python.org(?)  It no longer
appears to be in the contributed section, and the source
has no author attribution.

In any case, the code is useful for visually navigating
an object's attributes, including its container hierarchy.

    >>> from inspector import Tkinspect
    >>> Tkinspect(None, myObject)

Tkinspect could probably be extended and refined to
integrate better into IDLE.

======================================================================

Comparison to PTUI
------------------

+ PTUI's help is better (HTML!)

+ PTUI can attach a shell to any module

+ PTUI has some more I/O commands:
  open multiple
  append
  examine (what's that?)

======================================================================

Notes after trying to run Grail
-------------------------------

- Grail does stuff to sys.path based on sys.argv[0]; you must set
sys.argv[0] to something decent first (it is normally set to the path of
the idle script).

- Grail must be exec'ed in __main__ because that's imported by some
other parts of Grail.

- Grail uses a module called History and so does idle :-(

======================================================================

Robin Friedrich's items:

Things I'd like to see:
    - I'd like support for shift-click extending the selection. There's a
      bug now that it doesn't work the first time you try it.
    - Printing is needed. How hard can that be on Windows? FIRST CUT DONE
    - The python-mode trick of autoindenting a line with <tab> is neat and
      very handy.
    - (someday) a spellchecker for docstrings and comments.
    - a pagedown/up command key which moves to next class/def statement (top
      level)
    - split window capability
    - DnD text relocation/copying

Things I don't want to see.
    - line numbers...  will probably slow things down way too much.
    - Please use another icon for the tree browser leaf. The small snake
      isn't cutting it.

----------------------------------------------------------------------

- Customizable views (multi-window or multi-pane).  (Markus Gritsch)

- Being able to double click (maybe double right click) on a callable
object in the editor which shows the source of the object, if
possible.  (Gerrit Holl)

- Hooks into the guts, like in Emacs.  (Mike Romberg)

- Sharing the editor with a remote tutor.  (Martijn Faassen)

- Multiple views on the same file.  (Tony J Ibbs)

- Store breakpoints in a global (per-project) database (GvR); Dirk
Heise adds: save some space-trimmed context and search around when
reopening a file that might have been edited by someone else.

- Capture menu events in extensions without changing the IDLE source.
(Matthias Barmeier)

- Use overlapping panels (a "notebook" in MFC terms I think) for info
that doesn't need to be accessible simultaneously (e.g. HTML source
and output).  Use multi-pane windows for info that does need to be
shown together (e.g. class browser and source).  (Albert Brandl)

- A project should invisibly track all symbols, for instant search,
replace and cross-ref.  Projects should be allowed to span multiple
directories, hosts, etc.  Project management files are placed in a
directory you specify.  A global mapping between project names and
project directories should exist [not so sure --GvR].  (Tim Peters)

- Merge attr-tips and auto-expand.  (Mark Hammond, Tim Peters)

- Python Shell should behave more like a "shell window" as users know
it -- i.e. you can only edit the current command, and the cursor can't
escape from the command area.  (Albert Brandl)

- Set X11 class to "idle/Idle", set icon and title to something
beginning with "idle" -- for window manangers.  (Randall Hopper)

- Config files editable through a preferences dialog.  (me) DONE

- Config files still editable outside the preferences dialog.
(Randall Hopper) DONE

- When you're editing a command in PyShell, and there are only blank
lines below the cursor, hitting Return should ignore or delete those
blank lines rather than deciding you're not on the last line.  (me)

- Run command (F5 c.s.) should be more like Pythonwin's Run -- a
dialog with options to give command line arguments, run the debugger,
etc.  (me)

- Shouldn't be able to delete part of the prompt (or any text before
it) in the PyShell.  (Martijn Faassen)   DONE

- Emacs style auto-fill (also smart about comments and strings).
(Jeremy Hylton)

- Output of Run Script should go to a separate output window, not to
the shell window.  Output of separate runs should all go to the same
window but clearly delimited.  (David Scherer) REJECT FIRST, LATTER DONE

- GUI form designer to kick VB's butt.  (Robert Geiger) THAT'S NOT IDLE

- Printing!  Possibly via generation of PDF files which the user must
then send to the printer separately.  (Dinu Gherman)  FIRST CUT
# Grammar for 2to3. This grammar supports Python 2.x and 3.x.

# Note:  Changing the grammar specified in this file will most likely
#        require corresponding changes in the parser module
#        (../Modules/parsermodule.c).  If you can't make the changes to
#        that module yourself, please co-ordinate the required changes
#        with someone who can; ask around on python-dev for help.  Fred
#        Drake <fdrake@acm.org> will probably be listening there.

如何在 Python 中使用既有的 C library?
　在資訊科技快速發展的今天, 開發及測試軟體的速度是不容忽視的
課題. 為加快開發及測試的速度, 我們便常希望能利用一些已開發好的
library, 並有一個 fast prototyping 的 programming language 可
供使用. 目前有許許多多的 library 是以 C 寫成, 而 Python 是一個
fast prototyping 的 programming language. 故我們希望能將既有的
C library 拿到 Python 的環境中測試及整合. 其中最主要也是我們所
要討論的問題就是:

Python の開発は、1990 年ごろから開始されています。
開発者の Guido van Rossum は教育用のプログラミング言語「ABC」の開発に参加していましたが、ABC は実用上の目的にはあまり適していませんでした。
このため、Guido はより実用的なプログラミング言語の開発を開始し、英国 BBS 放送のコメディ番組「モンティ パイソン」のファンである Guido はこの言語を「Python」と名づけました。
このような背景から生まれた Python の言語設計は、「シンプル」で「習得が容易」という目標に重点が置かれています。
多くのスクリプト系言語ではユーザの目先の利便性を優先して色々な機能を言語要素として取り入れる場合が多いのですが、Python ではそういった小細工が追加されることはあまりありません。
言語自体の機能は最小限に押さえ、必要な機能は拡張モジュールとして追加する、というのが Python のポリシーです。

-- Testcases for functions in cmath.
--
-- Each line takes the form:
--
-- <testid> <function> <input_value> -> <output_value> <flags>
--
-- where:
--
--   <testid> is a short name identifying the test,
--
--   <function> is the function to be tested (exp, cos, asinh, ...),
--
--   <input_value> is a pair of floats separated by whitespace
--     representing real and imaginary parts of a complex number, and
--
--   <output_value> is the expected (ideal) output value, again
--     represented as a pair of floats.
--
--   <flags> is a list of the floating-point flags required by C99
--
-- The possible flags are:
--
--   divide-by-zero : raised when a finite input gives a
--     mathematically infinite result.
--
--   overflow : raised when a finite input gives a finite result whose
--     real or imaginary part is too large to fit in the usual range
--     of an IEEE 754 double.
--
--   invalid : raised for invalid inputs.
--
--   ignore-real-sign : indicates that the sign of the real part of
--     the result is unspecified; if the real part of the result is
--     given as inf, then both -inf and inf should be accepted as
--     correct.
--
--   ignore-imag-sign : indicates that the sign of the imaginary part
--     of the result is unspecified.
--
-- Flags may appear in any order.
--
-- Lines beginning with '--' (like this one) start a comment, and are
-- ignored.  Blank lines, or lines containing only whitespace, are also
-- ignored.

-- The majority of the values below were computed with the help of
-- version 2.3 of the MPFR library for multiple-precision
-- floating-point computations with correct rounding.  All output
-- values in this file are (modulo yet-to-be-discovered bugs)
-- correctly rounded, provided that each input and output decimal
-- floating-point value below is interpreted as a representation of
-- the corresponding nearest IEEE 754 double-precision value.  See the
-- MPFR homepage at http://www.mpfr.org for more information about the
-- MPFR project.

-- rect: Conversion from polar coordinates to rectangular coordinates --
------------------------------------------------------------------------
--
-- For cmath.rect, we can use the same testcase syntax as for the
-- complex -> complex functions above, but here the input arguments
-- should be interpreted as a pair of floating-point numbers rather
-- than the real and imaginary parts of a complex number.
--
-- Here are the 'spirit of C99' rules for rect.  First, the short
-- version:
--
--    rect(x, t) = exp(log(x)+it) for positive-signed x
--    rect(x, t) = -exp(log(-x)+it) for negative-signed x
--    rect(nan, t) = exp(nan + it), except that in rect(nan, +-0) the
--      sign of the imaginary part is unspecified.
--
-- and now the long version:
--
--   rect(x, -t) = conj(rect(x, t)) for all x and t
--   rect(-x, t) = -rect(x, t) for all x and t
--   rect(+0, +0) returns +0 + i0
--   rect(+0, inf) returns +- 0 +- i0, where the signs of the real and
--     imaginary parts are unspecified.
--   rect(x, inf) returns NaN + i NaN and raises the "invalid"
--     floating-point exception, for finite nonzero x.
--   rect(inf, inf) returns +-inf + i NaN and raises the "invalid"
--     floating-point exception (where the sign of the real part of the
--     result is unspecified).
--   rect(inf, +0) returns inf+i0
--   rect(inf, x) returns inf*cis(x), for finite nonzero x
--   rect(inf, NaN) returns +-inf+i NaN, where the sign of the real part
--     of the result is unspecified.
--   rect(NaN, x) returns NaN + i NaN for all nonzero numbers (including
--     infinities) x
--   rect(NaN, 0) returns NaN +- i0, where the sign of the imaginary
--     part is unspecified
--   rect(NaN, NaN) returns NaN + i NaN
--   rect(x, NaN) returns NaN + i NaN for finite nonzero x
--   rect(+0, NaN) return +-0 +- i0, where the signs of the real and
--     imaginary parts are unspecified.

======================================
Python IEEE 754 floating point support
======================================

>>> from sys import float_info as FI
>>> from math import *
>>> PI = pi
>>> E = e

You must never compare two floats with == because you are not going to get
what you expect. We treat two floats as equal if the difference between them
is small than epsilon.
>>> EPS = 1E-15
>>> def equal(x, y):
...     """Almost equal helper for floats"""
...     return abs(x - y) < EPS


NaNs and INFs
=============

In Python 2.6 and newer NaNs (not a number) and infinity can be constructed
from the strings 'inf' and 'nan'.

>>> INF = float('inf')
>>> NINF = float('-inf')
>>> NAN = float('nan')

>>> INF
inf
>>> NINF
-inf
>>> NAN
nan

The math module's ``isnan`` and ``isinf`` functions can be used to detect INF
and NAN:
>>> isinf(INF), isinf(NINF), isnan(NAN)
(True, True, True)
>>> INF == -NINF
True

Infinity
--------

Ambiguous operations like ``0 * inf`` or ``inf - inf`` result in NaN.
>>> INF * 0
nan
>>> INF - INF
nan
>>> INF / INF
nan

However unambigous operations with inf return inf:
>>> INF * INF
inf
>>> 1.5 * INF
inf
>>> 0.5 * INF
inf
>>> INF / 1000
inf

Not a Number
------------

NaNs are never equal to another number, even itself
>>> NAN == NAN
False
>>> NAN < 0
False
>>> NAN >= 0
False

All operations involving a NaN return a NaN except for nan**0 and 1**nan.
>>> 1 + NAN
nan
>>> 1 * NAN
nan
>>> 0 * NAN
nan
>>> 1 ** NAN
1.0
>>> NAN ** 0
1.0
>>> 0 ** NAN
nan
>>> (1.0 + FI.epsilon) * NAN
nan

Misc Functions
==============

The power of 1 raised to x is always 1.0, even for special values like 0,
infinity and NaN.

>>> pow(1, 0)
1.0
>>> pow(1, INF)
1.0
>>> pow(1, -INF)
1.0
>>> pow(1, NAN)
1.0

The power of 0 raised to x is defined as 0, if x is positive. Negative
values are a domain error or zero division error and NaN result in a
silent NaN.

>>> pow(0, 0)
1.0
>>> pow(0, INF)
0.0

Neither pi nor tan are exact, but you can assume that tan(pi/2) is a large value
and tan(pi) is a very small value:
>>> tan(PI/2) > 1E10
True
>>> -tan(-PI/2) > 1E10
True
>>> tan(PI) < 1E-15
True

>>> asin(NAN), acos(NAN), atan(NAN)
(nan, nan, nan)
>>> asin(INF), asin(NINF)
Traceback (most recent call last):

Traceback (most recent call last):

>>> equal(atan(INF), PI/2), equal(atan(NINF), -PI/2)
(True, True)


Hyberbolic Functions
====================

This directory contains test cases that are known to leak references.
The idea is that you can import these modules while in the interpreter
and call the leak function repeatedly.  This will only be helpful if
the interpreter was built in debug mode.  If the total ref count
doesn't increase, the bug has been fixed and the file should be removed
from the repository.

Note:  be careful to check for cyclic garbage.  Sometimes it may be helpful
to define the leak function like:

def leak():
    def inner_leak():
        # this is the function that leaks, but also creates cycles
    inner_leak()
    gc.collect() ; gc.collect() ; gc.collect()

Here's an example interpreter session for test_gestalt which still leaks:

>>> from test.leakers.test_gestalt import leak
[24275 refs]
>>> leak()
[28936 refs]
>>> leak()
[28938 refs]
>>> leak()
[28940 refs]
>>> 

Once the leak is fixed, the test case should be moved into an appropriate
test (even if it was originally from the test suite).  This ensures the
regression doesn't happen again.  And if it does, it should be easier
to track down.

-- Testcases for functions in math.
--
-- Each line takes the form:
--
-- <testid> <function> <input_value> -> <output_value> <flags>
--
-- where:
--
--   <testid> is a short name identifying the test,
--
--   <function> is the function to be tested (exp, cos, asinh, ...),
--
--   <input_value> is a string representing a floating-point value
--
--   <output_value> is the expected (ideal) output value, again
--     represented as a string.
--
--   <flags> is a list of the floating-point flags required by C99
--
-- The possible flags are:
--
--   divide-by-zero : raised when a finite input gives a
--     mathematically infinite result.
--
--   overflow : raised when a finite input gives a finite result that
--     is too large to fit in the usual range of an IEEE 754 double.
--
--   invalid : raised for invalid inputs (e.g., sqrt(-1))
--
--   ignore-sign : indicates that the sign of the result is
--     unspecified; e.g., if the result is given as inf,
--     then both -inf and inf should be accepted as correct.
--
-- Flags may appear in any order.
--
-- Lines beginning with '--' (like this one) start a comment, and are
-- ignored.  Blank lines, or lines containing only whitespace, are also
-- ignored.

-- Many of the values below were computed with the help of
-- version 2.4 of the MPFR library for multiple-precision
-- floating-point computations with correct rounding.  All output
-- values in this file are (modulo yet-to-be-discovered bugs)
-- correctly rounded, provided that each input and output decimal
-- floating-point value below is interpreted as a representation of
-- the corresponding nearest IEEE 754 double-precision value.  See the
-- MPFR homepage at http://www.mpfr.org for more information about the

This is a sample doctest in a text file.

In this example, we'll rely on a global variable being set for us
already:

  >>> favorite_color
  'blue'

We can make this fail by disabling the blank-line feature.

  >>> if 1:
  ...    print('a')
  ...    print()
  ...    print('b')
  a
  <BLANKLINE>
  b
This is a sample doctest in a text file.

In this example, we'll rely on some silly setup:

  >>> import test.test_doctest
  >>> test.test_doctest.sillySetup
  True

This test also has some (random) encoded (utf-8) unicode text:

  ЉЊЈЁЂ

This doesn't cause a problem in the tect surrounding the examples, but
we include it here (in this test text file) to make sure. :)

Here we check that `__file__` is provided:

  >>> type(__file__)
  <class 'str'>
This is a sample doctest in a text file that contains non-ASCII characters.
This file is encoded using UTF-8.

In order to get this test to pass, we have to manually specify the
encoding.

  >>> 'föö'
  'f\xf6\xf6'

  >>> 'bąr'
  'b\u0105r'

Unlike the test test_nested-multiples-with-internal-boundary, this
piece of text not only contains the outer boundary tags 
------- =_aaaaaaaaaa1 
and 
------- =_aaaaaaaaaa0 
but puts them at the start of a line! And, to be even nastier, it
even includes a couple of end tags, such as this one:

------- =_aaaaaaaaaa1--

and this one, which is from a multipart we haven't even seen yet!

------- =_aaaaaaaaaa4--

This will, I'm sure, cause much breakage of MIME parsers. But, as 
far as I can tell, it's perfectly legal. I have not yet ever seen
a case of this in the wild, but I've seen *similar* things.
