IDLEfork Credits
==================
Guido van Rossum, as well as being the creator of the Python language, is
the original creator of IDLE. He also developed the RPC code and Remote
Debugger extension used in IDLEfork.
The IDLEfork project was initiated and brought up to version 0.7.1 primarily
by David Scherer, with help from Peter Schneider-Kamp and Nicholas Riley.
Bruce Sherwood has contributed considerable time testing and suggesting
improvements.
Besides Guido, the main developers who have been active on IDLEfork version
0.8.1 and later are Stephen M. Gava, who implemented the Configuration GUI, the
new configuration system, and the new About menu, and Kurt B. Kaiser, who
completed the integration of the RPC and remote debugger, and made a number of
usability enhancements.
Other contributors include Raymond Hettinger, Tony Lownds (Mac integration),
Neal Norwitz (code check and clean-up), and Chui Tey (RPC integration, debugger
integration and persistent breakpoints).
Hernan Foffani, Christos Georgiou, Jason Orendorff, Josh Robb, and Bruce
Sherwood have submitted useful patches. Thanks, guys!
There are others who should be included here, especially those who contributed
to IDLE versions prior to 0.8, principally Mark Hammond, Jeremy Hylton,
Tim Peters, and Moshe Zadka. For additional details refer to NEWS.txt and
Changelog.
Please contact the IDLEfork maintainer to have yourself included here if you
are one of those we missed!

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.
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.

IDLEfork Installation Notes
===========================
IDLEfork requires Python Version 2.2 or later.
There are several distribution files (where xx is the subversion):
IDLEfork-0.9xx.win32.exe
This is a Windows installer which will install IDLEfork in
..../site-packages/idleforklib/ and place the idefork startup script
at ..../scripts/idlefork. Rename this to idlefork.pyw and
point your launcher icons at it. Installation is as idlefork
to avoid conflict with the original Python IDLE.
IDLEfork-0.9xx-1.noarch.rpm
This is an rpm which is designed to install as idleforklib in an
existing /usr/lib/python2.2 tree. It installs as idlefork to avoid
conflict with Python IDLE.
Python rpms are available at http://www.python.org/2.2.2/rpms.html and
http://www.python.org/2.2.1/rpms.html.
IDLEfork-0.9xx.tar.gz
This is a distutils sdist (source) tarfile which can be used to make
installations on platforms not supported by the above files.
** It remains configured to install as idlelib, not idleforklib. **
Unpack in ..../Tools/, cd to the IDLEfork directory created, and
"python setup.py install" to install in ....site-packages/idlelib.
This will overwrite the Python IDLE installation.
If you don't want to overwrite Python IDLE, it is also possible to
simply call "python idle.py" to run from the IDLEfork source directory
without making an installation. In this case, IDLE will not be on
your PATH unless you are in the source directory. Also, it is then
advisable to remove any Python IDLE installation by removing
..../site-packages/idlelib so the two identically named packages don't
conflict.
On Redhat Linux systems prior to 8.0, /usr/bin/python may be pointing
at python1.5. If so, change the first line in the /usr/bin/idle
script to read:
!# /usr/bin/python2.2
See README.txt for more details on this version of IDLEfork.

# IDLE reads several config files to determine user preferences. This
# file is the default config file for general idle settings.
#
# When IDLE starts, it will look in
# the following two sets of files, in order:
#
# default configuration
# ---------------------
# config-main.def the default general config file
# config-extensions.def the default extension config file
# config-highlight.def the default highlighting config file
# config-keys.def the default keybinding config file
#
# user configuration
# -------------------
# ~/.idlerc/idle-main.cfg the user general config file
# ~/.idlerc/idle-extensions.cfg the user extension config file
# ~/.idlerc/idle-highlight.cfg the user highlighting config file
# ~/.idlerc/idle-keys.cfg the user keybinding config file
#
# Any options the user saves through the config dialog will be saved to
# the relevant user config file. Reverting any general setting to the
# default causes that entry to be wiped from the user file and re-read
# from the default file. User highlighting themes or keybinding sets are
# retained unless specifically deleted within the config dialog. Choosing
# one of the default themes or keysets just applies the relevant settings
# from the default file.
#
# Additional help sources are listed in the [HelpFiles] section and must be
# viewable by a web browser (or the Windows Help viewer in the case of .chm
# files). These sources will be listed on the Help menu. The pattern is
# <sequence_number = menu item;/path/to/help/source>
# You can't use a semi-colon in a menu item or path. The path will be platform
# specific because of path separators, drive specs etc.
#
# It is best to use the Configuration GUI to set up additional help sources!
# Example:
#1 = My Extra Help Source;/usr/share/doc/foo/index.html
#2 = Another Help Source;/path/to/another.pdf

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

In the Python subprocess, RPCServer is instantiated with handlerclass
MyHandler, which inherits register/unregister methods from RPCHandler via
the mix-in class SocketIO.
When the RPCServer 'server' is instantiated, the TCPServer initialization
creates an instance of run.MyHandler and calls its handle() method.
handle() instantiates a run.Executive object, passing it a reference to the
MyHandler object. That reference is saved as attribute rpchandler of the
Executive instance. The Executive methods have access to the reference and
can pass it on to entities that they command
(e.g. RemoteDebugger.Debugger.start_debugger()). The latter, in turn, can
call MyHandler(SocketIO) register/unregister methods via the reference to
register and unregister themselves.
