EXPERIMENTAL LOADER IDLE 2000-05-29
|
|
-----------------------------------
|
|
|
|
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
|
|
------------------------
|
|
|
|
This is an early release of IDLE, my own attempt at a Tkinter-based
|
|
IDE for Python.
|
|
|
|
For news about this release, see the file NEWS.txt. (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).
