"""Class browser.
XXX TO DO:
- reparse when source changed (maybe just a button would be OK?)
(or recheck on window popup)
- add popup menu with more options (e.g. doc strings, base classes, imports)
- show function argument list? (have to do pattern matching on source)
- should the classes and methods lists also be in the module's menu bar?
- add base classes to class browser tree

# Extension to format a paragraph
# Does basic, standard text formatting, and also understands Python
# comment blocks. Thus, for editing Python source code, this
# extension is really only suitable for reformatting these comment
# blocks or triple-quoted strings.
# Known problems with comment reformatting:
# * If there is a selection marked, and the first line of the
# selection is not complete, the block will probably not be detected
# as comments, and will have the normal "text formatting" rules
# applied.
# * If a comment block has leading whitespace that mixes tabs and
# spaces, they will not be considered part of the same block.
# * Fancy comments, like this bulleted list, arent handled :-)

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

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 or later, so it is currently only usable
with a Python 1.5.2 (or later) 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).
FEEDBACK
For feedback, please use the Python Bugs List
(http://www.python.org/search/search_bugs.html).

"""Extension to execute code outside the Python shell window.

- Check module (Alt-F5) does a full syntax check of the current module.
It also runs the tabnanny to catch any inconsistent tabs.
- Import module (F5) is equivalent to either import or reload of the
current module. The window must have been saved previously. The
module is added to sys.modules, and is also added to the __main__

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)
- 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
- 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
- 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?)
- 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:
- when there's a selection, left/right arrow should go to either
end of the selection
- ^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
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,
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?
- 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)
- Config files still editable outside the preferences dialog.
(Randall Hopper)
- 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)
- 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)
- GUI form designer to kick VB's butt. (Robert Geiger)
- Printing! Possibly via generation of PDF files which the user must
then send to the printer separately. (Dinu Gherman)

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.txt; see below for details.
An IDLE extension is defined by a class. Methods of the class define
actions that are invoked by those 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 guarateed 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 bind key events. Rather, it must define
one or more virtual events, e.g. <<zoom-height>>, and corresponding
methods, e.g. zoom_height_event(), and have one or more class (or instance)
variables that define mappings between virtual events and key sequences,
e.g. <Alt-F2>. When the extension is loaded, these key sequences will
be bound to the corresponding virtual events, and the virtual events
will be bound to the corresponding methods. (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.)
The following class or instance variables are used to define key
bindings for virtual events:
keydefs for all platforms
mac_keydefs for Macintosh
windows_keydefs for Windows
unix_keydefs for Unix (and other platforms)
Each of these variables, if it exists, must be a dictionary whose
keys are virtual events, and whose values are lists of key sequences.
An extension can define menu entries in a similar fashion. This is done
with a class or instance variable named menudefs; it should be a list of
pair, 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 the key bindings
are still applied. (This should probably be refined in the future.)
Here is a complete example example:
class ZoomHeight:
menudefs = [
('edit', [
None, # Separator
('_Zoom Height', '<<zoom-height>>'),
])
]
windows_keydefs = {
'<<zoom-height>>': ['<Alt-F2>'],
}
unix_keydefs = {
'<<zoom-height>>': ['<Control-z><Control-z>'],
}
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.txt", which is used
to to configure the loading of extensions. For each extension,
you must include a section in config.txt (or in any of the other
configuration files that are consulted at startup: config-unix.txt,
config-win.txt, or ~/.idle). A section is headed by the module name
in square brackets, e.g.
[ZoomHeight]
The section may be empty, or it may define configuration options for
the extension. (See ParenMatch.py for an example.) A special option
is 'enable': including
enable = 0
in a section disables that extension. More than one configuration
file may specify options for the same extension, so a user may disable
an extension that is loaded by default, or enable an extension that is
disabled by default.
Extensions can define key bindings and menu entries that reference
events they don't implement (including standard events); however this is
not recommended (and may be forbidden in the future).
Extensions are not required to define menu entries for all events they
implement.
Note: in order to change key bindings, you must currently edit the file
keydefs. It contains two dictionaries named and formatted like the
keydefs dictionaries described above, one for the Unix bindings and one
for the Windows bindings. In the future, a better mechanism will be
provided.

[See end for tips.]
Click on the dotted line at the top of a menu to "tear it off": a
separate window containing the menu is created.
File menu:
New window -- create a new editing window
Open... -- open an existing file
Open module... -- open an existing module (searches sys.path)
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
---
Close -- close current window (asks to save if unsaved)
Exit -- close all windows and quit IDLE (asks to save if unsaved)
Edit menu:
Undo -- Undo last change to current window (max 1000 changes)
Redo -- Redo last undone change to current window
---
Cut -- Copy selection into system-wide clipboard; then delete 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
---
Indent region -- Shift selected lines right 4 spaces
Dedent region -- Shift selected lines left 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
Untabify region -- Turn *all* tabs into the right number of spaces
Expand word -- Expand the word you have typed to match another
word in the same buffer; repeat to get a different expansion
Format Paragraph -- Reformat the current blank-line-separated paragraph
---
Import module -- Import or reload the current module
Run script -- Execute the current file in the __main__ namespace
Windows menu:
Zoom Height -- toggles the window between normal size (24x80)
and maximum height.
---
The rest of this menu lists the names of all open windows;
select one to bring it to the foreground (deiconifying it if
necessary).
Debug menu (in the Python Shell window only):
Go to file/line -- look around the insert point for a filename
and linenumber, open the file, and show the line
Open stack viewer -- show the stack traceback of the last exception
Debugger toggle -- Run commands in the shell under the debugger
JIT Stack viewer toggle -- Open stack viewer on traceback
Basic editing and navigation:
Backspace deletes to the left; DEL deletes to the right
Arrow keys and Page Up/Down to move around
Home/End go to begin/end of line
Control-Home/End go to begin/end of file
Some Emacs bindings may also work, e.g. ^B/^P/^A/^E/^D/^L
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 1-4 spaces (in the
Python Shell window one tab). See also the indent/dedent
region commands in the edit menu.
Python Shell window:
^C interrupts executing command
^D sends end-of-file; closes window if typed at >>> prompt
Command history:
Alt-p retrieves previous command matching what you have typed
Alt-n retrieves next
Return while on any previous command retrieves that command
Alt-/ (Expand word) is also useful here
Syntax colors:
The coloring is applied in a background "thread", so you may
occasionally see uncolorized text. To change the color
scheme, edit the [Colors] section in config.txt (or add a
[Colors] section to ~/.idle).
Python syntax colors:
Keywords orange
Strings green
Comments red
Definitions blue
Shell colors:
Console output brown
stdout blue
stderr dark green
stdin black
Other preferences:
Most preferences can be changed by editing one of the
configuration text files: config.txt (generic) or one of
config-unix.txt, config-win.txt, config.mac.txt (platform
specific). User-specific preferences can be stored in
$HOME/.idle, which overrides the config*.txt files.
To change keyboard bindings, edit Bindings.py
Command line usage:
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:
If -e is used, arguments are files opened for editing and
sys.argv reflects the arguments passed to IDLE itself.
Otherwise, if -c is used, all arguments are placed in
sys.argv[1:...], with sys.argv[0] set to '-c'.
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
