ANN: Leo 4.10 b1 released
Leo 4.10 b1 is now available at: http://sourceforge.net/projects/leo/files/ Leo is a text editor, data organizer, project manager and much more. http://webpages.charter.net/edreamleo/intro.html Leo 4.10 contains 9 months of intense work on Leo. Several very important features are subtle; you could almost call them Easter Eggs, so please read the following notes carefully. The highlights of Leo 4.10: -- * Dozens of new and improved features and commands, including... - Tab completion now shows all @command & @button nodes. - Leo tabs may be detached from the main window. - The Open With menu now works. - The leoInspect module answers questions about Python code. - Leo can highlight the pane containing the focus. - The bigdash plugin searches across multiple files. - Improved abbreviation capabilities. - Improved handling of URL's. - Improved editing of non-Leo files. - Improvements create "weightless" unit testing. * Easier installation on MacOS. * Fixed almost 70 bugs. The Easter Eggs --- 1. Tab completion now shows all @command & @button nodes. Put all your common scripts in @command nodes in myLeoSettings.leo. Typing @c will remind you of the names of these scripts. You can execute the scripts by name without the "@command-" prefix. 2. Improved abbreviation capabilities. Virtually any kind of abbreviation is possible. For example, ~a to ã. 3. Improved handling of URL's. URL's can link to other Leo outlines. Ctrl-Click on nodes or URL's in body text to activate the URL. 4 Weightless unit testing. The mantra is edit, alt-4 (run-marked-unit-tests-externally), edit, alt-4,... Several seemingly innocuous changes made this work without an "friction". The result is a remarkable increase in productivity.

ANN: Leo 4.4a1 released
Leo 4.4 alpha 1 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 To learn about Leo, see: http://webpages.charter.net/edreamleo/intro.html Leo 4.4 adds an Emacs-like minibuffer and support for all frequently-used Emacs commands. Emacs users will be able to choose key bindings compatible with their present finger habits. Eventually, Vim users will be able to do the same. This is definitely an alpha release; several minibuffer commands are buggy. However, this release also significantly improves Leo's error recovery capabilities. This may be the most robust version of Leo ever released. The highlights of Leo 4.4 alpha 1: -- - Support for all frequently-used Emacs commands, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. - An Emacs-like minibuffer: you can now execute any command by name from the minibuffer, both the new Emacs-style commands and traditional Leo commands. - You can define key bindings for all commands, including the new minibuffer commands, using @shortcuts nodes in leoSettings.leo files. You can define multiple sets of key bindings and switch between those sets easily. - Several fixes to the 4.3 code base. Coming in later releases of Leo 4.4: - Support for 'mouseless Leo'. There will be commands to manipulate all aspects of Leo using commands, so your fingers will never have to leave the keyboard. - Support for Vim and other 'plain-key' command modes.

ANN: Leo 4.4a2 released
Leo 4.4 alpha 2 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 To learn about Leo, see: http://webpages.charter.net/edreamleo/intro.html Leo 4.4a2 contains some of the most important changes to Leo's look (tabbed log) and feel (per-pane key bindings) in Leo's history. This release is a big step forward in meeting the following goals: - To allow Emacs and Vim users to retain their present 'finger habits'. - To support an emacs-like minibuffer, complete with typing completion. - To make Leo usable without a mouse (mouseless Leo). This is an alpha release: there are known bugs (see below). However, you should be able to use this version safely. In particular, the Leo 4.4 code base recovers from errors more reliably than all previous versions. The highlights of Leo 4.4: -- - An Emacs-like mini-buffer: you can now execute any command by typing its long name. Support for tab completion. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The 'Completion' tab shows possible typing completions. - Support for almost all commands in the Emacs Cmds menu, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. - Per-pane key bindings. You can bind shortcuts to multiple commands depending on which of Leo's panes presently has focus. For example, you can use arrow keys to move nodes in the outline pane, while retaining their defaults in Leo's body pane. Per-pane key binds are essential for mouseless Leo. - @command nodes create minibuffer commands. You can bind key shortcuts to @button and @command nodes. - A rewrite of Leo's keystroke handling. In particular, Leo handles key events immediately rather than queuing them for idle time. - Several fixes made to the 4.3 code base. In particular, Leo 4.4 continues after crashes much more reliably than in any previous version. Known bugs in Leo 4.4a2 --- - (Reported after a2 released): Canceling the Open dialog crashes. Leo recovers without incident. - Typing in the minibuffer doesn't work if the focus is 'in limbo', that is, not in the outline, body or log panes. Leo usually forces the focus to the body pane in such cases, but the code doesn't always work and sometimes causes other problems. This *minor* annoyance will be fixed completely in Leo 4.4a3. - Several minibuffer commands do not work; many new features lack unit tests. Coming in later releases of Leo 4.4: - More support for mouseless Leo. There will be commands to manipulate all aspects of Leo using commands, so your fingers will never have to leave the keyboard. - Support for Vim and other 'plain-key' input modes.

ANN: Leo 4.3-a1 released
Leo 4.3 alpha 1 is now available at http://sourceforge.net/projects/leo/ Leo 4.3 is the culmination of more than four months of work. In spite of its alpha status, I recommend Leo 4.3a1 over any 4.2 release. The defining features of Leo 4.3: - 1. Leo now stores options in @settings trees, that is, outlines whose headline is '@settings'. When opening a .leo file, Leo looks for @settings trees not only in the outline being opened but also in various leoSettings.leo files. The key design goal of @settings trees was that Leo's user options must be infinitely flexible. That goal has been accomplished. Indeed, users can create arbitrarily complex user options with @settings trees. Leo settings outlines are, in fact, infinitely more flexible and powerful than any scheme based on flat text. Readers of Python's configParser shootout take note. 2. The Preferences command temporarily replaces the outline pane with an outline showing all the @settings trees in effect. The Preferences command also replaces the body pane with a "settings pane". This settings pane allows you to change the settings selected in the outline pane using standard gui widgets. The settings pane is dynamically created from nodes in the settings tree; it is as extensible as the @settings tree itself. 3. Leo's read/write code in leoAtFile.py has been rewritten to support user-defined tangling and untangling. This is a major cleanup of Leo's core. 4. Leo now boasts a wonderful new Plugins Manager plugin. This plugin enables and disables plugins automatically. You never have to mess with pluginsManager.txt again. This plugin also tells you everything you need to know about each plugin. Finally, this plugin also lets you download plugins from Leo's cvs site. 5. You can install third-party extensions in Leo's extensions directory. Leo will attempt to import such extensions from the extensions directory if normal imports fail. As usual, version 4.3 contains many other improvements and bug fixes. What people are saying about Leo "I am using Leo since a few weeks and I brim over with enthusiasm for it. I think it is the most amazing software since the invention of the spreadsheet." -- juergen_r "We who use Leo know that it is a breakthrough tool and a whole new way of writing code." -- Joe Orr "I am a huge fan of Leo. I think it's quite possibly the most revolutionary programming tool I have ever used and it (along with the Python language) has utterly changed my view of programming (indeed of writing) forever." -- Shakeeb Alireza "Thank you very much for Leo. I think my way of working with data will change forever...I am certain [Leo] will be a revolution. The revolution is as important as the change from sequential linear organization of a book into a web-like hyperlinked pages. The main concept that impress me is that the source listing isn't the main focus any more. You focus on the non-linear, hierarchical, collapsible outline of the source code." -- Korakot Chaovavanich "Leo is a quantum leap for me in terms of how many projects I can manage and how much information I can find and organize and store in a useful way." -- Dan Winkler "Wow, wow, and wow...I finally understand how to use clones and I realized that this is exactly how I want to organize my information. Multiple views on my data, fully interlinkable just like my thoughts." -- Anon. "A few years back I would have said Zope was #1 Python showcase, but I agree 100% that Leo is tops now." -- Jason Cunliffe "Leo is the most interesting Python project I know of...I see lots of stuff posted on the Daily Python page, but I usually yawn and come over to this forum to see what's cooking." -- Anon More quotes at: http://webpages.charter.net/edreamleo/testimonials.html What makes Leo special? --- - Leo's outlines add a new dimension to programming. - Leo shows you your code and data the way _you_ want to see them. - Leo extends, completes and simplifies literate programming. - Leo's script buttons bring scripts to data. What is Leo? - A programmer's editor, an outlining editor and a flexible browser. - A literate programming tool, compatible with noweb and CWEB. - A data organizer and project manager. Leo provides multiple views of projects within a single outline. - Fully scriptable using Python.

The distribution contains Python Mega Widgets in the extensions directory. What people are saying about Leo "[Leo] should either replace or greatly augment the development tools that I use." -- Zak Greant "Leo is a marriage of outlining and literate programming. Pure genius. The main reason I am impressed with this tool is that it doesn't affect your choice of tools. You can use whatever IDE for whatever language and switch back and forth between Leo and it." -- Austin King "Leo is the best IDE that I have had the pleasure to use. I have been using it now for about 2--3 months. It has totally changed not only the way that I program, but also the way that I store and organize all of the information that I need for the job that I do." -- Ian Mulvany "I only have one week of Leo experience but I already know it will be my default IDE/project manager...people complain about the lack of a project manager for the free/standard Python IDE's like Idle. Leo clearly solves that problem and in a way that commercial tools can't touch." -- Marshall Parsons "[Leo has] become my main development platform, and I do this for a living. -- Nicola Larosa "I have been using Leo for about 3 weeks and I hardly use my other programming editor anymore...I find it easy and enjoyable to use. I plan to adopt it as my presentation tool for code reviews." -- Jim Vickroy "I'm absolutely astounded by the power of such a simple idea! It works great and I can immediately see the benefits of using Leo in place of the standard flat file editor." -- Tom Lee, <[EMAIL PROTECTED]> I think you're really showing what open source can do and your current trajectory puts you on track to kick Emacs into the dustbin of computing history. -- Dan Winkler More quotes at: http://webpages.charter.net/edreamleo/testimonials.html What makes Leo special? --- - Leo's outlines add a new dimension to programming. - Leo shows you your code and data the way _you_ want to see them. - Leo extends, completes and simplifies literate programming. - Leo's script buttons bring scripts to data.

This will be the last alpha version of Leo 4.4. Beta 1 is coming in about a week. You should be able to use this version safely; there are no known serious bugs. To learn about Leo, see: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4: -- - An Emacs-like mini-buffer: you can now execute any command by typing its long name. Support for tab completion. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Support for most commands in the Emacs Cmds menu, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. - Per-pane key bindings. You can bind shortcuts to multiple commands depending on which of Leo's panes presently has focus. For example, you can use arrow keys to move nodes in the outline pane, while retaining their defaults in Leo's body pane. - User-specified key-binding modes. This feature makes it possible to emulate all aspects of Emacs and Vim as far as key bindings are concerned. - Leo recovers from crashes much more reliably than in any previous version. - @command nodes create minibuffer commands. You can bind key shortcuts to @button and @command nodes. - Leo handles key events and updates the screen immediately rather than queuing them for idle time. - Leo updates the screen immediately rather than waiting for idle time. This improves response.

Re: sax barfs on unicode filenames: workaround
Happily, the workaround is easy. Replace theFile with: # Use cStringIo to avoid a crash in sax when inputFileName has unicode characters. s = theFile.read() theFile = cStringIO.StringIO(s) My first attempt at a workaround was to use: s = theFile.read() parser.parseString(s) but the expat parser does not support parseString...

Tkinter: populating Mac Help menu?
Hello all, Creating a 'Help' menu 'by hand' on the Mac does not work, or rather, it creates a *second* Help menu. There are hints about how to do this at: http://tkinter.unpythonic.net/wiki/Widgets/Menu but so far those hints have not been enough :-) The following statements are the result of several happy hours experimenting with dir(obj) for several objects obj related to menus. (Jeeze, I love Python, but you knew that :-) The url above suggests that the 'official' Mac menu is named x.help, where x is the Tk name (a string) of the menubar. If menubar is the Tkinter menubar widget, then I assume that x = menubar._w. So given x (a string), how does one create a widget whose name is '%s.help' % x ? This is a can of corn in Tk, but nothing comes to mind looking at the Tkinter source code. If my app does *not* create a help menu, then even long after the Mac menubar is created, and the official (empty) Help menu is visible, menubar.children does *not* contain an entry for the official Mac Help menu. Thus, there appears to be no way to populate the official Help menu after letting Tkinter create the Help menu. Naturally, I could be wrong :-) Thanks for any help you can provide.

Re: Leo 4.4.2 final released: config bug
Drat. Leo does not remember recent files unless .leoRecentFiles.txt exists in Leo's config directory. Alas, that file is (on purpose) not part of the distribution, and Leo only creates .leoRecentFiles.txt in the users home directory. So most users will have to create .leoRecentFiles.txt in Leo's config directory 'by hand': it can start life as an empty text file. My apologies for this error. It will be fixed in Leo 4.4.2.1 in a few days. Edward -------- Edward K.

A static pychecker?
I am wondering whether anyone knows of a static source-code analyzer for Python, kinda like a static pychecker. That is, instead of being a run-time tool as pychecker is, it would be a 'compile-time' tool. If I were writing such a thing it would use the ast returned from compiler.parse. Unlike the inspect module, it would peruse the code looking for possible problems. Thanks. Edward -------- Edward K.

newlines and sax.saxutils.quoteattr
Hello all, I recently ran across a situation in which sax.saxutils.quoteattr did not work as I expected. I am writing Leo outlines as opml files http://en.wikipedia.org/wiki/OPML which forces me to write python code in xml attributes rather than xml elements (as is done in .leo files). The problem is that the sax parser I am using ignores newlines in attributes. After reading the thread at: http://mail.python.org/pipermail/python-list/2006-March/332307.html I was able to work around the problem by converting newlines to ' \n'. This makes the opml file as readable as possible (since the attributes contains newlines in addition to the character reference In addition, the sax parser seems happy. My questions: - Does anyone know whether this is guaranteed to be a general solution? That is, are sax parsers *obliged* to ignore newlines in attributes? - If sax parsers are indeed obliged to ignore newlines in attributes, would it be a good idea to (optionally?) have sax.saxutils.quoteattr perform the substitution of newlines to ' \n' ? Thanks. Edward -------- Edward K. Ream email: [EMAIL PROTECTED] Leo: http://webpages.charter.net/edreamleo/front.html -- http://mail.python.org/mailman/listinfo/python-list
Re: newlines and sax.saxutils.quoteattr
Thanks, Fredrik, for the reference to the attribute normalization algorithm. > I guess it's too late to fix OPML. It's too late for OPML 1. I'll check with Dave Winer about OPML 2.

sax barfs on unicode filenames
Hi. Presumably this is a easy question, but anyone who understands the sax docs thinks completely differently than I do :-) Following the usual cookbook examples, my app parses an open file as follows:: parser = xml.sax.make_parser() parser.setFeature(xml.sax.handler.feature_external_ges,1) # Hopefully the content handler can figure out the encoding from the element. handler = saxContentHandler(c,inputFileName,silent) parser.setContentHandler(handler) parser.parse(theFile) Here 'theFile' is an open file. Usually this works just fine, but when the filename contains u'\u8116' I get the following exception: Traceback (most recent call last): File "c:\prog\tigris-cvs\leo\src\leoFileCommands.py", line 2159, in parse_leo_file parser.parse(theFile) File "c:\python25\lib\xml\sax\expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "c:\python25\lib\xml\sax\xmlreader.py", line 119, in parse self.prepareParser(source) File "c:\python25\lib\xml\sax\expatreader.py", line 111, in prepareParser self._parser.SetBase(source.getSystemId()) UnicodeEncodeError: 'ascii' codec can't encode character u'\u8116' in position 44: ordinal not in range(128) Presumably the documentation at: http://docs.python.org/lib/module-xml.sax.xmlreader.html would be sufficient for a sax-head, but I have absolutely no idea of how to create an InputSource that can handle non-ascii filenames. Any help would be appreciated. Thanks! Edward Edward K. Ream email: [EMAIL PROTECTED] Leo: http://webpages.charter.net/edreamleo/front.html -- http://mail.python.org/mailman/listinfo/python-list
How to ask sax for the file encoding

Re: How to ask sax for the file encoding
>> Can anyone tell me how the content handler can determine the encoding of >> the file? Can sax provide this info? > there is no encoding on the "inside" of an XML document; it's all Unicode. True, but sax is reading the file, so sax is producing the unicode, so it should (must) be able to determine the encoding. Furthermore, xml files start with lines like: so it would seem reasonable for sax to be able to return 'utf-8' somehow. Am I missing something? Edward -------- Edward K.

Re: How to ask sax for the file encoding
> [The value of the encoding field] _could_ be retained, but for what > purpose? I'm asking this question because my app needs it :-) Imo, there is *no* information in any xml file that can be considered irrelvant.

The exception happens in a method to which no fileName is passed as an argument. parse_leo_file: 'C:\\prog\\tigris-cvs\\leo\\test\\unittest\\chinese?folder\\chinese?test.leo' (trace of converted fileName) Unexpected exception parsing C:\prog\tigris-cvs\leo\test\unittest\chinese?folder\chinese?test.leo Traceback (most recent call last): File "c:\prog\tigris-cvs\leo\src\leoFileCommands.py", line 2162, in parse_leo_file parser.parse(theFile) File "c:\python25\lib\xml\sax\expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "c:\python25\lib\xml\sax\xmlreader.py", line 119, in parse self.prepareParser(source) File "c:\python25\lib\xml\sax\expatreader.py", line 111, in prepareParser self._parser.SetBase(source.getSystemId()) UnicodeEncodeError: 'ascii' codec can't encode character u'\u8116' in position 44: ordinal not in range(128) To repeat, theFile is an open file. I believe the actual filename is passed nowhere as an argument to sax in my code. Just to make sure, I converted the filename to ascii in my code, and got (no surprise) exactly the same crash. I suppose a workaround would be to pass a 'file-like-object to sax instead of an open file, so that theFile.getSystemId won't crash. But this looks like a bug to me.

How to invoke a tkinter menu *itself*
Hi,
I've spent a pleasant hour or so trying to bring up a top-level Tk menu at
the same spot as it would appear if I had actually clicked the menu. That
is, I want to bring up a menu from the keyboard.
The problem is computing the x and y args to menu.post. menu.winfo_x and
menu.winfo_rootx are always 0, presumably be cause the menu isn't packed.
And I haven't been able to use menu.invoke(??) to invoke the menu *itself*.
One would think this would be a basic Tk functionality.
Any ideas? Thanks.
Edward
P.S. Here is my best so far. (It must be run from Leo for the Leo magic to
work.)
import tkFont
name = 'File' # The menu to be invoked.
# A list of all of Leo's menus.
menus = ('File','Edit','Outline','Plugins','Cmds','Window','Help')
# Compute the *approximate* x offsets of each menu.
offsets = {} ; n = 0
for z in menus:
menu = c.frame.menu.getMenu(z)
fontName = menu.cget('font')
font = tkFont.Font(font=fontName)
offsets[z] = n
# A total hack: sorta works on windows.
n += font.measure(z+' '*4)+1
top = c.frame.top # Leo magic.
topx,topy = top.winfo_rootx(),top.winfo_rooty()
menu = c.frame.menu.getMenu(name) # Leo magic.
menu.post(topx+offsets.get(name,0),topy)

There are no known problems with this release. It may be better than beta quality. Or not. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4: -- - An Emacs-like mini-buffer: you can now execute any command by typing its long name, with tab completion. - Many new commands, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. You can use Leo without using a mouse. - Flexible key bindings and input modes. You can emulate the operation of Emacs, Vim, or any other editor. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Autocompletion and calltips. - Dozens of other new features and bug fixes since Leo 4.3.3.

ANN: Leo 4.3-b1
Leo 4.3 beta 1 is now available at http://sourceforge.net/projects/leo/ Leo 4.3 beta 1 completes all major features of Leo 4.3. There are no known significant bugs. The defining features of Leo 4.3: - 1. Leo now stores options in @settings trees, that is, outlines whose headline is '@settings'. When opening a .leo file, Leo looks for @settings trees not only in the outline being opened but also in various leoSettings.leo files. Users can create arbitrarily complex user options with @settings trees. 2. The Preferences command temporarily replaces the outline pane with an outline showing all the @settings trees in effect. The Preferences command also replaces the body pane with a "settings pane". This settings pane allows you to change the settings selected in the outline pane using standard gui widgets. 3. Leo now stores recent files information in .leoRecentFiles.txt files. 4. Leo's read/write code in leoAtFile.py has been rewritten to support user-defined tangling and untangling. This is a major cleanup of Leo's core. 5. Leo now contains an excellent Plugins Manager plugin. This plugin enables and disables plugins automatically and tells you everything you need to know about each plugin. This plugin also lets you download plugins from Leo's cvs site. 6. You can install third-party extensions in Leo's extensions directory. Leo will attempt to import such extensions from the extensions directory when normal imports fail. The distribution contains Python Mega Widgets in the extensions directory. What people are saying about Leo "Another day, another breakthrough using Leo--now I realize Leo is the best URL bookmark manager there is. No more bookmarks menus or favorites lists inside the browser for me. With the @url directive I can just double click on the URL to open it in my browser. Leo lets me arrange the URLs in a hierarchy (or multiple hierarchies), attach notes to them, save clippings of things I read on the sites. It's sooo much better than anything the browsers have built in and it lets me easily use different browsers on different platforms and different machines (try that with the browsers' built-in bookmark managers)." -- Dan Winkler "I am an amateur photographer. I use plain old 35mm. film for my pictures. Over the weekend, I used Leo to organize my lists of pictures.

Where are the strings in gc.get_objects?
Hello all. I'm tracking down memory leaks in my app. To do this I wrote a
script to show the numbers of each different type of object. But it doesn't
show strings! Here is the script:
import gc,types
def printDict(d):
keys = d.keys() ; keys.sort()
print '-' * 30
for key in keys:
n = d.get(key)
print '%+6d %s' % (n,key)
d = {} ; d2 = {}
for obj in gc.get_objects():
t = type(obj)
r = repr(t)
n = d.get(r,0)
d[r] = n + 1
if t == types.InstanceType:
t = obj.__class__
r = repr(t)
n = d2.get(r,0)
d2[r] = n + 1
printDict(d)
printDict(d2)
And here is example output. The first part of the listing shows the 'raw'
type of each object, the second part of the listing shows
type(obj.__class__) for instance types.

I get similar results on both Python 2.4 and Python 2.5. I'm running on XP.
Can anyone explain were the strings are? I expect at least twice the number
of strings as there are leoNodes.vnode objects.

I think this answers the question about where the strings are: they are
enclosed in tuples. My guess is that the tuples are the way that Python's
bytecode accesses the strings. For example, there is a LOAD_CONST i
bytecode whose argument i is an index into the stack frame (or is it the
code objects). Anyway, my guess is that strings seldom (never?) exist
outside the tuple by which they are referenced. So I think this answers the
mystery, mostly.

Bug? exec converts '\n' to newline in docstrings!?
It looks like both exec and execfile are converting "\n" to an actual
newline
in docstrings!
Start idle:
Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on
win32
[rest of signon deleted]
>>> s = '''\
strings = 'abc'.split("\n")
'''
>>> print s
strings = 'abc'.split("
")
I see this in my own calls to exec and execfile. Is this a bug or am I
missing something?

Pep 3105: the end of print?
The pros and cons of making 'print' a function in Python 3.x are well discussed at: http://mail.python.org/pipermail/python-dev/2005-September/056154.html Alas, it appears that the effect of this pep would be to make it impossible to use the name 'print' in a backward compatible manner. Indeed, if a program is to compile in both Python 2.x and Python 3.x, the print function (or the print statement with parentheses) can not use the 'sep', 'end' and 'file' keywords. This in turn makes it impossible to support the effect of print with trailing comma in Python 2.x programs while retaining the name 'print'. The only workaround would be to define yet another function, with a name *other* than 'print'. This function, say print2, can support whatever features the implementer wants because it does not collide with the Python 2.x print statement. In short, pep 3105 will *discourage* rather than encourage the use of the name 'print'. Rather than invalidating most Python 2.x programs, it would seem more graceful for Python 3.x to define a [your name here] function that can be used in addition to, rather than to the exclusion of, print. Edward P.S. The existence of an automated translation script does not change the situation described above in any way. At best, such a script could change print statements to [your name here] functions, but the effect would still be the elimination of the name 'print' in all programs that aim to support Python 2.x and Python 3.x.

Re: Pep 3105: the end of print?

Backwards compatibility means that one can still run old code provided the code eschews new features. Python releases have generally been backwards compatible with previous releases, with a few minor exceptions. For example, my app runs fine on Python 2.2.2 through Python 2.5, and little work was required to make this happen. In fact, my app should run find on Python 3.x, but that's because it doesn't use print :-) In other words, the consequence of pep 3105 will be that *nobody* who wants their app to be portable will be able to use print until *everybody* has converted to Python 3.x. I doubt that is what Guido had in mind, but I may be mistaken :-) Edward -------- Edward K.

Pep 3105 breaks a *lot* of code, despite the bland assertion that most production programs don't use print. Presumably, Guido wanted to improve print in such a way that *more* people would use it.

As discussed in the original post, the problem is the reverse: the Python
2.x print statement does not support the keyword args required by the pep,
so that print(foo) **in Python 2.x** can not simulate the effect of the
print statement with a trailing comma. Here is the theorum carefully stated
and proved.
Theorem: is not possible to define a function called print in Python 3.x
such that
A) print (whatever) is syntaxtically valid in Python 2.x and
B) print(whatever) outputs what 'print whatever' outputs in Python 2.x for
all values of 'whatever'.
Proof:
It is impossible for the print function to simulate the effect of the print
statement with a trailing comma. Indeed, print ('line'), and print
('line',) (note the position of the commas) are valid in Python 2.x, but
neither does what is wanted. And print('line',end='') is invalid in Python
2.x. Let's look at some examples:
1. The following works (prints 'line after\n') in Python 2.x, but will not
suppress the newline in Python 3.x:
print('line'),
print('after')
2. The following doesn't work in Python 2.x. (It prints
"('line',)\nafter").
print ('line',)
print ('after')
3. print ('line',end='') produces a syntax error in Python 2.x:
print ('line',end='')
^
SyntaxError: invalid syntax
That's the proof. Can you find a flaw in it?

(Uhm... indeed that's the > point of 2to3.) That is not what I would call a common code base. The developer would have to run the translater every time the code changed. And if the Python 3.0 code were considered the 'master' code, the developer would need a 3to2 translater. Either disprove the theorum or give up the notion of having a common code base that uses print. Edward -------- Edward K.

What you need is *some function* > that is capable of duplicating the functionality of print, Precisely wrong. The title of this thread is 'the end of print', and the whole point of my comments is that spelling matters. I would have absolutely no objection to the pep if it specified some other name for an 'official' print function. Pick any name, preferably longer than two characters, that does not conflict with either an existing global function or module. Edward -------- Edward K.

Re: Pep 3105: the end of print?
> Even in the Python world, nobody expects to run the same code base under C Python and Jython and IronPython and PyPy. Leo now runs under CPython with both wxWidgets and Tkinter. The gui code is confined to plugins, and a similar gui plugin will suffice to run Leo under IronPython. Indeed, Leo's startup code already runs unchanged under CPython and IronPython. I expect minimal changes will be needed to run Leo's core under Jython. And I *am* talking about a single code base: no translator needed. Edward -------- Edward K.

Re: Pep 3105: the end of print?
> Keep the print name; > Keep the print functionality; > Keep a single code base. Retain the print statement and its functionality, and define an official_print_function to be used in the common code base. I would be satisfied with this (it's what I do now), and it would cause no needless problems for anyone. Having an official print function is a *good* idea, provided it isn't called print :-) Edward -------- Edward K.

Re: Pep 3105: the end of print?
> But that doesn't just happen. True, but it didn't happen as you imply. Leo's core defines a gui-and-platform-independent set of api's which then get instantiated in plugins. Plugins can, and do, use platform-dependent features. For example, the wxWidgets plugin uses the scintilla text widget, something that does not exist by default in Tk/Tkinter. Leo just started to work with IronPython last night, so the details are fresh in my mind. Amazingly, IronPython allows you to point sys.path (IronPython's sys.path, that is) at CPython's Python24\Lib and for the most part IronPython 'just works' with those libs. So all of Leo's core, being free of any gui code, just worked. That is, until it started to load the IronPython plugin :-) At which point I started to have newbie problems with dbgclr, but that's another story... Edward -------- Edward K.

Two idle questions
I've asked these questions on idle-dev with no answer. 1. How can code tell whether it is being run from Idle's debugger? 2. How can code being run from Idle's debugger simulate a breakpoint, such as pdb.set_trace() does? Yes, pdb.set_trace() does work, but I want to enable idle's debugging console and get all of Idle's nice debugging features. Thanks. Edward P.S. I've studied Idle's debugger code for several hours and the answers are not exactly jumping out at me :-) Perhaps it would be good to create wrapper functions (no idea where) to make these tasks easier. Or maybe they already exist? EKR -------- Edward K. Ream email: [EMAIL PROTECTED] Leo: http://webpages.charter.net/edreamleo/front.html -- http://mail.python.org/mailman/listinfo/python-list
