List Advisory

Chris Calloway — 2008-05-16T17:22:11

TriZPUGlians: This is to inform you that soon you will be subscribed to our new python.org email list. Python.net has been dying a slow painful death for some time now and there has been work behind the scenes to get our list moved to python.org for many months. That time has now come. When you are subscribed to the new list, you will be getting a welcome message. It will describe the list purposes, policies, email addresses, and URLs. Your email address subscription is the only thing that will carry over to the new list. That means you will need to set yourself a new email list password. There will be a description in your subscribe email about how to do that. Also, if you receive the list via daily digest or have your subscription set to "no email," you will need to reset that as well *after* setting a new password. Of course, if your subscription is set to "no email," then you won't see this message either. :) There are three of you who are "private" members of this list. That is, we don't know who you are because you chose to keep your subscriptions "private" from the other list of members. So, I guess those three of you are own your own to find a way to resubscribe. I bet the front page of http://trizpug.org might hold a clue how to do that. :) I would like to ask that you send no more emails to triangle-zpug-w9fvoj/KL/tYD4wyRYr9MO4UqaaL+JwI< at >public.gmane.org Our co-founder Tom Bryan of python.net is working with Brad Knowles of python.org to get our list archives moved over to python.org. If you have any questions, you can refer them directly to me, cbc the at sign unc the dot mark edu, instead of this list. Before you do, I ask that you read this email again closely and consider if it is a really important questions first, so I don't get a hundred or so emails to answer personally. Finally, huge gynormous thanks to Tom Bryan, who has run the TriZPUG email list for six years. We will have three owners of the new list, myself, Mark Biggers, and Rob Lineberger. If you are a regular long-standing participant at TriZPUG meetings and also would like to be a list owner, just ping me about it.

Re: scope in nested function calls

Joseph Mack NA3T — 2008-05-11T22:21:57

& thanks Bob too It seems I have to declare the variable global at least at the module level seems reasonable As for the term "nesting" - I was using it in the sense that fnA() calls fnB(), then anything declared in fnA() should be visible to fnB(). At least that was my understanding from a long time ago. However looking in google for "wiki" and "nesting", I find the term nesting is used only for recursive calls by a fn() to itself. I have no idea whether I missunderstood nesting when I first heard it, or the meaning has changed over 40yrs. Writing a fn() inside another fn() apparently is called enclosing in python, although nesting would seem to be a reasonable term for it. http://www.cs.wlu.edu/~necaise/python/Fundamentals/DefiningFunctions Joe

Re: scope in nested function calls

bob gailer — 2008-05-11T21:24:57

First let's note that the functions are not nested. Nested would look like: def bar(): bar_value = 3 def foo(): print bar_value foo() and then the /reference /to bar_value would work (but not assignment). To do what you are asking you'd need to make bar_value global, or create a class and use class properties.

scope in nested function calls

Joseph Mack NA3T — 2008-05-11T17:20:30

I've just moved a piece of code out of a long function into another (lower nested) function and I'd like the lower nested function to still access (write to) variables in the calling function. I'm doing this for readability and so that I can test a couple of different versions of the lower nested function by commenting out calls in the calling function. Here's an example piece of code ------------------------------- #! /usr/bin/python def foo(): print "foo: bar_value %d" %bar_value def bar(): bar_value=1 print "bar: bar_value %d" %bar_value foo() #main() bar() --------- the output is # ./test_scope.py bar: bar_value 1 Traceback (most recent call last): File "./test_scope.py", line 12, in ? bar() File "./test_scope.py", line 9, in bar foo() File "./test_scope.py", line 4, in foo print "foo: bar_value %d" %bar_value NameError: global name 'bar_value' is not defined ------------- I can't use "global bar_value" inside foo(), since bar_value isn't global. bar_value isn't local, enclosed, global or built-in (AFAIK). Is there a way to write to variables in a calling function? (If I have to pass all variables as parameters, I'd rather leave the code inside the original function). Thanks Joe

partial write up of last night's plone jam

Rob Lineberger — 2008-05-08T16:03:00

Rob had a need to browse content from a page template and wanted to use the ATReferenceBrowserWidget to do so. Getting ATReferenceBrowserWidget to work in an AT schema is straightforward. In fact, in a tip that newcomer Jonathan Schisler showed us, you can make all of your reference fields into ATReferencBrowsers by setting two tagged values on the "content" package in UML: Tag = imports Value = from Products.ATReferenceBrowserWidget.ATReferenceBrowserWidget import ReferenceBrowserWidget Tag = default:widget:Reference Value = ReferenceBrowserWidget Then any reference line you draw between two classes will create a reference field on your content type with a field name of the referenced content type, and that reference field's widget will be an ATReferenceBrowserWidget. But Rob needed to draw a widget on a page template, not on the edit tab of a content type. So Josh Johnson pulled out some old code from his spiffy Trac repository which went a little something like this: Important part #1: the javascript for ATReferenceBrowserWidget: ``````````````````````````````````````````` The title Important part #2: using ATReferenceBrowserWidget: ``````````````````````````````````````````` My Field It is important to note two things about this solution. One, it is context dependent, so if the current context doesn't have a field in its schema called otherGenelist the page template will barf. Two, you shouldn't be doing this anyway. You should really be using Zope's formlib and use Z3 style adapters, interfaces, browser.zcml, and other cool stuff which only ubercool people grasp.

And apparently, that patch is totally unnecessary if you simply install AGX with: easy_install http://svn.plone.org/svn/archetypes/ArchGenXML/trunk/ I had this suspicion and should have check it before patching setup.py. This tells me that distutils and setuptools are not a compatible as advertized. At least not downwardly. So I won't be submitting this patch after all.

Re: Quick IRC Cheat Sheet

Chris Calloway — 2008-05-08T15:14:21

BTW, here is the patch: http://trac.secoora.org/portal/browser/RAMembers/trunk/RAMembers/archgenxml.setup.py.patch I'm trying to get this into the AGX product trunk. It turned out last night that I don't have commit on Archetypes. So I'll work with the developers on their email list to either get them to accept the patch or get privileges to at least branch in the Archetypes svn.

Also /leave is very useful for just signing off one channel while leaving the others up. I guess if nothing else, we can have a lightning talk on irc and #trizpug at the May meeting. Josh, thanks for all your help at the Plone Jam last night. Folks, Josh got Rob all fixed up on a problem we've been joking about on the #trizpug channel for weeks. And thanks to Mark who sat there with me until 9:30pm while I got the ArchGenXML patch finished.

I highly recommend joining the Wingware users list: http://wingware.com/lists/wingide It is the best support list I have ever seen. In fact, Wingware support alone makes Wing a really good deal.
