SmartWizard released

Hello everyone, after a long night with a nice thunderstorm here in Nuremberg, I got the SmartWizard (first version) finished. Oh, you want to know what SmartWizard is? SmartWizard is a framework to generate Wizards for all sort of applications. The wizards are designed for the End User, so I tried to put some of the common Wizard features in it. ....... if this is getting confusing at any point of time, just jump to the bottom and try it ;-) ....... The wizard framework uses a very simple, almost totally in DTML implemented API. All of the required DTML Methods are generated and even pre-filled, so that you can view the wizard as soon as you got your first page written. Wizard Pages are the actual screens you are going to see. They also have always an action associated with them, so you can do some result analysis before going on to the next page. In order to make it even easier, I have also built a small Template Engine, with which you can register new Page templates, in case you have some Pages, which occur over and over again. Currently I have implemented four Page templates: o Wizard Form Page - This type of pages contains Entry Forms which are implemented using the great Formulator. o Wizard Section Page - This type of page displays a SmartSection as its main content. Later I want to use it to manipulate the Wizard right from the view. o Wizard Products Page - This page checks whether a list of required Products is already installed on the current Zope location. This is in particular useful for Installer Wizards, like the Proiektor Installer. o Wizard Tree Page - This page's purpose is to display an object tree and let's you choose an object from the list. You can choose in the Properties, which meta-types are being shown and what the start/default object is. I would love for people (I mean you guys) to come up with ideas for some new Page Templates!

Hello everyone! OrderedFolder (which is used by SmartWizard) is mainly a little patch to the _setObject and _delObject method of the ObjectManager to support 'ordering' in ObjectManager-derived objects. It is a really tiny adjustment, so I hope DC will put it in the core somewhen, since it won't effect performance. But in this release I added some support classes (or mix-in --> I just don't like the word), which allow you additionally to choose the meta-types that are shown in the Add list and I put the _is_transparent attribute into the Properties, so that you can activate and deactivate transparency (this required TranparentFolders of course). In the next release I am probably going to rename the Product to ConfigurableFolder, since the current title is too confusing.

Speed up the learning curve
by Rene Pijlman 28 Jun '01

28 Jun '01

A suggestion to cut the Zope learning curve down by half a day... When the programmer forgets the docstring in a method of a Python-based product, instead of saying "Sorry, the requested resource does not exist." Zope could say: "Sorry, this method has no docstring." Yes, I know this behaviour is well-documented. But the message gives no clue to lead the unwary newbie from the error to the documentation. There are so many useful things I could have done in this half day :-/ Regards, René Pijlman

>So what does it do? :) It is a general Wizard Builder with which you could build a Wizard that asks for all the necessary information to auto-generate a Python Product (for example). >What I'm thinking is this: maybe use SmartWizard to meta-program you >Python Product; that creates a definition file(s) of some sort which is >sent to mk-zprod; mk-zprod consults the WarpFramework do make sure we >don't create too much work for ourselves, and also provides us with nice >default HTML/DTML-pages, and finally, Formulator could be used to do >validation on those HTML/DTML-pages. Exactly that. But the SmartWizard would provide you with a framework to build this "Make New Python Product Wizard". If I get far enough, I will release the pre alpha today, just you see the proof of concept... >Or are we talking past eachother here? Nope, we don't. But SmartWizard is a more general tool than you were thinking of it. >It would be very cool to have a tool like that. I agree. It is annoying to code all that stuff all the time.

ZPL and GPL
by Shane Hathaway 27 Jun '01

27 Jun '01

According to management, there's a zope-license list somewhere and we expect to move to a GPL compatible license. Paul says: "I think the goal should be for Zope and Python to converge on the same license, with perhaps the new license being some off-the-shelf license like Apache's." Shane

They will probably lose developer mindshare. Given how important this is to Zope's growth (and to DC's growth, as a result), this is far far more important than the karma from switching to the far less flexible GPL. Your argument seems to be that DC would want to control other companies ability to make distributions derived from Zope - unless they've been hiding this nefarious plan from the community, this doesn't seem to be an objective for them. As far as a contributor to Zope wanting to keep their work free, then if the ZPL is GPL compatible, they can make their components GPLd.

I want to add the Formulator and SmartSections WizardPage Templates to the system and make it better looking before the release tonight (or more in the morning).

Okay, okay...I stayed up and typed it down pretty quick (2 hours). I attached it to this mail. It is plain text, since I was too lazy to do it in HTML. It might be a little unstructured, but I am too tired to fix that now.

Spell checking module
by Remi Delon 27 Jun '01

27 Jun '01

Hello, I have a website where users can post messages (using a textarea). I would like to be able to spell-check what they submit and notify them of possible mistakes. (much like the online spell-checker of hotmail that I'm using right now :-)) Has anybody ever written anything for zope that does something similar ? I was thinking of using ispell, maybe through a pipe ? A search on "ispell" or even "spell" on the zope.org website doesn't give any interesting result (same on python.org) Thanks. Rémi. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
