PythonWin/Textpad, external import of Zope module and Persistence
Hi, I'm trying to setup to run with either TextPad, which can run external program like python scripts and then parse the result and making Traceback lines linked to the line/file where the error occurred. Or try using Python which has an build in debugger which I like to be able to use. The first problem I encounter in both scenarios is that when a file "import Globals" which in its turn "from Persistence import Persistent", this fails. Mostly because Persistence is "hot patched" by ZODB. Is there any smart way to setup a "virtual Zope" environment without importing Zope (which mounts the Data.fs) or by importing Zope by in a light way without mounting a storage or just mounting a lights storage. The only thing I want to do in this first phase is to be able to make syntax/sanity checks.

The only thing I want to do in this first phase is to be able to make syntax/sanity checks.
I use something like this for writing and testing external methods, having TextPad run the same python zope uses: if __name__ == '__main__': class EmptyClass: pass REQUEST = EmptyClass() REQUEST.form = {'sortSeq' : 'Date'} #REQUEST.form = {'sortSeq' : 'Item'} print BacklogDetail(REQUEST=REQUEST) -- Emile van Sebille emile@fenx.com ---------

No sure exactly what you're trying to do here, can you privde more detail?

'import Zope' is the only sane thing I can think you'd want to do. Zope has lots of magic that happens when you do that, and unless you do that, things won't behave as you expect. You will need to mount the ZODB, but if you use ZEO then this isn't a problem as your webserver can mount the same storage. cheers, Chris

Well, I solved "the problem" another way, when I realized that I could parse the Stupid Log File and make traceback's clickable in that file: I added a small python script that only gives me the latest stuff in the SLF, and it works quite nice. Now when I get an error I just press CTRL-1 inside Textpad and I get the traceback, click on the error rows and it will automatically open the correct file and scroll to the row where the error occured. For anyone using TextPad on Windows this should quite a time saver. (I know that I forgot to implement a check for if the SLF has been reseted, something my Zope start-up script does everytime I restart the server. http://www.zope.org/Members/johanc/Tips_and_HowTos/textpad_tooltips_howto It's almost like having a RAD tool for Zope. Well not really, but it's an improvement. It should also be possible to make a small script that takes a input file with REQUEST information and then make the HTTP request to the development server and return any traceback messages from the reply to TextPad. (SLF only shows error messages when a product is refreshed, this way it should be possible to retrieve traceback from the running code. (Interactive debugging has to wait, but in Windows it would be terrific to use PythonWin for the task. But starting Zope from within PythonWin usually has the effect of PythonWin hangling. I might be because I have a really slow laptop :-)

I think I have a look at how unit test does this, when I have the time. It would probably solve my problems. Running UnitTest from within TextPad or PythonWin would be a nice way to develop thing in. (Unfortunately I'm not up in speed with writing UnitTests) Thanks. Johan
