    For what it is worth, I have an ubuntu linux workstation with the eclipse ide and the pydev addon. It works great for me.

    Yeah, most of the devs are using Eclipse with PyDev.

    Re: development environment for zenoss

    Dear All

     

    Kindly communicate me the exact versions of

     

    1) python

    2) Zenoss

    3) Eclipse IDE etc

     

    When i compile simple python code then it executes. When i import the modules of Zenoss library then i get errors that you are using wrong API version etc.

     

    i tried to compile the following code :

     

    import locale
    from Globals import DTMLFile
    from Globals import InitializeClass
    from Products.ZenUtils.Utils import convToUnits
    from Products.ZenRelations.RelSchema import *
    from Products.ZenModel.ZenossSecurity import ZEN_VIEW, ZEN_CHANGE_SETTINGS
    from Products.ZenModel.DeviceComponent import DeviceComponent
    from Products.ZenModel.ManagedEntity import ManagedEntity
    from Products.ZenUtils.Utils import prepId
    from ZenModelRM import ZenModelRM
    currentVal = cacheRRDValue('toner_toner', default)

     

     

     

    and got following issues :

    Hi Matt,

     

    Kindly communicate the exact versions of

     

    Pydev

    Python

    Eclipse

     

    I have done it many times but did not succeed. I added the correct library paths but still issues. Kindly give the most authentic way to debug zenoss code in Eclipse

     

    Regards

    Re: development environment for zenoss

    I don't know about Eclipse; I just use vim.

     

    Debugging involves nothing more than dropping breakpoints in the code:

     

    import pdb; pdb.set_trace()

     

    Then running Zope, or zenhub, or whatever relevant process in the foreground:

     

    $ zopectl fg

    $ zenhub run -v10

    $ zencommand run -v10

    ...

     

    Then stepping through it the usual pdb way.

     

    You'll get much more information out of Zope if you turn on debug mode, by adding to $ZENHOME/etc/zope.conf:

     

    debug-mode on

     

    I've never used an IDE that didn't just end up getting in the way more often than it helped.

    Hi Lan McCracken

     

    Thanks for the useful information. But i am trying to develop custom Zenpacks so doing this IDE will be pity easy. I am having Eclipse/Pydev integration issues. Again thanks so much.

     

    Hi ALL

    Kindly communicate me the exact versions of Pydev and Eclipse and an authentic way to integrate them. I am having this issue for a long time

     

    Regards

    Re: development environment for zenoss

    Hi All

     

    I again set up the Eclipse/Pydev. When i try to import a module then it is appearing in the dropdown list. But when i try to compile code, it says NO MODULE FOUND. I am attaching the snapshot file.

     

    Regards

    Re: development environment for zenoss

    As with Ian's experience, although I haven't used an IDE since Turbo C, I find that a few xterms, a couple of instances of gvim, and zendmd do me fine.  Here's what I'm doing lately:

     

    1. I make heavy use of test-driven development, simultaneously editing my Unit Tests in one gvim session, and my code in another gvim session right next to it.
    2. As much as possible, I first develop the code that does not depend on any other zope or zenoss components first, and I bury any such module imports so they don't get pulled in until I need them.
    3. When it's time to talk to zope, I either:
      1. Make appropriate CIFS/NFS mounts so that I can edit the code on my workstation, and run it on a test Zenoss box, or
      2. write some ad-hoc shell scripts to scp the code over to the zenoss box for testing, or sometimes I even
      3. Do an svn commit on my workstation and an svn update on the target zenoss box, but that's ugly.
      4. If I used Linux as my main UI, I'd be developing directly on a zenoss test system, but I use cygwin/X under Windows.
    4. I make frequent use of zendmd to test ideas.
    5. In my unit test script, I pull in much of the framework that zendmd uses, so I can do pretty much anything there; I import pdb into my test scripts so that I can run them interactively for debugging.
    6. I make good use of the logging package, even going as far as adding my own logging levels below level 10 (DEBUG) that I call things like TRACE and SUPERTRACE
    7. Don't forget that, especially if you're developing for Enterprise with it's remote collectors, you may need to commit() between certain types of transactions, and not just at the end of your run.

     

    Make things easy on yourself and figre out how to get it working without an IDE first; then you'll at least know where the problem is if you insist on using and IDE.

     

    Oh, and if you're using ZenScriptBase, and also parsing your own command-line arguments, be sure to clear sys.argv[1:] before you grab a DMD, or because ZenScriptBase will parse them again (unless you want to pass them through intentionally).

    I've gotten Zenoss Developer Chip Holden's writeup for PyDev Install and Configure  Hope this helps!
