Python Paste
Whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Python Paste brings consistency to Python web development and web application installation, providing tools for both developers and system administrators.

Dropping , just trying with .

Since has gone v1, I'll upgrade. Since it uses , that's easy:

You create a new app with paster create (you can have different Templates). There are 2 sample apps: a that uses a back-end, and a [File Browser] (which uses and a number of other libraries).

I tried a create without naming a template at all: 

 ~/Documents/flux billseitz$ paster create flux
Selected and implied templates:
  PasteScript#basic_package  A basic setuptools-enabled package
Variables:
  package:  flux
  project:  flux
Creating template basic_package
Enter version (Version (like 0.1)) ['']: 0.1
(snip)
Enter zip_safe (True/False: if the package can be distributed as a .zip file) [False]: 
Creating directory ./flux
  Recursing into +package+
    Creating ./flux/flux/
    Copying __init__.py to ./flux/flux/__init__.py
  Copying setup.cfg to ./flux/setup.cfg
  Copying setup.py_tmpl to ./flux/setup.py
Running /Library/Frameworks/Python.framework/Versions/2.4/Resources/Python.app/Contents/MacOS/Python setup.py egg_info

An app includes directories: (app-name), docs, and tests, plus a setup.py file. I think it also includes a setup.cfg file and an (app-name).egg-info directory.

Here's some explanation of writing , but it doesn't tie into the app just created. Would you put this code into __init__.py?

Things seemed odd, so I tried again specifying 'basic_template': 

 ~/Documents/flux billseitz$ paster create flux template=basic_package
Selected and implied templates:
  PasteScript#basic_package  A basic setuptools-enabled package
Variables:
  package:   flux
  project:   flux
  template:  basic_package
Creating template basic_package
Enter version (Version (like 0.1)) ['']: 0.1
(snip)
Enter zip_safe (True/False: if the package can be distributed as a .zip file) [False]: 
Creating directory ./flux
  Recursing into +package+
    Creating ./flux/flux/
    Copying __init__.py to ./flux/flux/__init__.py
  Copying setup.cfg to ./flux/setup.cfg
  Copying setup.py_tmpl to ./flux/setup.py
Running /Library/Frameworks/Python.framework/Versions/2.4/Resources/Python.app/Contents/MacOS/Python setup.py egg_info

This didn't seem to make much of a difference. Neither approach gives you a docs subfolder with example_config.ini or devel_config.ini files (the latter seems to be where you do -mapping a-la ).

says I believe the paste_deploy template creates an ini file - basic_template potentially applies to non-web Python packages.

So try that: 

 ~/Documents/flux billseitz$ paster create flux template=paste_deploy
Selected and implied templates:
  PasteScript#basic_package  A basic setuptools-enabled package
Variables:
  package:   flux
  project:   flux
  template:  paste_deploy
Creating template basic_package
Enter version (Version (like 0.1)) ['']: 0.1
(snip)
Enter zip_safe (True/False: if the package can be distributed as a .zip file) [False]: 
Creating directory ./flux
  Recursing into +package+
    Creating ./flux/flux/
    Copying __init__.py to ./flux/flux/__init__.py
  Copying setup.cfg to ./flux/setup.cfg
  Copying setup.py_tmpl to ./flux/setup.py
Running /Library/Frameworks/Python.framework/Versions/2.4/Resources/Python.app/Contents/MacOS/Python setup.py egg_info

That didn't do it either.

Jan20'2007 - upgrade all the packages (hadn't done that before), tried again. Still no success.

Even try using template="paste_deploy" but that doesn't work either.

Maybe I'll just create the docs directory/files by hand, or check out the ones that are in the sample folder and copy them...: 

 find . -name devel_conf*
./PasteDeploy-0.5-py2.4.egg/paste/deploy/paster_templates/paste_deploy/docs/devel_config.ini_tmpl
./PasteDeploy-1.1-py2.4.egg/paste/deploy/paster_templates/paste_deploy/docs/devel_config.ini_tmpl
./RhubarbTart-0.6dev_r5247-py2.4.egg/rhubarbtart/paste_templates/rhubarbtart/docs/devel_config.ini_tmpl

That worked, though filename ends in *.ini_templ - but I just rip off the ending bit.

Try launching: 

 ~/Documents/flux/flux billseitz$ paster serve docs/devel_config.ini
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/Current/bin/paster", line 5, in ?

pkg_resources.DistributionNotFound: WSGIUtils

I see the wrong version of paster is running.

Go remove all the old directories in site_packages, try again: 

 paster serve docs/devel_config.ini
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/Current/bin/paster", line 4, in ?
    import pkg_resources

    for dist in working_set.resolve(

    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: PasteScript==0.5.2dev-r5241

Ugh, I suspect I should have deleted via rather than doing it directly. Or maybe it's that paster hasn't been updated: 

 cd /Library/Frameworks/Python.framework/Versions/Current/bin
ls gives    289 20 May  2006 paster
head paster
#!/Library/Frameworks/Python.framework/Versions/2.4/Resources/Python.app/Contents/MacOS/Python
# EASY-INSTALL-SCRIPT: 'PasteScript==0.5.2dev-r5241','paster'
__requires__ = 'PasteScript==0.5.2dev-r5241'
import pkg_resources
pkg_resources.run_script('PasteScript==0.5.2dev-r5241', 'paster')

Yes, I used to have a directory PasteScript-0.5.2dev_r5241-py2.4.egg

Do I need to upgrade that separately from [Paste Script] and [Paste Deploy]? I thought paster was part of [Python Script]...

So I'm going to edit that little paster file by hand...

Then try launching again: 

 paster serve docs/devel_config.ini

I posted on the email list, and Ian responded: You probably have something like "use = egg:${project}" in a config file.

Later play with .
