Help creating Controllers on Windows

[Will Canada]

Good day,

Over the last few months, in my free time at work, I have created an instance of https://code.google.com/p/harstorage/ . I have this installed and working successfully.

I have since been looking to modify harstorage, so that I can successfully run casperjs scripts from a web interface.

Everything has gone swimmingly, I have been able to execute the scripts from the web, ect.. however, when I go to create a new controller to add the functionality to the project, I get various issues.

The paster controller command does not seem to work.

When ever I attempt to create a new controller using this method I get  

c:\Python27\Lib\site-packages\harstorage-1.0-py2.7.egg\harstorage\config>paster controller casperjs

Traceback (most recent call last):

  File "C:\python27\Scripts\paster-script.py", line 9, in <module>

    load_entry_point('pastescript==1.7.5', 'console_scripts', 'paster')()

    raise RequirementParseError(msg)

pkg_resources.RequirementParseError: \ must not appear on the last nonblank line

I have an egg_info directory setup in the project, before having that I could not get this far.

Manually creating a controller and adding it to the routes and attempting to access the path results in

Thanks!

This ended up being a syntax error in the controller file on the controller definition. Although the automated paster controller command doesn't work, manual creation is working fine.
