I saved this in a file called diagnostics.py. So using it (you’ll need to be in the same directory as diagnostics.py or have added diagnostics.py to your path – more info can be found here: http://docs.python.org/tutorial/modules.html#the-module-search-path) is simply a matter of doing something like this:

from diagnostics import is_assembly_debug_build
is_assembly_debug_build([absolute_path_to_your_dll])

If you’re interested you can grab a copy of diagnostics.py from http://gist.github.com/206177

Have fun

As the Chiron tool is in the Microsoft SDK’s folder, I am presuming that you will need to install the Silverlight 2.0 SDK first (as well as the Silverlight 2.0 runtime of course). These can be downloaded from here:

• Silverlight 2.0 Runtime
• Silverlight 2.0 SDK

Have fun!

1. Download and unpack DLRConsole.zip from http://silverlight.net/Samples/1.1/DLR-Console/DLRConsole.zip
2. Added the following to my Apache httpd.conf file:

    <VirtualHost 127.0.0.1>
            ServerName DLRConsole
            DocumentRoot "C:/dev/DLRConsole"
            AddType text/python .py
            AddType text/jscript .jsx
   
            DirectoryIndex index.htm index.html
   </VirtualHost>
   
   <Directory "C:/dev/DLRConsole">
            Options Indexes MultiViews
            AllowOverride None
            Order allow,deny
            Allow from all
   
            DirectoryIndex index.htm index.html
   </Directory>
   

3. I also set up the following in my hosts file (typically located on Windows at C:WINDOWSSYSTEM32DRIVERSETCHOSTS):
   127.0.0.1 dlrconsole
4. Re-start Apache and point your browser to http://dlrconsole

You may need to comment out any other Python handlers in you httpd.conf file and add them on a per <Directory> basis, but obviously if you’ve got loads of Python-based sites on your Apache installation then your mileage may vary. Fortunately this wasn’t an issue for me so the following was sufficient:

AddHandler cgi-script .pl
#AddHandler cgi-script .py
