running a single test with rspec

Assuming 31 is the line at which your test starts, do this:

rspec some.spec:31

some treetop debug tips

Treetop seems pretty nice, but information on it’s usage is kind of scattered all over internet . Here are a few tips that I used to debug grammars:

1. You can try a specific rule by writing this:
   
tree = parser.parse(content,:root => "rule_name")

2. I usually have my code structured like this, to get some info about where the parser chokes:

   
   if tree
       puts "succesful"
   else
       puts "unsuccesful at #{parser.index}"
       puts parser.failure_reason
   end
   

Hope this helps you as much as it helped me.

unknown encoding: cp0

If you receive this when deploying django on apache, it’s because you have something like:

print "Something %s" % value

The fix is to change it to:

print "Something %s" % str(value)

easy xml parsing in c#

Just a simple usage example:

using System.Xml;
...
XmlDocument doc = new XmlDocument();
// loading a file
doc.Load("file.xml");

// searching for multiple nodes via XPath; this will select all  elements wherever they may be
XmlNodeList books = doc.SelectNodes("//books");

foreach(XmlNode node in books)
{
   // getting attributes; assuming <book Author="Whatever">
   XmlAttribute author = node.Attributes["Author"];
   string value = author.Value;
}
