Re: [nant-dev] Bug?

[Gordon W. <gwe...@od...>]

Regex is doing a greedy match, that is, the (\w+.*)= matches everything up to the last = in the string.  I think that using "-D:(\w+[^=]*)=(\w*.*)" as the regex would cut off the greedy match.  The regex puzzles me.  It says that a property name can be 1 or more word characters, followed by 0 or more of any character - effectively, any non-word character, since you've already matched all the word characters.  I don't remember seeing any definition of what a legal property name is, I suppose that it's any string.  That would allow for properties with names like "= ".  Sure enough, this build file works: 
  
<project default="test" name="GWSSample"> 
 <property name=" " value="this property has a blank name!"/> 
 <property name="= " value="this property is named '= '!"/> 
 <target name="test"> 
  <echo message="${ }"/> 
  <echo message="${= }"/> 
 </target> 
</project>

In trying to pass a db connection string as a property into NAnt I ran into 
a problem: 

With an input parameter such as 
-D:foobar="blah=true;bleck=false;Provider=SpamSoft" 

Then name matches to : "foobar=blah=true;bleck=false;Provider" value to : 
"SpamSoft" 

NAnt.cs line 64: 
Match match = Regex.Match(arg, @"-D:(\w+.*)=(\w*.*)"); 

Any idea on how to fix this. I am a regexp neophyte.
