RE: [Fwd: Re: [Regexp] Gnu regexp and port to C#]

[Jonathan . Cogley]

The biggest difference I am noticing while coding in C#, coming from a Java background, is the difference in the design patterns.  Firstly the idea of using Properties instead of get/set.  Also some of the weird ways of doing things like the Synchronized static method on ArrayList which really returns a SyncArrayList (although you wouldn't easily know that looking at their docs).  It seems to me that you may need to rethink the design of gnu.regexp if it is to be built in a C# manner.  If you kept the architecture the same then you would have Java style C# code but that would not make your API intuitive for a native C# developer.

Yes... it's a GNU project after all ... We've to be copyleft ... LGPL fell out of favour as the library uses native methods ... So we just followed the GNU ClassPath model of licensing ..

The major issue would IMHO be the behaviour of String.Substring ...

String.Substring(<string>,start,length); // rather than start,end

And of course almost all functions would need their first chars
capitalized ... To comply to the *standard* common in C# ..

The reason I'm asking for someone to help is that , I'm currently
assigned flow analysis in the compiler ... I doubt if I can find time to do the porting effort ...

If this does not work out now ... I'm planning a Java compiler
for DotGNU , and somebody has already started retargetting jikes
to output CIL as well .. (not part of DotGNU)
