Writing rubyish C# or porting ruby code to C#

27 Oct 2013

Since I liked the ruby version for parsing phone numbers, I ported it to C#. In order to avoid having to rewrite to much I did the following:

• To begin with, the entire project was using ruby name convention. This simplifies things.
• Whenever there is a missing method where the behavior of the method is not the same as the C# one, I added an extension method. For instance I implemented a variant of gsub. The behavior of this gsub uses $1 for matching groups (since it’s more natural to remove a bit of code than make a full port).
• I tried to translate different ruby constructs into C#. For instance the lazy pattern found in the library @variable ||= init_variable I had to replace with _variable ?? (_variable=InitVariable())
• After all the tests became green and I had checked in the initial version, it was quite simple to change name convention using ReSharper.

The finished version is available on github
