Hi,

Sorry if this is already discussed somewhere but after a trawl through  
this forum I couldn’t find what the state of play is with regular  
expression support in IronRuby.

I took a look at the IronRuby.Libraries assembly and saw the comment  
below so I’ve hazarded a guess the guts of regular expression support  
for IronRuby is still on the ToDo list? In which case it will be a while  
before the /^.+/ constructs can be used?

“// TODO: this implementation is totally wrong, but this is a  
placeholder for a couple of weeks until  
// jomes gets a real implementation of regex. This is only here to  
enable the spec running harness.”

Regards,

Aaron

Yes, it’s still on todo list. It’s right after ‘eval’.

I was able to get a JSON parser working in IronRuby, and that heavily  
relies on Regex support.

Thanks for the replies!

I have wrapped up the .Net Regex.Match method as an interim measure but  
look forward to the much cleaner Ruby =~ and /…/ approach.
