Rubies:

Besides .gsub(’,’, ‘’).to\_i, what’s a good way to un-delimit a big  
number?

Ideally, it should be the reverse of Rails’s number\_with\_delimiter…

I would be quite happy with gsub, but if you want another shot on it  
you might do  
scan(/\d/).join  
or  
scan( /[+\d-]).join

str.delete “,”

If you like to check the syntax:

str.gsub /,(\d\d\d)\b/, “\1”

Txbut - imagine if number\_with\_delimiter magically imbued your string  
with  
locale awareness (like the C++ imbue do).

We got anything high-level like that? Some cultures reverse the roles of  
commas  
& dots. (I don’t rly need locales myself; I’m just annoying the envelop  
here…)

I think the real issue here is getting those cultures to use commas and  
dots correctly.

The near-term winnah! I didn’t know .delete() would do them all…

It’s for Cucumber tables, so if it’s in-house, I don’t need to annoy my  
clients.  
If I could get them to author the tables anyway…
